Legal battles over President Donald Trump’s executive order to end birthright citizenship continued on July 10, 2025, after a New Hampshire federal district judge issued a preliminary injunction that will, if it’s not reversed, prevent federal officials from enforcing the order nationally.

The ruling by U.S. District Judge Joseph Laplante, a George W. Bush appointee, asserts that this policy of “highly questionable constitutionality … constitutes irreparable harm.”

In its ruling in late June, the Supreme Court allowed the Trump administration to deny citizenship to infants born to undocumented parents in many parts of the nation where individuals or states had not successfully sued to prevent implementation – including a number of mid-Atlantic, Midwest and Southern states.

Trump’s executive order limits U.S. citizenship by birth to those who have at least one parent who is a U.S. citizen or legal permanent resident. It denies citizenship to those born to undocumented people within the U.S. and to the children of those on student, work, tourist and certain other types of visas.

The preliminary injunction is on hold for seven days to allow the Trump administration to appeal.

The June 27 Supreme Court decision on birthright citizenship limited the ability of lower-court judges to issue universal injunctions to block such executive orders nationwide.

Laplante was able to avoid that limit on issuing a nationwide injunction by certifying the case as a class action lawsuit encompassing all children affected by the birthright order, following a pathway suggested by the Supreme Court’s ruling.

Pathways beyond universal injunctions

In its recent birthright citizenship ruling, Trump v. CASA, the Supreme Court noted that plaintiffs could still seek broad relief by filing such class action lawsuits that would join together large groups of individuals facing the same injury from the law they were challenging.

And that’s what happened.

Litigants filed suit in New Hampshire’s district court the same day that the Supreme Court decided CASA. They asked the court to certify a class consisting of infants born on or after Feb. 20, 2025, who would be covered by the order and their parents or prospective parents. The court allowed the suit to proceed as a class action for these infants.

What if this injunction doesn’t stick?

If the U.S. Court of Appeals for the 1st Circuit or the Supreme Court invalidates the New Hampshire court’s newest national injunction and another injunction is not issued in a different venue, the order will then go into effect anywhere it is not currently barred from doing so. Implementation could begin in as many as 28 states where state attorneys general have not challenged the Trump birthright citizenship policy if no other individuals or groups secure relief.

As political science scholars who study race and immigration policy, we believe that, if implemented piecemeal, Trump’s birthright citizenship order would create administrative chaos for states determining the citizenship status of infants born in the United States. And it could lead to the first instances since the 1860s of infants being born in the U.S. being denied citizenship categorically.

States’ role in establishing citizenship

Almost all U.S.-born children are issued birth certificates by the state in which they are born.

The federal government’s standardized form, the U.S. standard certificate of live birth, collects data on parents’ birthplaces and their Social Security numbers, if available, and provides the information states need to issue birth certificates.

But it does not ask questions about their citizenship or immigration status. And no national standard exists for the format for state birth certificates, which traditionally have been the simplest way for people born in the U.S. to establish citizenship.

If Trump’s executive order goes into effect, birth certificates issued by local hospitals would be insufficient evidence of eligibility for federal government documents acknowledging citizenship. The order would require new efforts, including identification of parents’ citizenship status, before authorizing the issuance of any federal document acknowledging citizenship.

Since states control the process of issuing birth certificates, they will respond differently to implementation efforts. Several states filed a lawsuit on Jan. 21 to block the birthright citizenship order. And they will likely pursue an arsenal of strategies to resist, delay and complicate implementation.

While the Supreme Court has not yet confirmed that these states have standing to challenge the order, successful litigation could bar implementation in up to 18 states and the District of Columbia if injunctions are narrowly framed, or nationally if lawyers can persuade judges that disentangling the effects on a state-by-state basis will be too difficult.

Other states will likely collaborate with the administration to deny citizenship to some infants. Some, like Texas, had earlier attempted to make it particularly hard for undocumented parents to obtain birth certificates for their children.

Potential for chaos

If the Supreme Court rejects attempts to block the executive order nationally again, implementation will be complicated.

That’s because it would operate in some places and toward some individuals while being legally blocked in other places and toward others, as Justice Sonia Sotomayor warned in her Trump v. CASA dissent.

Children born to plaintiffs anywhere in the nation who have successfully sued would have access to citizenship, while other children possibly born in the same hospitals – but not among the groups named in the suits – would not.

Babies born in the days before implementation would have substantially different rights than those born the day after. Parents’ ethnicity and countries of origin would likely influence which infants are ultimately granted or denied citizenship.

That’s because some infants and parents would be more likely to generate scrutiny from hospital employees and officials than others, including Hispanics, women giving birth near the border, and women giving birth in states such as Florida where officials are likely to collaborate enthusiastically with enforcement.

The consequences could be profound.

Some infants would become stateless, having no right to citizenship in another nation. Many people born in the U.S. would be denied government benefits, Social Security numbers and the ability to work legally in the U.S.

With the constitutionality of the executive order still unresolved, it’s unclear when, if ever, some infants born in the U.S. will be the first in the modern era to be denied citizenship.

Flash floods like the one that swept down the Guadalupe River in Texas on July 4, 2025, can be highly unpredictable. While there are sophisticated flood prediction models and different types of warning systems in some places, effective flood protection requires extensive preparedness and awareness.

It also requires an understanding of how people receive, interpret and act on risk information and warnings. Technology can be part of the solution, but ultimately people are the critical element in any response.

As researchers who study emergency communications, we have found that simply providing people with technical information and data is often not enough to effectively communicate the danger and prompt them to act.

The human element

One of us, Keri Stephens, has led teams studying flood risk communication. They found that people who have experienced a flood are more aware of the risks. Conversely, groups that have not lived through floods typically don’t understanding various flood risks such as storm surges and flash floods. And while first responders often engage in table-top exercises and drills – very important for their readiness to respond – there are only a few examples of entire communities actively participating in warning drills.

Messages used to communicate flood risk also matter, but people need to receive them. To that end, Keri’s teams have worked with the Texas Water Development Board to develop resources that help local flood officials sort through and prioritize information about a flood hazard so they can share what is most valuable with their local communities.

The commonly used “Turn Around Don’t Drown” message, while valuable, may not resonate equally with all groups. Newly developed and tested messages such as “Keep Your Car High and Dry” appeal specifically to young adults who typically feel invincible but don’t want their prized vehicles damaged. While more research is needed, this is an example of progress in understanding an important aspect of flood communication: how recipients of the information make decisions.

Interviews conducted by researchers often include responses along these lines: “Another flash flood warning. We get these all the time. It’s never about flooding where I am.” This common refrain reveals a fundamental challenge in flood communication. When people hear “flood warning,” they often think of different things, and interpretations can vary depending on a person’s proximity to the flooding event.

Some people equate flood warnings with streamflow gauges and sensors that monitor water levels – the technical infrastructure that triggers alerts when rivers exceed certain thresholds. Others think of mobile phone alerts, county- or geographic-specific notification systems, or even sirens.

Beyond technologies and digital communication, warnings still come through informal networks in many communities. Emergency managers directly coordinate with and share information with major businesses and organizations, saying, “Hey, John, be sure you have somebody up tonight watching the National Weather Service alerts and rivers.”

This human-centered approach, similar to neighborhood-level systems we have studied in Japan, can provide direct confirmation that warnings have been received. This is something mass media and mobile systems cannot guarantee, especially during infrastructure failures such as power and cell tower outages.

Effective messages

Research shows that effective warning messages need to include five critical components: a clear hazard description, location-specific information, actionable guidance, timing cues and a credible source. The Federal Emergency Management Agency’s integrated public alert and warning system message design dashboard assists authorities in rapidly drafting effective messages.

This warning system, known as IPAWS, provides nationwide infrastructure for wireless emergency alerts and Emergency Alert System messages. While powerful, IPAWS has limitations − not all emergency managers are trained to use it, and messages may extend beyond intended geographic areas. Also, many older mobile devices lack the latest capabilities, so they may not receive the most complete messages when they are sent.

Hyperlocal community opt-in systems can complement IPAWS by allowing residents to register for targeted notifications. These systems, which can be run by communities or local agencies, face their own challenges. People must know they exist, be willing to share phone numbers, and remember to update their information. Social media platforms add another communication channel, with emergency managers increasingly using social media to share updates, though these primarily reach only certain demographics, and not everyone checks social media regularly.

The key is redundancy through multiple communication channels. Research has found that multiple warnings are needed for people to develop a sense of urgency, and the most effective strategy is simple: Tell another person what’s going on. Interpersonal networks help ensure the message is delivered and can prompt actions. As former Natural Hazards Center Director Dennis Mileti observed: The wireless emergency alerts system “is fast. Mama is faster.”

Warning fatigue

Professionals from the National Weather Service, FEMA and the Federal Communications Commission, along with researchers, are increasingly concerned about warning fatigue – when people tune out warnings because they receive too many of them.

However, there is limited empirical data about how and when people experience warning fatigue – or about its impact.

This creates a double bind: Officials have an obligation to warn people at risk, yet frequent warnings can desensitize recipients. More research is needed to determine the behavioral implications of and differences between warnings that people perceive as irrelevant to their immediate geographic area versus those that genuinely don’t apply to them. This distinction becomes especially critical when people might drive into flooded areas outside their immediate vicinity.

The key to effective emergency communication is to develop messages that resonate with specific audiences and build community networks that complement technological systems. We are now studying how to do this effectively in the United States and internationally. It’s also important to apply behavioral insights to the design of every level of communication warning systems. And it’s important to remember to test not just the technology but the entire end-to-end system, from threat identification to community response.

Finally, maintaining true redundancy across multiple communication channels is an important strategy when trying to reach as many people as possible. Technology supports human decision-making, but it doesn’t replace it.

Imagine walking into your doctor’s office feeling sick – and rather than flipping through pages of your medical history or running tests that take days, your doctor instantly pulls together data from your health records, genetic profile and wearable devices to help decipher what’s wrong.

This kind of rapid diagnosis is one of the big promises of artificial intelligence for use in health care. Proponents of the technology say that over the coming decades, AI has the potential to save hundreds of thousands, even millions of lives.

What’s more, a 2023 study found that if the health care industry significantly increased its use of AI, up to US$360 billion annually could be saved.

But though artificial intelligence has become nearly ubiquitous, from smartphones to chatbots to self-driving cars, its impact on health care so far has been relatively low.

A 2024 American Medical Association survey found that 66% of U.S. physicians had used AI tools in some capacity, up from 38% in 2023. But most of it was for administrative or low-risk support. And although 43% of U.S. health care organizations had added or expanded AI use in 2024, many implementations are still exploratory, particularly when it comes to medical decisions and diagnoses.

I’m a professor and researcher who studies AI and health care analytics. I’ll try to explain why AI’s growth will be gradual, and how technical limitations and ethical concerns stand in the way of AI’s widespread adoption by the medical industry.

Inaccurate diagnoses, racial bias

Artificial intelligence excels at finding patterns in large sets of data. In medicine, these patterns could signal early signs of disease that a human physician might overlook – or indicate the best treatment option, based on how other patients with similar symptoms and backgrounds responded. Ultimately, this will lead to faster, more accurate diagnoses and more personalized care.

AI can also help hospitals run more efficiently by analyzing workflows, predicting staffing needs and scheduling surgeries so that precious resources, such as operating rooms, are used most effectively. By streamlining tasks that take hours of human effort, AI can let health care professionals focus more on direct patient care.

But for all its power, AI can make mistakes. Although these systems are trained on data from real patients, they can struggle when encountering something unusual, or when data doesn’t perfectly match the patient in front of them.

As a result, AI doesn’t always give an accurate diagnosis. This problem is called algorithmic drift – when AI systems perform well in controlled settings but lose accuracy in real-world situations.

Racial and ethnic bias is another issue. If data includes bias because it doesn’t include enough patients of certain racial or ethnic groups, then AI might give inaccurate recommendations for them, leading to misdiagnoses. Some evidence suggests this has already happened.

Data-sharing concerns, unrealistic expectations

Health care systems are labyrinthian in their complexity. The prospect of integrating artificial intelligence into existing workflows is daunting; introducing a new technology like AI disrupts daily routines. Staff will need extra training to use AI tools effectively. Many hospitals, clinics and doctor’s offices simply don’t have the time, personnel, money or will to implement AI.

Also, many cutting-edge AI systems operate as opaque “black boxes.” They churn out recommendations, but even its developers might struggle to fully explain how. This opacity clashes with the needs of medicine, where decisions demand justification.

But developers are often reluctant to disclose their proprietary algorithms or data sources, both to protect intellectual property and because the complexity can be hard to distill. The lack of transparency feeds skepticism among practitioners, which then slows regulatory approval and erodes trust in AI outputs. Many experts argue that transparency is not just an ethical nicety but a practical necessity for adoption in health care settings.

There are also privacy concerns; data sharing could threaten patient confidentiality. To train algorithms or make predictions, medical AI systems often require huge amounts of patient data. If not handled properly, AI could expose sensitive health information, whether through data breaches or unintended use of patient records.

For instance, a clinician using a cloud-based AI assistant to draft a note must ensure no unauthorized party can access that patient’s data. U.S. regulations such as the HIPAA law impose strict rules on health data sharing, which means AI developers need robust safeguards.

Privacy concerns also extend to patients’ trust: If people fear their medical data might be misused by an algorithm, they may be less forthcoming or even refuse AI-guided care.

The grand promise of AI is a formidable barrier in itself. Expectations are tremendous. AI is often portrayed as a magical solution that can diagnose any disease and revolutionize the health care industry overnight. Unrealistic assumptions like that often lead to disappointment. AI may not immediately deliver on its promises.

Finally, developing an AI system that works well involves a lot of trial and error. AI systems must go through rigorous testing to make certain they’re safe and effective. This takes years, and even after a system is approved, adjustments may be needed as it encounters new types of data and real-world situations.

Incremental change

Today, hospitals are rapidly adopting AI scribes that listen during patient visits and automatically draft clinical notes, reducing paperwork and letting physicians spend more time with patients. Surveys show over 20% of physicians now use AI for writing progress notes or discharge summaries. AI is also becoming a quiet force in administrative work. Hospitals deploy AI chatbots to handle appointment scheduling, triage common patient questions and translate languages in real time.

Clinical uses of AI exist but are more limited. At some hospitals, AI is a second eye for radiologists looking for early signs of disease. But physicians are still reluctant to hand decisions over to machines; only about 12% of them currently rely on AI for diagnostic help.

Suffice to say that health care’s transition to AI will be incremental. Emerging technologies need time to mature, and the short-term needs of health care still outweigh long-term gains. In the meantime, AI’s potential to treat millions and save trillions awaits.

Tumors can destroy the blood vessels of muscles even when the muscles are nowhere close to the tumor. That is the key finding of a new study that my colleagues and I recently published in the journal Nature Cancer.

Muscle loss in cancer patients is a major health problem, but the exact causes of how precisely tumors affect muscles remain an active area of research.

Scientists in my lab were curious whether one explanation for the muscle loss in cancer patients could be that the cancer impairs the blood vessels that are necessary to supply nutrients and oxygen to muscles. Healthy blood vessels ensure that blood containing oxygen and nutrients is transported from the heart to all tissues and organs in the body, and then circulates back to the heart. Unhealthy blood vessels lose the ability to circulate sufficient blood and develop leaks, with nutrients seeping into the tissue prematurely and thereby cutting off the supply of nutrients to tissues that are further downstream.

To tackle this question, my colleagues and I worked with several other scientific research teams with expertise in advanced microscopy, cancer research and metabolism. We used animal models to study several kinds of tumors – lung cancer, skin cancer, colon cancer and pancreatic cancer. We consistently observed that the blood vessels in the muscles became fewer and leakier even before the muscle weakness set in.

We also found that tumors release a protein called Activin-A, which acts on blood vessels to cause the leakiness and, ultimately, loss of blood vessels in the muscle. When we used a gene therapy to restore blood vessel health by counteracting the effects of Activin-A, we were able to prevent the muscle loss.

So we examined the muscles of patients who had passed away because of cancer and found that the muscles of cancer patients contained fewer blood vessels than expected.

Why Activin-A matters

Millions of cancer survivors struggle with muscle weakness, which can be so profound that they may have difficulties walking up a couple of flights of stairs or going shopping for groceries on their own.

Severe muscle weakness and muscle loss during cancer is called cancer cachexia, which occurs in up to 80% of patients with advanced cancer.

Recent research indicates that cachexia is far more common among cancer patients than previously suspected, with approximately half the patients who see their cancer doctor for the first time already showing signs of muscle weakness.

Importantly, cachexia can persist even after the cancer is successfully treated and cured. This can have a devastating impact on the quality of life for cancer survivors.

Our discovery that the loss of blood vessel function in the muscles occurs early on during the progression of the cancer suggests that fixing blood vessels in cancer patients and cancer survivors could be a new way to prevent or reverse cachexia.

The reasons for the muscle loss in cancer are complicated and involve poor nutrition due to loss of appetite and inflammation, which are initially caused by the tumor but persist even when the tumor is removed.

What other research is being done

There are currently no treatments approved by the Food and Drug Administration for cachexia, but new therapies are on the horizon.

One such therapy is an antibody drug that targets the molecule GDF-15, a protein that is thought to suppress appetite.

Other studies are using a combination of targeted nutrition and exercise programs to help patients with cancer cachexia regain muscle mass and muscle strength.

All these studies suggest that we will need a combination of approaches to enhance exercise, nutrition, appetite, muscle regeneration and – as we propose – blood vessel health.

What’s next

We are now evaluating drugs and exercise programs that are known to improve blood vessel health. Repurposing these treatments that are traditionally designed for cardiovascular patients could be a rapid way to help cancer patients regain muscle strength.

We hope that our work highlights how important it is for cancer patients to receive comprehensive medical care, which includes improving cardiovascular health and overall quality of life.

The Research Brief is a short take on interesting academic work.

Churches and other houses of worship can endorse political candidates without risking the loss of their tax-exempt status, the Internal Revenue Service said in a legal document the tax-collection agency filed on July 7, 2025. This guidance is at odds with a law Congress passed more than 70 years ago that’s known as the Johnson Amendment and applies to all charitable nonprofits, whether they are secular or religious.

The Conversation U.S. asked Lloyd Hitoshi Mayer, a law professor who has studied the regulation of churches’ political activities, to explain what this statute is, how the IRS seeks to change its purview and why this matters.

What’s the Johnson Amendment?

The Johnson Amendment is a provision that Lyndon B. Johnson added to a tax bill passed by Congress in 1954, when he was a senator. It says that any charity that wants to be tax-exempt under section 501(c)(3) of the Internal Revenue Code cannot “participate in, or intervene in … any political campaign on behalf of … any candidate for public office.” In the U.S., all houses of worship are designated as charities by the IRS.

The IRS has interpreted the Johnson Amendment for more than 70 years to mean that charities cannot speak in favor of political candidates or take any other action that supports or opposes them.

The IRS is prohibited from publicly disclosing audits of specific tax-exempt nonprofits under taxpayer privacy laws, so there’s no way to know the extent to which the law has been enforced. The public only learns about audits tied to possible Johnson Amendment violations if the nonprofit discloses that information or the IRS revoked their tax-exempt status.

However, the IRS did conduct a broad enforcement campaign in the 2000s known as the Political Activity Compliance Initiative. The reports it issued for 2004 and 2006 stated that it had audited hundreds of charities, including churches, for possible Johnson Amendment violations. The IRS generally found that most violations were minor and often inadvertent – warranting no more than a warning letter.

It’s unknown whether any nonprofits lost their tax-exempt status as a result of this initiative, which the IRS appears to have ended in 2008.

There’s only one known instance of a church losing its tax-exempt status because it violated the Johnson Amendment. In that case, a church in Binghamton, New York, published full-page newspaper ads criticizing Bill Clinton during his 1992 presidential campaign.

Why does the Trump administration want to change its enforcement?

The National Religious Broadcasters, two churches and another religious nonprofit sued the IRS in 2024, challenging the constitutionality of the Johnson Amendment on First Amendment free speech and free exercise of religion grounds and on Fifth Amendment due process grounds. The plaintiffs also argued that applying the Johnson Amendment to religious nonprofits violated the federal Religious Freedom Restoration Act.

The plaintiffs and the IRS filed a joint motion on July 7 to settle the case. They asked the U.S. District Court for the Eastern District of Texas to order the IRS not to enforce the Johnson Amendment against the two church plaintiffs. They also asked the court to incorporate in its order a statement that the Johnson Amendment does not apply to “speech by a house of worship to its congregation, in connection with religious services through its customary channels of communication on matters of faith, concerning electoral politics viewed through the lens of religious faith.”

This represents the first time the IRS has said there’s an exception to the Johnson Amendment for houses of worship. While lawmakers have periodically sought to repeal or modify the statute, neither chamber of Congress has ever passed such legislation.

President Donald Trump asserted during his first term that he had “gotten rid of” the Johnson Amendment. But that referred to his 2017 executive order that directed the Treasury Department – to which the IRS belongs – to respect freedom of religion with respect to religious organizations speaking about political issues as “consistent with law.”

Under the IRS interpretation of the Johnson Amendment at the time, it would not have been consistent with law for churches or other religious nonprofits to support or oppose candidates for elected public office.

How might the IRS treat religious political activity differently?

If the court approves this new joint motion, that order will only apply to the two churches that are plaintiffs in the case – not other religious nonprofits or the National Religious Broadcasters that joined them in suing the IRS. But the filing tells other houses of worship that the IRS will not enforce the Johnson Amendment against them for speech to their congregations, at least not during the Trump administration.

I think that the government may have a hard time applying this exception for several reasons.

The IRS will have to determine when a charity is a “church,” the term the IRS uses for a house of worship of any faith. That has become increasingly difficult in recent years, as some organizations that stretch the conventional definition of a church have won IRS recognition as such.

The IRS will also have to clarify what constitutes speech made “in connection with religious services” and what are “customary channels of communication.” For example, it’s unclear whether inviting a political candidate to address the congregation about how their religious faith relates to their candidacy falls within the exception.

Will only conservative politicians benefit?

Establishing this exception does not necessarily give conservative politicians any advantages.

It is true that recent attempts to repeal or modify the Johnson Amendment are associated with conservative Christian groups such as the Alliance Defending Freedom, which represented the plaintiffs in this lawsuit.

But historically, many progressive houses of worship have also pushed against the Johnson Amendment, including Black churches that often serve as political as well as religious centers for their communities.

A Texas Tribune and ProPublica investigation documented apparent violations of the Johnson Amendment in the 2022 midterm elections by almost 20 churches in Texas from across the political spectrum. Interestingly, most of the church leaders involved were aware of the amendment.

Many said they were not violating it because they avoided explicitly endorsing candidates, while at the same time clearly expressing their support for specific candidates by, for example, praying for an individual who was identified to the congregation as a candidate.

How could this new guidance change political campaigning?

Americans generally don’t want to see churches get involved in politics, including majorities in most denominations. Nonetheless, church leaders of all stripes who were already inclined to support particular candidates will probably feel emboldened to explicitly endorse candidates when preaching to their congregations.

There are two ways that this new exception could do more than that.

First, it isn’t limited to sermons by pastors, priests, rabbis, imams and other religious leaders. It extends to any speech to a house of worship’s congregation “in connection with religious services through its customary channels of communication on matters of faith.” It therefore almost certainly includes church bulletins and other written materials distributed as part of a religious service.

What’s less clear is whether “customary channels of communication” includes people who watch religious services streamed over the internet or on TV, rather than just those who attend services in person.

Second, the change will increase pressure on church leaders to support candidates.

For example, George W. Bush’s 2004 campaign reportedly sought to recruit thousands of congregations to distribute campaign information. It’s natural to expect such efforts to multiply and become more direct for both Democratic and Republican candidates from now on.

And church leaders will also likely face pressure from politically active congregants to endorse candidates, and have a harder time resisting it.

Lloyd Hitoshi Mayer previously worked at the law firm of Caplin & Drysdale, Chartered, including when the firm represented All Saints Episcopal Church of Pasadena, California with respect to an IRS audit of the church for allegedly violating the Johnson Amendment. He was not personally involved in this representation.

The burgeoning space industry and the technologies society increasingly relies on – electric grids, aviation and telecommunications – are all vulnerable to the same threat: space weather.

Space weather encompasses any variations in the space environment between the Sun and Earth. One common type of space weather event is called an interplanetary coronal mass ejection.

These ejections are bundles of magnetic fields and particles that originate from the Sun. They can travel at speeds up to 1,242 miles per second (2,000 kilometers per second) and may cause geomagnetic storms.

They create beautiful aurora displays – like the northern lights you can sometimes see in the skies – but can also disrupt satellite operations, shut down the electric grid and expose astronauts aboard future crewed missions to the Moon and Mars to lethal doses of radiation.

I’m a heliophysicist and space weather expert, and my team is leading the development of a next-generation satellite constellation called SWIFT, which is designed to predict potentially dangerous space weather events in advance. Our goal is to forecast extreme space weather more accurately and earlier.

The dangers of space weather

Commercial interests now make up a big part of space exploration, focusing on space tourism, building satellite networks, and working toward extracting resources from the Moon and nearby asteroids.

Space is also a critical domain for military operations. Satellites provide essential capabilities for military communication, surveillance, navigation and intelligence.

As countries such as the U.S. grow to depend on infrastructure in space, extreme space weather events pose a greater threat. Today, space weather threatens up to US$2.7 trillion in assets globally.

In September 1859, the most powerful recorded space weather event, known as the Carrington event, caused fires in North America and Europe by supercharging telegraph lines. In August 1972, another Carrington-like event nearly struck the astronauts orbiting the Moon. The radiation dose could have been fatal. More recently, in February 2022, SpaceX lost 39 of its 49 newly launched Starlink satellites because of a moderate space weather event.

Today’s space weather monitors

Space weather services heavily rely on satellites that monitor the solar wind, which is made up of magnetic field lines and particles coming from the Sun, and communicate their observations back to Earth. Scientists can then compare those observations with historical records to predict space weather and explore how the Earth may respond to the observed changes in the solar wind.

Earth’s magnetic field naturally protects living things and Earth-orbiting satellites from most adverse effects of space weather. However, extreme space weather events may compress – or in some cases, peel back – the Earth’s magnetic shield.

This process allows solar wind particles to make it into our protected environment – the magnetosphere – exposing satellites and astronauts onboard space stations to harsh conditions.

Most satellites that continuously monitor Earth-bound space weather orbit relatively close to the planet. Some satellites are positioned in low Earth orbit, about 100 miles (161 kilometers) above Earth’s surface, while others are in geosynchronous orbit, approximately 25,000 miles (40,000 km) away.

At these distances, the satellites remain within Earth’s protective magnetic shield and can reliably measure the planet’s response to space weather conditions. However, to more directly study incoming solar wind, researchers use additional satellites located farther upstream – hundreds of thousands of miles from Earth.

The U.S., the European Space Agency and India all operate space weather monitoring satellites positioned around the L1 Lagrange point – nearly 900,000 miles (1,450,000 km) from Earth – where the gravitational forces of the Sun and Earth balance. From this vantage point, space weather monitors can provide up to 40 minutes of advance warning for incoming solar events.

Advance warning for space weather

Increasing the warning time beyond 40 minutes – the current warning time – would help satellite operators, electric grid planners, flight directors, astronauts and Space Force officers better prepare for extreme space weather events.

For instance, during geomagnetic storms, the atmosphere heats up and expands, increasing drag on satellites in low Earth orbit. With enough advance warning, operators can update their drag calculations to prevent satellites from descending and burning up during these events. With the updated drag calculations, satellite operators could use the satellites’ propulsion systems to maneuver them higher up in orbit.

Airlines could change their routes to avoid exposing passengers and staff to high radiation doses during geomagnetic storms. And future astronauts on the way to or working on the Moon or Mars, which lack protection from these particles, could be alerted in advance to take cover.

Aurora lovers would also appreciate having more time to get to their favorite viewing destinations.

The Space Weather Investigation Frontier

My team and I have been developing a new space weather satellite constellation, named the Space Weather Investigation Frontier. SWIFT will, for the first time, place a space weather monitor beyond the L1 point, at 1.3 million miles (2.1 million kilometers) from Earth. This distance would allow scientists to inform decision-makers of any Earth-bound space weather events up to nearly 60 minutes before arrival.

Satellites with traditional chemical and electric propulsion systems cannot maintain an orbit at that location – farther from Earth and closer to the Sun – for long. This is because they would need to continuously burn fuel to counteract the Sun’s gravitational pull.

To address this issue, our team has spent decades designing and developing a new propulsion system. Our solution is designed to affordably reach a distance that is closer to the Sun than the traditional L1 point, and to operate there reliably for more than a decade by harnessing an abundant and reliable resource – sunlight.

SWIFT would use a fuelless propulsion system called a solar sail to reach its orbit. A solar sail is a hair-thin reflective surface – simulating a very thin mirror – that spans about a third of a football field. It balances the force of light particles coming from the Sun, which pushes it away, with the Sun’s gravity, which pulls it inward.

While a sailboat harnesses the lift created by wind flowing over its curved sails to move across water, a solar sail uses the momentum of photons from sunlight, reflected off its large, shiny sail, to propel a spacecraft through space. Both the sailboat and solar sail exploit the transfer of energy from their respective environments to drive motion without relying on traditional propellants.

A solar sail could enable SWIFT to enter an otherwise unstable sub-L1 orbit without the risk of running out of fuel.

NASA successfully launched its first solar sail in 2010. This in-space demonstration, named NanoSail-D2, featured a 107-square-foot (10 m² ) sail and was placed in low Earth orbit. That same year, the Japanese Space Agency launched a larger solar sail mission, IKAROS, which deployed a 2,110 ft² (196 m² ) sail in the solar wind and successfully orbited Venus.

The Planetary Society and NASA followed up by launching two sails in low Earth orbit: LightSail, with an area of 344 ft² (32 m² ), and the advanced composite solar sail system, with an area of 860 ft² (80 m² ).

The SWIFT team’s solar sail demonstration mission, Solar Cruiser, will be equipped with a much larger sail – it will have area of 17,793 ft² (1,653 m² ) and launch as early as 2029. We successfully deployed a quadrant of the sail on Earth early last year.

To transport it to space, the team will meticulously fold and tightly pack the sail inside a small canister. The biggest challenge to overcome will be deploying the sail once in space and using it to guide the satellite along its orbital path.

If successful, Solar Cruiser will pave the way for SWIFT’s constellation of four satellites. The constellation would include one satellite equipped with sail propulsion, set to be placed in an orbit beyond L1, and three smaller satellites with chemical propulsion in orbit at the L1 Lagrange point.

The satellites will be indefinitely parked at and beyond L1, collecting data in the solar wind without interruption. Each of the four satellites can observe the solar wind from different locations, helping scientists better predict how it may evolve before reaching Earth.

As modern life depends more on space infrastructure, continuing to invest in space weather prediction can protect both space- and ground-based technologies.

Spotted lanternfly season is back in Pennsylvania. The polka-dotted, gray-and-red-winged adult insects make their appearance each July and tend to hang around until December. It’s an unwelcome summer ritual that started in 2014 when the invasive pests were first detected in the U.S.

The Conversation U.S. talked to Flor Acevedo, an assistant professor of entomology at Penn State University, about the bugs and her research on how lanternflies are threatening the state’s vineyards and wine industry.

Does Pennsylvania have many vineyards?

Pennsylvania has more than 400 wineries with about 14,000 acres planted in vineyards, according to the Pennsylvania Wine Association. The industry generates about US$7 billion in total economic activity. Erie County, where I live, has about 70% of Pennsylvania’s vineyard acreage, with the rest scattered across the state.

What do lanternflies do to grapevines?

The spotted lanternfly feeds on many plants, but its preferred hosts are the Tree of Heaven, an invasive plant introduced to Philadelphia from China in 1784, and grapevines.

Extensive feeding by these sap-sucking insects can weaken grapevines and, when combined with other stressors such as diseases or frosty winters, can kill the vines. While spotted lanternflies feed on other important crops such as apple trees, they have been lethal only to grapevines and Tree of Heaven plants.

Feeding can also reduce yield and fruit quality, which affects juice and wine quality.

Tell us about your lanternfly experiments

My lab initially investigated whether spotted lanternflies could survive to adulthood and reproduce when feeding exclusively on grapevines. This would help us determine whether the insects could thrive in regions with extensive grapevine cultivation.

We found they do survive, but their fitness is severely reduced. Insects feeding solely on grapevines had high mortality, slower development and laid fewer eggs when compared with those that had access to a mixed diet of Tree of Heaven and grapevines.

Our next question was whether different grapes would be equally suitable for spotted lanternfly survival and reproduction. In the U.S. we grow native grapevines such as Concord and muscadine as well as vines of European origin. We found that spotted lanternflies did not survive to adulthood when they fed only on muscadine grapevines.

We have also partnered with colleagues specialized in plant science, food science and agricultural economics to investigate the effects of spotted lanternfly feeding on grapevine yield and wine and juice quality.

This research group enclosed both red and white grapevines – Cabernet Franc and Chardonnay – in mesh cages in the field and infested them with between 20 and 350 spotted lanternflies per vine. We wanted to determine the effect of constant adult insect feeding on grapevine yield, fruit sugars and phenolics, which are chemical compounds that are important for wine color, flavor and aroma. We also wanted to know the density of infestation that would induce changes in yield and fruit and wine quality.

We found a decrease in sugar content in the fruit within a single season, as well as a decrease in phenolics in red wine. We also found a reduction in yield after the second year of consecutive insect feeding.

These findings suggest that, if not controlled, spotted lanternfly adult feeding could reduce income to growers by reducing yield and could affect the wine industry by reducing the quality of the drink.

How worried are Pennsylvania winemakers and how are they responding?

Perceptions vary depending on whether the winery or vineyard is in an area that has already been infested.

Those that have been dealing with lanternflies for a few years have established protocols for pest monitoring and applying insecticides. But those that haven’t experienced it yet are concerned about the insect’s arrival on their properties.

Owners of organic vineyards are also concerned, but there are few of those in this region.

Wineries are being affected by spotted lanternflies in at least two ways. First, for those that grow grapes, lanternflies have increased their costs due to the extra labor and insecticide applications needed to control them. Second, for wineries that are agrotourism sites, they need to keep outdoor seating spaces neat and free from lanternflies.

As an entomologist, what do you find most fascinating about these creatures?

Most insects that feed on plants lay their eggs close to a food source for the young to feed on when they hatch. But spotted lanternflies lay their eggs on almost anything – car tires, field equipment, rocks, fabrics, old wood, cardboard. This behavior facilitates the insect’s dispersal, as eggs can be easily transported without being noticed. Once the eggs hatch, the nymphs search for young plant shoots or herbaceous plants to eat.

Anything else people in Pennsylvania should know as they see lanternflies again this summer?

I think it’s important for the public to know that, as pretty as some of us may find spotted lanternflies, these insects are invasive, damaging and affecting the state economy. Everybody can help stop the spread of these insects by killing and avoiding transporting them at any living stage.

Spotted lanternflies lay eggs in masses. These masses look like light grayish-brown, mudlike or puttylike patches, typically about an inch long, and they are found on various surfaces. At any life stage the insects can be killed by squishing them, immersing them in hand sanitizer or freezing them for several days.

America has never been richer. But the gains are so lopsided that the top 10% controls 69% of all wealth in the country, while the bottom half controls just 3%. Meanwhile, surging corporate profits have mostly benefited investors, not the broader public.

This divide is expected to widen after President Donald Trump’s sweeping new spending bill drastically cuts Medicaid and food aid, programs that stabilize the economy and subsidize low-wage employers.

Moreover, the tax cuts at the heart of the bill will deliver tens of billions of dollars in benefits to the wealthiest households while disproportionately burdening low-income households, according to analyses by the nonpartisan Congressional Budget Office and Joint Committee on Taxation. By 2033, the bottom 20% will pay more in taxes while the top 0.1% receive $43 billion in cuts.

I am a sociologist who studies economic inequality, and my research demonstrates that the class-based inequalities exacerbated by the Trump bill are not new. Rather, they are part of a 50-year trend linked to social cleavages, political corruption and a declining belief in the common good.

The roots of class-based inequality

The decades following World War II were broadly prosperous, but conditions began changing in the 1970s. Class inequality has increased enormously since then, according to government data, while income inequality has risen for five decades at the expense of workers.

Economists usually gauge a country’s economic health by looking at its gross domestic product as measured through total spending on everything from groceries to patents.

But another way to view GDP is by looking at whether the money goes to workers or business owners. This second method – the income approach – offers a clearer picture of who really benefits from economic growth.

The money that goes to labor’s share of GDP, or workers, is represented by employee compensation, including wages, salaries and benefits. The money left over for businesses after paying for work and materials is called gross operating surplus, or business surplus.

The share of GDP going to workers rose 12% from 1947 to 1970, then fell 14% between 1970 and 2023. The opposite happened with the business surplus, falling 18% in the early postwar decades before jumping 34% from 1970 to today.

Meanwhile, corporate profits have outpaced economic growth by 193% since 1970. Within profits, shareholder dividends as a share of GDP grew 274%.

As of 2023, labor had lost all of the economic gains made since 1947. Had workers kept their 1970 share of GDP, they would have earned $1.7 trillion more in 2023 alone. And no legislation or federal action since 1970 has reversed this half-century trend.

When more of the economy goes to businesses instead of workers, that poses serious social problems. My research focuses on three that threaten democracy.

1. Fraying social bonds and livelihoods

Not just an issue of income and assets, growing class inequality represents the fraying of American society.

For instance, inequality and the resulting hardship are linked to worse health outcomes. Americans die younger than their peers in other rich countries, and U.S. life expectancy has decreased, especially among the poor.

Moreover, economic struggles contribute to mental health issues, deaths of despair and profound problems such as addiction, including tobacco, alcohol and opioid abuse.

Inequality can disrupt families. Kids who experience the stresses of poverty can develop neurological and emotional problems, putting them at risk for drug use as adults. On the other hand, when minimum wages increase and people begin saving wealth, divorce risk falls.

Research shows inequality has many other negative consequences, from reduced social mobility to lower social trust and even higher homicide rates.

Together, these broad social consequences are linked to misery, political discontent and normlessness.

2. Increasing corruption in politics

Inequality is rising in the U.S. largely because business elites are exercising more influence over policy outcomes, research shows. My related work on privatization explains how 50 years of outsourcing public functions – through contracting, disinvestment and job cuts – threatens democratic accountability.

Research across different countries has repeatedly found that higher income inequality increases political corruption. It does so by undermining trust in government and institutions, and enabling elites to dominate policymaking while weakening public oversight.

Since 2010, weakened campaign finance laws driven by monied interests have sharply increased corruption risks. The Supreme Court ruled then in Citizens United to lift campaign finance restrictions, enabling unlimited political spending. It reached an apex in 2024, when Elon Musk spent $200 million to elect Trump before later installing his Starlink equipment onto Federal Aviation Administration systems in a reported takeover of a $2.4 billion contract with Verizon.

Research shows that a large majority of Americans believe that the economy is rigged, suggesting everyday people sense the link between inequality and corruption.

3. Undermining belief in the common good

National aspirations have emphasized the common good since America’s founding. The Declaration of Independence lists the king’s first offense as undermining the “public good” by subverting the rule of law. The Constitution’s preamble commits the government to promoting the general welfare and shared well-being.

But higher inequality historically means the common good goes overlooked, according to research. Meanwhile, work has become more precarious, less unionized, more segmented and less geographically stable. Artificial intelligence may worsen these trends.

This tends to coincide with a drop in voting and other forms of civic engagement.

The government has fewer mechanisms for protecting community when rising inequality is paired with lower taxes for the wealthy and reduced public resources. My research finds that public sector unions especially bolster civic engagement in this environment.

Given increasing workplace and social isolation, America’s loneliness epidemic is unsurprising, especially for low earners.

All of these factors and their contribution to alienation can foster authoritarian beliefs and individualism. When people become cold and distrustful of one another, the notion of the common good collapses.

Inequality as a policy outcome

News coverage of the Trump bill and policy debate have largely centered on immediate gains and losses. But zoomed out, a clearer picture emerges of the long-term dismantling of foundations that once supported broad economic security. That, in turn, has enabled democratic decline.

As labor’s share of the economy declined, so too did the institutional trust and shared social values that underpin democratic life. Among the many consequences are the political discontent and disillusionment shaping our current moment.

Republicans hold both chambers of Congress through 2026, making significant policy changes unlikely in the short term. Democrats opposed the bill but are out of power. And their coalition is divided between a centrist establishment and an insurgent progressive wing with diverging priorities in addressing inequality.

Yet democratic decline and inequality are not inevitable. If restoring broad prosperity and social stability are the goals, they may require revisiting the New Deal-style policies that produced labor’s peak economic share of 59% of GDP in 1970.

“My dedication was questioned.”

“Managers or upper management have looked down upon taking time off.”

“People think that maybe you’re not as invested in the job, that you’re shirking your duties or something.”

These are just a few of the responses to questions I asked during a study I conducted on vacation guilt among American workers.

More than 88% of full-time, private sector workers in the U.S. receive paid time off. This benefit is ostensibly in place to improve employee morale and well-being.

Yet a 2024 Pew Research Center survey found that nearly half of American workers don’t take all the vacation days they’ve been allotted. And many of them feel as if they’re discouraged from using their time off. Ironically, what’s supposed to be a source of relaxation and restoration morphs into a stressor: As vacations approach, feelings of doubt and guilt creep in.

I’m from Singapore. Upon moving to the U.S. in 2016, I was surprised at how pervasive vacation guilt appeared to be.

Compared with many of the other countries where I’ve lived or worked, American culture seems to prioritize mental health and wellness. I assumed these attitudes extended to the American workplace.

Surprisingly, though, I noticed that many of my American friends felt guilty about taking time off that they’d earned. So as a scholar of tourism and hospitality, I wanted to understand how and why this happened.

Vacation guilt

To carry out the study, I collaborated with tourism scholar Robert Li. We interviewed 15 workers who had experienced feelings of guilt over taking time off. We also administered an online survey to 860 full-time employees who received paid time off from their employers.

We wanted to know whether employees felt less respected or believed that their bosses and colleagues saw them in a worse light for taking time off. Maybe they feared being seen as slackers or, worse, replaceable.

We found that 1 in 5 respondents to our survey experienced vacation guilt, and these concerns made them think twice about following through with their vacation plans. For those who eventually did take a vacation, they often tried to ease their guilt by going for fewer days. They might also apologize for taking a vacation or avoid talking about their vacation plans at work.

Some of the people we interviewed had pushed through their hesitation and taken their vacation as planned. Yet all of these employees believed that they’d been penalized for taking time off and that it led to poor performance reviews, despite the fact that their paid vacation days had been a clearly articulated, earned benefit.

The US is an outlier

The U.S. is the only advanced economy that doesn’t legally mandate a minimum number of vacation days. On top of that, only a handful of states require workers to be compensated for their unused vacation days.

Meanwhile, the law in other advanced economies entitles employees to a minimum amount of annual paid leave. The EU, for example, mandates at least 20 days per year on top of paid public holidays, such as Christmas and New Year’s Day, with a number of EU member countries requiring more than 20 days of paid vacation for full-time employees. Even in Japan, which is notorious for its workaholic culture, employees are entitled to a minimum of 10 days of paid leave every year.

Throughout much of the U.S., whether paid vacation time is offered at all depends on an employer’s generosity, while many employees face a “use-it-or-lose-it” situation, meaning unused vacation days don’t roll over from one year to the next.

Of course, not all workers experience vacation guilt. Nonetheless, the guilt that so many workers do feel may be symbolic of broader issues: an unhealthy workplace culture, a toxic boss or a weak social safety net.

For paid time off to serve its purpose, I think employers need to provide more than vacation days. They also need to have a supportive culture that readily encourages employees to use this benefit without having to worry about repercussions.

The number of states banning smartphones in schools is growing.

New York is now the largest state in the U.S. to ban smartphones in public schools. Starting in fall 2025, students will not be allowed to use their phones during the school day, including during lunch, recess or in between classes. This bell-to-bell policy will impact almost 2.5 million students in grades K-12.

By banning smartphones in schools, New York is joining states across the country. The bans are happening in both traditionally liberal and conservative states.

Alabama, Arkansas, Nebraska, North Dakota, Oklahoma and West Virginia all passed legislation in 2025 that requires schools to have policies that limit access to smartphones. The policies will go into effect in the 2025-2026 school year. This brings the total to 17 states, plus Washington, D.C., that have phone-free school legislation or executive orders.

I’m a professor who studies communication and culture, and while writing a book about parenting culture, I’ve noticed the narrative around smartphones and social media shifting over the past decade.

A turning tide

According to the Pew Research Center, 67% of American adults support banning smartphones during class time, although only 36% support banning them for the entire school day. Notably, a majority of Republican, Democratic and independent voters all support bans during class time.

More broadly, parent-led movements to limit children’s use of smartphones, social media and the internet have sprung up around the country. For example, the Phone-Free Schools Movement in Pennsylvania was launched in 2023, and Mothers Against Media Addiction started in New York in March 2024. These organizations, which empower parents to advocate in their local communities, follow in the footsteps of organizations such as Wait Until 8th in Texas and Screen Time Action Network at Fairplay in Massachusetts, which were formed in 2017.

The concerns of these parent-led organizations were reflected in the best-selling book “The Anxious Generation,” which paints a bleak picture of modern childhood as dominated by depression and anxiety brought on by smartphone addiction.

Phone-free schools are one of the four actions the book’s author, Jonathan Haidt, recommended to change course. The other three are no smartphones for children before high school, waiting until 16 for social media access, and allowing more childhood independence in the real world.

Haidt’s research team collaborated with The Harris Poll to survey Gen Z. They found that almost half of those age 18-27 wish social media had never been invented, and 21% wish smartphones had never been invented. About 40% of Gen Z respondents supported phone-free schools.

The Pew Research Center found that almost 40% of kids age 8-12 use social media, and almost 95% of kids age 13-17 use it, with nearly half of teens reporting that they use social media almost constantly.

Phone-free schools are also part of the larger trend of states and nations resisting Big Tech, the large technology companies that play a significant role in global commerce.

In May 2025, two U.S. senators introduced the Stop the Scroll Act, which would require mental health warnings on social media.

New laws that ban smartphones or social media for youth are being introduced across several Western nations. Australia has banned all social media for those under 16.

After a fatal stabbing at a middle school in eastern France on June 10, French President Emmanuel Macron announced the same day that he wants the European Union to set the minimum age for social media at 15. He argued that social media is a factor in teen violence. If the EU doesn’t act within a few months, Macron has pledged to enact a ban in France as soon as possible.

The impact on learning

Although this trend of restricting use of phones in school is new, more states may adopt smartphone bans in the future. Bell-to-bell bans are viewed as especially powerful in improving academic performance.

Some research has suggested that when children have access to a smartphone, even if they do not use it, they find it harder to focus in class. Initial research has found that academic performance improves after the bans go into effect.

Test scores fell across the U.S. during the pandemic lockdown and have not returned to prepandemic levels. Some states, such as Maine and Oregon, are almost a full year behind grade level in reading. Not a single state has recovered in both math and reading.

Statewide bans free local school districts from having to create their own technology bans, which can lead to heated debates. Although a majority of adults approve of banning smartphones in class, 24% oppose it for reasons such as wanting to be able to contact their kids throughout the day and wanting parents to set the boundaries.

However, 72% of high school teachers say that phones are a major distraction. Anecdotally, schools report that students like the bans after getting used to the change.

I signed the Wait Until 8th pledge mentioned in the article, promising not to give my kids a smartphone or social media until at least the end of 8th grade.
