Are people on the South Pole walking upside down from the rest of the world? – Ralph P., U.S.

When I was standing at the South Pole, I felt the same way I feel anywhere on Earth because my feet were still on the ground and the sky was still overhead.

I’m an astrophysicist from Wisconsin who lived at the South Pole for seven weeks from December 2024 to January 2025 to work on an array of detectors looking for extremely high energy particles from outer space.

I didn’t feel upside down, but there were some differences that still made the South Pole feel flipped over from what I was used to.

As someone who loves looking for the Moon, I noticed that the face of the man on the Moon was flipped over, like he went from 🙂 to 🙃. All the craters that I was used to seeing on the top of the Moon from Wisconsin were now on the bottom – because I was looking at the Moon from the Southern Hemisphere instead of the Northern Hemisphere.

After noticing this difference, I remembered something similar in the night skies of New Zealand, a country near Antarctica where my fellow travelers and I got our big red coats that kept us warm at the South Pole. I had looked for Orion, a constellation that in the Northern Hemisphere is viewed as a hunter holding a bow and drawing an arrow from his quiver. In the night sky of New Zealand, Orion looked like he was doing a handstand.

Everything in the sky felt upside down and opposite, compared with what I was used to. A person who lives in the Southern Hemisphere might feel the same about visiting the Arctic or the North Pole.

An out-of-this-world perspective

To understand what’s happening, and why things are really different but also feel very much the same, it might be useful to back up a bit from Earth’s surface. Like into outer space. On space missions to the Moon, astronauts could see one side of the Earth’s sphere at once.

If they had superhero vision, an astronaut would see the people at the South Pole and North Pole standing upside down from each other. And a person at the equator would look like they were sticking straight out the side of the planet. In fact, even though they might be standing on the equator, people in Colombia and Indonesia would also look like they were upside down from each other, because they would be sticking out from opposite sides of the Earth.

Of course, if you asked each person, they would say, “My feet are on the ground, and the sky is up.”

That’s because Earth is essentially a really big ball whose gravitational pull on every one of us points to the center of the planet. The direction that Earth pulls us in is what people call “down” all over the planet. Think about holding a baseball between your pointer fingers. From the perspective of your fingertips on the ball’s surface, both are pointing “down.” But from the perspective of a friend nearby, your fingers are pointing in different directions – though always toward the center of the ball.

These relationships between people on the Earth’s surface are good for a little bit of fun, though. While I was at the South Pole, I pointed my body in the same direction as my friends in Wisconsin – by doing a handstand. But if you look at the picture the other way around, it looks like I’m holding up the entire planet, like Superman.

Cape Town’s sewage treatment isn’t coping: scientists are worried about what the city is telling the public

Source: The Conversation – Africa – By Lesley Green, Professor of Earth Politics and Director: Environmental Humanities South, University of Cape Town

Urban water bodies – rivers, lakes and oceans – are in trouble globally. Large sewage volumes damage the open environment, and new chemicals and pharmaceutical compounds don’t break down on their own. When they are released into the open environment, they build up in living tissues all along the food chain, bringing with them multiple health risks.

The city of Cape Town, South Africa, is no exception. It has 300km of coastline along two bays and a peninsula, as well as multiple rivers and wetlands. The city discharges more than 40 megalitres of raw sewage directly into the Atlantic Ocean every day. In addition, large volumes of poorly treated sewage and runoff from shack settlements enter rivers and from there into both the Atlantic and the Indian Oceans.

Over almost a decade, our multi-disciplinary team, and others, have studied contamination risks in Cape Town’s oceans, rivers, aquifers and lakes. Our goal has been to bring evidence of contaminants to the attention of officials responsible for a clean environment.

Monitoring sewage levels in the city’s water bodies is essential because of the health risks posed by contaminated water to all citizens – farmers, surfers, and everybody eating fish and vegetables. Monitoring needs to be done scientifically and in a way that produces data that is trustworthy and not driven by vested interests. This is a challenge in cities where scientific findings are expected to support marketing of tourism or excellence of the political administration.

Our research findings have been published in multiple peer-reviewed journals. We have also communicated with the public through articles in the media, a website and a documentary.

Cape Town’s official municipal responses to independent studies and reports, however, have been hostile. Our work has been unjustifiably denounced by top city officials and politicians. We have been subject to attacks by fake social media avatars. Laboratory studies have even received a demand for an apology from the political party in charge of the city.

These extraordinary responses – and many others – reflect the extent to which independent scientific inquiry has been under attack.

We set about tracking the different kinds of denial and attacks on independent contaminant science in Cape Town over 11 years. Our recently published study describes 18 different types of science communication that have minimised or denied the problem of contamination. It builds on similar studies elsewhere.

Our findings show the extent to which contaminant science in Cape Town is at risk of producing not public knowledge but public ignorance, reflecting similar patterns internationally where science communication sometimes obfuscates more than it informs. To address this risk, we argue that institutionalised conflicts of interest should be removed. There should also be changes to how city-funded testing is done and when data is released to citizens. After all, it is citizens’ rates and taxes that have paid for that testing, and the South African constitution guarantees the right to information.

We also propose that the city’s political leaders take the courageous step of accepting that the current water treatment infrastructure is unworkable for a city of over 5 million people. Accepting this would open the door to an overhaul of the city’s approach to wastewater treatment.

The way forward

We divided our study of contaminant communication events into four sub-categories:

non-disclosure of data
misinformation that gives a partial or misleading account of a scientific finding
using city-funded science to bolster political authority
relying on point data collected fortnightly to prove “the truth” of bodies of water as if it never moves or changes, when in reality, water bodies move every second of every day.

We found evidence of multiple instances of miscommunication. On the basis of these, we make specific recommendations.

First: municipalities should address conflicts of interest that are built into their organisational structure. These arise when the people responsible for ensuring that water bodies are healthy are simultaneously contracting consultants to conduct research on water contaminants. This is particularly important because over the last two decades large consultancies have established themselves as providers of scientific certification. But they are profit-making ventures, which calls into question the independence of their findings.

Second: the issue of data release needs to be addressed. Two particular problems stand out:

Real-time information. Water quality results for beaches are usually released a week or more after samples have been taken. But because water moves all the time every day, people living in the city need real-time information. Best-practice water contamination measures use water current models to predict where contaminated water will be, given each day’s different winds and temperatures.
Poor and incomplete data. When ocean contaminant data is released as a 12-month rolling average, all the very high values are smoothed out. The end result is a figure that does not communicate the reality of risks under different conditions.

Third: Politicians should be accountable for their public statements on science. Independent and authoritative scientific bodies, such as the Academy of Science of South Africa, should be empowered to audit municipal science communications.

Fourth: Reputational harm to the science community must stop. Government officials claiming that they alone know a scientific truth and denouncing independent scientists with other data closes down the culture of scientific inquiry. And it silences others.

Fifth: The integrity of scientific findings needs to be protected. Many cities, including Cape Town, rely on corporate brand management and political reputation management. Nevertheless, cities, by their very nature, have to deal with sewage, wastes and runoff. Public science communication that is based on marketing strategies prioritises advancing a brand (whether of a political party or a tourist destination). The risk is that city-funded science is turned into advertising and is presented as unquestionable.

Finally, Cape Town needs political leaders who are courageous enough to confront two evident realities. Current science communications in the city are not serving the public well, and wastewater treatment systems that use rivers and oceans as open sewers are a solution designed a century ago. Both urgently need to be reconfigured.

Next steps

As a team of independent contaminant researchers we have worked alongside communities where health, ecology, livestock and recreation have been profoundly harmed by ongoing contamination. We have documented these effects, only to hear the evidence denied by officials.

We recognise and value the beginnings of some new steps to data transparency in Cape Town’s mayoral office, like rescinding the 2021 by-law that banned independent scientific testing of open water bodies, almost all of which are classified as nature reserves.

We would welcome a dialogue on building strong and credible public science communications.

This study is dedicated to the memory of Mpharu Hloyi, head of Scientific Services in the City of Cape Town, in acknowledgement of her dedication to the health of urban bodies of water. Her untimely passing was a loss for all.

Astronomers have spied an interstellar object zooming through the Solar System

Source: The Conversation – Global Perspectives – By Kirsten Banks, Lecturer, School of Science, Computing and Engineering Technologies, Swinburne University of Technology

This week, astronomers spotted the third known interstellar visitor to our Solar System.

First detected by the Asteroid Terrestrial-impact Last Alert System (ATLAS) on July 1, the cosmic interloper was given the temporary name A11pl3Z. Experts at NASA’s Center for Near Earth Object Studies and the International Astronomical Union (IAU) have confirmed the find, and the object now has an official designation: 3I/ATLAS.

There are a few strong clues that suggest 3I/ATLAS came from outside the Solar System.

First, it’s moving really fast. Current observations show it speeding through space at around 245,000km per hour. That’s more than enough to escape the Sun’s gravity.

An object near Earth’s orbit would only need to be travelling at just over 150,000km/h to break free from the Solar System.

Second, 3I/ATLAS has a wildly eccentric orbit around the Sun. Eccentricity measures how “stretched” an orbit is: 0 eccentricity is a perfect circle, and anything up to 1 is an increasingly strung-out ellipse. Above 1 is an orbit that is not bound to the Sun.

3I/ATLAS has an estimated eccentricity of 6.3, by far the highest ever recorded for any object in the Solar System.

Has anything like this happened before?

The first interstellar object spotted in our Solar System was the cigar-shaped ‘Oumuamua, discovered in 2017 by the Pan-STARRS1 telescope in Hawaii. Scientists tracked it for 80 days before eventually confirming it came from interstellar space.

The second interstellar visitor, comet 2I/Borisov, was discovered two years later by amateur astronomer Gennadiy Borisov. This time it only took astronomers a few weeks to confirm it came from outside the Solar System.

This time, the interstellar origin of 3I/ATLAS has been confirmed in a matter of days.

How did it get here?

We have only ever seen three interstellar visitors (including 3I/ATLAS), so it’s hard to know exactly how they made their way here.

However, recent research published in The Planetary Science Journal suggests these objects might be more common than we once thought. In particular, they may come from relatively nearby star systems such as Alpha Centauri (our nearest interstellar neighbour, a mere 4.4 light years away).

Alpha Centauri is slowly moving closer to us, with its closest approach expected in about 28,000 years. If it flings out material in the same way our Solar System does, scientists estimate around a million objects from Alpha Centauri larger than 100 metres in diameter could already be in the outer reaches of our Solar System. That number could increase tenfold as Alpha Centauri gets closer.

Most of this material would have been ejected at relatively low speeds, less than 2km/s, making it more likely to drift into our cosmic neighbourhood over time and not dramatically zoom in and out of the Solar System like 3I/ATLAS appears to be doing. While the chance of one of these objects coming close to the Sun is extremely small, the study suggests a few tiny meteors from Alpha Centauri, likely no bigger than grains of sand, may already hit Earth’s atmosphere every year.

Why is this interesting?

Discovering new interstellar visitors like 3I/ATLAS is thrilling, not just because they’re rare, but because each one offers a unique glimpse into the wider galaxy. Every confirmed interstellar object expands our catalogue and helps scientists better understand the nature of these visitors, how they travel through space, and where they might have come from.

Thanks to powerful new observatories such as the NSF–DOE Vera C. Rubin Observatory, our ability to detect these elusive objects is rapidly improving. In fact, during its first 10 hours of test imaging, Rubin revealed 2,104 previously unknown asteroids.

This is an astonishing preview of what’s to come. With its wide field of view and constant sky coverage, Rubin is expected to revolutionise our search for interstellar objects, potentially turning rare discoveries into routine ones.

What now?

There’s still plenty left to uncover about 3I/ATLAS. Right now, it’s officially classified as a comet by the IAU Minor Planet Center.

But some scientists argue it might actually be an asteroid, roughly 20km across, based on the lack of typical comet-like features such as a glowing coma or a tail. More observations will be needed to confirm its nature.

Currently, 3I/ATLAS is inbound, just inside Jupiter’s orbit. It’s expected to reach its closest point to the Sun, slightly closer than the planet Mars, on October 29. After that, it will swing back out towards deep space, making its closest approach to Earth in December. (It will pose no threat to our planet.)

Whether it’s a comet or an asteroid, 3I/ATLAS is a messenger from another star system. For now, these sightings are rare – though as next-generation observatories such as Rubin swing into operation, we may discover interstellar companions all around.

We don’t need deep-sea mining, or its environmental harms. Here’s why

Deep-sea mining promises critical minerals for the energy transition without the problems of mining on land. It also promises to bring wealth to developing nations. But the evidence suggests these promises are false, and mining would harm the environment.

The practice involves scooping up rock-like nodules from vast areas of the sea floor. These potato-sized lumps contain metals and minerals such as zinc, manganese, molybdenum, nickel and rare earth elements.

Technology to mine the deep sea exists, but commercial mining of the deep sea is not happening anywhere in the world. That could soon change. Nations are meeting this month in Kingston, Jamaica, to agree to a mining code. Such a code would make way for mining to begin within the next few years.

On Thursday, Australia’s national science agency, CSIRO, released research into the environmental impacts of deep-sea mining. It aims to promote better environmental management of deep-sea mining, should it proceed.

We have previously challenged the rationale for deep-sea mining, drawing on our expertise in international politics and environmental management. We argue mining the deep sea is harmful and the economic benefits have been overstated. What’s more, the metals and minerals to be mined are not scarce.

The best course of action is a ban on international seabed mining, building on the coalition for a moratorium.

The Metals Company spent six months at sea collecting nodules in 2022, while studying the effects on ecosystems.

Managing and monitoring environmental harm

Recent advances in technology have made deep-sea mining more feasible. But removing the nodules – which also requires pumping water around – has been shown to damage the seabed and endanger marine life.

CSIRO has developed the first environmental management and monitoring frameworks to protect deep sea ecosystems from mining. It aims to provide “trusted, science-based tools to evaluate the environmental risks and viability of deep-sea mining”.

Scientists from Griffith University, Museums Victoria, the University of the Sunshine Coast, and Earth Sciences New Zealand were also involved in the work.

The Metals Company Australia, a local subsidiary of the Canadian deep-sea mining exploration company, commissioned the research. It involved analysing data from test mining the company carried out in the Pacific Ocean in 2022.

The company has led efforts to expedite deep-sea mining. This includes pushing for the mining code, and exploring commercial mining of the international seabed through approval from the US government.

In a media briefing this week, CSIRO Senior Principal Research Scientist Piers Dunstan said the mining activity substantially affected the sea floor. Some marine life, especially that attached to the nodules, had very little hope of recovery. He said if mining were to go ahead, monitoring would be crucial.

We are sceptical that ecological impacts can be managed even with this new framework. Little is known about life in these deep-water ecosystems. But research shows nodule mining would cause extensive habitat loss and damage.

Do we really need to open the ocean frontier to mining? We argue the answer is no, on three counts.

How does deep-sea mining work? (The Guardian)

1. Minerals are not scarce

The minerals required for the energy transition are abundant on land. Known global terrestrial reserves of cobalt, copper, manganese, molybdenum and nickel are enough to meet current production levels for decades – even with growing demand.

There is no compelling reason to extract deep-sea minerals, given the economics of both deep-sea and land-based mining. Deep-sea mining is speculative and inevitably too expensive given such remote, deep operations.

Claims about mineral scarcity are being used to justify attempting to legitimise a new extractive frontier in the deep sea. Opportunistic investors can make money through speculation and attracting government subsidies.

2. Mining at sea will not replace mining on land

Proponents claim deep-sea mining can replace some mining on land. Mining on land has led to social issues including infringing on indigenous and community rights. It also damages the environment.

But deep-sea mining will not necessarily displace, replace or change mining on land. Land-based mining contracts span decades and the companies involved will not abandon ongoing or planned projects. Their activities will continue, even if deep-sea mining begins.

Deep-sea mining also faces many of the same challenges as mining on land, while introducing new problems. The social problems that arise during transport, processing and distribution remain the same.

And sea-based industries are already rife with modern slavery and labour violations, partly because they are notoriously difficult to monitor.

Deep-sea mining does not solve social problems with land-based mining, and adds more challenges.

3. Common heritage of humankind and the Global South

Under the United Nations Convention on the Law of the Sea, the international seabed is the common heritage of humankind. This means the proceeds of deep-sea mining should be distributed fairly among all countries.

Deep-sea mining commercial partnerships between developing countries in the Global South and firms from the North have yet to pay off for the former. There is little indication this pattern will change.

For example, when Canadian company Nautilus went bankrupt in 2019, it saddled Papua New Guinea with millions in debt from a failed domestic deep-sea mining venture.

The Metals Company has partnerships with Nauru and Tonga but the latest deal with the US creates uncertainty about whether their agreements will be honoured.

European investors took control of Blue Minerals Jamaica, originally a Jamaican-owned company, shortly after orchestrating its start up. Any profits would therefore go offshore.

A wise investment?

It is unclear whether deep-sea mining will ever be a good investment.

Multiple large corporate investors have pulled out of the industry, or gone bankrupt. And The Metals Company has received delisting notices from the Nasdaq stock exchange due to poor financial performance.

Given the threat of environmental harm, the evidence suggests deep-sea mining is not worth the risk.

Ageing bridges around the world are at risk of collapse. But there’s a simple way to safeguard them

Source: The Conversation – Global Perspectives – By Andy Nguyen, Senior Lecturer in Structural Engineering, University of Southern Queensland

The Story Bridge, with its sweeping steel trusses and art deco towers, is a striking sight above the Brisbane River in Queensland. In 2025, it was named the state’s best landmark. But more than an icon, it serves as one of the vital arteries of the state capital, carrying more than 100,000 vehicles daily.

But a recent report revealed serious structural issues in the 85-year-old bridge. These included the deterioration of concrete, corrosion and overloading on pedestrian footpaths.

The findings prompted an urgent closure of the footpath for safety reasons. They also highlighted the urgency of Brisbane City Council’s planned bridge restoration project.

But this example – and far more tragic ones from around the world in recent years – have also sparked a broader conversation about the safety of ageing bridges and other urban infrastructure. A simple, proactive step known as structural health monitoring can help.

A number of collapses

In January 2022, the Fern Hollow Bridge in Pittsburgh, Pennsylvania, in the United States collapsed and injured several people. This collapse was caused by extensive corrosion and the fracturing of a vital steel component. It stemmed from poor maintenance and failure to act on repeated inspection recommendations. These problems were compounded by inadequate inspections and oversight.

Three years earlier, Taiwan’s Nanfang’ao Bridge collapsed. Exposure to damp, salty sea air had severely weakened its suspension cables. Six people beneath the bridge died.

In August 2018, Italy’s Morandi Bridge fell, killing 43 people. The collapse was due to corrosion in pre-stressed concrete and steel tendons. These factors were worsened by inspection and maintenance challenges.

In August 2007, a bridge in the US city of Minneapolis collapsed, killing 13 people and injuring 145. This collapse was primarily due to previously unnoticed problems with the design of the bridge. But it also demonstrated how ageing infrastructure, coupled with increasing loads and ineffective routine visual inspections, can exacerbate inherent weaknesses.

A technology-driven solution

Structural health monitoring is a technology-driven approach to assessing the condition of infrastructure. It can provide near real-time information and enable timely decision-making. This is crucial when it comes to managing ageing structures.

The approach doesn’t rely solely on occasional periodic inspections. Instead it uses sensors, data loggers and analytics platforms to continuously monitor stress, vibration, displacement, temperature and corrosion on critical components.

This approach can significantly improve our understanding of bridge performance compared to traditional assessment models. In one case, it updated a bridge’s estimated fatigue life – the remaining life of the structure before fatigue-induced failure is predicted to occur– from just five years to more than 52 years. This ultimately avoided unnecessary and costly restoration.

Good structural health-monitoring systems can last several decades. They can be integrated with artificial intelligence techniques and bridge information modelling to develop digital twin-based monitoring platforms.

The cost of structural health monitoring systems varies by bridge size and the extent of monitoring required. Some simple systems can cost just a few thousand dollars, while more advanced ones can cost more than A$300,000.

These systems require ongoing operational support – typically 10% to 20% of the installation cost annually – for data management, system maintenance, and informed decision-making.

Additionally, while advanced systems can be costly, scalable structural health monitoring solutions allow authorities to start small and expand over time.

A model for proactive management

The design of structural health monitoring systems has been incorporated into new large-scale bridge designs, such as Sutong Bridge in China and Governor Mario M. Cuomo Bridge in the US.

But perhaps the most compelling example of these systems in action is the Jacques Cartier Bridge in Montreal, Canada.

Opened in 1930, it shares design similarities with Brisbane’s Story Bridge. And, like many ageing structures, it faces its own challenges.

However, authorities managing the Jacques Cartier Bridge have embraced a proactive approach through comprehensive structural health monitoring systems. The bridge has been outfitted with more than 300 sensors.

Acoustic emission monitoring enables early detection of micro-cracking activity, while long-term instrumentation tracks structural deformation and dynamic behaviour across key spans.

Satellite-based radar imagery adds a remote, non-intrusive layer of deformation monitoring, and advanced data analysis ensures that the vast amounts of sensor data are translated into timely, actionable insights.

Together, these technologies demonstrate how a well-integrated structural-health monitoring system can support proactive maintenance, extend the life of ageing infrastructure – and ultimately improve public safety.

A way forward for Brisbane – and beyond

The Story Bridge’s current challenges are serious, but they also present an opportunity.

By investing in the right structural health monitoring system, Brisbane can lead the way in modern infrastructure management – protecting lives, restoring public confidence, preserving heritage and setting a precedent for cities around the world.

As climate change, urban growth, and ageing assets put increasing pressure on our transport networks, smart monitoring is no longer a luxury – it’s a necessity.

Rural hospitals will be hit hard by Trump’s signature spending package

Health policy experts predict that cuts to Medicaid will push more rural hospitals to close. sneakpeekpic via iStock / Getty Images Plus

The public health provisions in the massive spending package that President Donald Trump signed into law on July 4, 2025, will reduce Medicaid spending by more than US$1 trillion over a decade and result in an estimated 11.8 million people losing health insurance coverage.

As researchers studying rural health and health policy, we anticipate that these reductions in Medicaid spending, along with changes to the Affordable Care Act, will disproportionately affect the 66 million people living in rural America – nearly 1 in 5 Americans.

People who live in rural areas are more likely to have health insurance through Medicaid and are at greater risk of losing that coverage. We expect that the changes brought about by this new law will lead to a rise in unpaid care that hospitals will have to provide. As a result, small, local hospitals will have to make tough decisions that include changing or eliminating services, laying off staff and delaying the purchase of new equipment. Many rural hospitals will have to reduce their services or possibly close their doors altogether.

Hits to rural health

The budget legislation’s biggest effect on rural America comes from changes to the Medicaid program, which represent the largest federal rollback of health insurance coverage in the U.S. to date.

First, the legislation changes how states can finance their share of the Medicaid program by restricting where funds states use to support their Medicaid programs can come from. This bill limits how states can tax and charge fees to hospitals, managed care organizations and other health care providers, and how they can use such taxes and fees in the future to pay higher rates to providers under Medicaid. These limitations will reduce payments to rural hospitals that depend upon Medicaid to keep their doors open.

Rural hospitals play a crucial role in health care access.

Second, by 2027, states must institute work requirements that demand most Medicaid enrollees work 80 hours per month or be in school at least half time. Arkansas’ brief experiment with work requirements in 2018 demonstrates that rather than boost employment, the policy increases bureaucracy, hindering access to health care benefits for eligible people. States will also now be required to verify Medicaid eligibility every six months versus annually. That change also increases the risk people will lose coverage due to extra red tape.

The Congressional Budget Office estimates that work requirements instituted through this legislative package will result in nearly 5 million people losing Medicaid coverage. This will decrease the number of paying patients at rural hospitals and increase the unpaid care hospitals must provide, further damaging their ability to stay open.

Additionally, the bill changes how people qualify for the premium tax credits within the Affordable Care Act Marketplace. The Congressional Budget Office estimates that this change, along with other changes to the ACA such as fewer and shorter enrollment periods and additional requirements for documenting income, will reduce the number of people insured through the ACA Marketplace by about 3 million by 2034. Premium tax credits were expanded during the COVID-19 pandemic, helping millions of Americans obtain coverage who previously struggled to do so. This bill lets these expanded tax credits expire, which with may result in an additional 4.2 million people becoming uninsured.

An insufficient stop-gap

Senators from both sides of the aisle have voiced concerns about the legislative package’s potential effects on the financial stability of rural hospitals and frontier hospitals, which are facilities located in remote areas with fewer than six people per square mile. As a result, the Senate voted to set aside $50 billion over the next five years for a newly created Rural Health Transformation Program.

These funds are to be allocated in two ways. Half will be directly distributed equally to states that submit an application that includes a rural health transformation plan detailing how rural hospitals will improve the delivery and quality of health care. The remainder will be distributed to states in varying amounts through a process that is currently unknown.

While additional funding to support rural health facilities is welcome, how it is distributed and how much is available will be critical. Estimates suggest that rural areas will see a reduction of $155 billion in federal spending over 10 years, with much of that concentrated in 12 states that expanded Medicaid under the Affordable Care Act and have large proportions of rural residents.

That means $50 billion is not enough to offset cuts to Medicaid and other programs that will reduce funds flowing to rural health facilities.

Accelerating hospital closures

Rural and frontier hospitals have long faced hardship because of their aging infrastructure, older and sicker patient populations, geographic isolation and greater financial and regulatory burdens. Since 2010, 153 rural hospitals have closed their doors permanently or ceased providing inpatient services. This trend is particularly acute in states that have chosen not to expand Medicaid via the Affordable Care Act, many of which have larger percentages of their residents living in rural areas.

According to an analysis by University of North Carolina researchers, as of June 2025 338 hospitals are at risk of reducing vital services, such as skilled nursing facilities; converting to an alternative type of health care facility, such as a rural emergency hospital; or closing altogether.

Maternity care is especially at risk.

Currently more than half of rural hospitals no longer deliver babies. Rural facilities serve fewer patients than those in more densely populated areas. They also have high fixed costs, and because they serve a high percentage of Medicaid patients, they rely on payments from Medicaid, which tends to pay lower rates than commercial insurance. Because of these pressures, these units will continue to close, forcing women to travel farther to give birth, to deliver before going full term and to deliver outside of traditional hospital settings.

And because hospitals in rural areas serve relatively small populations, they lack negotiating power to obtain fair and adequate payment from private health insurers and affordable equipment and supplies from medical companies. Recruiting and retaining needed physicians and other health care workers is expensive, and acquiring capital to renovate, expand or build new facilities is increasingly out of reach.

Finally, given that rural residents are more likely to have Medicaid than their urban counterparts, the legislation’s cuts to Medicaid will disproportionately reduce the rate at which rural providers and health facilities are paid by Medicaid for services they offer. With many rural hospitals already teetering on closure, this will place already financially fragile hospitals on an accelerated path toward demise.

Far-reaching effects

Rural hospitals are not just sources of local health care. They are also vital economic engines.

Hospital closures result in the loss of local access to health care, causing residents to choose between traveling longer distances to see a doctor or forgoing the services they need.

But hospitals in these regions are also major employers that often pay some of the highest wages in their communities. Their closure can drive a decline in the local tax base, limiting funding available for services such as roads and public schools and making it more difficult to attract and retain businesses that small towns depend on. Declines in rural health care undermine local economies.

Furthermore, the country as a whole relies on rural America for the production of food, fuel and other natural resources. In our view, further weakening rural hospitals may affect not just local economies but the health of the whole U.S. economy.

The oldest rocks on Earth are more than four billion years old

Source: The Conversation – Canada – By Hanika Rizo, Associate Professor, Department of Earth Sciences, Carleton University

Earth formed about 4.6 billion years ago, during the geological eon known as the Hadean. The name “Hadean” comes from the Greek god of the underworld, reflecting the extreme heat that likely characterized the planet at the time.

By 4.35 billion years ago, the Earth might have cooled down enough for the first crust to form and life to emerge.

However, very little is known about this early chapter in Earth’s history, as rocks and minerals from that time are extremely rare. This lack of preserved geological records makes it difficult to reconstruct what the Earth looked like during the Hadean Eon, leaving many questions about its earliest evolution unanswered.

We are part of a research team that has confirmed the oldest known rocks on Earth are located in northern Québec. Dating back more than four billion years, these rocks provide a rare and invaluable glimpse into the origins of our planet.

Remains from the Hadean Eon

The Hadean Eon is the first period in the geological timescale, spanning from Earth’s formation 4.6 billion years ago and ending around 4.03 billion years ago.

The oldest terrestrial materials ever dated by scientists are extremely rare zircon minerals that were discovered in western Australia. These zircons were formed as early as 4.4 billion years ago, and while their host rock eroded away, the durability of zircons allowed them to be preserved for a long time.

Studies of these zircon minerals has given us clues about the Hadean environment, and the formation and evolution of Earth’s oldest crust. The zircons’ chemistry suggests that they formed in magmas produced by the melting of sediments deposited at the bottom of an ancient ocean. This suggests that the zircons are evidence that the Hadean Eon cooled rapidly, and liquid water oceans were formed early on.

Other research on the Hadean zircons suggests that the Earth’s earliest crust was mafic (rich in magnesium and iron). Until recently, however, the existence of that crust remained to be confirmed.

In 2008, a study led by one of us — associate professor Jonathan O’Neil (then a McGill University doctoral student) — proposed that rocks of this ancient crust had been preserved in northern Québec and were the only known vestige of the Hadean.

Since then, the age of those rocks — found in the Nuvvuagittuq Greenstone Belt — has been controversial and the subject of ongoing scientific debate.

‘Big, old solid rock’

The Nuvvuagittuq Greenstone Belt is located in the northernmost region of Québec, in the Nunavik region above the 55th parallel. Most of the rocks there are metamorphosed volcanic rocks, rich in magnesium and iron. The most common rocks in the belt are called the Ujaraaluk rocks, meaning “big old solid rock” in Inuktitut.

The age of 4.3 billion years was proposed after variations in neodymium-142 were detected, an isotope produced exclusively during the Hadean through the radioactive decay of samarium-146. The relationship between samarium and neodymium isotope abundances had been previously used to date meteorites and lunar rocks, but before 2008 had never been applied to Earth rocks.

This interpretation, however, was challenged by several research groups, some of whom studied zircons within the belt and proposed a younger age of at most 3.78 billion years, placing the rocks in the Archean Eon instead.

Confirming the Hadean Age

In the summer of 2017, we returned to the Nuvvuagittuq belt to take a closer look at the ancient rocks. This time, we collected intrusive rocks — called metagabbros — that cut across the Ujaraaluk rock formation, hoping to obtain independent age constraints. The fact that these newly studied metagabbros are in intrusion in the Ujaraaluk rocks implies that the latter must be older.

The project was led by masters student Chris Sole at the University of Ottawa, who joined us in the field. Back in the laboratory, we collaborated with French geochronologist Jean-Louis Paquette. Additionally, two undergraduate students — David Benn (University of Ottawa) and Joeli Plakholm (Carleton University) participated to the project.

We combined our field observations with petrology, geochemistry, geochronology and applied two independent samarium-neodymium age dating methods, dating techniques used to assess the absolute ages of magmatic rocks, before they became metamorphic rocks. Both assessments yielded the same result: the intrusive rocks are 4.16 billion years old.

The oldest rocks

Since these metagabbros cut across the Ujaraaluk formation, the Ujaraaluk rocks must be even older, placing them firmly in the Hadean Eon.

Studying the Nuvvuagittuq rocks, the only preserved rocks from the Hadean, provides a unique opportunity to learn about the earliest history of our planet. They can help us understand how the first continents formed, and how and when Earth’s environment evolved to become habitable.

University leaders have to make sense of massive disruption — 4 ways they do it

Source: The Conversation – Canada – By Daniel Atlin, Adjunct Professor, Gordon S. Lang School of Business, University of Guelph

Trying to navigate an environment where massive disruption and unprecedented change is the norm presents a challenge for business leaders everywhere.

Social-purpose, multi-stakeholder organizations like post-secondary institutions, hospitals, governments and NGOs are particularly affected.

The practice of “sense-making” — making sense of the situations people find themselves in, in the words of organizational theorist Karl Weick — offers an innovative and timely framework that can help social-purpose leaders address complexity.

Senior post-secondary leaders study

Management experts have described sense-making as the key skill needed in an age of disruption. This has been confirmed through my research while completing a master’s degree in change leadership.

I interviewed more than two dozen senior leaders in complex organizations in Canada, the United Kingdom, Australia and New Zealand — the majority of whom were in the post-secondary sector. I found the leaders I interviewed were intuitively using elements from Weick’s organizational sense-making framework.

As one leader shared:

“The first thing you need to do is to recognize that it’s your role to help the rest of your community make sense of what’s happening around you. It’s something that I take very seriously.”

Deborah Ancona, professor of management at MIT, says:

“Sense-making is most often needed when our understanding of the world becomes unintelligible in some way. This occurs when the environment is changing rapidly, presenting us with surprises for which we are unprepared or confronting us with adaptive, rather than technical problems to solve.”

Leading in ‘age of outrage’

Social-purpose organizations face common issues such as a lack of funding, system fragmentation, competing stakeholders, new entrants and the challenges of emerging technologies.

They are also at the centre of what business and public policy professor Karthik Ramana describes as “the age of outrage,” reflected in heightened polarization. Against this backdrop, it’s increasingly challenging to attract and retain leaders.

I heard from leaders who felt they didn’t have the proper training for the job or support once they started their roles. In part, this is because few of them, including those involved in their hiring, seem to realize the actual messiness inherent within their organizations.

This brings to mind the parable that writer David Foster Wallace used in his 2005 convocation speech at Kenyon College, in which two young fish are told by an older fish that they are swimming in water. One of the young fish then turns to the other in surprise and says: “What is water anyway?”

Lack of agency

I heard from various leaders who experienced an “aha” moment when they realized they were immersed within a fluid and dynamic organizational environment that they were expected to run like a traditional business. This realization gave them a framework to understand the lack of agency they often experienced.

The challenge with social-purpose organizations is that they’re complex adaptive systems in which individual interactions form an ever-changing array of networks generating emergent behaviours that are often unpredictable. Complex adaptive systems also tend to revert to the status quo when faced with change.

So how do social-purpose leaders navigate change and this challenging organizational context? They wrap their efforts around purpose. It’s an anchor point and unifying focus for leaders, teams and all stakeholders.

4 strategies

Based on my research, I’ve identified four main sense-making strategies that leaders use:

Exploration and map-making: These pursuits help leaders extract a steady flow of information and data from their interactions both inside and outside their organizations. This allows them to develop high-level, adaptive frameworks that are constantly in flux — similar to Google Maps, as it generates live snapshots of traffic flows and suggested routes.

Storytelling and narrative development: Leaders use storytelling and narrative development to project ideas, purposes and visions into the future. This allows them to connect emotionally and inspire people and communities. Recognizing their role as storyteller-in-chief can align disparate parts of an organization into a coherent and engaged whole.

Invention and improvisation: These are employed by leaders to test assumptions as they learn what works and what doesn’t. This approach allows them to respond in real time to the never-ending flow of new information. Without taking risks, leaders are at risk of being stuck in paralysis.

Adaptation and collaboration allows leaders to help their organizations remain relevant. Leaders spoke about the need to foster adaptation. They also stressed the need to attract new resources through collaboration across like-minded institutions, governments, funding partners and the private sector.

Embracing a sense-making mindset

Thinking that benefits the interests and perspectives of the total enterprise is a critical but challenging task for leaders in social- purpose organizations.

Time and energy — two scarce resources — are necessary to build aligned and high-performing teams and to break down silos. Team alignment cannot be achieved through the occasional team-building session, but requires an ongoing commitment and a well-articulated plan.

Social-purpose organizations need practices, frameworks and metrics that are tailored to organizations’ unique needs. Rather than spending resources, time and energy on strategic plans, some leaders are building more flexible strategic frameworks or using strategic foresight to guide an innovative vision for the future.

Leadership can be lonely

It’s also important to remember that leadership can be lonely. To survive and thrive, social-purpose leaders must remember to seek out their own coaches and build communities of practice to enhance their lived experience and activities.

Developing an outer shell to weather criticism also helps. While leaders can’t please everyone, sense-making leaders find strength and build endurance in the recognition that the roles they play are meaningful, satisfying and essential — not only within the organizations they serve but through the collective work their organizations accomplish in the world.

Leaders (and board members) must realize that hiring the same people with the same profile as the past won’t make an organization ready for change, but instead reinforces the status quo.

By recognizing the messiness of their organizations and using sense-making skills, leaders in social-purpose organizations have better odds of surviving the perils and challenges of massive disruption and unprecedented change.

Workplaces have embraced mindfulness and self-compassion — but did capitalism hijack their true purpose?

Mindfulness and self-compassion have become popular tools for improving mental health and well-being in the workplace. Mindfulness involves paying attention to thoughts, emotions and surroundings without judgment, much like watching clouds pass in the sky. This moment-to-moment awareness helps people respond skilfully rather than react automatically.

Self-compassion builds on mindfulness by encouraging people to meet difficult feelings and experiences with kindness instead of resistance. In other words, mindfulness helps people first recognize their suffering, while self-compassion helps people respond with kindness.

Both mindfulness and self-compassion can be practised formally through meditations like body scans, breath awareness or loving-kindness meditation, and informally by bringing mindful attention to mind, emotions and everyday activities.

Both practices have the potential to transform dysfunctional workplaces by improving the collective well-being and personal agency of employees.

Yet too often, these practices are introduced superficially to boost productivity and performance, rather than used to address the root causes of workplace stress. It’s a pattern I’ve witnessed repeatedly in my years as a mindfulness teacher and researcher.

This brings into question whether these practices can thrive in capitalist systems that prioritize profit over people. But rather than rejecting mindfulness and self-compassion as incompatible with capitalism, I argue we need a more thoughtful framework that stays true to their essence while tackling common misunderstandings and misuses.

How capitalism is co-opting mindfulness

Academic and practitioner critics have raised concerns about how mindfulness and self-compassion practices are being integrated into corporate life.

Some of these critics argue that companies are incorporating mindfulness and self-compassion practices not to fix systemic problems, but to boost their own productivity and shift the responsibility for stress onto employees.

In these cases, critics use the term “McMindfulness” to describe a commodified, diluted version of mindfulness that is stripped of its roots in Buddhist philosophy.

Some critics have gone further, claiming that mindfulness encourages contentment with the status quo and may make employees more vulnerable to exploitation.

While these critiques raise valid concerns, they often create more confusion and resistance than meaningful dialogue or practical solutions for implementing mindfulness and self-compassion in the workplace.

Empirical research offers a more nuanced perspective. Mindfulness and self-compassion, when practised consistently, can strengthen employees’ sense of agency, improve their self-confidence, support ethical decision-making and action for meaningful change.

Done right, mindfulness can help workers

Employees who develop mindfulness and self-compassion skills tend to respond in three main ways, according to research.

First, they become more aware of dysfunction in the workplace. This awareness can empower them to speak up and advocate for change if it’s within their control and in their own interest. It can also cause them to engage in more ethical practices, especially in toxic work environments.

Second, they are more likely to leave toxic work environments. When employees realize change is beyond their control, mindfulness and self-compassion can cause them to lose their motivation for work and, indirectly, might prompt them to leave toxic workplaces altogether.

Third, for employees who end up staying in their roles, they are better able to acknowledge and become less effected by stressors. However, this doesn’t mean they become more productive or blindly enthusiastic about their jobs. Mindfulness enhances motivation that stems from genuine interest, not from pressure or obligation.

It’s important to note that mindfulness doesn’t mean these employees condone poor conditions or toxic practices. Rather, it helps them see reality more clearly, without denial or avoidance.

And for employers hoping mindfulness will instantly boost engagement or drive performance, research shows employees may actually become more critical of their work and less willing to perform mundane tasks.

Towards true workplace transformation

Mindfulness alone cannot fix a toxic workplace. When organizations introduce mindfulness programs without first addressing the underlying causes of stress or toxicity, they’re unlikely to see the results they expect.

If organizations want to reap the full benefits of mindfulness and self-compassion, they need to take a more deliberate, structured approach. Psychologist Kurt Lewin’s three-step change management model offers a useful guide:

Step 1. Unfreeze: Address the root causes of workplace stress

Address systemic stressors. Before introducing any well-being initiative, organizations must confront actual sources of stress such as excessive workloads, toxic leadership and job insecurity.
Correct misunderstandings. Clarify what mindfulness and self-compassion actually is to reduce scepticism and confusion.
Avoid mandatory participation. Giving employees the freedom to opt in fosters authentic engagement and sustains interest.

Step 2. Change: Implement practices ethically and intentionally

Lead by example at the top. Instead of only offering these programs to employees, leaders should engage with mindfulness and self-compassion practices themselves. When senior figures lead by example, these programs gain legitimacy and workplaces foster more ethical, people-centered leadership that goes beyond performance and productivity.
Ensure cultural sensitivity. Small cultural adaptations can improve the inclusion of mindfulness and self-compassion sessions. For instance, research has found that in Hispanic communities, using familiar stories or proverbs can make mindfulness sessions more relatable and improve engagement.
Preserve ethical foundations. Present mindfulness and self-compassion as universal practices, not tied to any one religion. This preserves their ethical underpinnings while ensuring they remain universal and accessible to all.

Step 3. Freeze: Embed mindfulness and self-compassion into workplace culture

Encourage small, daily practices. Offer simple tools like journaling or mindful breathing breaks that employees can tailor to their own needs and schedules.
Provide ongoing support. Create time and space for continued practice, such as guided meditations, mindfulness moments in meetings or gratitude boards so new habits take root.
Measure impact holistically. Consider hiring qualified professionals to evaluate program effectiveness, address emerging needs and keep the organization moving forward.

Moving beyond wellness window-dressing

Mindfulness and self-compassion are not magic bullets, but they can still be powerful catalysts for change.

When introduced with a deliberate and thoughtful approach, mindfulness and self-compassion can help workplaces move beyond shallow wellness “hacks” toward truly transformative practices, even in high-pressure, profit-driven environments.

Far from serving as a quick fix or a mere productivity tool, these practices encourage employees to challenge the status quo, take meaningful action, build healthier relationships and make more ethical decisions. They can help individual employees flourish within and beyond their workplaces.

The true value of mindfulness and self-compassion practices lies not in short-term outcomes or surface-level improvements, but in helping individuals be more aware of themselves, their surroundings and the choices they make, which is beyond any outcome or context.

Parental controls on children’s tech devices are out of touch with child’s play

Source: The Conversation – Canada – By Sara M. Grimes, Wolfe Chair in Scientific and Technological Literacy and Professor, McGill University

Parenting in the digital age can be stressful and demands a lot from parents.

The Family Online Safety Institute (FOSI) recently released its annual Online Safety Survey that discovered almost 50 per cent of parents surveyed aren’t using parental controls to manage their children’s devices. These are tools that would ostensibly help parents filter out inappropriate content or unwanted interactions on their children’s devices.

The FOSI authors conclude the reason parents aren’t using the tools is because they feel “overwhelmed” and recommend parents educate themselves as a good first step toward broader use.

While overwhelm is a real thing, we suggest a bigger problem with parental controls is how they are designed. This includes how little attention is given to supporting open communication between parents and children.

Once a year for the past three years, we’ve asked the same 33 children (initially aged six to 12) what they think about content ratings, online safety, game monetization and privacy.
Our team’s combined expertise in communication, education, policy and game studies analyzed their answers.

We also asked their parents how they mediated their kids’ gaming. Nearly half of them don’t use parental controls either. They say parental controls don’t always work as promised, offer little context about how settings affect gameplay and force binary choices that don’t align with household rules or with children’s maturity levels.

The parents we asked said they aren’t avoiding parental controls because they feel overwhelmed by them. It’s that the tools are poorly designed.

Parent controls can introduce more problems

At the same time, many of the parents described themselves as highly engaged in their child’s gameplay; talking with their children regularly or encouraging play in shared, supervised spaces. Several said they choose to trust their child rather than set top-down limits.

Our findings align with previous research on digital parenting. In one British study, parents said they felt some controls were valuable supplements to mediation, while other controls were poorly designed, introducing more problems than solutions.

The use of parental controls doesn’t necessarily translate to increased child safety. In fact, using parental controls can create a disconnect between parents and children on key safety issues.

Awareness of risks

Six children we interviewed were not aware their parents were using controls, and at least two children revealed they didn’t even know why a parent would use parental controls in the first place. In this context, parents’ efforts to protect their children had the unintended side effect of obscuring vital knowledge, leaving the children unaware of some of the key risks associated with playing online. Parental controls can remove opportunities to teach kids about safety if they aren’t part of the conversation.

We believe that the behind-the-scenes protections enabled by (some) parental controls can be detrimental to parent-child communication about online safety. What are the risks? How can children avoid the riskiest behaviour? What should they do when or if they’ve encountered danger?

Meanwhile, parents aren’t always familiar with the features and activities they are asked to restrict or allow. Very few parental controls contain information about how gameplay will be impacted by their settings. Many contain terms only someone familiar with the game would understand, while others are hard to navigate.

All of this can lead to misinterpretations and parent-child conflicts, making the tools even harder to use.

Power of communication

Open communication between parents and children on safety topics fosters trust, which increases the likelihood kids will turn to their parents for help when something dangerous happens.

It enables children to build resiliency, which in turn reduces the risk they’ll be harmed by negative online encounters.

Research also suggests that parent-child communication may be more effective at helping to avoid harm than embedded restrictions enabled by parental controls.

The importance of open communication is also emphasized in the FOSI report. In households where conversations about online safety happened regularly (six times or more a year), parents and children were both more likely to view parental controls as a useful and valuable tool for online safety.

This, the authors conclude, “supports the view of online safety as a collaborative effort as opposed to a priority imposed by parents on their children.”

On this point, we couldn’t agree more. Families would benefit from making parental controls and safety settings a family affair. Kids and parents have a lot to learn from each other about the digital world, and reviewing these systems together can provide a much-needed opening for crucial conversations about risk, safety and what kids find meaningful about digital play.

Rethinking safety tools

Let’s not pretend parental controls are a panacea for child safety.

Many parental controls contain serious design flaws and limitations. Very few comprehensively address the needs and concerns of either children or their parents.

Now that lawmakers are starting to make parental controls a mandatory part of new child safety legislation, we urgently need to start taking a closer and more critical look at what they can and can’t do.

Parental controls can be a useful tool when they are designed well, applied with transparency, and provide families with ample options so they can be tailored to not only fit with but foster household rules and open communication.

There’s a lot of work to be done before this is the standard. But also a growing impetus for game and other tech companies to make it happen.
