As NASA faces potential budget cuts, China is unveiling an ambitious series of deep space missions -- including Mars sample returns, outer planet exploration, and a future Mars base. While some of China's plans are aspirational, their track record of successful missions lends credibility to their expanding role in space. Ars Technica reports: China created a new entity called the "Deep Space Exploration Laboratory" three years ago to strengthen the country's approach to exploring the Solar System. Located in eastern China, not far from Shanghai, the new laboratory represented a partnership between China's national space agency and a local public college, the University of Science and Technology of China.

Not much is known outside of China about the laboratory, but it has recently revealed some very ambitious plans to explore the Solar System, including the outer planets. This week, as part of a presentation, Chinese officials shared some public dates about future missions. Space journalist Andrew Jones, who tracks China's space program, shared some images with a few details. Among the planned missions are:

- 2028: Tianwen-3 mission to collect samples of Martian soil and rocks and return them to Earth
- 2029: Tianwen-4 mission to explore Jupiter and its moon Callisto
- 2030: Development of a large, ground-based habitat to simulate long-duration human spaceflight
- 2033: Mission to Venus that will return samples of its atmosphere to Earth
- 2038: Establishment of an autonomous Mars research station to study in-situ resource utilization
- 2039: Mission to Triton, Neptune's largest moon, with a subsurface explorer for its ocean

sciencehabit quotes a report from Science.org: Whales sing, orcas squeal, and sea turtles croak. But sharks are more the strong, silent type. Now, researchers report the first evidence that sharks make sounds, too, described today in Royal Society Open Science. The animals may be making the sounds -- a series of clicking noises -- by snapping their flat rows of teeth, which are blunt for crushing prey. The sharks can hear mostly low-frequency noise, and the clicks they emit are higher pitched, which suggests they are not for communicating with other rigs. It's possible they are a defensive tactic. Marine mammals that eat rigs, such as leopard seals, can hear in the frequency range of the rig clicks, but the researchers question whether a few clicks would deter an attack. The sounds might be part of their response to being startled, the team says.

An anonymous reader quotes a report from Gizmodo: Scientists scrutinizing the seafloor beneath a calving iceberg found a remarkable array of living creatures, switching up notions of how the giant chunks of ice affect their immediate environs. The scientists investigated a region of seafloor recently exposed by the calving of a gigantic iceberg -- A-84 -- which is as large as Chicago. The team found a surprisingly vibrant community of critters on the seafloor below where A-84 was once attached to an ice shelf attached to Antarctica.

Without the 197-square-mile (510-square-kilometer) iceberg in the way, the team was able to scrutinize the seafloor at depths of 4,265 feet (1,300 meters) using the remotely operated vehicle (ROV) SuBastian. The team found large corals and sponges supporting other lifeforms, including icefish, giant sea spiders, and octopus. [...] With the icebergs covering the seafloor, organisms below the shelf cannot get nutrients for survival from the surface. The team hypothesized that ocean currents are a critical driver for life beneath the ice sheets. The team also collected data on the larger ice sheet, whose shrinking size spells concern for the animals that live beneath it.

NASA's Curiosity rover has detected the largest organic molecules ever found on Mars -- decane, undecane, and dodecane -- suggesting that complex prebiotic chemistry may have occurred in the planet's ancient lakebeds. The findings have been published in the Proceedings of the National Academy of Sciences. From a press release: Scientists probed an existing rock sample inside Curiosity's Sample Analysis at Mars (SAM) mini-lab and found the molecules decane, undecane, and dodecane. These compounds, which are made up of 10, 11, and 12 carbons, respectively, are thought to be the fragments of fatty acids that were preserved in the sample. Fatty acids are among the organic molecules that on Earth are chemical building blocks of life. Living things produce fatty acids to help form cell membranes and perform various other functions. But fatty acids also can be made without life, through chemical reactions triggered by various geological processes, including the interaction of water with minerals in hydrothermal vents.

While there's no way to confirm the source of the molecules identified, finding them at all is exciting for Curiosity's science team for a couple of reasons. Curiosity scientists had previously discovered small, simple organic molecules on Mars, but finding these larger compounds provides the first evidence that organic chemistry advanced toward the kind of complexity required for an origin of life on Mars. The new study also increases the chances that large organic molecules that can be made only in the presence of life, known as "biosignatures," could be preserved on Mars, allaying concerns that such compounds get destroyed after tens of millions of years of exposure to intense radiation and oxidation.

Long-time Slashdot reader invisik reminds us that the "fish doorbell" is still going strong, according to the Associated Press. "Now in its fifth year, the site has attracted millions of viewers from around the world with its quirky mix of slow TV and ecological activism." The central Dutch city of Utrecht installed a "fish doorbell" on a river lock that lets viewers of an online livestream alert authorities to fish being held up as they make their springtime migration to shallow spawning grounds. The idea is simple: An underwater camera at Utrecht's Weerdsluis lock sends live footage to a website. When somebody watching the site sees a fish, they can click a button that sends a screenshot to organizers. When they see enough fish, they alert a water worker who opens the lock to let the fish swim through.
"Much of the time, the screen is just a murky green with occasional bubbles, but sometimes a fish swims past. As the water warms up, more fish show up..."

The devastating impacts of the climate crisis reached new heights in 2024, with scores of unprecedented heatwaves, floods and storms across the globe, according to the UN's World Meteorological Organization. From a report: The WMO's report on 2024, the hottest year on record, sets out a trail of destruction from extreme weather that took lives, demolished buildings and ravaged vital crops. More than 800,000 people were displaced and made homeless, the highest yearly number since records began in 2008.

The report lists 151 unprecedented extreme weather events in 2024, meaning they were worse than any ever recorded in the region. Heatwaves in Japan left hundreds of thousands of people struck down by heatstroke. Soaring temperatures during heatwaves peaked at 49.9C at Carnarvon in Western Australia, 49.7C in the city of Tabas in Iran, and 48.5C in a nationwide heatwave in Mali.

Record rains in Italy led to floods, landslides and electricity blackouts; torrents destroyed thousands of homes in Senegal; and flash floods in Pakistan and Brazil caused major crop losses.

Storms were also supercharged by global heating in 2024, with an unprecedented six typhoons in under a month hitting the Philippines. Hurricane Helene was the strongest ever recorded to strike the Big Bend region of Florida in the US, while Vietnam was hit by Super Typhoon Yagi, affecting 3.6 million people. Many more unprecedented events will have passed unrecorded.

NASA's SpaceX Crew-9 has returned to Earth safely after a stay of more than nine months aboard the International Space Station. The crew remained in space longer than expected due to issues with Boeing's Starliner capsule, which was originally scheduled to bring them home sooner.

While the mission has been politically fraught, the astronauts said in a rare space-to-earth interview last month that they were neither stranded nor abandoned. "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck -- and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.' That's what we prefer..." CNN has more details on the arrival: Williams and Wilmore, alongside NASA's Nick Hague and cosmonaut Aleksandr Gorbunov of Russia's Roscosmos space agency, safely splashed down off the coast of Tallahassee, Florida at 5:57 p.m. ET. The crew's highly anticipated return came after the crew climbed aboard a SpaceX Crew Dragon capsule and departed the International Space Station at 1:05 a.m. ET. Williams, Wilmore, Hague and Gorbunov spent Tuesday morning and afternoon in orbit in the roughly 13-foot-wide (4-meter-wide), gumdrop-shaped SpaceX Crew Dragon spacecraft. Gradually descending, the capsule carried the astronauts from the space station, which orbits about 250 miles (400 kilometers) above Earth, toward the thick inner layer of our planet's atmosphere.

Around 5 p.m. ET, the Crew Dragon capsule began firing its engines to begin the final phase of the journey: reentry. This leg of the journey is considered the most dangerous of any flight home from space. The jarring physics of hitting the atmosphere while traveling more than 22 times the speed of sound routinely heats the exterior of returning spacecraft to more than 3,500 degrees Fahrenheit (1,926 degrees Celsius) and can trigger a communication blackout. After plunging toward home, the Crew Dragon spacecraft deployed two sets of parachutes in quick succession to further slow its descent. The capsule decelerated from orbital speeds of more than 17,000 miles per hour (27,359 kilometers per hour) to less than 20 miles per hour (32 kilometers per hour) as the vehicle hit the ocean.

After the vehicle hit the ocean, a SpaceX rescue ship waiting nearby worked to haul the spacecraft out of the water. Williams and Wilmore and their crewmates will soon exit Dragon and take their first breaths of earthly air in nine months. Medical teams will evaluate the crew's health, as is routine after astronauts return from space, before deciding next steps. Ultimately, the NASA crew members will return to their home base at Johnson Space Center in Houston. You can watch a recording of the re-entry and splashdown here.

The Washington Post reports: Oceans last year reached their highest levels in three decades — with the rate of global sea level rise increasing around 35% higher than expected, according to a NASA-led analysis published Thursday... Last year's rate of average global sea level rise was 0.23 inches per year, higher than the expected 0.17 inches per year, NASA said in a news release.

The rate of global sea level rise follows a trend of rapidly increasing rates over the past 30 years. From 1993 to 2023, the rate of global sea level rise doubled, increasing from 0.08 inches per year to 0.18 inches, another NASA-led study showed. Overall, the global sea level has climbed by 4 inches since 1993.
More details from ABC News: Climate change was a major driver to an unexpected level of sea level rise in 2024, according to a new NASA analysis... The majority of the difference between predicted and actual sea level rise was attributed to thermal expansion — or the ocean waters expanding as they warm, researchers said. An unusual amount of ocean warming, combined with meltwater from land-based ice such as glaciers, led to the increase of sea level rise last year, according to NASA.

About two-thirds of sea level rise in recent years has resulted from the melting of ice sheets and glaciers, with a third coming from thermal expansion, according to NASA. In 2024, those metrics flipped, with two-thirds of the rise attributed to expanding ocean water and one-third attributed to contributions from melting ice. "With 2024 as the warmest year on record, Earth's expanding oceans are following suit, reaching their highest levels in three decades," said Nadya Vinogradova Shiffer, head of physical oceanography programs and the Integrated Earth System Observatory at NASA... Human-amplified climate change is the primary cause for present-day rising sea levels, climate research shows.

"A new four-lane highway cutting through tens of thousands of acres of protected Amazon rainforest is being built for the COP30 climate summit," reports the BBC, "in the Brazilian city of Belém."

The highway will ease traffic into the city, which will host over 50,000 people at the conference this November: The state government touts the highway's "sustainable" credentials, but some locals and conservationists are outraged at the environmental impact... Along the partially built road, lush rainforest towers on either side — a reminder of what was once there. Logs are piled high in the cleared land which stretches more than 13km (8 miles) through the rainforest into Belém.

Diggers and machines carve through the forest floor, paving over wetland to surface the road which will cut through a protected area... The road leaves two disconnected areas of protected forest. Scientists are concerned it will fragment the ecosystem and disrupt the movement of wildlife...

The state government of Pará had touted the idea of this highway, known as Avenida Liberdade, as early as 2012, but it had repeatedly been shelved because of environmental concerns. Now a host of infrastructure projects have been resurrected or approved to prepare the city for the COP summit.
But on the bright side, Adler Silveira, the state government's infrastructure secretary, said the highway would have wildlife crossings for animals to pass over, as well as climate-friendly bike lanes and solar-powered lighting...

"For the first time in history, a privately operated lunar lander has captured images of a total eclipse from the Moon's surface," reports Daily Galaxy.

While the Athena lunar lander tipped over and ended its mission, elsewhere on the moon Firefly Aerospace's Blue Ghost lunar lander "continues to beam home incredible imagery," writes Space.com, and since its landing on March 2 "has been sending us stunning photos and videos..." A new video of Blue Ghost's moon-side view captures the eerie red light on the moon (caused by sunlight refracting through the atmosphere over the edges of the earth). "Blue Ghost turns red!" Firefly writes on their mission updates page.

A SpaceX photographer also captured the eclipse as it happened over a Falcon 9 rocket waiting to launch to the International Space Station, in a remarkable time-lapse photograph.

And Space.com collects more interesting lunar-eclipse photos taken from around the world, including Appin, Scotland; Canberra, Australia; and Palm Springs, California...

Cities in Europe "are dramatically scaling back their relationship with the car," reports the Washington Post: They are removing parking spaces and creating dedicated bike lanes. They are installing cameras at the perimeter of urban centers and either charging the most-polluting vehicles or preventing them from entering. Some are going so far as to put entire neighborhoods off-limits to vehicles. In Norway, Oslo promotes "car-free livability." Paris Mayor Anne Hidalgo touts the "end of car dependence." And while those ideas might sound radical to car-loving Americans, they are fast becoming the norm across the Atlantic, where 340 European cities and towns — home to more than 150 million people — have implemented some kind of restrictions on personal car usage...

[V]irtually every major European city is imposing some kind of rule. Milan has a system similar to New York's, charging for access to the city core — while entirely banning older, highly polluting vehicles. London charges vehicles that don't meet emissions standards, in what it calls the "largest clean-air zone in the world." The programs are not just the purview of liberal Western Europe: Warsaw, Poland, and Sofia, Bulgaria, recently adopted similar schemes. Even little Italian villages have added vehicle restrictions to reinforce their historic feel. And the Netherlands just broke ground on a 12,000-person neighborhood that will be entirely car-free. The neighborhood, known as Merwede, will be connected by public transport to Utrecht, a medium-size city that — perhaps no surprise — has a low-emissions zone of its own...

Perhaps the most elaborate and transformative effort has come in Paris, where Anne Hidalgo was elected mayor in 2014. Since then, Paris has banned the most-polluting vehicles from the city, eliminated 50,000 parking spaces and added hundreds of miles of bike lanes. It turned a bank of the Seine from a busy artery into a pedestrian zone, and closed off the famed Rue de Rivoli to traffic... Journeys by car in Paris have dropped by about 45 percent since 1990. The city has now become a source for striking before-and-after photos: of clogged streets that have transitioned into tree-lined areas where people can walk and play.
In London government officials say inhalable particular matter has fallen, according to the article, while combustion-produced nitrogen dioxide "is 53% lower than it would have been without the restrictions."

Slashdot has run nearly a dozen stories about Michael Mann, one of America's most prominent climate scientists and a co-creator of the famous "hockey stick" graph of spiking temperatures. In 2012 Mann sued two bloggers for defamation — and last year Mann finally won more than $1 million, reports the Washington Post. "A jury found that two conservative commentators had defamed him by alleging that he was like a child molester in the way he had 'molested and tortured' climate data."

But "Now, a year after that ruling, the case has taken a turn that leaves Mann in the position of the one who owes money." On Wednesday, a judge sanctioned Mann's legal team for "bad-faith trial misconduct" for overstating how much the scientist lost in potential grant funding as a result of reputational harm. The lawyers had shown jurors a chart that listed one grant amount Mann didn't get at $9.7 million, though in other testimony Mann said it was worth $112,000. And when comparing Mann's grant income before and after the negative commentary, the lawyers cited a disparity of $2.8 million, but an amended calculation pegged it at $2.37 million.


The climate scientist's legal team said it was preparing to fight the setbacks in court. Peter J. Fontaine, one of Mann's attorneys, wrote in an email that Mann "believes that the court committed errors of fact and law and will pursue these matters further." Fontaine emphasized that the original decision — that Mann was defamed by the commentary — still stands. "We have reviewed the recent rulings by the D.C. Superior Court and are pleased to note that the court has upheld the jury's verdict," he said.

Astronomers using the Canada-France-Hawaii Telescope have discovered 128 new moons around Saturn, bringing its total to 274 -- more than all the other planets combined. CBC News reports: Jupiter and Saturn have been locked in a battle for the most moons for years -- with Saturn stealing the crown from Jupiter only two years ago when the same group of researchers found 64 additional moons orbiting it. But scientists say this discovery likely settles the score once and for all. [...] He and the other scientists working on the project made the discovery using the Canada France Hawaii Telescope, a 3.6-meter optical telescope on the summit of the dormant volcano Mauna Kea on the Big Island of Hawaii.

Scientists have been capturing pictures of the moons using the telescope since 2019. The researchers aligned and layered 44 of those images on top of one another in order to enhance the appearance of the moons and determine what they were. These moons are nothing like Earth's very own, however. Sara Mazrouei, a planetary scientist and educational developer at Humber Polytechnic, says that while we tend to think of a spherical shape when we hear the word moon, anything that orbits a planet, or another body in space that is not a sun, is considered a moon. Mazrouei says many of the moons surrounding other planets in our solar system -- including the ones observed here -- are in fact only a few kilometers across in size and oddly shaped, like an asteroid.

A SpaceX Falcon 9 rocket launched a four-member crew to the International Space Station on Friday night, paving the way for NASA astronauts Butch Wilmore and Suni Williams to return to Earth after being there for nine months due to issues with Boeing's Starliner capsule. Arrival is set for late Saturday night. The Associated Press reports: NASA wants overlap between the two crews so Wilmore and Williams can fill in the newcomers on happenings aboard the orbiting lab. That would put them on course for an undocking next week and a splashdown off the Florida coast, weather permitting. The duo will be escorted back by astronauts who flew up on a rescue mission on SpaceX last September alongside two empty seats reserved for Wilmore and Williams on the return leg.

Reaching orbit from NASA's Kennedy Space Center, the newest crew includes NASA's Anne McClain and Nichole Ayers, both military pilots; and Japan's Takuya Onishi and Russia's Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free. "Spaceflight is tough, but humans are tougher," McClain said minutes into the flight. You can watch a recording of the launch here.

Wilmore and Williams aren't stranded on the International Space Station, and they weren't abandoned, the astronauts reminded CNN in a rare space-to-earth interview last month. "That's been the rhetoric. That's been the narrative from day one: stranded, abandoned, stuck -- and I get it. We both get it," [NASA astronaut Butch] Wilmore said. "But that is, again, not what our human spaceflight program is about. We don't feel abandoned, we don't feel stuck, we don't feel stranded." Wilmore added a request: "If you'll help us change the rhetoric, help us change the narrative. Let's change it to 'prepared and committed.' That's what we prefer..."

Breakthrough Energy, the climate group founded by Bill Gates, has laid off dozens of employees in the U.S. and Europe, eliminating its public policy and partnerships teams as it shifts away from advocacy work. Its investment and grantmaking divisions will remain unaffected. The Detroit News reports: Breakthrough Energy is an umbrella organization founded by Gates that houses various initiatives aimed at accelerating the clean energy transition. It also encompasses Breakthrough Energy Ventures, one of the biggest investors in early-stage climate technologies with stakes in more than 120 companies, as well as a grantmaking program for early-seed stage company founders and Breakthrough Catalyst, a funding platform focused on emergent climate technologies. None of those divisions of the group were impacted by cuts, which were reported earlier by the New York Times.

[...] "In the United States especially, the conversation about climate has been sidetracked by politics," Gates wrote in the introduction to his 2021 book. "Some days, it can seem as if we have little hope of getting anything done." The climate pullback is happening at the same time as the US cuts foreign aid, a field where Gates is also a major donor. His nonprofit, the Gates Foundation, operates with a budget of billions and has a strong focus on overseas development. "Bill Gates remains as committed as ever to advancing the clean energy innovations needed to address climate change," a Breakthrough Energy spokesperson said in an emailed statement. "His work in this area will continue and is focused on helping drive reliable affordable, clean energy solutions that will enable people everywhere to thrive."

On Wednesday, the EPA announced the agency will "undertake 31 historic actions in the greatest and most consequential day of deregulation in U.S. history..."

A new study published in the Journal of Geophysical Research Planets reveals that atmospheric gravity waves play a crucial role in driving latitudinal air currents on Mars, particularly at high altitudes. Phys.Org reports: The study applied methods developed to explore Earth's atmosphere to quantitatively estimate the influence of gravity waves on Mars' planetary circulation. [...] "On Earth, large-scale atmospheric waves caused by the planet's rotation, known as Rossby waves, are the primary influence on the way air circulates in the stratosphere, or the lower part of the middle atmosphere. But our study shows that on Mars, gravity waves (GWs) have a dominant effect at the mid and high latitudes of the middle atmosphere," said Professor Kaoru Sato from the Department of Earth and Planetary Science. "Rossby waves are large-scale atmospheric waves, or resolved waves, whereas GWs are unresolved waves, meaning they are too fine to be directly measured or modeled and must be estimated by more indirect means."

Not to be confused with gravitational waves from massive stellar bodies, GWs are an atmospheric phenomenon when a packet of air rises and falls due to variations in buoyancy. That oscillating motion is what gives rise to GWs. Due to the small-scale nature of them and the limitations of observational data, researchers have previously found it challenging to quantify their significance in the Martian atmosphere. So Sato and her team turned to the Ensemble Mars Atmosphere Reanalysis System (EMARS) dataset, produced by a range of space-based observations over many years, to analyze seasonal variations up there.

"We found something interesting, that GWs facilitate the rapid vertical transfer of angular momentum, significantly influencing the meridional, or north-south, in the middle atmosphere circulations on Mars," said graduate student Anzu Asumi. "It's interesting because it more closely resembles the behavior seen in Earth's mesosphere rather than in our stratosphere. This suggests existing Martian atmospheric circulation models may need to be refined to better incorporate these wave effects, potentially improving future climate and weather simulations."

A new statistical analysis has identified the films audiences "love to hate," with Battlefield Earth, Morbius, Grease 2, and Cats topping the list of cinema's most detested productions. The study, published by data analyst Daniel Parris, examined review data from MovieLens to calculate both the percentage of one-star reviews and total disapproval magnitude for each release.

A common thread among these widely derided titles: many were adaptations of popular books or shows, or attempted to capitalize on once-beloved franchises. Adam Sandler leads the actors most frequently appearing in widely disliked films, followed by comedians and action stars who have starred in productions with high one-star review rates.

The research also reveals an industry trend toward increasing one-star reviews over time, with family-oriented fare and horror films receiving disproportionately negative ratings despite consistent box office profitability - suggesting studios have prioritized risk-averse, commercially viable projects over critical acclaim.

An anonymous reader quotes a report from TechCrunch: There's a power crunch looming as AI and cloud providers ramp up data center construction. But a new report suggests that a solution lies beneath their foundations. Advanced geothermal power could supply nearly two-thirds of new data center demand by 2030, according to an analysis by the Rhodium Group. The additions would quadruple the amount of geothermal power capacity in the U.S. -- from 4 gigawatts to about 16 gigawatts -- while costing the same or less than what data center operators pay today. In the western U.S., where geothermal resources are more plentiful, the technology could provide 100% of new data center demand. Phoenix, for example, could add 3.8 gigawatts of data center capacity without building a single new conventional power plant.

Geothermal resources have enormous potential to provide consistent power. Historically, geothermal power plants have been limited to places where Earth's heat seeps close to the surface. But advanced geothermal techniques could unlock 90 gigawatts of clean power in the U.S. alone, according to the U.S. Department of Energy. [...] Because geothermal power has very low running costs, its price is competitive with data centers' energy costs today, the Rhodium report said. When data centers are sited similarly to how they are today, a process that typically takes into account proximity to fiber optics and major metro areas, geothermal power costs just over $75 per megawatt hour. But when developers account for geothermal potential in their siting, the costs drop significantly, down to around $50 per megawatt hour.

The report assumes that new generating capacity would be "behind the meter," which is what experts call power plants that are hooked up directly to a customer, bypassing the grid. Wait times for new power plants to connect to the grid can stretch on for years. As a result, behind the meter arrangements have become more appealing for data center operators who are scrambling to build new capacity.

Sphere Entertainment Co, the company behind the Las Vegas Sphere, said they are considering opening scaled-down versions of the immersive venue in other cities. AV Magazine reports: While this has been been feasible for its high-profile residencies such as U2, the Eagles, Dead & Company and Anyma, smaller venues could attract a broader range of artists who might not have the budget or demand to fill the flagship Las Vegas location. By scaling down the size while retaining the signature technology, Sphere Entertainment Co can offer a similar spectacle at a more sustainable cost for artists and spectators.

The possibility of mini-Spheres follows news that a full-scale venue will open in the UAE as a result of a partnership between Sphere Entertainment Co and the Department of Culture and Tourism -- Abu Dhabi. Beyond concerts, the Las Vegas Sphere has proven successful with immersive films such as V-U2: An Immersive Concert Film and the Sphere Expeience featuring Darren Aronofsky's Postcard from Earth, which In January passed 1,000 screenings. "As we enter a new fiscal year, we see significant opportunities to drive our Sphere business forward in Las Vegas and beyond," said Dolan. "We believe we are on a path toward realizing our vision for this next-generation medium and generating long-term shareholder value."

Nearly every country on Earth has dirtier air than doctors recommend breathing, a report has found. From a report: Only seven countries met the World Health Organization's guidelines for tiny toxic particles known as PM2.5 last year, according to analysis from the Swiss air quality technology company IQAir. Australia, New Zealand and Estonia were among the handful of countries with a yearly average of no more than 5ug of PM2.5 per cubic metre, along with Iceland and some small island states.

The most polluted countries were Chad, Bangladesh, Pakistan, the Democratic Republic of the Congo and India. PM2.5 levels in all five countries were at least 10 times higher than guideline limits in 2024, the report found, stretching as much as 18 times higher than recommended levels in Chad. Doctors say there are no safe levels of PM2.5, which is small enough to slip into the bloodstream and damage organs throughout the body, but have estimated millions of lives could be saved each year by following their guidelines. Dirty air is the second-biggest risk factor for dying after high blood pressure.
