Antarctica Has Lost 7.5tn Tonnes of Ice Since 1997, Scientists Find 71

More than 40% of Antarctica's ice shelves have shrunk since 1997 with almost half showing "no sign of recovery," a study has found, linking the change to the climate breakdown. From a report: Scientists at the University of Leeds have calculated that 67tn tonnes of ice was lost in the west while 59tn tonnes was added to the east between 1997 and 2021, resulting in a net loss of 7.5tn tonnes. Warm water on the western side of Antarctica has been melting ice, whereas in the east, ice shelves have either stayed the same or grown as the water is colder there. The ice shelves sit at the end of glaciers and slow their rate of flow into the sea. When they shrink, glaciers release larger amounts of freshwater into the sea which can disrupt the currents of the Southern Ocean.

Dr Benjamin Davison, an expert in Earth observation and the study's lead, said: "There is a mixed picture of ice-shelf deterioration, and this is to do with the ocean temperature and ocean currents around Antarctica. The western half is exposed to warm water, which can rapidly erode the ice shelves from below, whereas much of east Antarctica is currently protected from nearby warm water by a band of cold water at the coast." Scientists measured year-by-year changes to the ice using satellites that can see through the thick cloud during long polar nights.

NASA Launches Psyche, a Mission To Explore a Metal Asteroid (nytimes.com) 24

Is the asteroid Psyche really a hunk of mostly metal? Is the object, which is nearly as wide as Massachusetts, the core of a baby planet whose rocky outer layers were knocked off during a cataclysmic collision in the early days of the solar system? Right now, all that astronomers can say is maybe, maybe not. NASA launched a spacecraft on Friday morning, also named Psyche, on a journey to the asteroid belt between Mars and Jupiter to find out. From a report: "We're really going to see a kind of new object, which means that a lot of our ideas are going to be proven wrong," said Lindy Elkins-Tanton, a professor of earth and space exploration at Arizona State University who serves as the mission's principal investigator.

Being proven wrong, she added, "is, I think, the most exciting thing in science." That voyage in search of answers kicked off Friday at 10:19 a.m. Eastern time. Falcon Heavy, the largest of SpaceX's operational rockets, lifted off from Kennedy Space Center in Florida, sending the massive spacecraft on a journey that will last about six years and travel billions of miles. Friday's flight overcame early, unfavorable weather forecasts for a seemingly flawless flight. About eight minutes into the flight, the rocket's upper stage entered a 45-minute coasting period during which it will prepare to deploy the spacecraft on its flight away from Earth. The asteroid named Psyche has long been a curious enigma. Spotted in 1852 by Annibale de Gasparis, an Italian astronomer, it is named for the Greek goddess of the soul, and it was just the 16th asteroid to be discovered. In the early observations, it was, like the other asteroids, a starlike point of light that moved in an orbit around the sun, and not much more.

People Send 20 Billion Pounds of 'Invisible' E-Waste To Landfills Each Year 106

An anonymous reader quotes a report from Popular Science: One e-toy for every person on Earth -- that's the staggering amount of electric trains, drones, talking dolls, R/C cars, and other children's gadgets tossed into landfills every year. Some of what most consumers consider to be e-waste -- like electronics such as computers, smartphones, TVs, and speaker systems -- are usual suspects. Others, like power tools, vapes, LED accessories, USB cables, anything involving rechargeable lithium batteries and countless other similar, "nontraditional" e-waste materials, are less obviously in need of special disposal. In all, people across the world throw out roughly 9 billion kilograms (19.8 billion pounds) of e-waste commonly not recognized as such by consumers.

This "invisible e-waste" is the focal point of the sixth annual International E-Waste Day on October 14, organized by Waste Electrical and Electronic Equipment (WEEE) Forum. In anticipation of the event, the organization recently commissioned the United Nations Institute for Training and Research (UNITAR) to delve into just how much unconventional e-waste is discarded every year -- and global population numbers are just some of the ways to visualize the issue.

According to UNITAR's findings, for example, the total weight of all e-cig vapes thrown away every year roughly equals 6 Eiffel Towers. Meanwhile, the total weight of all invisible e-waste tallies up to "almost half a million 40 [metric ton] trucks," enough to create a bumper-to-bumper traffic jam stretching approximately 3,504 miles -- the distance between Rome and Nairobi. From a purely economic standpoint, nearly $10 billion in essential raw materials is literally thrown into the garbage every year.

Croatia Wants To Turn Superhot Underground Lake Into a 16MW Geothermal Power Plant (thenextweb.com) 91

A Croatian energy company has discovered an underwater lake of superheated water that meets all the requirements for the construction of a 16MW geothermal power plant. The Next Web reports: The find was the result of a two-year study by state-run power company Bukotermal that sought to find suitable sites for the exploitation of the energy source, generated by heat from the Earth's core. The research verified the presence of a geothermal water source at Lunjkovec -- Kutnjak field, located in the Varazdin County, close to the border with Hungary. The underground lake, located at a depth of 2.4 kilometers, has an average temperature of 142.03 degrees Celsius.

To date, over 2.5 million euros has been invested in the project. However, according to Alen Pozgaj, CEO of Bukotermal, the total cost to build the plant would be around 50 million euros. The news comes just days after the Croatian Ministry of Economy and Sustainable Development awarded five licenses for the exploration of geothermal waters to firms from Croatia, the United Kingdom, and Turkey. [...] For now, Bukotermal has a six-month timeframe to propose how it will exploit the newly discovered geothermal pool. The company plans to construct one or more geothermal power plants and heat utilization facilities at the site, with construction expected to start within two years time.

NASA Unveils First Glimpse of Space Rock Collected From Asteroid (nytimes.com) 17

The jackpot from a seven-year mission to bring back bits of an asteroid was unveiled on Wednesday. From a report: NASA officials in Houston displayed images of salt-and-pepper chunks of rock and particles of dark space dust that were brought back to Earth from the asteroid, Bennu, and described initial scientific observations about the material. The mission, Osiris-Rex, concluded in September when a capsule full of asteroid was jettisoned through Earth's atmosphere and recovered in the Utah desert. The first pieces of materials that leaked outside the container were analyzed using a variety of laboratory techniques, revealing just the earliest findings.

Scientists found water molecules trapped in clay minerals -- water from asteroids similar to Bennu could have filled Earth's oceans. "The reason that Earth is a habitable world, that we have oceans and lakes and rivers and rain, is because these clay minerals, like minerals, like the ones we're seeing from Bennu, landed on Earth four billion years ago," Dante Lauretta, the mission's principal investigator, said during a NASA event on Wednesday. The materials also contained sulfur, key for many geological transformations in rocks.

"It determines how quickly things melt and it is also critical for biology," said Dr. Lauretta, who displayed microscopic images and 3-D visualizations of the material. The scientists also found magnetite, an iron oxide mineral that can play an important role as a catalyst in organic chemical reactions. "We're looking at the kinds of minerals that may have played a central role in the origin of life on Earth," Dr. Lauretta said. The samples are also chock-full of carbon, the element that is the building block for life.

Can These Fungus-Studying Scientists Make the Planet More Resilient to Climate Change? (msn.com) 49

A team of scientists drove hundreds of miles through the steppes of Kazakhstan in search of what may be one of the largest and most diverse fungi ecosystems on Earth.

The Washington Post believes their efforts "could help make the planet more resilient to climate change." When these underground fungi come together, they form sophisticated systems known as "mycorrhizal networks...." Mycorrhizal fungi often form mutually beneficial relationships with plants. They trade essential nutrients such as phosphorus and nitrogen in exchange for carbon, and act as an extended root system, allowing plants to access water they can't reach. These networks may also prove to be invaluable for transporting carbon underground, a study published in June found. About 13 gigatons of carbon fixed by vegetation — equivalent to about one-third of all carbon dioxide emissions from fossil fuels in one year — flows through underground fungi, according to an analysis of nearly 200 data sets.

In the steppe, these plant-fungal benefits may be short-lived, however. While deserts are a natural part of Kazakhstan's ecosystem, more than half of the country's vegetation and drylands is at risk of becoming desert as well. The main drivers are large-scale intensive agriculture and increasingly warm and dry temperatures brought by climate change.... Knowing what species of fungi live here is key to understanding how to protect them, said Bethan Manley, project officer at the Society for the Protection of Underground Networks who was on the expedition. It will help determine "where we might be able to have the most effective measures of not poisoning them with fungicides or not having harmful farming practices," she said.

Amazon Launches First Satellites for Kuiper Space Internet System (bloomberg.com) 38

Amazon has launched its first two satellites for its Project Kuiper, the tech giant's initiative to build a massive constellation of satellites that can provide internet coverage to Earth. From a report: An Atlas V rocket, operated by United Launch Alliance, lofted the pair of satellites en route to orbit from Florida at 2:06 p.m. local time Friday. The mission is still ongoing, and it's unclear when the satellites will be deployed from the rocket.

Project Kuiper's goal is to eventually put 3,326 satellites into low Earth orbit, where they will beam broadband internet service to the ground below, similar to Elon Musk's SpaceX Starlink. The two launched Friday, KuiperSat-1 and KuiperSat-2, are test satellites that will allow Amazon to demonstrate the ability to send and receive broadband signals. This mission has been long delayed. Amazon originally hoped to launch these satellites a year ago on a different, experimental rocket. However, the company wound up switching the launch vehicle for these satellites multiple times, eventually landing on ULA's workhorse Atlas V rocket, in order to get the satellites into space more quickly.

September Broke the Global Heat Record by a 'Gobsmackingly Bananas' Margin (bnnbloomberg.ca) 142

The global average temperature for September broke records by such an absurd margin that climate experts are struggling to describe the phenomenon. From a report: "This month was -- in my professional opinion as a climate scientist -- absolutely gobsmackingly bananas," Zeke Hausfather, a researcher with Berkeley Earth, said on the social media platforms Bluesky and X. The numbers are stark. September 2023 beat the previous record for the month, set in 2020, by 0.5C (0.9F), according to data sets maintained by the Japan Meteorological Agency and the EU's Copernicus Climate Change Service. The temperature anomaly for the month was roughly 1.7C above pre-industrial levels, which is above the symbolic 1.5C mark set as the stretch goal in the Paris Agreement.

"We've never really seen a jump anything quite of this magnitude," Hausfather said. "Half a degree C is analogous to slightly less than half of all the warming we've seen from pre-industrial [temperatures]." Carbon dioxide emissions from burning fossil fuels are the main driver of rising temperatures. The global average temperature this year has also seen a boost from El Nino, a natural climate shift in the Pacific. Other factors may also be pushing temperatures up incrementally, such as a decline in cooling aerosol pollution from ships. Hausfather said next September may be unlikely to have all the same compounding factors, and consequently may be not as extreme. But either way, he described September 2023 as a "sneak peek" of what the back-to-school month may feel like in a decade as climate change pushes temperatures higher.

A New Satellite Outshines Some of the Brightest Stars in the Sky (nytimes.com) 41

Becky Ferreira writes via the New York Times: Last November, a satellite in low-Earth orbit unfurled into an expansive array that extends across nearly 700 square feet, about the size of a studio apartment. The satellite, BlueWalker 3, has since become one of the brightest objects in the sky, outshining some of the most radiant stars in the Milky Way, according to a study published on Monday in Nature -- and it is just the first of dozens of similar satellites that are in development by AST SpaceMobile, a company that aims to keep smartphones connected from orbit. "The issue is not necessarily that one satellite," said Siegfried Eggl, an astrophysicist at the University of Illinois, Urbana-Champaign and an author of the new study, "but that it is a predecessor or prototype of a constellation, so there's going to be a lot of those out there eventually."

Initially launched in September 2022, BlueWalker 3 is the forerunner of AST SpaceMobile's BlueBird satellites, which aim to serve as a network of orbital cell towers with the goal "to democratize access to knowledge and information regardless of where people live and work," a spokesperson for AST SpaceMobile said. Last month, BlueWalker 3 successfully relayed its first 5G connection to a smartphone in a cellular coverage gap on Earth. AST SpaceMobile is one of many companies racing to capture the surging demand for global broadband connectivity. "At the moment, there are 18 constellations that we know are planned all over the world," Dr. Eggl said. "The total number of satellites is a stunning half a million that people are planning to put up there. This is 100 times more than we already have."

AST SpaceMobile made BlueWalker 3's array so large in order to beam strong cellular coverage directly to phones on Earth. The satellite is made of many small antennas that can connect existing smartphones, which is an approach that distinguishes the company from Starlink and other planned constellations that currently rely on ground antennas or dishes. [...] AST SpaceMobile said that it was working with astronomers on techniques to reduce disruptions. It also contrasted the number in its constellation with the tens of thousands planned by other companies. The spokesperson said it could "provide substantial global coverage with around 90 satellites." Though BlueBird satellites would be far fewer in number, they are at least 64 times as big and bright as a Starlink satellite. The SpaceX orbiters are also brightest in the days after their deployment, but they become much fainter once they settle into their target orbits. Astronomers expect that the BlueBird satellites will remain bright in the sky throughout most of their lifetime. As a consequence, one of these satellites could interfere with data captured by astronomical observatories.

NASA Plans To Build Houses On the Moon By 2040 (forbes.com.au) 100

Several scientists from NASA told the New York Times that the agency is planning to build houses on the moon by 2040. Forbes reports: The agency is set to return to the moon and is hoping its astronauts can stay long-term -- in a house built on the moon via a 3D printer. The idea is to build the house structure out of a special lunar concrete from the moon's surface, and NASA has found just the company to do it: Austin-based 3D printing company, ICON. In what's been dubbed Project Olympus, ICON

ICON created its first 350-square-foot prototype home in Austin in March 2018 with a proprietary machine called Vulcan. This year, it showcased its first model home at Wolf Ranch in Georgetown, Texas, which is part of its 3D-printed 100-home community project. The start-up first received funding from NASA in 2020, and in 2022 it announced an additional $60 million for a space-based construction system that can be used beyond earth. The idea is to send a 3D printer up to the moon via a rocket, and the printer completes its job from there.
"We've got all the right people together at the right time with a common goal, which is why I think we'll get there," NASA's director of technology maturation, Niki Werkheiser told The New York Times. "Everyone is ready to take this step together, so if we get our core capabilities developed, there's no reason it's not possible."

James Webb Space Telescope's First Spectrum of a TRAPPIST-1 Planet (phys.org) 28

Tablizer shares a report from Space.com: In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star. Astronomers obtained new data from the James Webb Space Telescope (JWST) on TRAPPIST-1 b, the planet in the TRAPPIST-1 solar system closest to its star. These new observations offer insights into how its star can affect observations of exoplanets in the habitable zone of cool stars. In the habitable zone, liquid water can still exist on the orbiting planet's surface.

The team, which included University of Michigan astronomer and NASA Sagan Fellow Ryan MacDonald, published its study in the journal The Astrophysical Journal Letters. "Our observations did not see signs of an atmosphere around TRAPPIST-1 b. This tells us the planet could be a bare rock, have clouds high in the atmosphere or have a very heavy molecule like carbon dioxide that makes the atmosphere too small to detect," MacDonald said. "But what we do see is that the star is absolutely the biggest effect dominating our observations, and this will do the exact same thing to other planets in the system.

Dish Dealt First-Ever Space-Debris Fine For Misparking Satellite (bloomberg.com) 63

Todd Shields and Loren Grush reporting via Bloomberg: Dish Network Corp. was fined $150,000 by US regulators for leaving a retired satellite parked in the wrong place in space, reflecting official concern over the growing amount of debris orbiting Earth and the potential for mishaps. The Federal Communications Commission called the action its first to enforce safeguards against orbital debris. "This is a breakthrough settlement, making very clear the FCC has strong enforcement authority and capability to enforce its vitally important space debris rules," Loyaan A. Egal, the agency's enforcement bureau chief, said in a statement.

Dish's EchoStar-7 satellite, which relayed pay-TV signals, ran short of fuel, and the company retired it at an altitude roughly 76 miles (122 kilometers) above its operational orbit. It was supposed to have been parked 186 miles above its operational orbit, the FCC said in an order (PDF). The company admitted it failed to park EchoStar-7 as authorized. It agreed to implement a compliance plan and pay a $150,000 civil penalty, the FCC said.

The Orion Nebula Is Full of Impossible Enigmas That Come in Pairs 25

We have discovered a lot in this universe. Planets that orbit stars at right angles. Forbidden worlds that have cheated death. Space explosions that defy explanation. Yet the cosmos continues to surprise us. The latest spectacle, observed by the James Webb Space Telescope, is an agglomeration of nearly 150 free-floating objects amid the Orion Nebula, not far in mass from Jupiter. From a report: Dozens of these worlds are even orbiting each other. The scientists who discovered them have called them Jupiter Mass Binary Objects, or JuMBOs, and the reason for their appearance is a complete mystery. "There's something wrong with either our understanding of planet formation, star formation -- or both," said Samuel Pearson, a scientist at the European Space Agency who worked on the observations that were shared on Monday, which have not yet been peer reviewed. "They shouldn't exist."

The Orion Nebula is a region of star formation 1,350 light-years from Earth, located in the belt of the northern hemisphere constellation of Orion. It has long been studied by astronomers, but the scientists involved in the new Webb telescope study of the area, also released on Monday, say the new images are "by far" the best views yet. "We have better than Hubble resolution but now in the infrared," said Mark McCaughrean, a senior adviser for science and exploration at the ESA. He said the latest observations revealed reams of star formation and fledgling planetary systems in a manner never seen before.

Could 'The Creator' Change Hollywood Forever? (indiewire.com) 96

At the beginning of The Creator a narrator describes AI-powered robots that are "more human than human." From the movie site Looper: It's in reference to the novel "Do Androids Dream of Electric Sheep?" by Philip K. Dick, which was adapted into the seminal sci-fi classic, "Blade Runner." The phrase is used as the slogan for the Tyrell Corporation, which designs the androids that take on lives of their own. The saying perfectly encapsulates the themes of "Blade Runner" and, by proxy, "The Creator." If a machine of sufficient intelligence is indistinguishable from humans, then shouldn't it be considered on equal footing as humanity?
The Huffington Post calls its "the pro-AI movie we don't need right now" — but they also praise it as "one of the most astonishing sci-fi theatrical experiences this year." Variety notes the film was co-written and directed by Gareth Edwards (director of the 2014 version of Godzilla and the Star Wars prequel Rogue One), working with Oscar-winning cinematographer Greig Fraser (Dune) after the two collaborated on Rogue One. But what's unique is the way they filmed it: adding visual effects "almost improvisationally afterward.

"Achieving this meant shooting sumptuous natural landscapes in far-flung locales like Thailand or Tibet and building futuristic temples digitally in post-production..."

IndieWire gushes that "This movie looks fucking incredible. To a degree that shames most blockbusters that cost three times its budget." They call it "a sci-fi epic that should change Hollywood forever." Once audiences see how "The Creator" was shot, they'll be begging Hollywood to close the book on blockbuster cinema's ugliest and least transportive era. And once executives see how much (or how little) "The Creator" was shot for, they'll be scrambling to make good on that request as fast as they possibly can.

Say goodbye to $300 million superhero movies that have been green-screened within an inch of their lives and need to gross the GDP of Grenada just to break even, and say hello — fingers crossed — to a new age of sensibly budgeted multiplex fare that looks worlds better than most of the stuff we've been subjected to over the last 20 years while simultaneously freeing studios to spend money on the smaller features that used to keep them afloat. Can you imagine...? How ironic that such fresh hope for the future of hand-crafted multiplex entertainment should come from a film so bullish and sanguine at the thought of humanity being replaced by A.I [...]

The real reason why "The Creator" is set in Vietnam (and across large swaths of Eurasia) is so that it could be shot in Vietnam. And in Thailand. And in Cambodia, Nepal, Indonesia, and several other beautiful countries that are seldom used as backdrops for futuristic science-fiction stories like this one. This movie was born from the visual possibilities of interpolating "Star Wars"-like tech and "Blade Runner"-esque cyber-depression into primordially expressive landscapes. Greig Fraser and Oren Soffer's dusky and tactile cinematography soaks up every inch of what the Earth has to offer without any concession to motion capture suits or other CGI obstructions, which speaks to the truly revolutionary aspect of this production: Rather than edit the film around its special effects, Edwards reverse-engineered the special effects from a completed edit of his film... Instead of paying a fortune to recreate a flimsy simulacrum of our world on a computer, Edwards was able to shoot the vast majority of his movie on location at a fraction of the price, which lends "The Creator" a palpable sense of place that instantly grounds this story in an emotional truth that only its most derivative moments are able to undo... [D]etails poke holes in the porous border that runs between artifice and reality, and that has an unsurprisingly profound effect on a film so preoccupied with finding ghosts in the shell. Can a robot feel love? Do androids dream of electric sheep? At what point does programming blur into evolution...?

[T]he director has a classic eye for staging action, that he gives his movies room to breathe, and that he knows that the perfect "Kid A" needle-drop (the album, not the song) can do more for a story about the next iteration of "human" life than any of the tracks from Hans Zimmer's score... [T]here's some real cognitive dissonance to seeing a film that effectively asks us to root for a cuter version of ChatGPT. But Edwards and Weitz's script is fascinating for its take on a future in which people have programmed A.I. to maintain the compassion that our own species has lost somewhere along the way; a future in which technology might be a vessel for humanity rather than a replacement for it; a future in which computers might complement our movies rather than replace our cameras.

Will EVs Send OPEC Into a Death Spiral? (telegraph.co.uk) 206

This week the UK's conservative Daily Telegraph newspaper published an interesting perspective from their world economy editor.

"Saudi and OPEC officials self-evidently do not believe their own claim that world oil demand will keep growing briskly for another generation as if electric vehicles had never been invented, and there was no such thing as the Paris Accord." OPEC had to slash output last October in order to shore up prices. It had to cut again in April. The Saudis then stunned traders with a unilateral cut of one million barrels a day (b/d) in June. All told, the OPEC-Russia cartel has had to take 2m b/d of production off the table at a high point in the economic cycle, after China's post-Covid reopening and at a time when the US economy has been running hot with a fiscal expansion roughly equal to Roosevelt's world war budget.

That 2m b/d figure happens to be more or less the amount of crude currently being displaced by EV sales worldwide, according to Bloomberg New Energy Finance.

Yet the mood was all defiance and plucky insouciance at the 24th World Petroleum Congress in Calgary this month... This skips over the awkward detail that EVs are already on track to reach 60pc of total car sales in the world's biggest car market within two years (not a misprint). The cartel is being hit from two sides. Petrol and diesel cars are becoming more efficient, gradually displacing 1.4bn vintage models disappearing into the scrap yard. BP says that alone will cut up to a tenth global oil demand by 2040. With a lag, EVs are now starting to take a material bite, with an S-curve trajectory likely to go parabolic this decade.

China's EVs sales hit 38pc this summer, even though subsidies have mostly been scrapped. This is far ahead of schedule under Beijing's New Energy Vehicle Industry Development Plan. China's Chebai think tank says the emerging consensus is that EV sales will hit 17m or 60pc of total Chinese share by 2025, rising to 90pc by 2030, assuming that the grid can keep up... Vietnam is a few years behind but with similar ambitions. Its EV start-up, VinFast Auto, became the world's third most valuable carmaker after it launched on Nasdaq last month, briefly worth as much as the German car industry before the share price came back down to earth...

OPEC's central premise has long been that the rise of a billion-strong middle class in emerging Asia will more than offset declining oil use in the OECD bloc. That notion is 'withering under scrutiny'... The International Energy Agency (IEA) says global oil demand will peak at 105.5m b/d in 2028 and then flatten for a few years before going into decline... The IEA pulls its punches. The Rocky Mountain Institute argues in its latest report — End of the ICE Age — that half of global car sales could be EVs by 2026, reaching 86pc later this decade.

The article closes by citing "the breathtaking pace of global electrification. The decline of oil in car and bus transport may be closer than almost anybody imagined. OPEC as we know it may be on the cusp of a death spiral."

Mosquitoes Are a Growing Public Health Threat, Reversing Years of Progress (yahoo.com) 89

The New York Times reports that a "squadron of young scientists and an army of volunteers" are "waging an all-out war on a creature that threatens the health of more people than any other on earth: the mosquito." They are testing new insecticides and ingenious new ways to deliver them. They are peering in windows at night, watching for the mosquitoes that home in on sleeping people. They are collecting blood — from babies, from moto-taxi drivers, from goat herders and from their goats — to track the parasites the mosquitoes carry. But Eric Ochomo, the entomologist leading this effort on the front lines of global public health, stood recently in the swampy grass, laptop in hand, and acknowledged a grim reality: "It seems as though the mosquitoes are winning."

Less than a decade ago, it was the humans who appeared to have gained the clear edge in the fight — more than a century old — against the mosquito. But over the past few years, that progress has not only stalled, it has reversed. The insecticides used since the 1970s, to spray in houses and on bed nets to protect sleeping children, have become far less effective; mosquitoes have evolved to survive them. After declining to a historic low in 2015, malaria cases and deaths are rising... This past summer, the United States saw its first locally transmitted cases of malaria in 20 years, with nine cases reported, in Texas, Florida and Maryland. "The situation has become challenging in new ways in places that have historically had these mosquitoes, and also at the same time other places are going to face new threats because of climate and environmental factors," Ochomo said...

Malaria has killed more people than any other disease over the course of human history. Until this century, the battle against the parasite was badly one-sided. Then, between 2000 and 2015, malaria cases dropped by one-third worldwide, and mortality decreased by nearly half, because of widespread use of insecticides inside homes, insecticide-coated bed nets and better treatments. Clinical trials showed promise for malaria vaccines that might protect the children who make up the bulk of malaria deaths. That success lured new investment and talk of wiping the disease out altogether.

But malaria deaths, which fell to a historic low of about 575,000 in 2019, rose significantly over the next two years and stood at 620,000 in 2021, the last year for which there is global data.

NASA Opens OSIRIS-REx's Asteroid-Sample Canister (space.com) 21

Mike Wall writes via Space.com: OSIRIS-REx's asteroid-sample canister just creaked open for the first time in more than seven years. Scientists at NASA's Johnson Space Center (JSC) in Houston lifted the canister's outer lid on Tuesday (Sept. 26), two days after OSIRIS-REx's return capsule landed in the desert of northern Utah. "Scientists gasped as the lid was lifted," NASA's Astromaterials Research and Exploration Science (ARES) division, which is based at JSC, wrote Tuesday in a post on X (formerly Twitter). The operation revealed "dark powder and sand-sized particles on the inside of the lid and base," they added.

That powder once resided on the surface of an asteroid named Bennu, the focus of the OSIRIS-REx mission. OSIRIS-REx launched toward the 1,650-foot-wide (500 meters) Bennu in September 2016, arrived in December 2018 and snagged a hefty sample from the space rock in October 2020 using its Touch-and-Go Sample Acquisition Mechanism, or TAGSAM. The asteroid material landed in Utah inside OSIRIS-REx's return capsule on Sunday (Sept. 24), then made its way to Houston by plane on Monday (Sept. 25). It will be stored and curated at JSC, where the team will oversee its distribution to scientists around the world.

Researchers will study the sample for decades to come, seeking insights about the the solar system's formation and early evolution, as well as the role that carbon-rich asteroids like Bennu may have played in seeding Earth with the building blocks of life. But that work isn't ready to begin; the ARES team hasn't even accessed the main asteroid sample yet. Doing so requires disassembly of the TAGSAM apparatus, an intricate operation that will take considerable time.

Top Chinese Scientist Questions India's Claim To Reaching Moon's South Pole (time.com) 91

Last month, India became the first country to put a spacecraft near the lunar south pole -- breaking China's record for the southernmost lunar landing. Now, the so-called father of China's lunar exploration program, Ouyang Ziyuan, said claims about the accomplishment are overstated. Time reports: Ziyuan [...] told the Chinese-language Science Times newspaper that the Chandrayaan-3 landing site, at 69 degrees south latitude, was nowhere close to the pole, defined as between 88.5 and 90 degrees. On Earth, 69 degrees south would be within the Antarctic Circle, but the lunar version of the circle is much closer to the pole.

"It's wrong!" he said of claims for an Indian polar landing. "The landing site of Chandrayaan-3 is not at the lunar south pole, not in the lunar south pole region, nor is it near the lunar south pole region." The Chandrayaan-3 was 619 kilometers (385 miles) distant from the polar region, Ouyang said.

First Evidence of Spinning Black Hole Detected by Scientists 20

Astronomers have captured the first direct evidence of a black hole spinning, providing new insights into the universe's most enigmatic objects. From a report: The observations focus on the supermassive black hole at the centre of the neighbouring Messier 87 galaxy, whose shadow was imaged by the Event Horizon Telescope. Like many supermassive black holes, M87 features powerful jets that are launched from the poles at close to the speed of light into intergalactic space. Scientists have predicted that the rotation of a black hole powers these cosmic jets, but until now direct evidence was elusive.

"After the success of black hole imaging in this galaxy with the Event Horizon Telescope, whether this black hole is spinning or not has been a central concern among scientists," said Dr Kazuhiro Hada, of the national astronomical observatory of Japan and co-author. "Now anticipation has turned into certainty. This monster black hole is indeed spinning." M87 is located 55m light years from the Earth and harbours a black hole 6.5bn times more massive than the Sun. Just beyond the black hole is an accretion disk of gas and dust, swirling on the precipice of the cosmic sinkhole. Some of this material is destined to fall into the black hole, disappearing for ever. But a fraction will be ejected out from the poles of the black hole at more than 99.99% of the speed of light.

Bids For ISS Demolition Rights Are Now Open, NASA Declares 102

Jude Karabus writes via The Register: NASA has confirmed it will ask American companies to duke it out for the opportunity to deorbit the International Space Station -- quietly releasing a request for proposals last week. The specs, which appeared on U.S. government e-procurement portal SAM.gov, are for a vehicle the agency has dubbed the U.S. Deorbit Vehicle (USDV), which will be focused on the space station's final deorbit activity. According to NASA, it will be a "new spacecraft design or modification to an existing spacecraft" that must function on its first flight (yep, important that), as well as have "sufficient redundancy and anomaly recovery capability to continue the critical deorbit burn."

NASA is getting in well ahead of the 2030 deadline, by which time the agency is hoping to have "seamlessly transitioned" to commercially owned and operated platforms in low Earth orbit (LEO). The vehicle will take years to develop, test, and certify. The request for proposals (RFP) is a confirmation that the agency is going to go with the second option it floated in March, saying a private contractor would cut costs down from a predicted $1 billion.
