An anonymous reader quotes a report from The Guardian: More than 1,000 "super-emitter" sites gushed the potent greenhouse gas methane into the global atmosphere in 2022, the Guardian can reveal, mostly from oil and gas facilities. The worst single leak spewed the pollution at a rate equivalent to 67m running cars. Separate data also reveals 55 "methane bombs" around the world -- fossil fuel extraction sites where gas leaks alone from future production would release levels of methane equivalent to 30 years of all US greenhouse gas emissions.

Methane emissions cause 25% of global heating today and there has been a "scary" surge since 2007, according to scientists. This acceleration may be the biggest threat to keeping below 1.5C of global heating and seriously risks triggering catastrophic climate tipping points, researchers say. The two new datasets identify the sites most critical to preventing methane-driven disaster, as tackling leaks from fossil fuel sites is the fastest and cheapest way to slash methane emissions. Some leaks are deliberate, venting the unwanted gas released from underground while drilling for oil into the air, and some are accidental, from badly maintained or poorly regulated equipment.

Fast action would dramatically slow global heating as methane is short-lived in the atmosphere. An emissions cut of 45% by 2030, which the UN says is possible, would prevent 0.3C of temperature rise. Methane emissions therefore present both a grave threat to humanity, but also a golden opportunity to decisively act on the climate crisis. [...] The methane super-emitter sites were detected by analysis of satellite data, with the US, Russia and Turkmenistan responsible for the largest number from fossil fuel facilities. The biggest event was a leak of 427 tonnes an hour in August, near Turkmenistan's Caspian coast and a major pipeline. That single leak was equivalent to the rate of emissions from 67m cars, or the hourly national emissions of France. Future methane emissions from fossil fuel sites -- the methane bombs -- are also forecast to be huge, threatening the entire global "carbon budget" limit required to keep heating below 1.5C. More than half of these fields are already in production, including the three biggest methane bombs, which are all in North America.

America's public health-protecting Food and Drug Administration wants to update its definition of "healthy" for purposes of product labeling.

But the Washington Post reports dozens of food manufacturers are now "claiming the new standards are draconian and will result in most current food products not making the cut, or in unappealing product reformulations." Under the proposal, manufacturers can label their products "healthy" only if they contain a meaningful amount of food from at least one of the main food groups such as fruit, vegetable or dairy, as recommended by federal dietary guidelines. They must also adhere to specific limits for certain nutrients, such as saturated fat, sodium and added sugars.

It's the added sugar limit that has been the sticking point for many food executives. The FDA's previous rules put limits around saturated fat and sodium but did not include limits on added sugars.

The Consumer Brands Association, which represents 1,700 major food companies from General Mills to Pepsi, wrote a 54-page comment to the FDA in which it stated the proposed rule was overly restrictive and would result in a framework that would automatically disqualify a vast majority of packaged foods.... The proposed rule, if finalized, they said, would violate the First Amendment rights of food companies and could harm both consumers and manufacturers. The Sugar Association has an issue with the added sugar limit; Campbell Soup is more focused on that sodium....

Virtually every part of the food industry appeared disgruntled (here are the 402 comments about the proposed rule). Baby food company Happy Family Organics said the proposed rule probably would lead to an unintended exclusion of some nutrient-rich products. And the American Cheese Society took a more philosophical approach, saying the word "healthy" isn't that helpful on a label and should be used in a complete diet or lifestyle context rather than in a nutrient or single food-focused context.
The FDA estimates that up to just 0.4% of people who try to follow their guidelines would be swayed by the word "healthy" in their long-term food-purchasing decisions, according to the article. It's a position supported by a research paper in the Journal of Public Policy and Marketing analyzing hundreds of international studies on the effectiveness of front-of-package nutrition labeling.

"The authors found that the most effective means of conveying nutrition information is a graphic warning label, as has been adopted in Chile, Peru, Uruguay, Mexico and Israel. In Chile, black warning labels shaped like stop signs are required for packaged food and drinks that exceed, per 100 grams: 275 calories, 400 milligrams of sodium, 10 grams of sugar or four grams of saturated fats."

An anonymous readers this surprising story from Mashable: When a Russian spaceship docked as a lifeboat for three stranded men at the International Space Station in February, one may have wondered if Sergei Krikalev, heading the rescue mission, felt any deja vu.

If that name doesn't ring a bell, he's also sometimes known as "the last Soviet" for his more than 311 days spent in space as the Soviet Union collapsed 250 miles beneath him in 1991. He was only meant to be at the Mir station for five months. Instead, he remained for close to a year, never abandoning the outpost.

Today, Krikalev, the former cosmonaut, is the executive director of human spaceflight for the Russian space agency. That means it's on his watch to make sure NASA astronaut Frank Rubio and cosmonauts Sergey Prokopyev and Dmitry Petelin get back home safely after their ship sprang a leak at the station in December 2022. The three marooned crew members were supposed to return this month. But their mission will now stretch for a year, until a new crew arrives to relieve them on a separate spacecraft in six months.

Krikalev's story of being stranded in space is now getting a perhaps overdue spotlight with a new podcast series called "The Last Soviet." And it's being told by another cosmonaut, Lance Bass.... Few may remember that boy-band member Bass almost made it to space on a Soyuz spacecraft himself. In 2002, he spent about six months, off and on, training in Star City, Russia, and was certified by Russia and NASA to fly a mission to the space station.

The New York Times reports: After the disaster at the nuclear power plant in Chernobyl, Ukraine, in 1986, local residents were forced to permanently evacuate, leaving behind their homes and, in some cases, their pets. Concerned that these abandoned animals might spread disease or contaminate humans, officials tried to exterminate them.

And yet, a population of dogs somehow endured. They found fellowship with Chernobyl cleanup crews, and the power plant workers who remained in the area sometimes gave them food. (In recent years, adventurous tourists have dispensed handouts, too.) Today, hundreds of free-ranging dogs live in the area around the site of the disaster, known as the exclusion zone. They roam through the abandoned city of Pripyat and bed down in the highly contaminated Semikhody train station.

Now, scientists have conducted the first deep dive into the animals' DNA. The dogs of Chernobyl are genetically distinct, different from purebred canines as well as other groups of free-breeding dogs, the scientists reported Friday in Science Advances. It remains too soon to say whether, or how, the radioactive environment has contributed to the unique genetic profiles of the dogs of Chernobyl, the scientists said. But the study is the first step in an effort to understand not only how long-term radiation exposure has affected the dogs but also what it takes to survive an environmental catastrophe.

"Do they have mutations that they've acquired that allow them to live and breed successfully in this region?" said Elaine Ostrander, a dog genomics expert at the National Human Genome Research Institute and a senior author of the study. "What challenges do they face and how have they coped genetically?"

The United Nations Environment Program (UNEP) is investigating the potentials and dangers of solar geoengineering technologies, stating that these controversial interventions are humanity's "only option" to quickly cool the planet within years. An anonymous shares an excerpt from a Motherboard article: In a report published by UNEP in February, an independent panel describes what's currently known about so-called solar radiation modification, also called solar geoengineering, and concludes that, despite its great potential, it's not viable or even safe right now. Nonetheless, amid growing calls from governments to find an emergency brake for climate change -- and ongoing, independent efforts to develop solar geoengineering technology -- the UNEP is calling for a full-scale global review of the tech and eventual multinational framework for how it should be governed. The recommendations have some opponents fearing that this amounts to endorsement of adopting the technology -- a move that could create an even worse environmental crisis by messing with intertwined natural climate systems or pulling the focus away from mitigation measures, as well as further widening the inequalities that already exist as a result of climate change.

Solar radiation modification describes a range of technologies that aim to cool our overheated planet by reflecting incoming sunlight back out into space, or making it easier for heat coming off the earth to escape. Blocking out just two percent of sunlight could, according to some estimates, totally offset the warming that comes from doubling the amount of CO2 in the atmosphere from pre-industrial levels. It's a tantalizing prospect, but comes with a raft of issues. For one, as the report notes, the best large-scale evidence we have that it could even work is from volcanic eruptions, where the smog cooled the globe for a couple of years afterwards. Most of the actual research has involved climate modeling, theoretical analyses or cost estimates. Some groups have conducted small-scale indoor experiments of how the tech might work. No one's taken the trials outdoors yet.

Even if we knew more, it's not a be-all-end-all climate solution, said UNEP's chief scientist, Andrea Hinwood. "SRM technologies, should they be considered at some point in the future, do not solve the climate crisis because they do not reduce greenhouse gas emissions nor reverse the impacts of climate change. The world must be crystal clear on this point," she said in a UN media release. What solar geoengineering might do though, is buy the planet some time. The UNEP report highlights that even if we fully halted CO2 emissions right now, it could take at least until the end of the century to see a drop in temperature. "Make no mistake: there are no quick fixes to the climate crisis," wrote UNEP executive director Inger Andersen in the report. "Increased and urgent action to slash greenhouse gas emissions and invest in adapting to the impacts of climate change is immutable. Yet current efforts remain insufficient." Despite firm opposition from some, the message from the UNEP report seems to be to proceed with caution. "While UNEP is concerned, it is naive to think research will cease and the issues will disappear. We cannot afford to bury our heads in the sand," said chief scientist Hinwood.

With more lunar missions than ever on the horizon, the European Space Agency wants to give the moon its own time zone. The Associated Press reports: This week, the agency said space organizations around the world are considering how best to keep time on the moon. The idea came up during a meeting in the Netherlands late last year, with participants agreeing on the urgent need to establish "a common lunar reference time," said the space agency's Pietro Giordano, a navigation system engineer. "A joint international effort is now being launched towards achieving this," Giordano said in a statement.

For now, a moon mission runs on the time of the country that is operating the spacecraft. European space officials said an internationally accepted lunar time zone would make it easier for everyone, especially as more countries and even private companies aim for the moon and NASA gets set to send astronauts there. [...] The international team looking into lunar time is debating whether a single organization should set and maintain time on the moon, according to the European Space Agency.

There are also technical issues to consider. Clocks run faster on the moon than on Earth, gaining about 56 microseconds each day, the space agency said. Further complicating matters, ticking occurs differently on the lunar surface than in lunar orbit. Perhaps most importantly, lunar time will have to be practical for astronauts there, noted the space agency's Bernhard Hufenbach. "This will be quite a challenge" with each day lasting as long as 29.5 Earth days, Hufenbach said in a statement. "But having established a working time system for the moon, we can go on to do the same for other planetary destinations."

An anonymous reader quotes a report from Motherboard: At least two companies in British Columbia, Canada, say they've received exemptions from the federal government allowing them to produce and distribute cocaine, heroin, MDMA, or magic mushrooms. But it's not clear under what circumstances the companies will be able to sell the drugs, and B.C. Premier David Eby said he was "astonished" to hear the announcement. On Thursday, Sunshine Earth Labs, a psychedelics manufacturer announced that Health Canada, a federal government agency, is allowing the company to legally produce and distribute the coca leaf and cocaine; MDMA; opium; morphine, heroin and psilocybin, the active ingredient in shrooms. The company said it plans to "bring a safer supply of drugs to the global market."

Meanwhile, cannabis extractions company Adastra announced it's now legally allowed to both produce and distribute psilocybin and cocaine. In a statement to VICE News, Health Canada said Adastra is licensed to produce the drugs for scientific and medical purposes but cannot sell products to the general public. "They are only permitted for sale to other licence holders who have cocaine listed on their licence, pharmacists, practitioners, hospitals, or the holder of a section 56(1) exemption for research purposes," the agency said.

Both companies claim they received amendments under Health Canada's Dealer's Licenses, which grant manufacturers, doctors, and researchers exemptions to the Controlled Drugs and Substances Act, allowing them to legally possess and make banned drugs. In a news conference, Eby said the licenses were granted without consultation from the province. "It is not part of our provincial plan," he said, noting that he would be following up with Health Canada about the announcements. Adastra said it's license allows it to "interact with up to 250 grams of cocaine and to import coca leaves to manufacture and synthesize the substance."

A new disease caused solely by plastics has been discovered in seabirds. The birds identified as having the disease, named plasticosis, have scarred digestive tracts from ingesting waste, scientists at the Natural History Museum in London say. From a report: It is the first recorded instance of specifically plastic-induced fibrosis in wild animals, researchers say. Plastic pollution is becoming so prevalent that the scarring was widespread across different ages of birds, according to the study, published in the Journal of Hazardous Materials. Young birds were found to have the disease, and it is thought chicks were being fed the plastic pollution by parents accidentally bringing it back in food. Scientists, including the Natural History Museum's Dr Alex Bond and Dr Jennifer Lavers, studied flesh-footed shearwaters from Australia's Lord Howe Island to look at the relationship between levels of ingested plastic and the proventriculus organ -- the first part of a bird's stomach. They found that the more plastic a bird had ingested, the more scarring it had. The disease can lead to the gradual breakdown of tubular glands in the proventriculus. Losing these glands can cause the birds to become more vulnerable to infection and parasites and affect their ability to digest food and absorb some vitamins.

MIT Technology Review has revealed two cases in which babies conceived with the three-parent baby technique have shown what scientists call "reversion." "In both cases, the proportion of mitochondrial genes from the child's mother has increased over time, from less than 1% in both embyros to around 50% in one baby and 72% in another," they report. From the report: When the first baby born using a controversial procedure that meant he had three genetic parents was born back in 2016, it made headlines. The baby boy inherited most of his DNA from his mother and father, but he also had a tiny amount from a third person. The idea was to avoid having the baby inherit a fatal illness. His mother carried genes for a disease in her mitochondria. Swapping these with genes from a donor -- a third genetic parent -- could prevent the baby from developing it. The strategy seemed to work. Now clinics in other countries, including the UK, Greece, and Ukraine, are offering the same treatment. It was made legal in Australia last year. But it might not always be successful. [...]

Fortunately, both babies were born to parents without genes for mitochondrial disease; they were using the technique to treat infertility. But the scientists behind the work believe that around one in five babies born using the three-parent technique could eventually inherit high levels of their mothers' mitochondrial genes. For babies born to people with disease-causing mutations, this could spell disaster -- leaving them with devastating and potentially fatal illness. The findings are making some clinics reconsider the use of the technology for mitochondrial diseases, at least until they understand why reversion is happening. "These mitochondrial diseases have devastating consequences," says Bjorn Heindryckx at Ghent University in Belgium, who has been exploring the treatment for years. "We should not continue with this." "It's dangerous to offer this procedure [for mitochondrial diseases]," says Pavlo Mazur, an embryologist based in Kyiv, Ukraine, who has seen one of these cases firsthand.

Britain's failed attempt to send satellites into orbit was a "disaster" and MPs are being urged to redirect funding to hospitals, with the country now seen as "toxic" for future launches. The Guardian reports: Senior figures at the Welsh company Space Forge, which lost a satellite when Virgin Orbit's Start Me Up mission failed to reach orbit, said a "seismic change" was needed for the UK to be appealing for space missions. Lengthy delays by the Civil Aviation Authority (CAA), as well as the launch failure, had left Space Forge six months behind its competition in the race to be the first company to bring a satellite back down to Earth, when it had been six months ahead, the science and technology committee heard.

Patrick McCall, a non-executive director at Space Forge, said: "The CAA is taking a different approach to risk, and a bit to process and timing as well. But I think unless there is, without wanting to be too dramatic, a seismic change in that approach, the UK is not going to be competitive from a launch perspective. I think the conclusion I've reached is right now it's not a good use of money, because our regulatory framework is not competitive." He added that the UK ought to consider spending the money it was investing in launch capability on other areas, such as hospitals.

Greg Clark, the chair of the committee, said it was a "disaster" that an attempt to show what the UK was capable of had turned "toxic for a privately funded launch." "We had the first attempted launch but the result is that you as an investor in space are saying there is no chance of investors supporting another launch from the UK with the current regulator conditions." Dan Hart, the CEO of Virgin Orbit, told MPs he had expected the CAA to work more similarly to the Federal Aviation Authority in the US but he had found the UK regulator more conservative. The company has since ended its contract with Spaceport Cornwall at Newquay airport but said it was still hoping to launch from the site in the future. Sir Stephen Hillier, the chair of the CAA, said: "Our primary duty is to ensure that the space activity in the UK is conducted safely. The CAA licensed in advance of technical readiness."

An anonymous reader quotes a report from The Guardian: More than half of the world's population will be overweight or obese by 2035 unless governments take decisive action to curb the growing epidemic of excess weight, a report has warned. About 2.6 billion people globally -- 38% of the world population -- are already overweight or obese. But on current trends that is expected to rise to more than 4 billion people (51%) in 12 years' time, according to research by the World Obesity Federation.

Without widespread use of tactics such as taxes and limits on the promotion of unhealthy food, the number of people who are clinically obese will increase from one in seven today to one in four by 2035. If that happens, almost 2 billion people worldwide would be living with obesity. Those with a body mass index (BMI) of 25 are judged to be overweight, while people whose BMI is at least 30 are deemed to be obese. Evidence shows that obesity increases someone's risk of cancer, heart disease and other diseases.

Obesity among children and young people is on course to increase faster than among adults. By 2035 it is expected to be at least double the rate seen in 2020, according to the federation's latest annual World Obesity Atlas report. It is expected to rise by 100% among boys under 18, leaving 208 million affected, but go up even more sharply -- by 125% -- among girls the same age, which would see 175 million of them affected. [...] The federation's report also highlights that many of the world's poorest countries are facing the sharpest increases in obesity yet are the least well prepared to confront the disease. Nine of the 10 countries set to experience the biggest rises in coming years are low- or middle-income nations in Africa and Asia. "The global cost of obesity is also due to rocket, from $1.96 trillion in 2019 to $4.32 trillion by 2035, which would be the equivalent of 3% of global GDP -- a sum comparable to the economic damage wrought by Covid-19 -- the federation estimates," adds the report.

According to Reuters, Elon Musk's medical device company, Neuralink, was denied permission last year to begin human trials of a revolutionary brain implant to treat intractable conditions such as paralysis and blindness. The U.S. Food and Drug Administration (FDA) outlined dozens of issues the company must address before human testing can begin, according to seven current and former employees. From the report: The agency's major safety concerns involved the device's lithium battery; the potential for the implant's tiny wires to migrate to other areas of the brain; and questions over whether and how the device can be removed without damaging brain tissue, the employees said. A year after the rejection, Neuralink is still working through the agency's concerns. Three staffers said they were skeptical the company could quickly resolve the issues -- despite Musk's latest prediction at a Nov. 30 presentation that the company would secure FDA human-trial approval this spring.

Neuralink has not disclosed details of its trial application, the FDA's rejection or the extent of the agency's concerns. As a private company, it is not required to disclose such regulatory interactions to investors. During the hours-long November presentation, Musk said the company had submitted "most of our paperwork" to the agency, without specifying any formal application, and Neuralink officials acknowledged the FDA had asked safety questions in what they characterized as an ongoing conversation. Such FDA rejections do not mean a company will ultimately fail to gain the agency's human-testing approval. But the agency's pushback signals substantial concerns, according to more than a dozen experts in FDA device-approval processes.

The rejection also raises the stakes and the difficulty of the company's subsequent requests for trial approval, the experts said. The FDA says it has approved about two-thirds of all human-trial applications for devices on the first attempt over the past three years. That total rose to 85% of all requests after a second review. But firms often give up after three attempts to resolve FDA concerns rather than invest more time and money in expensive research, several of the experts said. Companies that do secure human-testing approval typically conduct at least two rounds of trials before applying for FDA approval to commercially market a device.

For the first time researchers have proven a clear correlation between deforestation and regional precipitation. Scientists hope it may encourage agricultural companies and governments in the Amazon and Congo basin regions and south-east Asia to invest more in protecting trees and other vegetation. From a report: The study found that the more rainforests are cleared in tropical countries, the less local farmers will be able to depend on rain for their crops and pastures. The paper, published in the journal Nature, adds to fears that the degradation of the Amazon is approaching a tipping point after which the rainforest will no longer be able to generate its own rainfall and the vegetation will dry up. People living in deforested areas have long provided anecdotal evidence that their microclimates became drier with lower tree cover. Scientists already knew that killing trees reduces evapotranspiration and thus theorised this would result in lower local rainfall.

The team at Leeds University have now proven this using satellite and meteorological records from 2003-17 across pantropical regions. Even at a small scale, they found an impact, but the decline became more pronounced when the affected area was greater than 50km squared (2,500 sq km). At the largest measured scale of 200km squared (40,000 sq km), the study discovered rainfall was 0.25 percentage points lower each month for every 1 percentage point loss of forest. This can enter into a vicious cycle, as reductions in rainfall lead to further forest loss, increased fire vulnerability and weaker carbon drawdown. One of the authors, Prof Dominick Spracklen of the University of Leeds, said 25% to 50% of the rain that fell in the Amazon came from precipitation recycling by the trees. Although the forest is sometimes described as the "lungs of the world," it functions far more like a heart that pumps water around the region.

Australia is preparing for its next step away from fossil fuels by creating a market to replace the spinning coal plant turbines that help stabilize the power grid. From a report: The government's adviser on energy policy, the Australian Energy Market Commission, is consulting on a rule change for a spot market in inertia provision, it said in a statement on Thursday. Australia's world-leading usage of wind, solar and batteries has led to "new and previously unobserved operational conditions," it said.

Conventional power plants use turbines that keep revolving even when the fuel that's forcing them to move stops burning. It's a process known as inertia, which helps network operators maintain stability, smooth over disturbances in the grid and prevent blackouts. However, solar panels and wind turbines generally stop and start almost instantaneously -- hence the AEMC's call for other sources of inertia.

After analyzing the data collected from NASA's successful Double Asteroid Redirection Test (DART) last year, the DART team found that the kinetic impactor mission "can be effective in altering the trajectory of an asteroid, a big step toward the goal of preventing future asteroid strikes on Earth." The findings were published in four papers in the journal Nature. From a NASA press release: The first paper reports DART's successful demonstration of kinetic impactor technology in detail: reconstructing the impact itself, reporting the timeline leading up to impact, specifying in detail the location and nature of the impact site, and recording the size and shape of Dimorphos. The authors, led by Terik Daly, Carolyn Ernst, and Olivier Barnouin of APL, note DART's successful autonomous targeting of a small asteroid, with limited prior observations, is a critical first step on the path to developing kinetic impactor technology as a viable operational capability for planetary defense. Their findings show intercepting an asteroid with a diameter of around half a mile, such as Dimorphos, can be achieved without an advance reconnaissance mission, though advance reconnaissance would give valuable information for planning and predicting the outcome. What is necessary is sufficient warning time -- several years at a minimum, but preferably decades. "Nevertheless," the authors state in the paper, DART's success "builds optimism about humanity's capacity to protect the Earth from an asteroid threat."

The second paper uses two independent approaches based on Earth-based lightcurve and radar observations. The investigation team, led by Cristina Thomas of Northern Arizona University, arrived at two consistent measurements of the period change from the kinetic impact: 33 minutes, plus or minus one minute. This large change indicates the recoil from material excavated from the asteroid and ejected into space by the impact (known as ejecta) contributed significant momentum change to the asteroid, beyond that of the DART spacecraft itself. The key to kinetic impact is that the push to the asteroid comes not only from colliding spacecraft, but also from this ejecta recoil. The authors conclude: "To serve as a proof-of-concept for the kinetic impactor technique of planetary defense, DART needed to demonstrate that an asteroid could be targeted during a high-speed encounter and that the target's orbit could be changed. DART has successfully done both."

In the third paper, the investigation team, led by Andrew Cheng of APL, calculated the momentum change transferred to the asteroid as a result of DART's kinetic impact by studying the change in the orbital period of Dimorphos. They found the impact caused an instantaneous slowing in Dimorphos' speed along its orbit of about 2.7 millimeters per second -- again indicating the recoil from ejecta played a major role in amplifying the momentum change directly imparted to the asteroid by the spacecraft. That momentum change was amplified by a factor of 2.2 to 4.9 (depending on the mass of Dimorphos), indicating the momentum change transferred because of ejecta production significantly exceeded the momentum change from the DART spacecraft alone. DART's scientific value goes beyond validating kinetic impactor as a means of planetary defense. By smashing into Dimorphos, the mission has broken new ground in the study of asteroids. DART's impact made Dimorphos an "active asteroid" -- a space rock that orbits like an asteroid but has a tail of material like a comet -- which is detailed in the fourth paper led by Jian-Yang Li of the Planetary Science Institute.

schwit1 shares a report from Ars Technica, written by Eric Berger: One of the world's most important rocket companies, United Launch Alliance, may be sold later this year. The potential sale has not been disclosed publicly, but three sources confirmed to Ars that potential buyers have been contacted about the opportunity. These sources said a deal is expected to be closed before the end of this year and that investment firm Morgan Stanley and consulting firm Bain & Company are managing the transaction.

The sale of United Launch Alliance, or ULA as it is known within the industry, would mark the end of an era that has lasted for nearly two decades. The company was officially formed in 2005 as part of a deal brokered by the US government, ensuring the military had access to both Atlas and Delta rockets to put national security satellites into space. To form ULA, Lockheed Martin and Boeing merged their launch businesses into a single company, each taking a 50 percent stake. This union was profitable for both parent companies, as ULA held a monopoly on launching national security missions and, effectively, NASA science probes. In return for 100 percent mission success, ULA received large launch contracts and an approximately $1 billion annual subsidy from the US Department of Defense to maintain "launch readiness."

The emergence of SpaceX in the early 2010s with the increasingly reliable Falcon 9 rocket started to disrupt this profitable arrangement. SpaceX sold the Falcon 9 rocket at a substantial discount to ULA's Atlas V and Delta IV rockets. The company also successfully sued the US government to allow the Falcon 9 rocket to compete for national security missions, and SpaceX launched its first one in 2017. In recent years, SpaceX has come to dominate United Launch Alliance in terms of cadence. By the end of 2022, the upstart was launching as many rockets each month as ULA launched during a calendar year. During the last four years, in fact, SpaceX has landed more rockets than ULA has launched during its existence. However, ULA still holds a prominent place in the global launch industry, and there will likely be no shortage of suitors.

Longtime Slashdot reader theshowmecanuck shares a report from CBS News: A 2012 trip to a Fayetteville, Arkansas, Walmart to pick up some milk turned out to be one for the history books. A giant bug that stopped a scientist in his tracks as he walked into the store and he ended up taking home turned out to be a rare Jurassic-era flying insect. Michael Skvarla, director of Penn State University's Insect Identification Lab, found the mysterious bug -- an experience that he says he remembers "vividly."

"I was walking into Walmart to get milk and I saw this huge insect on the side of the building," he said in a press release from Penn State. "I thought it looked interesting, so I put it in my hand and did the rest of my shopping with it between my fingers. I got home, mounted it, and promptly forgot about it for almost a decade."

[I]n the fall of 2020 when he was teaching an online course on insect biodiversity and evolution, Skvarla was showing students the bug and suddenly realized it wasn't what he originally thought. He and his students then figured out what it might be -- live on a Zoom call. "We were watching what Dr. Skvarla saw under his microscope and he's talking about the features and then just kinda stops," one of his students Codey Mathis said. "We all realized together that the insect was not what it was labeled and was in fact a super-rare giant lacewing." A clear indicator of this identification was the bug's wingspan. It was about 50 millimeters -- nearly 2 inches -- a span that the team said made it clear the insect was not an antlion. His team's molecular analysis on the bug has been published in the Proceedings of the Entomological Society of Washington.

theshowmecanuck captioned: "To be fair, he said he didn't know what it was so [he] just collected it and took it home, and then figured it out later. My thought that I added to the title was because of this quote in the story (which tickled my cynicism in humanity): "It could have been 100 years since it was even in this area -- and it's been years since it's been spotted anywhere near it..."

An anonymous reader quotes a report from The Guardian: The mysterious set of symptoms known as "Havana syndrome" was not caused by an energy weapon or foreign adversary, US intelligence has concluded. The assessment concludes a multi-year investigation into approximately 1,000 "anomalous health incidents" (AHIs) among US diplomats, spies and other employees in US embassies and missions around the world. Victims reported brain injuries, hearing loss, vertigo and strange auditory sensations, among other symptoms. Many suspected they had been victims of a targeted attack using some kind of directed energy weapon.

Of the seven intelligence agencies that undertook the investigation, five determined that "available intelligence consistently points against the involvement of US adversaries in causing the reported incidents," according to an unclassified version of the report released Wednesday by the House intelligence committee. Those five agencies deemed foreign adversary involvement "very unlikely." One considered it "unlikely" and one declined to state a conclusion.

The assessment involved a painstaking effort to analyze syndrome cases for patterns that could link them, as well as a search, using forensics and geolocation data, for evidence of a directed energy weapon, unnamed officials told the Post. "There was nothing," one official said. The officials told the Post they were open to new evidence that a foreign adversary had developed an energy weapon, but did not believe Russia or any other adversary was involved in these cases. The intelligence agencies "judge that there is no credible evidence that a foreign adversary has a weapon or collection device that is causing AHIs", according to the unclassified report. "In light of this and the evidence that points away from a foreign adversary, causal mechanism, or unique syndrome linked to AHIs, IC agencies assess that symptoms reported by US personnel were probably the result of factors that did not involve a foreign adversary, such as preexisting conditions, conventional illnesses, and environmental factors," the report reads.

Three agencies have "high confidence" in that assessment, three have "moderate confidence" and one has "low confidence."

An anonymous reader quotes a report from CBS News: Erythritol, a zero-calorie sugar substitute used to sweeten low-cal, low-carb and "keto" products, is linked to higher risk of heart attack, stroke and death, according to a new study. Researchers at the Cleveland Clinic studied over 4,000 people in the U.S. and Europe and found those with higher blood erythritol levels were at elevated risk of experiencing these major adverse cardiac events. The research, published Monday in the journal Nature Medicine, also found erythritol made blood platelets easier to form a clot.

"Our study shows that when participants consumed an artificially sweetened beverage with an amount of erythritol found in many processed foods, markedly elevated levels in the blood are observed for days -- levels well above those observed to enhance clotting risks," said Dr. Stanley Hazen, senior author of the study and chairman for the department of cardiovascular and metabolic sciences at Cleveland Clinic, in a press release.

While the study doesn't definitively show causation, CBS News medical contributor Dr. David Agus says there's "certainly enough data to make you very worried." "Most artificial sweeteners bind to your sweet receptors but aren't absorbed. Erythritol is absorbed and has significant effects, as we see in the study," Agus explains. Sweeteners like erythritol have "rapidly increased in popularity in recent years," Hazen noted, and the researchers say more in-depth study is needed to understand their long-term health effects. "Cardiovascular disease builds over time, and heart disease is the leading cause of death globally. We need to make sure the foods we eat aren't hidden contributors," he said. "In the study, researchers looked at the levels of erythritol in the blood of around 4,000 people from the United States and Europe and found that those with the highest blood concentration of the sugar substitute were more likely to have a stroke or heart attack," adds the New York Times in their reporting. "The participants, who mostly were over the age of 60, either already had or were at high risk for cardiovascular diseases because of conditions like diabetes and hypertension."

"The researchers also found that when they fed mice erythritol, that promoted blood clot formation. Erythritol appeared to induce clotting in human blood and plasma as well. Among eight people who consumed erythritol at levels typical in a pint of keto ice cream or a can of an artificially sweetened beverage, the sugar alcohol lingered in their blood for longer than two days."

Dr. Hazen said: "Every way we looked at it, it kept showing the same signal."

Starting today, Google is rolling out fall detection to all Pixel Watches. The Verge reports: Google's version of fall detection is similar to those you'll find on other smartwatches, like the Apple Watch and the Samsung Galaxy Watch 4 and 5 lineups. It uses the device's motion sensors and machine learning to figure out when someone's taken a tumble and might need some help. The feature will purportedly kick in about 30 seconds after it detects a hard fall. At that point, the watch will vibrate, sound an alarm, and flash a notification asking if the Pixel Watch owner needs help. If users don't respond after a minute, the watch will automatically call emergency services and share their location.

According to Google, the Pixel Watch ought to be able to differentiate between a hard fall, stumble, or physical activity that may mimic falling -- like the dreaded burpee. Whether that claim holds water is another matter that we'll have to test for ourselves. [...] The feature is opt in, so you'll have to turn it on manually if it's something you want. Google says Pixel Watch owners may see a promotional card pop up in the Updates page within the Watch Companion app. If you don't see it there, you can also check directly from the wrist in the Personal Safety app.
