Journalist Eric Newcomer, writing at The Free Press: There was a time when I believed that self-driving cars should be held to the standard of airplanes. Every mistake needed to be rigorously understood and any human death was unforgivable. But my view has evolved over time as human drivers have continued to kill tens of thousands of people a year. We need a solution that's meaningfully better than human drivers, yes, but we shouldn't wait for perfection before we start getting dangerous human drivers off the streets.

Lost in all the fulminating about automation and big-tech tyranny is the fact that self-driving cars are an attempt to solve a very serious problem. Traffic fatalities are a leading cause of death in the United States for anyone between the ages of 1 and 54. About 40,000 people die in car crashes a year in the U.S., with about one-third involving drunk drivers. There's a natural, though irrational, human bias toward the status quo. We tend to believe that things are the way they are for a good reason. But of course, technology has drastically improved human lives and human life spans already. Why stop now that more powerful computer chips and sophisticated artificial intelligence models open up new possibilities?

[...] Leaving aside seething hostility toward tech and private capital, and worries over job losses, the most credible objection to self-driving cars from the left is the fear that deploying them means doubling down on roads and sprawl, and undermining support for public transportation projects. But there's no reason self-driving cars and public transportation need to be at odds. They can fulfill different needs. Autonomous vehicles are being deployed in San Francisco in fleets through ride-hailing programs, reducing the need for personal car ownership. If we can get self-driving cars working, self-driving buses on regular routes should be even easier. And contrary to the view that driverless cars are being deployed unilaterally by tech billionaires, the people's representatives -- government officials -- gave Alphabet-owned Waymo a license to operate. Our roads and motor vehicles are tightly regulated. Single incidents have derailed self-driving car projects, from Uber and more recently, GM-owned Cruise, while human drivers kill tens of thousands a year unimpeded.

Robin George Andrews writes via The New York Times: In 2022, when NASA's $325 million spacecraft crashed into an asteroid named Dimorphos at 14,000 miles per hour, cheers and applause erupted back on Earth. NASA's Double Asteroid Redirection Test (DART) mission deliberately targeted Dimorphos to change its orbit around the larger asteroid Didymos as a dress rehearsal of sorts for thwarting a deadly space rock that might someday head toward Earth. The world's first-ever planetary defense experiment was deemed a triumph: The asteroid's orbit shrank by 33 minutes, far above the minimum threshold of 73 seconds. But what the DART team didn't realize then was just how bizarrely Dimorphos responded to that punch. A new study, published on Monday in Nature Astronomy, has concluded that DART hit Dimorphos so hard that the asteroid changed shape.

Simulations of the impact suggest that the spacecraft's death did not excavate a normal, bowl-shaped crater. Instead, it left behind something that resembles a dent. And although the artificial impact blasted millions of tons of rock into space, plenty splashed back onto its sides like tremendous tidal waves. It widened Dimorphos, transforming it from a squat orb into a flat-topped oval -- like an M&M candy. That the asteroid acted like a fluid comes down to its peculiar composition. It's not a solid contiguous rock, but more like "a pile of sand," said Sabina Raducan, a planetary scientist at the University of Bern in Switzerland and the study's lead author. And a low-density asteroid barely held together by its own gravity was never going to respond in a straightforward manner when a van-size spacecraft flew into its face.

Dimorphos's response is "completely outside of the realm of physics as we understand it" in our day-to-day lives, said Cristina Thomas, the lead of the mission's observations working group at Northern Arizona University who was not involved with the study. And "this has overarching implications for planetary defense." DART showed that a tiny spacecraft can deflect an asteroid. But the study indicates that crashing a similarly disjointed space rock too forcefully risks fragmenting it, which, in a real asteroid emergency, could create multiple Earthbound asteroids. Planetary defense, as a concept, clearly works. "We know we can do it," said Federica Spoto, an asteroid dynamics researcher at the Center for Astrophysics, Harvard and Smithsonian, who was not involved with the new study. "But we have to do it right."

The Guardian reports: The Covid death toll in the U.S. is likely at least 16% higher than the official tally, according to a new study, and researchers believe the cause of the undercounting goes beyond overloaded health systems to a lack of awareness of Covid and low levels of testing.

The second year of the pandemic also had nearly as many uncounted excess deaths as the first, the study found.

More than 1.1 million Americans have died from Covid, according to official records. But the actual number is assuredly higher, given the high rates of excess deaths. Demographers wanted to know how many could be attributed to Covid, and they drilled down to data at the county level to discover patterns in geography and time. There were 1.2 million excess deaths from natural causes — excluding deaths from accidents, firearms, suicide and overdoses — between March 2020 and August 2022, the researchers estimated, and about 163,000 of those deaths were not attributed to Covid in any way — but most of them should have been, the researchers say... "The mortality that's not considered Covid starts a little bit before the Covid surges officially start and crests a little bit sooner," said Elizabeth Wrigley-Field, associate professor in the department of sociology and the Minnesota Population Center at the University of Minnesota and one of the study's authors. That indicates some people didn't realize their illness was Covid, due to a lack of awareness about its prevalence and low levels of testing. There was also a rise in out-of-hospital deaths — in homes and nursing homes, for instance — which makes ascertaining the cause of death more difficult...

"[W]e find over the first 30 months of the pandemic that serious gaps remained in surveillance," said Andrew Stokes, associate professor of global health and sociology at Boston University and one of the study's authors. "Even though we got a lot better at testing for Covid, we were still missing a lot of official Covid deaths" in the U.S., said Jennifer Dowd, professor of demography and population health at University of Oxford, who was not involved in this research. The phenomenon "underscores how badly the U.S. fared as the pandemic continued," Wrigley-Field said. "It does profoundly reflect failures in the public health system."
One of the study's authors told the Guardian that the hardest-hit areas were non-metropolitan counties, especially in the west and the south, with fewer resources for investigating deaths (and lower testing levels) — as well as different methodologies for assembling the official numbers.

An anonymous reader quotes a report from The Guardian: Air pollution from traffic is linked to some of the more severe forms of dementia, and could be a significant cause of the condition among those who are not already genetically predisposed to it, research suggests. Research carried out in Atlanta, Georgia, found that people with higher exposure to traffic-related fine particulate matter air pollution were more likely to have high amounts of the amyloid plaques in their brains that are associated with Alzheimer's. The findings, which will alarm anyone living in a town or city, but particularly those living near busy roads, add to the harms already known to be caused by road traffic pollution, ranging from climate change to respiratory diseases.

A team of researchers from Atlanta's Emory University set out to specifically investigate the effects on people's brains of exposure the type of fine particulate matter known as PM2.5. This consists of particles of less than 2.5 microns in diameter -- about a hundredth the thickness of a human hair -- suspended in the air, and is known to penetrate deep into living tissue, including crossing the blood-brain barrier. Traffic-related PM2.5 concentrations are a major source of ambient pollution in the metro-Atlanta area, and also in urban centers across the planet. [...] "We found that donors who lived in areas with high concentrations of traffic-related air pollution exposure, in particular PM2.5 exposure, had higher levels of Alzheimer's disease neuropathology in their brain," said Anke Huels, an assistant professor at Emory University in Atlanta, who was the lead author on the study. "In particular, we looked at a score that is used to evaluate evaluate amyloid plaques in the brain, in autopsy samples, and we showed that donors who live in areas with higher levels of air pollution, and also higher levels of amyloid plaques in their brain."

There was a positive relationship between exposure to high levels of PM2.5 and levels of amyloid plaques in the brains of the subjects the team examined. They found that people with a 1 ug/m3 higher PM2.5 exposure in the year before death were nearly twice as likely to have higher levels of amyloid plaques in their brains, while those with higher exposure in the three years before death were 87% more likely to have higher levels of plaques. Huels and her team also investigated whether having the main gene variant associated with Alzheimer's disease, ApoE4, had any effect on the relationship between air pollution and signs of Alzheimer's in the brain. "We found that the association between In air pollution and severity of Alzheimer's disease was stronger among those who did not carry an ApoE4 allele, those who did not have that strong genetic risk for Alzheimer disease," Huels said. "Which kind of suggests that environmental exposures like air pollution may explain some of the Alzheimer's risk in people whose risk cannot be explained by genetic risk factor." The findings have been published in the online issue of Neurology, the medical journal of the American Academy of Neurology.

Following a recent ruling from the state supreme court, the University of Alabama at Birmingham health system said it is pausing all in vitro fertilization (IVF) treatments for fear of criminal prosecution or punitive damages. On Friday, the Alabama Supreme Court ruled that frozen embryos are "children," entitled to full personhood rights, and anyone who destroys them could be liable in a wrongful death case. The Hill reports: "We are saddened that this will impact our patients' attempt to have a baby through IVF, but we must evaluate the potential that our patients and our physicians could be prosecuted criminally or face punitive damages for following the standard of care for IVF treatments," the health system said. [...] It is standard practice in IVF to fertilize several eggs and then transfer one into a woman's uterus. Any remaining normally developing embryos can be, at the patient's request and consent, frozen for later use. But legal experts say it's unclear if the standard practice is illegal in Alabama and could make IVF virtually inaccessible in the state.

According to the American Society of Reproductive Medicine, the best-developing embryo will be transferred into a patient for an attempt at a pregnancy while the rest are frozen for later use, in case the first one does not develop into a live birth, or the patient later desires another child. According to the Centers for Disease Control and Prevention, approximately 238,126 patients underwent IVF treatment in 2021, resulting in the births of 97,128 babies, the last year for which statistics were available. There are 453 IVF clinics nationwide.

Academics have found that the U.S. mortality declines during recessions, with "reductions in air pollution... a quantitatively important mechanism." Abstract of a paper on National Bureau of Economic Research: We leverage spatial variation in the severity of the Great Recession across the United States to examine its impact on mortality and to explore implications for the welfare consequences of recessions. We estimate that an increase in the unemployment rate of the magnitude of the Great Recession reduces the average, annual age-adjusted mortality rate by 2.3 percent, with effects persisting for at least 10 years. Mortality reductions appear across causes of death and are concentrated in the half of the population with a high school degree or less. We estimate similar percentage reductions in mortality at all ages, with declines in elderly mortality thus responsible for about three-quarters of the total mortality reduction. Recession-induced mortality declines are driven primarily by external effects of reduced aggregate economic activity on mortality, and recession-induced reductions in air pollution appear to be a quantitatively important mechanism. Incorporating our estimates of pro-cyclical mortality into a standard macroeconomics framework substantially reduces the welfare costs of recessions, particularly for people with less education, and at older ages where they may even be welfare-improving.

Jennifer Ouellette reports via Ars Technica: Famed naturalist Charles Darwin amassed an impressive personal library over the course of his life, much of which was preserved and cataloged upon his death in 1882. But many other items were lost, including more ephemeral items like unbound volumes, pamphlets, journals, clippings, and so forth, often only vaguely referenced in Darwin's own records. For the last 18 years, the Darwin Online project has painstakingly scoured all manner of archival records to reassemble a complete catalog of Darwin's personal library virtually. The project released its complete 300-page online catalog -- consisting of 7,400 titles across 13,000 volumes, with links to electronic copies of the works -- to mark Darwin's 215th birthday on February 12.

"This unprecedentedly detailed view of Darwin's complete library allows one to appreciate more than ever that he was not an isolated figure working alone but an expert of his time building on the sophisticated science and studies and other knowledge of thousands of people," project leader John van Wyhe of the National University of Singapore said. "Indeed, the size and range of works in the library makes manifest the extraordinary extent of Darwin's research into the work of others."

An anonymous reader quotes a report from Ars Technica: The Alabama Supreme Court on Friday ruled that frozen embryos are "children," entitled to full personhood rights, and anyone who destroys them could be liable in a wrongful death case. The first-of-its-kind ruling throws into question the future use of assisted reproductive technology (ART) involving in vitro fertilization for patients in Alabama -- and beyond. For this technology, people who want children but face challenges to conceiving can create embryos in clinical settings, which may or may not go on to be implanted in a uterus.

In the Alabama case, a hospital patient wandered through an unlocked door, removed frozen, preserved embryos from subzero storage and, suffering an ice burn, dropped the embryos, killing them. Affected IVF patients filed wrongful-death lawsuits against the IVF clinic under the state's Wrongful Death of a Minor Act. The case was initially dismissed in a lower court, which ruled the embryos did not meet the definition of a child. But the Alabama Supreme Court ruled that "it applies to all children, born and unborn, without limitation." In a concurring opinion, Chief Justice Tom Parker cited his religious beliefs and quoted the Bible to support the stance.

"Human life cannot be wrongfully destroyed without incurring the wrath of a holy God, who views the destruction of His image as an affront to Himself," Parker wrote. "Even before birth, all human beings bear the image of God, and their lives cannot be destroyed without effacing his glory." In 2020, the US Department of Health and Human Services estimated that there were over 600,000 embryos frozen in storage around the country, a significant percentage of which will likely never result in a live birth. The result of this ruling "could mean that any embryos that are destroyed or discarded in the process of IVF or afterward could be the subject of wrongful death lawsuits," notes Ars. [According to national ART data collected by the Centers for Disease Control and Prevention, the percentage of egg retrievals that fail to result in a live birth ranges from 46 percent to 91 percent, depending on the patient's age. Meanwhile, the percentage of fertilized egg or embryo transfers that fail to result in a live birth range from 51 percent to 76 percent, depending on age.]

"The ruling creates potentially paralyzing liability for ART clinics and patients who use them. Doctors may choose to only attempt creating embryos one at a time to avoid liability attached to creating extras, or they may decline to provide IVF altogether to avoid liability when embryos do not survive the process. This could exacerbate the already financially draining and emotionally exhausting process of IVF, potentially putting it entirely out of reach for those who want to use the technology and putting clinics out of business."

Medical alarms don't have to be louder to be more effective. Scientific American: Beeping alarms in hospitals are a life-or-death matter -- but with so many going off all the time, medical professionals may experience alarm fatigue that impairs care. Researchers now report that changing an alarm's sound to incorporate properties of musical instruments can make it more helpful amid the din. Auditory alarms can sound up to 300 times a day per patient in U.S. hospitals, but only a small fraction require immediate action.

Data from the U.S. Food and Drug Administration suggest that alarm fatigue (including when clinicians turned off or forgot to restart alarms) and other alarm-related issues were linked to 566 deaths over five and a half years. After a typical day at the hospital, "I'd leave with beeping in my ears," says Vanderbilt University Medical Center anesthesiologist Joseph Schlesinger. He collaborated with Michael Schutz, a music cognition researcher at McMaster University in Ontario, to analyze how musical sounds could improve hospital alarms.

In 2015 Schutz and Schlesinger began examining musical qualities called timbres that might let softer sounds command attention from busy clinicians. They found that sounds with a "percussive" timbre, many of which contain short bursts of high-frequency energy -- such as wineglasses clinking -- stand out even at low volume. In contrast, loud, "flat" tones that lack high-frequency components, like a reversing truck's beep, get lost. The researchers have since conducted experiments in which participants evaluate different sounds and melodies for annoyance, detectability and recognizability. For a recent study detailed in Perioperative Care and Operating Room Management, the researchers played participants the same sequences of notes with varying timbres. They found the sounds that made these sequences least annoying, with no decrease in recall, were percussive and had complex, time-varied harmonic overtones (the many components within a single sound) like a xylophone's ping, rather than a few homogeneous ones like monotonous mechanical beeps.

An anonymous reader quotes a report from Wired: Death is coming for the old-school gas furnace -- and its killer is the humble heat pump. They're already outselling gas furnaces in the US, and now a coalition of states has signed an agreement to supercharge the gas-to-electric transition by making it as cheap and easy as possible for their residents to switch. Nine states have signed a memorandum of understanding that says that heat pumps should make up at least 65 percent of residential heating, air conditioning, and water-heating shipments by 2030. ("Shipments" here means systems manufactured, a proxy for how many are actually sold.) By 2040, these states -- California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island -- are aiming for 90 percent of those shipments to be heat pumps.

"It's a really strong signal from states that they're committed to accelerating this transition to zero-emissions residential buildings," says Emily Levin, senior policy adviser at the Northeast States for Coordinated Air Use Management (NESCAUM), an association of air-quality agencies, which facilitated the agreement. The states will collaborate, for instance, in pursuing federal funding, developing standards for the rollout of heat pumps, and laying out an overarching plan "with priority actions to support widespread electrification of residential buildings."

Instead of burning planet-warming natural gas, a heat pump warms a building by transferring heat from the outdoor air into the interior space. Run it in the opposite direction, and it can cool the inside of a building -- a heat pump is both a heater and AC unit. Because the system is electric, it can run off a grid increasingly powered by renewables like wind and solar. Even if you have to run a heat pump with electricity from fossil-fuel power plants, it's much more efficient than a furnace, because it's moving heat instead of creating it. A heat pump can save an average American household over $550 a year, according to one estimate. They've gotten so efficient that even when it's freezing out, they can still extract warmth from the air to heat a home. You can even install a heat pump system that also warms your water. "These states are aiming to further collaborate with those heat pump manufacturers by tracking sales and overall progress, sending a signal to the industry to ramp up production to meet the ensuing demand," reports Wired. "They'll also collaborate with each other on research and generally share information, working toward the best strategies for realizing the transition from gas to electric."

"Basically, they're pursuing a sort of standardization of the policies and regulations for getting more heat pumps built, bought, and installed, which other states outside of the coalition might eventually tap into."

Clay Risen reports via the New York Times: David Kahn, whose 1967 book, "The Codebreakers," established him as the world's pre-eminent authority on cryptology -- the science of making and breaking secret codes -- died on Jan. 24 in the Bronx. He was 93. His son Michael said the death, at a senior-living facility, was from the long-term effects of a stroke in 2015.

Before Mr. Kahn's book, cryptology itself was something of a secret. Despite an explosion in cryptological technology and techniques during the 20th century and the central role they played during World War II, the subject was typically overlooked by historians, if only because their possible sources were still highly classified. "Codebreaking is the most important form of secret intelligence in the world today," Mr. Kahn wrote in his book's preface. "Yet it has never had a chronicler."

Over the course of more than 1,000 pages, along with some 150 pages of notes, Mr. Kahn laid out cryptology's long history, starting with ancient Egypt 4,000 years ago and proceeding through the French and American revolutions, the innovations wrought by the advent of the telegraph and telephone to the mid-20th century and the dawn of computer-assisted code breaking.

John Walker, the founder of computer-aided design software company Autodesk and co-author of AutoCAD, passed away on February 2nd. He was 74. Consultant and programmer Owen Wengerd shared the news on behalf of John's family (via Scanalyst, a website created by John): It is with great sadness that we announce John's death on Friday, February 2, 2024. He was born in Maryland, USA to William and Bertha Walker, who preceded him in death. John is survived by his wife Roxie Walker and a brother, Bill Walker of West Virginia. Declining to follow in his family tradition of becoming a medical doctor, John attended Case Western Reserve University (CWRU) to pursue a future in astronomy. However, after he discovered the brave new world of computers, he never looked back. John worked at the university's Project Chi (X) computing center where he studied computer science and earned a degree in electrical engineering.

John met Roxie on Thanksgiving Day in 1972, and they married the following year. Roxie and John drove cross-country a few months later for John's new job in California. Eventually he left that first job and worked at various others in the bay area. In late 1976, John designed his own circuit board based on the then-new Texas Instruments TMS9900 microprocessor. This venture became Marinchip Systems, and eventually led to Autodesk. The beginnings of Autodesk are well documented by John himself in The Autodesk File 2.0k and from there John's story is best told by John himself in his prodigious work, which is all methodically organized and available to the public at his website Fourmilab 1.4k.

An anonymous reader shares an essay: No one clicks a webpage hoping to learn which cat can haz cheeseburger. Weirdos, maybe. Sickos. No, we get our content from a For You Page now -- algorithmically selected videos and images made by our favorite creators, produced explicitly for our preferred platform. Which platform doesn't matter much. So long as it's one of the big five. Creators churn out content for all of them. It's a technical marvel, that internet. Something so mindblowingly impressive that if you showed it to someone even thirty years ago, their face would melt the fuck off. So why does it feel like something's missing? Why are we all so collectively unhappy with the state of the web?

A tweet went viral this Thanksgiving when a Twitter user posed a question to their followers. (The tweet said: "It feels like there are no websites anymore. There used to be so many websites you could go on. Where did all the websites go?") A peek at the comments, and I could only assume the tweet struck a nerve. Everyone had their own answer. Some comments blamed the app-ification of the web. "Everything is an app now!," one user replied. Others point to the death of Adobe Flash and how so many sites and games died along with it. Everyone agrees that websites have indeed vanished, and we all miss the days we were free to visit them.

Cancer deaths in the United States are falling, with four million deaths prevented since 1991, according to the American Cancer Society's annual report. At the same time, the society reported that the number of new cancer cases had ticked up to more than two million in 2023, from 1.9 million in 2022. The New York Times: Cancer remains the second leading cause of death in the United States, after heart disease. Doctors believe that it is urgent to understand changes in the death rate, as well as changes in cancer diagnoses. The cancer society highlighted three chief factors in reduced cancer deaths: declines in smoking, early detection and greatly improved treatments. Breast cancer mortality is one area where treatment had a significant impact. In the 1980s and 1990s, metastatic breast cancer "was regarded as a death sentence," said Donald Berry, a statistician at the University of Texas MD Anderson Cancer Center and an author of a new paper on breast cancer with Sylvia K. Plevritis of Stanford University and other researchers (several authors of the paper reported receiving payments from companies involved in cancer therapies).

The paper, published Tuesday in JAMA, found that the death rate from breast cancer had fallen to 27 per 100,000 women in 2019 from 48 per 100,000 in 1975. That includes metastatic cancer, which counted for nearly 30 percent of the reduction in the breast cancer death rate. Breast cancer treatment has improved so much that it has become a bigger factor than screening in saving lives, said Ruth Etzioni, a biostatistician at the Fred Hutchinson Cancer Center. Death rates have even declined among women in their 40s, who generally did not have regular mammograms, said Dr. Mette Kalager, a professor of medicine at the University of Oslo and Oslo University Hospital, "indicating a substantial effect of treatment," she said.

Michaela Zee reports via Variety: More than 15 years after his death, stand-up comedian George Carlin has been brought back to life in an artificial intelligence-generated special called "George Carlin: I'm Glad I'm Dead." The hour-long special, which dropped on Tuesday, comes from Dudesy, a comedy AI that hosts a podcast and YouTube show with "Mad TV" alum Will Sasso and podcaster Chad Kultgen.

"I just want to let you know very clearly that what you're about to hear is not George Carlin. It's my impersonation of George Carlin that I developed in the exact same way a human impressionist would," Dudesy said at the beginning of the special. "I listened to all of George Carlin's material and did my best to imitate his voice, cadence and attitude as well as the subject matter I think would have interested him today. So think of it like Andy Kaufman impersonating Elvis or like Will Ferrell impersonating George W. Bush."

In the stand-up special, the AI-generated impression of Carlin, who died in 2008 of heart failure, tackled prevalent topics like mass shootings, the American class system, streaming services, social media and AI itself. "There's one line of work that is most threatened by AI -- one job that is most likely to be completely erased because of artificial intelligence: stand-up comedy," AI-generated Carlin said. "I know what all the stand-up comics across the globe are saying right now: "I'm an artist and my art form is too creative, too nuanced, too subtle to be replicated by a machine. No computer program can tell a fart joke as good as me.'" Kelly Carlin, the late stand-up comedian's daughter, posted a statement in response to the special: "My dad spent a lifetime perfecting his craft from his very human life, brain and imagination. No machine will ever replace his genius. These AI generated products are clever attempts at trying to recreate a mind that will never exist again. Let's let the artist's work speak for itself. Humans are so afraid of the void that we can't let what has fallen into it stay there.

Here's an idea, how about we give some actual living human comedians a listen to? But if you want to listen to the genuine George Carlin, he has 14 specials that you can find anywhere."

The BBC checks in on "the pioneers of space exploration — the 24 Nasa astronauts who travelled to the Moon in the Apollo missions of the 1960s and 1970s." Ken Mattingly and Frank Borman died within a few days of each other late last year. Now only eight people who have voyaged beyond the Earth's orbit remain. Who are they, and what are their stories...? There are only four people still alive who have walked on the Moon — Charlie Duke is one of them. He did it aged 36, making him the youngest person to set foot on the lunar surface... Charlie Duke now lives outside San Antonio, Texas, with Dorothy, to whom he has been married for 60 years....

Jim Lovell is one of only three men to have travelled to the Moon twice, and following Frank Borman's death in November 2023, he became the oldest living astronaut....

After leaving Nasa in 1975, [Harrison Schmitt] was elected to the U.S. Senate from his home state of New Mexico, but only served one term. Since then he has worked as a consultant in various industries as well as continuing in academia.
And when confronted by a man claiming Apollo 11 was an elaborate lie, 72-year-old Buzz Aldrin "punched him on the jaw." Despite struggles in later life, he never lost his thirst for adventure and joined expeditions to both the North and South Poles, the latter at the age of 86. While embracing his celebrity, he has remained an advocate for the space programme, especially the need to explore Mars.

"I don't think we should just go there and come back — we did that with Apollo," he says.
Last 93-year-old Buzz Aldrin got married — and thanked his fans for remembering his birthday. "It means a lot and I hope to continue serving a greater cause for many more revolutions around the sun."

A cartel in the embattled central Mexico state of Michoacan set up its own makeshift internet antennas and told locals they had to pay to use its wifi service or they would be killed, according to prosecutors. New submitter awwshit shares a story: Dubbed "narco-antennas" by local media, the cartel's system involved internet antennas set up in various towns built with stolen equipment. The group charged approximately 5,000 people elevated prices between 400 and 500 pesos ($25 and $30) a month, the Michoacan state prosecutor's office told the Associated Press. That meant the group could rake in about $150,000 a month. People were terrorized "to contract the internet services at excessive costs, under the claim that they would be killed if they did not," prosecutors said, though they did not report any such deaths. Local media identified the criminal group as a faction known as Los Viagras. Prosecutors declined to say which cartel was involved because the case was still under investigation, but they confirmed Los Viagras dominates the towns forced to make the wifi payments.

fahrbot-bot shares a report from The Guardian: Scientists have discovered an entirely new class of antibiotic that appears to kill one of three bacteria considered to pose the greatest threat to human health because of their extensive drug-resistance. Zosurabalpin defeated highly drug-resistant strains of Carbapenem-resistant Acinetobacter baumannii (Crab) in mouse models of pneumonia and sepsis, and was being tested in human trials. Crab is classified as a priority 1 critical pathogen by the World Health Organization, alongside two other drug-resistant forms of bacteria -- Pseudomonas aeruginosa and Enterobacteriaceae.

Antibiotic-resistant infections pose an urgent threat to human health -- particularly those caused by a large group of bacteria known as Gram-negative bacteria, which are protected by an outer shell containing a substance called lipopolysaccharide (LPS). "LPS allows bacteria to live in harsh environments, and it also allows them to evade attack by our immune system," said Dr Michael Lobritz, the global head of infectious diseases at Roche Pharma Research and Early Development in Basel Switzerland, which developed the new drug. No new antibiotic for Gram-negative bacteria have been approved in more than 50 years.

Roche had previously identified Zosurabalpin as capable of blocking the growth of A baumannii but it was not clear how it worked, or if it would be effective in animals with Crab-related infections. Through a series of experiments published in Nature, Prof Daniel Kahne at Harvard University in Cambridge, US, and colleagues showed that the drug prevented LPS from being transported to the outer membrane of the bacterium, killing it. They also found that Zosurabalpin considerably reduced levels of bacteria in mice with Crab-induced pneumonia and prevented the death of those with Crab-related sepsis. While [Lobritz] stressed that this molecule alone would not solve the public health threat of antimicrobial resistant infections, the discovery could lay the foundations for future efforts to drug the same transport system in other bacteria.

This summer 80 million Americans were experiencing 105-degree heat. And tonight the Washington Post identifies what was unique about 2023's weather: "the heat's all-consuming relentlessness.

"It went day by day, continent by continent, until people all over the map, whether in the Amazon or the Pacific islands or rural Greece, had glimpsed a climate future for which they are not prepared..." Even if its extremes are ultimately eclipsed, as seems inevitable, 2023 will mark a point when humanity crossed into a new climate era — an age of "global boiling," as United Nations Secretary General António Guterres called it. The year included the hottest single day on record (July 6) and the hottest ever month (July), not to mention the hottest June, the hottest August, the hottest September, the hottest October, the hottest November, and probably the hottest December. It included a day, November 17, when global temperatures, for the first time ever, reached 2 degrees Celsius above the preindustrial levels.

Discomfort, destruction, and death are the legacy of those records.

In Phoenix, a heat wave went on for so long, with 31 consecutive days above 110 Fahrenheit, that one NASA atmospheric scientist called it "mind-boggling." The surrounding county recorded a record number of heat deaths, nearly 600. In Brazil, drought sapped the normally lush Amazon, causing towns to ration drinking water, contributing to the deaths of endangered pink dolphins, and choking off the river-based system of travel and commerce... At one point the coastal Florida Keys waters reached 100 degrees, comparable to a hot tub...

One explanation for 2023's extreme heat is El Niño — a recurring oceanic phenomenon that warms the waters in the Pacific and causes a global ripple of consequences. But the scale of this year's heat — amplified by human-caused factors and the burning of fossil fuels — is still well beyond what most scientists had thought possible. Some have theorized that planetary warming may be accelerating. Others have said there's not enough evidence. What they agree upon, though, is that the earth is trending toward more extreme heat. That means that the experiences of 2023 can seem astonishing in the short-term but will one day look tame.

This year, then, will wind up as the first — and almost surely not the last — in which temperatures were at or near 1.5 Celsius above preindustrial levels, a threshold the Paris agreement has aimed to avoid.
The article includes two more sobering statistics:

• "The University of Maine's Climate Change Institute logs daily global temperatures going back to 1940. From this July on, almost without fail, every daily temperature in 2023 topped the daily temperature from the same date in any of the prior 83 years."

• "In Brazil, the Rio Negro, one of the Amazon's main tributaries, fell to its lowest level since record keeping began more than a century earlier."

An anonymous reader quotes a report from New Atlas: Researchers have developed a new, lightweight foam made from carbon nanotubes that, when used as a helmet liner, absorbed the kinetic energy caused by an impact almost 30 times better than liners currently used in US military helmets. The foam could prevent or significantly reduce the likelihood of concussion in military personnel and sportspeople. Among sportspeople and military vets, traumatic brain injury (TBI) is one of the major causes of permanent disability and death. Injury statistics show that the majority of TBIs, of which concussion is a subtype, are associated with oblique impacts, which subject the brain to a combination of linear and rotational kinetic energy forces and cause shearing of the delicate brain tissue.

To improve their effectiveness, helmets worn by military personnel and sportspeople must employ a liner material that limits both. This is where researchers from the University of Wisconsin-Madison come in. Determined to prevent -- or lessen the effect of -- TBIs caused by knocks to the body and head, they've developed a new lightweight foam material for use as a helmet liner. For the current study, Thevamaran built upon his previous research into vertically aligned carbon nanotube (VACNT) foams -- carefully arranged layers of carbon cylinders one atom thick -- and their exceptional shock-absorbing capabilities. Current helmets attempt to reduce rotational motion by allowing a sliding motion between the wearer's head and the helmet during impact. However, the researchers say this movement doesn't dissipate energy in shear and can jam when severely compressed following a blow. Instead, their novel foam doesn't rely on sliding layers.

VACNT foam sidesteps this shortcoming via its unique deformation mechanism. Under compression, the VACNTs undergo collective sequentially progressive buckling, from increased compliance at low shear strain levels to a stiffening response at high strain levels. The formed compression buckles unfold completely, enabling the VACNT foam to accommodate large shear strains before returning to a near initial state when the load is removed. The researchers found that at 25% precompression, the foam exhibited almost 30 times higher energy dissipation in shear -- up to 50% shear strain -- than polyurethane-based elastomeric foams of similar density. The study has been published in the journal Experimental Mechanics.
