An anonymous reader quotes a report from Wired: A little over three years have passed since McDonald's sent out an email to thousands of its restaurant owners around the world that abruptly cut short the future ofa three-person startup called Kytch -- and with it, perhaps one of McDonald's best chances for fixing its famously out-of-order ice cream machines. Until then, Kytch had been selling McDonald's restaurant owners a popular internet-connected gadget designed to attach to their notoriously fragile and often broken soft-serve McFlurry dispensers, manufactured by McDonalds equipment partner Taylor. The Kytch device would essentially hack into the ice cream machine's internals, monitor its operations, and send diagnostic data over the internet to an owner or manager to help keep it running. But despite Kytch's efforts to solve the Golden Arches' intractable ice cream problems, a McDonald's email in November 2020 warned its franchisees not to use Kytch, stating that it represented a safety hazard for staff. Kytch says its sales dried up practically overnight.

Now, after years of litigation, the ice-cream-hacking entrepreneurs have unearthed evidence that they say shows that Taylor, the soft-serve machine maker, helped engineer McDonald's Kytch-killing email -- kneecapping the startup not because of any safety concern, but in a coordinated effort to undermine a potential competitor. And Taylor's alleged order, as Kytch now describes it, came all the way from the top. On Wednesday, Kytch filed a newly unredacted motion for summary adjudication in its lawsuit against Taylor for alleged trade libel, tortious interference, and other claims. The new motion, which replaces a redacted version from August, refers to internal emails Taylor released in the discovery phase of the lawsuit, which were quietly unsealed over the summer. The motion focuses in particular on one email from Timothy FitzGerald, the CEO of Taylor parent company Middleby, that appears to suggest that either Middleby or McDonald's send a communication to McDonald's franchise owners to dissuade them from using Kytch's device.

"Not sure if there is anything we can do to slow up the franchise community on the other solution," FitzGerald wrote on October 17, 2020. "Not sure what communication from either McD or Midd can or will go out." In their legal filing, the Kytch cofounders, of course, interpret "the other solution" to mean their product. In fact, FitzGerald's message was sent in an email thread that included Middleby's then COO, David Brewer, who had wondered earlier whether Middleby could instead acquire Kytch. Another Middleby executive responded to FitzGerald on October 17 to write that Taylor and McDonald's had already met the previous day to discuss sending out a message to franchisees about McDonald's lack of support for Kytch. But Jeremy O'Sullivan, a Kytch cofounder, claims -- and Kytch argues in its legal motion -- that FitzGerald's email nonetheless proves Taylor's intent to hamstring a potential rival. "It's the smoking gun," O'Sullivan says of the email. "He's plotting our demise."

schwit1 shares a report from the New York Post: A landmark study out of the University of Adelaide and University of Essex has found that living in a private rental property accelerates the biological aging process by more than two weeks every year. The research found renting had worse effects on biological age than being unemployed (adding 1.4 weeks per year), obesity (adding 1 week per year), or being a former smoker (adding about 1.1 weeks). University of Adelaide Professor of Housing Research Emma Baker said private renting added "about two-and-a-half weeks of aging" per year to a person's biological clock, compared to those who own their homes.

"In fact, private rental is the really interesting thing here, because social renters, for some reason, don't seem to have that effect," Professor Baker told the ABC News Daily podcast. She said the security of social renting -- aka public housing -- and homeownership has compared to people living with an end-of-lease date on their calendars. "When you look at big studies of the Australian population, you see that the average rental lease is between six and 12 months," she said. "So even if you have your lease extended, you still are living in that slight state of kind of unknowingness, really not quite secure if your lease is actually going to be extended or not." "We think that that is one of the things that's contributing to loss of years, effectively."

A study of more than 2 million people's internet use found no "smoking gun" for widespread harm to mental health from online activities such as browsing social media and gaming, despite widely claimed concerns that mobile apps can cause depression and anxiety. From a report: Researchers at the Oxford Internet Institute, who said their study was the largest of its kind, said they found no evidence to support "popular ideas that certain groups are more at risk" from the technology. However, Andrew Przybylski, professor at the institute -- part of the University of Oxford -- said that the data necessary to establish a causal connection was "absent" without more co-operation from tech companies. If apps do harm mental health, only the companies that build them have the user data that could prove it, he said.

"The best data we have available suggests that there is not a global link between these factors," said Przybylski, who carried out the study with Matti Vuorre, a professor at Tilburg University. Because the "stakes are so high" if online activity really did lead to mental health problems, any regulation aimed at addressing it should be based on much more "conclusive" evidence, he added. "Global Well-Being and Mental Health in the Internet Age" was published in the journal Clinical Psychological Science on Tuesday. In their paper, Przybylski and Vuorre studied data on psychological wellbeing from 2.4 million people aged 15 to 89 in 168 countries between 2005 and 2022, which they contrasted with industry data about growth in internet subscriptions over that time, as well as tracking associations between mental health and internet adoption in 202 countries from 2000-19.

Doctors have long relied on a few key patient characteristics to assess risk of a heart attack or stroke, using a calculus that considers blood pressure, cholesterol, smoking and diabetes status, as well as demographics: age, sex and race. Now, the American Heart Association is taking race out of the equation. From a report: The overhaul of the widely used cardiac-risk algorithm is an acknowledgment that, unlike sex or age, race identification in and of itself is not a biological risk factor. The scientists who modified the algorithm decided from the start that race itself did not belong in clinical tools used to guide medical decision making, even though race might serve as a proxy for certain social circumstances, genetic predispositions or environmental exposures that raise the risk of cardiovascular disease.

The revision comes amid rising concern about health equity and racial bias within the U.S. health care system, and is part of a broader trend toward removing race from a variety of clinical algorithms. "We should not be using race to inform whether someone gets a treatment or doesn't get a treatment," said Dr. Sadiya Khan, a preventive cardiologist at Northwestern University Feinberg School of Medicine, who chaired the statement writing committee for the American Heart Association, or A.H.A. The statement was published on Friday [PDF] in the association's journal, Circulation. An online calculator using the new algorithm, called PREVENT, is still in development.

An anonymous reader quotes a report from NBC News: A prolonged decline in male fertility in the form of sperm concentrations appears to be connected to the use of pesticides, according to a study published Wednesday. Researchers compiled, rated and reviewed the results of 25 studies of certain pesticides and male fertility and found that men who had been exposed to certain classes of pesticides had significantly lower sperm concentrations. The study, published Wednesday in Environmental Health Perspectives, included data from more than 1,700 men and spanned several decades. "No matter how we looked at the analysis and results, we saw a persistent association between increasing levels of insecticide and decreases in sperm concentration," said study author Melissa Perry, who is an environmental epidemiologist and the dean of the College of Public Health at George Mason University. "I would hope this study would get the attention of regulators seeking to make decisions to keep the public safe from inadvertent, unplanned impacts of insecticides." [...]

Scientists have long suspected changes to the environment could be contributing, and they've been probing the role of pesticides for decades in studies of animals and in human epidemiology research. The new analysis focuses on two groups of chemicals -- organophosphates and some carbamates -- that are commonly used in insecticides. The researchers looked at data collected from groups of people with exposures to pesticides and others who were not. Most, but not all, of the research centered on exposures in the workplace. The researchers controlled for outside factors that could contribute to lower sperm counts like smoking and age. Perry said researchers aren't sure how pesticides are affecting sperm concentrations and more research will be needed.

It's likely that pesticides are one of many environmental factors that could be contributing to a decline in sperm concentrations. The trend of sperm concentration declines has been widely observed in studies around the world, but it's a complicated topic and some scientists still have reservations. Sperm are notoriously difficult to count and the technology to do so has changed over the years. There are many confounding factors that can affect male fertility, including age, obesity and opioid use, to name a few. Sperm concentrations are one important data point to consider, but other factors -- like how sperm are shaped and how they swim -- are also critical to male fertility. Perry said she hopes agencies like the Environmental Protection Agency begin to factor the impact of chemicals and pesticides on reproductive health in their assessments. "Given the body of evidence and these consistent findings, it's time to proactively reduce these insecticide exposures for men wanting to have families," Perry said.

A new study found that adult ADHD "may take a toll on the brain and is linked to a higher likelihood of developing dementia," reports the Washington Post: A study published in JAMA Network Open reported that being diagnosed with ADHD as an adult is associated with a 2.77-fold increased risk of dementia.

The study only showed an association and doesn't tell us whether ADHD is a direct cause of cognitive decline. But the results suggest that "if you do have attention-deficit disorder, you're going to have more trouble with normal brain aging," said Sandra Black, a cognitive neurologist at Sunnybrook Research Institute in Toronto who was not involved in the study. "It adds another risk factor...."

Notably, of the 730 participants with adult ADHD, 13.2 percent (96 participants) were diagnosed with dementia. In contrast, of the 108,388 participants without adult ADHD, just 7 percent (7,630 participants) developed dementia. Intriguingly, adults with ADHD who were taking a psychostimulant medication such as Ritalin or Adderall did not have an increased risk of developing dementia compared with those not taking medication. Only 22.3 percent of people with ADHD had taken a psychostimulant medication at any point.
The Post also notes the work of Sara Becker, a postdoctoral research associate at the University of Calgary. "In a 2023 systematic review, Becker and her colleagues identified only seven previous studies investigating the link between ADHD and neurodegenerative diseases such as dementia, most of which found that adult ADHD conferred a higher dementia risk."
The research highlights the importance of seeking care — and the need for more research. Treatment with psychostimulant medications may attenuate the risk, said Stephen Levine, a professor at the University of Haifa's School of Public Health in Israel and the lead author of the study. Lifestyle changes, such as better sleep and staying socially engaged, can also lower risk for dementia....

A 2020 landmark study by the Lancet Commission highlighted 12 modifiable factors for dementia that, if addressed, could mitigate the risk of dementia by up to 40 percent. Some of these factors are hearing loss, excessive alcohol intake and smoking.
Other lifestyle changes that lower your risk of demential include keeping up your physical activity, and eating a Mediterranean diet, the Post reports (citing cognitive neurologist Sandra Black).

An estimated 3 percent of adults have ADHD.

Long-time Slashdot reader RockDoctor writes: Regardless of their other potential benefits, modern cars, and modern electric cars in particular, involve complex networks of computer code, hardware, and servo systems cooperating (?) to deliver services to the user, like acceleration, steering and braking. Slashdot nerderati know better than most that such complex networks can never show unexpected, non-designed behavior, due to the infallibility of hardware, program coders and system designers... Yeah. Right. "I'll have some of what he's been smoking!" That's Musk-grade optimism.

On Sunday evening, a middle-aged driver in a "brand new" vehicle found it would not decelerate below 30mph (50kmph). He retained steering control, and avoided crashing until police vehicles "boxed in" his vehicle and helped him exit into a police van (most have sliding side doors) from the moving vehicle. The police then "carried out a controlled halt" on the unmanned vehicle, stopping it from driving away with the van's brakes until a roadside assistance technician arrived 3 hours later and managed to shut it down. "[W]hen the [technician] got to me [...] later, he plugged in the car to do a diagnostic check and there was pages of faults," said the "kidnapped" driver from Glasgow. "He said he had never seen anything like it and decided he was not willing to turn the engine on to see what was wrong."

By inference, the vehicle did not have a mechanical brake ("hand brake": English; "parking brake": American), which should have been able to keep the vehicle halted regardless of the motor's actions (even if a "clutch" did get burned out). From the only time I've been inside an electric car, I can't say if that is normal; it's certainly something I'll look for if I ever rent another. Had the failure happened at 10 a.m. in the morning, not 10 p.m. in the evening, the body count could have been ... substantial.

A dumb question, stemming from my only use of an electric car: do they have a weight sensor under the driver's seat that locks-out the main motor unless there is (say) 30kg in the driver's seat? Most have some such sensors -- they trigger the "seatbelt not fastened" alarm or silence it for empty seats -- but whether they can override the drive system ... ?

Cigarette smoking and other uses of tobacco shave an average of 2.2 years off lifespans globally. But merely breathing -- if the air is polluted -- is more damaging to human health. From a report: That is the conclusion of a report published Tuesday by the University of Chicago's Energy Policy Institute, which identified air pollution as the world's top threat to public health, responsible for reducing average life expectancy by 2.3 years worldwide. China, once the poster child for smog-filled skies, has been a surprise success story. Between 2013 and 2021, the world's second-largest economy improved overall air quality by more than 40% while the average lifespan of residents increased by more than two years, according to the report.

By contrast, four countries in South Asia -- India, Bangladesh Nepal and Pakistan -- accounted for more than half of the total years of life lost globally due to pollution in the atmosphere over the same eight years. India alone was responsible for nearly 60% of the growth in air pollution across the globe during that time. If India were to meet World Health Organization guidelines for particulate pollution, the life expectancy for residents of capital city New Delhi would increase by 12 years. An increase in wildfires in places such as California and Canada has renewed attention on the dangers of polluted air. Around 350 cities globally suffer the same level of dangerous haze that enveloped New York City in June at least once a year, according to calculations from environmental think tank Centre for Research on Energy and Clean Air, which aggregates data from dozens of official government sources.

An anonymous reader quotes a report from ProPublica: The Environmental Protection Agency approved a component of boat fuel made from discarded plastic that the agency's own risk formula determined was so hazardous, everyone exposed to the substance continually over a lifetime would be expected to develop cancer. Current and former EPA scientists said that threat level is unheard of. It is a million times higher than what the agency usually considers acceptable for new chemicals and six times worse than the risk of lung cancer from a lifetime of smoking. Federal law requires the EPA to conduct safety reviews before allowing new chemical products onto the market. If the agency finds that a substance causes unreasonable risk to health or the environment, the EPA is not allowed to approve it without first finding ways to reduce that risk. But the agency did not do that in this case. Instead, the EPA decided its scientists were overstating the risks and gave Chevron the go-ahead to make the new boat fuel ingredient at its refinery in Pascagoula, Mississippi. Though the substance can poison air and contaminate water, EPA officials mandated no remedies other than requiring workers to wear gloves, records show.

ProPublica and the Guardian in February reported on the risks of other new plastic-based Chevron fuels that were also approved under an EPA program that the agency had touted as a "climate-friendly" way to boost alternatives to petroleum-based fuels. That story was based on an EPA consent order, a legally binding document the agency issues to address risks to health or the environment. In the Chevron consent order, the highest noted risk came from a jet fuel that was expected to create air pollution so toxic that 1 out of 4 people exposed to it over a lifetime could get cancer. In February, ProPublica and the Guardian asked the EPA for its scientists' risk assessment, which underpinned the consent order. The agency declined to provide it, so ProPublica requested it under the Freedom of Information Act. The 203-page risk assessment revealed that, for the boat fuel ingredient, there was a far higher risk that was not in the consent order. EPA scientists included figures that made it possible for ProPublica to calculate the lifetime cancer risk from breathing air pollution that comes from a boat engine burning the fuel. That calculation, which was confirmed by the EPA, came out to 1.3 in 1, meaning every person exposed to it over the course of a full lifetime would be expected to get cancer.

Another serious cancer risk associated with the boat fuel ingredient that was documented in the risk assessment was also missing from the consent order. For every 100 people who ate fish raised in water contaminated with that same product over a lifetime, seven would be expected to develop cancer -- a risk that's 70,000 times what the agency usually considers acceptable. When asked why it didn't include those sky-high risks in the consent order, the EPA acknowledged having made a mistake. This information "was inadvertently not included in the consent order," an agency spokesperson said in an email. [...] The risk assessment makes it clear that cancer is not the only problem. Some of the new fuels pose additional risks to infants, the document said, but the EPA didn't quantify the effects or do anything to limit those harms, and the agency wouldn't answer questions about them. Some of these newly approved toxic chemicals are expected to persist in nature and accumulate in living things, the risk assessment said. That combination is supposed to trigger additional restrictions under EPA policy, including prohibitions on releasing the chemicals into water. Yet the agency lists the risk from eating fish contaminated with several of the compounds, suggesting they are expected to get into water. When asked about this, an EPA spokesperson wrote that the agency's testing protocols for persistence, bioaccumulation and toxicity are "unsuitable for complex mixtures" and contended that these substances are similar to existing petroleum-based fuels. The EPA did address the concerns in June when it proposed a rule that "would require companies to contact the agency before making any of 18 fuels and related compounds listed in the Chevron consent order," notes ProPublica. "The EPA would then have the option of requiring tests to ensure that the oil used to create the new fuels doesn't contain unsafe contaminants often found in plastic, including certain flame retardants, heavy metals, dioxins and PFAS. If approved, the rule will require Chevron to undergo such a review before producing the fuels, according to the EPA."

Thursday Bill Gates launched a new podcast called "Unconfuse Me." ("What do you do when you can't solve a problem? I like to talk to smart people who can help me understand the subject better...") Join me on my learning journey as I talk to brilliant guests about Alzheimer's, artificial intelligence, the future of education, plant-based meat, the evolution of language, marijuana, and more.
The first words of the first episode are a clip of Seth Rogen saying "Edibles? I don't mess with that. Snoop Dogg doesn't eat edibles. Like, that's how wild the variation on edibles is, and I do not recommend this."

Then Bill Gates' voice says "I love learning, even if a topic's complex, I like to see if I can figure it out..." People reports that the 67-year-old Microsoft co-founder and former CEO also spoke to Rogen and his wife Lauren Miller about the future of Alzheimer's research: With studies showing that "40% of cases" are preventable, according to Rogen, the "five brain healthy habits" in their framework are important: sleep, exercise, nutrition, mental fitness and emotional well-being.

He even confessed that his being a celebrity encourages people to better care for themselves. "I taught this coursework of brain health, and we've also had a neurologist teach the coursework, and we scientifically proved that people retain information better from celebrities than doctors, which is it's a heavy burden," he joked, adding that this information "was published..."

Miller also shared that she goes to a neurologist and the pair are both "open" with their doctors about their habits, and "no one" in the medical world has told them that smoking weed is bad for their brain health. They even believe its benefits of boosting hunger and relieving stress might be good for preventing Alzheimer's. "It's not federally legal, so there isn't money to fund research," Miller said.

Gates later concluded the podcast with his own funny anecdote, laughing about his first time he ever smoked weed — back when it was a "rebellious" thing to do. "In school out of the, say 105 people in my class I think, there were three or four who didn't smoke," he said. "Because it was kind of a, 'Hey, I'm an adult! Hey I can break the rules!' But I will say, sometimes it's like, I guess I'm doing this to be cool. It wasn't so much smoking for pot's sake."

CNN summarizes the issue. "A recent advisory from U.S. Surgeon General Dr. Vivek Murthy says there's not enough evidence to determine whether social media is safe enough for children and adolescents when it comes to their mental health." (Although a CNN news anchor points out that "Nearly all of the research points to negative impacts.")

CNN's Chief Medical Correspondent interviewed U.S. Surgeon General Dr. Vivek Murthy "to examine what led him to sound the alarm, and who should be responsible for tackling the issue." And the surgeon general remembers when his five-year-old daughter asked to post a picture on social media. "I think finding the right balance is not easy, in part because, you know, the platforms weren't necessarily designed for balance. They were designed to maximize how much time we spend on them." CNN: How worried are you? When people hear something coming from the surgeon general's office, they think of, you know, smoking, opioids, things like this. Social media — is it at that level of concern for you?

Surgeon General: Yes, I would say yes, it is. And, and — but it's it's more complicated... because we know that some kids do actually get benefit from their experience of social media. Some are able to connect more easily with friends and family, to express themselves more creatively and more openly than they otherwise would, and to find community... But one of the things that has become an increasing source of worry for me is that the the association between social media use and harmful outcomes... [W]e're asking parents to somehow figure it out all on their own. And the reason I issued an advisory on this topic is I worry that we have not taken enough action to support parents and kids...

CNN: What is the level of evidence about the dangers of social media and what is the level of evidence that you want? I mean, what does it take for you as a surgeon general to act on this...?

Surgeon General: I think the first question I'm asking is where is the evidence of safety...? There's a lot of association data, right, that's showing an association between use and certain and negative outcomes, like for example, for kids who who use more than 3 hours of social media a day, they face double the risk of depression and anxiety symptoms. But we also know that kids are telling us in their own words and their own experience how they're experiencing social media. So, for example, about nearly half of adolescents are saying that using social media makes them feel worse about their body image...

And one of the consistent messages I hear from researchers who's been studying this area for a long time is that they are having a hard time getting access to the data from social media companies. You know, as a parent, I don't ever want to feel like someone or anyone is hiding information from me about how a product affects my child. But that's how a lot of parents are feeling right now. And so that's a place where I think transparency matters. Let's get the data out there so independent researchers can assess it and can help us understand the harms and benefits and which kids are most impacted so we can design, you know, our approach, you know, in a more informed way...

One of the things we call for in my advisory is for the policymakers to step in and establish actual, transparent, enforceable safety standards like we do for other products so that parents have some reassurance around safety... This technology is already being used by 95% of kids, Right. And I don't think that's realistic to put the genie back in the bottle here or to say somehow nobody should be using social media, that that's not the goal here... We don't like leave it up to car manufacturers to determine whether or not they've hit the standards or not. We don't do that with medications either. There should be, you know, independent authority that parents can trust are looking primarily in solely out for the welfare of their kids, and they should be the ones who enforce these standards....

You know, just to put it bluntly, I do not think we have done our job as a society to have the backs of kids and parents on this because we haven't moved fast enough to get the information to ultimately guide them on safe use... [P]arents across the country, people are trying to do the best they can with limited information.
The surgeon general also says their ideal legislation would also "help to reduce kids exposure to harmful content" and include "restrictions on features that seek to manipulate kids into spending excessive amounts of time on these platforms."

An anonymous reader quotes a report from Ars Technica: After endless leaks, Motorola made its fourth-generation lineup of foldables official today. The flagship is the Moto Razr+, which will launch in the US on June 23 for $999. There's also a cheaper phone called only the "Moto Razr" with a smaller outside screen, slower SoC, and no clear US price or release date. Internationally, these phones are called the Moto Razr 40 Ultra and Moto Razr 40. The Ultra model's SoC is a Snapdragon 8+ Gen 1 -- that's not the best you can get from Qualcomm, which would be the 8 Gen 2 -- this is a year-old mid-cycle upgrade chip. The phone has 8GB of RAM, 256GB of storage, and a 3800 mAh battery with 30 W quick charging. The leaked display specs have been all over the place, but officially, the interior display is a 6.9-inch, 2640x1080 OLED that runs at a smoking 165 Hz. The exterior display is super big on the Ultra model and is a 3.6-inch, 144 Hz OLED at a nearly square 1066x1056. Motorola has the phone's dust and water ingress protection rated at IP52, which typically only protects from "direct sprays of water up to 15 degrees from the vertical" and is far from qualifying the Razr as a water-resistant phone.

The design has been better. The original foldable Moto Razr reboot from 2020 had beautiful throwback looks that screamed "Moto Razr." It looked just like the old-school flip phone from the early 2000s but modernized. This fourth foldable generation tones things down a lot and is more of a generic rectangle. You could easily confuse it for Samsung's Galaxy Z Flip. This fourth generation seems more mature, though. Motorola will now let you run any app you want on the ultra's giant front screen, complete with the option of a super tiny Android navigation bar tucked away in the bottom left corner, to the left of the two front cameras. You can peruse the app drawer, use Google Pay, or play media on the front display. You can even type on the keyboard: Google GBoard has a special full-screen mode that will show a single line of input text.

Those front cameras give this font display one of the strangest display shapes on the market. With two big dead spots in the bottom right corner, the workable display area is kind of an upside-down L shape. By default, apps will stay out of the non-rectangular part of the screen, but it's possible to enable a "full screen" mode for the front apps. This will force apps to use the lower part of the display, and you just have to hope that they will somehow deal with that. Android has APIs to identify dead areas of the display for apps to work around, but usually, that's for a top camera notch. Not many apps are built for this, but you're apparently welcome to try to make them work with the feature. [...] If you're interested in the Razr+, preorders start June 16.

As smoke began filling the cabin, an airplane passenger saw sparks and fire bursting from a bag in the seat directly behind her — which turned out to be a "smoky flashing lithium battery, which had begun smoldering in a carry-on bag," according to CBS News.

The flight crew contained the situation, and "Airport fire trucks met the plane on the runway and everyone evacuated safely." But a CBS News Investigation "has discovered similar incidents have been happening much more frequently in the skies over the United States." The FAA verifies the number of lithium-Ion battery fires jumped more 42% in the last five years. A CBS News analysis of the FAA's data found that since 2021 there's been at least one lithium battery incident on a passenger plane somewhere in the U.S., on average, once every week...

Some airlines are taking action to control the growing number of fires. They are using specialized "thermal containment" bags designed for flight crews to use if a lithium battery starts heating up to the point where it's smoking or burning. Mechanical engineers at the University of Texas at Austin say the bags can effectively contain fire and keep it from spreading, but don't extinguish it.
In a video accompanying the article, an engineering professor at the university's Fire Research Group even showed a lithium-ion battery fire that continued burning undewater. "You can't put it out. It's a fire within the cell. So, you've got fuel, oxygen, heat in the cell, all." (The article also notes a startup called Pure Lithium is working on a new kind of non-flammable battery using lithium metal cells instead of lithium ion).

Guidelines from America's Federal Aviation Administration require spare lithium-ion batteries be kept with passengers (and not checked) — and prohibits passengers from bringing onboard damaged or recalled batteries and battery-powered devices.

As the European Union gears up to enforce a major reboot of its digital rulebook in a matter of months, a new dedicated research unit is being spun up to support oversight of large platforms under the bloc's flagship Digital Services Act (DSA). From a report: The European Centre for Algorithmic Transparency (ECAT), which was officially inaugurated in Seville, Spain, today, is expected to play a major role in interrogating the algorithms of mainstream digital services -- such as Facebook, Instagram and TikTok.

ECAT is embedded within the EU's existing Joint Research Centre (JRC), a long-established science facility that conducts research in support of a broad range of EU policymaking, from climate change and crisis management to taxation and health sciences. But while the ECAT is embedded within the JRC -- and temporarily housed in the same austere-looking building (Seville's World Trade Centre), ahead of getting more open-plan bespoke digs in the coming years -- it has a dedicated focus on the DSA, supporting lawmakers to gather evidence to build cases so they can act on any platforms that don't take their obligations seriously. Commission officials describe the function of ECAT being to identify "smoking guns" to drive enforcement of the DSA -- say, for example, an AI-based recommender system that can be shown is serving discriminatory content despite the platform in question claiming to have taken steps to "de-bias" output -- with the unit's researchers being tasked with coming up with hard evidence to help the Commission build cases for breaches of the new digital rulebook.

An anonymous reader quotes a report from Mirage News: One million smokers will be encouraged to swap cigarettes for vapes under a pioneering new "swap to stop" scheme designed to improve the health of the nation and cut smoking rates. As part of the world-first national scheme, almost one in five of all smokers in England will be provided with a vape starter kit alongside behavioral support to help them quit the habit as part of a series of new measures to help the government meet its ambition of being smoke-free by 2030 -- reducing smoking rates to 5% or less. Local authorities will be invited to take part in the scheme later this year and will design a scheme which suits its needs, including deciding which populations to prioritize.

In a speech today, Health Minister Neil O'Brien will also announce that following the success of local schemes, pregnant women will be offered financial incentives to help them stop smoking. This will involve offering vouchers, alongside behavioral support, to all pregnant women who smoke by the end of next year. The government will also consult on introducing mandatory cigarette pack inserts with positive messages and information to help people to quit smoking. Additionally, there will be a crackdown on illicit vape sales as part of measures to stop children and non-smokers take up the habit -- which is growing in popularity among young people. Health Minister Neil O'Brien said in a statement: "Up to two out of three lifelong smokers will die from smoking. Cigarettes are the only product on sale which will kill you if used correctly. We will offer a million smokers new help to quit. We will be funding a new national 'swap to stop' scheme -- the first of its kind in the world. We will work with councils and others to offer a million smokers across England a free vaping starter kit."

"Drinking moderate amounts of alcohol every day does not — as once thought — protect against death from heart disease," writes the Washington Post, "nor does it contribute to a longer life, according to a sweeping new analysis of alcohol research." The review, which examined existing research on the health and drinking habits of nearly 5 million people, is one of the largest studies to debunk the widely held belief that moderate drinking of wine or other alcoholic beverages is good for you. Last year, researchers in Britain examined genetic and medical data of nearly 400,000 people and concluded that even low alcohol intake was associated with increased risk of disease.

The new study, which appears Friday in Jama Network Open, also found that drinking relatively low levels of alcohol — 25 grams a day for women (less than 1 ounce) and 45 grams (about 1.5 ounces) or more per day for men — actually increased the risk of death. A standard wine pour is about 5 ounces. The standard serving size for beer is 12 ounces, and for distilled spirits, 1.5 ounces. "This study punctures the hope of many that moderate alcohol use is healthy," said Robert DuPont, a psychiatrist and substance abuse expert who served as the first director of the National Institute on Drug Abuse.... Much of the research into the health effects of alcohol has been funded by the alcohol industry. One recent report found that 13,500 studies have been directly or indirectly paid for by the industry....

The new review, called a "meta-analysis," looked at 107 observational studies that involved more than 4.8 million people. The study stressed that previous estimates of the benefits of moderate alcohol consumption on the risk of death by "all causes" — meaning anything, including heart disease, cancer, infections and automobile accidents — were "significantly" biased by flaws in study design. Earlier research did not adjust for numerous factors that could influence the outcome, for example, age, sex, economic status and lifestyle behaviors such as exercise, smoking and diet, they said. Using statistical software, the researchers essentially removed the bias, adjusting for various factors that could skew the research. After doing so, they found no significant declines in the risk of death by any causes among the moderate drinkers.

Clancy William James writes via The Conversation: We have just published evidence in Nature Astronomy for what might be producing mysterious bursts of radio waves coming from distant galaxies, known as fast radio bursts or FRBs. Two colliding neutron stars -- each the super-dense core of an exploded star -- produced a burst of gravitational waves when they merged into a "supramassive" neutron star. We found that two and a half hours later they produced an FRB when the neutron star collapsed into a black hole. Or so we think. The key piece of evidence that would confirm or refute our theory -- an optical or gamma-ray flash coming from the direction of the fast radio burst -- vanished almost four years ago. In a few months, we might get another chance to find out if we are correct. [...]

The Laser Interferometer Gravitational-Wave Observatory (LIGO) has found two binary neutron star mergers. Crucially, the second, known as GW190425, occurred when a new FRB-hunting telescope called CHIME was also operational. However, being new, it took CHIME two years to release its first batch of data. When it did so, [Alexandra Moroianu, a masters student at the University of Western Australia and lead author of the study] quickly identified a fast radio burst called FRB 20190425A which occurred only two and a half hours after GW190425. Exciting as this was, there was a problem -- only one of LIGO's two detectors was working at the time, making it very uncertain where exactly GW190425 had come from. In fact, there was a 5% chance this could just be a coincidence. Worse, the Fermi satellite, which could have detected gamma rays from the merger -- the "smoking gun" confirming the origin of GW190425 -- was blocked by Earth at the time. [...]

LIGO and two other gravitational wave detectors, Virgo and KAGRA, will turn back on in May this year, and be more sensitive than ever, while CHIME and other radio telescopes are ready to immediately detect any FRBs from neutron star mergers. In a few months, we may find out if we've made a key breakthrough -- or if it was just a flash in the pan.

"With the recent attention on ChatGPT and OpenAI's release of their APIs, many developers have developed clients for modern platforms to talk to this super smart AI chatbot," writes maker/retro coding enthusiast yeokm1 . "However I'm pretty sure almost nobody has written one for a vintage platform like MS-DOS."

They share a blog post with all the details — including footage of their client ultimately running on a vintage IBM PC from 1984 (with a black and orange monitor and those big, boxy keys). "3.5 years ago, I wrote a Slack client to run on Windows 3.1," the blog post explains. "I thought to try something different this time and develop for an even older platform as a challenge."

One challenge was just finding a networking API for DOS. But everything came together, with the ChatGPT-for-DOS app written using Visual Studio Code text editor (testing on a virtual machine running DOS 6.22), parsing the JSON output from OpenAI's Chat Completion API. "And before you ask, I did not use ChatGPT for help to code this app in any way," the blog post concludes. But after the app was working, he used it to ask ChatGPT how one would build such an app — and ChatGPT erroneously suggested breezily that he just try accessing OpenAI's Python API from the DOS command line.

"What is the AI smoking...?"

"Astronomers spotted an unexpected trail in the gas surrounding a dwarf galaxy while using the Hubble Space Telescope...." writes Hot Hardware. "The light emitting from the trail traveled more than 7.5 billion years to reach Earth and is thought to be traveling at a breakneck speed of 1,600km/s (3.5 million mph).

Science Alert says it could be "the smoking gun pointing to a runaway supermassive black hole."

More from Universe Today: Supermassive black holes (SMBHs) lurk in the center of large galaxies like ours. From their commanding position in the galaxy's heart, they feed on gas, dust, stars, and anything else that strays too close, growing more massive as time passes. But in rare circumstances, an SMBH can be forced out of its position and hurtle through space as a rogue SMBH.

In a new paper, researchers from Canada, Australia, and the USA present evidence of a rogue SMBH that's tearing through space and interacting with the circumgalactic medium (CGM.) Along the way, the giant is creating shock waves and triggering star formation.... The paper hasn't been peer-reviewed yet....

In their paper, the authors explain how an SMBH can be cast out of its host galaxy. It always starts when galaxies merge. That leads to the formation of a binary SMBH at the center of the merger remnant. The binary SMBH can be very long-lived, surviving for as long as one billion years before merging. If during that time, a third SMBH reaches the galactic center, then a three-body interaction can give one of the SMBHs a velocity boost, and it can be driven from the galaxy.
Hot Hardware adds that "This is not the first time a supermassive black hole has been found ejected from the center of its host galaxy. However, this is the first time one has been detected speeding across intergalactic space and believed to be inactive."

And RockDoctor (Slashdot reader #15,477) explains that "After the collision and ejection from the galaxy core, the passage of the black hole through the galaxy and it's surrounding material produced a burst of star formation along that line, which we now see as a faint linear streak of light....

"Those who like doom-laden prophecies will be upset to hear that, because we can see this moving across the plane of the sky, it is never going to come any where near us."

An anonymous reader quotes a report from Ars Technica: According to a new study, a little over 70 percent of prescription drugs advertised on television were rated as having "low therapeutic value," meaning they offer little benefit compared with drugs already on the market. The study, appearing in JAMA Open Network, aligns with longstanding skepticism that heavily promoted drugs have high therapeutic value. "One explanation might be that drugs with substantial therapeutic value are likely to be recognized and prescribed without advertising, so manufacturers have greater incentive to promote drugs of lesser value," said the authors, which include researchers at Harvard, Yale, and Dartmouth.

For the new study, researchers led by Aaron Kesselheim, who leads Harvard's Program On Regulation, Therapeutics, And Law (PORTAL), looked at monthly lists of the top-advertised drugs on TV in the US between 2015 and 2021. They also looked up therapeutic value ratings for those drugs from independent health assessment agencies in Canada, France, and Germany. The value ratings were based on drugs' therapeutic benefit, safety profile, and strength of evidence, as compared with existing drugs. Any drug rated "moderate" or above was classified as a "high value" drug for the study. For drugs with multiple ratings, the study authors used the most favorable rating, which they note could overestimate the proportion of higher-benefit drugs.

Of the top advertised drugs, 73 had at least one value rating. Collectively, pharmaceutical companies spent $22.3 billion on advertising for those 73 drugs between 2015 and 2021. Even with the generous ratings, 53 of the 73 drugs (roughly 73 percent) were categorized as low-benefit. Collectively, these low-benefit drugs accounted for $15.9 billion of the ad spending. The top three low-benefit drugs by dollar amount were Dulaglutide (type 2 diabetes), Varenicline (smoking cessation), and Tofacitinib (rheumatoid arthritis). The outlook for change is bleak, the authors note. "Policy makers and regulators could consider limiting direct-to-consumer advertising to drugs with high therapeutic or public health value or requiring standardized disclosure of comparative effectiveness and safety data," Kesselheim and his colleagues concluded, "but policy changes would likely require industry cooperation or face constitutional challenge." The report notes that the U.S. is "one of only two countries that allows direct-to-consumer (DTC) drug advertisements, such as TV commercials." The other is New Zealand.
