AI chatbots show dementia-like cognitive decline in tests, raising questions about their future in medicine

AI chatbots show dementia-like cognitive decline in tests, raising questions about their future in medicine

The British Medical Journal reports: Almost all leading large language models or “chatbots” show signs of mild cognitive impairment in tests widely used to spot early signs of dementia, finds a study in the Christmas issue of the BMJ. The results also show that “older” versions of chatbots, like older patients, tend to perform worse on the tests. The authors say these findings “challenge the assumption that artificial intelligence will soon replace human doctors.” Huge advances in the field of…

Giant companies took secret payments to allow free flow of opioids

Giant companies took secret payments to allow free flow of opioids

The New York Times reports: In 2017, the drug industry middleman Express Scripts announced that it was taking decisive steps to curb abuse of the prescription painkillers that had fueled America’s overdose crisis. The company said it was “putting the brakes on the opioid epidemic” by making it harder to get potentially dangerous amounts of the drugs. The announcement, which came after pressure from federal health regulators, was followed by similar declarations from the other two companies that control access…

Amazon disregarded internal warnings on injuries, Senate investigation claims

Amazon disregarded internal warnings on injuries, Senate investigation claims

The New York Times reports: For years, worker advocates and some government officials have argued that Amazon’s strict production quotas lead to high rates of injury for its warehouse employees. And for years, Amazon has rejected the criticism, arguing that it doesn’t use strict quotas, and that its injury rates are falling close to or below the industry average. On Sunday, the majority staff of the Senate Committee on Health, Education, Labor and Pensions, which is chaired by Senator Bernie…

McConnell defends polio vaccine, an apparent warning to RFK Jr.

The New York Times reports: Senator Mitch McConnell, the former Republican leader and a survivor of polio, issued a pointed statement in support of the polio vaccine on Friday, hours after The New York Times reported that the lawyer for Robert F. Kennedy Jr. has petitioned federal regulators to withdraw the vaccine from the market. Without naming Mr. Kennedy, Mr. McConnell suggested that the petition could jeopardize his confirmation to be health secretary in the incoming Trump administration. “Efforts to…

‘Unprecedented risk’ to life on Earth: Scientists call for halt on ‘mirror life’ microbe research

‘Unprecedented risk’ to life on Earth: Scientists call for halt on ‘mirror life’ microbe research

The Guardian reports: World-leading scientists have called for a halt on research to create “mirror life” microbes amid concerns that the synthetic organisms would present an “unprecedented risk” to life on Earth. The international group of Nobel laureates and other experts warn that mirror bacteria, constructed from mirror images of molecules found in nature, could become established in the environment and slip past the immune defences of natural organisms, putting humans, animals and plants at risk of lethal infections. Although…

A new theory of placebos reframes the mind-body problem

A new theory of placebos reframes the mind-body problem

Dien Ho writes: When healthcare researchers test potential new treatments, they use randomized clinical trials. Since the 1950s, placebos have been crucial parts of these trials. The placebo is made to resemble the treatment being tested, but lacks the experimental ingredients. For the treatment to be deemed efficacious, it must outperform the placebo, which is given to a control group. Otherwise, the treatment’s positive effects may be “mere” placebo effects. Advocates of evidence-based medicine consider double-blind randomized clinical trials with…

A CEO’s killing echoes the political violence of the Gilded Age

A CEO’s killing echoes the political violence of the Gilded Age

Zeynep Tufekci writes: I’ve been studying social media for a long time, and I can’t think of any other incident when a murder [that of UnitedHealthcare CEO Brian Thompson] in this country has been so openly celebrated. The conditions that gave rise to this outpouring of anger are in some ways specific to this moment. Today’s business culture enshrines the maximization of executive wealth and shareholder fortunes, and has succeeded in leveraging personal riches into untold political influence. New communication…

Sick animals suggest COVID pandemic started in Wuhan market

Sick animals suggest COVID pandemic started in Wuhan market

Nature reports: The quest to understand where the COVID-19 pandemic started has revealed fresh clues. Researchers have re-analysed data collected from a market in Wuhan, China, during the early days of the pandemic and found that animals there were infected with a virus – although they could not confirm what exactly caused the infection. “The conclusion is convincing that there was infection in the animals,” says Spyros Lytras, an evolutionary virologist at the University of Tokyo. The results, which have…

Will Joe Biden’s legacy not only be another Trump term but also another pandemic?

Will Joe Biden’s legacy not only be another Trump term but also another pandemic?

Zeynep Tufekci writes: Almost five years after Covid blew into our lives, the main thing standing between us and the next global pandemic is luck. And with the advent of flu season, that luck may well be running out. The H5N1 avian flu, having mutated its way across species, is raging out of control among the nation’s cattle, infecting roughly a third of the dairy herds in California alone. Farmworkers have so far avoided tragedy, as the virus has not…

Trump blocks RFK Jr’s hoped for influence over the agricultural industry

Trump blocks RFK Jr’s hoped for influence over the agricultural industry

Politico reports: Robert F. Kennedy Jr. spent weeks lobbying Donald Trump to nominate an Agriculture secretary who would be his ally in a war with the sugar, soybean, corn and other farm commodity interests he argues are poisoning Americans. Working largely from his home in California, Trump’s pick to lead the Department of Health and Human Services even meticulously vetted and put forward his own list of candidates to run the massive agency responsible for the country’s farm and food…

Big pharma is the only reason anyone still dies from HIV

Big pharma is the only reason anyone still dies from HIV

Charlotte Kilpatrick writes: The year is 1998. While antiviral drugs to treat HIV had been approved a decade earlier, only five out of 33 million people who carried the virus were receiving the life-saving treatment. Nowhere was the situation worse than in South Africa. The country had the highest global prevalence of the disease with nearly one in five people infected and 200,000 children orphaned. Treatment options were limited. That year, the Minister of Health released a report outlining the…

As climate change melts permafrost, microbes that we have never been exposed to will emerge

As climate change melts permafrost, microbes that we have never been exposed to will emerge

Valerie Brown writes: The popular image of the Arctic is as a “frozen North,” which it was for all of human history until a couple of centuries ago. In that view, intrepid explorers and scientists clatter over tundra and ice roads in dogsleds and decrepit trucks, risking everything to bring back important samples and wild tales of howling winds. But this vision is growing passé. The Arctic is warming four times as fast as the global average. While there are…

The growing enthusiasm among tech elites for genetically engineering their children

Emily R. Klancher Merchant writes: In the Operation Varsity Blues scandal of 2019, 50 wealthy parents were charged with trying to get their children into elite universities through fraudulent means. The story dramatically demonstrated the lengths to which some parents will go to ensure their children’s acceptance into places like Stanford, Yale, Georgetown, and USC. Actress Lori Loughlin and her husband, fashion designer Mossimo Giannulli, bribed athletic coaches to recruit their children for sports they did not play. Actress Felicity Huffman…

Why walking helps us think

Why walking helps us think

Ferris Jabr writes: In Vogue’s 1969 Christmas issue, Vladimir Nabokov offered some advice for teaching James Joyce’s “Ulysses”: “Instead of perpetuating the pretentious nonsense of Homeric, chromatic, and visceral chapter headings, instructors should prepare maps of Dublin with Bloom’s and Stephen’s intertwining itineraries clearly traced.” He drew a charming one himself. Several decades later, a Boston College English professor named Joseph Nugent and his colleagues put together an annotated Google map that shadows Stephen Dedalus and Leopold Bloom step by…

How Elon Musk muzzled government employees from talking about xAI’s new supercomputer

Forbes reports: Nearly six months ago in Memphis, before residents or even city councilors knew that Elon Musk was building “the world’s largest supercomputer” in their backyard, the billionaire’s team met secretly with a host of local and national law enforcement agencies including the sheriff’s office, Memphis Police Department, U.S. Department of Homeland Security and Federal Bureau of Investigations. The covert meeting, which has not been previously reported, concerned Musk’s growing AI startup xAI, according to the Greater Memphis Chamber,…

Trump picks RFK Jr. to oversee the Department of Health and Human Services

NPR reports: President-elect Donald Trump has tapped Robert F. Kennedy Jr. — a former independent presidential candidate who has a history of spreading conspiracy theories, including about vaccines — to oversee the Department of Health and Human Services. “For too long, Americans have been crushed by the industrial food complex and drug companies who have engaged in deception, misinformation, and disinformation when it comes to Public Health,” Trump said in a statement on Truth Social. “The Safety and Health of…
