Alex Orlando writes: Well, damn. Maybe you stubbed your toe first thing in the morning. Or some thoughtless commuter forced you to slam the brakes on the drive to work. Perhaps you’re just fed up with it all and feel like sinking to your knees and cursing the heavens. If you’ve ever suppressed the urge to unleash a string of obscenities, maybe think again. Some research suggests that it might be a better idea to simply let the filth fly….
Katherine J. Wu writes: For three years now, the debate over the origins of the coronavirus pandemic has ping-ponged between two big ideas: that SARS-CoV-2 spilled into human populations directly from a wild-animal source, and that the pathogen leaked from a lab. Through a swirl of data obfuscation by Chinese authorities and politicalization within the United States, and rampant speculation from all corners of the world, many scientists have stood by the notion that this outbreak—like most others—had purely natural…
Yasemin Saplakoglu writes: Our bodies consist of about 30 trillion human cells, but they also host about 39 trillion microbial cells. These teeming communities of bacteria, viruses, protozoa and fungi in our guts, in our mouths, on our skin and elsewhere — collectively called the human microbiome — don’t only consist of freeloaders and lurking pathogens. Instead, as scientists increasingly appreciate, these microbes form ecosystems essential to our health. A growing body of research aims to understand how disruptions of…
The Washington Post reports: The first course was a celery root soup lush with whole milk. The last was a spice cake topped with maple cream cheese frosting served with a side of ice cream. And then a latte with its fat cap of glossy foam. In all, a delicious lunch. Maybe a little heavy on the dairy. Only this dairy was different. It was not the product of a cow or soybean or nut. The main ingredient of this…
BBC News reports: More than half the world’s population will be classed as obese or overweight by 2035 if action is not taken, the World Obesity Federation warns. More than four billion people will be affected, with rates rising fastest among children, its report says. Low or middle-income countries in Africa and Asia are expected to see the greatest rises. The report predicts the cost of obesity will amount to more than $4tn (£3.3tn) annually by 2035. The president of…
The Washington Post reports: The theory that covid-19 started with a lab accident in central China received a modest boost in the latest U.S. intelligence assessment after the work of a little-known scientific team that conducts some of the federal government’s most secretive and technically challenging investigations of emerging security threats, current and former U.S. officials said Monday. An analysis by experts from the U.S. national laboratory complex — including members of a storied team known as Z-Division — prompted…
BBC Future reports: On 6 June, satellite images captured hundreds of craters made by artillery shells and a 40m-wide (131 ft) hole left by a bomb in fields around the village of Dovhenke, in eastern Ukraine. It is just one site left scarred by Russia’s invasion of its neighbour. And as the war continues to wreak a devastating humanitarian toll on the people caught up in the fighting, the conflict is leaving a far less obvious, toxic legacy on the land itself….
The Wall Street Journal reports: The U.S. Energy Department has concluded that the Covid pandemic most likely arose from a laboratory leak, according to a classified intelligence report recently provided to the White House and key members of Congress. The shift by the Energy Department, which previously was undecided on how the virus emerged, is noted in an update to a 2021 document by Director of National Intelligence Avril Haines’s office. The new report highlights how different parts of the…
Emily Harwitz writes: When Masashi Soga was growing up in Japan, he loved spending time outside catching insects and collecting plants. His parents weren’t big fans of the outdoors, but he had an elementary schoolteacher who was. “They taught me how to collect butterflies, how to make a specimen of butterflies,” Soga recalls. “I enjoyed nature quite a lot.” That early exposure helped foster Soga’s appreciation for nature, he says, and today, Soga is an ecologist at the University of…
The New York Times reports: Deaths in state and federal prisons across America rose nearly 50 percent during the first year of the pandemic, and in six states they more than doubled, according to the first comprehensive data on prison fatalities in the era of Covid-19. The tremendous jump in deaths in 2020 was more than twice the increase in the United States overall, and even exceeded estimates of the percentage increase at nursing homes, among the hardest-hit sectors nationwide….
NBC News reports: Immunity acquired from a Covid infection provides strong, lasting protection against the most severe outcomes of the illness, according to research published Thursday in The Lancet — protection, experts say, that’s on par with what’s provided through two doses of an mRNA vaccine. Infection-acquired immunity cut the risk of hospitalization and death from a Covid reinfection by 88% for at least 10 months, the study found. “This is really good news, in the sense that protection against…

Nature reports: Three years into the pandemic, the immune systems of the vast majority of humans have learnt to recognize SARS-CoV-2 through vaccination, infection or, in many cases, both. But just how quickly do these types of immunity fade? New evidence suggests that ‘hybrid’ immunity, the result of both vaccination and a bout of COVID-19, can provide partial protection against reinfection for at least eight months1. It also offers greater than 95% protection against severe disease or hospitalization for between…
The New York Times reports: In 2016, a blockbuster drug called Humira was poised to become a lot less valuable. The key patent on the best-selling anti-inflammatory medication, used to treat conditions like arthritis, was expiring at the end of the year. Regulators had blessed a rival version of the drug, and more copycats were close behind. The onset of competition seemed likely to push down the medication’s $50,000-a-year list price. Instead, the opposite happened. Through its savvy but legal…
Nature reports: The emergence of disease-causing bacteria that are resistant to antibiotics is often attributed to the overuse of antibiotics in people and livestock. But researchers have homed in on another potential driver of resistance: antidepressants. By studying bacteria grown in the laboratory, a team has now tracked how antidepressants can trigger drug resistance1. “Even after a few days exposure, bacteria develop drug resistance, not only against one but multiple antibiotics,” says senior author Jianhua Guo, who works at the…
Nature reports: Most studies on how humans acquire their microbiomes have focused on people’s first contact with microbes: through their mums. “It’s key to providing a microbial starter kit,” says Hilary Browne, a microbiologist at the Wellcome Sanger Institute in Hinxton, UK. To examine how and why this starter kit changes over a person’s life, a team led by microbiome researchers Mireia Valles-Colomer and Nicola Segata at the University of Trento, Italy, analysed DNA from nearly 10,000 stool and saliva…
