Why the pandemic probably started in the Wuhan research lab, in five key points

Why the pandemic probably started in the Wuhan research lab, in five key points

Alina Chan writes: On Monday, Dr. Anthony Fauci will return to the halls of Congress to testify before the House subcommittee investigating the Covid-19 pandemic. He will most likely be questioned about how the National Institute of Allergy and Infectious Diseases, which he directed until retiring in 2022, supported risky virus work at a Chinese institute whose research may have caused the pandemic. For more than four years, reflexive partisan politics have derailed the search for the truth about a…

2023 set record for U.S. heat deaths, killing in areas that used to handle the heat

The Associated Press reports: David Hom suffered from diabetes and felt nauseated before he went out to hang his laundry in 108-degree weather, another day in Arizona’s record-smashing, unrelenting July heat wave. His family found the 73-year-old lying on the ground, his lower body burned. Hom died at the hospital, his core body temperature at 107 degrees. The death certificates of more than 2,300 people who died in the United States last summer mention the effects of excessive heat, the…

Hundreds of Palestinian doctors disappeared into Israeli detention

Hundreds of Palestinian doctors disappeared into Israeli detention

The Intercept reports: It’s been two months since Osaid Alser has heard from his cousin, Khaled Al Serr, a surgeon at Nasser Hospital in the southern Gaza Strip city of Khan Younis. Before late March, they had been in regular contact — or as regular as the shredded communication infrastructure would allow. Al Serr had created a telemedicine WhatsApp group where he and Osaid, a surgical resident in the U.S., recruited doctors from stateside, the U.K., and Europe to give…

Animals self-medicate with plants − behavior people have observed and emulated for millennia

Animals self-medicate with plants − behavior people have observed and emulated for millennia

A goat with an arrow wound nibbles the medicinal herb dittany. O. Dapper, CC BY By Adrienne Mayor, Stanford University When a wild orangutan in Sumatra recently suffered a facial wound, apparently after fighting with another male, he did something that caught the attention of the scientists observing him. The animal chewed the leaves of a liana vine – a plant not normally eaten by apes. Over several days, the orangutan carefully applied the juice to its wound, then covered…

How 3M executives convinced a scientist the forever chemicals she found in human blood were safe

How 3M executives convinced a scientist the forever chemicals she found in human blood were safe

ProPublica reports: Kris Hansen had worked as a chemist at the 3M Corporation for about a year when her boss, an affable senior scientist named Jim Johnson, gave her a strange assignment. 3M had invented Scotch Tape and Post-­it notes; it sold everything from sandpaper to kitchen sponges. But on this day, in 1997, Johnson wanted Hansen to test human blood for chemical contamination. Several of 3M’s most successful products contained man-made compounds called fluorochemicals. In a spray called Scotchgard,…

Medical workers evacuated from Gaza, but three Americans refuse to leave

The Intercept reports: Some 20 American and British medical workers who had been unable to leave Gaza were evacuated from the European Hospital in Khan Younis on Friday, though three American members of medical missions refused to evacuate until Israel allows additional humanitarian workers to replace them. They remain at work, along with doctors and staff from separate medical missions, serving a population trapped in Gaza with no escape. The missions, as is often the case, had been scheduled to…

‘More Neanderthal than human’: How your health may depend on DNA from our long-lost ancestors

‘More Neanderthal than human’: How your health may depend on DNA from our long-lost ancestors

Live Science reports: The group had traveled for thousands of miles, crossing Africa and the Middle East until finally reaching the dimly lit forests of the new continent. They were long-vanished members of our modern human tribe, and among the first Homo sapiens to enter Europe. There, these people would likely have encountered their distant cousins: Neanderthals. These small bands of modern-human relatives had hooded brows, large heads and squat bodies, and they had spent epochs acclimating to Europe’s colder…

Increase in infectious diseases strongly associated with loss of biodiversity

Increase in infectious diseases strongly associated with loss of biodiversity

Anthropocene reports: When the COVID-19 pandemic struck the world in 2020, it drew attention to the ways environmental damage can set the stage for disease outbreaks. Scientists pointed to the potential roles of urbanization, habitat loss, and trade in live animals for helping to fuel a disease that many scientists think leapt from wild animals to people. While all those factors might have influenced this particular pandemic, they aren’t the main ways that environmental destruction threatens to amplify infectious disease….

Gaza’s unexploded-bomb crisis

Gaza’s unexploded-bomb crisis

Isaac Chotiner writes: Late last month, Charles (Mungo) Birch, who oversees the United Nations Mine Action Service (UNMAS) in the Palestinian territories, issued a warning about the dangers posed by unexploded ordnance in Gaza, especially if and when Gazan civilians return to the enclave’s north. (On Tuesday, the Israeli military entered the southern city of Rafah, after ordering tens of thousands of people to evacuate, and took control of the Rafah border crossing.) Birch said that more unexploded missiles and…

Tyson Foods dumps millions of pounds of toxic pollutants into rivers and lakes

The Guardian reports: Tyson Foods dumped millions of pounds of toxic pollutants directly into American rivers and lakes over the last five years, threatening critical ecosystems, endangering wildlife and human health, a new investigation reveals.

Pregnant women are being turned away from emergency rooms with fatal consequences

The Associated Press reports: One woman miscarried in the restroom lobby of a Texas emergency room as front desk staff refused to admit her. Another woman learned that her fetus had no heartbeat at a Florida hospital, the day after a security guard turned her away from the facility. And in North Carolina, a woman gave birth in a car after an emergency room couldn’t offer an ultrasound. The baby later died. Complaints that pregnant women were turned away from…

A toxic grass that threatens a quarter of U.S. cows is spreading. Can it be stopped?

A toxic grass that threatens a quarter of U.S. cows is spreading. Can it be stopped?

Robert Langellier writes: America’s “fescue belt,” named for an exotic grass called tall fescue, dominates the pastureland from Missouri and Arkansas in the west to the coast of the Carolinas in the east. Within that swath, a quarter of the nation’s cows — more than 15 million in all — graze fields that stay green through the winter while the rest of the region’s grasses turn brown and go dormant. But the fescue these cows are eating is toxic. The…

Yes, social media really is a cause of the epidemic of teenage mental illness

Jon Haidt writes: For centuries, adults have worried about whatever “kids these days” are doing. From novels in the 18th century to the bicycle in the 19th and through comic books, rock and roll, marijuana, and violent video games in the 20th century, there are always those who ring alarms, and there are always those who are skeptics of those alarms. So far, the skeptics have been right more often than not, and when they are right, they earn the…

Common plastic additive, BPA, linked to autism and ADHD, scientists find

Science Alert reports: The number of people being diagnosed with autism spectrum disorder ( ASD) and attention deficit hyperactivity disorder ( ADHD) has risen sharply in recent decades, and research continues to delve into the factors involved in these conditions. A study revealed there’s a difference in how children with autism or ADHD clear the common plastic additive bisphenol A (BPA), compared to neurotypical children. BPA is used in a lot of plastics and plastic production processes, and can also…

Urban humans have lost much of their ability to digest plants

Urban humans have lost much of their ability to digest plants

John Timmer writes: Cellulose is the primary component of the cell walls of plants, making it the most common polymer on Earth. It’s responsible for the properties of materials like wood and cotton and is the primary component of dietary fiber, so it’s hard to overstate its importance to humanity. Given its ubiquity and the fact that it’s composed of a bunch of sugar molecules linked together, its toughness makes it very difficult to use as a food source. The…
