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

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

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…

The terrible costs of a phone-based childhood

The terrible costs of a phone-based childhood

Jonathan Haidt writes: Something went suddenly and horribly wrong for adolescents in the early 2010s. By now you’ve likely seen the statistics: Rates of depression and anxiety in the United States—fairly stable in the 2000s—rose by more than 50 percent in many studies from 2010 to 2019. The suicide rate rose 48 percent for adolescents ages 10 to 19. For girls ages 10 to 14, it rose 131 percent. The problem was not limited to the U.S.: Similar patterns emerged around the same…

Salty foods are making people sick − in part by poisoning their microbiomes

Salty foods are making people sick − in part by poisoning their microbiomes

Salt has taken over many diets worldwide – some more than others. ATU Images/The Image Bank via Getty Images By Christopher Damman, University of Washington People have been using salt since the dawn of civilization to process, preserve and enhance foods. In ancient Rome, salt was so central to commerce that soldiers were paid their “salarium,” or salaries, in salt, for instance. Salt’s value was in part as a food preservative, keeping unwanted microbes at bay while allowing desired ones…

Landmark study links microplastics to serious health problems

Landmark study links microplastics to serious health problems

Nature reports: Plastics are just about everywhere — food packaging, tyres, clothes, water pipes. And they shed microscopic particles that end up in the environment and can be ingested or inhaled by people. Now the first data of their kind show a link between these microplastics and human health. A study of more than 200 people undergoing surgery found that nearly 60% had microplastics or even smaller nanoplastics in a main artery. Those who did were 4.5 times more likely…

The trauma experienced in Gaza is beyond PTSD

The trauma experienced in Gaza is beyond PTSD

Yara M. Asi writes: “We will die. All of us. Hopefully soon enough to stop the suffering that we are living through every single second.” Those words were sent in a text last week by a physician working for Doctors Without Borders in the southern Gaza Strip. And it is far from an uncommon feeling shared by those struggling to survive and care for one another in Gaza these days. What would we call this feeling from the perspective of…

Alabama justice who ruled embryos are people says American law should be rooted in the Bible

Alabama justice who ruled embryos are people says American law should be rooted in the Bible

NBC News reports: On the same day that Alabama Supreme Court Chief Justice Tom Parker handed down an opinion declaring that fertilized frozen embryos are people, imperiling women’s access to in vitro fertilization treatments, he espoused support for a once-fringe philosophy that calls on evangelical Christians to reshape society based on their interpretation of the Bible. During an online broadcast hosted by Tennessee evangelist Johnny Enlow on Friday, Parker suggested America was founded explicitly as a Christian nation and discussed…

Plastics reckoning: PVC is ubiquitous, but maybe not for long

Plastics reckoning: PVC is ubiquitous, but maybe not for long

Nicola Jones writes: The word “vinyl” might sound innocuous, bringing to mind everyday items like LP records, flooring, pipes, or shiny plastic pants. The plastic this name refers to — polyvinyl chloride (PVC) — is the world’s third-most widely produced synthetic polymer, with more than 50 million tons cranked out each year for everything from window frames to food wrap, fake leather car seats to medical products. It’s everywhere. But environmentalists and NGOs have been raising alarms about PVC for…

A pediatrician’s two weeks inside a hospital in Gaza

Isaac Chotiner interviewed Dr. Seema Jilani, a senior technical adviser at the International Rescue Committee who went to Al-Aqsa Hospital in central Gaza to aid the humanitarian effort there in December: We worked alongside the Palestinian physicians and nurses there, and we really think it’s important to work alongside them and learn from them. We were in one of the last enduring emergency rooms in central Gaza. Within the two weeks that I was there, I saw it go from…

How Big Pharma is fueling a radical MAGA agenda

How Big Pharma is fueling a radical MAGA agenda

Rolling Stone reports: Big Pharma has invested big money in the organizations planning what a MAGA policy agenda will look like in a new Trump administration. Not surprisingly, that policy playbook contains a major gift for the drug industry: a swift end to the Biden administration’s landmark program to allow Medicare to negotiate lower drug prices. For two decades, Congress barred Medicare from negotiating prescription drug prices, which is a major reason why Americans pay higher prices for drugs than…

U.S. states had an estimated 65,000 rape-related pregnancies after banning abortion

U.S. states had an estimated 65,000 rape-related pregnancies after banning abortion

NPR reports: As an abortion provider in Montana, Dr. Samuel Dickman has seen patients routinely who tell him they became pregnant after a rape. His sense was the patients who were telling him were only a fraction of the true number. “There are certainly far more survivors of rape who become pregnant as a result, who — for totally understandable reasons — don’t want to disclose that fact to a medical provider that they just met.” Dickman used to live…

Gaza’s indirect casualties mount as health service decimated

Gaza’s indirect casualties mount as health service decimated

The Guardian reports: Health services in Gaza are “decimated”, with medical staff exhausted after three months of war forced to extract shrapnel without adequate pain relief, conduct amputations without anaesthetics and watch children die of cancers because of a lack of facilities and medicine. Dozens of interviews with doctors and medical administrators in Gaza reveal a catastrophic and deteriorating situation as health services struggle to cope with tens of thousands of casualties of the continuing Israeli offensive in the territory…

Humans are increasingly passing pathogens to animal populations

Humans are increasingly passing pathogens to animal populations

Nature reports: There was something wrong with the chimpanzees. For weeks, a community of 205 animals in Uganda’s Kibale National Park had been coughing, sneezing and looking generally miserable. But no one could say for sure what ailed them, even as the animals began to die. Necropsies can help to identify a cause of death, but normally, the bodies of chimps that succumb to disease are found long after decomposition has set in, if at all. So when Tony Goldberg,…

‘Deep concern’ for patients and staff at Gaza’s al-Aqsa hospital

‘Deep concern’ for patients and staff at Gaza’s al-Aqsa hospital

BBC News reports: The three doctors from the UK [Deborah Harrington, Nick Maynard, and James Smith] said they witnessed “horrific” injuries and challenging conditions inside al-Aqsa hospital. “We had no running water in theatres, so we had no ability to scrub up and wash,” Mr Maynard said of the surgical unit. “We just had to use alcohol gel before operating.” “There were no drapes to cover the patients in theatres, so we had to use makeshift gowns to try to…
