Pesticides may wreak havoc on the gut microbiome

Pesticides may wreak havoc on the gut microbiome

Science reports: Eight years ago, Bhanudas More went for a routine blood test. More, a farmworker in this small village in Maharashtra state, was lean, worked long hours in the fields, and seemed healthy, so the result startled him. He was diagnosed with type 2 diabetes, a disease commonly associated with sedentary life in the city. Medication did little to bring his condition under control. He also began to experience persistent bloating and stomach discomfort. “I was taking the medicines,…

We are all collections of errors

Jerome Groopman writes: As I am writing this, my DNA is changing. And, as you read this, so is yours. People tend to assume that the genes we inherit from our parents are a fixed blueprint for our growth and development, immutable throughout our lives, and that the DNA in each cell of our body is the same as in every other cell. In fact, changes in our DNA, known as mutations, occur from the time we are in the…

What happens to your brain in nature? The neuroscience explained

Yoho National Park, Field, Canada. (Unsplash/Hendrik Cornelissen) By Mar Estarellas, McGill University Have you ever felt calmer almost as soon as you step into the woods? Or maybe noticed your busy mind soften as you look out at the sea? We have known for some time, and many of us sense it intuitively, that spending time in nature is good for us. Neuroscience is now enabling us to understand why, and what the brain is actually doing in those moments….

While fighting against regulation of social media, tech billionaires shield their own children

While fighting against regulation of social media, tech billionaires shield their own children

The New York Times reports: In November, Kim van Sparrentak, a Green Party lawmaker from the Netherlands, grabbed her headphones and headed for the exit of the European Parliament building. Moments earlier, she had participated in a heated debate over whether to bar young teenagers in Europe from social media platforms. Then a statement on a podcast she was listening to stopped her cold. It was a message from Meta opposing the social media ban proposal, Ms. van Sparrentak said…

RFK Jr. once led legal fight against Monsanto’s glyphosate. Now he supports Trump’s push to boost its production

RFK Jr. once led legal fight against Monsanto’s glyphosate. Now he supports Trump’s push to boost its production

The New York Times reports: President Trump issued an executive order late Wednesday aimed at spurring the domestic production of glyphosate, a widely used weedkiller that has figured in health lawsuits. The move immediately set off alarms among supporters of Health Secretary Robert F. Kennedy Jr.’s “Make America Healthy Again” movement, and appeared to put Mr. Kennedy in an awkward position. Glyphosate is the active ingredient in Roundup, which has been the target of tens of thousands of lawsuits that…

Venting anger does more harm than good

Venting anger does more harm than good

Science Alert reports: Venting when angry seems sensible. Conventional wisdom suggests that expressing anger can help us quell it, like releasing steam from a pressure cooker. But this common metaphor is misleading, according to a 2024 meta-analytic review. Researchers at Ohio State University analyzed 154 studies on anger and found little evidence that venting helps. In some cases, it could increase anger. “I think it’s really important to bust the myth that if you’re angry you should blow off steam…

In unprecedented move, giant monkey research center may become a primate sanctuary

In unprecedented move, giant monkey research center may become a primate sanctuary

The Physicians Committee for Responsible Medicine applauds the Oregon Health & Science University Board of Directors’ approval of a resolution authorizing negotiations with the National Institutes of Health to transition the Oregon National Primate Research Center (ONPRC) toward closure and potential conversion into a primate sanctuary. With passage of the resolution, OHSU is now positioned to work with the NIH to explore a pathway away from invasive primate experimentation and toward humane, human-relevant science. During a 180-day negotiation period authorized…

USAID’s demise heralded a dark shift in America’s values

USAID’s demise heralded a dark shift in America’s values

Jeremy Konyndyk writes: Last February, Elon Musk boasted of “feeding USAID into the woodchipper” as President Trump kicked off his second term with an unanticipated assault on the agency. A year later, the brutal fallout is coming into focus. Humanitarian aid last year reached 25 million fewer people than in 2024 despite rising global need. More than 2,000 health clinics have closed in crisis zones around the world. Global food aid funding dropped by 40 percent from 2024 to 2025….

Cells that are not our own may unlock secrets about our health

Cells that are not our own may unlock secrets about our health

Tracy DeStazio writes: During pregnancy, maternal and fetal cells migrate back and forth across the placenta, with fetal cells entering the mother’s bloodstream and tissues. They can settle in maternal organs such as the thyroid, liver, lungs, brain and heart—and can persist there for decades. Conversely, maternal cells can enter the fetus and be passed down to future generations, essentially creating a lifelong connection between mothers, their offspring and their descendants. In other words, we all carry little pieces of…

All living things emit a visible light that vanishes at death, surprising study says

All living things emit a visible light that vanishes at death, surprising study says

Science Alert reports: Life truly is radiant, according to an experiment conducted by researchers from the University of Calgary and the National Research Council of Canada. An extraordinary experiment on mice and leaves from two different plant species has uncovered direct physical evidence of an eerie ‘biophoton’ phenomenon ceasing on death, suggesting all living things – including humans – could literally glow with health, until we don’t. The findings might seem a little fringe at first glance. It’s hard not…

Trump will stop at nothing to ensure the political dominance of White people in America

Trump will stop at nothing to ensure the political dominance of White people in America

Regina Davis Moss writes: “We’ve dropped (the price of) the infertility drugs to make lots of Trump babies, I’m hoping by the midterms.” That bizarre remark was made recently by Dr. Mehmet Oz, administrator of the Centers for Medicare & Medicaid Services. After four years of the first Trump administration and nearly one year into the second, many of us have become desensitized to this kind of commentary – but not Black women. We know the quiet part spoken out…

Humans have an internal lunar clock. We are accidentally destroying it

Humans have an internal lunar clock. We are accidentally destroying it

PsyPost reports: Most animals, including humans, carry an internal lunar clock, tuned to the 29.5-day rhythm of the Moon. It guides sleep, reproduction and migration of many species. But in the age of artificial light, that ancient signal is fading – washed out by the glow of cities, screens and satellites. Just as the circadian rhythm keeps time with the 24-hour rotation of the Earth, many organisms also track the slower rhythm of the Moon. Both systems rely on light…

Cutting calories by 30% may be sufficient to shield the brain against aging

Cutting calories by 30% may be sufficient to shield the brain against aging

Science Alert reports: A calorie-restricted diet could slow down the aging that naturally happens in the brain as we get older, according to a new study of rhesus monkeys, and the findings could also be relevant to brain diseases such as Alzheimer’s. Researchers led by a team from Boston University analyzed the brains of 24 rhesus monkeys (Macaca mulatta) that had been fed calorie-restricted or standard diets for more than 20 years. After these lifelong dietary differences, the researchers found…

Eugenics: Child deaths projected to rise for first time this century, as aid cuts reverse decades of progress

Sara Herschander writes: The world is a much better place than it used to be, especially for young children. Insecticide-treated mosquito nets and novel treatments have made malaria much less deadly for millions of kids. Many countries now have the tools and techniques they need to nurse even very premature babies back to health. And the stupendous rise of vaccines against deadly diseases — like measles, diphtheria, and pneumonia — have prevented countless children from getting sick to begin with….

Long-term calorie restriction in diet may slow biological aging in the brain

Long-term calorie restriction in diet may slow biological aging in the brain

PsyPost reports: A new study suggests that restricting calorie intake over a lifetime may slow the biological aging of support cells in the primate brain. The research provides evidence that a thirty percent reduction in calories preserves the metabolic function of cells responsible for insulating nerve fibers. These findings were published in the journal Aging Cell. The brain relies on complex networks of communication to function correctly. This communication depends heavily on white matter, which consists of nerve fibers coated…

Study reveals the age at which you hit the ‘tipping point’ into frailty

Study reveals the age at which you hit the ‘tipping point’ into frailty

Science Alert reports: The bumpy trajectory of human aging may have a tipping point as we enter our twilight years, a new study has found. Past the age of around 75, our bodies can no longer easily recover from injury or illness – a sharp decline in resilience that comes with a corresponding rise in the risk of dying, according to researchers at Dalhousie University in Canada. Their model looks at aging as a balance between damage and repair, with…
