Mixing is a fundamental process that functions like a heartbeat for lakes. But at iconic lakes around the world, climate change is slowing or even stopping that heartbeat - causing profound impacts to these very special ecosystems. @quantamagazine.bsky.social www.quantamagazine.org/mixing-is-th...

Should aging be considered a disease? Some scientists argue that this would accelerate anti-aging research; others say it makes no biological sense and would be fraught with ethical implications @nature.com www.nature.com/articles/d41...

It's hard enough to get people interested in reading these days, but this is a new low. A book club wants to feature my book - but only if I "tip" each reader $15-30 "to recognize [their] effort." Is this a thing now??

After 263 African elephants were moved from one national park to another, the animals began wandering out - destroying property and killing people. My latest for @biographic.bsky.social, on the complexities of conservation in an increasingly crowded continent. www.biographic.com/the-wild-ele...

Psychedelic mushrooms evolved their magic twice, in two distantly related groups of species. What's more, those mushrooms take radically different biochemical routes to producing psilocybin. www.nytimes.com/2025/10/18/s...

A Taiwanese- and Chinese-run Buddhist orphanage in Malawi is recruiting vulnerable children into the illegal wildlife trade. Behind it all is a Chinese ivory kingpin who Malawian officials are about to release early from prison. @economist.com www.economist.com/1843/2025/10...

In infants, a healthy gut microbiome is key for developing a healthy immune system. But in the U.S., 75% of babies are deficient in critical types of bacteria, and these babies are more likely to development of asthma, allergies and eczema as toddlers. bit.ly/4lK1Mmd

Cuts to science funding by the Trump administration are set to negatively affect all Americans. One group most impacted, though, are science students and early-career researchers who are being robbed of their future. @sciam.bsky.social www.scientificamerican.com/article/how-...

The Senate's new bill would cut $1 trillion from Medicaid, causing 10+ million people to lose insurance. Cancer patients are one group set to suffer (and needlessly die) the most. 1 in 10 adults and 1 in 3 children with cancer depend on Medicaid. www.thinkglobalhealth.org/article/canc...

Eagles are sacred to Native Americans. But poaching and trafficking of eagle feathers is on the rise, thanks to the powwow industry & the increasing popularity of peyote ceremonies. In Oklahoma, two fiery Comanches are trying to do something about it. @audubon.org www.audubon.org/magazine/nat...

“I think we will build a sustainable future,” Wagner says. “But it’s going to take 30 or 40 years, and by then, it’s going to be too late for a lot of the creatures that I love.”

Continuing the birds-are-awesome theme: Hummingbirds in California have evolved new beak shapes and massively expanded their range—thanks to feeders. They've basically become the equivalent of backyard pigeons! @science.org www.science.org/content/arti...

Human preference for smooshed, baby-like faces has produced pedigreed cats and dogs that are more similar to each other than to their wild relatives, and have such distorted skulls that they could not survive in nature. www.scientificamerican.com/article/bree...

Yet more evidence that birds are awesome: Flamingos harness the physics of fluid flow to create vortices that sweep up prey and funnel it directly into their mouths. www.nytimes.com/2025/05/12/s...

A leading vaccine researcher's top new worries for the future: 1) lots of people, especially children, are going to die 2) we're going to lose a generation of new scientists, because who wants to go into a career that's actively being condemned @nymag.com nymag.com/intelligence...

It wasn't long ago that sleeping sickness infected 40,000 people a year. Now, infections are down to less than 1,000/yr, thanks to a concerted effort of a small international team. But those last cases will be the hardest to stamp out. @nature.com www.nature.com/articles/d41...

Multiple studies are in the works to see whether and how autistic people could benefit from psychedelics. Testing how this specific group of people responds to treatment is important, because autistic brains differ from neurotypical ones. @science.org www.science.org/content/arti...

The human brain is sometimes called the most complex machine in the universe - but we wildly overestimate it. It outputs thoughts at a ridiculously slow 10 bits per second, and all the knowledge it can store could fit on a small thumb drive. www.scientificamerican.com/article/the-...

A man in Florida was tragically killed after his surgeon mistook his liver for his spleen (and then tried to cover the mistake up). These kinds of egregious medical errors - called "never events" - are more common than you might think. @nymag.com nymag.com/intelligence...
