Today the FDA removed the "black box" warning labels from hormone therapy for menopause. Here's what that means, and why the risks—and benefits—of HRT might be overstated. By me and @laurenjyoung.bsky.social @sciam.bsky.social www.scientificamerican.com/article/fda-...

🚨 BREAKING: Canada has lost its measles-free status after a year of continuous transmission — meaning the Americas region is no longer measles-free. What does this mean? My story for @sciam.bsky.social 🧪

Clinicians are noticing a steady climb in diagnoses of ARFID, a type of eating disorder that presents as a food avoidance so persistent and pervasive it can cause severe malnutrition in kids and adults. More @sciam.bsky.social: www.scientificamerican.com/article/what...

With all the fuss over tylenol, we're missing a bigger issue: we don't know enough about medication safety in pregnancy because so few drug studies include pregnant people. And that harms both women and their fetuses. My latest @sciam.bsky.social www.scientificamerican.com/article/what...

I spoke with 2025 Nobel winner Shimon Sakaguchi about chasing regulatory T cells since the 1980s. His advice to early-career scientists: "Nowadays you are expected to do something very, very soon and have a result. But it always takes time to arrive at something important." @sciam.bsky.social

On today's Science Quickly, I interviewed a former White House doctor about the president's care, aging and more: "It is a fact of science, it's not a political attack, that humans past the age of 60... start to have cognitive decline." "We have a gerontocracy." Listen on @sciam.bsky.social 🎧

Updated COVID vaccines are still the best tools we have to reduce severe disease and death from the virus. @sarafnovak.bsky.social explains the latest research for @sciam.bsky.social. www.scientificamerican.com/article/new-...

Six of the nine Nobel Prize winners this year work in the U.S. Three of the six were born outside the U.S., which is the pattern most years. No country has benefited more from welcoming immigrants from around the world. www.nobelprize.org

welp, you get what you ask for. joking with coworkers that it's going to be mofs, and i'm really a med chem type so will i be able to do this and lol here it is. the Nobel Prize for chemistry for 2025 goes to the development of metal-organic frameworks. www.scientificamerican.com/article/2025...

Now on @sciam.bsky.social: This year’s physics Nobel goes to 3 researchers who demonstrated quantum tunneling on a superconducting chip. By bringing this microscopic effect into the macroscale world, they laid important foundations for quantum computing. www.scientificamerican.com/article/2025...

It's Nobel week! Here's @laurenjyoung.bsky.social with a great explainer on the science of today's winners, who developed our understanding of how the immune system avoids attacking the body: 🧪 www.scientificamerican.com/article/2025...

This year's #medicineNobel was awarded to Mary E. Brunkow, Fred Ramsdell & Shimon Sakaguchi for discovering why the body doesn't attack itself—key for organ transplants and autoimmune disease therapies. By @laurenjyoung.bsky.social for @sciam.bsky.social: www.scientificamerican.com/article/2025...

The 2025 Nobel Prize in Medicine goes to some neat fundamental research on the immune system: peripheral immune tolerance. It's what keeps the body's defense mechanism in check—and could be key to new therapies for autoimmune disorders. @sciam.bsky.social www.scientificamerican.com/article/2025...

“I think chimpanzees have helped people understand that we are part of and not separated from the animal kingdom, and that has opened the way to having respect for the other amazing beings with whom we share the planet.” —Jane Goodall, @sciam.bsky.social www.scientificamerican.com/article/jane...

Jane Goodall is an inspiration to so many in science, myself included. I once combed through @scifri.bsky.social's archives listening to her interviews. I'll never forget her on-air imitation of a chimp pant-hoot. A true legend 💙🐒 www.youtube.com/watch?v=0t8_... www.sciencefriday.com/articles/arc...

"You see CDC being torn apart, 2,000 people who are no longer there, years of experience, centers that are being demolished." @drdemetre.bsky.social discusses the dire state of US public health w/ @feltman.bsky.social on @sciam.bsky.social Science Quickly: www.scientificamerican.com/podcast/epis...

Well not only is TS Imelda going to move away from the U.S. (phew), it's doing so because of what is essentially a "flavor" of the Fujiwhara effect that has Imelda making a sharp right turn to follow in Hurricane Humberto's wake. 🧪 (I love hurricanes.) www.scientificamerican.com/article/how-...

The FDA is conducting "its own review of the evidence" on the safety & effectiveness of abortion drug mifepristone, according to news reports. Yet a wealth of evidence has shown the drug is safe and effective. SCOTUS rejected a case on this last year: www.scientificamerican.com/article/abor...

Measles can lay dormant for years and come back as a rare but deadly brain disorder. The recent death in a child is a reminder that widespread MMR vaccination is important in protecting people who cannot be vaccinated. @andreatweather.bsky.social explains: www.scientificamerican.com/article/meas...

Did a rare stint on the health desk and wrote about a complication of measles that can lead to a fatal brain disorder years after the infection, underscoring why widespread vaccination is so important. The child that died was too young to be vaccinated when the contracted measles. 🧪
