Peptides promise longevity and healing. Does the science back them up? The world of peptides has exploded in wellness circles, but the benefits of injecting these gray-market molecules rest on little clinical evidence

Are you on a “Wolverine stack”? A “glow” stack? If you know what those terms mean, you’ve stepped into the world of peptides, an unregulated Wild West of wellness. @beebrookshire.bsky.social has the story @sciam.bsky.social www.scientificamerican.com/article/the-... 🧪

Congress grills RFK, Jr., about vaccines and cuts to health budget The HHS secretary defended proposed budget cuts to science, his vaccine moves and health care costs on Capitol Hill on Thursday

RFK, Jr., is in the hot seat today for the first of 7 congressional hearings. Congress is grilling him on health care budget cuts, his vaccine record, fraud allegations and more. @danvergano.bsky.social has the story @sciam.bsky.social www.scientificamerican.com/article/cong...

Do allergies decline with age? What the research shows Do declining immune systems explain the trend, or is something else going on? Experts explain

Spring pollen got you down? Surprisingly, older adults have fewer seasonal allergies than younger adults do. And it's not just because the immune system declines with age (although it does). Matt Fuchs has more @sciam.bsky.social www.scientificamerican.com/article/why-...

Three parachutes and a space capsule against dark blue ocean.

🌎 NASA's Artemis II mission has splashed down and all four astronauts are reported safe, bringing an end to a stunning flight around the moon. www.scientificamerican.com/article/nasa...

“We see three good-looking parachutes,” Jacki Mahaffey of mission control told the astronauts.

What a beautiful Artemis II landing. 🧪

Update: The crew splashed down off the coast of San Diego, Calif., around 8:07 P.M. EDT: www.scientificamerican.com/article/nasa...

NASA’s Artemis II launches on first crewed moon mission of the 21st century A daring 10-day voyage will take four astronauts on a loop around the moon and set the stage for future forays to the lunar surface

Now on @sciam.bsky.social: Artemis II is truly underway, with main engine cutoff & other launch milestones in the rearview. Soon, our planet will be in the rearview too, as tomorrow the mission embarks on its voyage to the moon. By @nadiadrake.bsky.social

A new COVID variant is spreading in the U.S. How worried should you be? Infections of the BA.3.2 variant of the COVID-causing coronavirus are still at very low levels, but experts are concerned it may be resistant to immunity from vaccines or prior infection

Here's what you need to know about Cicada, the new(ish) covid variant spreading in the U.S. @sciam.bsky.social www.scientificamerican.com/article/new-...

One week - and that's more than the entirety of the US public health budget up in, literal, smoke.

The kids are all right Surprising studies show young people are doing better than previous generations in many ways

Sure, there are areas like social media use that can pose risks. But for the most part, kids today are actually functioning better on “soft skills” like social and emotional development. So all you parents, take heart! Read the story in our new issue: www.scientificamerican.com/issue/sa/202...

The dominant narrative is that young people are struggling much more than previous generations, but that’s not what most data suggests.

The kids are all right Surprising studies show young people are doing better than previous generations in many ways

In our latest SciAm issue, Melinda Wenner Moyer explores a topic that is newly resonant with me: whether today’s kids are “all right”—socially, emotionally and mentally. www.scientificamerican.com/article/the-...

Judge temporarily blocks key parts of RFK, Jr.’s effort to overhaul U.S. childhood vaccines A federal judge on Monday issued a stay on the CDC’s move to reduce the number of routinely recommended childhood vaccines

My first for @sciam.bsky.social, where I write about a vaccine in the works against the most common cause of traveler's diarrhea. Many thanks to @tanyalewis.bsky.social and @sarahexplains.bsky.social for editing and considering the story!

Author @michaelpollan.bsky.social has spent decades exploring what it means to be human. In his new book A World Appears, he takes on one of the biggest questions in science and philosophy: what consciousness is—or isn’t. Hear more: www.scientificamerican.com/podcast/epis...

Trump’s State of the Union speech made no mention of Make America Healthy Again On Tuesday the U.S. president largely steered clear of his administration’s health care agenda amid a broader push to downplay antivaccine efforts ahead of upcoming midterm elections

Trump’s state of the union speech, despite being record-long, did not once mention his administration’s Make America Healthy Again effort - a notable omission that may reflect concerns about a backlash in the midterms to RFK’s antivaccine policies: www.scientificamerican.com/article/trum...

The surprising new physics of squeaky basketball shoes A new study explains why basketball shoes make a high-pitched squeaking noise when they rub against the hardwood. The ridges on the sole hold the key

Now on @sciam.bsky.social: Why do basketball sneakers squeak so much?

Come for the surprising explanation based on a new study; stay for the demo showing how, in principle, shoes could be made to squeak out Darth Vader's "Imperial March" on the court!
