A genetic trick helps this all-female fish species escape evolutionary doom The Amazon molly, which reproduces asexually, has survived—and thrived—at least 10 times longer than predicted by evolutionary theory

Had a blast writing about the Amazon molly, a truly odd little fish that has defied evolutionary odds by reproducing asexually for at least 100,000 years. My latest for @science.org:

Titan might not have an ocean after all A reanalysis of data from NASA’s Cassini mission suggests Saturn’s icy moon may lack the subsurface ocean presumed for a decade

Saturn's largest moon, Titan, has been a member of the deep-sea club for almost 2 decades. New research might revoke its water world card. 🪐 🌊

Trump administration moves to break up leading U.S. climate and weather center White House budget director calls the National Center for Atmospheric Research a source of “climate alarmism”

“An abdication of U.S. leadership”—that's how the scientific and policy communities see the White House's push to dismantle the National Center for Atmospheric Research. 🌪️🪓

I'm glad you liked the piece! Thanks so much for sharing your research with me (and patiently explaining how it all works).

Have wild wolves learned to use tools? Video captures a lone female pulling crab traps out of the water, but does it count as tool use?

A female wolf has been doing something unusual on the Central Coast of British Columbia. She's learned to pull crab traps up from the water, yanking on a rope to bring it to the surface. But is it tool use? Very fun story from @phiejacobs.bsky.social for @science.org

Massive tropical bat is surprisingly family oriented, rare videos show New footage reveals spectral bats “hugging,” playing, and bringing food to their young

Spent the start of my week learning all about spectral bats, huge, carnivorous creatures who are shockingly sweet.

RFK Jr. Vowed to Find the Environmental Causes of Autism. Then He Shut Down Research Trying to Do Just That. While touting a $50 million initiative to identify the causes of autism, Robert F. Kennedy Jr. is helping lead an administration that is rolling back protections against pollution and toxic chemicals,...

Researchers slam HHS report on gender-affirming care for youth Critics say the report, which declines to disclose its authors, contradicts decades of scientific research

Researchers immediately condemned the recent HHS report on gender-affirming care for transgender youth, which declined to disclose its authors: “Scientists stand by their work. There is nobody standing by this thing.”

My recent story for @science.org

U.S. scientists’ lives and careers are being upended. Here are five of their stories As the second Trump administration sends U.S. science into upheaval, countless researchers are fighting for their futures

It was a privilege to help tell the stories of U.S. scientists whose lives have been upended during the first 100 days of President Donald Trump’s administration in this recent piece for @science.org

Researchers slam HHS report on gender-affirming care for youth Critics say the report, which declines to disclose its authors, contradicts decades of scientific research

Experts share scathing reviews of last week's HHS report on gender-affirming care for youth: "...a rejection of decades of science, evidence, and direct experiences by young people, their doctors, and their families.”

Crucial training pipeline for Deaf scientists dismantled by NIH funding cuts The one-of-a-kind initiative offered support from high school to postdoctoral levels

The Deaf Scientists Pipeline in Rochester, NY offers support for students and researchers from high school to postdoctoral levels. Now, due to NIH funding cuts, this one-of-a-kind initiative has been dismantled. My recent story for @science.org

FDA's proposed ban of electric shock devices has taken too long, autism advocates say With a new administration coming in, advocates worry that the FDA may lose its sense of urgency to ban electrical shock devices.

Disability rights activists have spent decades pushing the FDA to ban electric shock devices. The ban seemed on track for 2025 — until Trump won reelection. Now, people worry that Trump and RFK Jr's influence could delay the ruling. @statnews.bsky.social

Sara Reardon's story on the genetics of coat color in cats was a delight to read (and not just because my sweet calico, Mona Lisa, got to make her Science debut). Now I'm just waiting for scientists to make a discovery about tabbies, so Mo's brother Vinny can get his moment in the spotlight!
