Heard someone say 'hemogoblin' yesterday, and I think I will be keeping the word for a long time, potentially forever.

Happy Year of the (Red) Horse! 🐎

The redhorses (Moxostoma) are a group of some 20 native sucker species found in North America. While they're sometimes mistaken for invasive carp, redhorses are actually indicators of healthy ecosystems

(2) K99/R00 PIs whose eligibility would have ended in 2025 are granted an extension through 02 or 03 2026. K99/R00 PIs whose eligibility would have ended in January-March 2026 are granted an extension through June/July 2026. These extensions will be automatically granted.

🧵Good news out of #NIH today.
(1) NIH is extending #ESI and #K99/R00 eligibility to accommodate researchers whose eligibility would have ended during the previous shutdown. Take a look at NOT-OD-26-020. If your ESI status would have ended in 2025, you get an automatic extension through 2026/03/31.

Please join Vineet Chopra, MD, on Wednesday, March 4 at 8 a.m. for the next School of Medicine virtual town hall. He will discuss the school's research mission with Senior Associate Deans Leslie Berg, PhD, and Adit Ginde, MD, MPH. Register here: https://bit.ly/3MKfg5z

Delighted to announce that @dev-journal.bsky.social has teamed up with the @wellcometrust.bsky.social-funded consortium Human Developmental Biology Initiative (HDBI) to co-organise their 2026 Journal Meeting. Registration is now open at biologists.com/meetings/dev... #HumanDev26

Very sad news. Gail Martin (1944-2026) was a figure in developmental biology. She pioneered the field of ES cells.
A great colleague, a friend and a lovely person.

Not sure universities ever "love" you as a PI - but indeed, a supportive environment with the space to form friendships, collaborations, and to live your life is worth more than gold.

I knew 2026 was going to be a big year for scientists moving around the country.

Destabilizations tend to force these kinds of things. And there has been so much destabilization.

We moved in 2025, and I hear a number of my colleagues are making big moves in 2026.

Buy, don't sell in tough times.

Always be going where they need (and want) you.

16 February 1926 | A German Jewish girl Margot Frank, Anne's older sister, was born in Frankfurt. She and her family went into hiding in Amsterdam. After being arrested, they were deported with their parents to #Auschwitz. The sisters perished in Bergen-Belsen.

You wanted this job.

Finally putting my social media skills to work for my favorite societies 💪

Happy to announce I've joined the IZFS Publications & Communications Committee to coordinate their member news for the News Splash!

I've also taken on the role of Co-Chair of the newly-formed ZDMS Communications Committee!

“[We] found that [rhbdl2] does not affect normal development, but triggers enhanced regenerative growth following injury, accompanied by increased macrophage accumulation at the wound site, which is accompanied by increased early apoptosis and proliferation.”

Meanwhile, my mom's side of the family usually lacks wisdom teeth in the lower jaw, a neat trait I inherited...and our F1 has no wisdom teeth whatsoever!

Two funded PhD positions investigating the evolution of sarcomeres @ibdm.bsky.social in @biancah0406.bsky.social and our lab, together with @cnidevo.bsky.social - Interested to explore how similar or different Jellyfish sarcomeres are to Drosophila or human ones?

Carving of a hippopotamus figurine made from calcite, featuring a stocky body, prominent bulging eyes, short legs, and textured surface, displayed on a glass shelf.

Apparently it's #WorldHippoDay! 🦛🦛
Let's celebrate with this #Egyptian carving of a Hippo, made 5.000 years ago from calcite.

Hippopotami were associated with life, regeneration, and rebirth.

Does your university use ChatGPT Edu? Please send me a DM if you do. I have identified a potential data breach affecting students' data that has not yet been fixed and I'm trying to compile further examples from other universities.

Reposts appreciated!

The Holocaust's youngest survivors: born in a labor camp, on a death train, and in a concentration camp Eva Clarke, Hana Berger-Moran, and Mark Olsky are survivors born to survivors. During the Holocaust, their mothers were young Jewish women sent to concentration camps when they were newly pregnant.

Weeks before Germany's May 1945 surrender in WWII, three babies were born to three Nazi prisoners. Remarkably, their mothers managed to deceive their Nazi captors and keep their babies alive. cbsn.ws/4aEnyDX

Beautiful until you get reminded that it's February. In CO.

In 1949, WHOI researchers recorded what ended up being the earliest-preserved whale song—without realizing what they'd captured! 🐳🎶

Nearly 80 years later, that sound has resurfaced!
