Happy #FluorescenceFriday! 🔬🌟 Here’s a 4x expansion microscopy image with hoechst(🧬) and a NUP marker. The denaturation step made NUP marker non-specific, but also gave me a really cool image! #Mitosis #Microscopy

Why yes, we're parked over at @JCellBiol.bsky.social -- thanks for asking!

I will move to...

Moments before ICE broke this family apart. This is what family separation looks like 💔 This is heartbreaking and so painful to watch. I'm in tears. 😭

Donald Trump plans to declare a national emergency and utilize the Alien Enemies Act to conduct mass deportations. This xenophobia and cruelty shouldn't be allowed in America. We are going to fight it every step of the way.

Science twitter is dead! Long live science twitter! 🦋

Orii and Tanimoto @YCU_koho study the structural mechanics of #microtubule and #actin cytoskeletons using high-force intracellular magnetic tweezers. The measurements directly reveal the integrated nature of the two cytoskeletons throughout the cytoplasm hubs.la/Q02Yn83r0

When asked to draw a scientist, school-age kids in the United States are increasingly sketching women, according to a study from 2018. Read more on #STEMSTEAMDay: bit.ly/3CghCUd

Time to focus in and build community. Take care of the people who are more vulnerable around us to the best of our ability. I just can’t let hate and fear of those who differ from us win. I just can’t.

As a scientist, I know progress thrives on diversity & inclusivity. Now is the time to advocate for those whose voices are silenced, especially in the lab. Black, Brown, queer, trans, immigrant, undocumented, disabled, & Indigenous communities matter. We deserve to be here.

🚨 BREAKING- We are witnessing one of the most powerful revolutions in history. Ahoo Daryaei (آهو_دریایی), a courageous student at Tehran’s Science and Research University removed her clothes on campus in a fearless act of defiance after enduring harassment and assault by security forces enforcing mandatory hijab. Her bravery speaks for countless women who refuse to sit silently as their dignity and rights are trampled by a repressive system. We are gravely concerned for her safety- her fate remains unknown, and fears are rising. Share her story. #FreeIran #WomanLifeFreedom

Free scientific illustrations for biologists! 😍 @NIH has released a library of 500+ free scientific illustrations to create figures, presentations, and illustrations! all freely available in the public domain. Retweet and spread the message! bioart.niaid.nih.gov

You've spent 7 months writing your paper. The journal sent it back in 7 minutes for being over the word limit. 9 word-cutting secrets for academic papers (Most professors won't tell you about No 7)

@amina_haddadhr @DaniBeckman Thank you so much 🥹

Dreaming of the day we will be able to make neurons undergo mitosis like this and generate healthy new neurons to replace the lost or impaired ones.

Earlier this year on International Day at Bunker Hill Elementary, we celebrated Chile’s culture with Amigos de Cultura de Chile! 🎉 Blanca Pasten captivated everyone with her Mapuche dances, honoring fire, wind, nature, and the land. 🌿 #internationalday #dancehouston

💜🌟#PoTSAwarenessDay🌟💜 #PoTS is so much more than just a fast heart rate upon standing! Quality of life can be equivalent to COPD and congestive heart failure. Many patients are told that their physical symptoms are ‘all in their head’ and instead are given psychiatric labels of #anxiety & #depression. Triggers: viruses, bacterial infection, pregnancy, surgery, a traumatic event, immunisation, hypermobility. Symptoms: potsuk.org/about-pots/sym… Managing PoTS: potsuk.org/managingpots/ Please view our website for further information: potsuk.org #MedTwitter #TeamGP #MECFS #LongCovid #postviral @DrSdeG @jtrebach @nursekelsey @WeCYPnurses @LWNurses @DrDerekConnolly @BinitaKane @Daltmann10
