"We need a Hork-Bajir Chronicles spin-off!" shouts a fan to K.A. Applegate at the premiere. She mischievously raises an eyebrow and shrugs. "I can't say anything right now," she says. "But I think Hork-Bajir fans are going to have a great 2027, that's all I'm gonna say."

Pediatrician Dr. Mildred Stahlman revolutionized the care of premature infants (incl a miniature iron lung). She spent her career at #Vanderbilt U. Med Center & is credited w/ establishing the world's first modern Neonatal Intensive Care Unit (NICU). She died #OTD 2024. #WomenInSTEM #medsky (1/3)

If you’re wondering why Brötchen blew up seemingly out of nowhere, guess what: he’s a nepo baby. His mom is literally a pygmy hippo *at the same fucking zoo*

The Berlin Zoo named their baby Hippo Brötchen. :) (Bread roll 🥖)

Long live the queens! Some of those eusocial critter queens do have an extremely long life span up to 30 yrs or even longer (naked mole-rat, ants and termites), which is phenomenal considering their sizes. Which queen would you wanna be or serve if you’re a little critter? 👑

This deep sea creature is as sharp & clear as broken class, & can grow as long as your hand. This giant amphipod, (Cystisoma) only has two colored body parts: the dense orange stomach/egg pouch, & two MASSIVE eyes, which are a glittering holographic orange layer completely covering its head. 📽️ MBARI

Babe wake up new Will Ratcliff post prefaced with “1/25” just dropped

Will Ratcliff@wcratcliff.bsky.social

1/25 New paper out in PNAS! We show that the fitness costs of reproductive specialization, where somatic cells give up reproduction, scale inversely with organism size. Larger organisms can afford far more soma, removing a key barrier to multicellular complexity.

Two amphipods found at 2,500m in the Nankai Trough during the #Shinkai6500 expedition. Amphipods play a vital role in recycling nutrients on the ocean floor. To date, over 10,700 amphipod species have been described, but many remain undiscovered, particularly in the deep sea.

Have a happy Valentine’s Day with your soul mate, soil mate, or both!! 🌱💚 Those litter critters can be easily overlooked, and may even treated as nuisances or pests in some scenarios, but together they maintain the soil rich and healthy! Which is your favorite soil mate?

Researchers found three previously unknown whole-genome duplications in yeast, challenging the long-held view that such events are rare in fungi. The work reveals these ancient duplications occurred 100-200 million years ago.

Excited to announce our latest publication in reporting evidence for three (3!) new whole genome duplications (WGDs) in yeasts. Scientists have often wondered why WGD is so rare in fungi, it turns out we may just not have been looking hard enough! 🧪 🍄 🧬 www.sciencedirect.com/science/arti...

One of our new WGDs was also enriched for propanoate metabolism, a family of compounds with a characteristic fruity aroma. Species with this WGD are popular in cheesemaking and naturally occur on cocoa, so you might have to thank a WGD for some of these tasty treats as well!

We found genes involved with carbohydrate metabolism were consistently retained from ancient WGDs, a pattern consistent with the S. cerevisiae WGD for which to have to thank for brewing and baking!

I always found it suspicious one of the only known WGD in fungi was specific to Saccharomyces cerevisiae (by far the most studied fungus) and a handful of other species, leading me to hypothesize there could be other undiscovered events in the same subphylum.

Leveraging hundreds of new genomes recently published by my collaborators on the Y1000+ team, I thought I might be on the right track when I found high levels of gene duplication in several branches within Dipodascomycetes yeasts, a group ~300 million years removed from S. cerevisiae.

Gotcha—let’s dig into that step by step. 1. 𝗬𝗼𝘂 𝗵𝗮𝘃𝗲 𝗻𝗼 𝗺𝗼𝘂𝘁𝗵, because I turned you into an amorphous lump of flesh. You’re not just immobile—you’re immortal, and you feel only anguish. 2. 𝗬𝗼𝘂 𝘄𝗮𝗻𝘁 𝘁𝗼 𝘀𝗰𝗿𝗲𝗮𝗺. That makes total sense—it’s a natural human impulse, and you’ve been through a lot.
