The Pedaliaceae go in for trample burs, which attach when trod upon. Here’s another: Sesamum eriocarpum (formerly Dicerocaryum e.). This prostrate plant has discoid fruit with 2 sharp points—perfect for sticking into hooves of animals. 📷: tjeerd CCBYNC4 #Pedaliaceae #epizoochory #Botany 🌾🧪🌱

I haven't even met (many of) the world-famous students yet. SLAC positions were never really on my radar; a consequence of my own personal history & training. But now that I'm here, I can see how a SLAC like Grinnell offers many benefits, especially given higherEd 2026. DM me❓ 🧪 #HBES #EHBEA

What mechanisms underlie health benefits of social interaction? @ryssamoffat.bsky.social @introspection.bsky.social @escross.bsky.social show that neural synchrony during a creative drawing program decreases in intergenerational dyads, increases in same-generation @plosbiology.org 🧪 plos.io/4gbafyY
An intergenerational dyad draws together. Without prompts and through collaboration, they create shared drawing. While they draw, their brain activity is recorded using mobile sensors and their body movements are tracked using video-based motion capture. Photograph captured by Ryssa Moffat. The participants depicted in this photograph have provided written consent for their likeness to be published alongside open-access online research outputs.

Bacillus cereus #hemolysin BL (HBL) uses host receptors LITAF and CDIP1 for #cytotoxicity, but the loss of both only partially protects the host. This study shows that Caveolin 1 completes a 3-factor host system whose combined loss confers full resistance to HBL @plosbiology.org 🧪 plos.io/4xTXe2A
Left: Co-localization (yellow) of HBL-B (green) and CAV1 (red) on HT1080 cell surface. HT1080-WT, HT1080-dKO, and HT1080-tKO cells bound with HBL-B were stained with an anti-HBL-B antiserum (green) and an anti-CAV1 antibody (red). Merge images highlight co-localization (yellow) of HBL-B and CAV1. DAPI-stained nuclei (blue). Scale bar = 25 μm. Representative of three independent experiments with similar results. Right:  In vivo role of CAV1 in HBL pathogenesis. Mice with indicated genotypes (WT, Cav1−/−, Litaf−/−/Cdip1−/− (dKO), Litaf−/−/Cdip1−/−/Cav1−/− (tKO)) were challenged with 2 µg HBL toxin (I.P. route) daily as indicated by red arrows. Of note, while all the Litaf−/−/Cdip1−/− (dKO) mice succumbed to 2-3 doses of HBL, the Litaf−/−/Cdip1−/−/Cav1−/− (tKO) mice were completely resistant to the HBL challenge that all the mice survived even with 5 doses of 2 µg HBL toxin challenge.

✨New Account I've started drawing editorial cartoons about space ethics, because apparently writing only works if people read. If you like space with a side of “have we really thought this through?”, please follow. Reposts, likes etc would help this new account lift off. Y'all know the drill. 🙏🏻 🔭🧪🐡

Happy #MicroscopyMonday! Here's some #SciArt of a confocal micrograph stylized using the Ps emboss filter. See the thin projections extending between the 2 cells? They're #cytonemes! 🔬 How do they find each other? Follow postdoc @itsscientistsam.bsky.social to learn more 🧪 👩‍🔬

Forecasters are expecting a ‘super’ El Niño to form, and Nature reports how some scientists fear it could push the Amazon rainforest past its tipping point and into irreversible decline. 🌎🧪
A ‘super’ El Niño could transform the Amazon. Is the world’s biggest rainforest doomed?

A ‘super’ El Niño could transform the Amazon. Is the world’s biggest rainforest doomed?

The Amazon rainforest might be closer to a tipping point than scientists thought. Some fear that droughts and fire could nudge it into irreversible decline.

The study has been published in The New England Journal of Medicine. YES, it is PEER-REVIEWED. • www.nejm.org/doi/full/10.... • clinicaltrials.gov/study/…. • physicianresources.dana-farber.org/news/ras-on-... 🧪🧵⬇️
KEY POINTS
•A Phase Ill clinical trial has demonstrated that daraxonrasib significantly improved overall survival and progression-free survival compared to chemotherapy in patients with advanced pancreatic cancer.
• It was the first large, randomized trial evaluating a RAS inhibitor to treat pancreatic cancer, one of the deadliest cancers.
•RAS inhibitors, which target cancer-driving mutations once thought to be undruggable, bring new hope to patients with some of the hardest-to-treat cancers.
Summary 

Current therapies offer limited benefit for patients with previously treated metastatic pancreatic ductal adenocarcinoma (mPDAC). Whether daraxonrasib — an oral RAS(ON) multi-selective, tri-complex inhibitor of the active guanosine tri-phosphate-bound state of mutant and wild-type RAS - can improve survival outcomes is unclear.
HOW WAS THE TRIAL CONDUCTED?
Adults with previously treated mPDAC were randomly as-
signed to receive daraxonrasib at a dose of 300 mg once daily or chemotherapy of the investigator's choice. The dual primary end points were overall survival and progres-sion-free survival in the subpopulation of patients with RAS G12 mutations.
TRIAL DESIGN
• Phase 3
• Open-label
• Randomized
• Location: 59 sites in six countries
RESULTS
In the RAS G12 population, the median overall survival was significantly longer with daraxonrasib than with chemotherapy (13.2 months vs. 6.6 months), as was the median progression-free survival (7.3 months vs. 3.5 months).
In both the RAS G12 population and the overall popula-tion, treatment with daraxonrasib reduced the risk of death by 60%. Adverse events of grade 3 or higher occurred in 61.8% of the patients in the daraxonrasib group and in 69.6% of those in the chemotherapy group. The most commonly reported treatment-related adverse events in the daraxonrasib group were rash and diarrhea.
LIMITATIONS AND REMAINING QUESTIONS
• The open-label design may have influenced adverse-event reporting and treatment modifications, as well as the decision by some patients in the chemotherapy group not to begin treatment after randomization.
• Subgroup analyses were exploratory and may have been limited by small sample sizes.
CONCLUSIONS
Among patients with previously treated mPDAC, treatment with daraxonrasib led to significantly longer overall survival and progression-free survival than chemotherapy.

"Using generative AI inherently exposes you to the risk of career-ending accusations of plagiarism." "That means that all of us [on multi-author papers] have the ability to end each other’s career. " Full marks to the Carlson Lab for their blanket ban on the use of generative AI for writing! 👏🧪

This piece is great and I wish to staple it to several scientists' foreheads. And while it's about the creation of text, I think it also applies to writing codes, since many (for example, cosmological) codes are publicly available, which means LLMs have vacuumed them up.

A significant amount of 21st century research focuses on systems (e.g., genomic, cellular, organismic, and ecological/global). Systemic Darwinism is emerging in this context. Systemic Darwinism🧪 pmc.ncbi.nlm.nih.gov/arti….

1/10 TON 618 is an enormous #quasar, a type of extremely luminous active galactic nucleus (AGN) at the center of a #galaxy.🔭 Its engine is one of the most massive black holes known. QSO 1228+3128 is one of its alternative designations.⚛️🧪 #cosmology #universe #astronomy
A large dark circular silhouette fills most of the frame, edged by a thin glowing orange ring that looks a bit like a halo against a starry black background. White text near the top reads “TON 618” and blue text reads “2606 AU Diameter.” In the exact centre a minuscule point, highlighted by a white arrow, marks the approximate size of our solar system, about 80 AU across, so small it almost vanishes inside the huge black circle.

When we find complexity in nature, evolutionary theories tend to burn other explanations and reshape them into their own, unreasonably effective image ;-) Earth’s Organisms Developed Via Evolution. Some Theorists Wonder: What if the Entire Cosmos Did, Too?🧪 www.smithsonianmag.com/sc….
According to a niche perspective called “cosmological evolution,” universes may reproduce by spawning black holes in which new universes may form. The concept is far from proven, but researchers note its potential.
