A most beautiful #sunrise looking over cliffs of #Medeira. No crowds here and still a breathtaking start to the day.

Congratulations Professor!!

A South American lungfish against a black background, with text: This odd fish has 30 times as much DNA as humans—a new record for animals.

A species of lungfish found in South America has claimed the title of the animal with the biggest genome sequenced so far.

Genomic inference of a severe human bottleneck during the Early to Middle Pleistocene transition A severe bottleneck that brought human ancestors close to extinction occurred between about 930 and 813 thousand years ago.

Between 800,000 and 900,000 years ago, the population of human ancestors crashed, a 2023 Science study finds.

The results suggest there were only ~1280 breeding individuals during the transition between the early and middle Pleistocene. https://scim.ag/3K4hcnC #ScienceMagArchives

A new study reveals a signaling loop that drives metastasis in triple-negative breast cancer, discoveries about amylin receptor subunits could inform future drug design, and more this week in #ScienceSignaling. https://scim.ag/3HH1ePw

One may demand increased usefulness of animal experiments, but to stop funding for grants with only animal experiments may not bring any value for either animal well-being (for the point you mentioned) or for human health (organoids will be ineffective in capturing multi-organ crosstalk).

Time to transmute and grow even more.

“GlycoCaging” uses gut bacteria to activate drugs for inflammatory bowel disease.

Type 2 cytokines act on enteric sensory neurons to regulate neuropeptide-driven host defense Enteric nervous system (ENS)–derived neuropeptides modulate immune cell function, yet our understanding of how inflammatory cues directly influence enteric neuron responses during infection is conside...

Completing the circuit? Enteric neurons produce immunomodulatory neuropeptides. It seems that they also express cytokine receptors and that cytokine signals promote neuropeptide production by them. The study shows the importance of this crosstalk in helminth control.

Students:
Reading is not a project. Definitely not a summer project.
That's what students do.
Just like breathing is what living organisms do.
@treelab.bsky.social there are no reading projects, but you can borrow books, or we can direct you to the aisle in the #iiserbhopal library.

Gene behind orange fur in cats found at last After 60 years, scientists know why gingers, calicos, and tortoiseshells look the way they do

After 60 years, scientists finally know why ginger, calico, and tortoiseshell cats look the way they do. scim.ag/3BpxRxY

Trace DNA from kill sites identifies individual predators Predation ecology and evidence-based conflict management strategies require reliable and accurate identification of individual predators. Identifying …

Hi

Global pandemic treaty finalized, without U.S., in ‘a victory for multilateralism’ Three years in the making, the accord aims to increase equity and avoid errors of the COVID-19 pandemic

It took an extension to the extension of the extension, but after more than 3 years of negotiations, governments around the globe—but notably, not the United States—have finally agreed on a treaty to improve how the world prevents, prepares for, and responds to future pandemics. scim.ag/4lDYcLe

Two positions in the @TrEE_Lab
Looking for students who are interested in genomic work & have basic training in handling genomic data. If you have a penchant for coding, writing scripts, & an interest in solving population genetic patterns in plants, apply! April 15th deadline.

#Immunology out now @science.org

After initial priming in the lymph nodes, mouse CD8 T cells undergo a second phase of stable interactions with dendritic cells that can preferentially stimulate those with a high-affinity for antigen.

wow....

dogma indeed!!

wonderful read for today!

A lupus-derived autoantibody that binds to intracellular RNA activates cGAS-mediated tumor immunity and can deliver RNA into cells Delivery of autoimmune disease–associated antibodies activates the immune system to fight glioblastomas.

I wouldn't have anticipated a Lupus self-directed antibody (4H2) might someday turn out to be an anti-cancer treatment

Pyruvate metabolism enzyme DLAT promotes tumorigenesis by suppressing leucine catabolism Wang et al. reveal that DLAT, a pyruvate metabolism enzyme, modulates leucine metabolism by directly acetylating the leucine catabolism enzyme AUH at K109, leading to leucine accumulation and sustained mTOR activation in HCC. Restoring leucine catabolism…

This has only been possible through NIH funding.

Funding biomedical science through the NIH has been one of the greatest accomplishments of the United States of America for America, and for the world.

We are ALL better for the work that passionate scientists funded by the NIH have been able to do.
