Wonderful to see this beautiful image on the cover of Science this week highlighting a paper that uses high resolution imaging to show the spatial patterns of bacterial attraction to glutamine from roots.

As the Moon eclipsed the Sun on 8 April 2024, birds took note.

Leveraging nature’s own experiment, scientists and the public joined forces to show how different species responded to sudden midafternoon darkness followed by a new “dawn.” Learn more this week in Science: https://scim.ag/48WbhLL
As the Moon eclipsed the Sun on 8 April 2024, birds like these rock pigeons (Columba livia) took note.

In a new Science study, researchers show that lysosomes, degradative organelles activated by food limitation, stimulate epigenetic changes that contribute to transgenerational longevity in C. elegans.

From lysosome to longevity: Overexpression of the lysosomal lipase LIPL-4 in Caenorhabditiselegans results in methylation of lysine 79 on histone H3 (H3K79),which increases transcription of the gene encoding histone variantHIS-71. HIS-71 is shuttled from intestine to oocytes through association with yolk particles. On arrival, it is methylated and becomes associated with germ line DNA. These events promote longevity in wild-type descendants for several generations.

I love these new layers of complexity that people are discovering in the brain! Dendrites of different neurons can connect via nanotubes, which transport calcium and cargo such as amyloid-beta www.science.org/doi/10.1126/...
Hidden networks in the brain
Dendritic nanotubes extend brain connectivity beyond synapses

This paper does a great job with a "It's a Wonderful Life" scenario about NIH, supposing the consequences of the bottom 40% of the funding NIH grants never existed.

www.science.org/doi/10.1126/...

tl:dr The world would lose a lot, but directly and indirectly
What if NIH had been 40% smaller?
Replaying history with less NIH funding shows widespread impacts on drug-linked research

Science just published two important (imo) #genomics papers about the origin, mobility and pesticide resistance of Aedes aegypti, funestus and formosus mosquitoes - and the increased risk of dengue and malaria.

also really fun to share an issue and a commentary with a big paper on Aedes aegypti 🦟🥂🦟

congrats @mariloumercedes.bsky.social and Jacob E. Crawford

Very cool study by @oyiz.bsky.social using optogenetics to shed light on how oxytocin signaling regulates vocalization to maintain maternal bonds (with nice write-up by @bellonec.bsky.social, “Cries into ties” indeed) 🧪

The photosystem I and light-harvesting proteins of marine coccolithophores assemble into a huge molecular machine that efficiently captures, transfers, and converts light energy, demonstrating the evolutionary diversity of photosynthesis.

The photosynthetic proteins of marine coccolithophores capture green light underwater and appear orange-red. Their photosystem I and light-harvesting proteins assemble into a huge molecular machine that efficiently captures, transfers, and converts light energy, demonstrating the evolutionary diversity of photosynthesis and the ultimate pursuit of light.

Preprint -
Excited to present WHOLISTIC, which extends the concept of whole-brain functional imaging to the entire body. Pioneering work by incredibly talented Virginia Ruetten @vmsruetten.bsky.social, this platform reveals whole-organism cellular dynamics in vivo.

At the Reform UK conference, Dr Aseem Malhotra made a number of claims about Covid vaccines, some of which were misleading or simply not backed by any credible evidence.

We’ve fact checked a few of his claims 👇
