Check out this wonderful piece by @vcallier.bsky.social on how parts of the human immune system can be traced back to the conflict between bacteria and phages!

Thank you so much, @kranzuschlab.bsky.social!!! And thank you for tagging the fantastic researchers working in this exciting, rapidly developing field.

Thank you to @vcallier.bsky.social and Quanta Magazine for highlighting our lab along with the incredible research from @soreklab.bsky.social @audeber.bsky.social @aaronwhiteley.bsky.social @benmorehouse.bsky.social @teralevin.bsky.social @algao.bsky.social Eugene Koonin, L. Aravind and others!

Over two billion years, a fierce battle has raged between bacteria and the viruses that infect them. The resulting evolution has shaped the way our bodies fight disease today. @vcallier.bsky.social reports: www.quantamagazine.org/the-ancient-...

Thank you, Noah!!

Drosophila and anti-parasitoid defense gained through horizontal gene transfer from phages make a cameo at the end of this fun article by @vcallier.bsky.social...

Immune conflict in placenta affects male fetal development The immune-conflict between dam and fetus could help explain sex differences in neurodevelopmental conditions.

“Understanding autism from a variety of perspectives, whether it’s neurological, immunological, or even ‘placentological’—I think those are all important pieces of the puzzle,” says @cheadlelab.bsky.social of @cshlnews.bsky.social.

Neurons modulate sensitivity via electron transport chain Some nociceptors can survive a lifetime’s worth of exposure to noxious stimuli by reducing their mitochondria’s production of reactive oxygen species.

How is it that some nociceptors—the sensory neurons that detect heat, chemical irritants and toxins—can withstand a lifespan’s worth of exposure to noxious stimuli, whereas others die? New findings reveal how they do it.

New findings solve “developmental biology’s most complicated problem”: how each olfactory neuron in the ant expresses exactly one out of hundreds of olfactory receptors.

Ant olfactory neurons reveal new gene regulation mechanism The mechanism enables each olfactory neuron in the ant to express exactly one out of hundreds of olfactory receptors.

Don't miss this piece in @thetransmitter.bsky.social by @vcallier.bsky.social on @danielkronauer.bsky.social's latest work! His lab discovered that a protective screen of spurious transcriptional activity enables each olfactory neuron to express exactly one out of hundreds of olfactory receptors.

Covering Null Results: How to Turn “Nothing” into News - The Open Notebook Null results—those that contradict a study’s original hypothesis or fail to find a cause-and-effect link between variables—can be easy to dismiss as non-news but may lead to valuable stories that show...

Covering null results can help reporters contribute to a more accurate view of science and the world, writes @bwfund.bsky.social early-career fellow Lucila Pinto in TON’s latest, with insights from @vcallier.bsky.social, @ldattaro.bsky.social, @claricecudi.bsky.social and others. 🧪

Mitochondria set ‘ancient’ metabolic thermostat for sleep in flies, separate from circadian rhythms During waking hours, a specialized set of sleep neurons in the fly brain accumulates reactive oxygen species, which eventually trigger sleep to clean up and repair the damage they do.

Sleep might be an “inescapable consequence” of aerobic metabolism, new findings in fruit flies suggest.

How Metabolism Can Shape Cells’ Destinies | Quanta Magazine A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life.

Gender and retention patterns among U.S. faculty Women faculty are more likely to leave their jobs than men, most often due to workplace climate, rather than work-life balance.

Women leave academia at higher rates than men at every career stage, and attrition is especially high among three groups: tenured faculty, women in non-STEM fields, and women employed at less prestigious institutions, a #ScienceAdvances analysis finds.

The illnesses & deaths in Panzi region, DRC, were caused by a combo of regular respiratory bugs + malaria, in people weakened by severe malnutrition. Not a new disease but definitely a local tragedy. www.who.int/emergencies/...

Living is about taking risks and not knowing the outcome. David Spiegelhalter explains why it’s important to accept and embrace this—if necessary, we might even take a cue from our pet dog:

‘It felt very icky’: This scientist’s name was used to write fake peer reviews Elsevier retracts dozens of journal articles that were published based on “fictitious” reviews

Earlier this year, I received news that fake peer reviews were allegedly being submitted impersonating me and approximately six others

I shared my story with Science to, hopefully, reduce the chance of this kind of breach happening again

‘Systematic reviews’ that aim to extract broad conclusions from many studies are in peril Fake papers are “poisoning the well” for these gold-standard syntheses, researchers say

A growing problem --- fake papers polluting systematic reviews. And interesting point that the gold-standard protocols that Cochrane is developing to weed out untrustworthy studies, are too much of an effort for systematic-review authors looking at 100s of papers. www.science.org/content/arti...

Digestive contents and food webs record the advent of dinosaur supremacy - Nature Integrated analyses of bromalites provide robust pictures of past food webs, explaining early dinosaur evolution and the emergence of larger dinosaur faunas with new feeding patterns.

You’re in luck Sabrina! A new paper on dinosaur faeces just “dropped” today! By the wonderful @perahlberg.bsky.social and colleagues

How cool! Congrats!!
