Very happy to start 2026 by sharing our new manuscript in Nature Metabolism.✨ By studying the constitutive adipocytes in the bone marrow, we identified a brain-mediated pathway that bypasses the SNS to evoke massive fat loss. 🧠🦴

A new study reveals how the brain triggers the breakdown of stable fat cells that normally resist diet and exercise. This discovery provides evidence for how severe wasting diseases cause dangerous weight loss in vulnerable patients. https://t.co/wLsmrSWFQB
Specific Brain Signals Rapidly Eliminate Body Fat in Mice
Sustained injection of leptin into the brain was shown to unlock stable adipocytes, leading to complete loss of body fat.
Researchers at WashU Medicine have identified a potent pathway that begins in the brain and leads to loss of all body fat without reducing food intake.
In mice, sustained injection of leptin, a hormone, into the brain was able to unlock the stable adipocytes by putting the body into a state of low glucose and insulin. This reduced the inhibitors of fat breakdown, causing complete loss of body fat within days, even though the mice were still eating normally.

Big anti aging news
Scientists Identify Core "Aging Genes" Shared Across Species. Silencing Them Extends Lifespan
Researchers publishing in Aging Cell have pinpointed a set of core genes that drive aging across multiple species, from humans to worms.
By analyzing 25 large gene expression datasets and testing the results in C. elegans, they found 6 key genes whose suppression extended lifespan by up to 15%.
These genes regulate immune activity, tissue maintenance, and DNA stability, and many are already linked to age related diseases like Alzheimer’s and macular degeneration.
The findings reveal universal aging mechanisms and new targets for anti aging therapies.
@DrAhmedAlSaedi Thank you for your leadership on the ISBM ECI Committee over the past two years! The momentum and enthusiasm in our early careers is so exciting to see. The future is bright because of stars like you. 🌟
🎬And that's a wrap! Thanks to everyone that made #ISBM2024 a success. We hope you met some new buddies and left with new tools, ideas, and inspiration. We look forward to staying in touch until we see you again in London at ISBM 2026!
Followed up by a very neat live demo for setting up an AI-assisted image registration pipeline! Lots to learn for the biologists - but very cool to see an expert go through the steps in real time.
