BREAKTHROUGH:
Researchers just discovered that a simple two-step treatment helped mice regenerate complex digit structures after amputation.
Scientists first applied FGF2 (Fibroblast Growth Factor 2) to trigger a regenerative structure called a blastema, then used BMP2 (Bone Morphogenetic Protein 2) to guide the growth of new bone, tendons, ligaments and joint tissues.
The results suggest that mammals may still possess dormant regenerative abilities, and that regeneration could be activated by the right biological signals rather than requiring entirely new cells.
For most of human history, lost tissue was considered gone forever. This research hints at a future where medicine move beyond repairing damage and begin restoring what was lost 👀
🚨 SCIENTISTS JUST CREATED A WAY TO KILL ANTIBIOTIC-RESISTANT BACTERIA USING NOTHING BUT LIGHT.
Researchers have developed graphene quantum dots that destroy over 99.9% of antibiotic-resistant S. aureus and E. coli when hit with low-intensity blue light without using any antibiotics at all.
The dots work by generating reactive oxygen species that rip apart bacterial cells.
After chemically modifying them, the team made the dots over 20 times more efficient, allowing them to work at very low concentrations. Because they’re made from graphene instead of toxic heavy metals, they’re also much safer for medical use.
Why this matters:
• Antibiotic resistance is one of the fastest-growing threats to global health
• This offers a completely different weapon light instead of drugs
• The dots could be used in wound dressings, creams, gels, and coatings for implants and catheters
• Graphene is cheap, stable, and biocompatible
The deeper implication:
We’re running out of effective antibiotics, and bacteria are evolving faster than we can develop new drugs. This approach flips the script: instead of fighting bacteria with chemicals they can eventually resist, we use light to trigger a physical attack they can’t easily adapt to.
If this scales, it could become a powerful new tool in the fight against superbugs especially for wound infections and medical devices, where resistant bacteria are hardest to treat.
Sometimes the solution isn’t a better drug. It’s a better way to attack.
Would you trust a light-activated treatment over traditional antibiotics if it worked this well?

Can we use machine learning to predict longevity drugs? 💊
In our updated preprint led by @AlekseyVBelikov we trained ML models on compounds in the DrugAge database that extend lifespan in mice. Features associated with longevity drugs included receptors for neurotransmitters, metabolic hormones and sex hormones.
We then used our top-performing models to screen DrugBank for new potential longevity drugs. Identified clusters included compounds targeting IGF1 and insulin receptors, beta adrenergic receptors, carbonic anhydrases, dopamine and serotonin receptors.
In collaboration with @scrippsresearch we tested 22 predicted compounds in C. elegans and found that 6 of them extended lifespan: dihydroergotamine, mianserin, bromocriptine, voxtalisib, bms-754807 and solifenacine.
With our collaborators @UniKent we also created a public web server with our top models.
Feedback welcome.
