UMass Amherst engineers have built an artificial neuron powered by bacterial protein nanowires that functions like a real one, but at extremely low voltage. This allows for seamless communication with biological cells and drastically improved energy efficiency. The discovery could lead to bio-inspired computers and wearable electronics that no longer need power-hungry amplifiers. Future applications may include sensors powered by sweat or devices that harvest electricity from thin air.

A team at Massachusetts General Hospital uncovered that an immune defense protein, Resistin-like molecule gamma, attacks heart cells after a heart attack—literally punching holes in them. This discovery explains why dangerous, fast heart rhythms can strike after an infarction. By removing this molecule in mice, the researchers reduced deadly arrhythmias twelvefold, suggesting that targeting immune-driven damage could open a new path to preventing sudden cardiac death.

Scientists at Mass General Brigham have created HPV-DeepSeek, a blood test that can detect HPV-linked head and neck cancers nearly a decade before diagnosis. By finding viral DNA in the bloodstream, the test achieved 99% sensitivity and specificity. This breakthrough could lead to earlier, less invasive treatments and significantly improve survival. A large NIH trial is underway to confirm the results.

Overdose deaths from fentanyl mixed with stimulants have skyrocketed among seniors, increasing 9,000% in just eight years. Once thought to affect mainly the young, the opioid epidemic’s fourth wave now engulfs older adults too. Cocaine and methamphetamine are the leading culprits, and experts warn that multi-drug use makes these overdoses especially lethal. Doctors are urged to educate patients and caregivers on prevention and safer pain management.
