Small Protein, Big Impact: Microprotein Discovery Offers Hope for Obesity and Aging

on
Researchers have uncovered a tiny but powerful protein that helps keep our cells’ energy factories humming – a discovery that could spark new approaches to tackling obesity and age-related decline. Scientists at the Salk Institute in La Jolla found that a  “microprotein”  in mouse fat cells plays a critical role in maintaining healthy  mitochondria , the structures that generate energy in our cells. By preserving mitochondrial function, this diminutive protein helps cells burn fuel efficiently, which in turn could influence body weight and the aging process. The findings shine light on how molecular biology connects to everyday health, opening the door to  science-backed strategies for better metabolism and longevity.

Use of cadavers in NASA project, an official report

on
An Ohio State University Medical Center project contracted by NASA used cadavers to create technology for the Orion shuttle, space agency officials say. Dustin Gohmert, who designs seats for the National Aeronautics and Space Administration, said three human bodies were used to develop special suits and landing systems for the NASA spacecraft, the Houston Chronicle reported Saturday. "The testing with postmortem human subjects and mannequins is helping NASA to better define the human injury potential for the landing (forces) that we anticipate with Orion," Gohmert said of last year's testing at the Ohio site.

David Steitz, a spokesman for the NASA medical division, said the space agency follows current ethical standards whenever utilizing donated cadavers for research purposes. "It's a socially awkward topic," Steitz told the Chronicle. "The bodies are all carefully handled through all of the tests. We follow ethical medical procedures with these bodies that have been donated for science." Source: UPI.com
