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.

Crocodiles killed by liver cirrhosis

on
As many as 26 endangered crocodiles have been found dead over the last three days in northern India and experts attribute the rare mass deaths to cirrhosis of the liver, authorities said on Friday. The reptiles died in the waters of the Chambal river, which runs along the borders of the northern state of Uttar Pradesh and the central state of Madhya Pradesh, baffling experts as it is considered their natural habitat. "Autopsies confirm liver cirrhosis as the cause of death," D.N.S. Suman, Uttar Pradesh's top wildlife official, told Reuters from Etawah town on the banks of the Chambal where experts have camped to investigate the deaths. Poisoning was not suspected as fish in the river had not died, Suman said, adding that scientists would test the water for the presence of any liver-damaging toxins. Cirrhosis is marked by the loss of liver tissue, leading to the loss of function of the vital organ, a report from Reuters.
