Phys.org / 'Plastic-eating' fusion enzyme improves polyester textile recycling
In a new study, scientists from the universities of Portsmouth and Manchester report that a specially engineered enzyme can significantly speed up the breakdown of PET—the plastic used in water bottles, food packaging and ...
Medical Xpress / Stability of brain's internal compass may help explain how memories last
A new discovery by McGill researchers sheds light on how we retain memories over time, even though brain activity is constantly changing. Published in Nature, the preclinical study found the brain's internal compass remains ...
Medical Xpress / The Alzheimer's gut-brain link: How butyrate could curb amyloid-β buildup and inflammation
Alzheimer's disease (AD) is a neurodegenerative disease that causes progressive memory loss and a significant decline in mental functions. Past studies have shown that people with AD exhibit a buildup of a protein called ...

Phys.org / Engineered nanoparticles show enhanced intrinsic luminescence for biomedical imaging and cancer treatment
The Nanomedicine and Nanotoxicology Group (GNano) at the University of São Paulo's São Carlos Institute of Physics (IFSC-USP) in Brazil has discovered a way to transform hydroxyapatite, a bioceramic material, into a nanoparticle ...
Phys.org / ISS study identifies thresholds for muscle atrophy and fiber changes in reduced gravity
It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient ...
Medical Xpress / It's not just vaccines—parents are refusing other routine preventive care for newborns
One day at an Idaho hospital, half the newborns Dr. Tom Patterson saw didn't get the vitamin K shots that have been given to babies for decades to prevent potentially deadly bleeding. On another recent day, more than a quarter ...
