A research team from Los Alamos National Laboratory and Purdue University have developed bio-inks for biosensors that could help localize critical regions in tissues and organs during surgical $operations.

“The ink used in the biosensors is biocompatible and provides a user-friendly design with excellent workable time frames of more than one day,” said Kwan-Soo Lee, of Los Alamos’ Chemical Diagnostics and Engineering group.

The new biosensors allow for simultaneous recording and imaging of tissues and organs during surg...

Findings lay the groundwork for new stroke treatments, prevention strategies. New findings from Cleveland Clinic researchers show for the first time that the gut microbiome impacts stroke severity and functional impairment following stroke. The results, published in Cell Host & Microbe, lay the groundwork for potential new interventions to help treat or prevent stroke.

The research was led by Weifei Zhu, Ph.D., and Stanley Hazen, M.D., Ph.D., of Cleveland Clinic’s Lerner Research Institute. The study builds on more than a decade of research spearheaded by Dr...

Several different causes of ageing have been discovered, but the question remains whether there are common underlying mechanisms that determine ageing and lifespan. Researchers from the Max Planck Institute for Biology of Ageing and the CECAD Cluster of Excellence in Ageing research at the University Cologne have now come across folate metabolism in their search for such basic mechanisms. Its regulation underlies many known ageing signalling pathways and leads to longevity. This may provide a new possibility to broadly improve human health during ageing.

In recent decades, several cellular signalling pathways have been discovered that regulate the lifespan of an organism and are thus of enormous importance for a...

A new therapy prompts immune defense cells to swallow misshapen proteins, amyloid beta plaques and tau tangles, whose buildup is known to kill nearby brain cells as part of Alzheimer’s disease, a new study shows.

Led by researchers at NYU Grossman School of Medicine, the investigation showed that elderly monkeys had up to 59 percent fewer plaque deposits in their brains after treatment with CpG oligodeoxynucleotides (CpG ODN), compared with untreated animals. These amyloid beta plaques are protein fragments that clump together and clog the junctions between nerve cells (neurons).

Brains of treated animals also had a drop in levels of toxic tau...
