Fenchol, a natural compound abundant in some plants including basil, can help protect the brain against Alzheimer’s disease pathology, a preclinical study led by University of South Florida Health (USF Health) researchers suggests.

The new study published Oct...

People with the same lifespan do not necessarily have the same quality of life. As we live longer, extending quality of life – “healthspan” – is gaining importance. Scientists at the Okinawa Institute of Science and Technology Graduate University (OIST) have discovered a gene linked with healthy ageing in the roundworm C. elegans, shedding light on the genetics of healthspan.

The team has identified a gene called elpc-2 in C. elegans that plays an important role in maintaining healthspan as the worm ages. This gene is conserved in humans – and worms with defects in this gene showed impaired movement as they aged...

For the 1st time, a causal link between RNA splicing and aging has been revealed. The finding sheds light on the biological role of splicing in lifespan and suggests that manipulating specific splicing factors in humans might help promote healthy aging...
