Scientists identify new fuel-delivery route for cells

Scientists at Washington University School of Medicine in St. Louis have identified a previously unknown route for cellular fuel delivery, a finding that could shed light on the process of aging and the chronic diseases that ...

Anti-aging molecule NAD+ gets a boost from blocking an enzyme

Nicotinamide adenine dinucleotide (NAD+) is a major player in nutrition today. Studies have shown that NAD+ concentrations decrease during aging and that recovering the body's levels of NAD+ can prolong both health span and ...

Imaging method evaluates cell functional changes and wound healing

Kyle Quinn, assistant professor of biomedical engineering at the University of Arkansas, has published a review highlighting recent advances in autofluorescence imaging and discussing its role in evaluating cell metabolism.

New insight into the molecular weapons of the plant microbiome

Like all organisms, plants are associated with bacterial communities in which helpful and harmful bacteria compete for dominance. Among the weaponry of these warring bacteria are molecular syringes that some bacteria can ...

Chemists slide a splitting catalyst over DNA for the first time

Chemists from Nijmegen, The Netherlands, have developed a catalyst that binds to DNA, slides over it and splits the molecule in particular places. The researchers were able to do this by synthetically modifying a natural ...

Stable Thanks to Dynamics - DNA Component Resists UV Radiation

(PhysOrg.com) -- Complex computer simulations have, for the first time, allowed scientists to examine in detail the processes that help to ensure the stability of DNA when exposed to UV light. The findings, achieved primarily ...
