One of a series of ova made in a spell of reproductive mitochondrial interest. The ovum about to ovulate has differentiated from the rest of the surrounding tissue and is getting ready to leave the ovary. Its mitochondria are...
Multiresistant bacteria Scientists around the world are working hard to win the battle against multi-resistant bacteria. A new publication from the BASP Centre, University of Copenhagen now presents how even sensitive bacteria often manage to survive antibiotic treatment as...

The saying goes that "your left hand doesn't know what your right hand is doing," but actually, your left hand is paying more attention than you'd think. Researchers at Tel-Aviv University found that when people practiced finger movements with...

James Webber took up barefoot running 12 years ago. He needed to find a new passion after deciding his planned career in computer-aided drafting wasn't a good...
PIWI-interacting RNAs, or piRNAs for short, are a class of 'small regulatory RNAs' -- tiny pieces of nucleic acid just 22-30 nucleotides in length. They may be small, but with their associated Argonaute proteins, piRNAs have the power to...

New research by scientists from the University of Bristol has revealed that domestic LED lights are much less attractive to nuisance insects such as biting midges than traditional filament lamps.
The team now highlights the urgent need...
Many pain-sensing nerves in the body are thought to respond to all types of 'painful events', but new research reveals that in fact most are specialized to respond to specific types such as heat, cold or mechanical pain
Many pain-sensing...

Four nucleotides, abbreviated A, C, G, and T, spell out DNA sequences that code for all of the proteins cells need. MIT researchers have now discovered another layer of control, mediated by transfer RNA, that helps cells to rapidly...
