Testosterone makes men less likely to question their impulses

Fri, 28/04/2017 - 7:45pm
Testosterone makes men less likely to realize when they're wrong, a new study shows. The researchers found that men given doses of testosterone performed more poorly on a test designed to measure cognitive reflection than a group given a placebo.

Unravelling the mystery of DNA attacks in cells' powerhouse could pave way for new cancer treatments

Fri, 28/04/2017 - 6:55pm
A five-year study has found the mechanism responsible for repairing damage to mitochondrial DNA. This discovery could pave the way for new treatments for cancer and neurodegenerative diseases, say the researchers. This research may also have important implications for clinical advances in so called ‘three-parent baby’ mitochondrial donation.

Counting the cuts in Mohs surgery: A way to improve care and reduce costs

Fri, 28/04/2017 - 5:15pm
In an analysis of Medicare billing data submitted by more than 2,300 United States physicians, researchers have calculated the average number of surgical slices, or cuts, made during Mohs micrographic surgery (MMS), a procedure that progressively removes thin layers of cancerous skin tissue in a way that minimizes damage to healthy skin and the risks of leaving cancerous tissue behind.

Plague bacteria take refuge in amoebae

Fri, 28/04/2017 - 5:15pm
Yersinia pestis, the bacterium that causes bubonic plague, can survive within the ubiquitous soil protozoan, the amoeba, by producing proteins that protect against the latter microbe's digestion, report scientists.

Modern metabolic science yields better way to calculate indoor carbon dioxide

Fri, 28/04/2017 - 5:14pm
The air we breathe out can help us improve the quality of the air we breathe in. But to do so, one needs a reliable way to calculate the concentration of carbon dioxide we produce indoors. Researchers have developed a new computation method that uses well-established concepts from the study of human metabolism and exercise physiology to significantly improve how this important data is derived.
