New technique reveals genes underlying human evolution

E-Mail
One of the best ways to study human evolution is by comparing us with nonhuman species that, evolutionarily speaking, are closely related to us. That closeness can help scientists narrow down precisely what makes us human, but that scope is so narrow it can also be extremely hard to define. To address this complication, researchers from Stanford University have developed a new technique for comparing genetic differences.
Through two separate sets of experiments with this technique, the researchers discovered new genetic differences between humans and chimpanzees. They found a significant disparity in the expression of the gene SSTR2 - which modulates the activity of neurons in the cerebral cortex and has been linked, in humans, to certain neuropsychiatric diseases such as Alzheimer s dementia and schizophrenia - and the gene EVC2, which is related to facial shape. The results were published March 17 in ....

Recruiting and selecting the proper sailors for specific tasks in the U.S. Navy has proven tricky, with costs rising yearly as the military seeks to match sailors with appropriate specialties. A University of Houston professor of psychology and a team of collaborators is out to save the military money and streamline the process by developing a new personnel selection process, the Manpower and Personnel Assessment Battery (MPAB). ....

A large study of people in 28 countries found men aged 50 and over had a 60 per cent greater risk of death than women, partly explained by heavier rates of smoking and heart disease in men, although the
gap varied across countries. The new research was published in CMAJ (Canadian Medical Association Journal).
“Many studies have examined the potential impact of
social, behavioural and biological factors on sex diff erences in mortality, but few have been able to investigate potential variation across countries,” writes Dr Yu-Tzu Wu, ....

Science FAIL! A perilous story of why it's good to do

Download 35.28 MB
When accomplished young German neuroscientist Ben de Haas opened his email back in June last year - in the thick of home-schooling three children and running a busy research team in a pandemic - he couldn t have imagined what was about to happen.
The email was from PhD student Susanne Stoll at his former university in London.
Something was up. Something big.
A candid personal and scientific odyssey challenging the stigma of failure in science.
On stuffing up, why it s so vital to scientific progress itself, and.why retraction isn t necessarily a dirty word.
