Rapid genetic evolution linked to lighter skin pigmentation in a southern African population

Posted by in categories: evolution, genetics

Populations of indigenous people in southern Africa carry a gene that causes lighter skin, and scientists have now identified the rapid evolution of this gene in recent human history.

The gene that causes lighter pigmentation, SLC24A5, was introduced from eastern African to southern African populations just 2,000 years ago. Strong positive selection caused this gene to rise in frequency among some KhoeSan populations.

UC Davis anthropologist Brenna Henn and colleagues have shown that a gene for lighter skin spread rapidly among people in southern Africa in the last 2,000 years.

Researchers say coffee may combat two devastating brain diseases

Posted by in categories: biotech/medical, neuroscience

The past few years have brought lots of good news for anyone who considers coffee a vice. Scientists have discovered that various compounds in coffee can help fight a number of diseases including Alzheimer’s, and now a new study is putting even more weight behind the notion that coffee is very good for you.

The work, which was published in Proceedings of the National Academy of Sciences, suggests that not only does coffee battle Parkinson’s but also another incurable brain disease called Lewy body dementia. Conducted by scientists at Rutgers, the study points to the combined effects of caffeine and a fatty acid present in coffee called EHT as potentially playing key roles in disease fighting.
