The view of the world through any primate’s eyes is funnelled from the retina into the visual cortex, the various layers of which do the initial processing of incoming information. At first, it’s little more than pixels of dark or bright colours, but within 100 milliseconds the information zaps through a network of brain areas for further processing to generate a consciously recognized, 3D landscape with numerous objects moving around in it.

Being in space can have weird and sometimes harmful effects on the human body, and we’ll have to work through those issues if we’re to make it out to Mars and beyond, and stay healthy.

But it looks like we have finally found one feature of the human body that’s untroubled by microgravity — and it’s a part of our all-important immune system.

Based on a study of blood samples from International Space Station (ISS) crew members, a few months in space don’t affect B-cell immunity — the number of white blood cells in our bodies ready to fight off infection by producing antibodies.

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 skin 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.

The team combines 1,200 scientists from 52 countries in disciplines ranging from geology and microbiology to chemistry and physics. A year before the conclusion of their 10-year study, they will present an amalgamation of findings to date before the American Geophysical Union’s annual meeting opens this week.

Global team of scientists find ecosystem below earth that is twice the size of world’s oceans.

The NASA explorer’s initial discoveries might provide some insight into the early Solar System.

“The prospect of intervening in a profound way in human aging is still not seen as credible by the vast majority of thoughtful people around the world,”

Here’s the Inside Scoop from an Icon in the Longevity Field.

We thought we knew everything about carbon. We were wrong.

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.
