Are you an empathetic person?

After a 60-minute walk in nature, activity in brain regions involved in stress processing decreases, a new study concludes.

They conclude that psychological factors, such as feeling unhappy, lonely or desperate, add up to 1.65 years to biological age, more than smoking.

These are electrodes that are inserted into the brain and mimic what the hippocampus does naturally. It works better in people with poor memory.

This is what made us so different from Neanderthals. A subtle change in a single gene gave us the advantage.

A recent study shatters the theory of evolution. The work bucks the widely held belief that modern humans experienced an evolutionary decline in brain size. According to experts, the size of the human brain has not changed in probably 300,000 years.
