New Brain Study Shows How Obeying Orders Can Dull Our Empathy War atrocities are sometimes committed by ‘normal’ people obeying orders. Researchers from the Netherlands Institute for Neuroscience measured brain activity while participants inflicted pain and found that obeying orders reduced empathy and guilt related brain activity for the inflicted […]

ANU, Author provided Prehistoric axes and beads found in caves on a remote Indonesian island suggest this was a crucial staging post for seafaring people who lived in this region as the last ice age was coming to an end.

Robert Collins/Unsplash Archaeological records— and the modern-day antics of our primate relatives—make it clear that monkeying around goes way back. Less certain, however, are the developmental and evolutionary advantages that underlie our instinct […]

ANIMATION Our brains have an upper limit on how much they can process at once due to a constant but limited energy supply, according to a new UCL study using a brain imaging method that measures cellular metabolism. The study, published in the Journal of Neuroscience, found that paying attention can […]

Study shows how traumatic experiences can leave their mark on a person’s eyes. New research by Welsh academics shows that a patient’s pupils can reveal if they have suffered a traumatic experience in the past. Post-traumatic stress disorder can occur when a person has experienced a traumatic event such as […]

Chiquihuite Cave in Mexico. Devlin A. Gandy, Author provided Humans lived in what is now Mexico up to 33,000 years ago and may have settled the Americas by travelling along the Pacific coast, according to two studies by myself and colleagues published today. It has been commonly believed that the first […]

It’s not just heavy drinking that’s a problem — even consuming alcohol within weekly low-risk drinking guidelines can result in hospitalization and death, according to a new study published in the Journal of Studies on Alcohol and Drugs. Moderate drinkers “are not insulated from harm,” write researchers led by Adam Sherk, […]
