Scientific American: Prehistoric viruses and the function of the brain

You might be forgiven for having never heard of the NotPetya cyberattack. It didn’t clear out your bank account, or share your social media passwords, or influence an election. But it was one of the most costly and damaging cyberattacks in history, for what it did target: shipping through ports. By the time the engineers […]

This age group draws particular attention because screen immersion […]

Science Daily: Dopamine’s yin-yang personality: It’s an upper and a downer

Dopamine has a reputation as the key player in the brain’s reward circuits, making us seek out pleasurable experiences, but growing evidence points to a multipronged role for the neurotransmitter. In particular, dopamine may also reinforce avoidance of painful experiences. Researchers have now mapped dopamine neurons in the brain with fiber photometry and discovered two […]

Inverse: The brain takes forever to wake up and there’s nothing we can do about it

The night is dark and full of terrors, but for most of us the true terror begins each morning when the alarm clock goes off. This year, scientists at the University of California Berkeley discovered a key reason why so many of us spend precious mornings groping for reality in a sleep-induced fog. “Sleep inertia” […]

Science Daily: Being yelled at: Our brain on alert in a flash

What happens within the brain when it perceives a threatening signal, such as an aggressive voice? Researchers have studied brain activity during the processing of various emotional voices. They discovered that we notice a voice much faster when it is considered threatening than when it is perceived as normal or happy. Our attention is more […]

Reuters: More evidence fruits and greens can be good for the brain

Middle-aged men who eat lots of fruits and vegetables may be lowering their odds of cognitive problems as they get on in years, compared to peers who don’t consume these foods very often, a U.S. study suggests. Researchers followed almost 28,000 men for two decades starting when they were 51 years old, on average. (December […]

News-Medical: Yale researchers predict how people’s eyes move when viewing natural scenes

Using precise brain measurements, Yale researchers predicted how people’s eyes move when viewing natural scenes, an advance in understanding the human visual system that can improve a host of artificial intelligence efforts, such as the development of driverless cars, said the researchers. “We are visual beings and knowing how the brain rapidly computes where to […]
