Here’s how early humans evaded immunodeficiency viruses

For hundreds of thousands of years, monkeys and apes have been plagued by simian immunodeficiency virus (SIV), which still devastates primate groups in Africa. Luckily, as humans evolved from these early primates, we picked up a mutation that made us immune from SIV — at least until the early 20th century, when the virus evolved to get around our defenses, giving rise to human immunodeficiency virus (HIV) and an AIDS pandemic that today affects an estimated 38 million people worldwide. University of California, Berkeley, researchers have now discovered how that long-ago human mutation interfered with SIV infection, a finding that could provide clues for the development of new therapies to thwart HIV and similar viral infections.

A map of the brain can tell what you’re reading about

Too busy or lazy to read Melville’s Moby Dick or Tolstoy’s Anna Karenina? That’s OK. Whether you read the classics, or listen to them instead, the same cognitive and emotional parts of the brain are likely to be stimulated. And now, there’s a map to prove it. UC Berkeley neuroscientists have created interactive maps that can predict where different categories of words activate the brain. Their latest map is focused on what happens in the brain when you read stories.

Wearable sensors detect what’s in your sweat

Needle pricks not your thing? A team of scientists at the University of California, Berkeley, is developing wearable skin sensors that can detect what’s in your sweat. They hope that one day, monitoring perspiration could bypass the need for more invasive procedures like blood draws, and provide real-time updates on health problems such as dehydration or fatigue.

Family influence key in spread of opioid use

Introducing an opioid painkiller into a home can double the chances someone else living in the home seeks out the addictive drugs on his or her own, according to a new paper from two UC Berkeley researchers.

Scientists map our underappreciated ‘little brain’

Scientists at UC Berkeley and Western University in Canada have used brain imaging to map the cerebellum, a formerly underappreciated neural region that contains the vast majority of the brain’s neurons, hence its Latin moniker “little brain.”

Berkeley Talks: Joel Moskowitz on the health risks of cell phone radiation

As of 2017, there were 273 million smartphones in use in the U.S and 5 billion subscriber connections worldwide, according to Joel Moskowitz, director of UC Berkeley’s Center for Family and Community Health at the School of Public Health. Moskowitz, who has conducted research on disease prevention programs and policies for more than 30 years, says that with the influx of smartphones has come hundreds of thousands of cell towers, which may pose health risks.

Bats’ brains sync when they socialize

The phrase “we’re on the same wavelength” may be more than just a friendly saying: A new study by University of California, Berkeley, researchers shows that bats’ brain activity is literally in sync when bats engage in social behaviors like grooming, fighting or sniffing each other.

Scientists chart course toward a new world of synthetic biology

Genetically engineered trees that provide fire-resistant lumber for homes. Modified organs that won’t be rejected. Synthetic microbes that monitor your gut to detect invading disease organisms and kill them before you get sick. These are just some of the exciting advances likely to emerge from the 20-year-old field of engineering biology, or synthetic biology, which is now mature enough to provide solutions to a range of societal problems, according to a new roadmap released today (June 19) by the Engineering Biology Research Consortium, a public-private partnership partially funded by the National Science Foundation and centered at the University of California, Berkeley.
