Prenatal pesticide exposure linked to changes in teen’s brain activity

Organophosphates are among the most commonly used classes of pesticides in the United States, despite mounting evidence linking prenatal exposure to the chemicals to poorer cognition and behavior problems in children. A new study led by University of California, Berkeley, researchers is one of the first to use advanced brain imaging to reveal how exposure to these chemicals in the womb changes brain activity.

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.

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.

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.

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.

Historically redlined communities face higher asthma rates

The long-term effects of redlining, which for decades was used to justify discriminatory mortgage lending practices, may be impacting the current health of affected communities, suggests new research from the University of California, Berkeley, and the University of California, San Francisco.

Anxiety ‘epidemic’ brewing on college campuses, researchers find

The number of 18- to 26-year-old students who report suffering from anxiety disorder has doubled since 2008, perhaps as a result of rising financial stress and increased time spent on digital devices, according to preliminary findings released Thursday by a team of UC Berkeley researchers.

Insulin Insights

Many aspects of insulin signaling remain unclear, particularly its long-term effects on cells, and there are currently no effective cures for the hundreds of millions of people around the world living with diabetes. Now, Professor Anders Näär and collaborators from Harvard Medical School (HMS) have made key new insights into the molecular behavior of insulin.

Discovery could help improve cystic fibrosis treatment

Researchers exploring the effects of a long-standing treatment for cystic fibrosis have discovered a potential new target for drugs to treat the disease, which has no cure and typically cuts decades off the lives of patients.

Whopping big viruses prey on human gut bacteria

Viruses plague bacteria just as viruses like influenza plague humans. Some of the largest of these so-called bacteriophages have now been found in the human gut, where they periodically devastate bacteria just as seasonal outbreaks of flu lay humans low, according to a new study led by UC Berkeley scientists.

Recorded sounds that plagued U.S. diplomats in Cuba just crickets hard at work

UC Berkeley integrative biology Ph.D. student Alexander Stubbs and colleague determined that a mysterious noise reported by U.S. diplomats stationed in Cuba plagued by resulting hearing loss and other medical symptoms was not from sonic attacks as feared, but was produced by the Indies short-tailed cricket (Anurogryllus celerinictus).

Drug sponge could minimize side effects of cancer treatment

With the help of sponges inserted in the bloodstream to absorb excess drugs, doctors are hoping to prevent the dangerous side effects of toxic chemotherapy agents or even deliver higher doses to knock back tumors, like liver cancer, that don’t respond to more benign treatments.
