Per-and polyfluoroalkyl substances (PFAS), manufactured chemicals used in products such as food packaging and cosmetics, can lead to reproductive problems, increased cancer risk and other health issues. A growing body of research has also linked the chemicals to lower bone mineral density, which can lead to osteoporosis and other bone diseases. But most of those studies have focused on older, non-Hispanic white participants and only collected data at a single point in time.

Now, researchers from the Keck School of Medicine of USC have replicated those results in a longitudinal study of two groups of young participants, primarily Hispanics, a group that faces a heightened risk of bone disease in adulthood.

“This is a population completely understudied in this area of research, despite having an increased risk for bone disease and osteoporosis,” said Vaia Lida Chatzi, MD, Ph.D., a professor of population and public health sciences at the Keck School of Medicine and the study’s senior author.

In 2006, Paul Rothemund transformed the field of DNA nanotechnology when he unveiled an innovative approach for making shapes and patterns from genetic material.

Consciousness isn’t just a problem for philosophers. On this episode of Dispatches, Kmele sat down with scientists, a mathematician, a spiritual leader, and an entrepreneur, all trying to get to the heart of “the feeling of life itself.”

An enormous dark hole has opened up in the sun’s surface and is spewing powerful streams of unusually fast radiation, known as solar wind, right at Earth. The size and orientation of the temporary gap, which is wider than 60 Earths, is unprecedented at this stage of the solar cycle, scientists say.

The giant dark patch on the sun, known as a coronal hole, took shape near the sun’s equator on Dec. 2 and reached its maximum width of around 497,000 miles (800,000 kilometers) within 24 hours, Spaceweather.com reported. Since Dec. 4, the solar void has been pointing directly at Earth.

Experts initially predicted this most recent hole could spark a moderate (G2) geomagnetic storm, which could trigger radio blackouts and strong auroral displays for the next few days. However, the solar wind has been less intense than expected, so the resulting storm has only been weak (G1) so far, according to Spaceweather.com. But auroras are still possible at high latitudes.

On the internet, nothing is safe — not even your DNA, apparently.

That’s the dystopian lesson from the commercial genetic testing company 23andMe, which disclosed on Friday in a regulatory filing that hackers managed to access information on about 14,000 users or 0.1 percent of its customer user base.

But the problem goes beyond this relatively small number of people. Because the website allows users to share DNA information with other users in order to find relatives, the true number impacted is orders of magnitude larger — with about 6.9 million customers having their personal information compromised, according to TechCrunch. Big yikes on that figure, because it affects something like half of the 14 million users at 23andMe.

Researchers find the brain structure is crucial for informing us where are bodies are and what they’re doing.
