The company has genetic data of 15 million people, which could be shared with a future buyer. Here’s how to delete it. Plus, an experimental coating could make golf balls roll more reliably on greens with different conditions.

After 23andMe Bankruptcy, Customers Urged To Delete Their Data

If you’re one of roughly 15 million people who used 23andMe to unlock information from their DNA, consumer advocates have a message for you: Delete your data. On Sunday, the company, which has customers send saliva samples for DNA analysis, filed for bankruptcy. While many customers submitted their saliva for the purpose of ancestral analysis, 85% of customers also consent to their data used for genetic disease research.

As the company searches for a buyer, consumer advocates, including California Attorney General Rob Bonta, have urged customers to delete their data from 23andMe’s website. 23andMe and other genetic testing companies are not subject to HIPAA, meaning health and medical records kept by 23andMe could be shared with a future buyer.

Producer Kathleen Davis joins Host Flora Lichtman to discuss this and other top science stories of the week.

Chemists Make A Coating That Can Slow A Golf Ball’s Roll

With spring here, the days are getting warmer and longer, meaning conditions are perfect for a trip to the golf course. And while golf is certainly a game of physics—force, angles, parabolas—this week researchers presented work showing that chemistry could play an important role on the golf course as well. Speaking at the meeting of the American Chemical Society in San Diego, researchers described a high performance coating that could be incorporated into the polyurethane shell of a golf ball.

The hydrophilic (water-loving) coating would make tiny bits of water stick to the surface of the golf ball and sheet off, modifying the way the ball interacts with the grass of the green. That interaction, says Tom Kennedy, owner of Chemical Innovative Solutions Inc., would lead to the ball rolling more slowly and reliably, especially on “fast,” closely-cut greens in dry and windy conditions.

Kennedy joins Host Ira Flatow to discuss the technology, and how hydrophilic coatings could find a home in other applications, including solar cells.
