Study found that a common ingredient in sunscreen (zinc oxide) undergoes a chemical reaction when exposed to sunlight that can *increase* the risk of skin cancer! So, sunscreen can be dangerous when exposed to sunlight, and the longer it is exposed to sunlight the greater the potential damage to human cells!

The Hubble cannot look at the sun directly, so astronomers are going to point the Hubble at our moon and use it as a mirror to observe Venus moving across the sun's face. Imprinted on the small amount of light that passes through Venus's atmosphere then are the fingerprints of Venus's atmospheric makeup:

Using X-rays to detect breast cancer has drawbacks--some false positive and negative results and the exposure of women to low doses of radiation that carry some risk. Researchers are in clinical testing of a new device that uses light-induced sound to more effectively detect breast cancer without having any radiation exposure:

The Air Force, like the rest of the military and the CIA, isn't supposed to conduct "nonconsensual surveillance" on Americans domestically, according to an Apr. 23 instruction from the flying service. But should the drones taking off over American soil accidentally keep their cameras rolling and their sensors engaged, well … that's a different story.
The Air Force says that it "accidentally" can use its UAVs to track the movements of Americans and hold the data for 90 days, studying it to see if the people they "accidentally" spied upon are actually legitimate targets of domestic surveillance. If they really didn't want to spy on Americans on American soil they could just ignore that data, so it is quite an "accident" when they spent 90 days studying the data they "accidentally" obtained:

Alzeimer's disease currently has no cure, but a study found that a machine that sends continuous electrical impulses to the "memory" regions of the brain is able to increase brain activity--possibly helping people with mild Alzheimer's disease:

The FDA is considering a pill that can reduce HIV infection by 75%. The pill not only helps people with HIV fight off the disease, it can help healthy people avoid getting HIV. The pill appears to be safe and effective for prevention, but scientists said that it only works if it is taken every day:

The Nevada DMV gave Google the first license to test self-driving cars on public roads. The self-driving car's license plate will have a red background with an infinity symbol so that it can be easily recognized:

Verizon is rolling out a "text to 911" feature that will allow Verizon customers to contact 911 operators via text message to report an emergency. This is especially useful for the hearing and/or speech impaired and for those who are in situations where talking would be dangerous for them:
