Images of our faces exist in numerous important databases – driver’s license, passport, law enforcement, employment – all to accurately identify us. But can these images continue to identify us as we age?

The combination of prolonged hot spells with poor air quality greatly compounds the negative effects of each and can pose a major risk to human health, according to new research from the University of California, Irvine.

“The weather factors that drive heat waves also contribute to intensified surface ozone and air pollution episodes,” said UCI professor of Earth system science Michael J. Prather, co-author of the study, published this week in Proceedings of the National Academy of Sciences. “These extreme, multiday events tend to cluster and overlap, worsening the health impacts beyond the sum of their individual effects.”

A tailored preventive oral health intervention significantly improved the cleanliness of teeth and dentures among elderly home care clients. In addition, functional ability and cognitive function were strongly associated with better oral hygiene, according to a new study from the University of Eastern Finland. The study is part of a larger intervention study, NutOrMed, and the findings were published in the Age and Aging journal.

Other Means Besides a Registry Should Be Developed to Evaluate Potential Health Effects of Military Burn Pits’ Toxic Emissions on Exposed Service Members; Data From Burn Pit Registry Could Be Used for Other Purposes, Including Alerting Health Care Providers About Participants’ Concerns

Zika virus could be transmitted by more mosquito species than those currently known, according to a new predictive model created by ecologists at the University of Georgia and the Cary Institute of Ecosystem Studies. Their findings, published today in the journal eLife, offer a list of 26 additional potential candidate species-including seven that occur in the continental United States-that the authors suggest should be the first priority for further research.

The tin foil hat, while fashionable, is an ineffective way of keeping the government’s radio waves from infiltrating and manipulating your mind. In fact, the hat may boost certain radio frequencies, which is OK because there’s no such thing as mind-controlling waves anyway.

Computers can also be programmed to match names and faces, study says

What if walking three hours to get water was a first-world problem?

Cats, you might have heard, cause schizophrenia. Or—more recently—they do nothing of the sort. It’s a decades-long scientific investigation, infrequently punctuated by headline-grabbing stories that definitively claim one or the other, depending on whatever the newest sliver of research indicates.
