The latest rescue took place last month, when sherriff’s deputies found a missing 93-year-old woman in a dark field in Missouri – using a DJI drone with a thermal imaging camera. That brings the total to more than 500 lives saved by drones, according to DJI’s project counting the lives that would have been lost without direct intervention of drone technology.

DJI began the project back in 2017 when they published a paper called “Lives Saved: A Survey of Drones in Action” which found that even back in 2016 – 2017, drones saved lives at the rate of nearly 1 per week. That first paper has evolved into the DJI Drone Rescue Map, which allows viewers to explore rescue incidents all over the world.

The project was started in response to bad press about drone technology. Research has shown that a negative drone event – even one that later is found to be inaccurate or untrue – averages more than 10x the publicity than a positive drone event. That’s a problem for a new industry struggling against negative public perception and fears over privacy issues and misuse of drone technology.

Rusted iron pipes can react with residual disinfectants in drinking water distribution systems to produce carcinogenic hexavalent chromium in drinking water, reports a study by engineers at UC Riverside.

Chromium is a metal that occurs naturally in the soil and groundwater. Trace amounts of trivalent eventually appear in the and food supply and are thought to have neutral effects on health. Chromium is often added to iron to make it more resistant to corrosion.

Certain can change chromium atoms into a hexavalent form that creates cancer-causing genetic mutations in cells. This carcinogenic form of chromium was at the heart of a lawsuit in California’s Central Valley by Erin Brockovich, which became the subject of an Oscar-winning movie.

A questionnaire developed by XPRIZE and Deep Longevity claims to be able to accurately predict your psychological age by using artificial intelligence (AI) to analyze your answers, which theoretically should fall close to your chronological age. The questionnaire is developed from a study published in Aging that used AI in an attempt to identify key hallmarks of psychological aging and the top risk factors that affect mortality.

While the questionnaire seems like a fun insight into whether you’re an old soul or a young gun at heart, there is an important scientific basis for an age-predicting AI. The newly developed technology represents the first AI aimed solely at using psychological aspects to predict age. The researchers hope it can contribute to understanding the role psychological clocks play in overall aging, as well as improving mental health and the feeling of youth.

“For the first time, AI can predict human psychological and subjective age and help identify the possible interventions that can be applied in order to help people feel and behave younger,” said Alex Zhavoronkov, PhD, founder and CLO of Deep Longevity and co-author of the study, in a statement.

A new study has found that a novel T cell genetically engineered by University of Arizona Health Sciences researchers is able to target and attack pathogenic T cells that cause Type 1 diabetes, which could lead to new immunotherapy treatments.

The immune system fights bacteria, viruses and other pathogens by utilizing several types of T , all of which have receptors that are specific to particular antigens. On killer T cells, the receptor works in concert with three signaling modules and a coreceptor to destroy the . Michael Kuhns, Ph.D., an associate professor in the UArizona College of Medicine—Tucson Department of Immunobiology, copied the evolutionary design to engineer a five-module , or 5MCAR, T cell.

“The 5MCAR was an attempt to figure out if we could build something by biomimicry, using some of evolution’s natural pieces, and redirect T cells to do what we want them to do. We engineered a 5MCAR that would direct killer T cells to target autoimmune T cells that mediate Type 1 diabetes,” said Dr. Kuhns, who is member of the UArizona Cancer Center, BIO5 Institute and Arizona Center on Aging. “So now, a killer T cell will actually recognize another T cell. We flipped T cell-mediated immunity on its head.”
