A new device for collecting and purifying water, developed at The University of Texas at Austin, was inspired by a rose and, while more engineered than enchanted, is a dramatic improvement on current methods. Each flower-like structure costs less than 2 cents and can produce more than half a gallon of water per hour per square meter.

A team led by associate professor Donglei (Emma) Fan in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering developed a new approach to solar steaming for water production –a technique that uses energy from sunlight to separate salt and other impurities from water through evaporation.

A synthetic, non-intoxicating analogue of cannabidiol (CBD) is effective in treating seizures in rats, according to research by chemists at the University of California, Davis.

The synthetic CBD alternative is easier to purify than a plant extract, eliminates the need to use agricultural land for hemp cultivation, and could avoid legal complications with cannabis-related products. The work was recently published in the journal Scientific Reports.

“It’s a much safer drug than CBD, with no abuse potential and doesn...

Neurodevelopmental condition can result from mutations in the noncoding regions of the human genome, research shows. Leveraging artificial intelligence techniques, researchers have demonstrated that mutations in so-called ‘junk’ DNA can cause autism. The study, published May 27 in Nature Genetics, is the first to functionally link such mutations to the neurodevelopmental condition.

The research was led by Olga Troyanskaya in collaboration with Robert Darnell. Troyanskaya is deputy director for genomics at the Flatiron Institute’s Center for Computational Biology (CCB) in New York City and a professor of computer science at Princeton University...

A new study from the University of Eastern Finland shows that a moderately high intake of dietary cholesterol or consumption of up to one egg per day is not associated with an elevated risk of stroke. Furthermore, no association was found in carriers of the APOE4 phenotype, which affects cholesterol metabolism and is remarkably common among the Finnish population. The findings were published in the American Journal of Clinical Nutrition.

Findings from earlier studies addressing the association of dietary cholesterol or egg intake with the risk of stroke have been contradictory...
