Using floodwaters to weather droughts
Using a new computer framework, scientists are able to project future floodwaters under a changing climate. The approach could help California water managers plan for and redirect floodwaters toward groundwater aquifers, alleviating both flood and drought risks.

Cracking the code of the Dead Sea Scrolls
The Dead Sea Scrolls, discovered some seventy years ago, are famous for containing the oldest manuscripts of the Hebrew Bible (Old Testament) and many hitherto unknown ancient Jewish texts. But the individual people behind the scrolls have eluded scientists, because the scribes are anonymous. Now, by combining the sciences and the humanities, University of Groningen researchers have cracked the code, which enables them to discover the scribes behind the scrolls.

Scientists capture first ever image of an electron's orbit within an exciton
In a world-first, researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have captured an image showing the internal orbits, or spatial distribution, of particles in an exciton - a goal that had eluded scientists for almost a century. Their findings are published in Science Advances.

Stress and death in female baboons
Female baboons lead extremely challenging lives that leave some of them with chronically high levels of glucocorticoid stress hormones. A new study appearing 21 April in Science Advances shows that female baboons with high life-long levels of glucocorticoids, the hormones involved in the 'fight or flight' response, have a greater risk of dying than those with lower levels. Modeling showed the high stress levels may cost 25 percent of lifespan.

AI algorithms can influence people's voting and dating decisions in experiments
In a new series of experiments, artificial intelligence (A.I.) algorithms were able to influence people's preferences for fictitious political candidates or potential romantic partners, depending on whether recommendations were explicit or covert. Ujué Agudo and Helena Matute of Universidad de Deusto in Bilbao, Spain, present these findings in the open-access journal PLOS ONE on April 21, 2021.

A "finger phantom" to train treatment of trigger finger using ultrasound guidance
Researchers have made a 3D-printed anatomical finger model, embedded in ballistic gelatin, as a low-cost ultrasound training phantom for procedural guidance of trigger finger injections. Though the finished product looks like a brick, the ultrasound image of the bones, ligament, tendons and the A1 annular pulley inside it appear anatomically and sonographically similar to images observed in a human finger, both pre- and post-injection. Ultrasound shows the anatomical landmarks as the needle is inserted.

A growing problem of 'deepfake geography': How AI falsifies satellite images
Using satellite photos of three cities and drawing upon methods used to manipulate video and audio files, a team of researchers led by the University of Washington set out to identify new ways of detecting fake satellite photos and warn of the dangers of falsified geospatial data.

Record-breaking flare from Sun's nearest neighbor
A team of astronomers including Carnegie's Alycia Weinberger and former-Carnegie postdoc Meredith MacGregor, now an assistant professor at the University of Colorado Boulder, spotted an extreme outburst, or flare, from the Sun's nearest neighbor--the star Proxima Centauri. Their work, which could help guide the search for life beyond our Solar System, is published in The Astrophysical Journal Letters.

Verbal fluency deficits in multiple sclerosis may reflect impaired language ability
"Our results indicate that language ability and domain-general factors were predictive of verbal fluency in individuals with MS," summarized Dr. Chiaravalloti. "Specifically, language ability played a significant role. This could indicate that verbal fluency deficits in MS reflect underlying language impairment," she added, "Our findings further demonstrate the need for more comprehensive examination of language in people with MS."

Insurance isn't enough for women at high risk of breast cancer
Women at high risk of breast cancer face cost-associated barriers to care even when they have health insurance, a new study has found. The findings suggest the need for more transparency in pricing of health care and policies to eliminate financial obstacles to catching cancer early.

Dating in a jungle: Female praying mantises jut out weird pheromone gland to attract mates
Praying mantises are bizarre insects, yet many aspects of their biology remain unknown. Meanwhile, scientists from the Ruhr-University and the Bavarian State Collection of Zoology discovered that females of a South American species protrude a Y-shaped organ on their backs to release pheromones and attract males. Found in none of the over 2,500 species of praying mantises worldwide, the behaviour is reported for the first time in the peer-reviewed scientific Journal of Orthoptera Research.

Ingredient in Indian long pepper shows promise against brain cancer in animal models
Piperlongumine, a chemical compound found in the Indian Long Pepper plant, is known to kill cancerous cells in many tumor types. Now an international team including researchers from Penn has illuminated one way in which the piperlongumine works in animal models -- and has confirmed its strong activity against glioblastoma.
