Yves Meyer, a French mathematician who pioneered wavelet theory, has been awarded the 2017 Abel Prize. The Norwegian Academy of Science and Letters bestowed the award for Meyer's "pivotal role" in the development of the mathematical theory of wavelets, which is used in a variety of applications, such as medical diagnostics.
Mars volcano Arsia Mons went dormant about 50 million years ago, around the same time that Earth's dinosaurs became extinct, according to a new NASA computer model. Researchers pieced together the volcano's history using high-resolution images taken by the Mars Reconnaissance Orbiter, according to findings presented at the Lunar and Planetary Science Conference in Texas and published in Earth and Planetary Science Letters.
Fallout from nuclear weapons testing in Kazakhstan during the 1950s was more widespread and devastating than previously disclosed by the Soviet Union, according to newly uncovered classified documents. The documents by Moscow's Institute of Biophysics were found in the Institute of Radiation Medicine and Ecology's archive and show the fallout was four times that of the Chernobyl disaster.
Sea otters and their ancestors may have been using tools for millions of years, long before many other marine mammals, according to a genetic study published in Biology Letters. Researchers also found that the use of tools is innate in otter pups.
A team of mathematicians has created software that allows people with virtual-reality headsets to explore a world of hyperbolic spaces, according to papers published on arXiv. "It feels like the entire universe is within a sphere that is maybe within a couple meters' radius," said Henry Segerman, who collaborated on the project.
Australian researchers found that children whose mothers took docosahexaenoic acid supplements daily during pregnancy had similar IQ test scores, language skills, and academic and executive functioning at age 7, compared with those whose mothers received placebo. The findings in the Journal of the American Medical Association also showed slightly higher perceptual reasoning scores but significantly more behavioral problems and executive dysfunction among those in the DHA group.
Doxycycline was as effective as the oral steroid prednisolone in treating short-term blisters in bullous pemphigoid, according to a study in the Lancet. Patients suffering from the rare blistering disease had significantly fewer side effects with the antibiotic as well, researchers noted.
The National Institutes of Mental Health has awarded a $417,285 grant to an Oregon researcher studying autistic workers. Dora Raymaker also received a $50,000 grant promoting diversity in science from Portland State University, where her research is based.
NASA has awarded a $1.4 million grant to the University of Colorado to study drought conditions in California. The study will use data collected by NASA satellites to examine California's recent severe drought from 2012 to 2015.
