Smarter models, smarter choices

Artificial intelligence isn't perfect. In fact, it's only as good as the methods and data built into it. Researchers at the University of Delaware have detailed a new approach to artificial intelligence that builds uncertainty, error, physical laws, expert knowledge and missing data into its calculations and leads ultimately to much more trustworthy models.

The Milky Way galaxy has a clumpy halo

Astronomers at the University of Iowa have determined our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars. The halo also may be where matter unaccounted for since the birth of the universe may reside. Results published in the journal Nature Astronomy.

Trees bring benefits to society, regardless of their origin

Ultraviolet shines light on origins of the solar system

In the search to discover the origins of our solar system, an international team of researchers, including planetary scientist and cosmochemist James Lyons of Arizona State University, has compared the composition of the sun to the composition of the most ancient materials that formed in our solar system: refractory inclusions in unmetamorphosed meteorites.

UMD-led study shows fear and anxiety share same bases in brain

The report by an international team of researchers led by Alexander Shackman, an associate professor of psychology at UMD, and Juyoen Hur, an assistant professor of psychology at Yonsei University in Seoul, South Korea, provides new evidence that fear and anxiety reflect overlapping brain circuits. The findings run counter to popular scientific accounts, highlighting the need for a major...

Unique program aims to educate Muslim teens on HIV prevention

Cultural taboos may leave Muslim American adolescents uninformed about romantic relationships and sex, placing them at risk of HIV and other sexually transmitted infections (STIs). A sex education program designed specifically for Muslim teens -- with a foundation in Islamic morals and values -- is reported in the November/December issue of The Journal of the Association of Nurses in AIDS Care...

Untreated sleep apnea is associated with flu hospitalization

As we approach flu season, adults with obstructive sleep apnea may want to take extra precautions. A study published online as an accepted paper in the Journal of Clinical Sleep Medicine is the first to find that patients with sleep apnea who did not use CPAP therapy were more likely to be hospitalized with the flu.
