Researchers have created a new class of statistical estimators called 'centroid' estimators, which allow for more accurate predictions from massive datasets. These estimators identify the most representative solution from the data, overcoming limitations of traditional methods like maximum likelihood estimation.
Level I trauma centers have different survival rates for patients with similar injuries, with some centers achieving as high as 99% survival rate and others only 35%. This disparity may be due to variations in resources and processes.
The U.S. Department of Energy Joint Genome Institute has released an upgraded version of its IMG/M metagenome data management and analysis system, featuring five new metagenome datasets from recent studies on termite hindgut microbiota and TM7 microbe. The new system now contains 2,953 reference genomes.
Researchers found a significant decline in per capita visits to U.S. national parks since the late 1980s, correlating with an increase in sedentary activities like video gaming and watching movies. This shift, known as 'videophilia,' has far-reaching consequences for physical and mental health, particularly in children.

A study of US children found that nearly one-third take dietary supplements regularly, with multivitamins and multiminerals being the most common. Supplement use was linked to higher family income, smoke-free homes, and lower body mass index in children.
Two studies find a direct link between increased elective caesarean sections and decreased weekend births in Switzerland and Germany. The research suggests that hospitals schedule births during the week when they are fully resourced and staff is working 'normal' hours, leading to fewer births on weekends.
The SESAME project is developing a unique, integrated computer system that substantially increases data available to coaches during training sessions. This will enable coaches to provide near-instantaneous feedback on athlete technique, improving performance and reducing injury risk.
SMART-1 has mapped the polar regions, surveyed lunar resources, and investigated potential landing sites. The mission has provided clues on the dynamics of ejecta after impact and laboratory experiments have modeled impacts.
A Brown University study has found a significant link between living in damp, moldy homes and depression. The research team analyzed data from nearly 6,000 European adults and found that perceptions of control over the housing environment, combined with mold-related health problems, contribute to an elevated risk for depression.
Research conducted by UC Sociology Professor David Maume found that women are more likely to leave their jobs to attend to their children, while men prioritize work. The study suggests that traditional gender roles persist despite changing attitudes on family responsibilities.
A recent study reveals that minority families moving to new neighborhoods experience equal or better economic gains compared to whites, but white children remain in wealthier areas. The research also finds that staying in one's neighborhood leads to greater economic improvements for white families than non-migrant minorities.
