Qaisar Shafi's research proposes two distinct components of dark matter, with the 'cold' component residing in galaxy haloes and the 'hot' component gravitationally trapped by large-scale structures. This new understanding could guide experimental work and incorporate dark matter into models of the universe.
Researchers at the University of Florida are adapting space-age technology to improve citrus farming efficiency in the state. The team, led by Professors Jodie Whitney and John Schueller, is using precision agriculture techniques to help farmers optimize their fields and reduce costs.
A new study by UCSF researchers found that smoking in movies has returned to levels comparable to the 1960s, with pro-tobacco portrayals remaining prevalent. The incidence of smoking in films increased dramatically during the 1990s, exceeding real smoking rates and reinforcing misleading images.
A new scheduling system for the Atlantic Coast Conference (ACC) uses algorithms to generate over 300 million possible schedules before arriving at a single optimal solution. The system provides numerous benefits, including ensuring fair matchups, convenient fan attendance, and rest time for athletes.
Researchers developed a mini respirator for mutant mice, increasing survival rate by over 50 percent. The machine uses oscillated pressure to inflate and deflate the lungs, addressing limitations of conventional respirators in small animals.
A five-year educational campaign in Thailand has dramatically cut HIV infections and sexually transmitted diseases among young army draftees. The program, which promoted condom use, reduced the HIV rate by a factor of five and STDs by a factor of ten among those studied.
A study found that individuals taking nisoldipine had a higher rate of fatal and non-fatal heart attacks compared to those taking enalapril, sparking concerns about the safety of calcium antagonists for certain populations. The American Heart Association advises against panic and emphasizes the need for consultation with physicians.
Researchers found that echo-like sounds made by the inner ears of homosexual and bisexual women are weaker than those of heterosexual women, suggesting masculinization of brain structures responsible for sexual preference. The study indicates the potential value of non-invasive windows into brain development and sexual differentiation.
A USC/Norris study reveals how genistein suppresses the mammalian stress response, preventing cancer growth in cell cultures and animal models. This mechanism may provide insight into soy's anti-cancer effects and its potential as an effective agent.
