Researchers at NIAID have produced the first high-resolution genetic map of Plasmodium falciparum, the deadliest malaria parasite. The map provides a framework to accelerate genome sequencing efforts, enabling scientists to locate genes important for drug resistance and disease severity.
Dutch researchers use calculations to show that tubular-shaped vortices can form within areas of air turbulence, causing water droplets to congregate at the edge and leading to rain precipitation. This discovery contradicts previous assumptions about cloud formation and supersaturation.
Researchers are examining whether high doses of vitamin D can stop the progression or destroy prostate cancer. If successful, patients may be able to delay aggressive treatment and stay on the treatment indefinitely.
Yale researchers have created a new method to record electrical activities within living cells, providing insights into degenerative neurological diseases like Parkinson's. The technique, which allows scientists to study inaccessible parts of cells, has already led to findings on how neurons learn and remember.
Researchers discovered HIV can replicate in resting T cells, previously thought to be uninfected. The virus spreads quickly through activated T cells as well, but these infected cells are harder to reach with current therapies.
Researchers found that lower total cholesterol levels require only dietary changes, while higher levels necessitate medication. The combined strategies are effective in reducing cholesterol across all surveyed individuals, regardless of their initial cholesterol levels.
Despite rising numbers of female scientists, senior women researchers often experience isolation and frustration due to limited administrative power and respect from colleagues. A 'quiet revolution' is underway at institutions like MIT and Harvard as they address gender discrimination and promote women's careers.
Early findings from a national study suggest that many women with chest pain are being misdiagnosed due to minor coronary artery blockages. Researchers found that nearly one-fourth of women with 'normal' coronary arteries had detectable disease, increasing their risk of hospitalization and poor outcomes.
A team of scientists, including Montana State University's David Varricchio, discovered a wealth of information about skeletal changes in dinosaurs. The study found that some lineages remained relatively static for tens of millions of years, while others changed rapidly, providing new insights into dinosaur evolution.
A two-year study of 309 hypertensive urban African American men found that personalized care improved blood pressure control rates by an average of 39%. The team intervention showed a slightly higher improvement rate compared to the standard education and referral group.
Rainforest fragments experience 'edge effects' that hinder seed germination, with seeds being three to seven times less likely to sprout than those in continuous forests. Inbreeding can further reduce reproduction rates, threatening the survival of populations in forest fragments.
A study of 2,708 participants found that beta-blocker bucindolol did not reduce death from heart failure. The results contrast with other trials and raise questions about the use of beta-blockers in advanced heart failure.
