Researchers found American astronauts and mission control personnel reported lower emotional health scores compared to their Russian counterparts. The study suggests steps NASA can take to boost morale, such as rotating leadership roles among three-person crews.
A new book examines the human aspects of environmental restoration, exploring moral and ethical questions, conflicts over nature definition, and the role of stakeholders. The study suggests ways to resolve restoration conflicts and highlights the importance of stakeholder involvement in sustaining projects.
Dr. Sherwin's research suggests that estrogen replacement therapy prevents some of the decline in verbal memory and ability to learn new material in postmenopausal women. This effect has been observed even in women who underwent surgical removal of their ovaries, which led to a sudden drop in estrogen levels.
The Dartmouth Flood Observatory uses satellite images from NASA's Terra spacecraft to pinpoint flooded areas and provide precise mapping accuracy, aiding United Nations World Food Program staff. The new composite surface images have been used to identify the worst-hit areas of the current flooding in Southeast Asia.
Golgi lipids play a crucial role in regulating protein trafficking, disrupting the organization of the Golgi apparatus and blocking certain proteins from being trafficked. The study found that PLA2 overexpression causes the fragmentation of the Golgi apparatus, similar to changes during mitosis.
A group of Puebloans from the Mesa Verde region is believed to have settled in three ruins on the west side of the Rio Grande River, exhibiting characteristics of the Mesa Verde culture. The site, Pinnacle Ruin, was inhabited by a large group who made a 250-mile journey south after Four Corners collapsed.
A new study found that professional ballet dancers experience injury rates comparable to those of athletes in collision sports, with an average time lost due to injury of 10.5 days. Anxiety and stress management programs can help identify at-risk dancers and reduce injuries.
A six-year study found inhaled steroids to be safe and effective for children with mild-to-moderate asthma, reducing hospitalizations and emergency room visits by up to 43%. The treatment also improved lung growth and reduced symptoms, contradicting previous concerns about long-term risks.
Students from Granby's Sacré-Coeur high school will demonstrate simple water quality tests using lettuce seeds, onion bulbs, and other methods. The demonstration is part of AQUAtox 2000, a global network of students conducting experimental research on water toxicity.
Scientists at Johns Hopkins find that people with repeated sinus infections may carry a mutated CFTR gene, which could increase their risk of chronic sinusitis. The study suggests that patients carrying this mutation may benefit from targeted treatments for sinus infections.
A study by Cornell labor experts found that global capital mobility and ineffective labor laws create a climate where employers threaten to close plants or move investments to avoid unionization. This leads to increased job insecurity and no real wage gains for workers, despite the longest economic boom in US history.
Researchers have measured the comparative bending strength of tiny carbon nanotubes using a technique based on mechanical resonance induced by an oscillating electrical voltage. The study provides information that will help materials scientists select the best variety of nanotube for new applications.
Cystic fibrosis patients' lungs are infected primarily with bacterial biofilms, which are resistant to antibiotic treatment and cause damage to the lungs. A new test developed by University of Iowa researchers shows that Pseudomonas aeruginosa produces signaling molecules indicative of a biofilm state.
Helen M. Berman and Wilma K. Olson receive the honor for their major contributions to molecular biophysics, with a focus on nucleic acids and macromolecular solvation. The awards recognize their dedication to advancing knowledge in biophysics and education.
A recent UB study found no association between high-normal iron levels and risk of death due to cardiovascular disease, coronary heart disease or heart attack. However, black men with low levels of excess iron were at three times the risk of death from any cause.
Streptococcal bacteria use the bacterial capsule containing hyaluronic acid to bind to epithelial cells of the pharynx and cause sore throats. Suppression of CD44 levels or use of antibodies/ exogenous hyaluronic acid can block this interaction.
Research demonstrates that increased Akt1 function is sufficient to produce tetraploid smooth muscle cells in hypertensive or aging arteries. Cyclin B degradation is prematurely triggered in these cells, allowing for extra rounds of DNA synthesis and cell growth.
Researchers have sequenced the Ureaplasma urealyticum genome, revealing a novel metabolic system and 652 genes with unknown functions. The discovery will aid in understanding how the bacterium causes disease and may lead to better treatments.
