Researchers have discovered that bacteria can enter immune system cells through a pore in the cell membrane, triggering an immune response without activating Toll-like receptors. This finding offers new perspectives for developing human vaccines and drugs that target inflammatory responses in autoimmune diseases like rheumatoid arthritis.
Researchers have built a new model that suggests neutron star surfaces run hotter than previously thought, releasing 10 times more heat. This helps explain the observed frequency of superbursts on such stars' surfaces, but scientists still don't know why they occur annually.
Research found that students who watched more TV on 9/11 had higher levels of stress in their dreams, while those who talked to family and friends experienced better processing of traumatic events. The study suggests that repeated exposure to horrific images through TV may amplify stress and trauma.
Researchers have identified ten areas of the wild tomato genome associated with resistance to grey mould. The discovery could lead to the development of new, pesticide-free tomato varieties.
Researchers created ultra-small microreactor chips that increase chemical reaction rates by up to 1.7 times, reducing safety risks and increasing efficiency. The miniaturized Total Analysis System (µTAS) is now a feasible future technology.
An international science team led by LSU professor Robert Twilley is developing an environmental observation system for India to help reduce climate-related risks. The system will provide a scientific foundation for long-term government policies aimed at meeting international accords on greenhouse gas emissions.
Researchers at Rowan University and Penn Medicine developed a high-accuracy method to diagnose early-stage Alzheimer's using EEG signals. The test, which can be done in a physician's office, has an accuracy rate of 82-85% and may provide earlier treatment and improved quality of life for those affected.
The Netherlands Organization for Scientific Research found that CO2 capture and storage can avoid up to 80-110 million tonnes of CO2 emissions annually. The technology has significant potential in various sectors, including energy, industry, and transport.
The U.S. Department of Energy's Argonne National Laboratory has developed emission control strategies to meet air quality goals for the 2008 Summer Olympics in Beijing. The modeling study, funded by the EPA, suggests that regional pollutants and ozone build up over several days due to meteorology and topography.
X-ray scattering techniques have been successfully applied to determine how dissolved metal ions interact in solution, revealing their structures and long-range interactions. This research helps understand how metal ions behave in the environment and has implications for predicting reactions to metal contaminants.
Dutch researcher Saikat Mazumder developed a method to estimate CO2 storage in coal using CT scans, improving understanding of crack patterns and gas absorption. Coal was found suitable for filtering out carbon dioxide from waste gases and storing it.
Zimbabwean smallholder farmers in semi-arid regions face food shortages due to limited fertilizer use. Research by Bongani Ncube found that nitrogen availability is the key factor improving cereal yields. Crop rotation also showed promise, with leguminous crops doubling sorghum yields.
A new study by Columbia University's Mailman School of Public Health has found that gay and bisexual men are at a higher risk for eating disorders than heterosexual men. The study surveyed 516 New York City residents, including 126 straight men, and found that over 15% of gay or bisexual men had suffered from anorexia, bulimia, or bing...
Researchers have developed a new method for testing the reliability of tests, improving the accuracy of risk estimates and enabling better product quality control. The new approach takes into account the severity of errors, providing a more realistic measure of reliability.
A new study published in Employee Responsibilities and Rights Journal finds that homosexuals are no more disruptive to military life than their heterosexual counterparts. The study, led by Dr. Debbie Knapp, challenges the U.S. military's reasoning behind discharging gay soldiers under the 'Don't Ask, Don't Tell' policy.
Up to 65% of Quebec Cree preschoolers are overweight or obese, according to a recent study published in the American Journal of Public Health. High waist circumferences and low physical fitness levels were also found among elementary school students.
