Research by Colleen Flaherty reveals pharmaceuticals can stunt growth and result in more male offspring in Daphnia, while combination effects can be lethal. The study highlights the need to consider multiple chemicals in assessing ecological impacts.
Researchers have identified a natural inhibitor of HIV called CEM15, which can stop the virus from replicating. By targeting Vif, a regulatory protein that enables HIV replication, scientists may develop new antiviral treatments.
Researchers at Ohio State University have developed a peptide treatment that inhibits experimental autoimmune encephalomyelitis (EAE) and suppresses the onset of multiple sclerosis-like symptoms. The treatment targets T cells by binding to CD80, preventing their activation and expansion in disease.
A recent study published in the New England Journal of Medicine found that the transmission rate of drug-resistant HIV had more than doubled among patients in North America. The study, which analyzed over 300 patients, revealed a significant increase in the prevalence of viral mutations associated with resistance.
Researchers found that mycorrhizal fungi can increase nitrogen fixation in legumes, improving soil fertility for corn production. Legumes like lablab show promise as a solution to enhance soil fertility without fertilizers.
A new hormone called PYY3-36 has been found to reduce food intake by a third in volunteers, providing potential relief for those struggling with weight problems. The discovery could lead to natural and safe treatments for obesity, potentially identifying specific foods that trigger hunger or developing a tablet with a similar effect.
A study by Penn State researchers found that jet contrails altered the average daily temperature range in the United States during a three-day commercial air shutdown in September 2001. The diurnal temperature range increased by 1.8 degrees Celsius, with daytime temperatures being higher and nighttime temperatures lower without contrails.
The US Marine Corps has begun using a new software system called ANT to schedule fighter air operations, reducing the time spent on planning from hours to minutes. The system balances various factors, including maintenance requirements and resource constraints, to create efficient schedules for aircraft carriers.
Researchers from Penn State College of Medicine developed a new measurement technique to assess norepinephrine release in tissues adjacent to blood vessels. This improvement allows for more accurate data on the hormone's role in vasoconstriction and maintains adequate blood pressure when standing up.
A recent study published in the New England Journal of Medicine found that botulinum toxin type A injections significantly improved muscle tone and function in patients with wrist and finger spasticity after a stroke. The treatment showed sustained effects for at least 12 weeks, with some cases lasting up to 24 weeks.
Infant rats exposed to alcohol developed new synapses in their cerebellum, improving learning skills and compensating for damage. This discovery offers hope for therapeutic intervention and rehabilitation for children affected by prenatal alcohol exposure.
Jake Socha's research on the Chrysopelea paradisi reveals that the snake glides by undulating its body, changing amplitude and frequency while airborne. The study provides new insights into the aerodynamics of these 'flying' snakes, which can glide up to 70 feet across.
Research suggests that altruism, not panic, drives human behavior during disasters. In emergency situations, people prioritize helping others over self-preservation. Clarke's study highlights the importance of community expectations and trust in authorities to guide behavior during crises.
The consortium aims to reveal secrets of the Archaea domain, a grouping thought to include organisms with ancient evolutionary lineages. Researchers will study the structure and function of genes and proteins in this domain.
Research suggests that social activism in groups like ACT UP can help individuals with AIDS and HIV cope better with their medical and psychological problems. Activist group members tend to use more problem-focused coping, have greater knowledge of treatment information sources, and are more integrated into support networks.
A research team led by Dr. Rakesh Kumar has discovered a new form of a protein associated with aggressive forms of cancer, including breast cancer. MTA1s appears to intercept the key protein receptor responsible for communicating with estrogen inside cells.
DuPont scientists Richard Rees and W. Mark Barbour's team developed innovative technologies to minimize falling and flying glass during explosions, while also detecting harmful pathogens in food supplies with the BAX system. Their advancements strengthen global security and protection measures.
