A new study suggests that selfish individuals have a strategy called 'Selfish Punisher' that exploits altruists and punishes other selfish individuals, making it a successful approach in Darwinian terms. Altruism can evolve by natural selection as long as its collective advantage outweighs its local disadvantage.
A new study suggests that therapies inhibiting IGF-1 signaling in prostate cancer may not work as expected in tumors with a compromised p53 gene. The research, conducted by investigators at Fred Hutchinson Cancer Center, found that eliminating IGF-1R expression led to hyperplastic cell growth and proliferation in mouse prostates.
A study by Eric Post at Penn State has found that global warming is causing trophic mismatch in West Greenland's caribou population, where plant growth is advancing ahead of animal births. This phenomenon, linked to climate change, may hinder the species' ability to adapt and persist.
A Yale University study found that individuals who used a computer-assisted training program in addition to traditional counseling stayed abstinent significantly longer. The subjects had fewer positive drug tests at the conclusion of the study.
SAGE will publish the Journal of School Nursing (JOSN) and the NASN Newsletter, providing a forum for advancing school nursing practice. The partnership aims to improve the health and educational success of children and youth through evidence-based research and clinical articles.
The journal showcases two classic methods for chromosomal analysis, including a protocol for mapping protein distributions on polytene chromosomes and a karyotyping technique for mouse cells. These approaches allow researchers to study gene regulation and chromatin structure at high resolution.
The UK's NICE rejected abatacept for treating rheumatoid arthritis due to its estimated cost-effectiveness ratio. Despite being one of the most effective treatments, it was deemed too expensive for the NHS. The decision has raised concerns about balancing clinical efficacy with resource constraints.
Shire will present efficacy and safety results for its ADHD treatments, including lisdexamfetamine dimesylate, methylphenidate transdermal system, and guanfacine extended release. The presentations aim to contribute to the growing body of research on ADHD treatment options.
The Gamma-Ray Large Area Space Telescope (GLAST) will study the gamma-ray sky in unprecedented detail, revealing extreme astrophysical processes like pulsars and supermassive black holes. The mission aims to comprehend the origin and distribution of dark matter.
A University of Missouri study found that organizational trust is key to successful joint business ventures. Researchers studied 114 international collaborations and found that trust at three levels: inter-organizational, internal reliance, and among collaborative individuals, was crucial for success.
A new study finds nearly one-third of children in the Pediatric Intensive Care Unit (PICU) experience hallucinations or delusions, which are associated with higher risk of post-traumatic stress symptoms. The study suggests that sedation and physical environment may play a role in reducing these symptoms.
A recent study published in the SLEEP journal found a consistent global link between short sleep duration and increased risk of obesity. The research analyzed data from over 630,000 participants across 29 countries, revealing that both children and adults who slept less than average had a higher likelihood of being obese.
Two studies shed new light on eye health issues: the role of antioxidant supplements in preventing cataract development and their relationship to mortality. Glaucoma research also explores the link between cerebrospinal fluid pressure and optic nerve damage, revealing a potential contributor to glaucoma's progression.
A study published in The Lancet finds that 4 out of 5 high blood pressure-related deaths occur in the developing world. The research estimates a worldwide burden of disease attributable to hypertension, with 7.6 million premature deaths and 92 million disability-adjusted life years attributed to HBP.
A new technique from Carnegie Mellon University speeds up critical steps in automated biological screening methods, improving accuracy and reducing time requirements. The method also enhances the efficiency of the belief propagation algorithm, applicable to fields beyond biology.
A recent study found that coronary heart disease mortality rates among younger women under 50 are increasing despite overall declines since the 20th century. Factors such as high levels of smoking, obesity, and a lack of exercise may be contributing to this trend.
A study found that older adults with higher levels of nighttime fragmentation, respiratory symptoms, diabetes, and pain were more likely to nap. Naps can be a reflection of needed sleep, suggesting that health problems may be contributing to disrupted nighttime sleep.
Research suggests tricyclic antidepressant desmethylimipramine can restore vagal function and reduce intestinal inflammation in individuals with inflammatory bowel disease and depression. Decreased vagal signaling and increased macrophage presence in the intestine are key factors in increasing susceptibility to intestinal inflammation.
Researchers found that prompt antibiotic treatment of H. pylori infections can reverse damage to the stomach lining and prevent gastric cancer. Treating mice with antibiotics at an early point of infection delayed the development of severe lesions that can lead to cancer.
Researchers at Stanford University have synthesized a compound that can be tailored to flush HIV out of hiding and into the crosshairs for targeted destruction. By synthesizing prostratin and DPP, two compounds found in plants, scientists can now tackle the virus more effectively.
Researchers identified a compound that enhances ACE2 enzyme activity, dramatically lowering blood pressure and improving heart function. The compound also prevents damage to the heart and kidneys in hypertensive rats, offering new hope for treating cardiovascular disease.
A genetic breakthrough explains dangerously high blood glucose levels in healthy individuals by identifying a DNA sequence that controls variability. This discovery holds out hope for 'personalized medicine' and may lead to customized treatment based on an individual's unique genetic structure.
A significant difference in sleep disturbances was found between Alzheimer patients and their caregivers. Poor sleep quality was linked to various health problems such as depression, daytime sleepiness, and increased risk of obesity, cardiovascular disease, and diabetes.
Researchers believe immunotherapy could curb the immune response and induce tolerance to peanut allergens, potentially reducing severe reactions. In the next five years, some form of immunotherapy is expected to be available for individuals with peanut allergy.
