A new study reveals that data, materials, and information are often kept secret in academic genetics, hindering scientific progress. The survey found that 47% of geneticists were denied access to resources at least once in the past three years.
Researchers have discovered that specific cellular mechanisms confer resistance to cancer in rats, allowing them to develop pre-cancerous lesions but then return to normal. The study aims to identify genes involved in this resistance, which could lead to breakthroughs in human cancer prevention and therapy.
Researchers at the University of Toronto have developed a novel biofiltration technique that uses bacteria to eliminate odors from pulp mill gas streams. The new technology operates at higher temperatures than existing methods, making it more cost-effective and environmentally friendly.
Researchers found that limiting scar tissue formation enables neurons to regrow and reconnect, leading to substantial recovery of function. This approach suggests potential for therapies to eliminate existing scar tissue at injury sites.
The hospitalist model of inpatient care has achieved many attributes of other medical specialties and is expected to become the dominant model. Studies have shown significant decreases in hospital costs and lengths of stay, with no negative impact on quality measures.
A new study by Frank et al. investigated the relationship between female physicians' personal diet-related habits and their nutrition counseling practices. The findings suggest that physicians who have intentionally altered their own diets are more likely to counsel their patients about nutrition and weight.
The NIH/Office of the Director's panel endorses ERCP for diagnosing suspected ampullary cancers and treating conditions like symptomatic gallstone disease, but emphasizes caution due to potential complications such as pancreatitis.
After severe droughts, wading bird populations surge due to changes in fish populations and nutrient cycles, according to University of Florida researchers. This phenomenon, known as 'pulsed productivity,' occurs worldwide among diverse wading bird species.
A study of 38 children with sickle cell disease found that zinc supplementation significantly increased rates of growth in height and sitting height after 12 months. The treatment reversed growth deficits and delayed development, unlike the control group which showed gradual growth failure characteristic of SCD.
Researchers found that people unconsciously transfer traits from speakers to other humans and even inanimate objects. Using psychology students as volunteers, the study confirmed that spontaneous trait transference is an automatic brain process.
A new method developed by Purdue University's chemical engineers uses artificial intelligence to simultaneously test thousands of formulations, drastically speeding up the discovery process. The technique has the potential to significantly improve catalyst performance and result in substantial economic benefits.
A Yale researcher found that men who witnessed combat are at risk for various current adverse outcomes, including post-traumatic stress disorder and job loss. The study suggests that providing quality mental health care and social services to veterans could mitigate these effects.
A study published in the American Journal of Clinical Nutrition reveals that 67% of convalescent home patients have low serum albumin levels indicative of severe malnutrition. Malnourished patients are also more likely to experience depression and dehydration, highlighting the need for improved nutrition care.
The AAAS Science Journalism Awards recognize outstanding science reporting across various categories. This year's winners include Scott Shane of The Baltimore Sun for his special series on a Johns Hopkins University program to bring much-needed vitamins to the people of Nepal, and Richard Monastersky of The Chronicle of Higher Educatio...
Researchers discovered increased brain activity involving the superior temporal gyrus and inferior parietal cortex when subjects imitated others or were imitated. This suggests that imitation may be linked to empathy and play a crucial role in learning and cultural transmission.
The Look AHEAD trial will examine the effects of a lifestyle intervention program on cardiovascular health in people with type 2 diabetes. The study, which began screening participants in July, aims to enroll 5,000 volunteers and follow them for up to 11.5 years.
A study on Toronto's 'John School' program for male offenders found that 42% of participants were more likely to admit to having a sex problem and 73% admitted guilt. However, the program's results may not be representative of those who use prostitutes in Toronto.
