A University of Pittsburgh study found no overall increase in cancer deaths among TMI residents between 1979 and 1998. However, a slight increase in lymphatic and hematopoietic cancers was observed in women, related to everyday background radiation exposure.
NASA's space station has successfully grown its first commercial farming experiment - soybeans grown in microgravity. The experiment, conducted by DuPont, aims to accelerate crop development and improve crop yields.
A $3.3 million NIH-funded grant will test whether changing the afternoon environment can increase physical activity, improve diets, and reduce body fat in third-graders.
A genetic variant in the CYP2B6 gene has been found to impact smoking cessation success. Researchers discovered that smokers with a decreased activity variant of this gene were more likely to relapse during treatment. The study also suggests that bupropion may be more effective for female smokers, particularly those with the polymorphism.
A recent study published in Psychosomatics found that HIV-positive patients who perceive their illness as a 'punishment' experience lower self-esteem and increased depression. The research highlights the need for addressing psychosocial issues, such as punishment beliefs about HIV, on self-care and medical outcomes.
A study published in Psychosomatics found that American college students are more likely to develop body image concerns and be preoccupied with their appearance than German counterparts. The data suggests an association between poor body image and low self-esteem, depression, anxiety, and obsessive-compulsive disorder.
A recent study found that only a small proportion of individuals produce large numbers of offspring that survive, threatening the genetic diversity of marine fish populations. With millions of fish remaining, even a few hundred capable breeders can be insufficient to sustain genetic variability.
New theory explains why circumstellar Keplerian disks are stable around Be stars, contradicting previous model's predictions. The Magnetically Torqued Disk model suggests a narrow range of star types can form detectable disks.
Researchers found a significant increase in Delta FosB protein in the striatum of adolescent mice following chronic exposure to psychostimulants. This adaptation may contribute to increased sensitivity to addiction and therapeutic use of these medications in adolescents.
Researchers will use infrared spectroscopy to identify mutant genes affecting plant cell wall architecture in Arabidopsis and maize. The goal is to determine the function of all genes involved in plant cell walls, potentially leading to improvements in food-derived health benefits and product durability.
Researchers have developed a new diagnostic tool using PET scans to detect Alzheimer's disease more accurately. By analyzing brain activity, the scans can identify changes that occur before patients themselves may recognize problems.
Howie Choset's snakebot technology can navigate through three-dimensional terrains with enhanced flexibility and 'reach' ability. The robot's hyper-redundant mechanisms enable it to thread through tightly packed spaces without disturbing the surrounding areas.
A recent study found that depression one month after coronary artery bypass surgery is a significant risk factor for continued cardiac problems. The research suggests that evaluating patients for depression after surgery and providing treatment may enhance long-term outcomes.
A study found that White Americans' fruit and vegetable consumption rose by 11 percent when a supermarket was nearby, whereas black Americans showed a smaller increase. The research highlights the importance of environmental factors in shaping dietary habits.
A study of 156 spouses of people with lung cancer found that those using moderate levels of religious coping had lower depressive symptoms. High levels of religious coping were linked to higher depression scores, suggesting a complex relationship between the two.
Researchers have found that delta opioid peptide may help protect brain cells from the ravages of Parkinson's disease by inducing a state of suspended animation. The compound was shown to reduce brain damage and neurological deficits in animal models of stroke, suggesting potential benefits for patients.
A clinical trial using fMRI found that secretin activates the amygdala, a brain region involved in social integration and implicated in autism. The study suggests that secretin may have a role in modulating certain social behaviors in humans.
Research suggests that tobacco smoke exposure can transform follicular lymphoma into an aggressive large cell lymphoma with poor prognosis. Genetic mutations in the p53 tumor suppressor gene and microsatellite instability may play a role in this process.
