A new study found that women at high risk for breast cancer who are also anxious and lack self-control are less likely to get a mammogram. Researchers suggest problem-solving training may help address this issue among the most distressed women.
Researchers used imaging to 'movie' the interaction between a T cell and an antigen-presenting cell, revealing specific protein rearrangements that form an immunological synapse. This structure determines whether a T cell will respond to an antigen.
The USGS has successfully released captive-reared puaiohi birds into the wild, with four chicks having already fledged. This is a significant step towards the species' recovery, with biologists optimistic about re-establishing a self-sustaining population.
Phobic disorder significantly affects individuals with chronic diseases, hindering ongoing medical care. A study reveals that nearly half of those without regular medical care have active psychiatric disorders.
Coral reefs are experiencing extensive bleaching due to gradual warming of ocean temperatures. A new study found that heat damage to symbiotic algae is degrading their ability to convert light into utilizable energy. The damaged algae, including the D1 protein, impair photosynthesis and lead to coral expulsion.
A five-year study of female monkeys will examine how chronic, low-level stress affects brain function and may lead to depression. The research aims to understand why some individuals are more susceptible to depression than others and may provide insights into treating depression in humans.
A study found that reducing hostility in coronary heart disease patients leads to improved blood pressure and reduced risk of heart disease. The intervention, which included listening skills and techniques to avoid cynicism and anger, resulted in lower diastolic blood pressures among participants.
Daily contact from weight counselors can help dieters maintain consistency in tracking food intake, leading to better weight loss outcomes. The study found that increased therapist contact significantly improved participants' ability to avoid gaining weight during the holidays.
Researchers found that head trauma impairs brain cells' ability to detect and repair DNA damage, leading to weeks of prolonged cell death. The study suggests that the body's surveillance system breaks down after an injury, making it difficult for cells to recover.
The discovery of BLyS, a natural component of the immune system, holds promise for treating immune deficiency disorders, enhancing vaccine effectiveness, and targeting certain types of leukemia and lymphoma. The substance stimulates B cell growth and antibody production, addressing a long-standing puzzle about monocytes' role in the im...
A new study by researchers at UCLA found that pregnant women with positive psychological resources tend to have healthy-weight infants. The study, which analyzed data from 230 pregnant women, suggests that a woman's ability to adapt to the challenges of pregnancy is crucial to the outcome.
A new study suggests that hope plays a vital role in maintaining the health of HIV-positive men who have lost a loved one to AIDS. The researchers found that optimistic expectations and feelings of control over the disease are associated with a slower rate of progression of HIV-related illness.
A protein called PEDF has been shown to halt excessive blood vessel growth in the eye, potentially treating diabetic retinopathy and macular degeneration. Researchers found that increasing PEDF levels could slow vision deterioration and prevent new vessels from overgrowing.
Researchers at University of Chicago discover that a single amino acid change in viral protein ICP0 prevents herpes virus from entering nervous system. The finding reveals a potential new target for herpes vaccines or future therapies.
A study of 1,504 pairs of parents and children found that enjoyment of physical education classes and family support were key factors in influencing levels of physical activity. The research highlights the need for schools to develop programs that maintain high participation and enjoyment throughout the school career.
Researchers have identified the molecule transported by Rim protein in photoreceptor cells, a key factor in the development of Stargardt's disease and age-related macular degeneration. By understanding this process, scientists may be able to develop new treatments to slow or prevent the progression of these diseases.
A new study found that women have limited knowledge of their mortality risks, particularly regarding heart disease and lung cancer. Women aged 55-74 were unaware of the deadliest cancer in this age group, while older women knew less about what kills them than other age groups.
Researchers at Technion-Israel Institute of Technology have discovered that small lasers can produce tiny optical vortices, also known as whirlpools of light, which could be used to transmit information at high speeds over long distances. The findings have practical applications in improving optical fiber communications and may also be...
