A recent study challenges the long-held link between Ashkenazi Jewish ethnicity and increased risk for hereditary breast cancer. The research highlights methodological flaws and unintended consequences, including disparities in access to care and stigmatization. For non-Ashkenazi Jewish women, similar prevalence studies are lacking.

The study highlights a major inflammatory pathway and identifies potential targets for therapies, including the manipulation of IL-23 pathway.
A study by Yale researchers has identified a gene variant associated with Crohn's disease, which may offer new therapeutic targets for the condition. The discovery was made in collaboration with international researchers who scanned the genome of over 300,000 individuals to identify genetic components of inflammatory bowel disease.
The University of Minnesota Center for Drug Design has been awarded a 5-year grant to study cyanide antidotes. Researchers aim to develop faster-acting treatments that can be taken before a cyanide attack, with the goal of improving outcomes for long-term survivors of acute poisoning.
Rimonabant reduces bodyweight and improves blood glucose control in patients with type 2 diabetes. The study suggests that rimonabant could be used as a new treatment option for patients who have not responded to standard treatments.
A large majority of Americans are willing to make significant changes in their lives and cooperate with public health officials' recommendations during a pandemic flu outbreak. However, many would face critical work-related problems and financial concerns if they had to stay home from work for an extended period.
A year-long study found that postmenopausal women who exercised regularly had about half the risk of colds compared to non-exercisers. Moderate exercise, such as brisk walking, boosted immune function and reduced markers of breast-cancer risk.
A study found that caesarean rates vary substantially between and within countries, with some populations having little or no access to surgical delivery. The researchers estimate that 80,000 births had an unmet need for surgical delivery, representing 15% of global maternal deaths in 2000.
The use of videoconferencing in a twinning program between Jordan and Canada improved patient care, compliance, and trust. The program showed positive impacts on treatment changes, second opinions, and introduction of new concepts in pediatric oncology.
Researchers at the University of Calgary discovered that elite goalies should focus their gaze directly on the puck to make a save. This 'Quiet Eye' phenomenon allows goalies to successfully block shots over 75% of the time.
A physician-led organization believes that regaining control of training would lead to improved morale among doctors. The GMC needs to modernize its processes to enable independent functioning under its direction. This, in turn, could result in better quality of care and public trust.
Joseph Dwyer is studying the phenomenon of runaway breakdown in lightning, which creates high-energy electrons that make x-rays. His research aims to understand how lightning works and could lead to new discoveries.
A new genetic link has been found for Crohn's disease, revealing a crucial target for drugs that might better manage the condition. The discovery of a specific gene variant confers significant protection against IBD, suggesting therapies targeting the IL-23 pathway may lead to more individualized treatments.
Astrophysicists have resolved a long-standing issue with the Big Bang theory by studying gas movements in stars. Computer models revealed that low mass stars destroy helium 3 before it can be released into space, resolving the discrepancy.
The Lancet evaluates the five candidates vying for the Global Fund's top job, with Hilde Johnson and Michel Sidibe emerging as leaders. The Editorial highlights the importance of partnership, evaluation, and accelerated results in optimizing grant performance and mobilizing resources.
A new study by Olaf Sporns and Max Lungarella provides insight into how the brain operates and sheds light on its evolution. The researchers created a mathematical framework that quantifies the relationship between neural and behavioral processes, revealing that the brain and body are interconnected.
Researchers created a mathematical code that describes how low-mass stars destroy helium-3 during evolution. This process resolves the discrepancy between helium-3 abundance and the Big Bang theory, providing insights into the universe's early stages.
Researchers at the University of Pittsburgh are exploring the use of fat-derived stem cells for breast reconstruction, aiming to create durable replacement soft tissue. The study, led by Dr. J. Peter Rubin, may provide a safer option for breast cancer patients, avoiding invasive surgery and potential risks.
Researchers have unraveled the evolution of the csd gene in honey bees, which determines gender. The study's findings could aid in designing better breeding strategies to avoid sterile males.
Research found that healthcare professionals are hesitant to report child physical abuse due to fear of misidentification and confrontation with families. The study suggests that education, training, and support are needed to address this issue and improve reporting rates.
Researchers at UGA discovered a bacterial gene switch that regulates the conversion of sulfur compounds in ocean water to atmospheric emissions, impacting global warming. This breakthrough could help understand the biology and ecology of this process and its practical applications.
A recent study has identified a new genetic link to Crohn's disease, revealing that mutations in the IL-23 receptor gene are strongly associated with the condition. The researchers found that one type of mutation provides significant protection, paving the way for more individualized and effective treatments.
