Researchers found a significant reduction in breast cancer risk among women taking statins and non-statin lipid-lowering drugs. The study analyzed data from over 7,500 older white women and found a 60-70% lower risk of developing breast cancer.
The study found that mortality rates are significantly lower for patients with a vascular surgeon performing the operation. High-volume surgeons and hospitals resulted in better outcomes, suggesting that experience counts when it comes to treating aortic aneurysms.
Researchers uncover two neighboring genes, Rsl1 and Rsl2, that repress male-specific liver gene expression in female mice. This discovery sheds light on the genetic basis for gender differences in liver function, revealing a complex interplay between multiple genes.
Researchers have developed nanoscale helical 'nanosprings' from zinc oxide that exhibit piezoelectric and electrostatic polarization properties. These structures could be used as sensors to detect small fluid flows, strain forces, and air flows, and as actuators in micro-systems. The new materials also display unusual electrostatic pol...
The NIH has launched a $200 million grant initiative to tackle 14 grand challenges in global health, including creating effective vaccines, controlling insect-borne diseases, and improving nutrition. The program aims to engage creative minds globally to develop practical solutions to pressing health issues.
UCSD researchers have developed a new estimator that outperforms the historic Good-Turing formula under all conditions. The new estimator, called attenuation, evaluates the highest possible ratio between the probability assigned to each symbol in a sequence by any distribution and the corresponding probability assigned by the estimator.
Stevens Institute of Technology has been awarded the Best Online University by the Sloan Foundation, a prestigious recognition for its high-quality online programs. With over 2,250 graduate enrollments in online courses and a revenue of nearly $4 million from its online students, Stevens demonstrates its leadership in online education.
Researchers at Rice University have developed a quantum model to predict nanophotonic behavior, making it easier to design new optical materials and devices. The study shows that plasmons in nanoparticles hybridize with each other, allowing for the prediction of properties in complex metallic nanostructures.
Researchers at Carnegie Institution's Geophysical Laboratory have created a super-hard form of graphite that can rival diamond in strength. The new material was made by subjecting graphite to extreme pressures and studying its atomic structure using high-intensity X-rays.
A multi-center study led by Fox Chase Cancer Center oncologist aims to develop an interactive internet-based tool to assess patient values and information needs, providing education on cancer treatment and communication skills training. The goal is to improve doctor-patient communication and patient satisfaction.
A team of researchers led by Dr. Sharyn Endow at Duke University Medical Center has discovered the power stroke that drives molecular motors, which transport nutrients around cells or herd chromosomes during cell division. This breakthrough could help understand diseases like Down's syndrome and prevent them.
Researchers found that ozone reduces soil carbon formation, a key process for storing organic matter. The study suggests forests may be less effective at cleaning the air of excess carbon dioxide when ozone levels are high.
The Lancet editorial questions the qualifications of key health officials in Iraq, while noting progress in hospital funding. The article warns that donors must prioritize the health and security of all Iraqi people before it's too late.
High rates of uninsured Hispanics and unstable coverage put them at risk for preventable health problems. One quarter of Hispanics aged 50-64 went without needed care due to costs.
Research on blue tits found that extra-pair copulations with distant males lead to more heterozygous offspring, resulting in improved survival and reproductive success. This study suggests that females can benefit from promiscuity by increasing the genetic quality of their progeny.
A multicentre trial involving 351 patients found that anaemia treatment with epoetin beta did not improve cancer control or survival rates. Instead, patients receiving epoetin beta had a 60% better chance of progression-free survival compared to those given placebo.
A recent study found that patients with a genetic subtype of diabetes have a significantly greater response to sulphonylurea drugs compared to those without a defined cause. This discovery highlights the importance of individualizing treatment for patients with type 2 diabetes, depending on their underlying cause.
Conotoxins have extraordinary promise for developing powerful new drugs, including treatments for pain, cancer, epilepsy, and depression. However, habitat loss and uncontrolled exploitation threaten the extinction of cone snail species, which are a valuable source of these medicines.
Fossilized ghost crabs, up to 110,000 years-old, have been found on area beaches in central Florida. The rare discovery suggests that beach erosion, possibly caused by the construction of Port Canaveral, has exposed fossils that were previously hidden by dunes.
Georgetown University Medical Center has received a $6.5 million NIH grant to develop an innovative medical surveillance system that connects DC emergency rooms during crises. The system, known as Project Sentinel Collaboratory, will utilize the InSight real-time data repository and analyze de-identified medical information, weather, t...
Patients with achalasia often experience impeded digestion due to reduced muscle contraction and sphincter relaxation. Research finds that nerve cell loss may cause constipation in these patients, which persisted even after treatment for achalasia.
Researchers discover PPAR-delta pathway that curbs atherosclerosis development and reduces heart disease by half. The pathway could be used to develop drugs to treat heart disease, currently the number one killer of Americans.
For the first time, a US patient's entire aortic arch has been successfully repaired using this technique. The procedure minimizes complications and allows patients to recover quickly, with a lower risk of death or complications compared to traditional open surgery.
The reconnaissance round is a novel device that allows infantry soldiers to see past obstacles from a vertical perspective. It transmits images of nearby terrain back to a laptop computer, enabling soldiers to view the enemy's position in real-time.
A recent study by UF management professors Timothy Judge and Daniel Cable found that being tall comes with significant financial benefits, including higher pay and increased respect at work. The research analyzed data from thousands of participants and showed that every inch of height can add up to thousands of dollars in annual earnings.
The study found substantial survival increases after HAART, with death rates reduced by 50% in 1997 and over 80% by 2001. Injecting drug users had four times higher death rates than those infected through homosexual contact. Earlier diagnosis maximizes treatment gains.
Primary progressive aphasia is a rare form of dementia that affects language abilities while preserving memory. Patients may struggle with word-finding and speaking, but can still recall recent events and maintain complex hobbies.
Researchers at the University of Illinois discovered that the timeless gene is essential for regulating the 24-hour circadian rhythm in mammals. Blocking its functional ability disrupts the clock's activity and leads to an uncoupling effect, where other clock genes are no longer able to function properly.
