Researchers have identified key genes controlling skeleton development, including Hox10 and Hox11. These paralogous genes orchestrate construction of ribs, spine, and limb bones, with knocking out all forms revealing dramatic effects on development.
A UK study found no overall increased risk of death among women who used oral contraceptives, suggesting a potential lower mortality rate compared to non-users. Smoking was associated with a higher risk of death from all causes, particularly in heavy smokers.
A joint U.S.-Georgian team aims to develop a novel treatment against bacterial pathogens causing salmonella infection. The grant supports phage therapy research to prevent massive outbreaks and address growing antibiotic resistance.
Scientists at Vanderbilt University Medical Center have identified a new compound that activates glucokinase, an enzyme that regulates blood sugar levels. The compound has shown promise in improving insulin secretion and glucose usage in animals with diabetes, paving the way for potential clinical trials.
A gene variant appears to increase the risk of depression following stressful life events, according to a new study. People with the short version of the serotonin transporter gene were more likely to develop depression if they experienced multiple stressful life events.
The WHO 2003-2008 programme focuses on controlling HIV/AIDS, with a goal of 3 million people in developing countries receiving antiretroviral treatment by 2005. The initiative also aims to strengthen health systems and secure political backing for investment.
Researchers found that a specific gene variant interacts with stressful events to predict depression risk, with individuals carrying a short allele more vulnerable to depression after stress. The study's findings suggest new potential treatments and diagnostic techniques for millions of people worldwide affected by depression.
A recent study suggests that reducing the seizure-free interval from 12 to three months does not significantly increase total crashes. The researchers found that seizures-related crashes increased by 11, while deaths due to seizure-related crashes decreased.
A protein called PPAR-alpha is critical to this process, and the liver plays a key role in explaining the high incidence of diabetes and hypertension in obese individuals. The study suggests that understanding how steroids cause side effects may help prevent these disorders.
Researchers from Ames Laboratory aim to create efficient and selective nanocatalysts using mesoporous materials with controlled nanopores. The goal is to improve the selectivity of current mesoporous materials, which often require costly separation techniques.
A long-term study found that patients with leukoaraiosis, a condition characterized by scattered loss of white matter in the brain, were 1.5 times more likely to have a stroke than those without the condition. The risk was even higher for multiple strokes, leading to increased disability.
Researchers argue that improving current cars and environmental rules is more cost-effective than developing hydrogen fuel cells, which require significant investment in infrastructure. Increasing fuel efficiency or raising prices can achieve similar reductions in air pollution and greenhouse gas emissions without the need for new infr...
The team reconstructed a mass map of the galaxy cluster using NASA/ESA Hubble Space Telescope data, tracing dark matter's distribution with respect to galaxies. The study reveals that dark matter clumps together in certain regions, supporting the idea that clusters assemble through the merger of smaller groups.
Research found that salicylic acid in aspirin disrupts the stress system of S. aureus bacteria, reducing its ability to cause infection and adhere to host tissue. This finding offers hope for treating sepsis, a blood poisoning disease responsible for 750,000 US deaths annually.
A team of scientists has discovered that convection may also be occurring in the Irminger Sea east of Greenland, potentially forming deep waters. This finding places additional complexity on the climate system and suggests far-reaching implications for Labrador Sea Water formation.
A landmark study on lemur nutrition by Dr. Jennifer Campbell reveals that lemurs have different dietary requirements, with some eating leaves, fruits, insects, seeds, and nuts. Her research has led to the development of a proper diet for the animals, improving their health and reproductive success.
A study found that 90% of trachoma infections occur in children under 10 years old in Tanzania and The Gambia. The SAFE strategy, which includes surgery, antibiotics, facial cleanliness, and environmental improvements, is key to eliminating trachoma by 2020.
A study found that food diaries were more accurate than questionnaires in measuring fat intake, which could explain why no association was found between increased fat intake and breast cancer risk. However, the results highlight the importance of using reliable dietary assessment methods in nutrition research.
The HOME scientists used various instruments and equipment to track ocean energy and turbulence, finding that the Hawaiian Ridge is a site with vastly increased ocean mixing. They documented undersea internal wave energy enhanced 10 times at the ridge compared to normal open ocean areas.
Dr. Collier's pioneering research has led to significant advances in vaccine design and therapeutic development, with applications in anthrax treatment and cancer therapy.
A 3,360-acre marine protected area has been established off Belize's southeastern coast to safeguard the region's highest priority area for conservation. The area is home to over 25 reef fish species and is a key spawning ground for the endangered whale shark.
Researchers Peter Sasieni and Jack Cuzick argue that starting mammographic screening at age 47 can save more life-years than current guidelines. They claim that the incidence rate of breast cancer is as great in women aged 48-49 years as it is in those aged 50-54 years, making earlier screening a viable option.
