Scientists have uncovered the molecular structure of cartilage's collagen fibrils, a key factor in osteoarthritis. The discovery could lead to treatments that prevent fibril deterioration and ultimately alleviate joint pain.
A recent USGS study compared nine different formulations and confirmed that most still have toxic additives, but some de-icers may be safer for the environment than those used in the 1990s.
Researchers at Penn School of Medicine have shown a 51% reduction in low-density lipoprotein (LDL) cholesterol levels in patients with homozygous familial hypercholesterolemia. The new therapy, which targets the microsomal triglyceride transfer protein, also decreased total cholesterol and triglyceride levels.
Researchers found DNA methylation in normal-appearing areas of the breast near tumors, suggesting a potential marker for early cancer detection. Abnormal methylation levels were also identified in three other genes, which may help estimate a woman's risk of cancer recurrence.
Research reveals that PMR1 enzyme forms temporary shelters in stressed cells to protect mRNA, allowing protein production to resume when stress ends. This protective mechanism may help cancer cells evade cancer therapies.
A newly identified wheat gene produces proteins that bind to the stomach lining of Hessian fly larvae, causing them to starve. The gene's role in creating resistance to Hessian flies was a surprise to researchers, who found that it triggers a localized defense response that reduces energy costs for the plant.
A study found that possessing power impairs an individual's ability to adjust to another person's perspective and interpret emotions. Researchers discovered that individuals with high power levels are more likely to prioritize their own viewpoints, leading to decreased empathy.
A new study suggests that delaying the use of nevirapine-containing antiretroviral therapy (ART) for at least six months after labor can improve treatment outcomes among HIV-infected women. The study found that women who started ART within six months of giving birth had a higher rate of treatment failure compared to those who delayed t...
A new study from Michigan Medicine finds significant variation in Medicare Part D prescription drug plan costs across states, even with lowest-cost plans. Seniors may face costs differing by thousands of dollars for the same medications, and within a state, the difference can be $10,000 or more.
The number of US high school students taking physics has increased to a record high, with more than 30% of seniors enrolling in physics classes. Physics bachelor's degree recipients are also on the rise, with a 31% increase since 2000 and a significantly higher likelihood of pursuing advanced degrees.
A national study by Duke University researchers found that people with psychiatric disabilities are less likely to receive monetary awards or job-related benefits in court cases. They also report feeling less treated fairly and receiving less respect during the legal process compared to those with physical disabilities.
A team from the University of Cambridge and the Pacific Northwest National Laboratory reported that minerals intended to entrap nuclear waste may break down within 1,400 years due to radiation. The study used NMR to show that plutonium incorporation into mineral zircon rapidly degrades its crystal structure.
A new study finds that UK and US Arab activists define themselves as members of multiple communities and express attachment to their countries of origin. They also value the rights and security offered by their adopted lands and advocate for mutual accommodation and respect between different groups.
A pivotal Phase III trial demonstrated Nexavar's efficacy and clinical benefit in patients with advanced renal cell carcinoma. The study showed a median progression-free survival of 5.5 months for patients receiving Nexavar, compared to 2.8 months for those on placebo.
Anthony Rosenzweig and European coordinator Timothy Aitman will lead a five-year, $6 million Leducq Foundation grant to investigate the intersection of heart failure and metabolic disease. The team will focus on understanding common molecular mechanisms contributing to both conditions.
Researchers have identified a unique pattern of microRNAs in pancreatic tumor tissue, suggesting a new way to diagnose and treat the disease. The findings may lead to more effective early detection and treatment of pancreatic cancer.
Researchers discovered that neutrophils can form web-like structures called NETs outside cells, composed of nucleic acid and enzymes that catch bacteria and kill them. This process is equally effective as devouring bacteria, showcasing the neutrophil's role in defense even after death.
A new automated system installs raised pavement markers (RPMs) along lane stripes while in motion, reducing risk to workers and drivers. The system is less labor-intensive, faster, and safer than manual placement, using less fuel and causing less wear on equipment.
Researchers found that a common diabetes drug prevents memory and learning problems caused by whole-brain radiation treatments in animal studies. The study suggests the drug may improve the quality of life for cancer patients receiving radiation therapy.
Researchers found that starting HIV treatment at least six months after a single dose of nevirapine during labor improves response rates. Women who started treatment sooner had reduced effectiveness of ART, while those delayed had comparable outcomes to placebo group.
A study by the University of Bristol revealed that children's packed lunches are often lacking in essential nutrients like potassium and zinc. In contrast, school meals tend to provide higher intakes of protein, vitamins, and minerals, as well as lower sugar and saturated fat content.
Researchers found that the Pacific and Indian oceans receive twice as much nitrogen fixing as previously thought, indicating a more stable global picture of nitrogen fixation than initially assumed. This discovery suggests that major fluctuations in ocean nitrogen are unlikely and may be mitigated by climate change.
Astronomers have discovered a powerful outburst from the giant black hole at the Milky Way's center using NASA's Chandra X-ray Observatory. The light echo revealed by the X-ray echo was about 1,000 times brighter and lasted well over 1,000 times longer than recent outbursts.
Research by Dr. Piers Steel reveals that perfectionism is not the root cause of procrastination, but rather a lack of confidence and expectancy. The study estimates that 15-20% of the population are procrastinators, with costs extending beyond poor work performance to financial and health implications. Steel's Temporal Motivational The...
Cambridge scientists have discovered that differences between embryonic cells appear earlier than previously thought, before the fourth cleavage of the embryo. The study suggests that manipulating epigenetic information in histone H3 can influence cell fate determination.
A University of Alberta study shows that beaver dams create suitable breeding habitats for frogs and toads, with approximately 5,000 species recorded at 54 beaver ponds. The beavers' presence enhances the development and growth rates of frog and toad larvae.
The International Association of National Public Health Institutes (IANPHI) will strengthen public health infrastructure globally, focusing on low-resource countries. The grant enables IANPHI to establish a peer-assistance model for developing national public health institutes.
Inadequate treatment of mental illness and addiction in the community contributes to rising incarceration rates. Effective therapy like mental health services and substance abuse programs can reduce recidivism. Physicians are urged to campaign for humane treatment alternatives.
Researchers used Hubble Space Telescope to reveal a large elliptical galaxy with hundreds of globular clusters at an unprecedented 1 billion light-year distance. The discovery provides insights into the age, origin, and evolution of these clusters.
Researchers at Bradley Hospital and Brown Medical School found that individuals with BDD who have weight concerns experience more overall areas of body image concern, poorer social functioning, and higher levels of comorbidity. Weight-related preoccupations in BDD sufferers are associated with even higher levels of distress and impairm...
