A new study by UNC-CH researchers found that adolescent obesity rates among second- and third-generation immigrants to the US have increased significantly. The study, based on a nationally representative sample of 13,783 adolescents, suggests that less physical activity and a higher-fat diet are likely responsible for this trend.
Scientists have discovered that antibodies can recognize the orientation of amino acids, allowing them to bind only with specific handedness. This ability may be key to developing new, effective pharmaceuticals by identifying and sorting out left- and right-handed molecules.
A new method for clustering data on computers has been developed by Prof. Eytan Domany, enabling the analysis of vast amounts of information without prior knowledge of its structure or categories. The algorithm mimics human intuition and can automatically identify clusters in various types of data.
Scientists have discovered a novel form of vancomycin that may be effective against resistant bacteria. The findings suggest a new way for the drug to bind to bacteria, opening an avenue for developing next-generation antibiotics.
In a Phase II study combining ONYX-015 with standard chemotherapy, nine out of ten patients experienced tumor regressions greater than 50 percent, including two complete responses. Thirty percent of patients treated with ONYX-015 alone showed significant tumor regression.
UCSF researchers report that the osteoporosis prevention drug raloxifene drastically reduces the risk of breast cancer in postmenopausal women without increasing the risk of endometrial or uterine cancer. The study found a 70 percent reduction in breast cancer cases among participants taking raloxifene compared to those receiving placebo.
Seismologists capture detailed images of deep underground processes at mid-ocean ridges, revealing melting rock flows up in a broad zone rather than a narrow plume. This new data represents a major step forward in understanding Earth's crust formation and volcanic activity.
Researchers demonstrate intratumoral delivery of the E1A gene, downregulating HER-2/neu expression and tumor responses. The study shows promise for using E1A gene therapy to treat a broad range of cancers.
Researchers have identified genes that enable plants to produce epoxy and acetylenic fatty acids, key components in the production of polymers and specialty chemicals. This breakthrough could lead to the development of new, high-value products from plant-based raw materials.
Researchers found that bone marrow transplant significantly improves disease-free survival for children with high-risk neuroblastoma. Additionally, follow-up therapy with high doses of retinoic acid shows promising results, with a three-year event-free survival rate of 55% compared to 16% for those treated with consolidation chemothera...
Researchers found that at high temperatures, a phenomenon called the surface barrier slows down columns of dynamic magnetic fields, allowing current to flow along the edge. This discovery throws new light on superconductor properties and may lead to advanced materials with improved properties.
Researchers at Northwestern University Medical School have developed a rapid diagnostic test to detect vancomycin-resistant enterococci (VRE), a growing threat to hospital patients. The new method, called hot-start polymerase chain reaction (PCR), detects VRE in 13 of 15 specimens, allowing for early isolation and treatment.
