Scientists have improved understanding of TGF-beta's regulation in Marfan syndrome by studying mice with genetic mutations. They found that blocking TGF-beta activity during development may prevent features of the disorder, including emphysema and aortic rupture.
Marine geologists will study Kick'em Jenny, a highly active volcano in the Caribbean, using advanced instrumentation and technologies. The two-week research cruise will investigate the volcano's acoustic signals, biological communities, and geological features.
Researchers discovered that a gene mutation in mice leads to severe glaucoma by disrupting ocular drainage structures. Administering L-DOPA to pregnant mice with the mutation improved pup outcomes, suggesting potential therapeutic benefits.
The American Chemical Society's editor-in-chief, Jacobs, has won a national award for her efforts to encourage women in chemistry careers. Despite complex issues such as family life and career demands, Jacobs continues to advocate for women in the field through publications and public speaking.
Columbia University's Center for Community Health Partnerships will explore ways to improve health in minority populations through community-based research and collaborations. Researchers will develop a four-year cultural competency curriculum and support training programs for medical students and minority investigators.
Researchers at The Wistar Institute have discovered a family of molecular complexes involved in the repression of extensive sets of tissue-specific genes. These complexes share two core subunits, including histone deacetylase and BHC110, which operate as co-repressors to maintain gene silencing.
A new method, KL clustering, has been identified as more effective than hierarchical clustering in separating gene expression data into dense clusters. The approach uses a novel measure of similarity to create well-separated clusters, offering insights into gene-gene interactions and biological processes.
A study of 289 teenagers found that cardiovascular fitness and lower body fat are independently associated with greater insulin sensitivity. Improving fitness or reducing body fat could protect high-risk children from developing insulin resistance, a precursor to diabetes.
The American Institute of Physics and the Acoustical Society of America offer science writing awards in acoustics. The most recent winners include "Snap, Crackle and Pop" by Bennett Daviss and "Acoustic Surgery" by Shahram Vaezy et al.
A Dartmouth study found that better transportation decisions, such as driving fuel-efficient cars, could save more energy than recycling plastic and aluminum. Researchers used life-cycle analysis to measure the environmental benefits of different activities.
Researchers found that preschoolers with depression exhibit symptoms similar to those in older children and adults, including anhedonia, sadness, and low energy. The study also highlighted the importance of identifying and treating depression in young children to prevent impairment of normal development.
A study by the American Heart Association suggests that women approaching menopause should take steps to lower their heart disease risk. Researchers analyzed data from over 1,300 perimenopausal women and found that many would become eligible for cholesterol-lowering therapy after age 55 if current risk factors are not modified.
The Office of Naval Research will host a venture initiative called the 'wargame,' which aims to improve the technology transition process. The game will examine venture capital decision-making and mechanisms for engaging the venture capital community.
Researchers at UC Davis found that organic and sustainably-grown fruits and vegetables contain higher levels of polyphenolics, a type of natural chemical with potential health benefits. The study suggests that the absence of pesticides and fertilizers in sustainable farming practices may lead to increased production of these chemicals.
A new study identifies molecular predictors of breast cancer metastasis, including matriptase and HAI-1. The research may lead to a targeted way to treat cancers at risk of spreading, saving women from unnecessary chemotherapy.
Research finds that lower socioeconomic status groups take longer to recover from stress-induced blood pressure increases, leading to heightened disease risk. The study suggests that adapting quickly to stress is crucial in reducing biological damage.
Researchers at St. Jude Children's Research Hospital found that an anti-flu-virus drug can protect against pneumonia by blocking the activity of flu virus enzyme neuraminidase. This protection reduces illness and incidence of death from subsequent infection by Streptococcus pneumoniae bacteria.
A study found that veterans with diabetes spent a significant amount of time in hospital and outpatient services, with nearly 40% hospitalized one or more times per year. The patients faced a high risk of dying within a given year, with approximately 6% at risk of mortality.
Researchers at Columbia University have found that astrocytes can degrade beta-amyloid proteins, a key component of Alzheimer's plaques, suggesting potential therapeutic targets for the disease. The study suggests activating astrocyte activity may be beneficial in reducing plaque buildup and improving treatment outcomes.
Researchers genetically altered a protein to prevent phosphorylation, resulting in mice that could learn but not remember spatial locations. This discovery sheds light on the role of neuronal plasticity in learning and memory.
David M. Holtzman and Ashley I. Bush have been awarded the 2003 Potamkin Prize for their work on amyloid accumulation and oxidation in Alzheimer's disease. Their research has provided essential basic foundation for understanding how to treat the pathology related to amyloid accumulation.
A study found a previously unknown abrupt shift in climatic conditions around AD 700 in the Canadian prairies and 500 years later in US prairies. Persistent changes in jet stream shape and storm tracks are believed to cause such patterns.
A recent study by Ohio State University researchers found that nearly three-quarters of hospitalized patients with anxiety received treatment, but symptoms were documented on less than half of their charts. The study highlights the need for systematic evaluation and objective measures to address anxiety management in healthcare.
A study of 4,764 Chinese men found that cigarette smoking is associated with a 60% higher risk of erectile dysfunction. The risk increased with the number of cigarettes smoked daily, highlighting the negative impact of smoking on male sex life.
Researchers found an inverse relationship between upper leg length and diabetes, with shorter legs associated with higher risk. White women and Mexican-American women showed increased likelihood of diabetes for each centimeter less of ULL.
