Victor Nizet's award-winning research focuses on understanding the production of toxins by group A and B streptococcus in children, shedding light on potential treatments and disease prevention strategies. His work also explores anti-microbial peptides and the mechanism behind group B strep's ability to cause meningitis.
Researchers at Georgetown University Medical Center have discovered a key link between high cholesterol and the development of Alzheimer's disease. Elevated cholesterol levels increase the production of beta amyloid protein, leading to brain cell death and characteristic plaques found in Alzheimer's brains.
The Dartmouth Institute for Security Technology Studies has released a report detailing the technology hurdles faced by cyber crime investigators. The report identifies seven areas of concern, including log analysis, internet protocol tracing, and emerging technologies, to aid in combating cyber attacks.
Researchers have found a key vasodilator degraded in hypertension, leading to potential new treatments that prevent organ damage. A new pathway targeting the kidneys' response to hypertension may help control blood pressure and improve kidney function.
The survey found that in half of the state's school districts, students are opting for a General Equivalency Development (GED) certification instead of passing Regents courses. This trend is serving as a pressure release on the system, with students enrolled in GED programs being reported as transfers and not high school dropouts.
Researchers analyzed gene expression profiles from thousands of lymphoma biopsy samples to identify predictive genes that can predict patient response to treatment and survival rates. The study found that a formula created from 17 key genes could accurately classify patients into four groups with varying five-year survival rates.
The AAAS CEO emphasizes the need for international scientific cooperation to address global challenges. The organization supports unfettered information exchange and travel freedom, highlighting the benefits of science-based diplomacy in bridging political divides.
The record winter weather led to a significant boost in the US economy, with estimated benefits of $21 billion. The mild conditions resulted in lower heating costs, reduced snow-removal expenses, and an increase in construction income.
Researchers at Princeton University have developed a new method for printing ultrasmall patterns in silicon wafers, which could increase transistor density on chips by 100-fold. This breakthrough, called Laser-Assisted Direct Imprint, eliminates the need for costly and time-consuming etching processes.
Researchers at the University of Toronto found that balancing ACE 1 and 2 genes leads to healthy hearts in mice models. The study sheds light on the complex relationship between ACE 1 by-products and cardiovascular disease.
The Society of Nuclear Medicine announced its Image of the Year, showcasing an innovative PET scan for detecting lung cancer in a patient with dermatomyositis. The image also highlights a groundbreaking study on dopamine transporters in mouse brains using ultra-high resolution SPECT.
A study by E. Todd Schroeder and colleagues found that androgen therapy increased muscle mass, strength, and power in older men, improving their ability to perform daily activities. The findings suggest that supplemental androgen therapy might benefit older men prone to losing muscle mass due to sarcopenia.
Researchers develop concentrated colloidal inks that form self-supporting features through a robotic deposition process, allowing for complex shapes and chemical composition variations. The technique enables the creation of fine-scale structures with features as small as 100 microns.
Researchers discovered that fin whales sing low-frequency songs during krill feasts, which could be hampered by human-made noise. The study suggests that human activities like sonar and shipping may interfere with whale communication and reproduction, threatening population recovery.
Research by Dr. Lisa Ellerby at the Buck Institute suggests that calpain, a naturally occurring enzyme, plays a key role in Huntington's disease progression. The study uses post-mortem tissue and cell culture models to show that calpain activation is involved in brain damage.
Dr. Krol will work to engage pediatricians and family practitioners to advocate on behalf of Medicaid dental program improvements. She aims to incorporate oral health education into pediatric residency training programs at Columbia-Presbyterian Medical Center.
A new technique uses ESR to measure distances between atoms in proteins, revealing the overall structure of a molecule. This method is particularly useful for studying larger protein assemblies and membrane-embedded proteins, which are challenging to study using traditional methods.
