The Rosalinde and Arthur Gilbert Foundation awards $75,000 grants to five early-career scientists studying the earliest brain changes suggesting Alzheimer's disease. The recipients aim to accelerate development of diagnostic, preventative interventions, and treatments.
A new calculation method determines an individual's 'Maximum Weight Limit' based on height and weight, closely matching BMI recommendations. The simple formula allows for easy calculation and remembering of a single, safe weight limit.
A new rabies vaccine has shown to induce a rapid and efficient immune response in mice and non-human primates, potentially reducing the six-shot post-exposure regimen to just one inoculation. The experimental vaccine lacks a key gene called the matrix (M) gene, inhibiting the virus from completing its life cycle.
Researchers studied 6,257 adult twins and found that those who started drinking early had a greater genetic risk for alcohol dependence. The younger an individual was at first drink, the more prominent the role played by genetic factors in developing severe problems.
A small study of 101 patients found that a one-minute eye movement exam performed at the bedside worked better than an MRI to distinguish new strokes from other less serious disorders. The quick and low-cost test caught more strokes than the current gold standard, suggesting a way to improve care and avoid high costs.
Three medications effective in reducing breast cancer risk also have serious side effects, according to a new study. Tamoxifen, raloxifene, and tibolone reduce invasive breast cancer incidence but vary in their adverse effect profiles.
Researchers at Johns Hopkins School of Medicine discovered that the antioxidant protein Prdx1 controls the activity of GDE2, a critical protein for spinal cord neuron development. The study found that Prdx1 breaks a chemical bond between amino acids in GDE2, activating it to promote motor neuron differentiation.
Interaction between education and a polymorphism of the reward gene contribute to severe alcoholism among Mexican Americans. Researchers found that individuals with less than or up to 12 years of education are at high risk for severe alcoholism when combined with the OPRM1 A/A genotype.
A new study found that completed and attempted suicides occur at greater rates in rural communities with higher bar densities. Completed suicide rates were lower among blacks and Hispanics, but higher among low-income, older whites living in rural areas.
Research found that IL-1 gene polymorphisms are associated with alcohol dependence in Spanish Caucasian males, particularly those with a certain haplotype. The study suggests a protective effect of this haplotype on better outcomes, highlighting the complex role of genetic factors in AD.
Tropical Storm Marty is moving at a slow pace through the Eastern Pacific Ocean with maximum sustained winds near 40 mph. The storm's fate lies in its encounter with cooler waters and drier air, which will weaken it over the weekend.
A new study found that people who start drinking at an early age are more likely to develop alcohol dependence. The study suggests that genetic factors play a significant role in the development of AD symptoms, particularly in those who begin drinking before age 15.
A team of researchers developed an intelligent surveillance system to detect incorrect behavior by drivers and pedestrians crossing pedestrian crossings. The system, based on multi-agent artificial intelligence, can identify abnormal movements and potentially penalize such behaviors.
A team of Princeton and Rice University researchers has developed a new method to identify nitric oxide using lasers and sensors, making it possible for large-scale deployment. The device can detect tiny amounts of the gas in the air or human breath, monitoring pollution and detecting disease such as asthma.
Scientists have created an implantable device that utilizes magnetism to control the release of medication, allowing for precise and repeatable dosing. The device uses nanoparticles that heat up when exposed to a magnetic field, causing the drug to be released into the body.
Postmenopausal women can improve cardiovascular fitness and reduce risk factors for chronic diseases through regular, vigorous exercise. Studies show that even less strenuous aerobic exercise produces benefits, and women's metabolism changes after menopause affect glucose clearance from the blood.
Typhoon Choi-Wan is expected to bring hurricane-force winds and flooding rains to Japan this weekend. The storm's high thunderstorms have reached the tropopause, resulting in extremely heavy rainfall for the area underneath.
Researchers in Australia have developed the first efficient diamond Raman laser, achieving an efficiency of 63.5%, comparable to existing lasers built with other materials. This technology has potential applications in defense technologies, trace gas detectors, medical devices, and satellite mapping.
Researchers found that HIV can mutate its outer proteins to disguise itself from neutralizing antibodies, allowing it to escape the immune system. In two patients, viruses mutated parts of their outer proteins, interfering with antibody attack or targeting a different protein.
A new drug-delivery system using nanoparticles encapsulating nitric oxide or prescription drugs could significantly lessen side effects associated with oral erectile dysfunction medications. The treatment showed improved erectile function in rats and held promise for safer and more effective ED therapy for millions of men.
Researchers at K-State will use a cyber network to study the tallgrass prairie and respond to global warming. The project aims to integrate data from Konza Prairie and other regional institutions to improve ecological forecasting and education.
Researchers found that elephants use two pathways to 'hear' ground-borne vocalizations: somatosensory pathway through feet and trunks, and bone conduction pathway through toenails. This allows them to understand seismic communication over long distances.
A recent study by University of California, Davis, researchers used 'bugs in boxes' to investigate the variability of invasive species' spread. The results suggest that predicting the course of an invasion may be more challenging than previously thought.
Mathematicians at the University of Leeds propose that black holes are directly responsible for producing gamma ray bursts, contradicting the orthodox model. The theory suggests that rotating black holes can devour nearby stars, creating long-lasting jets of plasma that produce the high-energy radiation.
The new program in international research ethics at IUPUI combines coursework and a practicum experience in Kenya to equip students with expertise in bioethics. The IU-Moi Academic Research Ethics Partnership aims to build valuable bioethics capacity globally, starting with partnerships in Kenya.
