Researchers at Penn State investigated alternative diesel fuel DME, which burns smokeless and produces fewer particulates. The team found that DME can mix completely with diesel fuel but its viscosity may be a key property in developing these fuels.
Researchers at INEEL have developed an energy-efficient process to produce alkylate, a high-octane gasoline blend with low environmental pollutants. The new method uses a solid acid catalyst and supercritical fluid solvent to regenerate the deactivated catalyst, increasing its lifespan by 20 times.
A genome-wide study of 308 long-lived individuals revealed a significant correlation between allele sharing on chromosome 4 and longevity. This suggests that the region may contain genes influencing human lifespan, with potential applications in preventing age-associated diseases such as heart disease and Alzheimer's disease.
Researchers at Northwestern University determine the molecular structure of a metallochaperone (CCS) bound to its target protein (SOD), providing new insight into a metal transfer mechanism and shedding light on diseases related to copper and oxidative stress.
Virginia Tech researchers are developing methodology to relate membrane performance to intrinsic polymer properties of microphase separation, water absorption, and proton conductivity. The goal is to produce PEMS that perform well in a wide range of fuel cell environments.
Virginia Tech researchers have developed ultra-thin heat protective coatings for rockets and microelectronics by studying hybrid organic/inorganic molecules. The coatings, which are less than two nanometers thick, offer improved fuel efficiency and weight reduction in space applications.
A study found that switching from a brand-name to a generic epilepsy medication, such as phenytoin, can lead to toxic side effects or loss of seizure control. The variation in the generic formulation can result in a significant decrease in the drug's effectiveness.
Researchers at Michigan State University are developing biocomposites using plant-based materials and sustainable plastic alternatives. These innovative materials have the potential to reduce environmental impact, cost, and production energy while maintaining performance and competitiveness.
Scientists have solved the three-dimensional molecular structure of matriptase, a newly identified serine protease target for breast and prostate cancer drug development. This structural information is expected to facilitate the design of drugs that block or exploit the activity of matriptase and related proteases.
Walter Munk, a leading figure in physical oceanography, is being honored with the inaugural Prince Albert I Medal for his decades-long research on ocean currents, tides, and climate change. His work has significantly improved our understanding of the oceans and their impact on global warming.
A new study found that estrogen patches can improve attention and memory skills in women with Alzheimer's disease. The research used estradiol, a type of estrogen shown to have an effect on the brain, and found significant improvements in attention and memory tests.
A 24-week study found consistent benefits of ARICEPT in patient function, cognition, behavior, and activities of daily living. The medication showed statistically significant overall improvement vs. placebo in behavioral disturbances associated with Alzheimer's disease.
Researchers will use shake tables, centrifuges, and tsunami wave tanks from desktop workstations to conduct experiments. The virtual laboratory, NEESgrid, will connect researchers and facilities across the US, fostering collaboration and accelerating seismic design and hazard mitigation.
The National Science Foundation (NSF) has funded a virtual collaborative research network called NEESgrid. This initiative aims to improve seismic design and hazard mitigation by providing researchers with access to cutting-edge computational tools and experimental equipment, enabling them to share data and resources.
A new study by University of Washington economists found that wives tend to cut back on spending after their husbands retire, indicating a shift in household bargaining power. This difference is attributed to the fact that wives are typically younger and live longer than husbands, leading them to prioritize saving over consumption.
Researchers found that nepetalactone in catnip is about ten times more effective at repelling mosquitoes than DEET. The compound can be used as an alternative to commercial insect repellents with lower concentrations required, making it a promising discovery for pest control.
A study found that pacemakers and ICDs can be infected with Staphylococcus aureus bacteremia without obvious signs, highlighting the need for accurate documentation and removal of devices to prevent serious illness and death. The researchers concluded that removing cardiac devices is essential for patients who develop staph infection.
Researchers identified a region on Chromosome 4 containing genes that contribute to exceptional longevity. This discovery could lead to the development of drugs that mimic centenarians' genetic characteristics, promoting healthy aging.
