A team of scientists from NASA and Max Planck Institute observed the deflection of galactic dust grains by solar radiation, finding that radiation pressure is stronger than solar gravity for certain mass ranges. This phenomenon affects the trajectory of dust particles near the Sun, causing them to move slower and be deflected.
Scientists have detected rotational motion in ion channel gates, which control the flow of sodium and potassium ions. The discovery challenges current models and may aid in developing future treatments for neurological disorders.
The UCSF School of Medicine has received a $3.8 million grant from the Howard Hughes Medical Institute to support biomedical research and recruit top young scientists. The grant will also fund renovations and equipment for older labs, enabling researchers to set up new facilities.
The discovery reveals how the kinesin motor generates motion along microtubule tracks, with a key role played by the neck linker. This understanding could lead to medical therapies targeting kinesin activity in cancer and neurodegenerative diseases.
Researchers have figured out how kinesin motors separate chromosomes, distribute embryonic material, and transport precious cargo in organisms. The discovery reveals a crucial leapfrog motion that allows the motors to move along microtubules, generating force to haul objects up to a thousand times their own size.
Researchers at UNC-CH have successfully repaired a genetic problem causing cystic fibrosis, offering new hope for patients. The technique involves correcting a mutation involving unnecessary information inside a gene, resulting in the production of normal messenger RNA.
The University of Michigan Medical School will receive a four-year, $4 million grant from the Howard Hughes Medical Institute to support its new bioinformatics program. The program aims to educate tomorrow's scholars in this emerging scientific field and develop next-generation bioinformatics tools.
Microorganisms can survive deep underground due to high temperatures, availability of water and chemical nutrients, porosity of the surrounding rock, and flow of fluids. Subsurface scientists have identified these factors to understand how extremophiles colonize environments and potentially shed light on life on other planets.
A recent study by Johns Hopkins Medicine found that thinking of a favorite sexual fantasy can decrease pain perception. The study suggests that counterbalancing pain with a strong positive emotional response, such as those experienced during sexual fantasies, may be a simple and cost-free way to lessen pain in various situations.
The Arctic Oscillation is linked to warmer winters in Scandinavia and Siberia, stratospheric ozone layer thinning, and altered surface winds. This phenomenon could be part of human-induced climate change, according to researchers.
Researchers at Idaho National Laboratory have discovered that microorganisms can break down urea and promote the formation of calcite, trapping radioactive strontium-90. This process could be used to contain contaminant until it decays away, potentially providing a cheaper and safer alternative to surface extraction.
Researchers at UCSF found that reducing a worm's ability to perceive its environment through smell or taste extends its lifespan by more than a third, from two weeks to three or four weeks. This suggests that chemical signals from the environment, possibly pheromones or food smells, influence aging in C. elegans.
A groundbreaking study published in Nature reveals that many coral reef fish spend their life cycle close to home, rather than drifting in the open ocean. This finding has significant implications for marine conservation and fisheries management, as it challenges the prevailing view of larval dispersal.
A nationwide clinical trial showed that Vagus Nerve Stimulation (VNS) improved the condition of 40% of patients with severe treatment-resistant depression, enabling them to return to work and normal activities. The treatment has been compared to electroconvulsive therapy and may have potential as an alternative for some patients.
A recent search using an Arizona-based telescope failed to detect evidence supporting a 13-year-old theory that small comets composed of snow continually bombard the Earth. The researchers found no conclusive evidence for small comets weighing 20-40 tons each, which were predicted to disintegrate in the atmosphere every minute.
