A study by Princeton University and the Institute for Advanced Study suggests that Earth's varying reflections can provide clues about distant, potentially habitable planets. By analyzing changes in light over time, scientists may gain insights into a planet's weather, oceans, or even plant life.
A new study shows that paramedics can effectively treat patients with acute and prolonged seizures using injections of benzodiazepines. Lorazepam was found to be more effective in stopping seizures than diazepam, with 59% of patients responding to the treatment.
Virginia Tech researchers have developed new proton exchange membrane (PEM) polymer nanocomposites that can withstand higher temperatures, making them suitable for more efficient fuel cells. The new materials use hetropolyacids to retain water molecules at higher temperatures, providing a mechanism for conductivity.
Genetic modified organism (GMO) crops can benefit from a 'refugia strategy' that preserves susceptible insect genes. This approach aims to counteract potential insect resistance by allowing certain pests to survive and breed in GMO-free areas.
Researchers at Johns Hopkins University have developed a new antimalarial drug that has passed the first stage of preclinical testing in mice and rats. The carboxyphenyl trioxane compound shows good therapeutic index, safety, and efficacy in treating malaria.
A new test measuring visual field responses to discordant images has provided clues about the brain activity underlying visual consciousness. The researchers found that binocular rivalry occurs at a lower level in the visual cortex, specifically in the primary visual cortex.
Researchers are investigating the predation habits of Nanomia cara, a gelatinous midwater animal, in the Gulf of Maine. The study aims to determine how this species affects food availability for young cod and other commercially important fishes.
Virginia Tech researchers have made a breakthrough in creating polymers that can be reversed using heat, opening up new possibilities for thermoplastic elastomers (TPE) and novel adhesives. The team synthesized nano-phase separated polystyrene and polyisoprene based materials containing reversible linkages.
A new technology, InStreem™, has been successfully demonstrated at the George DeRuyter Dairy in Washington state, reducing odors and solids in waste lagoons. The system converts existing lagoons into extended aeration systems, establishing conditions favorable for both aerobic and anaerobic degradation of wastes.
Virginia Tech biochemist White identifies 200 genes responsible for coenzyme formation in Methanococcus jannaschi, an ancient Archaea bacteria. The discovery sheds new light on the evolution of metabolic processes in these unique organisms.
Chemists are using statistical design of experiments and parallel reactors to improve the creation of polymers. This approach enables the efficient production of novel elastomers by determining the optimal reaction conditions. By doing so, researchers can generate predictive models and discover new materials.
A study found that consuming five or ten grams of ground flaxseed daily for seven weeks reduced blood levels of certain estrogens associated with an increased risk of breast cancer. The researchers believe that lignans in flaxseed may lower estrogen levels by inhibiting enzymes involved in estrogen synthesis.
Rensselaer Polytechnic Institute graduates Dean Nieusma and Elizabeth Press have been awarded prestigious Fulbright student grants. Nieusma will conduct an ethnographic study on technology design practices in Sri Lanka, while Press will work with at-risk students in the Dominican Republic through her 'Video Connections' project.
Research reveals heritability plays a major role in determining the age of menopause, with significant implications for women delaying childbirth beyond 30. Genetic analysis suggests that a woman's store of eggs declines throughout life, triggering menopause.
Researchers found a black tea polyphenol compound, TF-2, that kills virtually all cancer cells while leaving normal cells intact. The compound also suppresses a gene associated with colon cancer and may be the reason for the chemopreventive activity of black tea extracts.
Dr. Peter Makovicky's discovery sheds new light on the feeding behavior of ornithomimid dinosaurs, revealing a possible adaptation to filter-feed tiny invertebrates and particles from water and sediment. The find is significant as it provides evidence for the unique beak structure found in two well-preserved specimens.
Research in aplastic anemia reveals crucial insights into immune system dysfunction and potential therapeutic targets. Patients with aplastic anemia display impaired T cell responses, indicating a critical link between immunodeficiency and disease progression.
Researchers have discovered a potent anti-cavity agent in Brazilian honeybees' propolis, which cut the cavity rate in rats by about 60 percent. The team is now testing the substance on human volunteers to determine its efficacy as a potential preventative measure for cavities.
A team of researchers led by Louis J. Ptacek identified a novel gene, mass1, responsible for audiogenic reflex epilepsy in the Frings mouse strain. The gene was found to be mutated in mice with spontaneous seizures triggered by loud noises.
Scientists at the University of Illinois have developed a novel laser technique to study chromatin movement in living cells. By measuring the movement of DNA, they found evidence of subdiffusion within the cell nucleus, suggesting that molecular crowding is crucial for life.
Scientists have developed a new block copolymer structure that increases the conductive monomer without weakening the polymer strength. This breakthrough enables better proton conductivity and lower water uptake compared to random copolymers of similar composition.
A new DNA-based cancer treatment has shown promise by targeting and eliminating tumor cells. Researchers have discovered that DNA vaccination can place tumors in a state of immune activation, making them more susceptible to attack.
UCLA researchers have discovered a unique gene modification that may be the cause of certain types of lymphoma. The discovery, which involves DNA methylation, could lead to new treatments for these types of cancer.
Scientists studying Jupiter's moons using laboratory simulations and spacecraft data reveal unique chemical reactions driven by high-energy electrons and ions. The findings support the presence of frozen brine on Europa's surface and provide insights into radiation-induced processes in outer space.
A new study finds that administering benzodiazepines to patients with status epilepticus en route to the hospital can significantly reduce seizures. Lorazepam was found to be at least as effective, if not more so, than diazepam in treating seizures.
A study published by the American Chemical Society found that consuming three-fourths cup of tomato sauce daily for three weeks reduced DNA damage and PSA levels in 24 black volunteers with newly diagnosed prostate cancer. This suggests that eating extra tomato sauce may be beneficial to those at high risk for prostate cancer.
