Astronomers have identified a new type of star in a compact binary system, exhibiting properties similar to brown dwarf stars. The discovery sheds light on the formation and evolution of extra-solar planets, which are often found close to their host stars.
Researchers at UNC used antisense oligonucleotides to target RNA splicing pathways implicated in cancer and genetic diseases. The technique successfully sensitized cancer cells to chemotherapy and radiation, offering a potential breakthrough for targeted therapy.
Professor William Johnson seeks to understand ancient reading habits, focusing on the social context rather than individual acts of reading. His research aims to shed light on why the ancients preferred reading aloud and its cultural significance.
A study of over 40,000 individuals reveals that non-physician clinicians are increasingly providing preventive services and working with physicians to care for patients. The findings highlight the importance of effective communication and coordination between physician and non-physician clinicians to improve care quality.
A team of Colorado researchers has discovered a large population of 'proplyd' objects in the Carina Nebula, located 7,300 light-years from Earth. The newly found proplyds are roughly 100 times the diameter of our solar system and are puzzling for several reasons.
Researchers have discovered the first active miniature inverted repeat transposable elements (MITEs) in rice, providing insights into genetic diversity and potential applications in crop improvement. The findings also highlight the importance of active transposable elements in generating tagged mutations that can reveal gene function.
A new study suggests that black holes can form before galaxies, with massive black holes found in even the smallest active galaxies. The research, led by Marianne Vestergaard at Ohio State University, uses a method to estimate the mass of distant black holes and finds that they are often more massive than previously thought.
The American Thoracic Society has named two Department of Veterans Affairs clinician-scientists, Rabih I. Bechara and Pierre P. Massion, as the first recipients of its Research Career Development Award. The award will provide $20,000 per year for three years to support their research on respiratory diseases.
The research aims to identify key players in the innate immune system and study gene expression patterns triggered by microbial invasion. The grant will support a systems biology approach to understand how the system behaves as a whole, ultimately informing novel hypotheses.
Scientists propose that a massive thermal burp could have briefly insulated the moon's core, allowing it to cool quickly and produce a magnetic field. This theory also explains the uneven distribution of metal-rich volcanic rock on the moon's surface.
A study found that near-daily intake of alcohol is associated with the lowest risk of heart attacks in men. Regular consumption at least three to four days per week was linked to a reduced risk of coronary heart disease.
A combination of DEET, permethrin, and pyridostigmine bromide may have inadvertently damaged Gulf War soldiers' testes and sperm production, according to a Duke University Medical Center study. The chemicals caused extensive cell degeneration and cell death in rats, leading to severe testicular damage.
A new study published in the New England Journal of Medicine found that frequent light-to-moderate drinking reduces heart disease risk in men. Men who consumed alcohol three or four days a week had approximately 2/3 the risk of heart attack compared to those who drank less than once a week.
The Ohio State team is contributing to NASA's ICESat mission, which aims to map the Earth's ice sheets using a radar-like system. The team has developed lidar mapping software that will help calibrate the satellite's lidar system and create accurate maps of ice sheet extent.
A study found that individuals who received poor scores on an intelligence test watched television longer and were less likely to look away from the screen. In contrast, those who performed well watched for a shorter duration. Television use may serve as a distraction from negative self-feelings.
Researchers found the first active 'miniature inverted-repeat transposable element' (MITE) in rice, which can move DNA to different places in the genome. The discovery provides new insights into how genomes change and what role transposons play in promoting plant diversity.
A University of Alberta scientist warns that polar bears are in danger of extinction due to the rapid melting of Arctic ice. The world's largest terrestrial carnivores rely on sea ice for survival, and climate change is accelerating its disappearance.
Researchers found that providing reliable warning cues enhances vigilance performance, maintaining attention and efficiency over time. The study's results have practical implications for designing operational cueing systems to reduce brain strain and improve safety in various applications.
The Sloan Digital Sky Survey has identified dozens of dim binary star systems throughout the Milky Way, which are older and cooler than previously thought. The study finds that these close-binary systems have a low rate of mass transfer from the red dwarf to the white dwarf, making them less likely targets for many telescopes.
A community-based care model has been shown to be effective in treating multidrug-resistant tuberculosis (MDR-TB) in resource-poor nations. The study found that 83% of patients who completed at least four months of therapy had probable cures, exceeding the best reported U.S. cure rate.
