A new patented device co-developed by Ohio State University engineers helps scientists separate cells in the laboratory for transplant and cancer research. The device refines existing magnetic cell separation techniques to better measure how well cells are labeled and magnetized.
A team of scientists suggests that meteorites like ALH84001 could have transferred life between Mars and Earth. The analysis of the meteorite's magnetic field supports the hypothesis that meteorites can be an interplanetary delivery system capable of transferring life.
Lawrence J. Marnett's research focuses on identifying functional biochemical differences between COX-1 and COX-2, which play a crucial role in cancer development. The grant will support the development of more specific and effective drugs to prevent and treat cancer.
Researchers have identified a protein called BNC1 that plays a crucial role in sensing light touch, allowing animals to detect gentle stimuli like a mosquito landing on their arm. The study found that knocking out the BNC1 gene greatly reduces the ability to sense light touch, but not completely eliminates it.
The National Institute of Mental Health (NIMH) has named 25 new Outreach Partners for its Constituency Outreach and Education Program, bringing the total number of Partners to 43. These partners will deliver science-based mental health information to the public and healthcare professionals through various outreach programs.
Researchers at Clemson University have developed a new laser imaging system that provides more detailed views of breast tissue than traditional mammograms. The system uses 16 laser points to detect growths not visible on regular mammograms and predict tumor malignancy with high accuracy.
A recent study found that students who effectively manage their time tend to have better grades, regardless of the number of study hours they put in. The research suggests that educators should reevaluate how they assess student efforts and consider changes to promote academic success.
Researchers will follow 1,000 HIV patients over three years to track health, attitudes, and treatment patterns, with a focus on rural areas where barriers hinder efforts to reduce HIV spread and mortality. The study aims to explore the role of coping mechanisms, stress, and social support in HIV transmission and disease progression.
A study found that college students who were liked by their roommates had higher self-esteem, less depression, and fewer physical problems. In contrast, those who were not liked experienced more mental and physical issues, including low self-esteem, depression, and illness.
New analysis reveals Comet LINEAR might have begun coming apart in mid-June, contrary to initial predictions. The comet's erratic behavior and eventual demise thrilled astronomers, who are now studying the data to understand its breakup process.
A study by Alaskan and Canadian researchers found that climate change and commercial fishing negatively affect sockeye salmon runs in Alaska. The research used nitrogen isotope analysis to track salmon populations over 300 years, revealing a link between climate shifts and changes in salmon abundance.
Researchers at UT Southwestern Medical Center found that automated external defibrillators (AEDs) can save the lives of sudden cardiac arrest victims aboard aircraft, with a survival rate of 40% in a two-year study. The smaller, automated device requires less training to use safely and is approved for airline use.
Scientists have identified a molecule called VR-OAC that senses osmotic pressure in vertebrates, including humans. This discovery may provide insight into the biological basis of inner ear function and the sense of touch.
The UCSF Vietnamese Community Health Promotion Project has received a $3.6 million CDC grant to improve breast and cervical cancer screening among Vietnamese women in Santa Clara County. The project aims to address the high rate of cervical cancer in this population, which is five times that of Caucasian women.
The Respiratory Tract Infection Alert, a first national tracking system, provides predictive information via the Internet and a toll-free number to predict RTI season peaks. The system tracks common respiratory tract infections such as bronchitis, sinusitis, and pneumonia.
Jefferson scientists discover that blocking a protein affects collagen gene expression in both normal and scleroderma cells, offering new hope for treating the disease. The findings suggest that therapeutic compounds may be developed to inhibit this pathway and reduce collagen production.
The Commonwealth of Pennsylvania has awarded a $10.5 million grant to co-directors David E. Luzzi and Kambiz Pourrezaei, aiming to remaking the region as 'Nanotech Valley.' The Regional Nanotechnology Center will fund interdisciplinary research and promote collaboration between academia and local industries.
Researchers at Purdue University have developed a novel low-power circuit that can dynamically adjust memory usage to minimize energy consumption. The new design reduces the amount of energy needed to run a computer's memory by up to 62% while maintaining performance levels.
A new study found that watching television news can help people with low education levels understand political candidates better, closing the knowledge gap between less and more educated individuals. In contrast, reading newspapers is more effective for highly educated individuals who already possess a strong grasp of politics.
Researchers at Ohio State University have made a breakthrough discovery that may lead to a new therapy for patients who suffer from heart attacks. The study shows that blood-derived cells called monocytes can create tunnels in damaged heart tissue, which can potentially be used to grow new blood vessels.
Scientists have embarked on a collaborative effort to sequence the Fugu fish genome, offering valuable insights for identifying genes in the human genome. The project aims to utilize the Fugu genome's compact size and minimal 'junk DNA' to facilitate gene discovery.
