This finding has important implications for various astronomical data calculations and theories, including star formation and cosmology.
Researchers have found an antidepressant, clorgyline, can blunt and reverse muscle enlargement and weakened pumping function associated with heart failure. The drug blocks the action of enzyme monoamine oxidase-A and stops its breakdown of a key neurohormone, norepinephrine.
Researchers have developed a vaccine that appears to reduce leukemia cells in some chronic myeloid leukemia (CML) patients taking the drug Gleevec. The study found significant reductions in residual cancer cells and complete remission in seven patients.
Researchers sequenced over 100 kidney cancer samples, identifying mutations in genes controlling gene expression and chromatin structure. The study reveals genetic complexity in ccRCC, providing insights into diagnosis and treatment options.
A new study predicts that the H1N1 virus can spread quickly on planes, particularly in crowded economy classes. Researchers used mathematical modeling to estimate potential infections during long-haul flights and found that two to five infections could occur on a five-hour flight.
Neuroscientists at MIT have developed a powerful new class of tools that can reversibly shut down brain activity using different colors of light.
