Scientists discovered bacteria in deep drill holes on Earth, suggesting similar conditions exist on Mars. The findings imply that microorganisms can thrive in extreme environments, increasing the chances of life existing beyond our planet.
Researchers at OHSU discovered a novel compound called STX that activates a rapid signaling pathway in nerve cells, providing an alternative to estrogen replacement therapy. The new compound shows promise in alleviating menopause symptoms and may be more effective than existing treatments.
Research suggests children who witness violence or hear reports of it exhibit similar levels of behavioral issues as those directly affected, with a small effect observed for personal closeness to victims.
Researchers have demonstrated that carbon nanotube transistors can enhance electrical signals, potentially improving performance of consumer electronic devices. The discovery is based on the principle of stochastic resonance, which claims that noise can improve signal detection.
Stephanie Novak, a doctoral candidate at Washington University in St. Louis, developed a novel model to determine classification of a new species based on skeletal differences. The Archosaurian Morphospecies Concept found that Postosuchus from different locations were part of the same species.
A comprehensive DNA analysis of 744 healthy volunteers has identified 49 distinct genetic variants associated with increased risk of sudden cardiac death. These variants were found in specific ethnic groups and may impact diagnosis and testing for long QT syndrome, particularly among minority patients.
Scientists use Raman spectrometer to analyze minerals, gases and liquids on the sea floor, tracking carbon dioxide levels and distinguishing between gas and liquid forms. The device could potentially trap carbon dioxide in clathrate hydrates, a promising method for climate change mitigation.
