Testosterone might be involved in explaining why men have a greater risk of heart attacks than women of similar age, according to a study funded by the British Heart Foundation (BHF) and the Biotechnology and Biological Sciences Research Council (BBSRC).
One secret to creating the world's fastest silicon-based flexible transistors: a very, very tiny knife. Working in collaboration with colleagues around the country, University of Wisconsin-Madison engineers have pioneered a unique method that could allow manufacturers to easily and cheaply fabricate high-performance transistors with wireless capabilities on huge rolls of flexible plastic.
Scientists at NJIT's Big Bear Solar Observatory (BBSO) have captured unprecedented images of a recent solar flare, including bright flare ribbons seen crossing a sunspot followed by "coronal rain," plasma that condenses in the cooling phase shortly after the flare, showering the visible surface of the Sun where it lands in brilliant explosions.
People who often mix their media consumption — texting while watching TV, or listening to music while reading — are not known for being able to hold their attention on one task. But sharpening their focus may be as simple as breathing. Researchers at the University of Wisconsin–Madison have shown that heavy media multitaskers benefited from a short meditation exercise in which they sat quietly counting their breaths.
Researchers have demonstrated proof of concept for a novel low-energy nuclear reaction imaging technique designed to detect the presence of “special nuclear materials” – weapons-grade uranium and plutonium – in cargo containers arriving at U.S. ports.
Premature birth is a harsh change of environment for a baby. Until birth, the baby is confined to the mother’s womb, surrounded by soft lighting and filtered noise. When infants are born, they are attacked by several visual, sound, and tactile stimulations. These stimulations thus constitute unpleasant factors for them. Their impact has not been studied in depth yet. Researchers from the University of Geneva (UNIGE), in collaboration with the neonatal team of the Grenoble university hospital (CHU), and the French National Center for Scientific Research (CNRS) examined the consequences of noise on the sensory abilities of premature babies. For the first time, this enabled the researchers to reveal the effect of a negative stimulus on the sensory functions of newborns. These results are available on the website of the journal Scientific Reports.
Inspired by pregnancy tests, researchers have developed a novel method to store microfluidic devices for CD4 T cell testing in extreme weather conditions for up to six months without refrigeration. These devices are used for chemotherapy monitoring, transplant patient monitoring, and especially in monitoring the efficacy of antiretroviral therapy. If produced at a large scale, the device would cost less than $1 compared with the current cost of a CD4 assay which is about $30-$50.
Engineers have created a new material with an unusual chemical structure that makes it incredibly hard and yet elastic.
