A scientist places a water sample onto a custom-made platform before a test. Each water sample contains microorganisms such as the parasite Giardia and adenoviruses, both of which can make humans sick. Credit: T. Larason/NIST NIST researchers describe unique system for testing how well narrow wavebands of UV light kill […]

Credit: Tomsk Polytechnic University Developed a new 2D material to produce hydrogen, which is the basis of alternative energy; the material efficiently generates hydrogen molecules from fresh, salt, and polluted water by exposure to sunlight. Scientists of Tomsk Polytechnic University jointly with teams from the University of Chemistry and Technology, […]

Circularly polarized laser light goes through the PCN device and comes out the other side as VUV polarized in the opposite direction. Credit: © 2020 Konishi et al. Spectroscopy is the use of light to analyze physical objects and biological samples. Different kinds of light can provide different kinds of […]

In first extensive study of commercial avocado oil quality and purity, UC Davis researchers find majority impure or stale. Food scientist says standards needed to protect consumers and industry. Consumer demand is rising for all things avocado, including oil made from the fruit. Avocado oil is a great source of […]

In 2017, Stanford University researchers presented a new device that mimics the brain’s efficient and low-energy neural learning process. It was an artificial version of a synapse — the gap across which neurotransmitters travel to communicate between neurons — made from organic materials. In 2019, the researchers assembled nine of […]

Scientists have long debated which genetic information carrier — DNA or RNA — started life on Earth, but a new study suggests life could have begun with a bit of both. The research, led by scientists from the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB), in Cambridge, shows for the first time […]

New binding solution targets construction uses. Revolutionary ‘green’ types of bricks and construction materials could be made from recycled PVC, waste plant fibers or sand with the help of a remarkable new kind of rubber polymer discovered by Australian scientists. The rubber polymer, itself made from sulfur and canola oil, […]

animation Billiard-like break shot to cell-membrane structures triggers brain’s loss of consciousness from anesthesia, scientists find. Surgery would be inconceivable without general anesthesia, so it may come as a surprise that despite its 175-year history of medical use, doctors and scientists have been unable to explain how anesthetics temporarily render […]
