BOSTON, Aug. 19, 2018 -- Many people rely on contact lenses to improve their vision. But these sight-correcting devices don't last forever -- some are intended for a single day's use -- and they are eventually disposed of in various ways. Now, scientists are reporting that throwing these lenses down the drain at the end of their use could be contributing to microplastic pollution in waterways.
CHARLOTTESVILLE, Va. - University of Virginia mechanical engineers and materials scientists, in collaboration with materials scientists at Penn State, the University of Maryland and the National Institute of Standards and Technology, have invented a "switching effect" for thermal conductivity and mechanical properties that can be incorporated into the fabrication of materials including textiles and garments.
Heavy rainfall and towering cloud heights were the findings when Hurricane Lane was scanned by the Global Precipitation Measurement mission or GPM core observatory satellite on Aug. 17. Lane strengthened to a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale.
Perinatal hypoxia associated with long-term cerebellar learning deficits and Purkinje cell misfiring
Oxygen deprivation associated with preterm birth leaves telltale signs on the brains of newborns in the form of alterations to cerebellar white matter at the cellular and the physiological levels. Now, an experimental model of this chronic hypoxia reveals that those cellular alterations have behavioral consequences.
Researchers at Tokyo Institute of Technology have honed in on an enzyme belonging to the glycerol-3-phosphate acyltransferase (GPAT) family as a promising target for increasing biofuel production from the red alga Cyanidioschyzon merolae.
Researchers have developed a system using artificial intelligence that can edit the facial expressions of actors to accurately match dubbed voices, saving time and reducing costs for the film industry. It can also be used to correct gaze and head pose in video conferencing, and enables new possibilities for video postproduction and visual effects.
When the good and bad bacteria in our mouth become imbalanced, the bad bacteria form a biofilm (aka plaque), which can cause cavities, and if left untreated over time, can lead to cardiovascular and other inflammatory diseases like diabetes and bacterial pneumonia.
A team of researchers from the University of Illinois has recently devised a practical nanotechnology-based method for detecting and treating the harmful bacteria that cause plaque and lead to tooth decay and other detrimental conditions.
In future decades the need for effective strategies for medical rehabilitation will increase significantly, because patients' rate of survival after diseases with severe functional deficits, such as a stroke, will increase. Socially assistive robots (SARs) are already being used in rehabilitation for this reason. In the journal Science Robotics, a research team led by neuroscientist Dr. Philipp Kellmeyer of the Freiburg University Medical Center and Prof. Dr.
A few little cells that are different from the rest can have a big effect. For example, individual cancer cells may be resistant to a specific chemotherapy--causing a relapse in a patient who would otherwise be cured. In the journal Angewandte Chemie, scientists have now introduced a microfluidics-based chip for the manipulation and subsequent nucleic-acid analysis of individual cells. The technique uses local electric fields to highly efficiently "trap" the cells (dielectrophoresis).
Tropical Storm Bebinca showed powerful, heavy rain-making thunderstorms on infrared satellite imagery when NASA's Terra satellite saw the storm along the northern Vietnam coast.
The Vietnam Hydrological Administration (VHA) has issued a tropical storm warning for coastal Vietnam.
Infrared light provides valuable temperature data to forecasters and cloud top temperatures give clues about highest, coldest, strongest storms within a tropical cyclone.
The rainbow is not just colors - each color of light has its own frequency. The more frequencies you have, the higher the bandwidth for transmitting information.
Only using one color of light at a time on an electronic chip currently limits technologies based on sensing changes in scattered color, such as detecting viruses in blood samples, or processing airplane images of vegetation when monitoring fields or forests.
Researchers have shown how to shuttle lithium ions back and forth into the crystal structure of a quantum material, representing a new avenue for research and potential applications in batteries, "smart windows" and brain-inspired computers containing artificial synapses.
The research centers on a material called samarium nickelate, which is a quantum material, meaning its performance taps into quantum mechanical interactions. Samarium nickelate is in a class of quantum materials called strongly correlated electron systems, which have exotic electronic and magnetic properties.
BOZEMAN - A Montana State University faculty member dedicated to researching cereal genetics and genomics for Montana farmers is part of an international research team that published an article detailing the entire sequence of the wheat genome of bread wheat. The International Wheat Genome Sequencing Consortium published the article in the prestigious journal Science this week. It is the result of 13 years of collaborative international research.
Certain female mosquitoes quickly evolve more selective mating behavior when faced with existential threats from other invasive mosquito species, with concurrent changes to certain genetic regions, according to new research from North Carolina State University. The findings shed light on the genetics behind insect mating behavior and could have implications for controlling mosquito pests that plague humans.
ALBUQUERQUE, N.M. -- If you're ever unlucky enough to have a car with metal tires, you might consider a set made from a new alloy engineered at Sandia National Laboratories. You could skid -- not drive, skid -- around the Earth's equator 500 times before wearing out the tread.
