Lasers with a wavelength of two microns could move the boundaries of surgery and molecule detection. Researchers at EPFL have managed to generate such lasers using a simple and inexpensive method.
Researchers at Institute for Molecular Sciences reported that a mammalian photoreceptive protein melanopsin spontaneously releases the chromophore retinal. The property would be important to regulate non-visual photoreception in mammals.
Striga, also known as witchweed, is a parasitic plant that affects 100 million people in sub-Saharan Africa. Researchers from the University of Toronto have made a discovery that could lead to more effective ways to protect farmers' crops.
Infrared data from NASA-NOAA's Suomi NPP satellite showed Tropical Storm Oho weakening over cool waters and transitioning into an extra-tropical cyclone while being battered by strong wind shear.
The study, published online in the Water, Air & Soil Pollution journal (Springer) defines an accurate, inexpensive, high-throughput, and rapid alternative for screening of pathogens from various environmental samples. 'This is the first study to comprehensively assess pathogen concentrations in such a broad variety of environmental sample types while achieving multiple pathogen detection with complete parallel testing by standard (or traditional) methods,' Orlofsky explains.
While the cleaning of car exhausts is among the best known applications of catalytic processes, it is only the tip of the iceberg. Practically the entire chemical industry relies on catalytic reactions. Therefore, catalyst design plays a key role in improving these processes. An international team of scientists has now developed a concept, that elegantly correlates geometric and adsorption properties. They validated their approach by designing a new platinum-based catalyst for fuel cell applications.
More than 99 percent of the time, two words are enough for people with normal hearing to distinguish the voice of a close friend or relative amongst other voices, says the University of Montreal's Julien Plante-Hébert.
NASA's Aqua satellite passed over Tropical Storm Choi-wan as it moved over cooler waters and was becoming an extra-tropical storm.
Infrared data from NASA's Aqua satellite showed Hurricane Joaquin weakening over cooler waters and transitioning into a post-tropical cyclone.
For nearly nine years, researchers at Lund University have been working on developing implantable electrodes that can capture signals from single neurons in the brain over a long period of time -- without causing brain tissue damage. They are now one big step closer to reaching this goal, and the results are published in the scientific journal Frontiers in Neuroscience.
