Tropical Cyclone Gaja continued to track toward a landfall in southeastern India when NASA-NOAA's Suomi NPP satellite flew over the Bay of Bengal and provided a visible image of the storm.
While making smart glue, a team of engineers discovered a handy byproduct: hydrogen peroxide. In microgel form, it reduces bacteria and virus ability to infect by at least 99.9 percent.
The train car dedicated to transporting John Ringling across the country, often alongside his infamous circus, is now more accessible to the public due to the 3D printing of several spare train parts.
Male salmon are maturing earlier and becoming smaller, and it shows in their genes. This was the discovery of a study that examined scale samples from salmon over a 40-year period, and looked at the population genetic profile of a gene that determines salmon's age of maturity and size. The results show that the 'big salmon gene version' has become rarer in the population over time, and has been replaced by the 'small salmon gene version'.
In 2011, researchers proposed that artificial guide stars could be used to measure the Earth's magnetic field in the mesosphere. An international group of scientists has recently managed to do this with a high degree of precision. The technique may also help to identify magnetic structures in the solid Earth's lithosphere, to monitor space weather, and to measure electrical currents in the part of the atmosphere called ionosphere.
Fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult for the starting material for the reaction -- hydrogen -- to reach the enzyme-loaded electrode. Researchers solved this problem by combining previously developed concepts for packaging the enzymes with gas diffusion electrode technology.
Researchers developed a versatile remote gaming interface that allowed experts as well as hundreds of citizen scientists all over the world through multiplayer collaboration and in real time to optimize a quantum gas experiment in a lab at Aarhus University. Both teams quickly used the interface to dramatically improve upon the previous best solutions, that scientists had established after months of careful optimization. The experiment aims to unravel how humans solve complex, natural science problems.
Photo-based information services that use image recognition can identify a user's location and other private information, such as personal interests and tendencies. Osaka University researchers developed an encryption-free framework called EnfPire to preserve users' privacy. EnfPire transforms a visual feature extracted from a photo so that it cannot be uniquely identified. The photo-based information service's server returns a set of candidates, which the user compares with the original image to determine the final recognition result.
A research team from ITMO University and the Australian National University has discovered that different metasurfaces exhibit the same behavior provided a symmetry breaking is introduced to their unit cells 'meta-atoms'. Asymmetry of meta-atoms results in high-quality (high Q) resonances in the transmittance spectra of metasurfaces. It opens the way to control an optical response, which is highly desirable for practical applications. The results of this research were published in Physical Review Letters.
A study is the first to use qualitative research to gain deeper insight into law enforcement officers' personal experiences and perspectives on the use of body-worn cameras in a post-Ferguson era. Based on a long and deep immersion in the field, researchers have generated insider knowledge on one of the most overt strategic changes to modern American policing.
