It was taken by Frederic Labaune of Education Nationale in Auxonne, France, using episcopy and stacking.
Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT. The researchers evaluated an emerging method of power generation called pressure retarded osmosis, in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane.
The University of Waterloo has unveiled a new satellite image of Antarctica, and the imagery will help scientists all over the world gain new insight into the effects of climate change. The mosaic is free and fully accessible to the academic world and the public. Using Synthetic Aperture Radar with multiple polarization modes aboard the RADARSAT-2 satellite, the CSA collected more than 3,150 images of the continent.
Laser physicists have found a way to make atomic-force microscope probes 20 times more sensitive and capable of detecting forces as small as the weight of an individual virus. The technique, developed by researchers in the Quantum Optics Group of Australian National University’s Research School of Physics and Engineering, hinges on using laser beams to cool a nanowire probe to minus 265 degrees Celsius.
NASA's Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken on August 20, 1989, at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach on August 25.
MIT spinout Akselos has developed novel software, based on years of research at the Institute, which uses precalculated supercomputer data for structural components — like simulated “Legos” — to solve FEA models in seconds. Hundreds of engineers in the mining, power-generation, and oil and gas industries are now using Akselos software.
Researchers in Bangladesh have designed a computer program that can accurately recognize users’ emotional states as much as 87 percent of the time, depending on the emotion. Writing in the journal Behaviour & Information Technology, A.F.M. Nazmul Haque Nahin and his colleagues describe how their study combined — for the first time — two established ways of detecting user emotions: keystroke dynamics and text-pattern analysis.
This 160X photo of Mizapin antidepressant drug crystals received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Robert Markus of Stockholm University using polarized light and differential interference contrast.
As a report from the Obama administration warns that one in four bridges in the United States needs significant repair or cannot handle automobile traffic, Tufts University engineers are employing wireless sensors and flying robots that could have the potential to help authorities monitor the condition of bridges in real time.
IBM announced it is collaborating with DESY, a national research center in Germany, to speed up management and storage of massive volumes of x-ray data. The planned Big Data and Analytics architecture can handle more than 20 gigabyte per second of data at peak performance and help scientists worldwide gain faster insights into the atomic structure of novel semiconductors, catalysts, biological cells and other samples.
The destructive results of a mighty supernova explosion reveal themselves in a delicate blend of infrared and X-ray light, as seen in this image from NASA’s Spitzer Space Telescope and Chandra X-Ray Observatory, and the European Space Agency's XMM-Newton. The bubbly cloud is an irregular shock wave, generated by a supernova that would have been witnessed on Earth 3,700 years ago.
Our individual genetic make-up determines the effect that stress has on our emotional centers. Not every individual reacts in the same way to life events that produce the same degree of stress. Some grow as a result of the crisis, whereas others break down and fall ill, for example with depression. The outcome is determined by a complex interaction between depression gene versions and environmental factors.
Recently, the Harvard-Smithsonian Center for Astrophysics unveiled an unprecedented simulation of the universe’s development. Called the Illustris project, the simulation depicts more than 13 billion years of cosmic evolution across a cube of the universe that’s 350-million-light-years on each side. But why was it important to conduct such a simulation?
This 25X photo of a fruit fly larval brain received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Dr. Christian Klämbt and Ann Christin Bauke of the University of Muenster using confocal microscopy.
In the age of big data, visualization tools are vital. With a single glance at a graphic display, a human being can recognize patterns that a computer might fail to find even after hours of analysis. But what if there are aberrations in the patterns? Or what if there’s just a suggestion of a visual pattern that’s not distinct enough to justify any strong inferences? Or what if the pattern is clear, but not what was to be expected?
New supercomputing calculations provide the first evidence that particles predicted by the theory of quark-gluon interactions, but never before observed, are being produced in heavy-ion collisions at the Relativistic Heavy Ion Collider. These heavy strange baryons, containing at least one strange quark, still cannot be observed directly, but instead make their presence known by lowering the temperature at which other baryons "freeze out"
On August 19, 2014, National Aviation Day, a lot of people reflected on how far aviation has come in the last century. Could this be the future — a plane with many electric motors that can hover like a helicopter and fly like a plane, and that could revolutionize air travel?
The spines along its back were thought to be legs, its legs thought to be tentacles along its back, and its head was mistaken for its tail. The animal, known as Hallucigenia due to its otherworldly appearance, had been considered an ‘evolutionary misfit’ as it was not clear how it related to modern animal groups. Researchers have discovered an important link...
A wealth of images of Earth at night taken by astronauts on the International Space Station (ISS) could help save energy, contribute to better human health and safety and improve our understanding of atmospheric chemistry. But, scientists need your help to make that happen.
One of the Expedition 40 crew members aboard the International Space Station photographed this nighttime image showing city lights in at least half a dozen southern states from some 225 miles above the home planet. Lights from areas in the Gulf Coast states of Texas, Louisiana, Mississippi and Alabama, as well as some of the states that border them on the north, are visible.
The first thousand-robot flash mob has assembled at Harvard University. Instead of one highly-complex robot, a “kilo” of robots collaborate, providing a simple platform for the enactment of complex behaviors. Called Kilobots, these extremely simple robots are each just a few centimeters across and stand on three pin-like legs.
This 200X photo of guanidine hydrochloride, a chaotropic salt used to denature proteins, received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken by Dr. Christopher Benjamin Jackson of IKELOS GmbH in Berne, Switzerland, using polarized light.
There may be itsy-bitsy aliens among us. Scientists say seven microscopic particles collected by NASA's comet-chasing spacecraft, Stardust, appear to have originated outside our solar system. If confirmed, this would be the world's first sampling of contemporary interstellar dust.
A photo is worth a thousand words, but what if the image could also represent thousands of other images? New software seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can give users the photographic gist of a kid on Santa’s lap or housecats. It works by generating an image that literally averages the key features of the other photos.
