Article describes production of multiscale turbulence in fusion plasmas through heating of ions and electrons.
A new microchip technology capable of optically transferring data could solve a severe bottleneck in current devices by speeding data transfer and reducing energy consumption by orders of magnitude, according to an article published in the April 19, 2018 issue of Nature.
Using the photo-sharing site Instagram as a test case, Columbia researchers demonstrate how two common recommendation algorithms amplify a network effect known as homophily in which similar or like-minded people cluster together. They further show how algorithms turned loose on a network with homophily effectively make women less visible; they found that the women in their dataset, whose photos were slightly less likely to be 'liked' or commented on, became even less popular once recommendation algorithms were introduced.
Need stronger timber, better biofuels or new sources of green chemicals? A systems biology model developed over decades of research led by NC State University will accelerate progress in engineering trees for specific needs.
You can wear an exoskeleton, but it won't turn you into a superhero. In the journal Applied Ergonomics, researchers report that that a commercially available exoskeleton relieved stress on the arms just as it was supposed to -- but it increased stress on the back by more than 50 percent.
A new theory of how compression and tension can affect the reactivity of metal catalysts could be helpful in designing new and better catalysts.
Astronomers developed a 'guide star' adaptive optics technique to obtain the most crystal-clear and precise telescopic images of distant galaxies, stars and planets. Now a team of scientists are borrowing the very same trick. They've combined it with lattice light-sheet to create a new microscope to capture unprecedented images of biology. The work -- a collaboration between researchers at Howard Hughes Medical Institute, Boston Children's Hospital and Harvard Medical School -- is detailed in a new paper in Science.
Graphene Flagship researchers reach the ultimate level of light confinement -- the space of one atom. This will pave the way to ultra-small optical switches, detectors and sensors.
Joint research between Tampere University of Technology, (Finland) and University of Tübingen (Germany) has shown that carefully structured light and matching arrangements of metal nanostructures can be combined to alter the properties of the generated light at the nanometer scale. The teams have shown that the efficiency of nonlinear optical fields generated from the oligomers is strongly influenced by how the constituents of the oligomer constituents are illuminated by structured light.
An international team of researchers led by professor Niklas Arnberg at Umeå University, shows that adenovirus binds to a specific type of carbohydrate that is overexpressed on certain types of cancer cells. The discovery opens up new opportunities for the development of virus-based cancer therapy. The study is published in the latest issue of the scientific journal Proceedings of the National Academy of Sciences.
