Northwestern University professor Luis Amaral's new TopicMapping algorithm shows better accuracy and reproducibility than the leading algorithm for mining unstructured text.
Engineers have shone new light on an emerging family of solar-absorbing materials that could clear the way for cheaper and more efficient solar panels and LEDs. The materials, called perovskites, are particularly good at absorbing visible light, but had never been thoroughly studied in their purest form: as perfect single crystals. Using a new technique, researchers grew large, pure perovskite crystals and studied how electrons move through the material as light is converted to electricity.
Daniel Chitwood, Ph.D., assistant member, and his research group at the Donald Danforth Plant Science Center's in St. Louis, in collaboration with the laboratory of Neelima Sinha, Ph.D., at the University of California, Davis, are using the world's largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. They have recently reported the results of their work in the online journal, PLOS Genetics.
Little animations trying to master a computer game are teaching neuroscience researchers how the brain evolves when faced with difficult tasks. Neuroscientists at the University of Wisconsin-Madison and Michigan State University have programmed animated critters that they call 'animats.' The critters have a rudimentary neural system made of eight nodes: two sensors, two motors, and four internal computers that coordinate sensation, movement and memory.
In this week's issue of the journal Science, MIT researchers report that just four fairly vague pieces of information -- the dates and locations of four purchases -- are enough to identify 90 percent of the people in a data set recording three months of credit-card transactions by 1.1 million users.
Los Alamos National Laboratory researchers reveal a new solution-based hot-casting technique that allows growth of highly efficient and reproducible solar cells from large-area perovskite crystals.
Texting may be a more suitable treatment aid for those with mental illness than mobile applications. This is the key finding of a new study led by researchers from Clemson University in collaboration with researchers from Indiana University and the Centerstone Research Institute. The study was published in the journal Personal and Ubiquitous Computing.
The number of cities across the globe that experience heat waves has increased since the 1970s and the frequency of those heat waves has increased as well as the heat island effect amplifies global warming, find an international team of researchers.
A new study by University of Georgia ecologists finds that sedentary winter-breeding monarch butterflies are at increased risk of disease, a discovery that could apply to other migratory species as well. But, for the monarchs, there may be a relatively simple solution. The study's lead author, Dara Satterfield, said the monarchs' winter-breeding behavior is made possible by the presence of tropical milkweed and recommends gardeners gradually replace it with native milkweeds as they become available.
When blizzard warnings were in effect in New England, NASA's ISS-RapidScat instrument provided forecasters with wind speed data on the nor'easter that had hurricane-force wind gusts.
