Research from the Universidad Carlos III de Madrid (UC3M), the University of Warwick and ETH Zurich has studied the effectiveness of micro-targeted political advertising on social media such as Facebook in the United States. The research concludes that it may have increased the number of Donald Trump voters by ten per cent in the 2016 presidential elections.
Nature is full of examples of large-scale collective behavior; humans also exhibit this behavior, most notably in pelotons, the mass of riders in bicycle races. Using aerial video footage of bicycle races, researchers analyzed peloton motion to determine what causes changes in the group's large-scale collective behavior and found that riders move through the peloton in a manner similar to circulation in a fluid.
There are two major shapes of bacteria, i.e., rod-shape and spherical shape. The genus Deinococcus consists of rod-shape and spherical shape species.
Scheduling and coordinating air traffic can be difficult, but taking the airlines' and passengers' delay costs into account can actually save airlines money and result in fewer delays, according to a new study from Binghamton University, State University of New York.
Princeton researchers explore methods of using carefully controlled droplets as a way to make soft, biomimetic structures. The trick comes in controlling the droplets, which form under competing influences like gravity and surface tension. A new study, published Oct. 26 in Nature Communications, explains how a deeper understanding of these highly dynamic forces can be harnessed to cheaply and quickly fabricate objects that normally require a more expensive and time-consuming process.
Social media echo chambers may reflect real-life conversations that are linked to the geographic locations of users, according to new research. The findings contradict the assumption that echo chambers -- discussions which only involve people with the same views -- are the result of online interactions alone. Conducted by City, University of London and published in the journal PLOS ONE, the study analyzed 33,889 Twitter posts from the Brexit referendum campaign period.
Millions of couples who have trouble conceiving may get relief from new research led by scientists at The University of Texas at San Antonio. The researchers have developed a high-resolution genetic map showing how men produce sperm cells. Their effort could help address genetically based challenges with male fertility, a major cause of conception problems.
After exploring every possible correlation, researchers shed new light on a long-standing question about what triggers cell division.
Raven's Advanced Progressive Matrices is a widely used standardized test to measure reasoning ability. One drawback, however, is that the test takes 40 to 60 minutes to complete. Another is that the test kit and answer sheets can cost hundreds of dollars. University of California psychologists have now developed a highly comparable free test that takes 10 minutes to complete. The user-friendly test measures abstract problem-solving ability and works on tablets and other mobile devices.
Medical diagnoses mostly focuses on resolving isolated issues. But, fixing one problem may create others and even invoke an overall health collapse. Scientists now found a new approach to assess the risks of such collapse in humans and other animals using data from wearable sensors.
