New climate change study: Number of people suffering extreme droughts will double

Michigan State University is leading a global research effort to offer the first worldwide view of how climate change could affect water availability and drought severity in the decades to come. By the late 21st century, global land area and population facing extreme droughts could more than double increasing from 3% during 1976-2005 to 7%-8%, according to Yadu Pokhrel, associate professor of civil and environmental engineering in MSU s College of Engineering, and lead author of the research published in Nature Climate Change. ....

New York, NY January 11, 2021 Like a longtime couple who can predict each other s every move, a Columbia Engineering robot has learned to predict its partner robot s future actions and goals based on just a few initial video frames.
When two primates are cooped up together for a long time, we quickly learn to predict the near-term actions of our roommates, co-workers or family members. Our ability to anticipate the actions of others makes it easier for us to successfully live and work together. In contrast, even the most intelligent and advanced robots have remained notoriously inept at this sort of social communication. This may be about to change. ....

More than 2,200 people are injured in toboggan accidents in Austria every year. On average, annually two accidents are fatal. In the 2019/20 toboggan season, as many as five people died. Collisions with stationary obstacles such as trees are among the most frequent causes of death. Researchers from the KFV (Austrian Road Safety Board) and the Vehicle Safety Institute at Graz University of Technology have now performed computer simulations using virtual human models to investigate which measures can reduce the risk of injury when tobogganing. Tobogganing is popular, year after year, many serious accidents occur. Detailed investigations, e.g. which speeds cause which injuries, are essential for prevention work. The results of our crash-simulations are alarming. Because the safety of a simple tob ....

The spiky structure that erupts from the smooth surface of a ferrofluid when a magnet is brought close can be predicted more accurately than previously thought. KAUST researchers have shown that computational algorithms can calculate the ferrofluid s bristling response to a magnet by simulating only the liquid s surface layer.
Ferrofluids are liquid suspensions of iron-based particles that behave like a regular fluid, but once a magnet is present, the ferrofluid rapidly shape-shifts to form spikes that align with the magnetic field. Originally developed by NASA, ferrofluids have numerous uses ranging from advanced electronics to nanomedicine and have the potential for even ....
