Robotics-Based Study Provides Insight Into Predator-Prey Interactions

A research team led by New York University professor Maurizio Porfiri put forth a robotics-based study to control information flow in predator-prey interactions, as well as test the validity of transfer entropy when attempting to understand causal influences of the system. They report their findings this week in the journal Chaos, from AIP Publishing.

Leading the Way: ORNL Builds More Reliable, Longer-Lasting Targets for High-Powered Neutron Scattering

17-G00354_Target_Web_proof3.jpg

The Spallation Neutron Source at ORNL was the first neutron facility to use a liquid mercury target for neutron production when it came online in 2006. The SNS is now a world leader in understanding how mercury targets perform at up to 1.4 megawatts of power. The ultimate objective is to build even more reliable and long-lasting targets for consistent neutron production.

3-D Models Help Scientists Gauge Flood Impact

Constantinescu1.jpg

Using one of the world’s most powerful supercomputers—Titan, the 27-petaflop Cray XK7 at the Oak Ridge Leadership Computing Facility (OLCF)—a University of Iowa team performed one of the first highly resolved, 3-D, volume-of-fluid Reynolds-averaged Navier–Stokes (RANS) simulations of a dam break in a natural environment. The simulation allowed the team to map precise water levels for actual flood events over time.

Fund for Lake Michigan Backs University of Wisconsin-Milwaukee Ground-Breaking Study of Aquatic Species

The University of Wisconsin-Milwaukee School of Freshwater Sciences has received a grant to sequence the DNA and analyze the genetic makeup of three key aquatic species, including Yellow Perch and the Green Bay Mayfly. the University of Wisconsin-Milwaukee (UWM) School of Freshwater Sciences to sequence the DNA and analyze the genetic makeup of three aquatic species, including Yellow Perch and the Green Bay Mayfly. The third species to be sequenced may include important fisheries species such as Lake Whitefish, Lake Trout, Northern Pike, or Muskellunge.

A Berkeley Lab-led report highlights a new, compact technique for producing beams with precisely controlled energy and direction that could “see” through thick steel and concrete to more easily detect and identify concealed or smuggled nuclear materials for national security and other applications.

Study Reveals Origin of Modern Dog Has a Single Geographic Origin

Fig1_NR.jpg

By analyzing the DNA of two prehistoric dogs from Germany, an international research team led by Krishna R. Veeramah, PhD, Assistant Professor of Ecology & Evolution in the College of Arts & Sciences at Stony Brook University, has determined that their genomes were the probable ancestors of modern European dogs. The finding, to be published in Nature Communications, suggests a single domestication event of modern dogs from a population of gray wolves that occurred between 20,000 and 40,000 years ago.
