Research by a team of chemists at the University of Toronto, led by Nobel Prize-winning researcher John Polanyi, is shedding new light on the behavior of molecules as they collide and exchange atoms during chemical reaction. ...
Water can remain liquid at temperatures far below 0 degrees Celsius. This supercooled phase is a current focus for scientific research. A theoretical model developed at São Paulo State University (UNESP) in Brazil shows ...
Arindam Banerjee, an associate professor of mechanical engineering and mechanics at Lehigh University, studies the dynamics of materials in extreme environments. He and his team have built several devices to effectively investigate ...
After 19 months without a director, the Trump administration recently tapped meteorologist Kelvin Droegemeier to lead the the White House's Office of Science and Technology Policy. Perhaps surprisingly, given the administration's ...
Atomizing liquids is vital to fuel-air mixing. Using oscillating liquid streams, breakup and drop formation can be improved compared to common straight jets. But the many dynamic interactions make it difficult for scientists ...
You don't get to swim in the sun's atmosphere unless you can prove you belong there. And the Parker Solar Probe's Faraday cup, a key sensor aboard the $1.5 billion NASA mission launching this summer, earned its stripes last ...
In the first moments after the Big Bang, the universe expanded many billions of times faster than today. Such rapid expansion is likely due to a primordial force field acting with a new particle, the inflaton. From the latest ...
In molecules, there are certain groups of atoms that are able to rotate. This movement occurs under the influence of random stimuli from the environment, and is not continuous, but occurs in jumps. It is generally believed ...
(Phys.org)—Physicists have discovered that dozens of 3-D knotted structures called "topological solitons," which have remained experimentally elusive for hundreds of years, can be created and frozen for long periods of ...
Planets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source.
