Modeling study reveals blind spots in the monitoring of plastic waste
Whether in drinking water, food or even in the air, plastic is a global problem—and the full extent of this pollution may go beyond of what we know yet. Researchers at the Karlsruhe Institute of Technology (KIT), together with partners from the Net.....»»
New analysis takes a closer look at the sterile neutrino
A new result from the MicroBooNE experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory probes the Standard Model—scientists' best theory of how the universe works. The model assumes there are three kinds of neutrinos......»»

New NASA tool helps detect "super-emitters" of methane from space
NASA scientists, using a tool designed to study how dust affects climate, have identified more than 50 spots around the world emitting major levels of methane, a development that could help combat the potent greenhouse gas......»»
Electrons with Planckian scattering in strange metals follow standard rules of orbital motion in a magnet
Strange metals, or non-Fermi liquids, are distinct states of matter that have been observed in different quantum materials, including cuprate superconductors. These states are characterized by unusual conductive properties, such as a resistivity that.....»»
Hubble captures rare "light echo" from star explosion
When a star explodes (a supernova), it sends its intense burst of light out in all directions. On rare occasions, in the months and years that follow, rings of light or "light echoes" spread out from the original supernova position......»»
