Researchers at Rice University have found that gently squeezing a crystal of iron sulfide can change two of its unusual properties at the same time: its tiny magnetic signal and the way electricity moves through it. The result gives scientists a clearer picture of how a newly recognized class of magnetic materials works and suggests […] Time-reversal symmetry is an exotic behavior found in systems whose internal physics looks different when running forward versus backward in time. For some time, physicists have searched for this behavior in systems with almost no overall magnetization. Such phases are highly prized for spintronics, where information is carried using the quantum spins of electrons. Go […] Astronomers have linked an X-ray flash discovered by the Einstein Probe to a known type of supernova with unusual features that point to the birth of an ultra-dense, rapidly spinning magnetar. The paper outlining this finding was published in The Astrophysical Journal Letters on July 22. Go to Source The strongest glasses have an Achilles’ heel that causes them to fail catastrophically when pushed past their limit. They do not bend or stretch, as all damage concentrates into a single plane and the material fails in an instant. This brittleness has long capped the usefulness of high-stability amorphous solids, from bulk metallic glasses to […] Body camera footage shows officers wading through tall grass to reach the two adults and child after they had been lost for three days Go to Source Theoretical physicists have long predicted the existence of millicharged particles (mCPs), hypothetical particles that carry a very small electric charge. These particles are expected to interact very weakly with ordinary matter and electromagnetic fields; hence, they would be difficult to detect in conventional particle physics experiments. Go to Source The department is hiring more victim specialists, civilian employees who have backgrounds in social work and undergo additional training provided by CPD Go to Source Astronomers at MIT and elsewhere have spotted an extremely bright red spot in the early universe. The object resembles an enormous star, roughly the size of our solar system. But it also is putting out 100 billion times more energy than any known star can physically produce. In fact, such energies are closer to what […] Many fascinating phases in quantum materials emerge when electrons, atoms and other microscopic components begin to act collectively. But these phases do not necessarily appear out of nowhere when a material crosses a transition temperature. Before long-range order develops, microscopic fluctuations can already be present. Go to Source NASA is planning to send three small rovers to the moon with a single instruction: Work out among yourselves how to explore a patch of ground. Go to Source A new paper published in Physical Review Letters reveals that a leading dark matter candidate—the hypothetical “dark photon”—would not have heated the early universe as previously thought. The finding opens a vast region for experimental searches and could change the hunt for dark matter. Go to Source Neptune’s moon and ring system stand out among the giant planets because of the strange imbalance between its one very large moon and its many tiny moons. Its largest moon, Triton, makes up more than 99% of the mass of all satellites orbiting the planet while orbiting retrograde compared with Neptune’s rotation. The predominant theory […] Fusion reactors, devices that generate energy by fusing light atomic nuclei at extremely high temperatures, could contribute to ongoing efforts aimed at producing electricity more sustainably. The extreme environment inside these devices, however, can damage materials that surround the superheated, electrically charged plasma where the nuclear fusion reaction takes place.

Farris was arrested for painting the words “Clean hands dirty $” on the monument, and placing bubbles in a fountain Go to Source A Solano County jury found Harvey Edward Harris Jr. guilty of personally inflicting serious injury on a police animal while armed with a knife and evading an officer with willful disregard Go to Source |
