Celebrities often use their platforms to spread awareness on important issues. But while many of us have become numb to their warnings, there’s something about Harrison Ford that makes people sit up and listen.
Maybe it’s the cult following he’s acquired from playing heroic characters like Indiana Jones and Han Solo.
A team of physicists from the Massachusetts Institute of Technology (MIT) has discovered a hybrid particle that could pave the way for smaller and faster electronic devices in the future.
The hybrid particle, which was found to be a mashup of an electron and a phonon (a quasiparticle formed by vibrating atoms in a material), was detected in a strange, two-dimensional magnetic substance.
Probably the most intriguing aspect of the discovery, however, is that when the scientists measured the force between the electron and phonon, they saw that the glue, or bond, was 10 times stronger than what had previously been estimated for other known electron-phonon hybrids, according to the study which has been published in the journal Nature Communications.
Bioelectricity, the current that flows between our cells, is fundamental to our ability to think and talk and walk.
In addition, there is a growing body of evidence that recording and altering the bioelectric fields of cells and tissue plays a vital role in wound healing and even potentially fighting diseases like cancer and heart disease.
Now, for the first time, researchers at the USC Viterbi School of Engineering have created a molecular device that can do both: Record and manipulate its surrounding bioelectric field.

Harnessing the destructive potential of force and rotation, cutting tools like saws, drills, and angle grinders can obliterate the superlative properties that materials work so hard to perfect. And even when materials are designed to work against the power of these tools, the materials still often fail.
So what if instead we designed materials to work with the power of cutting tools rather than against them? While that may sound counterintuitive, it is just what an international group of researchers has done—and their preliminary tests show the ceramic–metal composite material they designed resists damage beyond shallow surface cuts.
The researchers, from Durham University, University of Surrey, and University of Stirling in the U.K. and Fraunhofer Institute and Leibniz University Hannover in Germany, developed a ceramic–metal composite that, despite being just 15% as dense as steel, is nearly uncuttable. By harnessing the power of vibration, the material directs tools’ destructive energy back upon themselves, wearing the tools down before they can inflict serious damage on the material.
Scientists have found a new “strange metal” that behaves in ways they can’t quite understand.
But the discovery could be key to finding out an explanation for a phenomenon that has troubles researchers for decades.
Most materials, such as copper and silver, behave in predictable and well understood ways, and scientists understand how their electrical conductance changes when they are heated or cooled.
