Four years removed from a frustrating “out of focus” problem with his confocal microscope, Washington State University (WSU) physicist Matthew McCluskey finds himself in the unexpected position of founder and chief technology officer of his own startup company, Klar Scientific.
Klar Scientific specializes in the development of optical instruments for materials characterization—some of which arise from McCluskey’s improvisation while working on semiconductor characterization in his lab at WSU.
New crystal-based electronics – in which a laser etches electronic circuitry into a crystal – could enable better electrical interfaces between implantable medical devices and biological tissue, according to the lead researcher behind the technology.
“Electrical conductivity affects how cells adhere to a substrate. By optically defining highly conductive regions on the crystal, cells could be manipulated and perhaps used in bioelectronic devices,” Matt McCluskey, a Washington State University professor of physics and materials science, told MDO.
Three billion years ago in a distant galaxy, two massive black holes slammed together, merged into one and sent space–time vibrations, known as gravitational waves, shooting out into the universe.
The waves passed through Earth and were detected early this year by an international team of scientists, including WSU physicists Sukanta Bose, Bernard Hall and Nairwita Mazumder.
The newfound black hole, first reported in the journal Physical Review Letters in June, has a mass about 49 times that of the sun. The collision that produced it released more power in an instant than is radiated by all the stars and galaxies in the universe at any moment.
The wavelike properties of quantum matter could lead to a scaled-down version of Star Trek technology. A new kind of tractor beam could use a beam of particles to reel in atoms or molecules, physicists propose in the May 5 Physical Review Letters.
“The idea is very reasonable,” says Philip Marston of Washington State University in Pullman. Although the results are still theoretical, “I think somebody will probably find some way to demonstrate this in the lab,” Marston says.
Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. It accelerates backwards.
The phenomenon is rarely created in laboratory conditions and can be used to explore some of the more challenging concepts of the cosmos, said Michael Forbes, a WSU assistant professor of physics and astronomy and an affiliate assistant professor at the University of Washington. The research appears today in the journal Physical Review Letters, where it is featured as an “Editor’s Suggestion.”
