A new report on Science Advances developed by Mirco Kaponig and colleagues in physics and nanointegration in Germany, detailed the very basic concept of contact electrification between two metals. In a new experimental method, the researchers followed the charge of a small sphere bouncing on a grounded planar electrode on a timescale down to 1 microsecond. The team noted how the sphere discharged in the moment of contact lasting for 6 to 8 microseconds. At the moment of disruption of the electrical contact... Читать дальше...

A team of researchers from Oklahoma State University, the University of Central Oklahoma and the University of Arkansas has found that the mere sight of sick birds of their own kind is enough to set off an immune response in healthy canaries. In their paper published in the journal Biology Letters, the group describes experiments they conducted with caged birds in their lab.

A combined team of researchers from Durham University and Sea Search Research and Conservation NPC, has found that a gray whale spotted off the coast of Namibia traveled halfway around the globe to get there. In their paper published in the journal Biology Letters, the group describes collecting a tissue sample from the whale and comparing its DNA with other whales in other parts of the world.

A team of researchers from the Institute for Quantum Optics and Quantum Information and the University of Innsbruck, has developed a technique for characterizing the phases a superfluid undergoes as it changes to a supersolid and then back again. The group has written a paper describing their technique and have uploaded it to the arXiv preprint server.
