Long-sought magnetic mechanism observed in exotic hybrid materials
Scientists have measured the subatomic intricacies of an exotic phenomenon first predicted more than 60 years ago. This so-called van Vleck magnetism is the key to harnessing the quantum quirks of topological ...
Physicists propose method to measure variations in the speed of light
Female reproductive tract assists swimming sperm
In mammalian reproduction, sperm have a tough task: like trout swimming upstream, they must swim against a current through a convoluted female reproductive tract in search of the unfertilized egg.
New understanding of electromagnetism could enable 'antennas on a chip'
A team of researchers from the University of Cambridge have unravelled one of the mysteries of electromagnetism, which could enable the design of antennas small enough to be integrated into an electronic ...
Flip-flopping black holes spin to the end of the dance
When black holes tango, one massive partner spins head over heels (or in this case heels over head) until the merger is complete, said researchers at Rochester Institute of Technology in a paper published ...
Photon 'afterglow' could transmit information without transmitting energy
Quantum computers could greatly accelerate machine learning
Universe may be on the brink of collapse (on the cosmological timescale)
Study explains why soil and sand get stronger when they are struck harder
When a missile or meteor strikes the earth, the havoc above ground is obvious, but the details of what happens below ground are harder to see.
Black holes don't erase information, scientists say
The "information loss paradox" in black holes—a problem that has plagued physics for nearly 40 years—may not exist.
Researchers use 'soft' nanoparticles to model behavior at interfaces
Where water and oil meet, a two-dimensional world exists. This interface presents a potentially useful set of properties for chemists and engineers, but getting anything more complex than a soap molecule ...
'Explosive' atom movement is new window into growing metal nanostructures
"The textbook said we should see slow, gradual and random. But what we saw? BOOM! Fast, explosive and organized!" said Michael Tringides, physicist at the U.S. Department of Energy's Ames Laboratory and a ...
Under the microscope, strong-swimming swamp bacteria spontaneously organize into crystals
Insects form swarms, fish school, birds flock together. Likewise, one species of bacteria forms dynamic, living crystals, says new research from Rockefeller University. Biophysicists have revealed that fast-swimming, ...
New insights found in black hole collisions
New research provides revelations about the most energetic event in the universe—the merging of two spinning, orbiting black holes into a much larger black hole.
