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.
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
Universe may be on the brink of collapse (on the cosmological timescale)
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 ...
