(Phys.org)—Researchers have demonstrated that coating a cobalt film in graphene doubles the film's perpendicular magnetic anisotropy (PMA), so that it reaches a value 20 times higher than that of traditional metallic cobalt/platinum ...
(PhysOrg.com) -- In a new study, scientists have shown that simply tailoring the nanoscale geometrical parameters of dielectric structures can result in an increase in the light intensity to unprecedented levels. Theoretically, ...
A team of researchers from New Zealand, the U.S. and Canada has confirmed the first observation of a SAR arc evolving into a STEVE. In their paper published in the journal Geophysical Research Letters, the group details their ...
DNA regions susceptible to breakage and loss are genetic hot spots for important evolutionary changes, according to a Stanford study. The findings may lead to new understanding of human evolution.

Every cell in the body has the same DNA and genes, so a cell's properties and functions are determined by which genes are turned on. That's why it is critical to understand enhancers, short sections of non-coding DNA that ...

(Phys.org) -- A Cornell scientist has come up with an algorithm that can sift through 10,000 pieces of a jigsaw in 24 hours to complete the puzzle. Andrew Gallagher at Cornell University in Ithaca, New York, wrote the algorithm ...
Closely related animal species can look physically different, but you might be surprised to learn that those differences can result not only from DNA sequence changes that alter proteins' structure or function, but also because ...
