New insight into elusive antimatter can help unravel universe's mysteries

Âé¶¹ÒùÔºicists have believed that the universe is made of both matter and antimatter since the 1930s. While we are well aware of what the physical matter is, antimatter has remained an elusive substance.

History shows experiments to be just as key as theory in gravity physics

In the 1950s and earlier, the gravity theory of Einstein's general relativity was largely a theoretical science. In a new paper published in EPJ H, Jim Peebles, a physicist and theoretical cosmologist who is currently the ...

Researchers say 2-D boron may be best for flexible electronics

Though they're touted as ideal for electronics, two-dimensional materials like graphene may be too flat and hard to stretch to serve in flexible, wearable devices. "Wavy" borophene might be better, according to Rice University ...
