Most precise measurement of electron mass made
Scientists in Germany said Wednesday they had made the most precise measurement yet of the mass of the electron, one of the building blocks of matter.
When a black hole shreds a star, a bright flare tells the story
(Phys.org) —Enrico Ramirez-Ruiz uses computer simulations to explore the universe's most violent events, so when the first detailed observations of a star being ripped apart by a black hole were reported ...
Long predicted atomic collapse state observed in graphene: Researchers recreate elusive phenomenon with artificial nucle
The first experimental observation of a quantum mechanical phenomenon that was predicted nearly 70 years ago holds important implications for the future of graphene-based electronic devices. Working with ...

Scientists uncover the nuclear life of actin
A key building block of life, actin is one of the most abundant and highly conserved proteins in eukaryotic cells.
Superfluids: Observation of 'second sound' in a quantum gas
Second sound is a quantum mechanical phenomenon, which has been observed only in superfluid helium. Physicists from the University of Innsbruck, Austria, in collaboration with colleagues from the University ...
Cosmic glitch: Super-dense star is first ever found suddenly slowing its spin
One of the densest objects in the universe, a neutron star about 10,000 light years from Earth, has been discovered suddenly putting the brakes on its spinning speed. The event is a mystery that holds important ...
New experiments challenge fundamental understanding of electromagnetism
(Phys.org)—A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions ...

New study challenges old views about evolution of early life
A research team led by biogeochemists at the University of California, Riverside has tested a popular hypothesis in paleo-ocean chemistry, and proved it false.
Research sheds light on M.O. of unusual RNA molecules
(Phys.org) —The genes that code for proteins—more than 20,000 in total—make up only about 1 percent of the complete human genome. That entire thing—not just the genes, but also genetic junk and all ...
Study: The very first stars may have turned on when the universe was 750 million years old
As far back in time as astronomers have been able to see, the universe has had some trace of heavy elements, such as carbon and oxygen. These elements, originally churned from the explosion of massive stars, ...
