(Phys.org)—Although quantum theory can explain three of the four forces in nature, scientists currently rely on general relativity to explain the fourth force, gravity. However, no one is quite sure of how gravity works ...
(Phys.org)—Researchers at Sandia Labs have used a large x-ray machine to create high-density plasma that approximates the photosphere of white dwarf stars. The team has posted a paper describing the process and how it ...
(Phys.org)—Isabella Velicogna's office in UC Irvine's Croul Hall looks like it belongs to an artist instead of a university scientist. Her paintings and drawings—including charming sketches of mice—adorn the walls, ...
