Researchers at the Southern University of Science and Technology in China ask if gravitons can be promising candidates for dark matter components.
Ultra-cold atoms help test fundamental theory of solids
Cold ytterbium atoms were used to test a fundamental theory which describes phenomena in solids such as magnetism and superconductivity.
Upper mass limit of massive stars revisited
Physicists at the Gemini Observatory have found a new mass limit for massive stars, and found it to be lower than previously thought.
Cooling particle beams to study the hottest topics in physics
A new experimental technique could push the capabilities of particle accelerators in exploring the subatomic world.
String theory used to describe the expanding universe
To address unknown quantum gravitational effects in the early universe, physicists have recruited string theory to help solve the problem.
Artificial physicist to unravel the laws of nature
Scientists hope that a new machine learning algorithm could one day be used to automate the discovery of new physical laws.
