New research reveals that quantum effects defy the universality of free fall, providing a potential experimental pathway to test quantum gravity.
Scientists detect the X-ray signature of a single atom
A new technique can detect the X-ray signature of an individual atom, even determining the structure of its electron orbits.
Scientists achieve 100 million degrees Kelvin with new compact fusion reactor
The most compact nuclear fusion reactor built to date could provide a more affordable and sustainable means of future fusion energy.
Galactic clusters may be key to testing competing theories of dark matter and dark energy
Scientists propose a modified cosmological model that challenges the existence of dark matter and dark energy.
Quantum tunneling may have ruled out a popular theory of dark matter
The composition of dark matter remains a mystery, but a new theory involving quantum tunneling may have eliminated some candidates.
Could dark matter be measured around black holes?
Dark matter could be aggregating around black holes, providing a possible means of indirectly measuring its properties.
Violets help scientists build a 4D-printed catapult
Taking inspiration from nature, scientists create a two-component catapult that overcomes limitations in 4D printing.
How does rotation affect the quantum properties of electrons?
A study explores how the behavior of electrons changes on the mesoscale under magnetic fields and rotation.
Searching for the true theory of electromagnetism
Scientists probe cosmic microwave background and black hole radiation to test our understanding of electromagnetism.
Observations shed light on neutron star paradox
Astronomers have observed neutron stars that emit more energy than is theoretically possible, and now an explanation might be in the works.
