New photoacoustic endoscope fits inside a needle

Tiny imaging device lays groundwork for high-resolution 3D imaging during clinical procedures. Researchers have created a photoacoustic imaging endoscope probe that can fit inside a medical needle with an inner…

New glass-ceramic emits light when under mechanical stress

Transparent glassy material could be used to provide a light-based readout of stress in the body or buildings. Researchers have created a new glass-ceramic that emits light in response to…

Life cycle of supermassive black holes

Space study offers clearest understanding yet of the life cycle of supermassive black holes. Research uses X-ray telescopes and a new data analysis technique to describe space objects. Black holes…

Columbia Engineering roboticists discover alternative physics

A new AI program observed physical phenomena and uncovered relevant variables–a necessary precursor to any physics theory. But the variables it discovered were unexpected. Energy, Mass, Velocity. These three variables…

Major advance in semiconductor materials

High carrier mobility in cubic boron arsenide offers promise for next-gen electronics. Researchers have for the first time experimentally discovered that a cubic boron arsenide crystal offers high carrier mobility…

Hunting for dark galaxies with FAST

A large-scale neutral hydrogen (HI) survey of the local universe is one of the major science initiatives under the Five-hundred Meter Aperture Spherical radio Telescope (FAST) project. Equipped with a…
