Astronomers at Penn State have nicknamed the objects “universe breakers,” which may be unusual black hole atmospheres and could represent a missing link in the fast growth of supermassive black holes.

A line of engineering research seeks to develop computers that can tackle a class of challenges called combinatorial optimization problems. These are common in real-world applications such as ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

The ability to detect vocal sounds, and the more specialized skill of recognizing calls from one's own species, is supported by evolutionarily ancient brain mechanisms, according to a new study from ...

Quantum dots of various sizes will fluoresce in different colours when excited by a purple laser pointer. They do not fluoresce when a red laser shines through them. Turn off the room lights. Using ...
