From the earliest stages of the hot Big Bang (and even before) to our dark energy-dominated present, how and when did the Universe grow up?
The solution involves the infamous Navier-Stokes equations, which are so difficult, there is a $1-million prize for solving them.
In a citizen science project, thousands of pet dogs are helping scientists to understand what happens to memory and cognition in old age.
Earth exoplanet direct imaging degraded
NASA has finally chosen which flagship mission, like Hubble and JWST, will launch in ~2040. Detecting alien life is now a reachable goal.
Hundreds of these cannabis-related chemicals now exist, both natural and synthetic, inspiring researchers in search of medical breakthroughs.
