Exercise neuroscientist Wendy Suzuki explains how your brain can age gracefully and optimally — and it starts with just a 10-minute walk.
A spherical structure nearly one billion light-years wide has been spotted in the nearby Universe, dating all the way back to the Big Bang.
This is especially true for three key groups.
The matter that creates black holes won't be what comes out when they evaporate. Will the black hole information paradox ever be solved?

In 1987, the closest supernova directly observed in nearly 400 years occurred. Will a pulsar arise from those ashes? JWST offers clues.
Experiments on suborbital rockets are revealing how to make a better iron furnace.
When it comes to predicting the energy of empty space, the two leading theories disagree by a factor of 100 googol quintillion.
The asteroid is expected to come within 140,000 miles of Earth — well inside the moon’s orbit.
Over a third are worried that vaccines can cause "canine autism."
Football is a risky sport, but bicycling to work is far more dangerous.
Three fundamental forces matter inside an atom, but gravity is mind-bogglingly weak on those scales. Could extra dimensions explain why?
A relatively new interpretation of quantum mechanics asks us to reimagine the process of science itself.
Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn't instant.
Looking at our planet with post-Copernican eyes has the power to change how we relate to it and each other.
