Stephen Hawking's black hole theory has big implications for the shape of the universe, new study claims
Elusive black hole radiation predicted by Stephen Hawking may have influenced the way the universe took shape after the Big Bang, new research suggests.
Silent X chromosome genes 'reawaken' in older females, perhaps boosting brain power, study finds
Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.
Weird repeating explosion beyond the Milky Way is one of the hottest blasts scientists have ever seen
Researchers conducted the first-ever near-infrared analysis of an extragalactic recurrent nova and found it is one of the hottest nova explosions ever discovered.
In a 1st, trial finds vitamin D supplements may slow multiple sclerosis. But questions remain.
A new clinical trial has shown for the first time that taking high doses of vitamin D could stave off the progression of multiple sclerosis. However, much more research is warranted to confirm these findings.
Self-bending beams can deliver sound waves only to your ear in a crowd
By combining ultrasound with a concept called nonlinear acoustics, you can create sound that stays silent until it reaches a specific location.
Scientists break down cheap plastic using the air — and turn it into something far more valuable
Scientists developed a new method for breaking down one of the most common plastics to a byproduct that can be upcycled into more valuable materials.
High-school student accidentally discovers black hole 'light echo' twice as wide as the Milky Way
While sifting out signatures of supernova remnants, a high-schooler stumbled upon the afterglow of a dormant black hole. It may be one of the largest ever seen.
Scientists discover smallest galaxy ever seen: 'It's like having a perfectly functional human being that's the size of a grain of rice'
