The h-index has become an indicator of quality for many researchers and may influence the allocation of research funds. But some question its value.
There are two types of time travel: going back in time and going forward in time. And remarkably, people can feel time at different rates - but usually don't notice it.
Albert Einstein may have been the ultimate example of a visionary genius, but that did not stop him from twice losing his way due to beliefs that were perhaps not so scientific.
One of Einstein's weirder predictions is that massive, spinning objects exert a drag on space-time itself. Now an orbiting pair of unusual stars has revealed this effect in action.
Scientists turned Earth into one giant telescope to capture the uncapturable.
Edgar Allen Poe, Sigmund Freud and cognitive scientists have all wrestled with the human tendency to behave in ways that are irrational and self-defeating.
The crucial phase of our discovery of black holes took place in a suitably dark period of human history – World War II.
A black hole is an object with such a strong gravitational pull that nothing, not even light, can escape from it.
It's all about the strong gravitational field of the black hole.
Astronomers traced a single star as it passed close to the black hole at the centre of our galaxy, and detected the telltale signature of Einstein’s gravity in action.
A natural view of the world appealed to Albert Einstein.
Exactly 99 years after Einstein's theory of general relativity was proven right in our own solar system, scientists show that it also holds true for entire galaxies.
Jets from supermassive black holes behave in mysterious ways. Now scientists have now worked out what's really going on.
A new analysis shows how family background influences who grows up to invent. The key to turning things around? Expose kids to more inventors.
Research shows that funny people are also nicer to be around.
Isaac Newton and Albert Einstein would have bridled under today's research funding bureaucracy. It's time to allow scientists to indulge their curiosity again.
Is dark energy just an illusion, as is often suggested? To resolve the dilemma, interpreting the basic principles of general relativity in a complex Universe may need a rethink.
Astronomers report the first ever measurement of light bending around a star other than our own.
Einstein called entanglement "spooky action at a distance”. But now it's been used to design an incredibly sensitive detection method for gravitational waves.
Einstein's theories of relativity underpin our understanding of the universe, yet they're not taught in high school. How can we change that?
