The biggest and the baddest among meat-eating dinosaurs, Spinosaurus may have also been the first dinosaur to take to the water, swimming in North Africa's rivers some 97 million years ago, researchers reported on Thursday.

A photographer has captured an image of what she believes to be a creature from the deep.
According to legend, when Damocles declared that his king, Dionysius, must have a posh and easy life, Dionysius offered to trade places with Damocles. There was only one catch. Dionysius decreed that a sword be suspended over the throne by a single horse hair, so that Damocles would always know the peril of being king. Since then the Sword of Damocles has come to represent a threat of doom that could strike without warning. While the prospect of living under a hanging sword doesn't seem pleasant, stories of impending doom are quite popular, particularly within popular science.
Black holes are basically "game over, man," for anything that gets too close to them, but they aren't invincible. In fact, they're always in the process of self-destructing. We'll look at how they fizzle out, and see if we can help them do it faster.
A star cluster some 80,000 light-years from Earth looks mysteriously deficient in the element lithium, just like nearby stars, astronomers reported on Wednesday.
Quasars are the brightest objects in the universe, and display a mysterious diversity in their appearance that has puzzled astronomers for more than two decades.
In the visible spectrum, Jupiter is a bright, star-like point in the night sky. Viewing it with the naked eye, it would be easy to confuse it with a star except for the fact that it doesn't twinkle. At radio frequencies Jupiter appears very different. It doesn't have a simple round shape, for example, and it is extraordinarily bright. So bright that it can outshine the Sun at some radio frequencies.
Giant alien planets known as "hot Jupiters" orbit their stars much closer than Mercury does the sun. But the mystery of the origins of hot Jupiters deepened when astronomers recently discovered the scorching orbits of these worlds are often bizarrely skewed, tilted when compared with the equators of their stars.
So that's what the sun sounds like.
Powerful solar flares from the sun this week may amplify the northern lights displays over parts of the northern United States through the weekend, space weather scientists say.
A massive explosion on the Sun has sent a solar storm heading straight for Earth, experts have said, which may disrupt communications equipment and power grids when it strikes.
A team of scientists led by Carnegie's Jacqueline Faherty has discovered the first evidence of water ice clouds on an object outside of our own Solar System. Water ice clouds exist on our own gas giant planets--Jupiter, Saturn, Uranus, and Neptune--but have not been seen outside of the planets orbiting our Sun until now. Their findings are published today by The Astrophysical Journal Letters and are available here.
A Stanford engineering team has built a radio the size of an ant, a device so energy efficient that it gathers all the power it needs from the same electromagnetic waves that carry signals to its receiving antenna – no batteries required.
We often describe songs using terms like "warm" and "dreamy" - but do these words mean anything to a computer?
Being in a coma for week was reportedly a fast track method of learning Mandarin for this young man.
Loneliness breeds wishful thinking, according to a new study that finds that eerily unrealistic faces seem more realistic to people when they feel isolated and alone.
