Huge vortex appears in lake in America

A giant spiralling vortex has appeared in a lake in the United States.

Video footage has captured the vortex on Lake Texoma, which is on the border between the states of Texas and Oklahoma.

It opened up after water was drained from the lake after severe floods.

The hole is two and a half metres wide but is walled off to make sure vessels and small boats are not caught up in it. (CBBC newsround)

What's a Vortex?

In fluid dynamics, a vortex is a region, in a fluid medium, in which the flow is mostly rotating on an axis line, the vortical flow that occurs either on a straight-axis or a curved-axis. The plural of vortex is either vortices or vortexes.

Once formed, vortices can move, stretch, twist, and interact in complex ways. A moving vortex carries with it some angular and linear momentum, energy, and mass. In a stationary vortex, the streamlines and pathlines are closed. In a moving or evolving vortex the streamlines and pathlines are stretched by the overall flow into loopy but open curves.

Did you know vortices spin in different directions weather you are in northern or southern hemisphere?

The Simpsons say divorce rumours are 'baseless'

They are one of TV's longest married couples, but of late there have been rumours that it's divorce-ville for Homer and Marge Simpson.

A scene from the new series of The Simpsons.

Not true, says the animated couple.

In a video posted online, called Together Forever, Marge says: "Homie and I are here to address baseless rumours that we are going to split up."

The rumour-mill kicked in after Al Jean, one of the original writers of the show, said that there could be a legal separation for the pair.

He made the comments in an interview with Variety magazine, which discussed various future storylines.

Marge and Homer have been married for 26 series of the cult TV show.

In the Youtube post, their first official statement on their marriage, Marge goes on to explain how the story was first reported before news spread around the world.

Homer then goes on to ask why "news media guys can't cover more important things".

"Now listen here, Marjorie and I are as solid as a rock," he adds.

Theropod-the first meat-eating dinosaur goes on show in Wales

This is an artist's impression of a meat-eating Jurassic dinosaur that was found on a south Wales beach in 2014.

The fossilised skeleton is only now being revealed to the public for the first time.It's a small theropod dinosaur.That's a distant cousin of the giant Tyrannosaurus Rex.It would have stood at about 50 cm high and about 2 metres long.

Nick and Rob Hanigan uncover the fossilised remains inch by inch

Fossil-hunting brothers Nick and Rob Hanigan found it at Lavernock, Vale of Glamorgan. There had been a cliff rock fall.

They have now donated it to the National Museum Wales.

Experts there believe the fossilised remains date back more than 200 million years to the very earliest part of the Jurassic Period.

The theropod is the first meat-eating dinosaur fossil to be found in Wales.

It's also one of the oldest finds from the Jurassic Period in the world.

The fossils show it had lots of small blade-like teeth. That suggests it lived on insects, small mammals and other reptiles.

The brothers spent last year carefully preparing five stone blocks to uncover the full fossil, before getting in touch with museum experts.

"This is a once-in-a-lifetime find," said Nick Hanigan. "Preparing the skull to seeing the teeth of a theropod for the first time in 200 million years was fantastic - you just can't beat that sort of thing."

'Hand' and claw bones

is brother Rob said, "It has always been our intention to donate our dinosaur to the museum for the public and scientists to see and research."
