Horn wins WBO welterweight title defense against Corcoran

  Horn wins WBO welterweight title defense against Corcoran Jeff Horn followed up his contentious WBO welterweight title win over Manny Pacquiao with a successful first defense against Gary Corcoran. Now he's heading to America. The former school teacher from Australia won by technical knockout in the 11th round Wednesday when Corcoran's corner threw in the towel with the England-based boxer bleeding from a deep cut above his left eye.

In essence, they were perhaps too successful for their own good ." 'BLANK CANVAS'. This saturation of the Earth caused the dinosaurs to become increasingly specialised to live in their existing environment, resulting in a fundamental change in the way they evolved and produced new species.

UK researchers believe they were already in decline before the killer asteroid hit because they had occupied every habitat on Earth.

From their roots in South America, the dinosaurs migrated "in a frenzy of movement to cover the planet".

Hundreds of different dinosaurs appeared, from the ferocious T. rex to the gigantic long-necked Diplodocus.

But by the time the asteroid struck, killing them off, they were starting to decline, as they had ran out of space on Earth.

Las Vegas revives 'What happens here, stays here' campaign

  Las Vegas revives 'What happens here, stays here' campaign Three months after a mass shooting that killed dozens of concert goers on the Las Vegas strip, the gambling mecca has revived a lighthearted advertising campaign that once again paints the Nevada city as a place of reckless abandon and celebration. Following the Oct. 1 shooting, the Las Vegas Convention and Visitors Authority halted all campaigns that relied on the long-held motto "What Following the Oct. 1 shooting, the Las Vegas Convention and Visitors Authority halted all campaigns that relied on the long-held motto "What happens here, stays here." It was replaced with the hashtag #Vegasstrong, and a message of unity and recovery.

A new University of Reading research paper suggests dinosaurs may have been victims of their own success as they rose to world dominance 230 million years

The theory, outlined in the journal, Nature Ecology and Evolution, reconstructs the paths taken by the dinosaurs as they moved out of South America.

"They burst on to the scene and really quickly moved to all parts of the Earth," said Dr Chris Venditti of the University of Reading, a co-researcher on the study.

The dinosaurs were able to take advantage of a "blank canvas" left by the extinction known as the Great Dying, just before they appeared, he said.

They quickly spread across the devastated planet, taking up every opportunity to expand, with little competition for food, space or resources from other animals.

But towards the end of their reign, their progress slowed, as they became adapted to almost every habitat on Earth. Only avian dinosaurs survived to become the birds we know today.

  4 free agents who should ply their trades overseas out of spite We're well past the point of beating a dead horse about MLB teams' inactivity in the free-agent market this offseason, but it's understandable why top-tier players are miffed and holding out for better offers - especially just a few years removed from the Detroit Tigers handing pitcher Jordan Zimmermann a five-year, $110-million deal.

"They'd filled the Earth, there was nowhere to move to and they were really specialised in their habitat so they couldn't produce new species," said Dr Ciara O'Donovan of the University of Reading. "It would have been the final nail in the coffin for them apart from the birds."

The research is based on a statistical method to work out where every dinosaur and its ancestors existed, in three dimensional space, on the globe.

This gives a more complete picture than studying fossil evidence alone, which is patchy and incomplete.

But not all researchers are convinced by the idea that the dinosaurs were in decline before the asteroid hit Earth.

"Dinosaurs were continually diversifying all through the Cretaceous when the continents had split into smaller units," said Prof David Martill of the University of Portsmouth, who is not connected with the research.

"They were still diversifying at the end of the Cretaceous just before the meteorite impact hit. "

Winter Olympics superstar Marit Bjorgen says she quits .
Norway's legendary cross-country skier Marit Bjorgen, who won an eighth gold medal at last month's Winter Olympics, on Friday said she would call it quits at the age of 38. "I don't feel I have the motivation required to give 100 percent for another season, that's why I'm quitting," she told Norwegian public broadcaster NRK. She became the most successful athlete in Winter Olympic history on February 21 when she took bronze behind a stunning win for USA in cross-country skiing's women's team sprint free in Pyeongchang.
