Diego López faces the challenge that resists him

first_imgDiego López will live today his sixth duel against Barcelona with the blue and white shirt and in the previous five he has received 14 goals. The last in Cornellà-El Prat, last year, does not keep excessive good memories because Espanyol fell 0-4, Leo Messi scored two goals and is scored a goal in his own door. Diego López will try to leave history behind a Barcelona that is choking him today. In addition to having scored 38 goals, it is the second set against which he has won the most losses (11). Only Madrid has won more times (12). Diego López, who ends the contract at the end of this season and is now free to negotiate with any other team, is focused solely on helping Espanyol seal the salvation. And everything happens to show its best version. Leaving his goal to zero against Barcelona is something that would give him wings at the motivational level and, in addition, catapult his team. Of course, it is a subject that has pending before the Catalans. He has faced in Primera in 17 games and the balance is two wins (with Villarreal and Real Madrid), four draws and 11 losses. And in them he only left his goal zero once. It was with Villarreal, the 2011-12 season (0-0). With the yellow set he wore, but he also had to suffer the greatest culé punishment because that same course suffered a 5-0, on day 2, at Camp Nou. Diego López has a challenge today against Barcelona: leaving his goal to zero. The Espanyol goalkeeper suffers when he faces the Catalans, and that is the team that has scored the most goals in Primera (38). Diego wants to claim, dry Barça, and yesterday, through his Twitter account, he was in charge of putting the spotlight on today’s clash: “Maximum difficulty, total motivation. It’s time to be together. Come on, Espanyol“he said.last_img read more

‘Can opener’ cats?

first_imgPaleontologists have long wondered how extinct saber-toothed cats like Smilodon used their lengthy fangs when tackling and chewing prey. For decades, researchers thought the cats first bit into their prey with their lower jaws and then used strong neck muscles to roll their head forward and downward to power a bite. But that technique probably wouldn’t work, a pathologist now suggests, because rotation of the head alone wouldn’t help close the jaws. At the full gape needed to get its teeth around prey, he notes, the cat’s jaw muscles wouldn’t have good leverage and bite forces would be relatively weak. Instead, he proposes, a cat first jammed its lower jaw against its prey (top image), similar to the previous model. But then the creature stood up on its forelimbs (bottom image). That motion increased leverage by both raising the base of the neck and rotating the head forward, which powered the fangs into the prey. That motion is comparable to punching a hole in a can with an old-fashioned can opener (the kind that makes a triangular hole on the can’s lid), he proposes today in PLOS ONE. Computer simulations might confirm whether the new model is plausible, the pathologist suggests.last_img read more
