Input: Consider Input: And with a mangled racket and plenty of kicking and screaming  including a couple of arguments with the chair umpire  then a postmatch parting shot at a line judge Safin called "a little bit too blind."
 Safin used to rant about disliking tennis on grass  and he once complained about the high price and low quality of food at the players' restaurant at the All England Club. Well  he doesn't have to worry about any of that again after bowing out in his final Wimbledon with a 6-2  3-6  7-6 (4)  6-4 loss to Levine.
 After confirming this would be his last appearance at the grass-court Grand Slam tournament -- Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
 "He's an amazing player  and I'm still kind of feeling weird right now that I just beat Safin  because I've always watched him play on TV " said Levine  who turned pro in 2007. "I just kind of went out there with nothing to lose and played some good tennis."
 Levine was a teen when Safin burst onto the scene as a brash  big-hitting 20-year-old who knocked off Sampras to win the U.S. Open.
 "I really had to ... focus on playing against the ball and not worrying about  'Oh  wow  I'm playing against Marat Safin on the other side of the court '" Levine said. "Because then things could have gotten a lot more interesting."
 As is his wont  Safin made things interesting enough. In the early going  he broke his racket by spiking it on the court.
 Leading 4-3 in the third-set tiebreaker  Safin hit a shot near a line that was ruled out. Afterward  Safin said: "Thanks for the guy who made the call. I want to say hello to him. Too bad that he was a little bit too blind."
 In the fourth set  Safin told the chair umpire he could check for chalk on the ball to confirm a call. Rebuffed  Safin added: "So all players are stupid?"
 Safin reached at least the semifinals at all four majors  including at Wimbledon last year  but he has been criticized for not living up to the potential stored in his 6-foot-4 (1.93-meter) frame -- about 7 inches (18 centimeters) taller than Levine.
 "In the history of tennis  everybody's an underachiever " Safin said. "Agassi should have been winning  I don't know  15 Grand Slams. Sampras should have been winning 20 Grand Slams. Federer should be winning -- already should have 25."
 "I should probably have (won) a couple of more " he said  "but I'm pretty satisfied with what I did."

Input: Consider Input: Goldsmith Akis Goumas  is currently attempting to replicate the stone in hard wax or burnt clay to understand the movements  shape and size of the handheld tools used.
In tracing the tool marks on the sealstone   Goumas  speculates that the craftsman may have used a rotating wooden lathe with a sharp edge to engrave the stone.
 He  thinks one artisan did the basic  three-dimensional engraving while another completed the secondary work.
"It isn't one craftsman's work because we can see different qualities of dexterity in the synthesis "  he  told CNN over email.
While  Goumas  may soon have answers as to how  it  was fashioned 3 500 years ago  Stocker says we will probably never know how  it  came into the Griffin Warrior's possession.

Input: Consider Input: Last winter   Dante de Kort -- an eight-year-old boy who lives in central Arizona --  found a dead collared peccary  a wild pig-like animal  near  his  house.  He  set up a motion-controlled camera nearby  and over the next ten days  was surprised to discover footage of the peccary's herd returning to visit their dead herd-member  over and over.
When  he  wrote up  his  findings in a school science-fair presentation  it caught the attention of local biologist Mariana Altricher. It looked like the wild pecarries were in mourning  which was surprising: Scientists have seen grief-like behavior in animals like elephants  dolphins and primates  which are known for their high level of intelligence. But never in these creatures  as National Geographic reports:
Having studied the social  pig-like mammals for years  Altrichter knew how tightly bonded peccaries could be. But she'd never witnessed herd members return to a body repeatedly ... “It was pretty amazing because it wasn’t just an immediate reaction and then they moved on—it went on for 10 days ” says Altrichter  chair of the International Union for Conservation of Nature’s Peccary Specialist Group. [snip] In the videos  the peccaries pay close attention to the body  nuzzling  biting  sniffing  and staring at it. They slept next to the carcass  and even tried to lift it by wedging their snouts under the body and pushing upward. And when a pack of coyotes approached their fallen peer  the herd chased them away. “It really surprised me that they would stand up to the coyotes ” says  de Kort   noting the peccaries were outnumbered.
Altricher used the video evidence to write a scientific paper -- "Collared peccary (Pecari tajacu) behavioral reactions toward a dead member of the herd" -- that lists  de Kort  as its lead author.
