World indoor high jump champion Dimitris Chondrokoukis of Greece failed a doping test and has withdrawn from competition ahead of the Olympics. In a letter attributed to Chondrokoukis’ father, Kyriakos Chondrokoukis denied his son had taken the banned steroid stanozolol and asked for the B sample to be tested in a separate accredited lab. "The paradox of the use of such an easily detectable banned substance by a recent world champion who is under the microscope of doping control authorities, and on the eve of the Olympic Games, is blatantly obvious," Kyriakos Chondrokoukis wrote in the letter. "Against this paradox I will fight, we will fight, to answer and determine what exactly happened." Chondrokoukis was expected to be a contender for the gold medal after winning the indoor title this March. He joins over 100 other Olympic hopefuls to test positive ahead of London.
Injured cyclist Andy Schleck will make his comeback at Colorado's USA Pro Cycling Challenge next month, according to his team director Johan Bruynell. Schleck, who fractured his sacrum in a crash during the Criterium du Dauphine time trial, originally hoped to race in the Vuelta a España in August, but changed his plans after experiencing an unexpectedly tough recovery and deciding that he was unlikely to be fit enough to contend for the title. Schleck, 27, was one of the most high-profile riders in last year's inaugural Pro Cycling Challenge.
The opening ceremonies of the 2012 Olympics are still a few hours away, but a world record’s already been broken—by a legally blind man. Im Dong-Hyun, a 26-year-old South Korean archer, set a new 72-arrow record of 696 points earlier today, breaking his own world record by three points. Im has myopia, meaning he has 20/100 vision in his right eye and 20/200 vision in his left eye. This was only the seeding round, so the points get erased as the archers head into the single-elimination round, where seeding-round scores determine the matchups. Im, along with his countrymen Kim Bubmin and Oh Jin-Hyek, also set the 216-arrow team world record with a score of 2,087, breaking the previous record by 18 points. Im is ranked second in the world, behind American Brady Ellison, who finished 10th in the seeding round. The men’s team archery final is on July 28, and individual competition wraps up on August 3.

Big summer storms in the United States could be destroying the ozone layer, linking climate change and ozone loss in populated areas. In a study published online in the journal Science on Wednesday, researchers at Harvard University found that some summer storms send water vapor up into the stratosphere, setting off a series of chemical reactions with the remains of now banned CFCs, breaking down the ozone layer. “It’s the union between ozone loss and climate change that is really at the heart of this,” James G. Anderson, lead author of the study, said. Even moderate loss of ozone coverage can leave humans susceptible to skin cancer and eye damage from harmful ultraviolet rays.
