Whether it is Rafael Nadal in tennis or Sourav Ganguly in cricket, some of the best sportspersons are left-handed. The advantage of being a southpaw may be more in a sport where a player has less time to react, according to a study by Florian Loffing, a sports scientist at the University of Oldenburg, Germany. The study appeared in the journal Biology Letters.

LEFT-HANDED LORD OF SPORTS

• Whether it is Rafael Nadal in tennis or Sourav Ganguly in cricket, some of the best sportspersons are left-handed. The advantage of being a southpaw may be more in a sport where a player has less time to react, according to a study by Florian Loffing, a sports scientist at the University of Oldenburg, Germany. The study appeared in the journal Biology Letters.

DOG HAS ITS DAY

• The image above shows 8,000-9,000 year-old etchings on rock faces in the Saudi desert, enhanced with digital tracings. These may be the earliest depictions of human-dog companionship. The series of etchings shows hunters using dogs to overwhelm prey such as gazelles before they killed them with arrows. With their pricked ears, angled chests and curly tails, the dogs resemble the modern breed of Canaan dogs.

CORAL GLORY

• A century ago, scientists who studied oceans wore glass helmets, dived in and sketched whatever passed by. Now they have mastered the art of creating 3D photomosaics out of thousands of pictures of corals deep in the ocean. The picture (above) by ecologists at Scripps Institution of Oceanography at the University of California, San Diego, shows how breaking and clustering help certain forms of coral survive on a highly competitive reef.
