Paul -- an octopus at the Sea Life public aquarium in Oberhausen, western Germany -- has so far correctly predicted the outcome of each of Germany's World Cup matches. On Tuesday, Paul contemplates Wednesday's match between Germany and Ghana. [larger view]
The World Cup and all the fanfare that surrounds it is truly amazing to experience. But perhaps strangest thing of all is that several zoos and aquariums in Germany have been asking some of their animals to predict the winners to the…

In 2002, ocean explorer Gale Mead was the first person to see and film the profusion of life 200 feet down on Salt Dome Seamount -- just 16 miles from where the BP oil well is now gushing out of control. Mead (daughter of oceanographer Sylvia Earle) describes the corals and fish she saw and the devastation that the oil is likely causing in a place that no other…

Perhaps you'd like to see what some of those creatures are that are being endangered by the oil spill in the Gulf of Mexico? This lovely video provides a glimpse of the "gelata": siphonophores, jellies and other soft, gelatinous marine animals that lack bones and brains, but nonetheless, comprise much of marine life. They are otherworldly creatures that glow in the dark…

This fascinating video captures a glimpse of the weird and wonderful animals that live in the aphotic zone. The aphotic zone (aphotic from Greek prefix á¼- + Ïá¿¶Ï "without light") is the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1% of sunlight penetrates. Consequently, bioluminescence is essentially the only light found in this zone. Most food comes from dead organisms sinking to…

Some 80 to 90 percent of undersea creatures make light -- and we know very little about how or why. Bioluminescence expert Edith Widder explores this glowing, sparkling, luminous world, sharing glorious images and insight into the unseen depths (and brights) of the ocean.

One night of passion and you're filled with a lifetime full of sperm with no need to ever mate again. As sex lives go, it doesn't sound very appealing, but it's what many ants, bees, wasps and termites experience. The queens of these social insects mate in a single "nuptial flight" that lasts for a few hours or days. They store the sperm from their suitors and use it to slowly fertilise their eggs over the rest of their lives. Males have this one and only shot at joining the Mile High Club and they compete fiercely for their chance to inseminate the queen. But even for the victors, the war…

Geneticist sequences own genome, finds genetic cause of his disease
If you've got an inherited disease and you want to find the genetic faults responsible, it certainly helps if you're a prominent geneticist. James Lupski (right) from the Baylor College of Medicine suffers from an incurable condition called Charcot-Marie-Tooth (CMT) disease, which…
edyong | March 4, 2010We've all heard about "beer goggles", the mythical, invisible eyewear that makes everyone else seem incredibly attractive after a few pints too many. If only beer had the reverse effect, making the drinker seem irresistibly attractive. Well, the good news is that beer does actually do this. The bad news is that the ones who are attracted are malarial mosquitoes.
Anopheles gambiae (the mosquito that transmits malaria) tracks its victims by their smells. By wafting the aromas of humans over thousands of mosquitoes, Thierry Lefevre found that they find the body odour of beer drinkers to be…
edyong | February 19, 2010It's not every day that you hear about spy missions that involve a lack of sex, but clearly parasitic wasps don't pay much attention to Hollywood clichés.
These insects merge the thriller, science-fiction and horror genres, They lay their eggs inside other animals, turning them into slaves and living larders that are destined to be eaten inside-out by the developing grubs. To find their victims, they perform feats of espionage worthy of any secret agent, tapping into their mark's communication lines, tailing them back to their homes and infiltrating their families.
Two species of…
edyong | February 9, 2010Mothers can teach their children much about the world, but some mothers can do it without ever meeting their young. Take the field cricket Gryllus pennsylvanicus. A female cricket isn't exactly a caring mother. Once she lays her eggs, she abandons them to their fate. But amazingly, she can also forewarn her young of the dangers they might face. If a pregnant female is exposed to a wolf spider, her experiences affect her unborn young. When they hatch, the baby crickets are more likely to freeze when they smell wolf spiders nearby.
If mothers sense a threat in their environment, there are…

Look into the oceans past the sharks, seals and fish and you will find the tiny phytoplankton. These small organisms form the basis of life in the seas but if their populations get to big, they can also choke the life from it by forming large and suffocating algal blooms.
The waters of San Francisco Bay have never had big problems with these blooms and if anything, scientists worried that the waters didn't have enough phytoplankton. All that changed in 1999, when the phytoplankton population started…

When our lives are in danger, some humans go on the run, seeking refuge in other countries far away from the threats of home. Animals too migrate to escape danger but one group - the pond-living bdelloid rotifers - have taken this game of hide-and-seek to an extreme.
If they are threatened by parasitic fungi, they completely remove any trace of water in their bodies, drying themselves out to a degree that their parasites can't stand. In this desiccated state, they ride the wind to safety, seeking fresh pastures where they can establish new populations free of any parasites.
