...d documenting electrical pulses based on sex. They video recorded four pair of mating mormyrids (a feat in itself, since the species rarely breeds successfully in captivity) and identified nine common motor displays and 11 specific pulse sequences common to courtship and mating. "Knowing the electrical ...

He also recorded the sounds emitted from each moth, as well as the sounds made by the bats. All the bats quickly learned to avoid the noxious moths first offered t...

Palau's coral reefs show differential habitat recovery following the 1998 bleaching event

... averages. Using underwater digital video cameras, van Woesik and his team examined the rate of coral recovery at 13 different sites, and found that recovery rates increased over time; notably, sheltered bay areas, which suffered less in 1998, appeared to support recovery of outer-reef, "wav...

From the deep -- Researchers find new species of sea anemone

...olves a lot of high-tech equipment like underwater video cameras attached to remotely operated vehicles (ROVs). Deep sea ROVs are also equipped with robotic arms and suction devices that are used to collect species. "It's like a submarine that's manned from the surface," said Daly, who plans to head to ...

Flies don't buzz about aimlessly!

No-scalpel vasectomies by skilled surgeons may speed recovery

...echnique. Training was limited to an instructional video and one supervised procedure. Only one surgeon performed more than 10 no-scalpel vasectomies in the trial. The smaller study showed no difference in postoperative results between the two techniques, but this, review authors say, could have been d...
