Flies don't buzz about aimlessly!

.... Andy Reynolds says, "Our results with freely flying Drosophila appear to be the first reported example of searching behaviour that is both scale-free and intermittent. This suggests that these behaviours are not part of two different searching strategies, but rather represent a single very effective a...

Computer scientists join in search for ivory-billed woodpecker

...meras, Arecont Vision's AV3100s. "It's a fast, flying object," Song said. "And also, the shape of the object ?the shape of the bird ?isn't regular. It's deformable, and from the lighting conditions, it's very difficult to capture." The robot stores images of the birds it has recorded in the hard disk...

Neural bottleneck found that thwarts multi-tasking

... have to do in a very complex environment, such as flying a plane, and find out under what circumstances these tasks may be less vulnerable to dual-task interference," Dux added. For the record, neither Marois nor Dux use their cell phones while driving. "I'm Australian, and it's illegal there, so I'm...

New biochip helps study living cells, may speed drug development

..."We conducted research with the chip while we were flying in parabolas over the Gulf of Mexico, going from two times Earth's gravity to zero gravity again and again," he said. "There is absolutely no way this experiment could have been done without this chip." The current technology for analyzing cells' ...

Protowings may have helped bird ancestors cover rough terrain

...le to fly, chukars often use WAIR in preference to flying to gain elevated terrain, and exhausted birds always resort to WAIR. Dial and colleagues describe experiments showing that if the surface area of chukar wings is reduced by plucking or trimming the feathers, WAIR becomes less effective for climbing ...

Some people appear to be tracking to the earlier dusk of winter, causing a similar amount of misalignment but in the phase-advance direction. Symptom severity in SAD patients correlated with the misalignment in either direction. The treatm...

UCLA scientists strengthen case for life more than 3.8 billion years ago

...but in every case, the model has come through with flying colors." Manning agrees, saying he is confident the rocks contain evidence of ancient life, but "it's not a slam dunk." Why is there doubt? After more than 3.8 billion years, the rocks are severely damaged. "They have been folded, distorted, ...

Study finds how organs monitor themselves during early development

...kes ten days to go from embryo to larva to pupa to flying insect. The researchers looked at a larval development phase during which the ovary grows remarkably fast. In three days the number of primordial germ cells rises from twelve cells to 100 cells. The scientists started by looking at larvae with de...

Widespread elephant slaughter discovered in Chad

The second time we passed over I saw a guy and a horse and an assault rifle in the poacher's hands. The third time we flew over, this time only about 150 feet above the camp, I could see the man shootin...

U-M researchers take new approach to defeating Gram-negative bugs

Because Woodard suspected he might be flying in the face of conventional wisdom on bacteria, he solicited second opinions from the Borstel Research Center in Germany, which does a good deal of work on Gram-negative bacteria. Scientists there were initially skeptical, he said, but eventually, Uw...
