Bats use touch receptors on wings to fly, catch prey, study finds

Bats have an "ear" for flying in the dark because of a remarkable auditory talent that allows them to determine their physical environment by listening to echoes. But an Ohio University neurobiology professor says bats have a "feel" for it, too. John Zook's studies of bat flight...

Sahara's edge studied from ground, air and space to improve water management

...ew sensors." At the same time as the Dornier was flying out of Tunisia's Djerba International Airport, Tunisian and European participants on the ground gathered information including the size and position of fields, local topography, the soil surface characteristics and vegetation type, distribution and p...

Ancient trans-Atlantic swarm brought locusts to the New World

...unlikely hypothesis is that while the locusts were flying across, as their brethren died and landed in the ocean, they formed huge floating mats of dead locusts," says Lovejoy. "The other locusts would land on these mats, rest and feed on the dead bodies, then take off and keep flying." Another possibility ...

NIAID researchers show how promising TB drug works

...oved versions of the drug." "Previously, we were flying blind in trying to optimize PA-824 in a rational way because we didn't know which M. tb protein was the target of PA-824's action," says NIAID scientist Clifton Barry, III, Ph.D., who headed the research team. In preclinical testing, PA-824 showe...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...'s Principal Investigator. "Before SCIAMACHY was flying we previously retrieved NO2 data from its precursor instrument, GOME on ESA's ERS-2 mission. Although GOME had lower resolution, the article shows that China's nitrogen dioxide retrievals from the two instruments overlap seamlessly. "What the combi...

Researchers reveal secrets of flying snakes

It seems size does matters after all. But for flying snakes, smaller is better, according to University...ists described the effects of size and behavior of flying snakes, and found that the smaller animals were better gliders. "Despite their lack of wing-like ap...

Alarm pheromone causes aphids to sprout wings

...esene, they could in theory manipulate aphids into flying away. However, aphids were shown to react mainly to the frequency of pheromone release and not the actual quantity present, possibly to avoid manipulation by plants. Thus, to reduce damage caused by aphids, the major insect pests in Europe, it may p...

Finding hidden invaders in a Hawaiian rain forest

...ineers from the NASA Jet Propulsion Laboratory are flying an upgraded version of the AVIRIS airborne spectrometer on a more nimble Twin Otter turboprop aircraft, not only to find invasive species, but to develop the next generation of ecosystem monitoring capabilities. On Kilauea Volcano, the native Metros...

In the migratory marathon, parasitized monarchs drop out early

These results, published in the March issue of Ecology Letters, could explain why parasite infections are much lower in migratory monarch populations compared to year-round residents that do not migrate. Habitat loss at overwi...
