Pleasing plant shapes explained by new computer model

...lant that is to the world of botany what the fruit fly and white mouse are to zoology. The scientists believe their model will enhance biological experiments by providing a tool botanists can use to complement and interpret their traditional laboratory experiments. It also promises to lead to accurate m...

Scientist uses dragonflies to better understand flight

... size and feasibility remain. "To hover well or to fly for a long time is hard, especially at slow speeds," she said. "Power is limited. So finding these efficient motions is very important." Still, Wang's work moves researchers a step closer to building such a machine. "I want to build insects on a co...

Largest study of human 'interactome' reveals a novel way

...25,000 human, 16,000 yeast, 5,500 worm, and 25,000 fly protein-protein interactions showed that, among these more than 70,000 links, only 16 were common to all four species. Researchers say this low level of interactome overlap among species was surprising. It showed that current rapid-testing method...

Researchers unlock how cells determine their functions

...epigenetic activators (such as Ash1 from the fruit fly Drosophila), bind to their target DNA and activate genes that determine what function a cell will have in the body. "The fact that these epigenetic activators, such as Ash1, turn on the expression of specific target genes has been known for some ti...

UCSD study finds anthrax toxins also harmful to fruit flies

Researchers develop new method to help find deadly malaria parasite's Achilles heel

... our earlier research showed that yeast, worm, and fly have hundreds of both conserved proteins and prote...the known protein interactions in yeast, worm, and fly represent only 20 percent of the total interactions and some of the reported interactions may be err...

Past experience of pheromones induces dominant courtship behavior in fruit flies

...chester, United Kingdom. When an adult male fruit fly encounters a young male fly, he will actively court the younger individual, sometimes becoming aggressive. These young males that have encountered older flies will go on to similarly dominate other adult males that had encountered only young flies--s...

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

...that the two instruments were originally chosen to fly because of their ability to measure stratospheric ozone, but were also selected in order to investigate the amount of useful information that could be retrieved from the troposphere. "The instruments are now being used to monitor a significant numb...

Wright bros. upstaged! Dinos invented biplanes

...ui used a two-level, biplane wing configuration to fly from tree to tree in the early Cretaceous. Among the evidence for the early biplane is that Microraptor had unmistakable flight feathers on its hind limbs as well as on its wings, says Chatterjee, a distinguished professor at Texas Tech University in...

The earliest animals had human-like genes

... perspective, it was long assumed that the simpler fly genes would be more ancient. The current study reveals the opposite: early animals already had a lot of introns, and quickly-evolving species like insects have lost most of them. To discover what early animals were like, scientists usually compare t...

For that matter, this ability to detect species in earlier stages of development could benefit ecologists in their work as well, Meyer said.
