Fruit fly's beating heart helps identify human heart disease genes

...t time the beating of the heart of a fruit fly, an insect the size of a grain of rice. The fly's heart is about the size of the period at the end of this sentence. After perfecting the new visualization technique, the researchers inserted into the fly genome a mutated gene that causes dilated cardiomyopath...

Jane Wang, professor of theoretical and applied mechanics at Cornell University, presented her research on flying systems and fluid dynamics today (Feb. 19) at the annual meeting of the American Association for the Adv...

New GM mosquito sexing technique is step towards malaria control, report scientists

"Female mosquitoes are responsible for spreading malaria, and also for damage to crops, but they are only able to breed once before dying. By forcing females to breed with sterile males, we can stop ...

Underlying cause of massive pinyon pine die-off revealed

"It was the drought - beetles don't get trees unless the trees are really water-stressed," Breshears said. Breshears, Neil S. Cobb, director of the Merriam-Powell Center for Environmental Re...

The shape of things to come: Morphology database going global

...Ronquist was working in Sweden in 1998 when he and insect specialists from the United States and Spain started MorphBank as a way to share the more than 1,000 microscopic photos they had taken in their comprehensive study of a group of parasitic wasps. The name of the database refers to the term morphology,...

Fruit fly research set to revolutionize study of birth defects

... "This is not a journal in the habit of publishing insect studies," notes biologist Dr. Virginia Walker, who co-authored the study. "The neat thing about this work is that fruit flies treated with this drug show 'birth defects' that are hauntingly similar to birth defects in human babies. Babies have bent...

K-State researchers study insects' immune system

Even though they will have some things in common, there's a lot to do for many lifetimes for people doing research on biochemistry in insects." Researcher...
