LCD Projector Controls Tiny Worms
ATLANTA, Jan. 24, 2011 — Researchers are using inexpensive components from ordinary LCD projectors to control the brain and muscles of tiny organisms, including freely moving worms. Red, green and blue lights from a projector activate light-sensitive microbial proteins that are genetically engineered into the worms, allowing the researchers to switch neurons on and off like light bulbs and turn muscles on and off like engines. Georgia Tech graduate student Jeffrey Stirman, associate professor Hang Lu, and...
Fruit Flies and the Age of Anti-Intellectualism
Jun 29, 2010 — Scientific research has lately faced an intractable challenge to its legitimacy. It’s not a new threat. The research community has wrestled with it in the past. And it will almost certainly encounter it again. In his 1964 Pulitzer...
Light offers read-and-write access to brain cells
OXFORD, UK – A new set of methods allows experimental interaction with biological systems composed of many interacting cell types, such as neural circuits in the brain. Researchers at the University of Oxford have used light to manipulate the memories of fruit...
Lasers Twist Fly Memories
OXFORD, England, Oct. 19, 2009 -- Light has been used to manipulate the memories of fruit flies, allowing them to learn from mistakes they never made and scientists to pinpoint the nerve cells that regulate such actions. The work could provide valuable information about how memories...
CNTs Glow in Live Fruit Flies
HOUSTON, Sept. 25, 2007 -- The first optical images of carbon nanotubes inside a living organism have been captured using a laser, a custom microscope, a camera and hungry fruit flies. It is hoped that the technique will prove useful in disease diagnosis. Rice University...
Simple Protein Key to Insect Eye Evolution
CHEVY CHASE, Md., Oct. 5, 2006 -- Researchers have found that mutations in a single structural protein can determine whether an insect develops the highly organized, light-harvesting eye that flies have, or the optically simpler compound eye of a beetle or bee. In their...
Hot Flies Produce Cool Results
ITHACA, N.Y., Sept. 25, 2006 -- Using multiphoton fluorescence microscopy, researchers have for the first time watched chromosomes change form to activate their genes to synthesize key proteins in fruit fly cells. The advance could be a significant step toward understanding the...
