Xie Lab Demonstrates Dual Intrinsic and Extrinsic Control of Stem Cell Aging
The Stowers Institute's Xie Lab has published recent findings that reveal some of the factors underlying the aging of stem cells. view more (2007-10-11)
Targeting the dosage compensation complex
Three independent research papers in the April 1 issue of G&D detail the chromosome-wide binding of the Drosophila dosage compensation complex (DCC) to the single male X chromosome, shedding new light on the mechanism of DCC targeting. view more (2006-03-17)
Discovering what genes do the high-throughput way
Researchers at the Howard Hughes Medical Institute in Boston have developed a fast and systematic method that could make it easier to understand how cells from complex animals work. Their results, published this week in Journal of Biology, should inspire scientists to perform comprehensive screens of the fruit fly genome to find molecules that... view more... (2003-09-26)
Molecular basis for neurodegeneration in Ataxia telangiectasia
An upcoming paper from Dr. David Wassarman (University of Wisconsin School of Medicine and Public Health) in the May 1 issue of G&D lends new insight into the pathogenesis of neurodegeneration in Ataxia telangiectasia. view more (2008-04-15)
New tool isolates RNA within specific cells
A team of University of Oregon biologists, using fruit flies, has created a way to isolate RNA from specific cells, opening a new window on how gene expression drives normal development and disease-causing breakdowns. view more (2009-05-18)
Regulating the Nuclear Architecture of the Cell
An organelle called the nucleolus resides deep within the cell nucleus and performs one of the cell's most critical functions: it manufactures ribosomes, the molecular machines that convert the genetic information carried by messenger RNA into proteins that do the work of life. view more (2006-12-11)
UCLA Find Yields Further Insight Into Causes of Parkinson's Disease
In humans, a dearth of the neurotransmitter dopamine has long been known to play a role in Parkinson's disease. It is also known that mutations in a protein called parkin cause a form of Parkinson's that is inherited. view more (2007-02-02)
Brain region linked to fly slumber
Researchers at Northwestern University have pinpointed a brain area in flies that is crucial to sleep, raising interesting speculation over the purpose of sleep and its possible link with learning and memory. view more (2006-06-08)
Fly with brain tumor may shed light on cancer causing genes
A study showing how the expression of genes changes when the brain tissue of fruit flies becomes cancerous is published this week in BMC Genomics. As the function of many of these genes is conserved across evolution, the researchers expect their results will help us to understand why human brain tumors develop. The causes of brain tumor... view more... (2004-04-14)
Change in neurons' responsiveness marks newly formed sensory associations during learning
During our waking hours, our brains are inundated with sensory information that shifts from one moment to the next. view more (2005-11-08)
Tracing the formation of long-term memory
The formation of long-term memory in fruit flies can be demonstrated by the influx of calcium into cells called mushroom body neurons that occurs after special training that includes periods of rest, said researchers from Baylor College of Medicine (BCM) in a report that appears in the current issue of the journal Neuron. view more (2006-12-07)
Using insects to test for drug safety
Insects, such as some moths and fruit flies, react to microbial infection in the same way as mammals and so can be used to test the efficiency of new drugs, thereby reducing the need for animal testing. view more (2009-09-08)
Over £11M cash injection for research in genomics
The grants represent a major investment in "genomics" research, i.e. in understanding more about what genes and their products do in cells, and how they are naturally regulated and respond to internal and external stimuli to influence a cell's metabolism and behaviour. Key technologies are the microarrays * and resources for studying the protein... view more... (1999-10-12)
K-State contributions to red flour beetle genome sequencing featured in March 27 issue of Nature
Most of us hate to find the red flour beetle living happily in the flour sack in our pantries. But for several scientists at Kansas State University, and many others throughout the world, this pest of stored grain and grain products is the best organism for studying genetics. view more (2008-03-24)
Pesky fruit flies learn from experienced females: Study
A common household nuisance, the fruit fly, is capable of intricate social learning much like that used by humans, according to new research from McMaster University. view more (2009-09-17)
Ume'å scientist presents discoveries about natural immunity in Science
A team including scientists at UCMP (Ume'å Center for Molecular Pathogenesis), a research unit at Ume'å University, shows in last week's issue of the journal Science that the protein PGRP-LC plays a crucial role in so-called innate immunity. Professor Dan Hultmark, post-doctoral fellow Svenja Stöven, and doctoral candidate Thomas... view more... (2002-03-04)
Similar brain chemicals influence aggression in fruit flies and humans
Serotonin is a major signaling chemical in the brain, and it has long been thought to be involved in aggressive behavior in a wide variety of animals as well as in humans. Another brain chemical signal, neuropeptide Y (known as neuropeptide F in invertebrates), is also known to affect an array of behaviors in many species, including territoriality... view more...

Circadian surprise: A heat sensor for body-clock synchronization
New research on the fruit-fly brain points to a possible mechanism by which temperature influences the body clock, according to scientists from Queen Mary, University of London. view more (2009-10-30)
Cells, dyes and videotape: Online scientific methods journal incorporates multimedia
Observing the microscopic mysteries of embryos, cells, and chromosomes is feasible with advanced live imaging technologies. view more (2006-11-06)
Genetic Surprise Confirms Neglected 70-Year-Old Evolutionary Theory
Biologists at the University of Rochester have discovered that an old and relatively unpopular theory about how a single species can split in two turns out to be accurate after all, and acting in nature. view more (2006-09-08)
