Protowings may have helped bird ancestors cover rough terrain
Biologists have long argued about how birds evolved the ability to fly, because it is not immediately evident what improvement in fitness would result from ancestral, partly evolved wings. view more (2006-05-01)
Pecan trees benefit from thinning technique
Pecan trees, like many fruit trees, have a tendency to bear fruit in cycles, producing a large crop in one or two years, followed by one or two years with little or no crop. view more (2009-11-04)
Dementia induced and blocked in Parkinson's fly model
Parkinson's disease is well-known for impairing movement and causing tremors, but many patients also develop other serious problems, including sleep disturbances and significant losses in cognitive function known as dementia. view more (2009-08-03)
Jefferson researchers uncover new way nature turns genes on and off
Peering deep within the cells of fruit flies, developmental biologists at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia may have discovered a new way that genes are turned on and off during development. view more (2006-12-28)
Study finds how organs monitor themselves during early development
How are you? In biological terms this question could involve a feedback loop that lets the body check in on itself and then act on that information view more (2006-08-28)
Protein protects against nerve degeneration
A protein called NMNAT protects against nerve cell degeneration in fruit flies and mice, said Baylor College of Medicine researchers in a report in the Public Library of Science Biology that appears online today. view more (2006-12-01)
Obesity genes revealed
A study of 228 women has revealed genetic variants responsible for body shape. Based on work in the fruit fly Drosophila melanogaster, research published today in the open access journal BMC Genetics identifies natural variation in the human LAMA5 gene as a key determinant of weight. view more (2008-08-11)
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...

Study links soft drinks and fruit drinks with risk for diabetes in African-American women
Researchers from Boston University's Slone Epidemiology Center have found that regular consumption of sugar-sweetened soft drinks and fruit drinks is associated with an increased risk for type 2 diabetes in African-American women. These findings appear in the July 28 issue of Archives of Internal Medicine. view more (2008-07-29)
Leishmaniasis parasites evade death by exploiting the immune response to sand fly bites
Cutaneous leishmaniasis, a disease characterized by painful skin ulcers, occurs when the parasite Leishmania major, or a related species, is transmitted to a mammalian host by the bite of an infected sand fly. view more (2008-08-15)
Mapping dynamic Polycomb group proteins during Drosophila development
The developmental passage from a ball of cells to a fruit-fly is a very complicated process involving both temporal and spatial regulation of genes and pathways. view more (2006-04-20)
Pomegranate fruit shown to slow cartilage deterioration in osteoarthritis
Pomegranate fruit extracts can block enzymes that contribute to osteoarthritis according to a Case Western Reserve University School of Medicine study published in the September 2005 issue of the Journal of Nutrition. view more (2005-09-01)
Study suggests new treatments for Huntington's disease
Working with fruit flies, researchers have discovered a new mechanism by which the abnormal protein in Huntington's disease causes neurodegeneration. view more (2008-01-10)
CSHL scientists discover a new way in which epigenetic information is inherited
Hereditary information flows from parents to offspring not just through DNA but also through the millions of proteins and other molecules that cling to it. view more (2008-12-01)
Fruit and vegetable intake in pregnant women reduces risk of upper respiratory tract infection
Boston University School of Medicine researchers (BUSM) have observed in a study of pregnant women that consumption of at least seven servings per day of fruits and vegetables moderately reduced the risk of developing an upper respiratory tract infection (URTI). view more (2009-07-09)
Flies on speed offer insight into the roles of dopamine in sleep and arousal
Methamphetamine, the drug of choice for long-distance truckers and college students pulling all-nighters, appears to do a similar trick for fruit flies, too. This finding is one of several in a new study that demonstrates a critical role for the neurotransmitter dopamine in the modulation of sleep, wake, and arousal states. view more (2005-07-12)
Reverse evolution in real-time
In his book, Wonderful World, Stephen Jay Gould writes about an experiment of 'replaying life's tape', wherein one could go back in time, let the tape of life play again and see if 'the repetition looks at all like the original'. view more (2009-01-12)
Study shows that soda consumption increases among adolescent girls as they get older
There are growing concerns over the effects of increased consumption of sodas and fruit drinks among adolescents in the United States. view more (2006-02-24)
Researchers find link between food odors and lifespan in fruit flies
Researchers hoping to learn why organisms tend to live longer if their intake of calories is restricted have made a startling discovery - in fruit flies, just the smell of food can have a negative effect on longevity. view more (2007-02-02)
Molecular research suggests shift needed in how some drugs are created
The first close-up look at a pro-inflammatory signaling molecule involved in immune response in mammals suggests that researchers "should rethink what they are doing" in creating drugs based on a fruit-fly model, scientists say. view more (2005-10-05)
