Fruit flies – fermented-fruit connoisseurs – are relentless party crashers

That fruit fly joining you just moments after you poured that first glass of cabernet, has just used its poppy-seed-sized brain to conduct a finely-choreographed search, one that’s been described for the first time by researchers at the University of … Continue reading

Aging erodes genetic control, but it’s flexible

In yeast at least, the aging process appears to reduce an organism’s ability to silence certain genes that need to be silenced. Now researchers at Brown University who study the biology of aging have shown that the loss of genetic … Continue reading

Protein interplay in muscle tied to life span

Brown University biologists have uncovered a complicated chain of molecular events that leads from insulin to protein degradation in muscles and significantly diminished life span in fruit flies. The new study in PLoS Genetics, which may have broad implications across … Continue reading

Engineered Flies Spill Secret of Seizures

Scientists have observed the neurological mechanism behind temperature-dependent — febrile — seizures by genetically engineering fruit flies to harbor a mutation analogous to one that causes epileptic seizures in people. In addition to contributing the insight on epilepsy, their new … Continue reading

UCLA Biologists Reveal Potential ‘Fatal Flaw’ In Iconic Sexual Selection Study

A classic study from more than 60 years ago suggesting that males are more promiscuous and females more choosy in selecting mates may, in fact, be wrong, say life scientists who are the first to repeat the historic experiment using … Continue reading

Newly Found Protein Helps Cells Build Tissues

University biologists have found a new molecule in fruit flies that is key to the information exchange needed to build wings properly. They have also uncovered evidence that an analogous protein may exist in people and may be associated with … Continue reading

Altered Gene Tracks RNA Editing in Neurons

*RNA editing is a key step in gene expression. Scientists at Brown University report in Nature Methods that they have engineered a gene capable of visually displaying the activity of the key enzyme ADAR in living fruit flies.* PROVIDENCE, R.I. … Continue reading
