The ability of the eye of a fruit fly (Drosophila melanogaster) to respond to light depends on a delicate ballet that keeps the supply of light sensors called rhodopsin constant as photoreceptors turn on and off in response to light exposures, said researchers from Baylor College of Medicine (www.bcm.edu) and the Jan and Dan Duncan Neurological Research Institute (http://www.nri.texaschildrens.org/) at Texas Children's Hospital in an article that appears online in the journal PLOS Biology...

A collaboration by an international consortium of researchers led by scientists at Baylor College of Medicine and the Montreal Neurological Institute of McGill University have linked the discovery of a mutation in a mitochondrial gene in fruit flies that causes the loss of neurologic function (a neurodegenerative set of characteristics or phenotype) and a progressive recessively inherited ataxia or neurodegenerative disorder in humans. A report in the online, open access journal PLoS...

A collaborative study by scientists at Baylor College of Medicine (BCM) and the Montreal Neurological Institute of McGill University, and published March 20 in the online, open access journal PLoS Biology, has discovered that mutations in the same gene that encodes part of the vital machinery of the mitochondrion can cause neurodegenerative disorders in both fruit flies and humans. Vafa Bayat in Dr. Hugo Bellen's lab at BCM, examined a series of mutant fruit flies for defects leading to...

The transmission of information from one neuron to the next is an unseen intricate ballet. Tiny vesicles "“ bubbles containing the chemical neurotransmitters that make information exchange possible"”travel to the tip of neurons (synapses), where they fuse with the cell's membrane in a process called exocytosis. The extra membrane is then captured in a process called endocytosis and recycled to form a new vesicle to enable the next cycle of release. The two processes, exocytosis...

As part of the intricate ballet of synaptic transmission from one neuron to the next, tiny vesicles "“ bubbles containing the chemical neurotransmitters that make information exchange possible"”travel to the tip of neurons (synapses), where they fuse with the cell's membrane (a process called exocytosis). The extra membrane is then captured in a process called endocytosis and recycled to form a new vesicle to enable the next cycle of release. Most important, exocytosis must be...

Recycling is a critical component in the process of transmitting information from one neuron to the next, and a large protein called Tweek plays a critical role, said an international consortium of researchers led by Baylor College of Medicine (www.bcm.edu) in a report in the current issue of the journal Neuron.Fruit flies that lack the protein, named for the over-caffeinated character in the cartoon South Park, shake in a hyperactive manner, said Dr. Hugo Bellen, professor of molecular and...

"“ Notch signaling helps determine the fate of a number of different cell types in a variety of organisms, including humans. In an article that appears in the current issue of Nature Cell Biology, researchers at Baylor College of Medicine report that a new finding about the Notch signaling pathway in sensory organ precursor cells in the fruit fly could explain the mystery behind an immunological disorder called Wiskott-Aldrich syndrome."This finding provides a model for how Wiskott...

Using a specially adapted tool called P[acman], a collaboration of researchers led by Baylor College of Medicine has established a library of clones that cover most of the genome of Drosophila melanogaster (fruit fly) and should speed the pace of genetic research.In a report in the current online issue of the journal Nature Methods, Dr. Hugo Bellen (http://flypush.imgen.bcm.tmc.edu/lab/), a professor of molecular and human genetics at BCM and a Howard Hughes Medical Institute investigator,...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
