Research will be presented on Sunday, Dec. 15, during ASCB annual meeting in New Orleans Resolving a fundamental question in cell biology and showing off the powers of new high-resolution 3-D imaging, NIH scientists have discovered where the Golgi apparatus, which sorts newly synthesized proteins for transport inside and outside the cell, goes when it disassembles during cell division, according to research to be presented on Sunday, Dec. 15, at the American Association for Cell Biology...

The outer membrane of bacteria contains many proteins that form tiny pores. They are important for absorbing nutrients and transmitting signals into the cell. The research group of Sebastian Hiller, Professor of Structural Biology at the Biozentrum, University of Basel, has now shown for the first time at atomic resolution, that these pore proteins are transported in an unstructured, constantly changing state to the outer bacterial membrane. This landmark study was recently published in the...

3D movie at ℠ultraresolution´ shows how cell´s machinery bends membrane inwards Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have combined the power of two kinds of microscope to produce a 3-dimensional movie of how cells ℠swallow´ nutrients and other molecules by engulfing them. The study, published today in Cell, is the first to follow changes in the shape of the cell´s membrane and track proteins thought to...

Opening up a new door in synthetic biology, a team of researchers has developed a microfluidic device that produces a continuous supply of tiny lipid spheres that are similar in many ways to a cell's outer membrane. "Cells are essentially small, complex bioreactors enclosed by phospholipid membranes," said Abraham Lee from the University of California, Irvine. "Effectively producing vesicles with lipid membranes that mimic those of natural cells is a valuable tool for fundamental biology...

A new technique developed by researchers at RIKEN has clarified the location and dynamics of specific metabolites in a single cell of the alga Chara australis. The findings reveal that these metabolites are regulated and fluctuate under stress conditions, providing insight into previously-unknown functions of the vacuole in cellular processes. Metabolites, the intermediates and products of chemical reactions that sustain all living organisms, play a central role in cellular processes...

EMBL discovery could yield evolutionary insights and new model organism Although they are present almost everywhere, on land and sea, a group of related bacteria in the superphylum Planctomycetes-Verrucomicrobia-Chlamydiae, or PVC, have remained in relative obscurity ever since they were first described about a decade ago. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have discovered that these poorly-studied bacteria possess proteins thought to exist...

New Haven, Conn. "“ Researchers at Yale have brought to light a mechanism that regulates the way an internal organelle, the Golgi apparatus, duplicates as cells prepare to divide, according to a report in Science Express. Graham Warren, professor of cell biology, and his colleagues at Yale study Trypanosoma brucei, the parasite that causes Sleeping Sickness. Like many parasites, it is exceptionally streamlined and has only one of each internal organelle, making it ideal for studying...

Astrobiology Magazine -- A team of biologists from the University of California, Riverside has used chemical genomics to identify novel compounds that affect the ability of plants to alter their direction of growth in response to gravity, a phenomenon known as gravitropism. The researchers screened a library of 10,000 small molecules, the practice is known as chemical genomics, to identify those that could positively or negatively affect gravity's effect on plant growth, which is closely...

  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
