Researchers at the University of Geneva, Switzerland, demonstrate that the receptors that bind the toxin of this bacterium control how cell division is oriented Anthrax uses a receptor on the surface of cells to inject its lethal toxins. However, the physiological function of this receptor, named Anthrax Toxin Receptor 2a (Antxr2a), remained unknown until now. A team led by Marcos Gonzalez-Gaitan, a professor at the University of Geneva (UNIGE), Switzerland, in collaboration with Gisou van...

Several years ago, Prof. Michael Fainzilber and his group in the Biological Chemistry Department made a surprising discovery: Proteins thought to exist only near the cell nucleus could also be found in the far-off regions of the body's longest cells — peripheral nerve cells that extend processes called axons, reaching up to a meter in length in adult humans. These proteins, known as importins, have a well-studied role in the vicinity of the nucleus: They shuttle various molecules...

To solve a mystery, sometimes a great detective need only study the clues in front of him. Like Agatha Christie's Hercule Poirot and Arthur Conan Doyle's Sherlock Holmes, Tomomi Kiyomitsu used his keen powers of observation to solve a puzzle that had mystified researchers for years: in a cell undergoing mitotic cell division, what internal signals cause its chromosomes to align on a center axis? "People have been looking at these proteins and players in mitosis for decades, and no one ever...

Stowers researchers gain new insight into the chromosome separation process Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter cells. Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the...

Researchers at Delft University of Technology and the University of Basel have established a biomimetic nanopore that provides a unique test and measurement platform for the way that proteins move into a cell's nucleus. In the journal Nature Nanotechnology (June 19 - online), they report an artificial nanopore that is functionalized with key proteins which mimicks the natural nuclear pore. Upon testing the transport of individual proteins through the biomimetic pore, they found that most...

Dr. Joseph Glavy at Stevens Institute of Technology studies the smallest and most basic elements of life. The Assistant Professor of Chemical Biology runs the Glavy Lab, where advanced student scientists study the nuclear pore complexes (NPCs) in cells, observing the minutest mechanisms of life as they unfold during mitosis. The Glavy Lab's formal purpose is to study the NPC at the molecular level in the pursuit of the unknown or unexpected in the well-studied but not always well-understood...

Proteins that import structural material and that regulate the import determine cell size Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different species, but also in different types of cells in the same species and at different times during development. In addition, cancer cells are known to develop larger nuclei as they become more malignant. Screening for cervical...

Albert Einstein College of Medicine findings mark key advance in using microscopy to reveal secrets of living cells By constructing a microscope apparatus that achieves resolution never before possible in living cells, researchers at Albert Einstein College of Medicine  of Yeshiva University have illuminated the molecular interactions that occur during one of the most important "trips" in all of biology: the journey of individual messenger Ribonucleic acid (RNA) molecules from the...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
