Important Features Of Natural Pores Copied By Man-made pores
2012-07-17 10:57:46

Inspired by nature, researchers design tiny, synthetic pores that mimic important features of cellular ion channels and other molecular channels Inspired by nature, an international research team has created synthetic pores that mimic the activity of cellular ion channels, which play a vital role in human health by severely restricting the types of materials allowed to enter cells. The pores the scientists built are permeable to potassium ions and water, but not to other ions such as...

Tiny pores, or channels, embedded in cell membranes are critical to the healthy functioning of cells. Charged atoms, or ions, move through these channels to generate the electrical signals that allow cells to communicate with one another. New research at Washington University School of Medicine in St. Louis unveils some of the inner workings of certain channels involved in regulating electrical signals in nerve cells, relaxing muscle cells and “tuning” hair cells in the inner...

Brown 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 problems such as cleft lip, or premature ovarian failure. As they work together to form body parts, cells in developing organisms communicate like workers at a construction site. The discovery of a new signaling molecule in flies by Brown...

A new study in the Journal of General Physiology (http://www.jgp.org) provides fresh insight into voltage-gated channels–transmembrane ion channels that play a critical role in the function of neuronal and muscle tissue. Voltage-gated ion channels underlie signaling of most electrically active cells. These important ion channels have long challenged physiologists with the question of how membrane voltage drives the structural transitions between closed and open states. For more than...

Potential mechanism for dazzling blue flashes of light in oceans identified It has long been known that distinctive blue flashes--a type of bioluminescence--that are visible at night in some marine environments are caused by tiny, unicellular plankton known as dinoflagellates. However, a new study has, for the first time, detailed the potential mechanism for this bioluminesence. The study, which was partially funded by the National Science Foundation, is reported by Susan Smith of Emory...

Image 1 - Biochemical Cell Signals Quantified For The First Time

  Just as cell phones and computers transmit data through electronic networks, the cells of your body send and receive chemical messages through molecular pathways. The term “cell signaling” was coined more than 30 years ago to describe this process. Now, for the first time, scientists have quantified the data capacity of a biochemical signaling pathway and found a surprise — it´s way lower than even an old-fashioned, dial-up modem. “This key...

When It Comes To Speaking Out, Cells Wait Their Turn

  Revealing how cells communicate, Tel Aviv University research could lead to new cancer drugs and more Cell communication is essential for the development of any organism. Scientists know that cells have the power to "talk" to one another, sending signals through their membranes in order to "discuss" what kind of cell they will ultimately become – whether a neuron or a hair, bone, or muscle. And because cells continuously multiply, it's easy to imagine a cacophony of...

By altering the genetic makeup of normally "unexcitable" cells, Duke University bioengineers have turned them into cells capable of generating and passing electrical current. This proof-of-concept advance could have broad implications in treating diseases of the nervous system or the heart, since these tissues rely on cells with the ability to communicate with adjacent cells in order to function properly. This communication is achieved through the passage of electrical impulses, known as...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
