    A Nerve Impulse: From Point A to Point B

    The image at top is a scanning electron micrograph of a nerve ending. It has been broken open to reveal vesicles (orange and blue) containing chemicals used to pass messages in the nervous system.

    A nerve is an enclosed, cable-like bundle of axons (the long, slender projections of neurons) in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs. Vesicles are a basic tool used by the cell for organizing cellular substances. Vesicles are involved in metabolism, transport, and enzyme storage. They can also act as chemical reaction chambers.

    Neurotransmitters are endogenous chemicals that transmit signals from a neuron to a target cell across a synapse. In response to an electrical signal in the transmitting neuron, vesicles containing neurotransmitters fuse with the cell wall allowing the neurotransmitters to enter the synapse. Pictured in the image at the bottom, they move toward the receiving neuron and attach themselves to receptors (green), relaying the message. Extra neurotransmitters migrate back to the transmitting cell via reuptake transporters.

A Unique Fingertip Sensor Helps Robots Touch The World Around Them John Biggs, techcrunch.com
Robots need love, too. That’s why MIT researchers have added a touch-force sensor to the robotic Baxter, allowing him to register gentle caresses, tender hand-holding, and the sense the he is loved and in love. Okay, not really. But now Baxter, a…

  8. Verizon FiOS customer posts video that proves they throttle Netflix

    bitshare:

    imageIt’s been an ongoing debate for months, with each side pointing the finger at the other side. The issue? Verizon customers watching Netflix with slow playback speeds. The crux of the issue is that when streaming Netflix using Verizon, the speeds seem to be slower than normal causing buffering and a poor viewing experience.

    More bang for your buck

    We have dissected data from an international review site with profiles of 190,000 female prostitutes. The results show that gentlemen really do prefer blondes, who charge 11% more than brunettes. The scrawny look beloved of fashion magazines is more marketable than flab—but less so than a healthy weight. Prostitutes themselves behave like freelancers in other labour markets. They arrange tours and thanks to the internet, take bookings online, like gigging musicians.
