Researchers restore vision to mice by unlocking retina’s neural code

By - August 20, 2012 1 Picture
Retinal prostheses such as the Argus II, Bio-Retina and the Retina Implant AG microchip all work – more or less – by stimulating the retina’s ganglion cells with light-induced electrical signals. The images produced in the patient’s visual cortex tend to be quite rudimentary, however. This is partially because the rate at which the signals are sent isn’t the same as the rate of neural impulses normally produced by a retina. Now, researchers have deciphered the neural code used by mouse ganglion cells, and used it to create a prosthesis that reportedly restores normal vision to blind mice. They have additionally deciphered the neural code of monkeys, which is close to that used by humans, so a device for use by blind people could also be on the way. Read More

Easter Island drug improves learning and memory in mice of all ages

By - July 1, 2012 1 Picture
Rapamycin, a bacterial product first discovered in a soil sample from Easter Island – also known as Rapa Nui, hence the name – is an immunosuppressant drug used to prevent rejection in organ transplants that has now been found to enhance learning and memory in young and old mice alike. Researchers at the School of Medicine at The University of Texas (UT) Health Science Center San Antonio made the discovery while looking for a way to prevent the decline in cognitive skills that comes with age.

Peoples' immune systems can now be duplicated in mice

By - March 16, 2012 1 Picture
Because everyone’s immune system is different, it’s impossible to predict with absolute certainty how any given person will react to a specific medication. In the not-too-distant future, however, at-risk patients may get their own custom-altered mouse, with an immune system that’s a copy of their own. Medications could be tried out on the mouse first, and if it showed no adverse reactions, then the person could receive them. If the person had an autoimmune disease, the mouse could also provide valuable insight into its treatment. A team led by Columbia University Medical Center’s Dr. Megan Sykes has recently developed a method of creating just such a “personalized immune mouse.” Read More

Scientists destroy tumors in mice using light therapy

By - November 13, 2011 1 Picture
Besides surgery, chemotherapy and radiation are the foundation of modern day cancer treatment. Although effective, these therapies often have debilitating and damaging side effects. But scientists at the National Cancer Institute in Bethesda, Maryland have been experimenting with a new form of therapy using infrared light to kill cancer cells and shrink tumors without damaging healthy tissue.

Fluorescent nanotubes used for imaging of internal organs

By - June 25, 2011 1 Picture
Mice are frequently used as lab models when testing new drugs, and fluorescent dyes are sometimes injected into their bodies so that researchers can better see how those drugs are progressing through their systems. Unfortunately, the pictures obtained in this process start to become murky when imaging anything more than a few millimeters beneath the skin. Scientists from Stanford University have now devised a system that utilizes fluorescent carbon nanotubes to produce clear color images of organs that are located centimeters within a mouse's body.

Prototype explosives-detection system utilizes live 'sniffer mice'

By - February 28, 2011 2 Pictures
Mice ... they may nibble our food, poop in our cupboards, and make us go "eek," but they may also someday keep us from getting blown up. Before they can do that, however, Israeli tech company BioExplorers has to get its mouse-based explosives detection system out of the prototype stage and into production. If it ever does see the light of day, then people at airports, arenas, and other high terrorism-risk areas may routinely be getting a sniff-down by containers of live rodents. Read More

Using satellite imagery to track 'killer' mice from space

By - February 16, 2011 2 Pictures
Directly tracking disease-carrying mice from space would seem to be a tall order – and even without knowing the full capabilities of military satellites, I suspect the ability to do so is still a couple of years off yet. But researchers at the University of Utah have come up with an indirect way of tracking rodents by using satellite images to monitor surges in vegetation that boost mouse populations. Such a method could help forecast outbreaks of rodent-borne illnesses worldwide by allowing the creation of risk maps that show when and where outbreaks are likely to occur. Read More

Light stimulation could restore movement to paralyzed limbs

By - September 29, 2010 1 Picture
In a study that could eventually restore movement to humans’ paralyzed limbs, researchers at California’s Stanford University have used light to induce muscle contractions in mice. A gene derived from algae was inserted into the mice, encoding a light-sensitive protein which adhered to their nerve cell surfaces. Scientists then placed an “optical cuff” lined with tiny, inwards-facing LEDs around the mice’s sciatic nerves. By penetrating those nerves with brief, high-intensity bursts of blue light, they were able to produce muscle contractions similar to those that would occur naturally. The technology is called “optogenetics.” Read More

Sight restored in blind mice

By - June 25, 2010 1 Picture
The classic nursery rhyme Three Blind Mice might need to be rewritten thanks to researchers from the Friedrich Miescher Institute (FMI) and the Institut de la Vision in Paris. Using gene therapy, the scientists have have restored sight in mice by repairing the function of cone photoreceptors made defective by a genetic eye condition. Read More

Aigo Glide mouse - effortless control at your fingertips

By - January 12, 2010 9 Pictures
Recent developments in the war on repetitive strain injury have seen swiveling mice and applicable gel pads in an effort to make the everyday user experience a more comfortable one. Appearing at CES this year was another take on the ubiquitous peripheral, the Aigo Glide mouse. Designed to offer ease of use and minimal strain, the lightweight mouse features indentation for fingertips and side scrolling wheels, while the USB cord and connection even tuck away around and under the mouse for easy storage.
