Scientists reverse Alzheimer’s-like symptoms in mice

Scientists have discovered a way of counteracting the proteins that cause Alzheimer's-like symptoms including memory loss. In mice, at least. Whereas other treatments have focused on beta-amyloid clumps (which the University of Michigan recently disc...

Super-fast camera records light-based ‘sonic booms’

Scientists have suspected that light can create its own conical wakes, like a sonic boom, but how do you capture something that happens so quickly? With a very fast camera, naturally. Washington University in St. Louis has recorded these photonic sho...

Kinect sensors could lead to safer X-rays

You don't want to stand in front of an X-ray machine for any longer than necessary, and scientists have found a clever way to make that happen: the Kinect sensor you might have picked up with your Xbox. Their technique has the depth-sensing camera m...

LED implants could ease your pain

One day, eliminating pain may just be a matter of flicking on a light. Scientists have shown that you can implant LEDs that stop neurons from firing and cut out pain reception. The current technique (tested in mice) requires altering the neurons'...

Universities inject neuron-sized LEDs to stimulate brains without a burden (video)

Universities inject neuronsized LEDs to light up brains for study without the headaches

Existing methods for controlling brain activity tend to skew the results by their very nature -- it's difficult to behave normally with a wad of optical fibers or electrical wires in your head. The University of Illinois and Washington University have developed a much subtler approach to optogenetics that could lift that weight from the mind in a very literal sense. Their approach inserts an extra-thin ribbon into the brain with LEDs that are about as big as the neurons they target, stimulating deeper parts of the mind with high precision and minimal intrusion; test mice could act as if the ribbon weren't there. The solution also lets researchers detach the wireless transceiver and power from the ribbon to lighten the load when experiments are over. Practical use of these tiny LEDs is still a long ways off, but it could lead to both gentler testing as well as better treatment for mental conditions that we don't fully understand today.
