How the brain ‘takes out the trash’ while we sleep

Image shows cerebral spinal fluid (in blue) entering the brain via a “plumbing system” that piggybacks on the brain’s blood vessels (credit: URMC) A new study shows that a recently discovered system that flushes waste from the brain is primarily active during sleep, giving fresh meaning to the old adage that a good night’s sleep clears the […]

Restoring touch for amputees using a touch-sensitive prosthetic hand

New research at the University of Chicago is laying the groundwork for touch-sensitive prosthetic limbs that one day could convey real-time sensory information to amputees via a direct interface with the brain (credit: PNAS) New research at the University of Chicago is laying the groundwork for touch-sensitive prosthetic limbs that one day could convey real-time sensory information to amputees via […]

Building 3D heart tissue with a programmable chip-making device

This image of shows multiple thin layers of an elastic “biorubber” polymer (purple) and interwoven muscle tissue (green) formed from neonatal rat heart cells (credit: MIT photo) By adapting a programmable device used to manufacture integrated circuits, MIT Draper Laboratory researchers have devised a semi-automated process to build three-dimensional heart tissue, MIT Technology Reviewreports. Tissue is […]

Scientists sequence genome of ‘sacred lotus,’ may hold anti-aging secrets

Nelumbo nucifera from China, more commonly known as the “sacred lotus” (credit: Jane Shen-Miller/UCLA) A team of 70 scientists from the U.S., China, Australia and Japan reports having sequenced and annotated more than 86 percent of the genome of the “sacred lotus,” which is believed to have a powerful genetic system that repairs genetic defects, and may […]

How to convert an iPhone into a handheld biosensor

University of Illinois researchers developed a cradle and app for the iPhone to make a handheld biosensor that uses the phone’s own camera and processing power to detect any kind of biological molecules or cells (credit: Brian T. Cunningham/University of Illinois) University of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone (Android version […]

Electrical brain stimulation helps people learn math faster

Testing the effects of transcranial random noise stimulation the prefrontal cortex. The orange plates are near-infrared spectroscopy devices, using infrared light to measure blood-flow changes. (Credit: Albert Snowball et al./Current Biology) A harmless form of brain stimulation called transcranial random noise stimulation (TRNS) can help you learn math faster, researchers report. “With just five days of cognitive training and […]
