Improving fitness may counteract brain atrophy in older adults Older adults that improved their fitness through a moderate intensity exercise program increased the thickness of their brain's cortex, the outer layer of the brain that typically atrophies with Alzheimer's disease. These effects were found in both healthy older adults and those diagnosed with mild cognitive impairment, an early stage of Alzheimer's disease.
Can stem cell technology be harnessed to generate biological pacemakers? Although today's pacemakers are lifesaving electronic devices, they are limited by their artificial nature. For example, the devices require regular maintenance, must be replaced periodically, and can only approximate the natural regulation of a heartbeat. A new article highlights the promise and limitations of new methods based on stem cell and reprogramming technologies to generate biological pacemakers that might one day replace electronic pacemakers.
How does our brain form creative and original ideas? A new study attempted to crack the connection between brain activity and creativity. The results shed a new, perhaps unexpected light, on our ability to think outside the box
Newly discovered signaling molecule helps neurons find their way in developing brain In the developing nervous system, some neurons must extend their branches to connect one half of the brain with the other. A new study sheds light on the molecular mechanisms that guide the winding paths of their axons
