The path of breast-to-brain cancer metastasis
Scientists have discovered a signaling pathway that breast tumors exploit to metastasize to the brain.

Brain-computer interfaces without the mess
It sounds like science fiction: controlling electronic devices with brain waves. But researchers have developed a new type of electroencephalogram (EEG) electrode that can do just that, without the sticky gel required for conventional electrodes. Even better, the devices work through a full head of hair. The researchers now report on the flexible electrodes, which could someday be used in brain-computer interfaces to drive cars or move artificial limbs.
Read moreNew microscopes unravel the mysteries of brain organization
The secret of capturing exquisite brain images with a new generation of custom-built microscopes has been revealed. The new microscopes, known as mesoSPIMs, can image the minute detail of brain tissue down to individual neurons that are five times thinner than a human hair, and can uncover the 3D anatomy of entire small organs, faster than ever before.

A study carried out with a new human stem cell-derived model reveals that the most prevalent genetic risk factor of Alzheimer's disease (AD), apolipoprotein E4 (APOE4), impairs the function of human brain immune cells, microglia. These findings pave the way for new, effective treatment approaches for AD.

In experiments in mice, researchers say they have developed a way to successfully transplant certain protective brain cells without the need for lifelong anti-rejection drugs.
