Growing a cerebral tract in a microscale brain model  

An international research team modeled the growth of cerebral tracts. Using neurons derived from stem cells, they grew cortical-like spheroids. In a microdevice, the spheroids extended bundles of axons toward each other, forming a physical and electrical connection. Fascicles grew less efficiently when one spheroid was absent, and when a gene relevant to cerebral tract formation was knocked-down. The study further illuminates brain growth and developmental disorders.

Researchers Resuscitate Pig Brains Hours After Death  

Researchers say they've rebooted pigs' brains four hours after the animals died. The scientists managed to restore some blood flow and brain cell activity to the dead animals' brains by pumping a protective solution through the tissue using a proprietary technology they call BrainEx. The brain was never alert and researchers did not restore consciousness, but the work could lead to new ways to aid recovery after trauma like heart attacks and strokes, the researchers say. "BrainEx...

Astronomers Find Oldest Type of Molecule in Space  

Everything has a beginning. That's true for stories, for people, for the universe and even for chemistry. The Big Bang itself produced just a handful of elements (variations of hydrogen, helium and lithium nuclei), so researchers have a pretty good sense of what the first atoms and molecules might have been. But the very first molecular bond to form, linking together atoms of different elements in a single molecule, has long been missing in action. Known as a helium hydride ion (HeH+), ...

General anesthesia hijacks sleep circuitry to knock you out  

Researchers have found that general anesthesia induces unconsciousness by hijacking the neural circuitry that makes us fall sleep. They traced this neural circuitry back to a cluster of cells at the base of the brain responsible for churning out hormones to regulate bodily functions, mood, and sleep. The finding could lead to better drugs capable of putting people to sleep with fewer side effects.
