Using an electron microscope, researchers have peered down inside the brain of an adult mouse at a scale previously unachievable, generating dramatic color images at 3-nm-pixel resolution. The research was published Thursday July 30 in an open-access paper in the journal Cell. Focusing on a small area of the mouse brain that receives sensory information from

Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, Georgia Tech researchers have developed a new supercapacitor material that provides electrical-energy storage capacity rivaling some batteries. Capacitors can provide large amounts of current quickly (high power density), unlike batteries. So if this material can be scaled up from laboratory samples,

In a study conducted at UCLA, five men who had been completely paralyzed were able to move their legs in a rhythmic motion thanks to a new, noninvasive neuromodulation and pharmacological procedure that stimulates the spinal cord. The researchers believe this to be the first time voluntary leg movements have ever been relearned in completely

Like a jazz combo, the human brain improvises while its rhythm section keeps up a steady beat. But when it comes to taking on intellectually challenging tasks, groups of neurons tune in to one another for a fraction of a second and harmonize, then go back to improvising, according to new research led by UC Berkeley.

Virginia Tech scientist Warren Ruder, an assistant professor of biological systems engineering, has created an in silico (computer-simulated) model of a biomimetic robot controlled by a bacterial brain. The study was inspired by real-world experiments where the mating behavior of fruit flies was manipulated using bacteria, and in which mice exhibited signs of lower stress when implanted
