Neuroscientists at the Francis Crick Institute have developed a new technique to map electrical microcircuits* in the brain at far more detail than existing techniques*, which are limited to tiny sections of the brain (or remain confined to simpler model organisms, like zebrafish). In the brain, groups of neurons that connect up in microcircuits help [...]



How to grow functioning human muscles from stem cells

Wed, 10 Jan 2018 07:54:45 +0000

Biomedical engineers at Duke University have grown the first functioning human skeletal muscle from human induced pluripotent stem cells (iPSCs). (Pluripotent stem cells are important in regenerative medicine because they can generate any type of cell in the body and can propagate indefinitely; the induced version can be generated from adult cells instead of embryos.) [...]

Brainwave ‘mirroring’ neurotechnology improves post-traumatic stress symptoms

Thu, 04 Jan 2018 04:08:52 +0000

You are relaxing comfortably, eyes closed, with non-invasive sensors attached to your scalp that are picking up signals from various areas of your brain. The signals are converted by a computer to audio tones that you can hear on earbuds. Over several sessions, the different frequencies (pitches) of the tones associated with the two hemispheres [...]

Why (most) future robots won’t look like robots

Tue, 05 Dec 2017 04:10:21 +0000

Future robots won’t be limited to humanoid form (like Boston Robotics’ formidable backflipping Atlas). They’ll be invisibly embedded everywhere in common objects. Such as a shoe that can intelligently support your gait, change stiffness as you’re running or walking, and adapt to different surfaces — or even help you do backflips. That’s the vision of researchers [...]



Using light instead of electrons promises faster, smaller, more-efficient computers and smartphones

Sat, 02 Dec 2017 02:08:28 +0000

By forcing light to go through a smaller gap than ever before, a research team at Imperial College London has taken a step toward computers based on light instead of electrons. Light would be preferable for computing because it can carry much-higher-density information, it’s much faster, and more efficient (generates little to no heat). But [...]
