Nano-engineering enhances charge transport, promises more efficient future solar cells

(Phys.org) -Solar cells based on semiconducting composite plastics and carbon nanotubes is one of the most promising novel technology for producing inexpensive printed solar cells. Physicists at Umeå University have discovered that one can reduce the number of carbon nanotubes in the device by more than 100 times while maintaining exceptional ability to transport charges. This is achieved thanks to clever nano-engineering of the active layer inside the device. Their results are published as front page news in the journal Nanoscale.

No sedative necessary: Scientists discover new ‘sleep node’ in the brain

(Medical Xpress)-A sleep-promoting circuit located deep in the primitive brainstem has revealed how we fall into deep sleep. Discovered by researchers at Harvard School of Medicine and the University at Buffalo School of Medicine and Biomedical Sciences, this is only the second “sleep node” identified in the mammalian brain whose activity appears to be both necessary and sufficient to produce deep sleep.

The Future Of Robotics Is Soft And Practically Indestructible – Redorbit

Fire, snow, water – and being crushed by a car – are no problem for a new “bio-inspired” robot. The science of soft robotics has taken a major leap forward with the production of the first ever “untethered” soft robot that can get up and walk freely, no longer relying on a cord for power or control.
