Researchers Grow Brain Cells on a Chip

Nanowire scaffold could act as a brain prosthetic where neurons grow and form connections Photo: Stuart Hay/ANU Every human thought starts with a signal traveling from one neuron to another in the brain. Yet we know relatively little about how these connections form. In an effort to watch that process unfold, Australian researchers engineered a nanowire scaffold(…)

Smartphone-Controlled Cells Keep Diabetes In Check

Smartphone-Controlled Cells Keep Diabetes In Check

Engineered cells implanted in diabetic mice produce insulin on-demand Photo: Shanghai Key Laboratory of Regulatory Biology Smartphones can already control homes and cars, and diagnose diseases. Chinese and Swiss researchers now show that a smartphone can command engineered cells implanted in diabetic mice to produce insulin. The researchers demonstrated a clever closed-loop system in which a digital(…)

Efficiency of Silicon Solar Cells Climbs

Efficiency of Silicon Solar Cells Climbs

Japanese materials company prototypes a 26.3% efficient silicon cell, steps away from the 29% theoretical maximum Photo: Kunta Yoshikawa/Kaneka/Nature Energy In research published this week in Nature Energy , researchers at Kaneka Corporation, a resin and plastics manufacturer based in Osaka, describe the first silicon solar cell to achieve a record-breaking 26.3-percent efficiency—a 0.7-percent increase over the previous(…)

Nanoelectrode Array Sees Signals From Inside a Network of Cells

Nanoelectrode Array Sees Signals From Inside a Network of Cells

CMOS-based array could test drugs better by recording from within each cell to map an entire network Image: Harvard University/Nature Nanotechnology Researchers at Harvard University have developed a nanoelectrode array capable of imaging the electrical signals within the living cells. While other technologies have been able to measure these signals, this new complimentary metal oxide semiconductor(…)
