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

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(…)
