Tianjin University team develops “brain whisperer”, a brain-computer interface for writing
A cap picks up electroencephalograph (EEC) signals and sends them to a computer. Brain patterns, which carry the user’s intent, are decoded by an algorithm on the device. Eventually, the information is converted into instructions and triggers an action. Using this interface, WEI Siwen, a graduate student at Tianjin University, typed 69 characters in one minute via mind control, winning the first prize in a BCI competition held earlier this year. The speed proved faster than hand typing.
The device is applicable in medicine, rehabilitation, brain cognition, neural feedback and signal processing, researchers said, adding that the BCI technology will be adapted for civilian use, and the device will become easier to carry and use, becoming wearable in the future.

Chinese consortium develops nuclear emergency response robots
Four 100 kg nuclear emergency response robots, designed by China General Nuclear Power Corporation (CGN) and the CAS Institute of Optics and Electronics serve at Daya Bay Nuclear Power Plant in Guangdong province since last November. They carry out both land and...
CAS Institute of Chemistry develops bio-optical hybrid system for enhanced photosynthesis
The system developed by WANG Shu and colleagues is based on fluorene-based light-harvesting polymers linked to photosystem II. The polymer coat on the surface of chloroplasts strongly absorbs incident UV light and emits visible light which chloroplasts can absorb....
Qingdao green tides may be a result of Porphyra production in Northern Jiangsu
Green tides in the Yellow Sea have besieged the city of Qingdao every summer over the past decade. The blooms are usually formed by Ulva prolifera algae. A recent study confirmed that the increase in green algae was caused by seaweed farming in neighboring Jiangsu...
