BEIJING, June 28 (Xinhua) -- The following are the highlights of China's major technology news from the past week:
WORLD INTELLIGENCE CONGRESS
Without real exhibition halls, the fourth World Intelligence Congress, a major artificial intelligence event held in north China's Tianjin Municipality, rode the technology wave to draw 392 million online views in its annual session.
To prevent the spread of COVID-19, organizers adopted China's advanced cloud-based virtual solutions for online viewers to take part in or watch a series of business activities and competitions, such as the world intelligence driving challenge, which drew 145 teams from countries including the United States, Japan and Germany.
NEXT-GENERATION BATTERY LAB
Contemporary Amperex Technology Co. Limited, China's largest lithium-ion battery maker, broke ground on a new laboratory to develop next-generation batteries. It is being constructed at its headquarters in the city of Ningde, east China's Fujian Province.
The "21C Lab," covering an area of 18 hectares, will focus on the development of next-generation electrochemical energy storage systems, and new energy conversion systems.
RAILWAY SOUND-ABSORBING TUNNEL
An 847-meter-long, sound-absorbing tunnel on the high-speed railway linking Beijing and the Xiong'an New Area in north China's Hebei Province, has been completed. This will help avoid the noise emanating from trains and tracks, engineers with China Railway Group Limited said.
With increasing additions of transportation hubs and railway lines across the country, train noise mitigation is of concern to people, and the newly-built tunnel seems one of the best solutions. According to its developers, the tunnel is equivalent to a sound barrier, and can minimize the noise generated by bullet trains traveling at a speed of 350 kph.
3D BIOPRINTING
A team of international researchers have developed a noninvasive 3D bioprinting system that can print an ear inside the body of a mouse.
In the new study, researchers from Sichuan University in China, Ghent University in Belgium and the University of California San Diego in the U.S. used near-infrared light to polymerize bio-ink inside the body without invasive incisions
The researchers said that the latest noninvasive 3D bioprinting system holds the potential to be used in organ reconstruction or tissue repair, such as microtia in which the cartilage of the outer ear is underdeveloped or absent. Enditem
