This week in science, Chinese scientists achieve a significant breakthrough in chip technology, a deep-sea expedition commences in the Western Pacific, NASA grapples with astronaut returns, and the UK’s media regulator faces challenges with online disinformation.
Chinese Breakthrough in Chip Technology
In a groundbreaking development, Chinese scientists have advanced chip technology by creating artificial sapphire dielectric wafers. Their research, published in Nature, addresses the persistent challenge of transistor miniaturization, which often leads to overheating and rapid battery depletion in devices.
The newly developed crystalline sapphire demonstrates ultra-low leakage at the nanometer scale, outperforming traditional materials. This innovation promises more power-efficient devices, a critical advancement for applications in artificial intelligence and the Internet of Things.
Deep-Sea Exploration in the Western Pacific
The Chinese research vessel Shenhai Yihao, also known as Deep Sea No. 1, has embarked on its 2024 Western Pacific International Voyage. Accompanied by China’s manned submersible Jiaolong, the 45-day mission includes 18 planned dives to collect deep-sea organisms, seawater, and sediments, aiming to enhance our understanding of seamount ecosystems.
The expedition is part of the China-led Digital Deep-sea Typical Habitats Program, now supported by 39 countries and regions. As the program’s first international voyage, it involves scientists from Canada, Spain, Colombia, and other participants, fostering international collaboration in marine research.
NASA Considers Extended Stay for Astronauts
NASA is deliberating on keeping astronauts Butch Wilmore and Suni Williams aboard the International Space Station until February due to mid-flight issues encountered by Boeing’s capsule. The agency is evaluating options for their safe return, with the possibility of utilizing a SpaceX capsule under consideration.
Wilmore and Williams arrived at the space station on June 6 during the first crewed test flight of Boeing’s Starliner capsule, initially scheduling a brief stay of about a week. However, problems with Starliner’s thrusters and a helium leak have prolonged their mission as engineers work to resolve the technical challenges.
OFCOM Faces Challenges with Online Disinformation
The UK’s media regulator, OFCOM, is currently grappling with enforcing online safety regulations amid a surge of disinformation. Two weeks ago, a tragic incident occurred when a 17-year-old perpetrated a stabbing at a dance class in Southport, resulting in the deaths of three girls. Misinformation rapidly spread on social media, incorrectly identifying the perpetrator as an asylum seeker.
This false narrative has ignited nationwide anti-immigration protests, escalating into riots. Despite the significant real-world impact, OFCOM is constrained from taking action as the Online Safety Act’s powers are not yet fully operational. Once in effect, the regulator will have the authority to impose fines and even imprisonment for severe violations.
