Chinese researchers have achieved a new world record after scientists developing an “artificial sun” ran the device on Friday at a record-shattering temperature of 120 million degrees Celsius for over 100 seconds.
The experiment was held at the Institute of Plasma Physics of the Chinese Academy of Sciences (ASIPP) in Hefei, China.
The exercise is a part of the China’s efforts to develop new clean energy sources through the development of next-generation nuclear fusion reactor technology.
Known as the Experimental Advanced Superconducting Tokamak (EAST), the “Chinese artificial sun” managed to generate plasma temperatures of 120 million degrees Celsius for 101 seconds before scientists also realized a temperature of 160 million degrees Celsius for an additional 20 seconds.
The goal of EAST is to create Sun-like energy using deuterium, a hydrogen isotope that is plentiful in the ocean and can provide a steady flow of clean energy. According to estimates, one liter of seawater contains enough deuterium to produce energy equivalent to 300 liters of gasoline.
China hopes that it can replace fossil fuels such as coal, oil and natural gas with the fusion energy in order to achieve carbon neutrality and a more ecological society.
“It’s a huge achievement in China’s physics and engineering fields. The experiment’s success lays the foundation for China to build its own nuclear fusion energy station,” ASIPP director Song Yuntao said, according to People’s Daily.
The EAST artificial sun is also part of the International Thermonuclear Experimental Reactor, a joint effort by global scientists that includes the input of scientists from China, the European Union, India, Japan, South Korea, Russia and the United States.
Experts hope that if development proceeds at the current rate, successful nuclear fusion could be achieved within three decades.
Awesome New Infrared Goggles Could Help Blind People ‘See’ Surroundings
People who are blind or deal with low vision face a unique number of challenges in their daily lives, ranging from accessing published material to holding a job or living on one’s own.
However, emerging infrared technology under research could help the blind and visually impaired navigate the world around them using a pair of innovative goggles.
In new research recently published and yet to be peer-reviewed, Manuel Zahn and Armaghan Ahmad Khan at Germany’s Technical University of Munich explored how their 3D camera and haptic feedback armband can assist people with low vision.
“Even in the present era, visually impaired people face a constant challenge of navigation,” the pair wrote. “The most common tool available to them is the cane. Although the cane allows good detection of objects in the user’s immediate vicinity, it lacks the ability to detect obstacles further away.”
The two students’ design deploys two infrared cameras placed in a 3D-printed goggles prototype to get a stereoscopic view that is transformed by a small computer into a map of the user’s surroundings. The infrared gear also works in the dark. The armband then uses 25 actuators arranged in a grid that vibrates when users come close to objects while also assisting them in their orientation. As users walk near obstacles, the vibration intensity of the actuators increases.
In tests, subjects enjoyed roughly 98 percent accuracy while getting through obstacle pathways, with all five participants completing the course in their first run. After two additional runs, the volunteers were able to navigate the obstacles more rapidly.
Zahn and Khan frequently cited Microsoft’s Kinect motion detection system for the Xbox in their study, but the pair are confident that their own setup will be far smaller, cheaper and less conspicuous than the gaming device.
The new headset could offer an interesting opportunity for blind and partially sighted people to clear the myriad obstacles they face when performing regular tasks or navigating the world around them.
In World First, Man Receives Heart Transplanted From Gene-Hacked Pig
In a groundbreaking world first, a 57-year-old man in the U.S. has become the first person in the world to receive a heart transplant from a genetically-modified pig.
The revolutionary procedure’s apparent success offers hope to hundreds of thousands of people who are struggling with failing vital organs amid scarce supplies of human organs.
The patient, David Bennett of Maryland, is in good shape days after the experimental seven-hour operation took place in Baltimore on Friday, according to the University of Maryland Medical Center.
The surgical procedure is the result of years of fervent efforts by researchers to develop pigs whose organs would be compatible with the human body, and was made possible by recent advances in gene editing and cloning technology. The heart transplant was preceded months ago by a successful kidney transplant in New York which also used an organ harvested from a genetically engineered pig.
“This is a watershed event,” said David Klassen, chief medical officer at the United Network for Organ Sharing, reports New York Times. “Doors are starting to open that will lead, I believe, to major changes in how we treat organ failure.”
The University of Maryland doctors received a special dispensation from regulators to carry out the procedure due to the fact that Bennett’s death was certain in the absence of a transplant.
Surgeon Bartley Griffith, who took part in the transplant, expressed pride in taking part in bringing the world “one step closer to solving the organ shortage crisis,” reports BBC. Roughly 17 people die every day in the U.S. while awaiting transplants, which are in extremely short supply.
“People die all the time on the waiting list, waiting for organs. If we could use genetically engineered pig organs they’d never have to wait, they could basically get an organ as they needed it,” said Christine Lau, Department of Surgery at the University of Maryland School of Medicine.
“Plus, we wouldn’t have to fly all over the country at night-time to recover organs to put them into recipients.”
