The first full-depth Chinese deep-sea manned submersible Fendouzhe successfully completed all sea trial tasks and returned to Sanya port on Nov. 28. It successfully landed on the deepest point of the world, Mariana Trench, at 8:12 a.m. on Nov. 10, reaching the depth of 10,909 meters and setting a new record for Chinese manned deep-diving. Three ...
The JUNA (Jinping Underground Nuclear Astrophysics collaboration) 400kV accelerator installed at the China Jinping deep underground Laboratory (CJPL) delivered its first intense beam on December 26. The accelerator is jointly developed by the China Institute of Atomic Energy (CIAE) and the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences. The reactions happening inside of stars play an important ...
With the launch period for NASA’s Mars 2020 Perseverance rover opening in 14 weeks, final preparations for the spacecraft continue at the Kennedy Space Center in Florida. In the past week, the assembly, test, and launch operations team completed important milestones, fueling the descent stage — also known as the sky crane — and attaching ...
Nuclear power continues to expand globally, propelled, in part, by the fact that it produces few greenhouse gas emissions while providing steady power output. But along with that expansion comes an increased need for dealing with the large volumes of water used for cooling these plants. Such wastewater contains nuclear wastewater contaminants made up of ...
A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium. The calculations take scientists a step closer to realizing a gamma-ray laser, which may have applications in medical imaging, spacecraft propulsion, and cancer treatment. Extremely short-lived and only ...
Lightning is one of the most unpredictable phenomena in nature. It regularly kills people and animals and sets fire to homes and forests. It keeps aircraft grounded and damages power lines, wind turbines, and solar panel installations. However, little is known about what triggers lightning, and there is no simple technology for predicting when and ...
Internet censorship by authoritarian governments prohibits free and open access to information for millions of people around the world. Attempts to evade such Internet censorship have turned into a continually escalating race to keep up with ever-changing, increasingly sophisticated strategies. Censoring regimes have had the advantage in that race because researchers must manually search for ...
Researchers at Nanyang Technological University, Singapore (NTU Singapore), have developed a quantum chip that is 1,000 times smaller than current setups, but offers the same superior security the technology is known for. Most leading security standards used in secure communication methods — from withdrawing cash from the ATM to purchasing goods online on the smartphone ...
North Carolina State University researchers have developed what is, to date, the most efficient means of converting sewage sludge and restaurant grease into methane. After treating sewage, wastewater treatment plants are left with solid sludge, called biosolids. For years, utilities have treated biosolids with microbes that produce methane. In recent years, utilities have been adding ...
Researchers have developed a new printer that produces digital 3D holograms with an unprecedented level of detail and realistic color. This new technology could be used to make high-resolution color recreations of objects or scenes for museum displays, architectural models, fine art, or advertisements that do not require glasses or special viewing aids. Research team ...
