“There’s something mysterious coming up from the frozen ground in Antarctica, and it could break physics as we know it. Physicists don’t know what it is exactly. But they do know it’s some sort of cosmic ray …
“NASA Curiosity Mission Status Report Engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, this week commanded the agency’s Curiosity rover to switch to its second computer. The switch will enable engineers to do a detailed diagnosis of …
“An international team of scientists led by the University of Groningen’s Zernike Institute for Advanced Materials has identified a way to create quantum bits that emit photons that describe their state at wavelengths close to those used by telecom …
“A KAIST research team led by Professor Keon Jae Lee from the Department of Material Science and Engineering has developed a machine learning-based acoustic sensor for speaker recognition. Acoustic sensors were spotlighted as one of the most intuitive bilateral communication …
“Engineers at the University of California San Diego have developed a super-hydrophobic surface that can be used to generate electrical voltage. When salt water flows over this specially patterned surface, it can produce at least 50 millivolts. The proof-of-concept work …
“The efficiency of a solar cell is one of its most important parameters. It indicates what percentage of the solar energy radiated into the cell is converted into electrical energy. The theoretical limit for silicon solar cells is 29.3 …
“Today, 3-D printing generates parts used in ships, planes, vehicles and spacecraft, but it also requires a lot of babysitting. High-value and intricate parts sometimes require constant monitoring by expert specialists to get them right. Furthermore, if any one section …
“Ultrashort optical pulses are becoming more and more relevant in a number of applications including distance measurement, molecular fingerprinting and ultrafast sampling. Many of these applications rely not only on a single stream of pulses – also known as “optical frequency …
“In simulations, robots move through new environments by exploring, observing, and drawing from learned experiences. When moving through a crowd to reach some end goal, humans can usually navigate the space safely without thinking too much. They can learn from …
“Purdue University researchers have 3D-printed cement paste, a key ingredient of the concrete and mortar used to build various elements of infrastructure, that gets tougher under pressure like the shells of arthropods such as lobsters and beetles. The technique could …
