Northwestern University researchers have developed a new RNA switch that activates genes thousands of times better than nature and has applications in diagnostics and metabolic engineering.
Many of today's technologies, such as, solid-state lighting, transistors in computer chips, and batteries in cell phones rely simply on the charge of the electron and how it moves through the material. In certain materials, such as the monolayer transition metal dichalcogenides (TMDs), electrons can be selectively placed into a chosen electronic valley using optical excitation.
Brown University researchers have improved the resolution of terahertz emission spectroscopy -- a technique used to study a wide variety of materials -- by 1,000-fold, making the technique useful at the nanoscale.
What appears to be a unique selfie opportunity was actually a critical photo for the cryogenic testing of NASA's James Webb Space Telescope in Chamber A at NASA's Johnson Space Center in Houston. The photo was used to verify the line of sight (or path light will travel) for the testing configuration.
This study examines how small-world networks occur within bigger and more complex structures.
It's really surprising: it turns out that among simple electronic circuits, built of just a few components, many of them behave chaotically, in an extremely complicated, practically unpredictable manner. Physicists from the Institute of Nuclear Physics Polish Academy of Sciences in Cracow have discovered, examined and described dozens of new, unusual circuits of this type. What is especially interesting is that one of the circuits generates voltage pulses very similar to those produced by neurons, only it does so a thousand times faster.
America's white working-class communities feel they are being kept in the 'slow lane' of social mobility while other groups speed past, according to a year-long study by UK and US researchers into their social and political views. Communities in five cities were interviewed and their thoughts captured during a period spanning part of the 2016 presidential race, which heralded the most dramatic shift in political dynamics in recent US history.
Daily, people spend over three hours on their phones. While ever-smarter digital devices have made many aspects of our lives more efficient, a growing body of evidence suggests that, by continuously distracting us, they are harming our ability to concentrate. Studies across the world show that students constantly use their phones when they are in class. A strong body of evidence suggests that media use during lectures is associated with lower academic performance.
A Berkeley Lab-led research team has discovered a surprising set of chemical reactions involving magnesium that degrade battery performance even before the battery can be charged up. The findings could steer the design of next-gen batteries.
'The autonomous HydroCamel II integrates state-of-the-art technologies, including high-level maneuvering in six degrees of freedom and an ability to dive almost vertically,' says Professor Hugo Guterman of the BGU Department of Electrical and Computer Engineering and head of LAR. 'Until now, these capabilities were limited to remotely operated underwater vehicles (ROVs), which must be tethered by an umbilical cable to a host ship for its power and air source. The HydroCamel II is completely autonomous.'
