MIT scientists have created the first fully digitally produced plasma sensor to orbit a spacecraft. These plasma sensors, also known as retarding potential analyzers (RPAs), are used by satellites to determine the chemical composition and energy distribution of ions in the atmosphere. The 3D printing and laser cut hardware works and the advanced semiconductor plasma sensors are manufactured in a clean room, which makes them expensive and requires weeks of complex fabrication. In contrast, 3D printed sensors can be produced for tens of dollars in a matter of days. Due to their low cost and fast production, these sensors are ideal for CubeSats. These inexpensive, low-power, and lightweight satellites are often used for communications and environmental monitoring in the Earth’s upper atmosphere. The researchers developed RPA using a glass-ceramic material that is more durable than traditional sensor materials such as silicon and thin-film coatings. By using glass-ceramic in a fab...

A set of genes that promote the sensation of sweetness are also important for protein management during fly development, according to a new study led by the University of Bristol and colleagues, published today (July 21) in the open access journal PLOS Biology. These findings broaden the understanding of key processes in successful development and suggest a link between taste-related genes and impaired protein aggregation. Protein homeostasis or proteostasis, is a set of processes that maintains cellular proteins in a functional state and removes damaged proteins that cannot be repaired. Ribosomes are multi-protein molecular machinery that synthesizes proteins and mutations in genes encoding ribosomal proteins not only impair protein synthesis but also impair proteostasis, leading to chronic proteotoxic stress. That stress, in turn, has a number of cellular consequences and results in delayed development and other irregularities. To better understand the disturbances caused by such ...

By David L. Chandler, Massachusetts Institute of Technology 10 July 2022 Scientists at MIT have developed a method to enable such quantum sensors to detect arbitrary frequencies, without losing their ability to measure nanometer-scale features. MIT MIT stands for Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; manipulation; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances. Their stated goal is to make the world a better place through education, research, and innovation. ” data-gt-translate-attributes=”[{” attribute=””>MIT engineers expand the capabilities of these ultrasensitive nanoscale detectors, with potential uses for biological sensing and quantum computing Performing computation using quantu...
