MIT physicists and colleagues have created a five-lane superhighway for electrons that could allow ultra-efficient electronics and more. The work, reported in the May 9 issue of Science, is one of several important discoveries by the same team over the last year involving a material that is essentially a unique form of pencil lead.
A team of scientists at the Department of Energy’s SLAC National Accelerator Laboratory are developing new methods to probe the universe’s minute details at extraordinary speeds.
Knowledge about the early forms of life in the universe that may have led to the development of life on Earth remains largely unknown. However, a group of scientists at the University of Hawaiʻi at Mānoa are attempting to change that.
A portable sweeping frequency reader was kept nearby to record and analyze the signals from the RF tags (it serves as the machine part of HMI).
The researchers demonstrated that their smart contact lenses can detect gazing directions and real-time gazing points, which could be used for robot control and software interaction.
Further, they showed that the lenses are very stable and can be worn for up to 12 hours in different environmental conditions. They have also shown that the lenses can detect eye closure.
We generally assume that when humans are walking or otherwise moving in space, their head faces towards the direction they are traveling in. Nonetheless, travel direction and head direction are distinct factors associated with the processing of different types of spatial information.
Researchers at the University of Rochester have used surface acoustic waves to overcome a significant obstacle in the quest to realize a quantum internet.
Scientists at the Paul Scherrer Institute (PSI) have for the first time precisely characterized the enzyme styrene oxide isomerase, which can be used to produce valuable chemicals and drug precursors in an environmentally friendly manner. The study appears today in the journal Nature Chemistry.
Enzymes are powerful biomolecules that can be used to produce many substances at ambient conditions. They enable “green” chemistry, which reduces environmental pollution resulting from processes used in synthetic chemistry. One such tool from nature has now been characterized in detail by PSI researchers: the enzyme styrene oxide isomerase. It is the biological version of the Meinwald reaction, an important chemical reaction in organic chemistry.
“The enzyme, discovered decades ago, is made by bacteria,” says Richard Kammerer of PSI’s Biomolecular Research Laboratory. His colleague Xiaodan Li adds: “But because the way it functions was not known, its practical application has been limited up to now.” The two researchers and their team have elucidated the structure of the enzyme as well as the way it works.
A collaborative effort between Harvard and Google has led to a breakthrough in brain science, producing an extensive 3D map of a tiny segment of human brain, revealing complex neural interactions and laying the groundwork for mapping an entire mouse brain.
A cubic millimeter of brain tissue may not sound like much. But considering that tiny square contains 57,000 cells, 230 millimeters of blood vessels, and 150 million synapses, all amounting to 1,400 terabytes of data, Harvard and Google researchers have just accomplished something enormous.
A Harvard team led by Jeff Lichtman, the Jeremy R. Knowles Professor of Molecular and Cellular Biology and newly appointed dean of science, has co-created with Google researchers the largest synaptic-resolution, 3D reconstruction of a piece of human brain to date, showing in vivid detail each cell and its web of neural connections in a piece of human temporal cortex about half the size of a rice grain.
NASA ’s upcoming Gateway space station, set to orbit the Moon, will rely heavily on its Power and Propulsion Element (PPE) for energy and maintaining its orbit. Currently under development with Maxar Technologies, the PPE uses solar electric propulsion to efficiently power the station. This system, designed to significantly reduce the need for propellant, will be integrated with Gateway’s habitation module and launched to support deep space exploration and future Artemis missions to Mars.
As astronauts live and work on Gateway to enable sustained exploration and research in deep space, their efforts will be made possible by Gateway’s Power and Propulsion Element (PPE). A foundational component of the lunar outpost and the most powerful solar electric spacecraft ever flown, PPE will provide Gateway with power and allow it to maintain its unique orbit around the Moon.
