Quantum Leap: Rice Physicists Unlock Flash-Like Memory for Future Qubits

Posted by in categories: computing, quantum physics

Rice University physicists have discovered a phase-changing quantum material — and a method for finding more like it — that could potentially be used to create flash-like memory capable of storing quantum bits of information, or qubits, even when a quantum computer is powered down.

Phase-Changing Materials and Digital Memory

Phase-changing materials have been used in commercially available non-volatile digital memory. In rewritable DVDs, for example, a laser is used to heat minute bits of material that cools to form either crystals or amorphous clumps. Two phases of the material, which have very different optical properties, are used to store the ones and zeros of digital bits of information.

JWST Observes Rare Methane Glow on Brown Dwarf W1935

Posted by in categories: evolution, space

Dr. Jackie Faherty: “Methane emission was not on my radar when we started this project but now that we know it can be there and the explanation for it so enticing I am constantly on the look-out for it. That’s part of how science moves forward.”

Brown dwarfs are too large to be considered planets and too small to produce nuclear fusion like stars. But can they still exhibit some of the same characteristics as planets, like aurorae? This is what a recent study published in Nature hopes to address as a team of international researchers investigated how the brown dwarf W1935, which is located approximately 47 light-years from Earth, could not only possess methane but also have aurorae, all of which are observed on Earth, Jupiter, and Saturn. This study holds the potential to help astronomers better understand the formation and evolution of brown dwarfs, as brown dwarfs remain some of the most mysterious objects in the cosmos despite thousands being identified.

For the study, the researchers used NASA’s James Webb Space Telescope (JWST) and its powerful infrared instruments to observe 12 brown dwarfs, including W1935. In the end, JWST observed strong evidence for the existence of methane with W1935, which the researchers compared to atmospheric models to confirm these findings, along with methane existing on Jupiter, Saturn, and Earth.

NASA Refines National Space Technology Development Priorities

Posted by in category: space travel

As NASA focuses on exploring the Moon, Mars, and the solar system for the benefit of humanity, the agency’s Space Technology Mission Directorate (STMD) is shifting how it prioritizes technology development. As part of this refinement effort, NASA is asking the American aerospace community for feedback on nearly 190 national space technology needs – or shortfalls – it has identified for future space exploration and science endeavors.

“Our ambitious future missions pose many unique challenges, and STMD is positioned – as the nation’s tech base for civil space – to innovate and advance solutions for those problems,” said Dr. Kurt Vogel, associate administrator for Space Technology at NASA Headquarters in Washington. “STMD is developing many critical technologies, but shifting to a more open and collaborative approach allows us to better prioritize our efforts and align with key stakeholder needs while ensuring we all get the most bang out of our investments.”

NASA aims to collect broad aerospace community feedback on critical technology shortfalls – like additive manufacturing, cryogenic fluid management, in-situ resource utilization, and others – ahead of future operations on the Moon and Mars. Understanding and prioritizing the most important and impactful efforts allows STMD to appropriately direct available resources to best support mission needs for NASA and the nation.
