A newly developed approach can precisely produce four-stranded β-sheets through metal–peptide coordination, report researchers from Institute of Science Tokyo. Their innovative methodology overcomes long-standing challenges in controlled β-sheet formation, including fibril aggregation and uncontrolled isomeric variation in the final product. This breakthrough could advance the study and application of β-sheets in biotechnology and nanotechnology.
Conventional lithium-ion batteries (LIBs), which use carbon-negative electrodes, are prone to catching fire due to the similar operating potentials of carbon and lithium. Recently, Wadsley–Roth phase oxides, like the TiNb2O7 (TNO), have received considerable attention as potential alternative negative electrode materials that have higher operating potentials than lithium, reducing the risk of fire. In this study, researchers investigated the atomic configuration and network structure of TNO, unveiling key insights for developing safer, high-performance LIBs.
Where did Earth’s water come from? It’s a fundamental scientific question that has never been answered. In fact, NASA reports that we can only observe and understand 5% of the universe — with a whopping 95% remaining a complete mystery because of unobservable dark matter and dark energy. But recent research led by Michigan State University sheds new light on one phenomenon: dark comets.
Darryl Seligman, a postdoctoral fellow in the College of Natural Science’s top-ranked Department of Physics and Astronomy, is the lead author on a paper that uncovers seven new dark comets in our solar system.
With this discovery, he and the research team have doubled the population of known dark comets and are the first to identify two distinct types based on differences observed in orbit and size.
Thanks for a powerful antioxidant, Deinococcus radiodurans can withstand radiation doses 28,000 times greater than what would kill a human. In a new study, scientists discovered how the antioxidant works. Finding could drive the development of designer antioxidants to shield astronauts from cosmic radiation.
Encountering Neptune in 1989, NASA's Voyager mission completed humankind's first close-up exploration of the four giant outer planets of our solar system. Collectively, since their launch in 1977, the twin Voyager 1 and Voyager 2 spacecraft discovered that Jupiter, Saturn, Uranus, and Neptune were far more complex than scientists had imagined. There was a lot more to be learned.
A NASA Hubble Space Telescope observation program called OPAL (Outer Planet Atmospheres Legacy) obtains long-term baseline observations of Jupiter, Saturn, Uranus, and Neptune in order to understand their atmospheric dynamics and evolution.
Eric Stach of the University of Pennsylvania's School of Engineering and Applied Science and colleagues used neural networks to better identify the characteristics of catalysts that drive the creation of liquid fuels from sunlight.
