| Scientists observe mysterious death of a star emitting six rings Posted: 28 Mar 2022 12:39 PM PDT Astrophysicists studying in unprecedented detail a red giant star named V Hydrae have witnessed the star's mysterious death throes. Researchers discovered that the carbon-rich star has expelled six slowly expanding molecular rings and two hourglass-shaped structures ejecting matter out into space at high speeds. |
| Quantum information theory: Quantum complexity grows linearly for an exponentially long time Posted: 28 Mar 2022 12:06 PM PDT Physicists know about the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and to describe the behavior of complex quantum many-body systems -- for example, black holes and wormholes in the universe. Now, researchers have proven a mathematical conjecture about the behavior of complexity in such systems, increasing the viability of this bridge. |
| Squid skin-inspired cup cozy will keep your hands cool and your coffee hot Posted: 28 Mar 2022 10:37 AM PDT Drawing inspiration from cephalopod skin, engineers have invented an adaptive fabric that can be used to insulate the contents of coffee cups, to-go boxes and containers of almost any size. In a new paper, the researchers describe the manufacturing process they developed which enables economical mass production of their novel material. |
| Unprecedented videos show RNA switching ‘on’ and ‘off’ Posted: 28 Mar 2022 10:36 AM PDT Using new simulations, researchers discovered one part of RNA smoothly invades and displaces another part of the same RNA, enabling the structure to rapidly and dramatically change shape. Called strand displacement, this mechanism appears to switch genetic expression from 'on' to 'off'. |
| Ancient helium leaking from core offers clues to Earth's formation Posted: 28 Mar 2022 10:36 AM PDT Helium-3, a rare isotope of helium gas, is leaking out of Earth's core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside a solar nebula, which has long been debated. |
| New technology could make biopsies a thing of the past Posted: 28 Mar 2022 08:21 AM PDT Researchers have developed a technology that could replace conventional biopsies and histology with real-time imaging within the living body. MediSCAPE is a high-speed 3D microscope capable of capturing images of tissue structures that could guide surgeons to navigate tumors and their boundaries without needing to remove tissues and wait for pathology results. |
| Chaos theory provides hints for controlling the weather Posted: 28 Mar 2022 07:13 AM PDT Researchers have used computer simulations to show that weather phenomena such as sudden downpours could potentially be modified by making small adjustments to certain variables in the weather system. They did this by taking advantage of a system known as a 'butterfly attractor' in chaos theory, where a system can have one of two states -- like the wings of a butterfly -- and that it switches back and forth between the two states depending on small changes in certain conditions. |
| Mysterious death of carbon star plays out like six-ring circus Posted: 28 Mar 2022 06:20 AM PDT Scientists studying V Hydrae (V Hya) have witnessed the star's mysterious death throes in unprecedented detail. The team discovered six slowly-expanding rings and two hourglass-shaped structures caused by the high-speed ejection of matter out into space. |
| Posted: 25 Mar 2022 06:38 AM PDT Researchers used mathematical methods to compensate for changes in the natural illumination during the course of long-exposure scan of stained-glass windows. This approach may help digitize other cultural artifacts more accurately. |
