| Microscopic view on asteroid collisions could help us understand planet formation Posted: 24 Feb 2022 06:11 AM PST A new way of dating collisions between asteroids and planetary bodies throughout our solar system's history could help scientists reconstruct how and when planets were born. |
| Navigation tools could be pointing drivers to the shortest route — but not the safest Posted: 23 Feb 2022 01:45 PM PST Time for a road trip. You punch the destination into your GPS and choose the suggested route. But is this shortest route the safest? Not necessarily, according to new findings. |
| Water filtration membranes morph like cells Posted: 23 Feb 2022 11:32 AM PST Morphogenesis is nature's way of building diverse structures and functions out of a fixed set of components. While nature is rich with examples of morphogenesis -- cell differentiation, embryonic development and cytoskeleton formation, for example -- research into the phenomenon in synthetic materials is scant. Researchers are taking a step forward using electron tomography, fluid dynamics theories and machine learning to watch soft polymers as the polymers learn from nature. |
| Cosmic flashes pinpointed to a surprising location in space Posted: 23 Feb 2022 10:35 AM PST Astronomers have been surprised by the closest source of mysterious flashes in the sky called fast radio bursts. Precision measurements with radio telescopes reveal that the bursts are made among old stars, and in a way that no one was expecting. The source of the flashes, in nearby spiral galaxy M 81, is the closest of its kind to Earth. |
| Colossal black holes locked in dance at heart of galaxy Posted: 23 Feb 2022 10:35 AM PST A sinusoidal light curve spanning 45 years points to the presence of orbiting supermassive black holes at the core of a distant galaxy. |
| New artificial intelligence tool detects often overlooked heart diseases Posted: 23 Feb 2022 10:35 AM PST Physician-scientists have created an artificial intelligence (AI) tool that can effectively identify and distinguish between two life-threatening heart conditions that are often easy to miss: hypertrophic cardiomyopathy and cardiac amyloidosis. |
| Pioneering simulations focus on HIV-1 virus Posted: 23 Feb 2022 10:34 AM PST First-ever biologically authentic computer model was completed of the HIV-1 virus liposome. Key finding from the simulations is the formation of sphingomyelin and cholesterol rich microdomains. HIV-1 is known to preferentially bud from regions of the host cell membrane where these constituents are in high abundance. Scientists are hopeful this basic research into viral envelopes can help efforts to develop new HIV-1 therapeutics, as well as laying a foundation for study of other enveloped viruses such as the novel coronavirus. |
| Posted: 23 Feb 2022 10:34 AM PST Thirty-six million people in the U.S. use an energy system developed by a handful of activists in the 1990s. A scholar examines this unusual story. |
| Risks of using AI to grow our food are substantial and must not be ignored, warn researchers Posted: 23 Feb 2022 08:12 AM PST Artificial intelligence (AI) is on the cusp of driving an agricultural revolution, and helping confront the challenge of feeding our growing global population in a sustainable way. But researchers warn that using new AI technologies at scale holds huge risks that are not being considered. |
| Basis for next-gen bioprocesses Posted: 23 Feb 2022 07:49 AM PST Succinic acid is an important precursor for pharmaceutical and cosmetic products and also serves as a component in biodegradable plastics. It is currently derived mainly from petroleum-based processes. Researchers are using the marine bacterium Vibrio natriegens as a biocatalyst. This could permit the production of succinic acid in sustainable processes using renewable raw materials. |
| Astronomers map mysterious element in space Posted: 23 Feb 2022 07:49 AM PST A research team has provided an important clue to the origin of the element Ytterbium in the Milky Way, by showing that the element largely originates from supernova explosions. The groundbreaking research also provides new opportunities for studying the evolution of our galaxy. |
| Posted: 21 Feb 2022 05:57 AM PST Imagine making some liquids mix that do not mix, then unmixing them. In one of the grand challenges of science, a device which previously 'unboiled' egg protein is now unraveling the mystery of incompatible fluids -- a development that could enhance many future products, industrial processes and even the food we eat. |
