Jul 12, 2022 (Nanowerk News) Producing biomaterials that match the performance of cartilage and tendons has been an elusive goal for scientists, but a new material created at Cornell demonstrates a promising new approach to mimicking natural tissue. The results were published in the Proceedings of the National Academy of...
Operating a smart home by breath control
Jul 12, 2022 (Nanowerk News) Researchers at Case Western Reserve University have created a simple prototype device that enables users to control “smart home” technology by changing their breathing patterns. The self-powered unit fits into the nostrils and has the potential to enhance the quality of life for people with...

The ultimate fate of a star shredded by a black hole
Jul 12, 2022 (Nanowerk News) In 2019, astronomers observed the nearest example to date of a star that was shredded, or “spaghettified,” after approaching too close to a massive black hole. That tidal disruption of a sun-like star by a black hole 1 million times more massive than itself took...

In its first published image, Webb telescope delivers deepest infrared image of universe yet
Jul 12, 2022 (Nanowerk News) NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever...
Flashing creates hard-to-get 2D boron nitride
Jul 12, 2022 (Nanowerk News) Rice University scientists who “flash” materials to synthesize substances like graphene have turned their attention to boron nitride, highly valued for its thermal and chemical stability. The process by the Rice lab of chemist James Tour exposes a precursor to rapid heating and cooling to...

Sub-femtometer-resolution absolute spectroscopy based on dual electro-optic frequency comb
Jul 11, 2022 (Nanowerk News) Optical frequency comb (OFC) provides equidistant comb lines in broad bandwidth, and each comb line corresponds to an absolute optical frequency, which is similar as a comb (or rule) in optical frequency. As the development of femtosecond mode-locked laser and nonlinear optics, in 1999, research...
