| Construction workers at risk of unintentionally exposing families to multiple toxic metals Posted: 18 Feb 2022 12:30 PM PST A new study provides evidence that construction workers, in particular, are at high risk of inadvertently tracking a host of other toxic metals into their homes. The study identifies and measures the highest number of metals --30-- in construction workers' homes, to date. |
| Researchers link cutting-edge gravity research to safer operation of construction cranes Posted: 18 Feb 2022 08:07 AM PST The research provides new insight into the maneuvers required to safely and quickly transport heavy loads. |
| Forget handheld virtual reality controllers: a smile, frown or clench will suffice Posted: 18 Feb 2022 07:07 AM PST An international team of researchers has taken facial recognition technology to the next level, using a person's expression to manipulate objects in a virtual reality setting without the use of a handheld controller or touchpad. |
| Nebulin no longer nebulous! Scientists obtain first high-resolution 3D image of muscle protein Posted: 18 Feb 2022 07:07 AM PST Scientists have obtained the first high-resolution 3D image of nebulin, a giant actin-binding protein that is an essential component of skeletal muscle. This discovery has brought to light the chance to better understand the role of nebulin, as its functions have remained largely nebulous due to its large size and the difficulty in extracting nebulin in a native state from muscle. The team used electron cryo-tomography to decipher the structure of nebulin in impressive detail. Their findings could lead to novel therapeutic approaches to treat muscular diseases, as genetic mutations in nebulin are accompanied by a dramatic loss in muscle force known as nemaline myopathy. |
| Easy aluminum nanoparticles for rapid, efficient hydrogen generation from water Posted: 18 Feb 2022 07:06 AM PST For years, researchers have tried to find efficient and cost-effective ways to harness the extreme reactivity of aluminum to generate clean hydrogen fuel. A new study shows that an easily produced composite of gallium and aluminum creates aluminum nanoparticles that react rapidly with water at room temperature to yield large amounts of hydrogen. |
| CROPSR: A new tool to accelerate genetic discoveries Posted: 17 Feb 2022 11:13 AM PST Scientists have developed CROPSR, the first open-source software tool for genome-wide design and evaluation of guide RNA (gRNA) sequences for CRISPR/Cas9 experiments. This tool significantly shortens the time required to design a CRISPR experiment and reduces the challenge of working with complex crop genomes. It should accelerate bioenergy crop development as well as broader crop improvements and other gene-editing research. |
| Reducing negative impacts of Amazon hydropower expansion on people and nature Posted: 17 Feb 2022 11:13 AM PST Rapid hydroelectric dam expansion in the Amazon poses a serious threat to Earth's largest and most biodiverse river basin. There are 158 dams in the Amazon River basin, with another 351 proposed; these projects are typically assessed individually, with little coordinated planning. A new study provides a computational approach for evaluating basin-level tradeoffs between hydropower and ecosystem services, with the goal of guiding sustainable dam siting. |
| Vortex microscope sees more than ever before Posted: 17 Feb 2022 11:13 AM PST A new imaging technology uses polarized 'optical vortices' to provide a detailed, dynamic view of molecules in motion. |

| Size matters in particle treatments of traumatic injuries Posted: 17 Feb 2022 09:23 AM PST Chemical engineers tested how different-sized polymer nanoparticles circulate in the body and interact with platelets, the cells that promote blood clotting. Such particles could be used to help stop internal bleeding after traumatic injuries. |
| New DNA computer assesses water quality Posted: 17 Feb 2022 09:23 AM PST Synthetic biologists have developed a low-cost, easy-to-use, hand-held device that can let users know -- within mere minutes -- if their water is safe to drink. The new device works by using powerful and programmable genetic networks, which mimic electronic circuits, to perform a range of logic functions. |
| Monte Carlo simulations bring new focus to electron microscopy Posted: 17 Feb 2022 09:23 AM PST A new method is using Monte Carlo simulations to extend the capabilities of transmission electron microscopy and answer fundamental questions in polymer science. |
| Researchers combine piezoelectric thin film and metasurfaces to create lens with tunable focus Posted: 17 Feb 2022 09:23 AM PST Tunability in lenses typically requires bulky components, but researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied. The compact and lightweight lens could be useful for portable medical diagnostic instruments, drone-based 3D mapping and other applications where miniaturization can open new possibilities. |
