| Shapeshifting microrobots can brush and floss teeth Posted: 05 Jul 2022 04:41 PM PDT A robotic microswarm may one day automate the routine of rinsing, brushing, and flossing teeth. A multidisciplinary team developed the technology, which employs a magnetic field to direct the iron oxide nanoparticle-based microrobots into antimicrobial bristle- and floss-shaped arrays. |
| Researchers expand understanding of vortex spread in superfluids Posted: 05 Jul 2022 04:41 PM PDT Researchers have created a model that describes the spread and speed of tornado-like vortex tubes in superfluids. This work expands on a previous study that reported experimental results obtained in superfluid helium-4 within a narrow temperature range. |
| New photocatalytic membrane that can be cleaned using light energy Posted: 05 Jul 2022 01:22 PM PDT Researchers have developed a nanosheet-laminated photocatalytic membrane that demonstrates both excellent water permeance and photocatalytic activity. The membrane's photocatalytic properties make it easier to clean as irradiating the membrane with light successfully reduces fouling. This revolutionary membrane technology can be applied to water purification, and thus has the potential to contribute towards tackling both global environmental and energy issues by helping to ensure a supply of safe drinking water and clean energy. |
| Discovery could inspire new way to detect brain abnormalities Posted: 05 Jul 2022 01:22 PM PDT Scientists have taken a promising step towards a new generation of accurate, affordable and portable devices to detect concussion, epilepsy and dementia. |
| Study points to Armenian origins of ancient crop with aviation biofuel potential Posted: 05 Jul 2022 01:22 PM PDT Camelina, an oilseed plant grown in modern-day Ukraine, may have been a more important and widespread crop than previously thought. New findings could inform breeding programs to improve this crop for biofuels applications. |
| COVID-19 virus spike protein flexibility improved by human cell's own modifications Posted: 05 Jul 2022 01:22 PM PDT Researchers created atomic-level models of the spike protein that plays a key role in COVID-19 infection and immunity, revealing how the protein bends and moves as it seeks to engage receptors. |
| Laser creates a miniature magnetosphere Posted: 30 Jun 2022 05:32 AM PDT A research team realized magnetic reconnection driven by electron dynamics in laser-produced plasmas and measured the pure electron outflows. Their findings will be applied not only to space and astrophysical plasmas, but also to magnetic propulsion and fusion plasmas. |
