| Decoy particles trick coronavirus as it evolves Posted: 11 Apr 2022 03:43 PM PDT Decoy nanoparticles mimic cells, attracting viruses to bind to them rather than infecting healthy cells. Researchers tested the strategy against the novel coronavirus and five of its variants, finding it was consistently effective. |
| New transistor could cut 5% from world’s digital energy budget Posted: 11 Apr 2022 10:35 AM PDT A new spin on one of the 20th century's smallest but grandest inventions, the transistor, could help feed the world's ever-growing appetite for digital memory while slicing up to 5% of the energy from its power-hungry diet. |
| Light, oxygen turn waste plastics into useful benzoic acid Posted: 11 Apr 2022 09:54 AM PDT Chemists have discovered a way to use light and oxygen to upcycle polystyrene -- a type of plastic found in many common items -- into benzoic acid, a product stocked in undergraduate and high school chemistry labs and also used in fragrances, food preservatives, and other ubiquitous products. |
| Time-lapse images as the living brain responds to experiences Posted: 11 Apr 2022 09:07 AM PDT Researchers use manganese-enhanced magnetic resonance imaging to capture time-lapse images of the living brain. |
| Innovative technology will use smart sensors to ensure vaccine safety Posted: 11 Apr 2022 07:13 AM PDT A new study enables developers to determine vaccine safety via smart sensors that measure objective physiological parameters. |
| Light-powered microbes are super-producing chemical factories Posted: 11 Apr 2022 07:13 AM PDT Researchers have found that engineering the light-dependent proton pump rhodopsin into Escherichia coli redirects carbon flow from cellular metabolism to biosynthetic product generation. This approach of using light as an energy source can help improve the efficiency of target compound production and reduce CO2 emissions. |
| Electron lens formed by light: A new method for atomic-resolution electron microscopes Posted: 11 Apr 2022 07:13 AM PDT Researchers have proposed a new method to form an electron lens that will help reduce installation costs for electron microscopes with atomic resolution, proliferating their use. Instead of the electrostatic and magnetic fields employed in conventional electron lenses, they utilized a light field electron-lens. |
| Converting solar energy to electricity on demand Posted: 11 Apr 2022 07:13 AM PDT A new energy system that makes it possible to capture solar energy, store it for up to eighteen years and release it when and where it is needed has now taken the system a step further. After previously demonstrating how the energy can be extracted as heat, they have now succeeded in getting the system to produce electricity, by connecting it to a thermoelectric generator. |
| Want to be sustainable and cool? Choose fans more and AC less Posted: 08 Apr 2022 05:38 AM PDT A new study has found using indoor fans more often allows people to reduce their air conditioner use without changing how hot they feel, paving a way for reducing future energy use and greenhouse gas emissions. |
| Researchers engineer electrically tunable graphene devices to study rare physics Posted: 07 Apr 2022 11:20 AM PDT Scientists have developed a tunable graphene-based platform that allows for fine control over the interaction between light and matter in the terahertz (THz) spectrum to reveal rare phenomena known as exceptional points. The work could advance optoelectronic technologies to better generate, control and sense light and potentially communications, according to the researchers. They demonstrated a way to control THz waves, which exist at frequencies between those of microwaves and infrared waves. The feat could contribute to the development of 'beyond-5G' wireless technology for high-speed communication networks. |
| Researchers adapt technology made for astronomical observations to biomedical imaging Posted: 07 Apr 2022 07:11 AM PDT Researchers have captured images of multiple radionuclides in mice using astronomy technology. |
| Novel framework for classifying chaos and thermalization Posted: 05 Apr 2022 09:39 AM PDT The observation of new chaoticity-related time and length scales explains the breakdown of thermalization. |
