| Defying a 150-year-old rule for phase behavior Posted: 18 Sep 2020 03:51 PM PDT Today, researchers are defying a classical theory from American physicist Josiah Willard Gibbs, with proof of a five-phase equilibrium, something that many scholars considered impossible.      |
| Shape matters for light-activated nanocatalysts Posted: 18 Sep 2020 03:51 PM PDT Points matter when designing nanoparticles that drive important chemical reactions using the power of light, according to recent research. |
| New design principles for spin-based quantum materials Posted: 18 Sep 2020 09:22 AM PDT A new design criteria for enhancing the spin lifetime of a class of quantum materials could support Internet of Things devices and other resource-intensive technologies. |
| Solar storm forecasts for Earth improved with help from the public Posted: 18 Sep 2020 08:33 AM PDT Scientists used observations recorded by members of the public to increase accuracy of computer model predictions of when harmful CMEs will hit Earth. |
| Biologists create new genetic systems to neutralize gene drives Posted: 18 Sep 2020 08:33 AM PDT Addressing concerns about gene drive releases in the wild, scientists have developed two new genetic systems that halt or eliminate gene drives after release. Created in fruit flies, the e-CHACRs and ERACRs are powerful gene drive control mechanisms that were meticulously developed and tested at the genetic and molecular levels. |
| Engineers produce a fisheye lens that's completely flat Posted: 18 Sep 2020 08:33 AM PDT Engineers have designed a wide-angle lens that is completely flat. It is the first flat fisheye lens to produce crisp, 180-degree panoramic images. |
| Researchers develop simple method to 3D print milk products Posted: 18 Sep 2020 07:42 AM PDT Additive free, multimaterial 3D printing is achieved for milk-based products without temperature control. |
| Promising computer simulations for stellarator plasmas Posted: 18 Sep 2020 07:42 AM PDT The turbulence code GENE (Gyrokinetic Electromagnetic Numerical Experiment), has proven to be very useful for the theoretical description of turbulence in the plasma of tokamak-type fusion devices. Extended for the more complex geometry of stellarator-type devices, computer simulations with GENE now indicate a new method to reduce plasma turbulence in stellarator plasmas. This could significantly increase the efficiency of a future fusion power plant. |
| VLBA makes first direct distance measurement to magnetar Posted: 18 Sep 2020 07:42 AM PDT Using the VLBA, astronomers have made the first direct geometric measurement of the distance to a magnetar. This precision measurement to one of the most magnetic objects in the Universe could help scientists determine if such objects are responsible for generating the mysterious Fast Radio Bursts. |
| Posted: 18 Sep 2020 07:42 AM PDT Free electron X-ray lasers deliver intense ultrashort pulses of x-rays, which can be used to image nanometer-scale objects in a single shot. When the x-ray wavelength is tuned to an electronic resonance, magnetization patterns can be made visible. When using increasingly intense pulses, however, the magnetization image fades away. The mechanism responsible for this loss in resonant magnetic scattering intensity has now been clarified. |
| Nano-microscope gives first direct observation of the magnetic properties of 2D materials Posted: 18 Sep 2020 06:05 AM PDT Widefield nitrogen-vacancy microscope solves problem of there being no way to tell exactly how strongly magnetic a 2D material was. |
| Supercooled water is a stable liquid, scientists show for the first time Posted: 17 Sep 2020 03:04 PM PDT First-ever measurements provide evidence that extremely cold supercooled water exists in two distinct structures that co-exist and vary in proportion dependent on temperature. |
| New mathematical tool can select the best sensors for the job Posted: 17 Sep 2020 03:04 PM PDT In the 2019 Boeing 737 Max crash, the recovered black box from the aftermath hinted that a failed pressure sensor may have caused the ill-fated aircraft to nose dive. This incident and others have fueled a larger debate on sensor selection, number and placement to prevent the reoccurrence of such tragedies. Researchers have now developed a comprehensive mathematical framework that can help engineers make informed decisions about which sensors to use. |
| Shedding light on the development of efficient blue-emitting semiconductors Posted: 17 Sep 2020 10:55 AM PDT Scientists have discovered a new alkali copper halide, Cs5Cu3Cl6I2, that emits pure blue light. The combination of the two halide ions, chloride and iodide, gives the material a crystalline structure made of zigzag chains and peculiar properties that result in highly efficient photoluminescence. This novel compound could be readily used to produce relatively inexpensive and eco-friendly white LEDs and reduce the energy used in the generation of everyday artificial light. |
| The brain's memory abilities inspire AI experts in making neural networks less 'forgetful' Posted: 17 Sep 2020 10:55 AM PDT Artificial intelligence (AI) experts report that they have successfully addressed what they call a 'major, long-standing obstacle to increasing AI capabilities' by drawing inspiration from a human brain memory mechanism known as 'replay.' |
| Posted: 17 Sep 2020 09:28 AM PDT Scientists have recently developed an all-optical ultrafast imaging system with high spatial and temporal resolutions, as well as a high frame rate. Because the method is all-optical, it's free from the bottlenecks that arise from scanning with mechanical and electronic components. |
| Generation of three-dimensional heart organoids Posted: 16 Sep 2020 06:42 AM PDT Researchers engineered three-dimensional functional heart organoids resembling the developing heart. By exposing mouse embryonic stem cells to two key proteins during heart development, the researchers were able to form heart organoids with structural, functional, and molecular similarities to the embryonic heart during development. This method could be used to study heart development and to screen for novel drugs against heart disease. |
