| Novel quantum effect discovered in naturally occurring graphene Posted: 06 Oct 2021 01:01 PM PDT Under special circumstances, the electrical resistance of a material can adopt a fixed value that is independent from the basic material properties and 'quantized'. This 'quantization' normally occurs within strong magnetic fields at very low temperatures when electrons move in two-dimensions. Now, a research team has succeeded in demonstrating this effect at low temperatures in the almost complete absence of a magnetic field in naturally occurring double-layer graphene, just two atoms thick. |
| New catalyst helps combine fuel cell, battery into one device Posted: 06 Oct 2021 01:01 PM PDT A team has developed a catalyst that can be used to both generate fuel and provide power. |
| Getting up to speed on the proton Posted: 06 Oct 2021 01:01 PM PDT A century ago, scientists first detected the proton in the atomic nucleus. Yet, much about its contents remains a mystery. Scientists report a new theory for understanding what's inside protons moving at the speed of light. |
| LEONARDO, the bipedal robot, can ride a skateboard and walk a slackline Posted: 06 Oct 2021 01:00 PM PDT LEO carves out a new type of locomotion somewhere between walking and flying. |
| Highly porous rocks responsible for Bennu's surprisingly craggy surface Posted: 06 Oct 2021 01:00 PM PDT Using data from NASA OSIRIS-REx mission, scientists concluded that asteroids with highly porous rocks, such as Bennu, should lack fine-grained material on their surfaces. |
| Dwarf planet Vesta a window to the early solar system Posted: 06 Oct 2021 11:34 AM PDT The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent articles use data from meteorites derived from Vesta to resolve the 'missing mantle problem' and push back our knowledge of the solar system to just a couple of million years after it began to form. |
| Tiny bubbles can be future treatment for inflammation Posted: 06 Oct 2021 10:49 AM PDT Scientists hope that tiny sacs of material excreted by cells -- so-called extracellular vesicles -- can be used to deliver drugs inside the body. Researchers now show that these nano-bubbles can transport protein drugs that reduce inflammation caused by different diseases. The technique shows promising results in animal models. |
| Catalysts found to convert carbon dioxide to fuel Posted: 06 Oct 2021 08:27 AM PDT The goal of tackling global warming by turning carbon dioxide into fuel could be one step closer with researchers using a supercomputer to identify a group of 'single-atom' catalysts that could play a key role. |
| Skyrmion research: Braids of nanovortices discovered Posted: 06 Oct 2021 08:26 AM PDT A team of scientists has discovered a new physical phenomenon: complex braided structures made of tiny magnetic vortices known as skyrmions. Skyrmions were first detected experimentally a little over a decade ago and have since been the subject of numerous studies, as well as providing a possible basis for innovative concepts in information processing that offer better performance and lower energy consumption. Furthermore, skyrmions influence the magnetoresistive and thermodynamic properties of a material. The discovery therefore has relevance for both applied and basic research. |
| Brain cell differences could be key to learning in humans and AI Posted: 06 Oct 2021 08:26 AM PDT Researchers have found that variability between brain cells might speed up learning and improve the performance of the brain and future AI. |
| Machine learning helps reveal cells’ inner structures in new detail Posted: 06 Oct 2021 08:26 AM PDT Scientists have created a set of tools to make annotated 3D images of cells, showing the relationships between different organelles. |
| Intelligence emerging from random polymer networks Posted: 06 Oct 2021 07:44 AM PDT A team of researchers assembled a sulfonated polyaniline (SPAN) organic electrochemical network device (OEND) for use in reservoir computing. SPAN was deposited on gold electrodes which formed a disordered network providing humidity-dependent electrical properties. The SPAN OEND was tested for reservoir computing using benchmark tasks and spoken-digit classification, which showed 70% accuracy. The device has the potential to be applied to a wide range of artificial intelligence tasks including speech recognition. |
| Large scale solar parks cool surrounding land Posted: 05 Oct 2021 09:48 AM PDT Researchers studying two solar parks, situated in arid locations, found they produced 'cool islands' extending around 700 meters from the solar park boundaries. The temperature of surrounding land surface was reduced by up to 2.3 degrees at 100 meters away from the solar park, with the cooling effects reducing exponentially to 700 meters. This new discovery is important as it shows the solar park could impact ecological processes, including productivity, decomposition, and ultimately the carbon balance, in the surrounding landscape. |
| New type of magnetism unveiled in an iconic material Posted: 05 Oct 2021 09:47 AM PDT Scientists have made a path-breaking discovery in strontium ruthenate -- with potential for new applications in quantum electronics. |
| Structure formation in mini-organs Posted: 05 Oct 2021 07:18 AM PDT The development of alveoli in organoids derived from mammary-gland tissue follows the same physical principles as the formation of discrete droplets in a water jet. |
| Making self-driving cars human-friendly Posted: 04 Oct 2021 05:34 PM PDT Automated vehicles could be made more pedestrian-friendly thanks to new research which could help them predict when people will cross the road. Scientists investigating how to better understand human behavior in traffic say that neuroscientific theories of how the brain makes decisions can be used in automated vehicle technology to improve safety and make them more human-friendly. |
