| In Einstein's footsteps and beyond Posted: 27 Apr 2022 12:41 PM PDT Physicists are re-examining the foundations of quantum physics from the perspective of momentum and exploring what happens when the momentum of light is reduced to zero. |
| New device: Tallest height of any known jumper, engineered or biological Posted: 27 Apr 2022 12:41 PM PDT A mechanical jumper is capable of achieving the tallest height -- roughly 100 feet (30 meters) -- of any jumper to date, engineered or biological. The feat represents a fresh approach to the design of jumping devices and advances the understanding of jumping as a form of locomotion. |
| The instability at the beginning of the solar system Posted: 27 Apr 2022 12:40 PM PDT Michigan State University's Seth Jacobson and colleagues in China and France have unveiled a new theory that could help solve a galactic mystery of how our solar system evolved. Specifically, how did the gas giants -- Jupiter, Saturn, Uranus and Neptune -- end up where they are, orbiting the sun like they do? The research also has implications for how terrestrial planets such as Earth were formed and the possibility that a fifth gas giant lurks 50 billion miles out into the distance. |
| Posted: 27 Apr 2022 11:06 AM PDT Scientists have developed an acid-based solvent that simplifies carbon nanotube processing in a way that's less toxic and easy to scale up for industrial applications. |
| Nanoplastic particles love company: Researchers analyze polyethylene degradation in environment Posted: 27 Apr 2022 09:42 AM PDT Polyethylene accounts for nearly one-third of the world's plastic waste. An interdisciplinary team has now investigated the progressive degradation of polyethylene in the environment for the first time. Although the degradation process leads to fragmentation into ever smaller particles, isolated nanoplastic particles are rarely found in the environment. The reason is that such decay products do not like to remain on their own, but rather attach rapidly to larger colloidal systems that occur naturally in the environment. |
| Human skin has evolved to allow maximum durability and flexibility Posted: 27 Apr 2022 08:57 AM PDT Human skin has evolved to allow maximum durability and flexibility, according to new research. |
| Electronic skin anticipates and perceives touch from different directions for the first time Posted: 27 Apr 2022 08:57 AM PDT Scientists have developed a new approach for miniaturization of soft ultra-compact and highly integrated sensor units for directional tactile sensitivity in e-skin systems. |
| Plug-and-play organ-on-a-chip can be customized to the patient Posted: 27 Apr 2022 08:57 AM PDT Researchers have developed a model of human physiology in the form of a multi-organ chip consisting of engineered human heart, bone, liver, and skin that are linked by vascular flow with circulating immune cells, to allow recapitulation of interdependent organ functions. The researchers have essentially created a plug-and-play multi-organ chip, which is the size of a microscope slide, that can be customized to the patient. |
| Supernova reveals secrets to astronomers Posted: 27 Apr 2022 08:57 AM PDT An international group of astronomers has used observations to unlock a puzzling mystery about a stellar explosion discovered several years ago and evolving even now. The results will help astronomers better understand the process of how massive stars live and die. |
| Glimpse inside a graphene sandwich Posted: 27 Apr 2022 07:06 AM PDT In the search for novel types of superconductors -- phases of matter that that conduct electric current without loss -- scientists are investigating materials that consist of multiple layers. A team has studied in detail the properties of a system of three twisted graphene layers and gained important insights into its properties. |
| New cocoa processing method produces fruitier, more 'flowery' dark chocolate Posted: 27 Apr 2022 07:05 AM PDT Producing chocolate, one of the world's most beloved sweets, is a multistep process beginning with freshly harvested cocoa beans. People have been experimenting with chocolate-making for millennia, and even today, new methods are still being introduced. Now, researchers have found that an alternative processing step called 'moist incubation' results in a fruitier, more flowery-tasting dark chocolate than the conventional fermentation process. |
| Solar beats nuclear at many potential settlement sites on Mars Posted: 27 Apr 2022 07:05 AM PDT While most missions to the moon and other planets rely upon solar power, scientists have assumed that any extended surface mission involving humans would require a more reliable source of energy: nuclear power. Improvements in photovoltaics are upending this calculus. A new study concludes that a solar power system would weigh less than a nuclear system, and would be sufficient to power a colony at sites over nearly half the surface. |
| Posted: 27 Apr 2022 07:05 AM PDT Hydrogen production using sunlight energy (solar-water splitting) has gained much attention in the quest to move towards carbon-neutral technologies. If chemical products with applications in the health and food industries could be produced at the same time as hydrogen, this would help reduce the cost of solar-water splitting, as well as increasing the technology's range of applications. |
| 3D bimodal photoacoustic ultrasound imaging to diagnose peripheral vascular diseases Posted: 27 Apr 2022 07:05 AM PDT A research team has developed a bimodal photoacoustic/ ultrasound imaging technology for the human foot. |
| New mechanism to transfer chirality between molecules in the nanoscale field Posted: 27 Apr 2022 07:04 AM PDT New research describes how the modulation of the geometry of a helical reactor at a macroscopic level enables controlling the sign of chirality of a process at a nanometric scale, an unprecedented discovery to date in the scientific literature. |
| Lignin-based jet fuel packs more power for less pollution Posted: 27 Apr 2022 07:04 AM PDT An experimental plant-based jet fuel could increase engine performance and efficiency, while dispensing with aromatics, the pollution-causing compounds added to conventional fuels, according to new research. |
| Disposable masks could be used to improve concrete Posted: 27 Apr 2022 07:04 AM PDT With the pervasive single-use masks during the pandemic now presenting an environmental problem, researchers have demonstrated the idea of incorporating old masks into a cement mixture to create stronger, more durable concrete. |
