| Physicists embark on a hunt for a long-sought quantum glow Posted: 26 Apr 2022 01:26 PM PDT Researchers say they've found a way to significantly increase the probability of observing the Unruh effect, a 'quantum glow' phenomenon that was first proposed in the 1970s. |
| Posted: 26 Apr 2022 01:25 PM PDT Novel system could lead to catalysts based on cheaper, more abundant nickel rather than more expensive precious metals. |
| AI may detect earliest signs of pancreatic cancer Posted: 26 Apr 2022 12:37 PM PDT An artificial intelligence (AI) tool can accurately predicted who would develop pancreatic cancer based on what their CT scan images looked like years prior to being diagnosed with the disease. The findings may help prevent death through early detection of one of the most challenging cancers to treat. |
| COVID-19 lockdown measures affect air pollution from cities differently Posted: 26 Apr 2022 12:37 PM PDT Seizing on a natural experiment created by restricted travel, researchers combine a network model with air pollution data before and during outbreaks. |
| Existing infrastructure will be unable to support future demand for high-speed internet Posted: 26 Apr 2022 12:37 PM PDT Researchers have shown that the UK's existing copper network cables can support faster internet speeds, but only to a limit. They say additional investment is urgently needed if the government is serious about its commitment to making high-speed internet available to all. |
| Measuring the 'wettability' of graphene and other 2D materials Posted: 26 Apr 2022 12:36 PM PDT Measuring the 'wettability' of graphene and other 2D materials. Microscopic understanding of wettability can be achieved at the molecular level using 'vibrational sum-frequency generation spectroscopy' (VSFG). |
| Researchers develop a paper-thin loudspeaker Posted: 26 Apr 2022 12:36 PM PDT Researchers created an ultrathin loudspeaker that can turn any rigid surface into a high-quality, active audio source. The fabrication process can enable the thin-film devices to be produced at scale. |
| Best version of exosuit to take strain off the back Posted: 26 Apr 2022 12:36 PM PDT A research team studies exosuits, a wearable mobile machine that allows for limb movement with increased strength and endurance. |
| Classifying exoplanet atmospheres opens new field of study Posted: 26 Apr 2022 07:17 AM PDT An international team of researchers examined data for 25 exoplanets and found some links among the properties of the atmospheres, including the thermal profiles and chemical abundances in them. These findings will help establish a generalized theory of planet formation which will improve our understanding of all planets, including the Earth. |
| Researchers unveil a highly efficient means to reverse magnetization with spin currents Posted: 26 Apr 2022 07:17 AM PDT Researchers have established a low-cost method of magnetization reversal on perpendicularly magnetized ferromagnets. Not needing an external magnetic field, the method brings reverse magnetization closer to commercial viability. |
| Immersive VR: Empowering kids to survive in fire, flood, and war Posted: 26 Apr 2022 07:17 AM PDT When you live in the driest State in the driest country in the world, bushfires are an unfortunate, and all-too-regular part of life. Learning how to survive such emergencies is important for all people, but especially for our youngest citizens. |
| Scientists use recycled glass waste as sand replacement in 3D printing Posted: 26 Apr 2022 07:17 AM PDT Researchers have developed the capability to use recycled glass in 3D printing, opening doors to a more environmentally sustainable way of building and construction. |
| Learning chemical networks give life a chiral twist Posted: 26 Apr 2022 07:17 AM PDT A study shows that the preference of biological molecules for left or right-handedness -- a hallmark of living matter -- could emerge spontaneously as prebiotic chemical networks adapt to optimize energy harvesting. The proposed mechanism of symmetry breaking is general and can apply to other transitions in living matter that lead to increased complexity. |
| Microrobot collectives display versatile movement patterns Posted: 26 Apr 2022 07:16 AM PDT Collective behavior and swarm patterns are found everywhere in nature. Robots can also be programmed to act in swarms. Researchers have developed collectives of microrobots, which they can move in every formation they wish. |
| New graphite based rapid sensor chip for real-time theophylline monitoring Posted: 26 Apr 2022 07:16 AM PDT Although theophylline (THO) is effective in treating respiratory problems and inflammation, the drug can be toxic if taken above certain limits. This demands accurate and rapid sensing devices that can closely monitor THO levels in patients. Therefore, scientists have now designed a paper-based THO sensor with a response time of 3 seconds. This new sensor is highly selective and sensitive. It has also been successfully tested using whole bovine blood. |
