| Juno and Hubble data reveal electromagnetic 'tug-of-war' lights up Jupiter’s upper atmosphere Posted: 03 Feb 2022 05:36 AM PST New space research has revealed a complex 'tug-of-war' lights up aurorae in Jupiter's upper atmosphere. The study describes the delicate current cycle driven by Jupiter’s rapid rotation and the release of sulphur and oxygen from volcanoes on its moon, Io. |
| People prefer interacting with female robots in hotels, study finds Posted: 03 Feb 2022 05:35 AM PST People are more comfortable talking to female rather than male robots working in service roles in hotels, according to new research. The study, which surveyed about 170 people on hypothetical service robot scenarios, also found that the preference was stronger when the robots were described as having more human features. |
| A new, nanoscale, 3D structure to control light Posted: 02 Feb 2022 01:27 PM PST Metamaterials, made up of small, repeated structures, engineered to produce desired interactions with light or sound waves, can improve optical devices used in telecommunications, imaging and more. But the functionality of the devices can be limited by the corresponding design space. |
| Scientists develop 'exceptional' surface to explore exotic physics Posted: 02 Feb 2022 12:38 PM PST By demonstrating exceptional control of an open optical system, an international research team has provided a path to experimentally measure and test exotic phenomena and gain insights into new physics with exquisite sensitivity. |
| Researchers set record by preserving quantum states for more than 5 seconds Posted: 02 Feb 2022 12:38 PM PST A team of researchers has maintained a qubit coherence time for a record five seconds. The qubits are made from silicon carbide, widely found in lightbulbs, electric vehicles and high voltage electronics. |
| Astronomers offer theory about mysterious location of massive stars Posted: 02 Feb 2022 12:38 PM PST Astronomers have found an explanation for the strange occurrence of massive stars located far from their birthplace in the disk of our Milky Way Galaxy. |
| Quick COVID breathalyzer could allow mass screening in public places Posted: 02 Feb 2022 11:31 AM PST Researchers have developed a prototype 'breathalyzer' that can sensitively and accurately diagnose COVID-19, even in asymptomatic individuals, in less than 5 minutes. |
| Scientists develop insect-sized flying robots with flapping wings Posted: 02 Feb 2022 11:30 AM PST A new drive system for flapping wing autonomous robots has been developed, using a new method of electromechanical zipping that does away with the need for conventional motors and gears. |
| Engineers develop surgical 'duct tape' as an alternative to sutures Posted: 02 Feb 2022 11:30 AM PST Engineers have developed a kind of surgical 'duct tape.' The strong, flexible, and biocompatible sticky patch can be applied to biological tissues and organs to help seal tears and wounds. |
| Shocked zircon find a 'one-off gift' from Mars Posted: 02 Feb 2022 11:30 AM PST Researchers studying a Martian meteorite have found the first evidence of high-intensity damage caused by asteroid impact, in findings that have implications for understanding when conditions suitable for life may have existed on early Mars. |
| Novel method simulates tens of thousands of bubbles in foamy flows Posted: 02 Feb 2022 11:30 AM PST Bubbles aren't just for bath time. Bubbles, specifically bubbles in foamy flows, are critical for many industrial processes, including the production of food and cosmetics and drug development and delivery. But the behavior of these foamy flows is notoriously difficult to compute because of the sheer number of bubbles involved. Previous attempts to simulate foamy flows have relied on the time-consuming and computationally expensive process of tracking the bubbles by color-coating each individual bubble in the foam. This limited simulations to just a few dozen bubbles, instead of the thousands to millions in real foams. Now, researchers have developed a new way to simulate tens of thousands of bubbles in foamy flows, breaking the computational complexity of this long-standing process. |
| Testing the effectiveness of KN95 and surgical mask 'fit hacks' Posted: 02 Feb 2022 11:30 AM PST Researchers have tested a variety of popular hacks for improving the fit of KN95 and surgical masks, and found that while some hacks do improve fit, they can also come at the cost of the wearer's comfort. |
| Scientists engineer new material that can absorb and release enormous amounts of energy Posted: 02 Feb 2022 10:47 AM PST A team of researchers recently announced that they had engineered a new rubber-like solid substance that has surprising qualities. It can absorb and release very large quantities of energy. And it is programmable. Taken together, this new material holds great promise for a very wide array of applications, from enabling robots to have more power without using additional energy, to new helmets and protective materials that can dissipate energy much more quickly. |
| Novel chemical glucose sensing method based on boronic acids and graphene foam Posted: 02 Feb 2022 10:47 AM PST Researchers have developed a new glucose sensor that is cheaper and more robust than current systems. |
| The puzzle of the 'lost' angular momentum Posted: 02 Feb 2022 08:17 AM PST A research team succeeds in solving a decade-old physical puzzle: the question of the fate of angular momentum during the ultrafast demagnetization of nickel crystals by laser light. |
