| Moments of silence point the way towards better superconductors Posted: 20 Dec 2021 09:06 AM PST High-precision measurements have provided important clues about processes that impair the efficiency of superconductors. Future work building on this research could offer improvements in a range of superconductor devices, such quantum computers and sensitive particle detectors. |
| Using sparse data to predict lab earthquakes Posted: 17 Dec 2021 02:28 PM PST A machine-learning approach developed for sparse data reliably predicts fault slip in laboratory earthquakes and could be key to predicting fault slip and potentially earthquakes in the field. |
| Mirror-image peptides form ‘rippled sheet’ structure predicted in 1953 Posted: 17 Dec 2021 09:38 AM PST By mixing a small peptide with equal amounts of its mirror image, scientists have created an unusual protein structure known as a 'rippled beta sheet' and obtained images of it using x-ray crystallography. The rippled sheet is a distinctive variation on the pleated beta sheet, which is a well-known structural motif found in thousands of proteins, including important disease-related proteins. Linus Pauling and Robert Corey described the rippled beta sheet in 1953, two years after introducing the concept of the pleated beta sheet. |
| Using ergonomics to reduce pain from technology use Posted: 17 Dec 2021 09:38 AM PST The use of smartphones, tablets and laptops has become commonplace throughout the world and has been especially prevalent among college students. Recent studies have found that college students have higher levels of screen time, and they utilize multiple devices at higher rates compared to previous generations. |
| Magnetic ‘hedgehogs’ could store big data in a small space Posted: 17 Dec 2021 08:32 AM PST Atomic-scale magnetic patterns resembling a hedgehog's spikes could result in hard disks with massively larger capacities than today's devices, a new study suggests. The finding could help data centers keep up with the exponentially increasing demand for video and cloud data storage. |
| Voluntary pledges could cut utility GHG emissions by a third Posted: 17 Dec 2021 08:32 AM PST An analysis of pledges made by many of the largest U.S. electric utilities to reduce greenhouse gas (GHG) emissions suggests that pledged reductions could reduce power sector emissions by a third as compared to 2018 levels. The study also found that about one-seventh of the cuts utilities have promised are reductions they would have to make anyway due to existing state requirements. |
| Understanding cobalt’s human cost Posted: 17 Dec 2021 08:32 AM PST After studying the impacts of mining cobalt -- a common ingredient in lithium-ion batteries -- on communities in Africa's Democratic Republic of the Congo (DRC), an interdisciplinary team of researchers is calling for more data into how emerging technologies affect human health and livelihoods. |
| Redrawing the lines: Growing inexpensive, high-quality iron-based superconductors Posted: 17 Dec 2021 07:28 AM PST Superconducting materials show zero electrical resistance at low temperatures, which allows them to conduct 'supercurrents' without dissipation. Recently, a group of scientists developed an inexpensive, scalable way to produce high-temperature superconductors using 'grain boundary engineering' techniques. The new method could help develop stronger, inexpensive, and high operating temperature superconductors with impactful technological applications. |
| Rollercoaster of emotions: Exploring emotions with virtual reality Posted: 17 Dec 2021 07:28 AM PST To the left and right, the landscape drifts idly by, the track in front of you. Suddenly, a fire. The tension builds. The ride reaches its highest point. Only one thing lies ahead: the abyss. Plummeting down into the depths of the earth. These are scenes of a rollercoaster ride as experienced by participants in a recent study. However, not in real life, but virtually, with the help of virtual reality (VR) glasses. The aim of the research was to find out what happens in participants' brains while they experience emotionally engaging situations. |
| New research sheds light on how ultrasound could be used to treat psychiatric disorders Posted: 17 Dec 2021 07:27 AM PST A new study has shown how the brain gives credit to events, along with how transcranial ultrasound (TUS) can disrupt this process. While currently developed in an animal model, this line of research and the use of TUS could one day be applied to clinical research to tackle conditions such as addiction. |
| Perovskite solar cell with ultra-long stability Posted: 17 Dec 2021 07:22 AM PST Perovskites are the great hope for further increasing the efficiency of solar modules in the future. Until now, their short service life has been considered the biggest hurdle to their practical use, but this could soon change. Researchers now present a variant that stands out for its stability. |
| Posted: 16 Dec 2021 12:00 PM PST Researchers have pioneered a new fabrication technique that enables them to produce low-voltage, power-dense, high endurance soft actuators for an aerial microrobot. These artificial muscles vastly improve the robot's payload and allow it to achieve best-in-class hovering performance. |
| Demonstrating Feshbach resonances between a single ion and ultracold atoms Posted: 16 Dec 2021 11:59 AM PST A team has demonstrated magnetic Feshbach resonances between a single barium ion and lithium atoms at near absolute zero temperature. The researchers found that depending on the strength of the external magnetic field, the expansion of the ion and atoms can be controlled. |
| Nanoparticle therapeutic enhances cancer immunotherapy Posted: 16 Dec 2021 11:59 AM PST Researchers have discovered that a nanoparticle therapeutic enhances cancer immunotherapy and is a possible new approach in treating malignant pleural effusion (MPE). MPE is the accumulation of fluid between the chest wall and lungs and is accompanied by malignant cells and/or tumors. |
| Fabricating stable, high-mobility transistors for next-generation display technologies Posted: 16 Dec 2021 11:58 AM PST The trade-off between carrier mobility and stability in amorphous oxide semiconductor-based thin film transistors (TFTs) has been finally overcome by researchers in an ingeniously fabricated indium tin zinc oxide TFT. This could pave the way for the design of display technologies that are cheaper than current silicon-based technologies. |
| New smart-roof coating enables year-round energy savings Posted: 16 Dec 2021 11:50 AM PST Scientists have developed an all-season smart-roof coating that keeps homes warm during the winter and cool during the summer -- without consuming natural gas or electricity. Research findings point to a groundbreaking technology that outperforms commercial cool-roof systems in energy savings. |
| ‘Gentrification’ changes the personality make-up of cities in just a few years Posted: 15 Dec 2021 05:41 PM PST A massive study of almost two million US residents reveals rising housing costs may drive increases in 'openness' of character among both old and new inhabitants of a city -- all in well under a decade. |
| How to transform vacancies into quantum information Posted: 15 Dec 2021 05:41 PM PST Researchers have made a breakthrough that should help pave the way for greatly improved control over the formation of quantum bits or qubits, the basic unit of quantum information technology. |
