| Rapid adaptation of deep learning teaches drones to survive any weather Posted: 05 May 2022 05:56 AM PDT Neural-Fly technology could one day build the future of package delivery drones and flying cars. |
| How MRI could revolutionize heart failure diagnosis Posted: 05 May 2022 05:56 AM PDT Until now, the best way of diagnosing heart failure has been an invasive assessment, but it carries risks for patients. Non-invasive echocardiogram, which is based on ultrasound, are usually used instead, but they are wrong in up to 50 per cent of cases. The new study shows how magnetic resonance imaging (MRI) is superior to echocardiography for diagnosing heart failure, as well as being a powerful tool to predict patient outcomes, including death. |
| Quantum mechanics could explain why DNA can spontaneously mutate Posted: 05 May 2022 05:56 AM PDT The molecules of life, DNA, replicate with astounding precision, yet this process is not immune to mistakes and can lead to mutations. Using sophisticated computer modelling, a team of physicists and chemist have shown that such errors in copying can arise due to the strange rules of the quantum world. |
| New technology reduces heavy-duty diesel emissions to meet stringent CARB 2027 NOx requirements Posted: 04 May 2022 02:08 PM PDT Engineers have demonstrated the effectiveness of new technology to cut diesel emissions. The advancement successfully reduced heavy-duty diesel engine nitrogen oxide (NOx) emissions to meet the California Air Resources Board (CARB) 2027 standards. |
| The quest for an ideal quantum bit Posted: 04 May 2022 10:08 AM PDT Scientists have developed a qubit platform formed by freezing neon gas into a solid, spraying electrons from a light bulb's filament onto it, and trapping a single electron there. This system shows great promise as an ideal building block for quantum computers. |
| Correct dosage for ultraviolet disinfection against COVID Posted: 04 May 2022 08:04 AM PDT When the COVID-19 pandemic emerged, ultraviolet radiation became one of the go-to methods for preventing the spread of the SARS-CoV-2 virus, along with facemasks, hand sanitizer and social distancing. The problem: There was little research showing what UV dosage kills the virus. In a new study, researchers lay the foundation for health standards about what offers true disinfection. |
| Remote programming of cardiac implantable devices is safe for MRI scan, study suggests Posted: 04 May 2022 08:04 AM PDT More than 60 million magnetic resonance imaging (MRI) scans are performed worldwide each year, but imaging for the millions of patients with cardiac implantable electronic devices (CIEDs) such as pacemakers is a logistical challenge, because of concerns with how the magnetic field affects the implants. Now, a newly published study reveals safe and effective reprogramming of these devices is possible, even from a remote location. |
| A new wearable technology -- for plants Posted: 04 May 2022 07:09 AM PDT Plants can't speak up when they are thirsty. And visual signs, such as shriveling or browning leaves, don't start until most of their water is gone. To detect water loss earlier, researchers have created a wearable sensor for plant leaves. The system wirelessly transmits data to a smartphone app, allowing for remote management of drought stress in gardens and crops. |
| Taste of the future: Robot chef learns to 'taste as you go' Posted: 04 May 2022 05:26 AM PDT A robot 'chef' has been trained to taste food at different stages of the chewing process to assess whether it's sufficiently seasoned. |
| Researchers devise cheaper, faster way to continuously produce amines Posted: 04 May 2022 05:26 AM PDT Chemical engineering researchers have developed a faster, less expensive technique for producing hindered amines -- a class of chemicals used as building blocks in products ranging from pharmaceuticals and agrochemicals to detergents and organic light emitting diodes. |
| Urbanization linked to poor ecological knowledge, less environmental action Posted: 04 May 2022 05:26 AM PDT A new study highlights a sharp contrast between urban and suburban ways of thinking about coastal ecosystems. The authors of the study used statistical and cognitive science techniques to analyze data from a survey of 1,400 residents across the U.S. East Coast. Their results showed that surveyed residents of urban centers often held a more simplistic, and less realistic, understanding of coastal ecosystems than residents in suburban areas. The research also uncovered a lower propensity to take pro-environmental actions among urban populations. |
| Posted: 02 May 2022 02:08 PM PDT A cross-disciplinary team has demonstrated a major breakthrough in using automated synthesis to discover new molecules for organic electronics applications. Using automated synthesis, the team was able to rapidly scan through a library of molecules with precisely defined structures, thereby uncovering, via single-molecule characterization experiments, a new mechanism for high conductance. |
