| Posted: 02 Sep 2021 02:48 PM PDT Researchers have developed an online tool to help medical staff quickly determine which COVID-19 patients will need help breathing with a ventilator. The tool, developed through analysis of CT scans from nearly 900 COVID-19 patients diagnosed in 2020, was able to predict ventilator need with 84 percent accuracy. |
| Optimal lifting of COVID-19 restrictions would follow pace of vaccination, study suggests Posted: 02 Sep 2021 02:47 PM PDT A new analysis suggests that, in order to boost freedoms and protect against overwhelming new waves of COVID-19, the pace at which restrictions to reduce spread are lifted must be directly tied to the pace of vaccination. |
| Scientists create a labor-saving automated method for studying electronic health records Posted: 02 Sep 2021 09:51 AM PDT A new, automated, artificial intelligence-based algorithm can learn to read patient data from electronic health records. In a side-by-side comparison, scientists showed that their method accurately identified patients with certain diseases as well as the traditional, 'gold-standard' method, which requires much more manual labor to develop and perform. |
| These geckos crash-land on rainforest trees but don't fall, thanks to their tails Posted: 02 Sep 2021 09:51 AM PDT Many arboreal lizards leap and glide from tree to tree, but what if they can't glide to a gentle, four-point landing? Researchers documented many such leaps of the common house gecko, and found that they often hit trees headfirst and rebounded violently. Their recovery strategy -- grab on with the back feet and leverage their tail to prevent falling. The team created a soft robot with reactive tail that could replicate this previously unknown fall-arresting behavior. |
| Posted: 02 Sep 2021 09:50 AM PDT Many electronic devices today are dependent on semiconductor logic circuits based on switches hard-wired to perform predefined logic functions. Physicists have developed a novel molecular memristor, or an electronic memory device, that has exceptional memory reconfigurability. |
| Anatomy of the impact of a protostellar jet in the Orion Nebula Posted: 02 Sep 2021 09:50 AM PDT Researchers have uncovered the physical and chemical effects of the impact of a protostellar jet in the interior of the Orion Nebula. The observations show evidence of compression and heating produced by the shock front, and the destruction of dust grains, which cause a dramatic increase in the gas phase abundance of the atoms of iron, nickel, and other heavy elements in the Orion Nebula. |
| Quantum emitters: Beyond crystal clear to single-photon pure Posted: 02 Sep 2021 09:49 AM PDT A research team has developed a technique that can isolate the desired quality emitter by reducing the noise surrounding the target with what they have dubbed a 'nanoscale focus pinspot.' |
| New molecular device has unprecedented reconfigurability reminiscent of brain plasticity Posted: 01 Sep 2021 04:14 PM PDT Researchers describe a novel molecular device with exceptional computing prowess. Reminiscent of the plasticity of connections in the human brain, the device can be reconfigured on the fly for different computational tasks by simply changing applied voltages. Furthermore, like nerve cells can store memories, the same device can also retain information for future retrieval and processing. |
| Machine learning tool detects the risk of genetic syndromes in children with diverse backgrounds Posted: 01 Sep 2021 04:14 PM PDT With an average accuracy of 88%, a deep learning technology offers rapid genetic screening that could accelerate the diagnosis of genetic syndromes, recommending further investigation or referral to a specialist in seconds, according to a new study. Trained with data from 2,800 pediatric patients from 28 countries, the technology also considers the face variability related to sex, age, racial and ethnic background. |
| Physicists find 'magnon' origins in 2D magnet Posted: 01 Sep 2021 01:11 PM PDT Physicists have confirmed the topological origins of magnons, magnetic features they discovered three years ago in a 2D material that could prove useful for spintronics. |
| Long-lasting disinfectant promises to help fight pandemics Posted: 01 Sep 2021 11:27 AM PDT Researchers have developed a nanoparticle-based disinfectant that can continuously kill viruses on a surface for up to seven days -- a discovery that could be a powerful weapon against COVID-19 and other emerging pathogenic viruses. |
| Switching to green cleaning reduces users’ exposure to potentially harmful chemicals Posted: 01 Sep 2021 06:01 AM PDT Teenagers from California's Salinas Valley worked alongside scientists on research showing that switching to green cleaning products can reduce users' exposure to a variety of toxic chemicals. The high school team also created a series of animated public service announcements, in both English and Spanish, to share the results with their community. |
