| New tool predicts changes that may make COVID variants more infectious Posted: 29 Sep 2021 01:38 PM PDT Researchers have created a novel framework that can predict with reasonable accuracy the amino-acid changes in the virus' spike protein that may improve its binding to human cells and confer increased infectivity to the virus. The tool could enable the computational surveillance of SARS-CoV-2 and provide advance warning of potentially dangerous variants with an even higher binding affinity potential. This can aid in the early implementation of public health measures to prevent the virus's spread and perhaps even may inform vaccine booster formulations. |

| What are ideal blood sugar levels for preventing repeat strokes, heart attacks? Posted: 29 Sep 2021 01:01 PM PDT Blood sugar control has always been important for people with diabetes when it comes to preventing a stroke. But a new study finds for people with diabetes who have a stroke, there may be an ideal target blood sugar range to lower the risk of different types of vascular diseases like a stroke or heart attack later on. |

| EMS ketamine use on agitated patients on cocaine increases intubation 5.75-fold, study finds Posted: 29 Sep 2021 06:26 AM PDT Patients with excited delirium often are administered ketamine by EMS before arriving at the hospital. Many of them are intoxicated or are using illicit substances, which may alter the properties of ketamine. A study explored if patients who received prehospital ketamine with concomitant substance intoxication have higher rates of subsequent intubation in the ER compared to those without confirmed substance usage. Among the results, cocaine intoxication had a statistically significant 5.75-fold increased rate of intubation. |
| AI-driven dynamic face mask adapts to exercise, pollution levels Posted: 29 Sep 2021 05:02 AM PDT Researchers have developed a dynamic respirator that modulates its pore size in response to changing conditions, such as exercise or air pollution levels, allowing the wearer to breathe easier when the highest levels of filtration are not required. |
| How high-fat diets allow cancer cells to go unnoticed Posted: 28 Sep 2021 04:38 PM PDT The immune system relies on cell surface tags to recognize cancer cells. Researchers discovered mice who ate high-fat diets produced less of these tags on their intestinal cells, suppressing the ability of immune cells to identify and eliminate intestinal tumors. The high-fat diet also reduced the presence of certain bacteria in the mice's gut, which normally helps maintain the production of these tags. |
| Life expectancy gap between black and white Americans closes nearly 50 percent in 30 years Posted: 28 Sep 2021 04:38 PM PDT Persistent gaps in life expectancy between Black and white Americans have been highlighted by the COVID-19 pandemic. Yet, this gap has narrowed by nearly 50 percent in three decades, largely due to improvements among Black Americans, according to a new study. |
| Study suggests R rate for tracking pandemic should be dropped in favour of 'nowcasts' Posted: 28 Sep 2021 04:37 PM PDT When the COVID-19 pandemic emerged in 2020, the R rate became well-known shorthand for the reproduction of the disease. Yet a new study suggests it's time for 'A Farewell to R' in favour of a different approach based on the growth rate of infection rather than contagiousness. |
| Study links air pollution to nearly 6 million preterm births around the world Posted: 28 Sep 2021 11:18 AM PDT Air pollution likely contributed to almost 6 million premature births and almost 3 million underweight babies in 2019, according to a global burden of disease study and meta-analysis that quantifies the effects of indoor and outdoor pollution around the world. |
| Children do not understand concept of others having false beliefs until age 6 or 7 Posted: 28 Sep 2021 09:13 AM PDT Understanding how others think, including the ability of other people to hold false beliefs, is important for social interaction. Called theory of mind, this ability has been thought to occur in children around age 4 years. New research suggests otherwise and shows that children do not understand others' false beliefs until age 6 or 7 years. Young children can pass theory-of-mind experiments using rudimentary concepts of seeing and knowing, without an understanding of mental representation. This work has implications for development and education. |
| The vicious circle of high academic achievement Posted: 28 Sep 2021 08:24 AM PDT For some teenagers, the new school year means reuniting with their friends. For others, it means an increase in anxiety and in the pressure to succeed and get good grades. According to researchers, this can lead to perfectionism and, in turn, to anxiety and depression. |
| Tracking muscle activity with clothes on your back Posted: 28 Sep 2021 08:02 AM PDT Researchers have developed a bioelectrical sensor that is convenient and low-cost. The sensor measures electromyography signals that are generated in muscles when they contract and are useful for studying muscle fatigue and recovery, and they have the potential to inform diagnosis and treatment of neuromuscular diseases. The biosensor, made of silver paste with a layer of gold nanoparticles on top, is directly integrated onto a piece of clothing. The result was a detector that was both conductive and nonirritating to the skin. |
