| Early warning system for COVID-19 gets faster through wastewater detection and tracing Posted: 04 Jun 2021 10:54 AM PDT A new research paper builds on previous research of COVID-19 testing in municipal sewer systems and subsequent tracing the virus back to the source by more accurately modelling a system's treelike network of one-way pipes and manholes, and by speeding up the detection/tracing process through automatic sensors installed in specific manholes, chosen according to an easier-to-use algorithm. |
| Gene protection for COVID-19 identified Posted: 04 Jun 2021 10:54 AM PDT A genetic link has been discovered explaining why some people catch COVID but don't get sick. The gene is found three times as often in people who are asymptomatic. This is the first clear evidence of genetic resistance because the study compared severely affected people with an asymptomatic COVID group and used next generation sequencing to focus in detail and at scale on the HLA genes which are packed together on chromosome 6. |
| Many COVID-19 patients produce immune responses against their body's tissues or organs Posted: 03 Jun 2021 05:10 PM PDT A new study has found that many patients with COVID-19 produce immune responses against their body's own tissues or organs. |
| Neurological symptoms like fatigue common in mild COVID, review finds Posted: 03 Jun 2021 05:10 PM PDT Neurological and psychiatric symptoms such as fatigue and depression are common among people with COVID-19 and may be just as likely in people with mild cases, according to a new review. |
| Posted: 03 Jun 2021 02:13 PM PDT A nasal therapy, built upon on the application of a new engineered IgM antibody therapy for COVID-19, was more effective than commonly used IgG antibodies at neutralizing the COVID-19 virus in animal models, according to new research. |
| Obesity may increase risk of long-term complications of COVID-19, study shows Posted: 03 Jun 2021 02:12 PM PDT A new study shows that survivors of COVID-19 who have moderate or severe obesity may have a greater risk of experiencing long-term consequences of the disease, compared with patients who do not have obesity. |
| COVID's impact on pregnancy, birth trends Posted: 03 Jun 2021 02:12 PM PDT The COVID-19 shutdown initially seemed to hit pause on pregnancy and birth rates, new research from one major hospital system suggests, but that trend is quickly reversing. |
| New method accurately reflects hotspots in epidemic Posted: 03 Jun 2021 02:12 PM PDT A new method to monitor epidemics like COVID-19 gives an accurate real-time estimate of the growth rate of an epidemic by carefully evaluating the relationship between the amount of viruses in infected people's bodies, called the viral load, and how fast the number of cases is increasing or decreasing. |
| No evidence that the shift to farming made males and females more physically similar Posted: 03 Jun 2021 02:11 PM PDT Scientists have proposed that males and females started to become more similar in size and shape after the origin of farming due to natural selection. However, a new evolutionary and genomic analysis finds no evidence that this occurred. |
| Extensive study identifies over a dozen existing drugs as potential COVID-19 therapies Posted: 03 Jun 2021 05:35 AM PDT Mining the world's most comprehensive drug repurposing collection for COVID-19 therapies, scientists have identified 90 existing drugs or drug candidates with antiviral activity against the coronavirus that's driving the ongoing global pandemic. |
| Autism: Study looks at ability to identify anger in facial expressions Posted: 02 Jun 2021 10:03 AM PDT The ability of people with autism to accurately identify facial expressions is affected by the speed at which the expression is produced and its intensity, according to new research. |
| Metal ions help COVID-19 virus disguise itself Posted: 02 Jun 2021 10:03 AM PDT Researchers are reporting a mechanism by which the COVID-19 virus takes advantage of changes in metal ion concentrations to disguise itself. |
| Less aviation during the global lockdown had a positive impact on the climate, study finds Posted: 02 Jun 2021 10:03 AM PDT High levels of aviation drive global warming, not only through greenhouse gas emissions, but also through additional clouds, researchers conclude in a new study. |
| Converting scar tissue to heart muscle after a heart attack Posted: 02 Jun 2021 07:16 AM PDT Researchers have shown that cardiac scar tissue (fibroblasts) can be directly reprogrammed to heart muscle cells (cardiomyocytes) in mice. By treating mice post-heart attack with a virus carrying cardiac transcription factors, they found that new cardiomyocytes were formed by fibroblasts converting into cardiomyocytes as opposed to fibroblasts fusing with existing cardiomyocytes. This study demonstrates the potential of direct reprograming as a strategy for cardiac regeneration after myocardial infarction. |
