| SARS-CoV-2 research: Second possible effective mechanism of remdesivir discovered Posted: 10 May 2021 08:35 AM PDT After infection, SARS-CoV-2 causes the host cell to produce new virus particles and suppresses host cell defence mechanisms. Virus protein nsP3 plays a central role in the latter process. Using structural analyses, researchers have now discovered that a decomposition product of the remdesivir binds to nsP3. This previously unknown effective mechanism may be important for the development of new drugs to combat RNA viruses. |
| Microneedle patch delivers antibiotics locally in the skin Posted: 10 May 2021 08:35 AM PDT MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers are developing a microneedle patch that delivers antibiotics directly into the affected skin area. New results show that the microneedle patch effectively reduces MRSA bacteria in the skin. |
| How Legionella makes itself at home Posted: 10 May 2021 08:35 AM PDT Scientists have discovered a key protein that helps the bacteria that causes Legionnaires' disease to set up house in the cells of humans and other hosts. The findings could offer insights into how other bacteria are able to survive inside cells, knowledge that could lead to new treatments for a wide variety of infections. |
| Posted: 10 May 2021 07:44 AM PDT The process of combining maternal and paternal genetic information is surprisingly error-prone. |
| Prenatal exposure to famine heightens risk for later being overweight Posted: 10 May 2021 07:44 AM PDT An analysis of historical medical records found that men who were prenatally exposed during early gestation to the Dutch famine of 1944-1945 were 30 percent more likely to be overweight with a Body Mass Index of 25 or over at age 19, compared to a similar group not exposed to the famine. |

The finding suggests that tailored drug therapy can be designed and developed to reactivate and normalize cognitive function, say neuroscientists. |
| Meaningful movies help people cope with life's difficulties Posted: 10 May 2021 07:43 AM PDT Watching meaningful films - those that we find moving and poignant - can make us feel more prepared to deal with life's challenges and want to be a better person, a new study found. The findings point to one reason why people may choose to see movies that make them sad as well as happy and that may explore difficult subjects that aren't always uplifting. |
| Rapid lifestyle changes during early COVID-19 pandemic had no impact on climate change, study finds Posted: 10 May 2021 07:43 AM PDT Despite the rapid and significant changes in consumption patterns witnessed during the initial months of the COVID-19 pandemic, Japanese households maintained their normal levels of greenhouse gases emissions. The 'anthropause' -- reduction of human activity due to the pandemic -- made headlines last summer, but factory shutdowns and broken global supply chains did not translate into the adoption of eco-friendly lifestyles for the average household. |
| Reaching your life goals as a single-celled organism Posted: 10 May 2021 07:43 AM PDT How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails. A research team has now been able to simulate this process on the computer. |
| TB immune response discovery could significantly reduce disease harm Posted: 10 May 2021 07:43 AM PDT A pioneering study has discovered the presence of a harmful inflammatory protein in patients with symptomatic tuberculosis (TB). Researchers say, by targeting the IL-17 cytokine, a component produced naturally by the immune system in response to infection, excessive and damaging lung inflammation caused by TB may be significantly reduced to help speed up patient recovery. |
| Undetected early heart damage raises risk of death in hospitalized COVID-19 patients Posted: 10 May 2021 05:58 AM PDT First-phase ejection fraction, a possible indicator of heart failure, is a strong predictor of survival in hospitalized COVID-19 patients, according to a new study. Hospitalized patients who had impaired first-phase ejection fraction were nearly 5 times more likely to die from COVID-19 compared to patients with normal first-phase ejection fraction. |
| Managing children's weight, blood pressure and cholesterol protects brain function mid-life Posted: 10 May 2021 05:58 AM PDT Having high blood pressure, high cholesterol and/or obesity from childhood through middle age were linked to poorer brain function by middle age. These cardiovascular risk factors were linked with low memory, learning, visual processing, attention span, and reaction and movement time. Strategies to prevent heart disease and stroke should begin in childhood to promote better brain health by middle age. |
| Small study shows heart damage after COVID-19 uncommon in college athletes Posted: 10 May 2021 05:58 AM PDT In a small study, 82 percent of the college athletes with COVID-19 had symptoms, of which the majority were mild and did not require treatment. Further screening via cardiac MRI of the 4 percent of athletes identified with heart abnormalities found no heart damage or inflammation. All athletes resumed regular training and competition without difficulty after recovering from COVID-19. |
| Serotonin transporters increase when depression fades Posted: 10 May 2021 05:58 AM PDT Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells. A brain imaging study now shows that the average level of the serotonin transporter increased in a group of 17 individuals who recovered from depression after cognitive behavioral therapy. |
| Research results challenge a decades-old mechanism of how we hear sounds Posted: 10 May 2021 05:58 AM PDT Researchers have made several discoveries on the functioning mechanisms of the inner hair cells of the ear, which convert sounds into nerve signals that are processed in the brain. The results challenge the current picture of the anatomical organization and workings of the hearing organ, which has prevailed for decades. |
