One of the many questions that scientists are interested in today is how long the virus leading to COVID-19 stays ‘alive’ in the environment after someone infected coughs or sneezes. When the droplets containing the virus evaporate, the virus also dies. Therefore, the likelihood of becoming infected with COVID-19 may directly depend on how long…
COVID-19 is most often transmitted through the air and during direct contact with an infected, and the likelihood of getting infected by touching objects is very low, experts from the Chinese Center for Disease Control and Prevention found out. According to The Daily Mail, infected people exhale millions of viral particles every hour, moreover, even…
Scientists from the Department of Chemical & Biological Engineering at the University of New Mexico (US) have developed synthetic red blood cells that ‘work’ no worse than real ones. Their work was published in the journal ACS Nano. Red blood cells are disc-shaped and deliver oxygen from the lungs to all organs and tissues of…
COVID-19 can damage the placenta, the American Journal of Clinical Pathology reported referring to a new study. Although the injuries found did not affect the health of the children, the authors warn that such injuries could potentially disrupt the course of pregnancy.

Stress can cause hair to gray, a new study claims. However, to this day, there has been very little real evidence to support the link between stress and graying.

Coronavirus attacks not only the lungs but also the heart. And it is precisely the negative effect produced on the heart that can determine the risk of death.

Scientists from the University Medical Center Hamburg-Eppendorf found particles of the SARS-CoV-2 virus in the kidneys, heart, liver, and brain of patients. This may explain the wide range of symptoms of COVID-19. As reported in a study, the SARS-CoV-2 coronavirus, once in the human body, attacks not only the lungs but also other organs. Microbiologists…
