Environmental impact assessment of plastic waste during the outbreak of COVID-19 and integrated strategies for its control and mitigation.

During the COVID-19 pandemic, many positive shifts have been observed in the ecosystem, with a significant decrease in the greenhouse gas emissions and air pollution. On the other hand, there were unavoidable negative shifts due to a surge in demand for plastic products such as food and groceries' delivery packaging, single-use plastics, medical and personal protective equipment to prevent transmission of COVID-19. Plastic pollution can be considered as a key environmental issue in world due to the huge footprints of plastics on natural ecosystems and public health.

Magneto-optical characteristics of human sperms: normal and deformed.

In this study we report on magnetic orientation of human sperms. Samples were taken from 17 donors. Normal human sperms became oriented with their long axis perpendicular to the magnetic field (1 T maximum).
