I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Cell ‘membrane on a chip’ could speed up screening of drug candidates for COVID-19” Researchers have developed a human cell ‘membrane on a chip’ that allows continuous monitoring of how drugs and infectious agents interact with our cells, and may soon be used to test potential drug candidates for COVID-19.

“#Charcoal a weapon to fight superoxide-induced disease, injury” Artificial enzymes made of treated charcoal, seen in this atomic force microscope image, could have the power to curtail damaging levels of superoxides, toxic radical oxygen ions that appear at high concentrations after an injury.

“#Face coverings made from layered cotton fabric likely slow the spread of COVID-19 better than synthetics” The researchers looked at the yarn count, weave and mass of fabric samples such as this 100% cotton flannel (magnified about 220x times) — which was among the highest performers in their testing — in an attempt to determine how…
“#New ‘hybrid engine’ for biodegradable nanomotors that transport drugs to diseased tissue” Credit: Eindhoven University of Technology Nanomotors are molecular or nanoscale devices that can move through a biological medium by converting chemical energy into motion, and can be used for the delivery of pharmaceutical drugs to specific parts of the body. Typically, nanomotors use…
“#An analysis of the system-wide costs and benefits of using engineered nanomaterials on crop-based agriculture” Credit: CC0 Public Domain A team of researchers affiliated with several institutions in the U.S. has conducted an analysis of the system-wide costs and benefits of using engineered nanomaterials (ENMs) on crop-based agriculture. In their paper published in the journal…

“#Research in land plants shows nanoplastics accumulating in tissues” A graphic showing roots and root hairs absorbing nanoplastics. At the bottom are pieces of plastic waste. Credit: UMass Amherst/Xing labShandong University/Yuan and Wang labs As concern grows among environmentalists and consumers about micro- and nanoplastics in the oceans and in seafood, they are increasingly studied…
“#New nanoparticle drug combination for atherosclerosis developed” Antiatherogenic effect of CSNP. Credit: The Korea Advanced Institute of Science and Technology (KAIST) Physicochemical cargo-switching nanoparticles (CSNP) designed by KAIST can help significantly reduce cholesterol and macrophage foam cells in arteries, which are the two main triggers for atherosclerotic plaque and inflammation. The CSNP-based combination drug delivery…
“#Nanosponges could intercept SARS-CoV-2 coronavirus infection” In lab experiments, both the lung cell and immune cell types of nanosponges caused the SARS-CoV-2 virus to lose nearly 90% of its “viral infectivity” in a dose-dependent manner. Viral infectivity is a measure of the ability of the virus to enter the host cell and exploit its resources…
