Biomedical scientists invent shape-shifting nanomaterial with biogenic capabilities

The Journal of the American Chemical Society published a description of the nanomaterial which in sheet form is 10,000 times thinner than the width of a human hair, is made of synthetic collagen. Naturally, occurring collagen is the most abundant protein in humans, making the new material intrinsically biocompatible.

The development of the new shape-shifting nanomaterial at Emory was ‘a fortuitous accident’ according to the researchers.(Reuters file photo. Representative image)

Vitamin D inexpensive, low-risk, can strengthen immune response to COVID-19: Experts

Stressing that Vitamin D is inexpensive and has negligible risk when compared to the considerable risk of Covid-19, global researchers on the disease have asked governments to make it part of their strategy against the novel coronavirus.

There is no clinical evidence to prove low levels of Vitamin D lead to severe Covid-19 symptoms but there is a definite connect between the “sunshine vitamin” and immune responses to the disease, say experts as the pandemic spreads across the world and concerns mount over a new mutant strain.(Pixabay)
