CLEVELAND, Aug. 24, 2020 — An effort led by Federico Capasso of Harvard University and Giuseppe Strangi of Case Western Reserve University is using liquid crystals to improve the reconfigurability of metalenses. This advancement brings the viability of metalenses for commercial use closer to reality.
The researchers harnessed nanoscale forces to infiltrate liquid crystals between the microscopic pillars that allow metalenses to focus light. This allowed them to shape and diffract light in new ways, “tuning” the focus power, Strangi said.

For example, many proteins and cell membranes are liquid crystals. Other well-known examples of liquid crystals are solutions of soap and various related detergents, as well as the tobacco mosaic virus, and some clays.

As these cells grew and reached maturity, investigators exposed the retinal organoids to the SARS-CoV-2 virus. To their surprise, Menuchin-Lasowski et al. found that SARS-CoV-2 not only infected cells but also replicated. This was evident by the production of viral plaques in the cells that were exposed to the virus. The amount of viral plaque significantly increased within the first 24 hours and nearly doubled after another 24 hours. Interestingly, after 72 hours, the amount of plaque decreased back to the levels detected during the first 24 hour time point. Previous studies have observed a similar pattern of Covid-19 infection in human brain organoids.

The first thing to understand is that coronavirus can spread through the eyes — just as it does through the mouth or nose.
When someone who has coronavirus coughs or talks, virus particles can spray from their mouth or nose into your face. You are likely to breathe these tiny droplets in through your mouth or nose. But the droplets can also enter your body through your eyes.
People who have coronavirus can also spread the disease through their tears. Touching tears or a surface where tears have landed is another way someone can become infected.
