How will we achieve carbon-neutral flight in future?

The E.P.A. has finalized a so-called transparency plan that it says will improve the credibility of science. Scientists say it is designed to stop new public health protections by limiting what research the agency can consider.

When solar cells are exposed to sunlight, certain bound ‘charge pairs’ are generated in its components, which need to be separated for photocurrent generation. Ferroelectric materials, due to their spontaneous electric polarization, are highly efficient at charge separation but do poorly in light-to-electricity conversion. Now, scientists have demonstrated using theoretical calculations that antiperovskite oxides, a class of ferroelectric materials, show large absorption of sunlight, making them suitable photoabsorbers for thin film solar cells.

A four-year study concludes that the fungal disease, white-nose syndrome, poses a severe threat to many western North American bats.
