Chirality yields colossal photocurrent
The Weyl semimetal Tantalum Arsenide has a colossal bulk photovoltaic effect – an intrinsic, or non-linear, generation of current from light more than ten times larger than ever previously achieved, according to researchers from Boston College, the University of California Los Angeles, and Ecole Polytechnique Federale de Lausanne.

Universe Preceded by an Antiuniverse?
A new cosmology model suggests that our Universe has a mirror image in the form of an “antiuniverse” that existed before the big bang, see Synopsis here.
AG Draconis, a mystery older than the Republic
Interacting variable stars, to which symbiotic binary stars belong, are among the most exciting objects that a variety of variable stars offer. Physical mechanisms related to transfer and accretion of matter cause observable activity by manifesting increases of brightness (about 2 – 5 mag) and significant changes in the spectra of these objects. The brightenings of symbiotic systems have been recorded since the early 20th…
