Next step in simulating the universe
Researchers led by the University of Tsukuba developed a way to accurately represent the behavior of elementary particles called neutrinos in computer simulations of the Universe. The simulation results reveal the effects of neutrinos on the formation and growth of galaxies for different values of the uncertain neutrino mass. The work marks a milestone in simulating the Universe and could help determine the neutrino mass. (2020-12-01)

Molecular compass for cell orientation
Plants have veins that transport nutrients through their body. These veins are highly organized. The hormone auxin travels directionally from cell-to-cell and provides cells with positional information, coordinating them during vein formation and regeneration. Scientists at IST Austria now discovered how cells translate auxin signals into forming a complex system of veins. This phenomenon also applies to wound healing and might lead to more mechanically resistant plants and further agricultural implications. (2020-10-29)

Black hole 'family portrait' is most detailed to date
An international research collaboration including Northwestern University astronomers has produced the most detailed family portrait of black holes to date, offering new clues as to how black holes form. An intense analysis of the most recent gravitational-wave data available led to the rich portrait as well as multiple tests of Einstein's theory of general relativity. (The theory passed each test.) The observations could be a key piece in solving the many mysteries of exactly how binary stars interact. (2020-10-28)
