Low-level jets create winds of change for turbines
Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. In the Journal of Renewable and Sustainable Energy, researchers considered three different scenarios in which the LLJs were above, below, and in the middle of the turbine rotors. (2021-02-23)

Super-Earth atmospheres probed at Sandia's Z machine
Sandia National Laboratorie' Z machine has replicated the gravitational pressures on so-called ''super-Earths'' to determine which might maintain atmospheres that could support life. Astronomers believe that super-Earths -- collections of rocks up to eight times larger than Earth -- exist in the millions in our galaxy. ''The question before us is whether any of these super planets are actually Earthlike, with active geological processes, atmospheres and magnetic fields,'' said Sandia physicist Joshua Townsend. The researchers found seven. (2021-02-09)

Discoveries at the edge of the periodic table: first ever measurements of einsteinium
Since element 99 - einsteinium - was discovered in 1952 at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is exceptionally radioactive. A team of Berkeley Lab chemists has overcome these obstacles to report the first study characterizing some of its properties, opening the door to a better understanding of the remaining transuranic elements of the actinide series.

Nuclear physicist's voyage towards a mythical island
Theories were introduced as far back as the 1960s about the possible existence of superheavy elements. Their most long-lived atomic nuclei could give rise to a so-called ''island of stability'' far beyond the element uranium. However, a new study, led by nuclear physicists at Lund University, shows that a 50-year-old nuclear physics manifesto must now be revised. (2021-01-26)

Nuclear war could trigger big El Niño and decrease seafood
A nuclear war could trigger an unprecedented El Niño-like warming episode in the equatorial Pacific Ocean, slashing algal populations by 40 percent and likely lowering the fish catch, according to a Rutgers-led study. The research, published in the journal Communications Earth & Environment, shows that turning to the oceans for food if land-based farming fails after a nuclear war is unlikely to be a successful strategy - at least in the equatorial Pacific.
