Researchers in the Department of Plant Biology at Rutgers University took a closer look at the role of amino acids and nitrogen on cool-season turfgrass regrowth or recovery from drought stress.
A grid of quantum islands could reveal secrets for powerful technologies
Life is motion. And so, to understand how living organisms function, one must understand the movement and reorganization of the atoms and molecules that compose them. The approach called "molecular dynamics simulation" enables scientists to use computer programs to simulate the dynamic motion of all the atoms in a molecular system as a function of time.
Chemical defenses may not protect Antarctic seafloor animals, jeopardizing their value for drug discovery
Researchers at the National Institute of Standards and Technology (NIST) have created grids of tiny clumps of atoms known as quantum dots and studied what happens when electrons dive into these archipelagos of atomic islands. Measuring the behavior of electrons in these relatively simple setups promises deep insights into how electrons behave in complex real-world materials and could help...
Webb draws back curtain on universe's early galaxies
Long-lived sponges, intestine-like worms, colonies of sea squirts and many other cold-loving animals populate the seafloor around Antarctica. But the arrival of outsiders—borne in ships' ballast water, on plastic refuse or on floating kelp, or encouraged by warming temperature—threaten this menagerie.
Offshore wind farms may harm seabirds, but scientists see potential for net positive impact
A few days after officially starting science operations, the NASA/ESA/CSA James Webb Space Telescope propelled astronomers into a realm of early galaxies, previously hidden beyond the grasp of all other telescopes.
