  1. Long-term fate of tropical forests may not be as dire as believed, study says

    04.28 / 19:28 phys.org Phys.org -Science news
    Tropical rainforests are often described as the "lungs of the earth," able to inhale carbon dioxide from the atmosphere and exhale oxygen in return. The faster they grow, the more they mitigate climate change by absorbing…
  2. With unique data, researchers track the effect of Brazil's 'Soy Moratorium' on an advancing agricultural frontier

    04.28 / 19:28 phys.org Phys.org -Science news
    The Brazilian state of Mato Grosso produces enough soybeans to be the equivalent of Iowa and Illinois put together. But it also plays home to lush Amazon rain forest, one of the richest, and most vulnerable, ecological treasures on our…
  3. Hybrid circuits can increase computational power of chaos-based systems

    04.28 / 19:28 phys.org Phys.org -Science news
    New research from North Carolina State University has found that combining digital and analog components in nonlinear, chaos-based integrated circuits can improve their computational power by enabling processing of a larger number of inputs. This "best of both worlds" approach could lead to circuits that can perform more computations without increasing their physical…

  6. Discovery of a facile process for H2 production using ammonia as a carrier

    04.28 / 18:19 phys.org Phys.org -Science news
    Hydrogen (H2) has attracted considerable attention as a clean energy source because the only by-product of its reaction with oxygen is water, and high efficiency for energy conversion is achieved when it is combined with fuel cell…
  7. Trump moves to lift bans on Arctic drilling

    04.28 / 18:19 phys.org Phys.org -Science news
    US President Donald Trump signed an executive order aimed at lifting bans on drilling for oil and gas in offshore Arctic and Atlantic areas, saying it would pull in "billions of dollars" for America and create…
  8. Modern metabolic science yields better way to calculate indoor CO2

    The air we breathe out can help us improve the quality of the air we breathe…
  9. Plague bacteria take refuge in amoebae

    04.28 / 18:19 phys.org Phys.org -Science news
    Yersinia pestis, the bacterium that causes bubonic plague, can survive within the ubiquitous soil protozoan, the amoeba, by producing proteins that protect against the latter microbe's digestion. The research is published April 28th in Applied and Environmental Microbiology, a journal of the American Society for…
  10. Tiny joints for reconfigurable microstructures

    04.28 / 16:01 phys.org Phys.org -Science news
    Leiden physicists exploit self-assembly of small particles to someday create functional structures such as micro-robots from the bottom up. Now they took an important step forward by experimentally realizing joints on the micrometer scale. The study is published in Nanoscale…
  11. German airlines to scrap 'two-person' cockpit rule

    04.28 / 16:01 phys.org Phys.org -Science news
    German airlines will no longer require two people to be in the cockpit at all times, an industry group said Friday, abandoning a rule introduced after a deadly crash in…
  12. Scientists set record resolution for drawing at the one-nanometer length scale

    04.28 / 16:01 phys.org Phys.org -Science news
    The ability to pattern materials at ever-smaller sizes—using electron-beam lithography (EBL), in which an electron-sensitive material is exposed to a focused beam of electrons, as a primary method—is driving advances in nanotechnology. When the feature size of materials is reduced from the macroscale to the nanoscale, individual atoms and molecules can be manipulated to dramatically alter material properties, such as color, chemical reactivity, electrical conductivity, and light int…

  16. Further knowledge required about the differences between milk proteins

    04.28 / 14:53 phys.org Phys.org -Science news
    New knowledge on milk composition and quality is of essential importance to consumers as well as the industry. There are therefore considerable research efforts in milk worldwide. One of the major topics concerns milk's content of different proteins and their importance to human health. Basically, milk consists of two protein types - whey and casein. Casein can be further divided into four categories. One of these, beta casein, attracts particular attention. Several beta casein types exist…
