  1. A new methodology quickly reveals metabolic fluxes in cells

    02.24 / 10:58 phys.org Phys.org -Science news
    Although photographs of the underground stations in Barcelona would reveal the number of people waiting, when rush hour takes place, and offer clues about why some stations are busier than others, they can't reveal whether something has happened between two stations that has caused disruptions. Biologists studying cells confront a similar…
  2. Atom-scale oxidation mechanism of nanoparticles helps develop anti-corrosion materials

    02.24 / 10:58 phys.org Phys.org -Science news
    The research group led by Prof. BAO Xinhe from Dalian Institute of Chemical Physics, Chinese Academy of Sciences, has discovered that oxide nanostructures (NSs) with a diameter below 3 nm could exhibit superior oxidation resistance to larger NSs. By investigating the oxidation mechanism at the atomic level, the team has proposed, for the first time, a "dynamic size effect" that determines the stability of supported…

  10. Agricultural robot may be 'game changer' for crop growers, breeders

    02.23 / 22:52 phys.org Phys.org -Science news
    A semiautonomous robot may soon be roaming agricultural fields gathering and transmitting real-time data about the growth and development of crops, information that crop breeders—and eventually farmers—can use to identify the genetic traits in plants likely to produce the greatest yie…
  11. New gene for atrazine resistance identified in waterhemp

    02.23 / 22:52 phys.org Phys.org -Science news
    Waterhemp has been locked in an arms race with farmers for decades. Nearly every time farmers attack the weed with a new herbicide, waterhemp becomes resistant to it, reducing or eliminating the efficacy of the chemical. Some waterhemp populations have evolved resistance to multiple herbicides, making them incredibly difficult to…
  12. Researchers find new clues for nuclear waste cleanup

  13. NIST patents first DNA method to authenticate mouse cell lines

    02.23 / 22:52 phys.org Phys.org -Science news
    "A case of mistaken identity" may drive the plot of the latest spy film or crime novel, but it's only a tale of trouble for geneticists, oncologists, drug manufacturers and others working with mouse cell lines, one of the most commonly used laboratory model systems for genetic research. Cell lines that have been contaminated or misidentified due to poor laboratory technique and human error lead to inaccurate research studies, retracted publications and wasted resources. In fact, many…

  15. Chu's Limit—a limit no more

    02.23 / 19:38 phys.org Phys.org -Science news
    Chu's Limit, a fundamental principle of electromagnetics, dictates that the bandwidth an antenna can function in has a maximum level proportional to the physical size of the antenna—the smaller the antenna, the smaller the bandwidth, the slower and less capable the communications link. Chu's Limit has been a foundational law of antenna and telecommunications research since its introduction in the late 1940s, but a scientist at the Space and Naval Warfare Systems Center Pacific (SSC P…
