  • Stressed-out worms hit the snooze button
    on December 14, 2017 at 7:19 pm

    When you catch a nasty cold, curling up in bed to sleep may be the only activity you can manage. Sleeping in response to stress isn't a uniquely human behavior: many other animals have the same reaction, and it's not clear why. While the circadian sleep that follows the pattern of the clock has been studied extensively, sleep that's triggered by stress is far less understood. […]

  • DNA: Supercoiling pushes molecular handcuffs along chromatin fibres
    on December 14, 2017 at 3:13 pm

    As it squeezes down the chromatin fiber, the cohesin protein complex extrudes a growing loop of DNA -- a bit like the quick-lacing system of trail-running shoes. But what is powering the movement of the protein? A team of scientists has found that the driving force could be the supercoiling of upstream DNA. Their research is thereby adding a key piece to the puzzle of gene expression regulation. […]

  • Scientists develop new, rapid pipeline for antimicrobials
    on December 14, 2017 at 2:23 pm

    Antibodies are proteins produced by the human immune system to ward off foreign invaders. Our bodies mount this defense rapidly, especially if they have seen the invader before, producing the needed antibody within days of infection. But to make them in the lab, antibodies specific for just one invader can take months, and be an expensive proposition. New research looks at mimicking nature's approach while dramatically reducing the antimicrobial discovery and production time. […]

  • Synthetic protein packages its own genetic material and evolves
    on December 14, 2017 at 2:23 pm

    Scientists have created computationally designed protein assemblies, that display some functions normally associated with living things, in the search for ways to transport therapeutic cargo into specific types of cells without using viruses as vehicles. These encapsulate their own RNA genomes and evolve new traits in complex environments. They are synthetic versions of the protein shells that viruses use to protect and deliver materials. The synthetic proteins evolved better RNA packaging, resistance against degrading enzymes in blood and longer circulation time. […]

  • Efforts of bacteria to defend against predators is so great that few resources left for offspring
    on December 13, 2017 at 3:47 pm

    Even bacteria have enemies -- in water, for example, single-celled ciliates preferably feed on microbes. The microbes protect themselves against predators by employing a variety of tricks, which the ciliates, in turn, attempt to overcome. There ensues an evolutionary competition for the best attack and defense mechanisms. […]

  • UVB radiation influences behavior of sticklebacks
    on December 13, 2017 at 3:46 pm

    Fish cannot see ultraviolet B rays but still change their behavior when they grow up under increased UVB intensity. According to studies by biologists, on three-spined sticklebacks (Gasterosteus aculeatus) increased UVB leads to a smaller body size and more risk-seeking behavior when faced with predators. Climate change is likely to increase UVB intensity, possibly with consequences for ecosystems and fish farming. […]
