Molti geni codificano per proteine enzimatiche attive per una reazione biochimica in una delle vie metaboliche dell’organismo.

Se uno di questi geni muta, il nuovo codice contiene l’informazione per produrre un enzima difettoso, incapace di portare avanti la sua reazione metabolica determinando un blocco della via metabolica nella quale è coinvolto.

  • Smarter than a first-grader? Crows can perform as well as 7- to 10-year-olds on cause-and-effect water displacement tasks
    In Aesop's fable about the crow and the pitcher, a thirsty bird happens upon a vessel of water, but when he tries to drink from it, he finds the water level out of his reach. Not strong enough to knock over the pitcher, the bird drops pebbles into it -- one at a time -- until the water level rises enough for him to drink his fill. New research demonstra […]
  • Vasculature of the hive: How honey bees stay cool
    Honey bees, especially the young, are highly sensitive to temperature and to protect developing bees, adults work together to maintain temperatures within a narrow range. New research also supports the theoretical construct of the bee hive as a superorganism — an entity in which its many members carry out specialized and vital functions to keep the whole fun […]
  • Spinach could lead to alternative energy more powerful than Popeye
    Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Physicists are using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun's energy into carbohydrates used to power ce […]
  • Bird 'backpacks' put wood thrush migration on the map
    Researchers have created the first migratory connectivity map produced for a songbird, using tracking from both breeding and winter sites. They were able to trace the route taken by wood thrushes from North America using bird 'backpacks'. They discovered that wood thrushes from Canada don't migrate to the same areas as their southern neighbors […]
  • 15-year analysis of blue whale range off California finds conflict with shipping lanes
    A comprehensive analysis of the movements of blue whales off the West Coast found that their favored feeding areas are bisected by heavily used shipping lanes, increasing the threat of injury and mortality. But moving the shipping lanes off Los Angeles and San Francisco to slightly different areas -- at least, during summer and fall when blue whales are most […]
