  • Gli Animali (o Metazoi) sono  organismi eucarioti, eterotrofii, pluricellulari  e mobili durante almeno uno stadio della loro vita. Si riconoscono circa 1,5 milioni di specie note viventi.
  • Il loro processo evolutivo è in atto da oltre 500 milioni di anni.
  • Sono classificati in base ai differenti piani strutturali corporei che li caratterizzano.

  • Engineered proteins stick like glue -- even in water
    Researchers have found new adhesives based on mussel proteins could be useful for naval or medical applications. To create their new waterproof adhesives, researchers engineered bacteria to produce a hybrid material that incorporates naturally sticky mussel proteins as well as a bacterial protein found in biofilms -- slimy layers formed by bacteria growing o […]
  • Battling superbugs: Two new technologies could enable novel strategies for combating drug-resistant bacteria
    Two new technologies could enable novel strategies for combating drug-resistant bacteria, scientists report. Most antibiotics work by interfering with crucial functions such as cell division or protein synthesis. However, some bacteria have evolved to become virtually untreatable with existing drugs. In the new study, researchers target specific genes that a […]
  • Program predicts placement of chemical tags that control gene activity
    Biochemists have developed a program that predicts the placement of chemical marks that control the activity of genes based on sequences of DNA. By comparing sequences with and without epigenomic modification, they identified DNA motifs associated with the changes. They call this novel analysis pipeline Epigram and have made both the program and the DNA moti […]
  • Uncovering the forbidden side of molecules: Infrared spectrum of charged molecule seen for first time
    Researchers have succeeded in observing the “forbidden” infrared spectrum of a charged molecule for the first time. These extremely weak spectra offer perspectives for extremely precise measurements of molecular properties and may also contribute to the development of molecular clocks and quantum technology.
  • On/off switch for aging cells discovered by scientists
    An on-and-off “switch” has been discovered in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. In our bodies, newly divided cells constantly. However, most human cells cannot divide indefinitely -– with each division, a […]
