SOMMARIO
- 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.

- 'Whodunnit' of Irish potato famine solvedAn international team of scientists reveals that a unique strain of potato blight they call HERB-1 triggered the Irish potato famine of the mid-19th century. […]
- Resistance to last-line antibiotic makes bacteria resistant to immune systemBacteria resistant to the antibiotic colistin are also commonly resistant to antimicrobial substances made by the human body, according to a new study. Cross-resistance to colistin and host antimicrobials LL-37 and lysozyme, which help defend the body against bacterial attack, could mean that patients with life-threatening multi-drug resistant infections are […]
- New NOAA report examines national oil pollution threat from shipwrecksNOAA presented to the U.S. Coast Guard a new report that finds that 36 sunken vessels scattered across the U.S. seafloor could pose an oil pollution threat to the nation's coastal marine resources. Of those, 17 were recommended for further assessment and potential removal of both fuel oil and oil cargo. […]
- The mammoth's lament: How cosmic impact sparked devastating climate changeResearchers have found evidence of a major cosmic event near the end of the Ice Age. The ensuing climate change forced many species to adapt or die. […]
- Parasitic wasps use calcium pump to block fruit fly immunityParasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses. Researchers say their findings have uncovered an important component of cellular immunity, one that parasites have learned to take advantage of. […]
