Panda gigante, Ailuropoda melanoleuca, David 1869



Il panda gigante  non è più in imminente via di estinzione. L’orso-simbolo della Cina, emblema della lotta per la salvaguardia della natura, nel 2010 ha invertito la tendenza negativa tra nascite e decessi.

A family of Ground Squirrels The ground squirrels are members of the squirrel family of rodents (the Sciuridae) which generally live on or in the ground, rather than trees. The term is most often used for the medium-sized ground squirrels, as the larger oSMS_20140626_0142.jpgSMS_20140626_0146.jpgCat Lovers

  • Mutations from Venus, mutations from Mars: Genetics, Men and fertility problems
    Researchers explain why genetic fertility problems can persist in a population. Some 15% of adults suffer from fertility problems, many of these due to genetic factors. This is something of a paradox: We might expect such genes, which reduce an individual's ability to reproduce, to disappear from the population. Research may now have solved this riddle. […]
  • Interfering with interferon
    Using the body's natural virus killers to prevent and treat HIV infection has been problematic until now because of the strong inflammatory response these molecules can arouse as they get rid of the invaders. Now, research has demonstrated how suppressing the activity of these molecules -- interferons -- around the time of infection could have long-term […]
  • New species of mayfly discovered in India
    Scientists have discovered a new species of mayfly in the southern Western Ghats, a mountain range along the west coast of India. The larvae have light-brown heads with light-yellow antennae, and they grow to be about 4-5 millimeters in length. Adults are also about five millimeters long, and the males and females both lack hind wings.
  • Dinosaurs fell victim to perfect storm of events, study shows
    Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say. They found that in the few million years before a 10km-wide asteroid struck what is now Mexico, Earth was experiencing environmental upheaval. This included extensive volcanic activity, changing sea levels and vary […]
  • New, noncommittal mechanism of drug resistance discovered
    Microorganisms like bacteria and fungi can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs. These permanent mutations were once thought to be the only way for drug resistant strains to evolve. Now a new study has shown that microorganisms can use a temporary silencing of drug targets -- known as epimutations -- […]
