In the ranking of Science also studies dinosaurs and bacteria. With the studies on metamaterials, soon will be reality the mantle invisibility. Today a single computer rattles off the DNA of three individuals in a week
In ten years we have learned to see better. Our eyes are placed on individual neurons that "light up" in the brain, have spied la vita interiore della cellula e seguito in diretta lo sviluppo di un embrione. Hanno raggiunto pianeti simili alla Terra, annusato l'acqua su Marte e "fotografato" l'universo bambino nei primi istanti dopo il Big Bang.
È ricco di figurine, l'album delle scoperte del decennio della rivista Science. Come quella della livrea colorata di alcuni dinosauri del Giurassico, frutto della scoperta che il Dna può conservare dopo decine di migliaia di anni le sue informazioni e far rivivere di fronte ai nostri occhi il volto di un uomo di Neanderthal di 40mila anni fa (pelle chiara e i fulvi) o il sangue di un mammuth, che conteneva un antigelo per sopravvivere agli inverni.
Dal freddo al caldo, Gallery discoveries remind us that a decade ago did not speak of global warming if not in a very skeptical. Today, the magazine writes, "warming is unequivocal, that is caused by man is very plausible and equally unlikely is the ability of nature to restore the balance themselves."
On the other hand, the horizon of our eyes widened. And he wrote that 410 years ago helped to send Giordano Bruno burned at the stake ("There are countless suns and countless earths that revolve around their own") is now more of a certainty is an iPhone app that lets you follow the discovery of new potentially habitable exoplanets. Currently more than 500.
similar to the discovery that the Sun is revolving around the Earth - according to Science - the observation that only one cell in the human body out of ten belong to us. These and many are bacteria that live peacefully on our body if we think in terms of numbers would have a clear majority. count was a task made possible thanks to the rapid sequencing of DNA has achieved. Ten years ago the first reading of the human genome was announced with great fanfare, after a decade of work by hundreds of scientists and the same computer. Today a single computer rattles off the DNA of three individuals in a week.
In the ranking of 2010, winning is the "quantum machine" of researchers from the University of California. For the first time, says Science, "an object built by a man does not move according to the laws of classical mechanics, but according to quantum mechanics," in which atoms and particles are never still, and can be in two places at once.
Over the past decade we have learned to see better, but maybe in the next we will not see anything. If you will succeed studies of metamaterials that deflect light, scientists amaze us with his cloak of invisibility. His early pieces are taking shape in the laboratory. See you next decade may not be the best hope.
