Drones able to take water samples could be the first in a new wave of hands-on aerial robots.

El movimiento brusco de las placas tectónicas provoca terremotos, que desembocan en desastres naturales y cuantiosas pérdidas materiales y humanas. Normalmente se deslizan suavemente durante cientos de millones de años, pero se ignoraba por qué en ocasiones crujen abruptamente. Ahora, parece que este enigma de la geología ha encontrado respuesta.

Earth’s water has a mysterious past stretching back to the primordial clouds of gas that birthed the Sun and other stars. By using telescopes and computer simulations to study such star nurseries, researchers can better understand the cosmic chemistry that has influenced the distribution of water in star systems across the Universe.

Natural selection has shaped many different animal groups, from V-like formations of bird flocks to circular mills of schooling fish. These shapes are the result of millions of years of evolution. Animals that hold their formation survive and those that don’t follow the group die out, either left behind or picked off by predators.

Critics of genetic engineering have long worried about the risk of modified organisms escaping into the environment. A biological-containment strategy described this week in Nature has the potential to put some of those fears to rest and to pave the way for greater use of engineered organisms in areas such as agriculture, medicine and environmental clean-up.

There are hundreds, thousands, probably hundreds of thousands of people around the world who have gone through their own version of hell—some of them resilient, some not. But in this room of psychologists and neuroscientists, Lindhout was a warm-blooded reminder why the work they do matters.

Durante años, los médicos le dijeron a Milena Channing que había quedado completamente ciega después de un infarto cerebral. Pero un día empezó a ver algo muy concreto. Algo que según los doctores no era posible.
