Another Earth
Astrónomos europeos hallaron un planeta rocoso, como el nuestro que podría contener agua y vida a 22 años luz de la Tierra, en la constelación de Escorpio.

Get physical
"Have you noticed how physical has begun to be more popular as one element in retronyms relating to the online world? If you actually go into a store to buy something, instead of ordering online, that’s physical shopping. Similarly, a physical book is one made with ink on dead trees, in contrast to a digital e-book. Both terms have been around for more than a decade but my impression is that they’ve only recently gone mainstream."

Nano 'ears' for nano whispers
Alexander Ohlinger at Ludwig Maximilian University in Munich (LMU), Germany, and colleagues suspended gold nanoparticles in a drop of water. They trapped one sphere in a laser beam and then fired rapid pulses of light from a second laser at others a few micrometres away. The pulses heated the nanoparticles, which disturbed the water around them, generating pressure, or sound, waves."

Ohm's law at atomic scale
"A new technique for embedding atomic-scale wires within crystals of silicon has revealed that Ohm's law can hold true for wires just four atoms thick and one atom tall. The result comes as a surprise because conventional wisdom suggests that quantum effects should cause large deviations from Ohm's law for such tiny wires. Paradoxically, the researchers hope the finding will aid the development of quantum computers."
