Quantum entanglement is a state where electrons are spatially separated, but able to affect one another. It’s been proposed that birds’ eyes contain entanglement-based compasses. Conclusive proof doesn’t yet exist, but multiple lines of evidence suggest it.

Photograph of the quantum machine developed by O'Connell. The mechanical resonator is located to the lower left of the coupling capacitor (small white square). The qubit is connected to upper right of the coupling capacitor. A quantum machine is a human-made device whose collective motion follows the laws of quantum mechanics .
The first rapid growth spurt of the universe's most massive black holes occurred much earlier than astronomers previously thought, and are still growing fast, a new study finds. A team of astronomers from Tel Aviv University in Israel determined that the first period of fast growth of the most massive black holes occurred when the universe was only about 1.2 billion years old ? not 2 to 4 billion years old, as had been thought. Astronomers estimate the universe is about 13.7 billion years old. In the study, astronomers also determined that the universe's oldest and most massive black holes are also growing at a very fast rate. The findings will be detailed in an upcoming issue of the Astrophysical Journal.
There are a lot of questions in science that seem simple, but in fact lead to profound concepts.
By Daily Mail Reporter UPDATED: 20:10 GMT, 17 November 2010 It may look like any average building but behind closed doors could lie the answer to safe renewable energy of the future. Here at the National Ignition Facility in Livermore California, scientists are aiming to build the world's first sustainable fusion reactor by 'creating a miniature star on Earth'. Following a series of key experiments over the last few weeks, the £2.2 billion project has inched a little closer to its goal of igniting a workable fusion reaction by 2012. Experiment: Scientists hope that their £2.2billion 'miniature star on earth' will become the world's first sustainable fusion reactor by 2012 According to the National Ignition Facility (NIF) team in Livermore, on November 2 they fired up the 192 lasers beams at the centre of the reactor and aimed them at a glass target containing tritium and deuterium gas.
