European robins may maintain quantum entanglement in their eyes a full 20 microseconds longer than the best laboratory systems, say physicists investigating how birds may use quantum effects to “see” Earth’s magnetic field.
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. Findings like this one underscore just how sophisticated those compasses may be. “How can a living system have evolved to protect a quantum state as well — no, better — than we can do in the lab with these exotic molecules?”
Asked quantum physicist Simon Benjamin of Oxford University and the National University of Singapore, a co-author of the new study. “That really is an amazing thing.” Research since then has revealed the existence of special optical cells containing a protein called cryptochrome.

For interpolation, I use the quadratic B-spline presented here: Analysis and Reduction of Quadrature Errors in the Material Point Method. Instead of integrating the density over time (which is what most of the MPM papers do), I do a density summation every frame. Material Parameters Some of these parameters are hard to explain in one or two sentences (and a couple I made up) so I'll also link you to their corresponding Wikipedia pages.

The qubit is connected to upper right of the coupling capacitor. The first quantum machine[edit] Cooling to the ground state[edit] In order to demonstrate the quantum mechanical behaviour, the team first needed to cool the mechanical resonator until it was in its quantum ground state (the state with the lowest possible energy). Controlling the quantum state[edit] In quantum mechanics, vibrations are made up of elementary vibrations called phonons.

Universe's Most Massive Black Holes Got Huge Early. 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. [Photos: Black Holes of the Universe] Black hole giants Most galaxies in the universe, including our own Milky Way, harbor supermassive black holes at their center. How heavyweight black holes get big The team found that the very first black holes ? Large Hadron Collider - How does it work? Don’t cross the LHC stream! There are a lot of questions in science that seem simple, but in fact lead to profound concepts.
Why is the sky dark at night? Why does gravity pull me down? Why is the Sun hot? And some questions seem silly and frivolous, but it turns out are really hard to answer, and in fact scientists might disagree on the answer. Case in point: what happens if you put your hand in the beam of the Large Hadron Collider? So the folks at Sixty Symbols asked this of several scientists, and the first four minutes of this video are the result: Fantastic! It’s complicated! And there’s more. So taken in total, I’m not sure what would happen.
Bang! But depositing all that energy all at once may not be possible; protons are so small they may not all hit you and suddenly stop. The point? So I propose that in a few decades, when funding is running low and the LHC’s primary objectives are met, we test this idea out. Tip o’ the lead shielding to AstroPixie.

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. For a direct comparison, the temperature at the centre of the sun is 27 million degrees Fahrenheit.
