Newsflash: Time May Not Exist.
Time, in this view, is not something that exists apart from the universe. There is no clock ticking outside the cosmos. Most of us tend to think of time the way Newton did: “Absolute, true and mathematical time, of itself, and from its own nature, flows equably, without regard to anything external.” But as Einstein proved, time is part of the fabric of the universe. Contrary to what Newton believed, our ordinary clocks don’t measure something that’s independent of the universe. In fact, says Lloyd, clocks don’t really measure time at all. “I recently went to the National Institute of Standards and Technology in Boulder,” says Lloyd. Rovelli, the advocate of a timeless universe, says the NIST timekeepers have it right. “What happens with the Wheeler-DeWitt equation is that we have to stop playing this game. The problem, in brief, is that time may not exist at the most fundamental level of physical reality.
Einstein, for one, found solace in his revolutionary sense of time. Discover Magazine: The latest in science and technology news, blogs and articles. In New Quantum Experiment, Effect Happens Before Cause. A real-world demonstration of a thought experiment conducted at the University of Vienna, has produced a result that is somewhat befuddling to people with what the lead researcher calls a "naïve classical world view.
" Two pairs of particles are either quantum-entangled or not. One person makes the decision as to whether to entangle them or not, and another pair of people measure the particles to see whether they're entangled or not. The head-scratcher is: the measurement is made before the decision is made, and it is accurate.
"Classical correlations can be decided after they are measured," says Xiao-song Ma, the writer of the study. Entanglement can be created "after the entangled particles have been measured and may no longer exist. " The finding can be integrated into potential quantum computers, one hopes. Causality, clearly, is a quaint, irrelevant concept. [Nature] Human Biology. Evolution. Athene's Theory of Everything. A Brilliant List of Science Books for People Who Want Their Minds Blown.
Encyclopedia of Life. How to Picture a Black Hole | Wired Science. This month, researchers are inaugurating the Event Horizon Telescope, a project that will try to take the first detailed pictures of the supermassive black hole at the center of our galaxy.This observation would be a remarkable achievement, underscoring the progress that has been made in black-hole research in just the last few decades. As recently as the 1970s, astronomers still argued over whether black holes were theoretical constructs or real physical objects. They now have ample evidence that black holes are not only real, but abundant in the cosmos.Here on Earth, advanced computer simulations have given astronomers a wealth of information, leading theoretical physicist Kip Thorne of Caltech to suggest that black-hole research is entering a new golden age.

Kepler 22-b: Earth-like planet confirmed. 5 December 2011Last updated at 17:50 The planet, shown here in an artist's conception, circles its host star in 290 days Astronomers have confirmed the existence of a nearly Earth-sized planet in the "habitable zone" around a star not unlike our own. The planet, Kepler 22-b, lies about 600 light-years away and is about 2.4 times the size of Earth, and models suggest it has a temperature of about 22C. It is the closest confirmed planet yet to one like ours - an "Earth 2.0". However, the team does not yet know if Kepler 22-b is made mostly of rock, gas or liquid.
During the conference at which the result was announced, the Kepler team also said that it had spotted some 1,094 new candidate planets - nearly doubling the telescope's haul of potential far-flung worlds. Kepler 22-b was one of 54 exoplanet candidates in habitable zones reported by the Kepler team in February, and is just the first to be formally confirmed using other telescopes.

Right now, while you are reading this article, billions of your cells are busy replicating your DNA information.
Although molecules are smaller than the wavelength of light, and thus we have no way to directly observe them, can we still somehow visualize these processes? Biomedical animator and MacArthur Foundation nominee Drew Berry of the Walter and Eliza Hall Institute of Medical Research presents in a recent TEDx talk of less than 9 minutes, the state-of-the-art in molecular animation. He shows an accurate representation of the actual biological processes that happen on molecular scale, even at the correct speed2. Next to a movie that originates back from around 2003 that focuses on the replication of DNA, he also shows a newer version that has been accomplished through "updated science, updated technology", revealing how DNA mitosis through a nifty process of some quite 'mechanical' signal broadcasting system.
Shape-Shifting: Researchers Change How Monkeys See in 3-D. At the backs of your eyeballs, on the living projector screens called retinas, your corneas display upside-down 2-D images of the world around you. With some complex mental origami, your brain transforms those flat worlds into a beautiful 3-D model of everything you see. In a new study, researchers changed how monkeys perceived 3-D optical illusions by stimulating particular clusters of neurons in their brains.
The researchers think the region they tweaked is where 3-D modeling happens. Peter Janssen of Katholieke Universiteit Leuven in Belgium and his colleagues trained two rhesus macaques to recognize 3-D shapes created by an arrangement of dots on a computer screen—somewhat like the illusions in the popular Magic Eye book series, except that the monkeys wore goggles called stereoscopes to make the images pop. First, Janssen trained the monkeys to move their eyes to the left when they saw a concave image and to the right when they saw a convex image. The Arrow of Time feat. Sean Carroll.
