Physics
Physics (from ) is a natural science that involves the study of matter and its motion through spacetime, along with related concepts such as energy and force. [http://en.wikipedia.org/wiki/Physics]

The Large Hadron Collider (LHC), a 27 kilometer (17 mile) long particle accelerator straddling the border of Switzerland
and France, is nearly set to begin its first particle beam tests. The European Organization for Nuclear Research (CERN)
is preparing for its first small tests in early August, leading to a planned full-track test in September - and the first
planned particle collisions before the end of the year. The final step before starting is the chilling of the entire
collider to -271.25 C (-456.25 F). Here is a collection of photographs from CERN, showing various stages of completion
of the LHC and several of its larger experiments (some over seven stories tall), over the past several years. (27 photos total)

Mighty mice for sale -- mighty expensive at least A mouse with arthritis runs close to $200; two pairs of epileptic mice can cost 10 times that. You want three blind mice? That'll run you about $250. And for your own custom mouse, with the genetic modification of your choosing, expect to pay as much as $100,000. Read More Here
- Record Set for Hottest Temperature on Earth: 3.6 Billion Degrees in Lab Scientists have produced superheated gas exceeding temperatures of 2 billion degrees Kelvin, or 3.6 billion degrees Fahrenheit.This is hotter than the interior of our Sun, which is about 15 million degrees Kelvin, and also hotter than any previous temperature ever achieved on Earth, they say. They don't know how they did it.Read More Here

I reproduce the content of the articles here, since it is permit. Happy reading :-)
Here an example:
Quantum Nonlocality and Nonspatiality
In the early eighties physicist Alain Aspect and colleagues performed an experiment that confirmed the so-called Bell's Inequality Principle. Without going into the details of the experiment, I'll just say that it proved a major prediction of quantum theory, one that Einstein objected to in a famous paper describing a thought experiment that became known as the EPR (Einstein, Podolsky, Rosen) paradox. Two entangled photons can be millions of miles apart and yet, if the polarity of one photon flips, the other will flip simultaneously. To a lot of classical physicists such as Einstein, the existence of nonlocal phenomena would mean that the two photons are communicating at superluminal speeds which is a no-no. Einstein called it "spooky action at a distance." Many have refused to accept the completeness and even the correctness of QM for this reason. But the superluminal objection is flawed in my opinion, because it assumes the physical existence of space. As soon as one realizes that there is no space then it is easy to see that there is no superluminal or any sort of communication taking place between the entangled photons. Particles do not exist in space, they just exist. There is no spooky action at a distance because there is no distance between particles. This is not the same as saying that the distance is zero; distance simply does not exist: it is abstract. More precisely, it is the abstract vector difference between two positional properties. The entangled polarities are facets of the same coin. In other words, nonlocality is equivalent to nonspatiality. Nature is able to apply its principles of conservation "everywhere" because the universe is one. Not one in the sense of a single point or location (there is no location) but one in the sense of yin-yang complementarity.
