CERN's particle accelerator, the Large Hadron Collider (LHC), was restarted this weekend after 14 months of repairs. Particle beams are once again circulating in the world's most powerful accelerator.
In 1915, Albert Einstein launched his general relativity, a new theory of gravity that completed the one formulated by Newton in 1687. Since then, it has been the standard theory of gravity, the foundation on which cosmology rests. But is it the final one?
Engineer Charles K. Kao has been awarded the Nobel Prize in Physics for his contributions to communication through fiber optics. Along with him have been awarded Willard Boyle and George Smith, from Bell Laboratories, for CCD devices.
American scientists have captured the image of a huge lightning bolt that, instead of hitting the ground, went up into the clouds. These rare weather events (only 5 have been recorded since 2001) are known as "giant jets".
When raindrops hit the ground they do so in a wide variety of sizes. A study with high-speed cameras carried out at the Aix-Marseille University in Marseille (France) has revealed the physical process behind this diversity.
Two teams of researchers, at the University of California at Berkeley and at Cornell University in New York, have designed "invisibility mats" that visually hide the presence of any object that is placed under them.
Scientists from the University of California (Berkeley) and Cornell University have created miniature invisibility cloaks that could emulate that of Harry Potter himself.
At the University of Colorado they have used strontium atoms to create the most accurate atomic clock: it would not even lose a second after 300 million years of eventual operation.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
