Members of the international STAR collaboration at the Relativistic Heavy Ion Collider -- a particle accelerator used to recreate and study conditions of the early universe at the U.S. Department of Energy's Brookhaven National Laboratory -- have detected the antimatter partner of the helium nucleus: antihelium-4.

Scientists recognize how important a role electrical fields play in nature and technical areas. By adjusting these fields, the transmission of nerve impulses becomes possible and the operation of modern data storage is fulfilled by saving electrical charges (so-called Flash Memories)

(PhysOrg.com) -- Spintronics — also known as magnetoelectronics — may replace electronics as the medium of choice for computer memory. The discovery of a mechanism that produces permanent magnets at room temperature, without any external influence, may soon improve the design of spintronic devices. Takumi Ohtsuki from the RIKEN SPring-8 Center, Harima and his colleagues in Japan, made the discovery in a class of material called a dilute ferromagnetic oxide.

It's ubiquitous. It's universal. And it's understood—not! Water's choices in a given situation often defy scientific predictions.

(PhysOrg.com) -- Around midnight this night CERN's Large Hadron Collider set a new world record for beam intensity at a hadron collider when it collided beams with a luminosity of 4.67 x 1032cm-2s-1. This exceeds the previous world record of 4.024 x 1032cm-2s-1, which was set by the US Fermi National Accelerator Laboratory's Tevatron collider in 2010, and marks an important milestone in LHC commissioning.

(PhysOrg.com) -- Some chemical elements appear much more abundantly in nature than others, which is partly due to how the elements originally formed. Scientists know that the light elements (hydrogen, deuterium, helium, and traces of lithium) were produced by fusion in the early Universe. Today, lithium, beryllium, and boron are constantly being produced in cosmic rays, while the heavier elements (up to iron) are formed by fusion in stars.

(PhysOrg.com) -- Did the early universe have just one spatial dimension? That's the mind-boggling concept at the heart of a theory that University at Buffalo physicist Dejan Stojkovic and colleagues proposed in 2010.

For more than 150 years, spark plugs have powered internal combustion engines. Automakers are now one step closer to being able to replace this long-standing technology with laser igniters, which will enable cleaner, more efficient, and more economical vehicles.

(PhysOrg.com) -- Scientists have demonstrated for the first time that atoms can be guided in a laser beam and possess the same properties as light guided in an optical communications fiber.

In 1964, physicist Richard Feynman delivered a series of lectures titled “On the Nature of Physical Law.” Feynman delivered these seven one-hour lectures at Cornell in 1964, and the BBC taped them.

Researchers at the University of California, Santa Barbara, say they've figured out the cause of a problem that's made light-emitting diodes (LEDs) impractical for general lighting purposes. Their work will help engineers develop a new generation of high-performance, energy-efficient lighting that could replace incandescent and fluorescent bulbs.

Using well-known patterned media, a team of researchers in France has figured out a way to double the areal density of information by essentially cutting the magnetic media into small pieces and building a "3D tower" out of it.

Invisibility cloaks are seemingly futuristic devices capable of concealing very small objects by bending and channeling light around them.

University of California-Irvine researcher Zhihong Lin is using the Jaguar supercomputer at Oak Ridge National Laboratory to study fusion reactions, which produce helium from hydrogen and release energy in the process, in hopes of igniting ITER, an experimental fusion reactor being built in southern France.
