You can shelf your designs for a warp drive engine (for now) and put the DeLorean back in the garage; it turns out neutrinos may not have broken any cosmic speed limits after all.

(PhysOrg.com) -- The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges using increasingly small and complicated circuits. And while those electrical advances continue to race ahead, researchers at the University of Pennsylvania are pushing circuitry forward in a different way, by replacing electricity with light.

(PhysOrg.com) -- Under a microscope, a tiny droplet slides between two fine hairs like a roller coaster on a set of rails until — poof — it suddenly spreads along them, a droplet no more.

(PhysOrg.com) -- Sometimes knowing that a new technology works is not enough. You also must know why it works to get marketplace acceptance

A new phenomenon might make computing devices faster, smaller and much more energy-efficient. Moving so-called skyrmions needs 100,000 times smaller currents than existing technologies and the number of atoms needed for a data bit could be reduced significantly. Now a team of physicists from the Technische Universitaet Muenchen and the University of Cologne developed a simple electronic method for moving and reading these skyrmion data bits

(PhysOrg.com) -- As every young science student knows, moving objects have kinetic energy. But just how much energy does something need to move? In a new study, a pair of physicists has shown that it’s theoretically possible for a system in its lowest energy state, or ground state, to exhibit periodic motion.

(PhysOrg.com) -- Finding evidence for dark matter – the unknown substance that theoretically makes up 23% of the universe – has been one of the biggest challenges in modern cosmology. Several experiments are underway to detect dark matter candidates known as Weakly Interacting Massive Particles (WIMPs) as they travel through the Earth.

Physicist John P. Davis is counting the days until he takes delivery of equipment that will give the University of Alberta the distinction of having the coldest laboratory in Canada.

(PhysOrg.com) -- Scientists have solved one of the printing industry's greatest challenges - whether a liquid thread will break up into drops.

New research, published by the National Physical Laboratory (NPL), takes a significant step towards changing the international definition of the kilogram – which is currently based on a lump of platinum-iridium kept in Paris. NPL has produced technology capable of accurate measurements of Planck's constant, the final piece of the puzzle in moving from a physical object to a kilogram based on fundamental constants of nature. The techniques are described in a paper published in Metrologia on the 20th February.

Dilute magnetic semiconductors (DMS) have recently been a major focus of magnetic semiconductor research. A laboratory from the University of Science and Technology of China explored the feasibility of doping manganese (Mn) into zinc sulfide (ZnS) to obtain magnetic semiconductors.

(PhysOrg.com) -- In the United States, ultrafast trading in financial markets between 2006 and 2011 was the underlying factor for over 18,000 extreme price changes, according to a new study.

Quantum cryptography is the ultimate secret message service. Now new research, presented at the 2012 AAAS Annual Meeting, shows it can counter even the ultimate paranoid scenario: when the equipment or even the operator is in the control of a malicious power.

A Griffith University PhD candidate has been highly awarded for his innovative image of the shadow of a single atom.

Whether a car or a ball, the forces acting on a body moving in a straight line are very different to those acting on one moving in tight curves.
