Scientists have long known that healthy cells looked and behaved differently from cancer cells. For instance, the nuclei of healthy cells -- the inner part of the cells where the chromosomes are stored -- tend to have a rounder surface than the nuclei in cancerous cells.

Showcasing new tools for widespread development of quantum circuits made of mechanical parts, scientists from the National Institute of Standards and Technology have demonstrated a flexible, broadly usable technique for steadily calming the vibrations of an engineered mechanical object down to the quantum "ground state," the lowest possible energy level.

(PhysOrg.com) -- In what might at first seem obvious, but isn't after further thinking, a group of physicists from the United States and Canada have demonstrated, for the first time, that images generated by light, can be rotated via a rotating medium. In a paper published in Science, physicists Sonja Franke-Arnold, Graham Gibson, Robert W. Boyd and Miles J

It's like a Brownie camera for the digital age: The microscopic device fits on the head of a pin, contains no lenses or moving parts, costs pennies to make – and this Cornell-developed camera could revolutionize an array of science from surgery to robotics.

(PhysOrg.com) -- Scientists at the University of Glasgow have, for the first time, been able to drag light by slowing it down to the speed of sound and sending it through a rotating crystal.

(PhysOrg.com) -- A high-temperature superconductor can now be switched on and off within a trillionth of a second – 100 years after the discovery of superconductivity and 25 years after the first high-temperature superconductor was. A team including physicists from the University of Oxford and the Max Planck Research Group for Structural Dynamics at the University of Hamburg has realised an ultrafast superconducting switch by using intense terahertz pulses.

Scientists have taken one step closer to the next generation of computers. Research from the Cavendish Laboratory, the University of Cambridge's Department of Physics, provides new insight into spintronics, which has been hailed as the successor to the transistor.

(PhysOrg.com) -- Working out of Tokyo University, scientists in the Department of Materials Science, have developed a new metal alloy that unlike other “superelastic” alloys can resume its original shape in temperatures ranging from -196 to 249 degrees Celsius. Prior to this discovery, such alloys were only able to revert to their original form in the much narrower range of -20 to 80 degrees Celsius.

Future computers may rely on magnetic microprocessors that consume the least amount of energy allowed by the laws of physics, according to an analysis by University of California, Berkeley, electrical engineers.

Researchers can now see objects more precisely and faster at the nanoscale due to utilising the full colour spectrum of synchrotron light, opening the way for faster 3D nanoimaging.

The spreading of a liquid drop on a solid surface is a simple, everyday phenomenon. And while it is known that when a drop of oil is placed on a solid surface, its radius increases as its thickness decreases, the mechanisms underlying the process are still not well understood on a microscopic level, particularly at the moving edge between the liquid and solid, which is known as the "contact line" region.

Researchers have been investigating the connection between fifth century Himalayan instruments used in religious ceremonies and modern physics.

In this month's special issue of Physics World, which examines the science and applications of invisibility, Martin McCall and Paul Kinsler of Imperial College London describe a new type of invisibility cloak that does not just hide objects – but events.

By swapping one superconducting material for another, researchers at the National Institute of Standards and Technology (NIST) have found a practical way to boost the efficiency of the world's fastest single-photon detector, while also extending light sensitivity to longer wavelengths. The new tungsten-silicon alloy could make the ultrafast detectors more practical for use in quantum communications and computing systems, experiments testing the nature of reality, and emerging applications such as remote sensing.

(PhysOrg.com) -- John J. Chapman, a physicist working for NASA has presented an idea for a new type of fusion thruster for possible use by space traveling vehicles at the IEEE Symposium going on in Chicago this week. In the presentation, as explained on IEEE Spectrum, Chapman suggests that boron be used as an “aneutronic” fuel source, stating that doing so makes the energetic particles easier to deal with than traditional materials.
