Physicists Investigate Controversy over Room-Temperature Ice

(PhysOrg.com) -- By confining water in nano-sized spaces, physicists from Leiden University in the Netherlands have turned water into ice at room temperature. While it’s not the first time scientists have created room-temperature ice, Dutch physicists K. B. Jinesh and Joost Frenken hope that their findings will put the controversial subject of water under nanoscale confinement in a new light.

Theorists Make Quantum Communications Breakthrough

KentuckyFC writes "One of the cornerstones of modern physics is Claude Shannon's theory of communication, which he published in 1948. If you've ever made a phone call, watched TV, or used a computer, you've got Shannon to thank for describing how information can be moved from one place in the universe to another using an idea called the channel capacity. But nobody has been able to develop a quantum version of this theory. So physicists have no idea how much quantum information can be sent from one point to another. Now two American physicists have made an important breakthrough by proving that two quantum channels with zero capacity can carry information when used together. That's interesting because it indicates that physicists may have been barking up the wrong tree with this problem: it implies that the quantum capacity of a channel d

Physicists Find That Size Matters When Initiating an Object's Movement Through Grains

Physicists have discovered that the size of grains, such as sand, above a buried object is important in determining the force required to begin raising the object. No one, until now, has discovered how much force is required to initiate an object's movement through grains. The discovery may be useful for engineering foundations for objects such as power-line towers, or for designing industrial mixer blades, such as those used in pharmaceutical processing. Full Story

Physicists Seek Answers to Quantum Correlations

Physicists sent two photons down optical fibers toward different destinations and found that the photons could instantly sense each otheracutes behavior.

Physicists create, control photons

U.S. physicists say they've created, for the first time, controllable microwave photons and stored them in a superconducting microwave resonator.

Physicists' Analysis Leads to Discovery of New Particle

University of Michigan physicists played a leading role in the discovery of a new particle, the Omega b baryon, which is an exotic relative of the proton. It was detected for the first time in a particle accelerator at Fermi National Accelerator Laboratory (Fermilab) in Illinois, Fermilab has announced.

Physicists Find That Size Matters When Initiating An Object's Movement Through Grains

A team of Penn State physicists has discovered that the size of grains, such as sand grains, under which an object is buried is important in determining the force required to begin raising the object. No one, until now, has discovered how much force is required to initiate an object's movement through grains.

SANTA BARBARA, Calif., Aug. 6 (UPI) -- U.S. physicists say they've created, for the first time, controllable microwave photons and stored them in a superconducting microwave resonator.

Physicists urge U.S. to prioritize energy efficiency

The U.S. can reduce its dependence on foreign oil and greenhouse gas emissions by making cars and buildings much more energy efficient, according to a study released Tuesday by a large national association of physicists.

UA Physicists Thrilled at First Beam in Large Hadron Collider

UA physicists will give a free public lecture tonight to celebrate the start-up of the Large Hadron Collider, the most powerful particle accelerator ever built.

Top Physicists Ponder on the Idea of Universe in an Atom

Theoretical thinking certainly received a forward push in Monday's historic conference at Stanford University. World's brightest physicists gathered there to expose and discuss their revolutionary theories. Among the weirdest ideas stated was the one that suggests our universe is just a tiny atom in something way vaster.

Physicists pull off the gecko's feat

For years scientists have tried — and failed — to engineer materials that would enable robots to mimic the gecko’s ability to scale walls, windows and seemingly any other surface. Now, a team from the US has developed a nanotube material that is not just a match for gecko feet but 10 times more adhesive.

Physicists Rule Out the Production of Dangerous Black Holes at the LHC

(PhysOrg.com) -- On August 8, the world's largest particle accelerator, the Large Hadron Collider near Geneva, Switzerland, began the process of slowly throttling to full power. When its proton beams are circling at full speed and collisions begin, scientists from around the world will finally be able to start collecting data.

Physicists 'See' Single Top Quarks at the Tevatron

(PhysOrg.com) -- Scientists at the world's largest fully operating particle accelerator, the Tevatron at Fermi National Accelerator Laboratory (Fermilab) in Illinois, have discovered convincing evidence suggesting the existence of top quarks that are not coupled to their antiparticle, the antitop. These "single" top quarks have been hunted since Fermilab scientists first discovered top-antitop pairs in 1995.
