Using a microscope the size of a football field, researchers from The University of Western Ontario are studying why some insects can survive freezing, while others cannot. http://www.physorg.com/news180350816.html Biology Fri, 18 Dec 2009 09:27:47 EST news180350816 To exploit the quantum world to the fullest, a key commodity is entanglement -the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another. Now, physicists at the Joint Quantum Institute (JQI), a collaborative organization of the National Institute of Standards and Technology and the University of Maryland, have developed a promising new source of entangled photons using quantum dots tweaked with a laser. The JQI technique may someday enable more compact and convenient sources of entangled photon pairs than presently available for quantum information applications such as the distribution of "quantum keys" for encrypting sensitive messages. http://www.physorg.com/news177763808.html Physics Wed, 18 Nov 2009 10:50:39 EST news177763808 (PhysOrg.com) -- Scientists at the U.S. Department of Energy`s (DOE) Argonne National Laboratory have refined a technique to manufacture solar cells by creating tubes of semiconducting material and then "growing" polymers directly inside them. The method has the potential to be significantly cheaper than the process used to make today`s commercial solar cells. http://www.physorg.com/news177092235.html Nanotechnology Tue, 10 Nov 2009 16:17:54 EST news177092235 (AP) -- Four years after its first solar sail ended up in the ocean instead of orbit, The Planetary Society announced Monday that by the end of 2010 it will try again to launch a spacecraft that will be propelled by the subtle pressure of sunlight. http://www.physorg.com/news177020675.html Space & Earth Mon, 09 Nov 2009 21:00:01 EST news177020675 Collaborative users from the Advanced Photon Source at the Argonne National Laboratory, working with the Electronic & Magnetic Materials & Devices Group, have found a controllable way to modify the surfaces of pristine Nb-doped SrTiO3 (Nb:STO) at the nanoscale. http://www.physorg.com/news176573506.html Nanotechnology Wed, 04 Nov 2009 16:30:03 EST news176573506 (PhysOrg.com) -- Many scientists believe that quantum entanglement is required in order for effective quantum computing. Entanglement takes place when there is a connection that exists between two objects - even when they are spatially separated - that allows what happens to one to happen to the other. The link is such that each entangled object cannot be adequately described without its counterpart. So far, entangling qubits for practical use has been difficult, since scientists want to be able to entangle several qubits at once. http://www.physorg.com/news176364815.html Physics Mon, 02 Nov 2009 11:20:01 EST news176364815 Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA's orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. The dead-heat finish may stoke the fires of debate among physicists over Einstein's special theory of relativity because one of the photons possessed a million times more energy than the other. http://www.physorg.com/news175965994.html Physics Wed, 28 Oct 2009 16:27:56 EST news175965994 During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. It captured more than one thousand discrete sources of gamma rays -- the highest-energy form of light. Capping these achievements was a measurement that provided rare experimental evidence about the very structure of space and time, unified as space-time in Einstein's theories. http://www.physorg.com/news175961092.html Space & Earth Wed, 28 Oct 2009 15:06:24 EST news175961092 (PhysOrg.com) -- European researchers have created a world-leading camera in CMOS that can record photons at a million times a second.

Unfortunately, the fragility of methods for storing and sending quantum information has so far frustrated the enterprise. Now a team of physicists in Sweden and Poland have shown that photons that encode data have strength in numbers. Their experiment is reported in Physical Review Letters and Physical Review A and highlighted in the October 5 issue of Physics. http://www.physorg.com/news173964594.html Physics Mon, 05 Oct 2009 12:30:22 EST news173964594 (PhysOrg.com) -- European researchers have created a CMOS (semiconductor) camera capable of filming individual photons one million times a second.

Usually, detecting quantum phenomena requires sensitive photon detectors or similar technology, keeping the quantum world far removed from our everyday experience. By showing that it`s possible to perform quantum optics experiments with human eyes as detectors, the physicists can bring quantum phenomena closer to the macroscopic level and to everyday life. http://www.physorg.com/news173423784.html Physics Tue, 29 Sep 2009 09:10:03 EST news173423784 Researchers at Ben-Gurion University of the Negev have developed thin films that exhibit carrier multiplication (CM).

Particles can exist in "superposition," in more than one state at the same time (as long as we don't look), a situation that permitted Schrödinger's famed cat to be simultaneously alive and dead; matter can be "entangled" -- Albert Einstein called it "spooky action at a distance" -- such that one thing influences another thing, regardless of how far apart the two are. http://www.physorg.com/news164885583.html Physics Mon, 22 Jun 2009 10:34:04 EST news164885583 (PhysOrg.com) -- While information technology is generally thought to require electrons or photons for transmitting information, scientists have recently demonstrated a third method of transmission: chemical reactions.
