Researchers Create an Ultrathin Invisibility Cloak
AUSTIN, Texas — Until now, the invisibility cloaks put forward by scientists have been bulky devices - an obvious flaw for those interested in Harry Potter-style applications. However, researchers at The University of Texas at Austin have developed a cloak that is just micrometers thick and can hide three-dimensional objects from microwaves in their natural environment, in all directions and from all of the observers' positions.

Researchers Use Metamaterials to Observe Giant Photonic Spin Hall Effect
Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of metamaterials - artificial nanoconstructs whose optical properties arise from their physical structure rather than their chemical composition.

Planck captures portrait of the young Universe, revealing earliest light
Satellite's first all-sky image is the most detailed picture to date of the early Universe, giving us a better understanding of its birth.

Laser-like photons signal major step towards quantum ’Internet’
The realisation of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the quantum 'Internet'. We are at the dawn of quantum-enabled technologies, and quantum computing is one of many thrilling possibilities Mete Atature The number of transistors on a microprocessor continues to double every two years, amazingly holding firm to a prediction by Intel co-founder Gordon Moore almost 50 years ago.

As fuel cells evolve, a role emerges for palladium
As fuel cells evolve, a role emerges for palladium
Researchers at Yale University have taken another step toward the development of low-temperature, lower-cost alkaline fuel cells, which are battery-like devices that convert oxygen and hydrogen into electricity and heat. In research recently published in the journal Applied Catalysis B: Environmental, Yale engineers report synthesizing a platinum-free catalyst for use in alkaline fuel cells by substituting less-costly palladium for platinum and combining it with silver.

New results indicate that particle discovered at CERN is the Higgs boson
New results indicate that particle discovered at CERN is the Higgs boson
New results from the Large Hadron Collider (LHC) indicate that the particle detected last summer is looking more and more like the Higgs boson, the particle thought to be essential for giving mass to the universe. Several Princeton University faculty members and students are directly involved in the search for the once-elusive particle.

’Nuisance’ data lead to surprising star-birth discovery
When a batch of bright cosmic objects first appeared in maps in 2008 made with data from the South Pole Telescope , astronomers at the University of Chicago's Kavli Institute for Cosmological Physics regarded it only as an unavoidable nuisance. The light sources interfered with efforts to measure more precisely the cosmic microwave background—the afterglow of the big bang.

ALMA rewrites history of Universe's stellar baby boom
Observations with the Atacama Large Millimeter/submillimeter Array (ALMA) show that the most vigorous bursts of star birth in the cosmos took place much earlier than previously thought. The results are published in a set of papers to appear and in the Astrophysical Journal. The research is the most recent example of the discoveries coming from the new international ALMA observatory, which celebrates its inauguration today.

Bursts of Star Formation in the Early Universe
Bursts of Star Formation in the Early Universe
Galaxies have been experiencing vigorous bursts of star formation from much earlier in cosmic history than previously thought, according to new observations by a Caltech-led team. These so-called starburst galaxies produce stars at a prodigious rate-creating the equivalent of a thousand new suns per year.

Auroras shine light on solar flares
Astrophysicists at the University of Glasgow are looking to the Northern and Southern Lights to expand our understanding of solar flares. In a new paper published in the Astrophysical Journal, researchers from the University's School of Physics and Astronomy suggest magnetic waves, which contribute to the formation of auroras on Earth, could help energy from solar flares travel tens of thousands of kilometres in under a second.

Hide & seek with a quantum compass
Hide & seek with a quantum compass
How would you look for something that can be in two 'places' at once? The answer, according to Oxford University research into a quantum phenomenon called superposition, seems to be to ask where it isn't rather than where it is. 'Superposition allows an atom to be simultaneously 'here' and 'there'.

New technique makes solar cells more efficient
A new technique developed by University of Toronto Engineering Professor Ted Sargent and his research group could lead to significantly more efficient solar cells. In a paper published in the journal Nano Letters , the group describes a new technique to improve efficiency in what are called colloidal quantum dot photovoltaics.

The Liverpool View: Did we discover a Higgs?
July 4th, 2012 – a landmark, red-letter day in a physicist's calendar. It was the day that CERN webcast a special seminar of the latest results from the Large Hadron Collider. It was the day when the world went particle physics mad, celebrating the discovery of the long sought and long elusive Higgs boson.

Back to basics for climate models
Basic physics and statistic tools could offer a simpler and more meaningful way to model key elements of the Earth's climate, according to researchers at the University of Leeds and Brown University. The research, published in Physical Review Letters, shows that a technique called direct statistical simulation accurately models fluid jets, fast-moving flows that form naturally in oceans and in the atmosphere.

Physicists demonstrate the acceleration of electrons by a laser in a vacuum
Physicists demonstrate the acceleration of electrons by a laser in a vacuum
David Cline, a distinguished professor in the UCLA Department of Physics and Astronomy, and Xiaoping Ding, an assistant researcher at UCLA, have conducted research at Brookhaven National Laboratory in New York and have established that an electron beam can be accelerated by a laser in free space. This has never been done before at high energies and represents a significant breakthrough, Cline said, adding that it also may have implications for fusion as a new energy source.

Palaeontologist reveals insects' colourful past
Palaeontologist reveals insects’ colourful past
An international research team led by a University of Bristol scientist has explained the preservation of colours in fossil insects for the first time. The discovery explains why colours change and why they are destroyed during fossilisation, revealing hidden gems in the insect fossil record that could help reconstruct the evolution of colours in insects.

Physicists crack science of ice formation
Physicists crack science of ice formation Salt - and just about anything else that dissolves in water, which is called a solute - lowers water's melting point, which is why it's useful for de-icing roads. And the higher the solute concentration, the slower ice forms. That's why solutes, or "cryoprotectants," are added to proteins, cells, tissues and even dead bodies to slow down ice formation during cryopreservation.

Quantum algorithm breakthrough
Quantum algorithm breakthrough
An international research group has demonstrated a quantum algorithm that performs a true calculation for the first time. Quantum algorithms could one day enable the design of new materials, pharmaceuticals or clean energy devices. The team implemented the 'phase estimation algorithm' - a central quantum algorithm which achieves an exponential speedup over all classical algorithms.

Exploring the roots of volcanic eruptions: insights from deep magmatic processes
An exploration of deep magmatic processes occurring in the Earth's crust beneath volcanoes, which could contribute to linking these physical processes at depth with volcanic eruptions at the surface, has been carried out by researchers from the University of Bristol and the Swiss Federal Institute in Zurich.
