Getting around the Uncertainty Principle: Physicists make first direct measurements of polarization states of light

Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both overcomes some important challenges of Heisenberg's famous Uncertainty Principle and also is applicable to qubits, the building blocks of quantum information theory.

Weak measurement: as light goes through a birefringent crystal the horizontally and vertically polarized components of light spread out in space, but an overlap between the two components remains when they emerge. In a “strong” measurement the two components would be fully separated.

Five Major Mental Disorders Share Genetic Roots

Overlap Blurs Diagnostic Categories – NIH-funded Study

Five major mental disorders share some of the same genetic risk factors, the largest genome-wide study of its kind has found. Evidence for such genetic overlap had previously been limited to pairs of disorders.

Supermassive Black Hole Spins Super-Fast

balck hole_0.png
In this artist's conception a supermassive black hole is surrounded by a hot accretion disk, while some inspiraling material is funneled into a wispy blue jet. New measurements show that the black hole at the center of galaxy NGC 1365 is spinning at close to the maximum possible rate. This suggests that it grew via "ordered accretion" rather than by swallowing random blobs of gas and stars.

UK invests £88 million in world’s largest ever optical telescope

The UK research base and industry will be playing a leading role in one of the biggest global science collaborations in history, after the government confirmed long-term investment in the European Extremely Large Telescope (E-ELT) to be built in Chile.

The E-ELT will make huge strides toward our understanding of the Universe, the effects of dark matter and energy and planets outside of the solar system. Its 39 metres in diameter mirror will collect 15 times more light than any existing telescope and it will produce images 16 times sharper than the Hubble space-based telescope.

Future soldiers will have plastic electronic sensors embedded in their helmets and uniforms. Research has brought electronics to flexible plastic through the combined efforts of industry, academia and Army scientists.
The Army’s goal was to get this amazing technology into the hands of soldiers.

The Birth of a Giant Planet?

Candidate protoplanet spotted inside its stellar womb

eso1310a_0.jpg
Astronomers using ESO’s Very Large Telescope have obtained what is likely the first direct observation of a forming planet still embedded in a thick disc of gas and dust. If confirmed, this discovery will greatly improve our understanding of how planets form and allow astronomers to test the current theories against an observable target.
