Omega-3 improves working memory in healthy young adults

October 31, 2012

Lovaza

Researchers at the University of Pittsburgh have determined that healthy young adults ages 18–25 can improve their working memory by increasing their Omega-3 fatty acid intake.

Before they began taking the supplements, all participants were asked to perform a working memory test in which they were shown a series of letters and numbers. The young adults had to keep track of what appeared one, two,… read more

Record 100,000 entangled photons detected

October 31, 2012

quantum_correlations_singlet_bell_state

A whopping 100,000 entangled photons have been detected for the first time, beating the previous record of just 12, New Scientist reports.

The technique could be useful for safely sharing keys used in encrypted communications.

Entangled photons have linked quantum states, such that measuring the state of one photon determines the state of the others, no matter how far apart they are.

Detecting entanglement usually… read more

A new powered exoskeleton that enables people with severe spinal cord injuries to stand, walk, sit and climb stairs has been developed by Vanderbilt University’s Center for Intelligent Mechatronics. Its light weight, compact size, and modular design promise to provide users with an unprecedented degree of independence.

Parker Hannifin Corporation has signed an exclusive licensing agreement to develop a commercial version of the device, which it plans to introduce in… read more

Researchers from NYU, Harvard, and Dow Chemical have created new colloidal microparticles that spontaneously self-assemble into structures resembling molecules made from atoms.

These structures were previously impossible to make and hold promise for manufacturing advanced optical materials and ceramics, such as photonic crystals that could improve displays and computer chips.

The method was developed by a team of chemists, chemical engineers, and physicists at New York University (NYU), the Harvard School of… read more

Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today.

“Carbon has the potential to deliver high performance at a low cost,” said study senior author Zhenan Bao, a professor of chemical engineering at Stanford.

“To the best of our knowledge, this is the first demonstration of… read more

’1000 genomes barrier’ broken

Will help researchers interpret genetic changes in people with disease
November 1, 2012

population_variants

A landmark project that has sequenced 1,092 human genomes from individuals around the world will help researchers to interpret the genetic changes in people with disease.

This first study to break the “1000 genomes barrier” will enable scientists to begin to examine genetic variations at the scale of the populations of individual countries, as well as guiding them in their search for the rare genetic variations related… read more
