Underwater Turbines Tap Moon’s Gravity to Generate Power

February 11, 2014 10:07 pm | by General Electric | News | Comments

When Mark Baker looks up at the moon at night, he does not see magic or mystery. He ponders megawatts. Twice a day, like clockwork, the moon’s gravity makes the seas ebb and flow. For Baker, a marine renewables business manager at GE Power Conversion, the tides are the perfect source of energy, more predictable and reliable than wind or solar power. “Some U.K. locations have significant tidal head...

Source of 'Moon Curse' Revealed by Eclipse

February 11, 2014 2:32 pm | by University of California - San Diego | News | Comments

Strange events have long been linked to nights of a full moon, though careful scrutiny dispels any association. So, when signals bounced off the lunar surface returned surprisingly faint echoes on full moon nights, scientists sought an explanation in reason rather than superstition. Still, the most compelling evidence arrived during another event that once evoked irrational fears — on a night when Earth's shadow eclipsed the full moon.

Older Brains Slow Due to Greater Experience, Rather Than Cognitive Decline

January 21, 2014 2:30 pm | by Wiley | News | Comments

What happens to our cognitive abilities as we age? Traditionally it is thought that age leads to a steady deterioration of brain function, but new research in Topics in Cognitive Science argues that older brains may take longer to process ever increasing amounts of knowledge, and this has often been misidentified as declining capacity.

Peeking into Schrödinger's Box: Direct Quantum State Measurements

January 20, 2014 2:28 pm | by University of Rochester | News | Comments

Until recently, measuring a 27-dimensional quantum state would have been a time-consuming, multistage process using a technique called quantum tomography, which is similar to creating a 3-D image from many 2-D ones. Researchers at the University of Rochester have been able to apply a recently developed, alternative method called direct measurement to do this in a single experiment with no post-processing.

Old Mathematical Puzzle may Soon be Unraveled

January 16, 2014 2:53 pm | by University of Montreal | News | Comments

It is one the oldest mathematical problems in the world. Several centuries ago, the twin primes conjecture was formulated. As its name indicates, this hypothesis deals with prime numbers, those divisible only by themselves and by one. Under this assumption, there exists an infinite number of pairs of prime numbers whose difference is two, called twin primes, but nobody has been able to confirm this so far.

Striking New Observations of Supernova Super Dust Factory

January 7, 2014 9:55 am | by National Radio Astronomy Observatory (NRAO) | News | Comments

Galaxies can be remarkably dusty places and supernovas are thought to be a primary source of that dust, especially in the early Universe. Direct evidence of a supernova’s dust-making capabilities, however, has been slim and cannot account for the copious amount of dust detected in young, distant galaxies.
