Newlyweds, be careful what you wish for
A statistical analysis of the gift 'fulfillments' at several hundred online wedding gift registries suggests that wedding guests are caught between a rock and a hard place when it comes to buying an appropriate gift for the happy couple.

Progress in the fight against quantum dissipation
Scientists at Yale have confirmed a 50-year-old, previously untested theoretical prediction in physics and improved the energy storage time of a quantum switch by several orders of magnitude. They report their results in the April 17 issue of the journal Nature.

At the origin of cell division
Movement and the ability to divide are two fundamental traits of living cells. The origin of these abilities could rely on very simple physical mechanisms, which have been simulated by scientists of the International School for Advanced Studies of Trieste in a study just published in Physical Review Letters. Luca Giomi and Antonio DeSimone have reproduced motility in their models, by acting on a single parameter until they caused the 'cells' to divide spontaneously without the action of external forces.

Ant colonies help evacuees in disaster zones
An escape route mapping system based on the behavior of ant colonies could give evacuees a better chance of reaching safe harbor after a natural disaster or terrorist attack by building a map of showing the shortest routes to shelters and providing regular updates of current situations such as fires, blocked roads or other damage via the smart phones of emergency workers and those caught up in the disaster.

Scientists explain how memories stick together
Scientists at the Salk Institute have created a new model of memory that explains how neurons retain select memories a few hours after an event. This new framework provides a more complete picture of how memory works, which can inform research into disorders liked Parkinson's, Alzheimer's, post-traumatic stress and learning disabilities.

Earthquake simulation tops 1 quadrillion flops

Sensitive detection method may help impede illicit nuclear trafficking
According to a new study in the Journal of Applied Physics, coupling commercially available spectral X-ray detectors with a specialized algorithm can improve the detection of uranium and plutonium in small, layered objects such as baggage. This approach may provide a new tool to impede nuclear trafficking.

Nobel prize candidates wait often over 20 years to win their prize
Candidates for a Nobel prize often have to wait more than 20 years to receive this highest of scientific accolades. According to a Correspondence by Santo Fortunato of Aalto University in Finland and colleagues, such nail-biting delays are becoming the norm -- to the point that aspiring laureates may themselves have expired by the time the medal is due to be presented.

Using mathematics to beat jetlag effectively
Our 'internal clock' is predicted to shift more rapidly than previously thought. In a study published in PLOS Computational Biology on April 10, researchers present schedules of light exposure that may shift our circadian clock in the minimum time, simply by adjusting the timing of the beginning and end of each day.

Pseudo-mathematics and financial charlatanism
'Backtest overfitting' is a dubious yet common practice in finance. Its perils are dissected in 'Pseudo-Mathematics and Financial Charlatanism: The Effects of Backtest Overfitting on Out-of-Sample Performance,' to appear in the Notices of the American Mathematical Society. The authors write: 'We strongly suspect that ... backtest overfitting is a large part of the reason why so many algorithmic or systematic hedge funds do not live up to the elevated expectations generated by their managers.'

New epidemiology model combines multiple genomic data

Is the power grid too big?
Researchers are asking whether there is a 'right' size for the US power grid; they believe that smaller grids would reduce the likelihood of severe outages, such as the 2003 Northeast blackout, likening the grid behavior to sandpiles: 'Sandpiles are stable until you get to a certain height. Then you add one more grain and the whole thing starts to avalanche.'

Math modeling integral to synthetic biology research
A long-standing challenge in synthetic biology has been to create gene circuits that behave in predictable and robust ways. Mathematical modeling experts from the University of Houston collaborated with experimental biologists at Rice University to create a synthetic genetic clock that keeps accurate time across a range of temperatures. Funded by the National Institutes of Health, the findings were published in a recent issue of the Proceedings of the National Academy of Sciences.
