New technique controls dimensions of gold nanorods while manufacturing on a large scale
North Carolina State University researchers have a developed a technique for efficiently producing nanoscale gold rods in large quantities while simultaneously controlling the dimensions of the nanorods and their optical properties. The optical properties of gold nanorods make them desirable for use in biomedical applications ranging from imaging technologies to cancer treatment.

A vexing math problem finds an elegant solution
A famous math problem that has vexed mathematicians for decades has met an elegant solution by Cornell University researchers. Graduate student Yash Lodha, working with Justin Moore, professor of mathematics, has described a geometric solution for the von Neumann-Day problem, first described by mathematician John von Neumann in 1929.

Penn produces graphene nanoribbons with nanopores for fast DNA sequencing
Researchers at the University of Pennsylvania have made an advance towards realizing a new gene sequencing technique based on threading DNA through a tiny hole in a layer of graphene. Earlier versions of the technique only made use of graphene's unbeatable thinness, but the Penn team's research shows how the material's unique electrical properties may be employed to make faster and more sensitive sequencing devices.

Promiscuous mouse moms bear sexier sons
University of Utah biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young: They attract more females by making more urinary pheromones, but smelling sexier shortens their lives.

'Virtual reality hands' may help stroke survivors recover hand function
Scientists used brain-computer interface technology to help stroke survivors use their minds to power "virtual reality hands" to help regain the use of their arms and hands. The technology offers hope of recovery to stroke survivors and others who have lost mobility and control of their arms and hands.

Volcano discovered smoldering under a kilometer of ice in West Antarctica
A temporary seismic array in Marie Byrd Land in West Antarctica recorded two bursts of activity in 2010 and 2011. Careful analysis of the events shows they originate from a subglacial volcano at the leading end of a volcanic mountain chain. The volcano is unlikely to erupt through the kilometer of ice that covers it but it will melt enough ice to change the way the ice in its vicinity flows.

No peak in sight for evolving bacteria
There's no peak in sight -- fitness peak, that is -- for the bacteria in Richard Lenski's Michigan State University lab. Lenski, MSU Hannah Distinguished Professor of Microbiology and Molecular Genetics, has been running his evolutionary bacteria experiment for 25 years, generating more than 50,000 generations. In a paper published in the current issue of Science, Michael Wiser, lead author and MSU graduate student in Lenski's lab, compares it to hiking.

Scientists nearing forecasts of long-lived wildfires
Scientists have developed a new computer modeling technique that offers the promise, for the first time, of producing continually updated daylong predictions of wildfire growth throughout the lifetime of long-lived blazes. The technique, developed by a research team led by NCAR, combines detailed computer simulations with newly available satellite observations.

Amazon rainforest more able to withstand drought than previously thought
New research suggests that the Amazon rainforest may be more able to cope with dry conditions than previously predicted. Researchers at the University of Exeter and Colorado State University used a computer model to demonstrate that, providing forest conservation measures are in place, the Amazon rainforest may be more able to withstand periods of drought than has been estimated by other climate models.

Accidental discovery dramatically improves electrical conductivity
Quite by accident, Washington State University researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light. The effect, which lasted for days after the light was turned off, could dramatically improve the performance of devices like computer chips.
