Developmental Science
Learning by watching, toddlers show intuitive understanding of probability
Most people know children learn many skills simply by watching people around them. Without explicit instructions youngsters know to do things like press a button to operate the television and twist a knob to open a door. Now researchers have taken this further, finding that children as young as age two intuitively use mathematical concepts such as probability to help make sense of the world around them.

Psychological Science
Anticipating experience-based purchases more enjoyable than material ones
To get the most enjoyment out of our dollar, science tells us to focus our discretionary spending on trips over TVs, on concerts over clothing, since experiences tend to bring more enduring pleasure than do material goods. New research shows that the enjoyment we derive from experiential purchases may begin before we even buy. The findings are published in Psychological Science, a journal of the Association for Psychological Science.

'Robo Brain' will teach robots everything from the Internet
Robo Brain -- a large-scale computational system that learns from publicly available Internet resources -- is currently downloading and processing about 1 billion images, 120,000 YouTube videos, and 100 million how-to documents and appliance manuals. The information is being translated and stored in a robot-friendly format that robots will be able to draw on when they need it.

800 meters beneath Antarctic ice sheet, subglacial lake holds viable microbial ecosystems
According to LSU's Brent Christner, the paper's lead author and a researcher with the NSF-funded Whillans Ice Stream Subglacial Access Research Drilling, or WISSARD, project, 'hidden beneath a half-mile of ice in Antarctica is an unexplored part of our biosphere. WISSARD has provided a glimpse of the nature of microbial life that may lurk under more than five million square miles of ice sheet.'

Hot-spring bacteria reveal ability to use far-red light for photosynthesis
Bacteria growing in near darkness use a previously unknown process for harvesting energy and producing oxygen from sunlight, a research team led by a Penn State University scientist has discovered. The discovery lays the foundation for further research aimed at improving plant growth, harvesting energy from the sun, and understanding dense blooms like those now occurring on Lake Erie and other lakes worldwide.

Sunlight, not microbes, key to CO2 in Arctic
The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide after entering the freshwater system in a process thought to be controlled largely by microbial activity. However, researchers say that sunlight and not bacteria is the key to triggering the production of CO2 from material released by Arctic soils.

Researchers map quantum vortices inside superfluid helium nanodroplets
Scientists have, for the first time, characterized so-called quantum vortices that swirl within tiny droplets of liquid helium. The research, led by scientists at the US Department of Energy's Lawrence Berkeley National Laboratory , the University of Southern California, and SLAC National Accelerator Laboratory, confirms that helium nanodroplets are in fact the smallest possible superfluidic objects and opens new avenues to study quantum rotation.
