New insights into the survival and transmission strategy of malaria parasites
Malaria parasites exploit the function of the epigenetic regulator HP1 to promote survival and transmission between human hosts, a new study shows. Using HP1 the parasite controls expression of surface antigens to escape immune responses in the infected victim. This prolongs survival of the parasite in the human blood stream and secures its transmission via mosquitoes. The study paves important avenues for new intervention strategies to prevent severe disease and malaria transmission.

Minke whales lunge 100 times/hour to feed under sea ice
Minke whales are one of the most common whales in Antartica, but also one of the most vulnerable. Little was known about how these small whales feed until Ari Friedlaender and colleagues attached tags to two animals that measured their movements showing that the whales do not need to be killed to study their feeding behaviour and that they perform over 100 lunges per hour under the sea ice.

Mouth bacteria can change its diet, supercomputers reveal
Mouth bacteria can change their metabolism in disease versus health. The Stampede and Lonestar supercomputers compared gene expression of 160,000 genes in healthy and diseased periodontal communities. Research paves way for biomarkers to predict illness from wide-ranging diseases such as periodontitis, diabetes, and Crohn's disease. The Stampede supercomputer is funded by the National Science Foundation through award ACI-1134872.

University of Oklahoma professor awarded NSF CAREER grant to create visualization tools
A University of Oklahoma professor is creating innovative new ways for people to interact with data in the digital humanities with a five-year, $496,124 National Science Foundation CAREER grant. The University of Oklahoma project will greatly expand the usefulness of data visualizations by providing a general way to create, edit, search and query data inside the visualizations themselves.

No excess baggage: Antarctic insect's genome, newly sequenced, is smallest to date
Scientists who sequenced the genome of the Antarctic midge suspect the genome's small size -- the smallest in insects described to date -- can probably be explained by the midge's adaptation to its extreme living environment.

A global temperature conundrum: Cooling or warming climate?
When the Intergovernmental Panel on Climate Change recently requested a figure for its annual report, the University of Wisconsin-Madison's Zhengyu Liu knew that was going to be a problem. Writing in the journal Proceedings of the National Academy of Sciences today, Liu and his colleagues describe a consistent global warming trend over the course of the Holocene counter to a study published last year that described a period of global cooling before human influence.

Rutgers researchers show that how fast you drive might reveal exactly where you are going
Some drivers are letting auto insurance companies monitor their driving habits in return for a premium discount, but these drivers may not know that the information could reveal where they are driving. Rutgers engineers have shown that even without GPS or other location-sensing technology, a driver could reveal where he or she traveled with no more information than a starting location and a steady stream of data that shows how fast the person was driving.

Study measures steep coastal costs of China's GDP growth
Economic reforms declared in 1978 led to a surge of growth in China, but resulting increases in human impact activities are seriously degrading the nation's coastal ecosystems, according to a newly published analysis of economic and environmental data. Some activities may have reached a turning point, but others will need policy changes, the authors project.

What does 'diversity' mean to you? The answer may depend on your race
Researchers from the University of California at Irvine, the University of Virginia, and the University of California at Los Angeles collaborated to study how whites, Asian-Americans, and African-Americans evaluate diversity. The research included three studies, and participants were asked to rate the diversity of various groups of people that were presented as a team at work.

Northern Pacific's tropical anoxic zone might shrink from climate change
A commonly held belief that global warming will diminish oxygen concentrations in the ocean looks like it may not be entirely true. According to new research published in Science magazine, just the opposite is likely the case in the eastern tropical northern Pacific, with its anoxic zone expected to shrink in coming decades because of climate change.

Robot folds itself up and walks away
A team of engineers used little more than paper and Shrinky dinks -- the classic children's toy that shrinks when heated -- to build a robot that assembles itself into a complex shape in four minutes flat, and crawls away without any human intervention. The advance, described in Science, demonstrates the potential to quickly and cheaply build sophisticated machines that interact with the environment, and to automate much of the design and assembly process.

Learning from origami to design new materials
A challenge increasingly important to physicists and materials scientists in recent years has been how to design controllable new materials that exhibit desired physical properties rather than relying on those properties to emerge naturally, says University of Massachusetts Amherst physicist Christian Santangelo. Now he and physicist Arthur Evans and polymer scientist Ryan Hayward at University Massachusetts Amherst, with others, are using origami-based folding methods for 'tuning' the fundamental physical properties of any type of thin sheet.

Gut microbes browse along a gene buffet
A detailed examination of gene expression in the guts of mice raised under three different microbial conditions shows that the host organism controls which genes are made available to gut microbes at various portions of the intestine. Usage of particular genes is regulated by the microbes, but access to the genes is determined by the host.
