Tunable windows for privacy, camouflage
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a technique that can quickly change the opacity of a window, turning it cloudy, clear or somewhere in between with the flick of a switch.

Light illuminates the way for bio-bots
A new class of miniature biological robots, or bio-bots, has seen the light -- and is following where the light shines. The bio-bots are powered by muscle cells that have been genetically engineered to respond to light, giving researchers control over the bots' motion, a key step toward their use in applications for health, sensing and the environment.

Carbon from land played a role during last deglaciation
As the Earth emerged from its last ice age several thousand years ago, atmospheric carbon dioxide increased and further warmed the planet. Scientists have long speculated that the primary source of this CO2 was from the deep ocean around Antarctica, though it has been difficult to prove. A study published this week confirmed that theory.

ROBO1 helps cells put up stiff resistance
A protein called ROBO1 may delay the progression of breast cancer, according to a paper published in The Journal of Cell Biology. The study, 'Loss of miR-203 regulates cell shape and matrix adhesion through ROBO1/Rac/FAK in response to stiffness' by Lily Thao-Nhi Le and colleagues, identifies a signaling pathway that may protect breast cells from the tumorigenic effects of stiff extracellular matrices.

Where we live affects our bias against mixed-race individuals, psychology study finds
Whites living in areas where they are less exposed to those of other races have a harder time categorizing mixed-race individuals than do Whites with greater interracial exposure, a condition that is associated with greater prejudice against mixed-race individuals, a new experimental study shows.

Fighting world hunger: MU team receives $4 million NSF grant to advance crop research
Developing drought-tolerant corn varieties that make efficient use of available water is vital to sustain the estimated 9 billion global population by 2050. For the past several decades, University of Missouri researchers have been working to solve this world hunger problem and have made significant strides. Now, the National Science Foundation has awarded MU a $4.2 million grant to fund a four-year project to study how corn maintains root growth in drought conditions.

Down the rabbit hole: How electrons travel through exotic new material
Researchers at Princeton University have observed a bizarre behavior in a strange new crystal that could hold the key for future electronic technologies. Unlike most materials in which electrons travel on the surface, in these new materials the electrons sink into the depths of the crystal through special conductive channels.

Developing multiline anchor system for floating offshore wind turbines
The principal goal of the research is to develop offshore floating wind farms where the individual floating wind turbines are moored using a networked series of anchors and cables that hold the entire wind farm in place. Currently, each floating wind turbine has its own individual anchoring system. The proposed networked system would save money and require fewer anchors and geotechnical site investigations, the researchers say.

How stick insects handle indigestive food
Plant cell walls are comprised of many complex polymers that require multiple different enzymes to fully break down, such as cellulase to digest cellulose and xylanase to digest xylan. For decades scientists thought only microbes could produce cellulase, until cellulase genes were found in wood-feeding insects. Now, researchers from the Max Planck Institute for Chemical Ecology in Jena, Germany, discovered that stick insects produce cellulases that can handle several types of cell wall polymers equally.

Smartphone security: Why doodling trumps text passwords
Someday soon, you may be able to log into your smartphone with sweeping gestures or doodling, using one or more fingers. Rutgers University researchers have performed the first study of free-form gesture passwords for smartphones in the field. Such passwords allow people to draw a password of any shape with any number of fingers. Gesture, or doodling, passwords are very suitable for touchscreens, faster to use, easy to remember and hard to guess.

Major source of methanol in the ocean identified
As one of the most abundant organic compounds on the planet, methanol occurs naturally in the environment as plants release it as they grow and decompose. It is also found in the ocean, where it is a welcome food source for ravenous microbes that feast on it for energy and growth.
