Your 'anonmyized' web browsing history may not be anonymous
Researchers wrote computer programs that found patterns among anonymized data about web traffic and used those patterns to identify individual users. The researchers note web users with active social media are vulnerable to the attack. 'Given a history with 30 links originating from Twitter, we can deduce the corresponding Twitter profile more than 50 percent of the time.'

Creating atomic scale nanoribbons
A recent study conducted by researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois and the Department of Chemistry at the University of Nebraska-Lincoln has demonstrated the first important step toward integrating atomically precise graphene nanoribbons (APGNRs) onto nonmetallic substrates. The paper, 'Solution-Synthesized Chevron Graphene Nanoribbons Exfoliated onto H:Si(100),' was published in Nano Letters.

Geosciences-inspired engineering
The Mackenzie Dike Swarm and the roughly 120 other known giant dike swarms located across the planet may also provide useful information about efficient extraction of oil and natural gas in today's modern world. To explore how naturally occurring dike swarms can lead to improved methods of oil and gas reservoir stimulation, the National Science Foundation Division of Earth Sciences awarded a $310,000 award to Andrew Bunger at Pitt's Swanson School of Engineering.

New low-cost technique converts bulk alloys to oxide nanowires
A simple technique for producing oxide nanowires directly from bulk materials could dramatically lower the cost of producing the one-dimensional nanostructures. That could open the door for a broad range of uses in lightweight structural composites, advanced sensors, electronic devices -- and thermally stable and strong battery membranes able to withstand temperatures of more than 1,000 degrees Celsius.

Climate change prompts Alaska fish to change breeding behavior
A new University of Washington study finds that one of Alaska's most abundant freshwater fish species is altering its breeding patterns in response to climate change, which could impact the ecology of northern lakes that already acutely feel the effects of a changing climate.

Mandarin makes you more musical?
Mandarin makes you more musical -- and at a much earlier age than previously thought. That's the suggestion of a new study from the University of California San Diego. But hold on there, overachiever parents, don't' rush just yet to sign your kids up for Chinese lessons instead of piano.

Why baboon males resort to domestic violence
Some baboon males vying for a chance to father their own offspring expedite matters in a gruesome way -- they kill infants sired by other males and attack pregnant females, causing them to miscarry, researchers report. Infanticide has been documented in other animals including baboons, lions and dolphins, but rarely feticide. The perpetrators are more prone to commit domestic violence when forced to move into a group with few fertile females, the study finds.

RIT wins NSF grant to transform physics graduate education admissions and retention
A Rochester Institute of Technology professor won funding from the National Science Foundation to develop an inclusive approach to physics graduate education admission and retention of traditionally underrepresented US citizens. Casey Miller, associate professor and director of RIT's materials science and engineering graduate program, is collaborating with the American Physical Society on a $428,022 NSF Research Traineeship award in Innovations in Graduate Education to increase diversity and physics Ph.D. completion rates among women, African Americans, Hispanic Americans and Native Americans.

Glass's off-kilter harmonies
The transport of heat in amorphous materials is largely determined by the behavior of phonons -- quasiparticles associated with the collective vibrations of atoms.  Researchers from Georgia Tech developed a new way to calculate the heat contribution of phonons using computer simulations. Using the Stampede supercomputer at the Texas Advanced Computing Center, they modeled amorphous silicon -- glass -- providing new insights into a material that is critical for energy efficiency.

Vitamin B-12, and a knockoff version, create complex market for marine vitamins
A new study shows that vitamin B-12 exists in two different, incompatible forms in the oceans. An organism thought to supply essential vitamin B-12 in the marine environment is actually churning out a knockoff version.

Green Sahara's ancient rainfall regime revealed
Rainfall patterns in the Sahara during the 6,000-year 'Green Sahara' period have been pinpointed by analyzing marine sediments. From 5,000 to 11,000 years ago, what is now the Sahara Desert had ten times the rainfall it does today and was home to hunter-gatherers who lived in the region's savannahs and wooded grasslands. The new research is the first to compile a continuous record of the region's rainfall going 25,000 years into the past.

A toolkit for transformable materials
Harvard researchers have developed a general framework to design reconfigurable metamaterials. The design strategy is scale independent, meaning it can be applied to everything from meter-scale architectures to reconfigurable nano-scale systems such as photonic crystals, waveguides and metamaterials to guide heat.
