Stressed out: Research sheds new light on why rechargeable batteries fail
Lithium ions traveling through a zinc antimonide anode cause local stress and phase transitions, a process dubbed atomic shuffling. These changes may help explain why most anodes made of layered materials eventually fail.

Public feels more negative toward drug addicts than mentally ill
People are significantly more likely to have negative attitudes toward those suffering from drug addiction than those with mental illness, and don't support insurance, housing and employment policies that benefit those dependent on drugs, new Johns Hopkins Bloomberg School of Public Health research suggests.

Nanoparticles accumulate quickly in wetland sediment
Using mesocosms that closely approximate wetland ecosystems, researchers show carbon nanotubes accumulate quickly in sediments -- a tendency that could indirectly damage aquatic food chains by piggybacking harmful molecules.

Evolving plumbing system beneath Greenland slows ice sheet as summer progresses
A team led by scientists at the University of Texas at Austin's Institute for Geophysics has for the first time directly observed multiple parts of Greenland's subglacial plumbing system and how that system evolves each summer to slow down the ice sheet's movement toward the sea. These new observations could be important in accurately modeling Greenland's future response to climate change.

Gut bacteria are protected by host during illness
To protect their gut microbes during illness, sick mice produce specialized sugars in the gut that feed their microbiota and maintain a healthy microbial balance. This protective mechanism also appears to help resist or tolerate additional harmful pathogens, and its disruption may play a role in human diseases such as Crohn's disease, report scientists from the University of Chicago in Nature on Oct 1.

Genetic secrets of the monarch butterfly revealed
Sequencing the genomes of monarch butterflies from around the world, a team of scientists has made surprising new insights into the monarch's genetics. They identified a single gene that appears central to migration -- a behavior generally regarded as complex -- and another that controls pigmentation. The researchers also shed light on the evolutionary origins of the monarch. They report their findings Oct. 1 in Nature.

Gene doubling shapes the world: Instant speciation, biodiversity, and the root of our existence
In their review, Soltis and colleagues emphasize that polyploidy and the important role it has played, especially in plant evolution, would not have gained the recognition it deserves would it not have been for its staunch proponent, G. L. Stebbins. In the mid-20th century Stebbins synthesized what was known at that time about polyploidy, classifying different types of ploidy, discussing ancient polyploidy events, and investigating hybridizing species and polyploid derivatives.

Alcohol makes smiles more 'contagious,' but only for men
Consuming an alcoholic beverage may make men more responsive to the smiles of others in their social group, according to new research in Clinical Psychological Science, a journal of the Association for Psychological Science. The findings suggest that, for men, alcohol increases sensitivity to rewarding social behaviors like smiling, and may shed light on risk factors that contribute to problem drinking among men.

Deceptive-looking vortex line in superfluid led to twice-mistaken identity
So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of solitons -- exotic, solitary waves. Instead, they explain, the result was due to more pedestrian, whirlpool-like structures in the fluid. They published their explanation in the Sept. 19 issue of Physical Review Letters.

Adding uncertainty to improve mathematical models
Mathematicians from Brown University have introduced a new element of uncertainty into an equation used to describe the behavior of fluid flows. While being as certain as possible is generally the stock and trade of mathematics, the researchers hope this new formulation might ultimately lead to mathematical models that better reflect the inherent uncertainties of the natural world.

How things coil
Columbia Engineering and Massachusetts Institute of Technology researchers have combined computer simulations designed for Hollywood with precision model experiments to examine the mechanics of coiling, discovering in particular that the natural curvature of the rod dramatically affects the coiling process. Their study, which bridges engineering mechanics and computer graphics, impacts a variety of engineering applications, from the fabrication of nanotube serpentines to the laying of submarine cables and pipelines.

Viral infection might just be a phase... transition
Many double-stranded DNA viruses infect cells by ejecting their genetic information into a host cell. But how does the rigid DNA packaged inside a virus flow into a cell? In two separate studies, Carnegie Mellon biophysicist Alex Evilevitch has shown that in viruses that infect both bacteria and humans, a phase transition at the temperature of infection allows the DNA to change from a rigid crystalline structure into a fluid-like structure that facilitates infection.

Penn team studies nanocrystals by passing them through tiny pores
An interdisciplinary team of University of Pennsylvania researchers has now applied a cutting-edge technique for rapid gene sequencing toward measuring other nanoscopic structures. By passing nanoscale spheres and rods through a tiny hole in a membrane, the team was able to measure the electrical properties of those structures' surfaces. Their findings suggest new ways of using this technique, known as 'nanopore translocation,' to analyze objects at the smallest scale.
