Research opens opportunities to develop targeted drug therapy for cardiac arrhythmia
Biomedical engineers at Washington University in St. Louis have discovered that for one important channel in the heart, the membrane voltage not only causes the channel to open, but also determines the properties of the electrical signals.

How electrons split: New evidence of exotic behaviors
A study led by EPFL has shown for the first time that electrons split into electrical charge and magnetic moment in a two-dimensional model. The discovery marks a new understanding in the discovery of exotic materials such as high-temperature superconductors.

Hands on: Crafting ultrathin color coatings
Research from Harvard School of Engineering and Applied Sciences suggests that an ultra-thin layer of a metal and a semiconductor could be applied to essentially any rough or flexible material to produce a vividly colored coating. The technique, which exploits optical interference effects, could potentially be used on wearable fabrics or stretchable electronics.

Decision 'cascades' in social networks
A paper published this month in the SIAM Journal on Computing shows how people in social networks are often influenced by each other's decisions, resulting in a run of behaviors in which their choices become highly correlated, causing a cascade of decisions.

Fragile bones of modern humans result from reduced physical activity
The comparatively light bone structure of modern humans compared to early human species and other modern primates may be due to the modern abandonment of the constant physical activity that was inherent in the life of early hunter gathers, according to an international team of researchers. This knowledge may aid in prevention of osteoporosis and hip fracture in the elderly.

Modern genetics confirm ancient relationship between fins and hands
Efforts to connect the evolutionary transition from fish fins to wrist and fingers with the genetic machinery for this adaptation have fallen short because they focused on the wrong fish. Now, researchers describe the genetic machinery for autopod assembly in a non-model fish, the spotted gar.

Coral reveals long-term link between Pacific winds, global climate
New research indicates that shifts in Pacific trade winds played a key role in twentieth century climate variation and are likely again influencing global temperatures. The study, led by NCAR and the University of Arizona, uses a novel method of analyzing coral chemistry to reveal winds from a century ago.

Researchers discover new genetic anomalies in lung cancer
By analyzing the DNA and RNA of lung cancers, researchers at the University of Michigan Comprehensive Cancer Center found that patients whose tumors contained a large number of gene fusions had worse outcomes than patients with fewer gene fusions. In addition, the researchers identified several new genetic anomalies that occur in lung cancer, including in patients with a history of smoking.

A new analysis of a Martian rock that meteorite hunters plucked from an Antarctic ice field 30 years ago this month reveals a record of the planet's climate billions of years ago, back when water likely washed across its surface and any life that ever formed there might have emerged.

Instant-start computers possible with new breakthrough
If data could instead be encoded without current it would require much less energy, and make things like low-power, instant-on computing a ubiquitous reality. A team at Cornell University has made a breakthrough in that direction with a room-temperature magnetoelectric memory device. Equivalent to one computer bit, it exhibits the holy grail of next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field. Their results were published online Dec. 17 in Nature.

Team develops 'cool' new method for probing how molecules fold
Collaborating scientists from the Scripps Research Institute and the University of California San Diego have developed a powerful new system for studying how proteins and other biological molecules form and lose their natural folded structures. Using the new system, researchers can force a sample of molecules to unfold and refold by boosting and then dropping the temperature, so quickly that even some of the fastest molecular folding events can be tracked.

550-million-year-old fossils provide new clues about fossil formation
A new study from University of Missouri and Virginia Tech researchers is challenging accepted ideas about how ancient soft-bodied organisms become part of the fossil record. Findings suggest that bacteria involved in the decay of those organisms play an active role in how fossils are formed -- often in a matter of just a few tens to hundreds of years. Understanding the relationship between decay and fossilization will inform future study and help researchers interpret fossils in a new way.

Could ibuprofen be an anti-aging medicine?
Could a drug that is in most people's medicine cabinets hold the key to a longer, healthier life? New research shows that ibuprofen, a common over-the-counter remedy used to relieve pain and fever, extends the lifespan of yeast, worms and fruit flies -- given in doses comparable to those taken by humans.

'Hairclip' protein mechanism explained
A new study describes, for the first time, a fundamental mechanism regulating a protein's shape. The 'Hairclip' mechanism involves mutations acting on one side of a protein to open or close the configuration of amino acids on the other. The findings have implications for the manipulation of proteins, with potential applications in biotechnology and drug development.
