Robin Thicke may have sung "Blurred Lines" and appeared in a teenage fantasy video with a lot of naked women, but when a photo was revealed of him in a suggestive situation with another woman, he found that the line was actually not all that blurry to his wife.(1)

What changed? She had been fine with his canoodling before. He has no idea and men meeting women across the nation are just as confused about where their blurred lines are. 

Linguists have conducted what they call an evolutionary analysis to the relationship between North American and Central Siberian languages and say the results indicate that people moved out from the Bering Land Bridge, with some migrating back to central Asia and others into North America.

A 70 million year old fossil found in the Late Cretaceous sediments of Alaska reveals a new small tyrannosaur named Nanuqsaurus hoglundi.  

The team of Francesca Ferlaino, Institute for Experimental Physics of the University of Innsbruck, Austria, has experimentally shown chaotic behavior of particles in a quantum gas. "For the first time we have been able to observe quantum chaos in the scattering behavior of ultracold atoms," says an excited Ferlaino. The physicists used random matrix theory to confirm their results, thus asserting the universal character of this statistical theory. Nobel laureate Eugene Wigner formulated random matrix theory to describe complex systems in the 1950s. Although interactions between neutrons with atomic nuclei were not well-known then, Wigner was able to reliably predict properties of complex spectra by using random matrices.

Can you catch a mood from someone online? Most people would answer 'yes', because lots of comments on the Internet enrage them.

A political science paper says they can confirm it.

After a 30-year search, scientists have uncovered how an enzyme critical to plants' rapid immune response against microbes is activated.

"The insights will open up new ways to improve disease resistance and stress tolerance in plants," says Professor Cyril Zipfel of The Sainsbury Laboratory in Norwich.

The enzyme, the NAPDH oxidase RBOHD, triggers a rapid generation of signalling molecules derived from oxygen that are believed to be detrimental to microbial growth. The newly-discovered way this enzyme is activated, by a protein (called BIK1) fills a gap in how plants perceive a threat and how signals are activated to trigger an immune response.

Washington, DC— John F. Strang, PsyD, a pediatric neuropsychologist at Children's National Health System, and colleagues, found that children with autism spectrum disorders (ASD) or attention deficit hyperactivity disorder (ADHD) were more likely to exhibit gender variance, the wish to be the other gender, than children with no neurodevelopmental disorder, or a medical neurodevelopmental disorder such as epilepsy or neurofibromatosis.

Will one-atom-thick layers of molybdenum disulfide, a compound that occurs naturally in rocks, prove to be better than graphene for electronic applications? There are many signs that might prove to be the case. But physicists from the Faculty of Physics at the University of Warsaw have shown that the nature of the phenomena occurring in layered materials are still ill-understood and require further research.

Fabrizio Tamburini, the Italian researcher who has discovered an innovative way to multiply the transmission of electromagnetic signals by exploiting the vorticity of photons, has received last Saturday the "San Valentino prize" at Palazzo Gazzolli in Terni, Italy.

The annual prize was founded in 1969 by Agostino Pensa and is meant to recognize the professional devotion of scientist and artists to their work. In the past years the prize has gone, among others, to several distinguished physicists: Ugo Amaldi, Carlo Rubbia, Emilio Segre', Tullio Regge.
