Controlling the charge state of organic molecule quantum dots in a 2D nanoarray

Researchers have fabricated a self-assembled, carbon-based nanofilm where the charge state (ie, electronically neutral or positive) can be controlled at the level of individual molecules. Molecular self-assembly on a metal results in a high-density, 2D, organic quantum-dot array with electric-field-controllable charge state, with the organic molecules used as 'nano-sized building blocks' in fabrication of functional nanomaterials. Achieved densities are an order of magnitude larger than conventional inorganic systems.

Potential therapy to treat detrimental effects of marijuana

A new study using a preclinical animal model suggests that prenatal exposure to THC, the psychoactive component of cannabis, makes the brain's dopamine neurons (an integral component of the reward system) hyperactive and increases sensitivity to the behavioral effects of THC during pre-adolescence.

Quantum paradox experiment may lead to more accurate clocks and sensors

More accurate clocks and sensors may result from a recently proposed experiment, linking an Einstein-devised paradox to quantum mechanics. A physicist said the international collaboration aimed to test Einstein's twin paradox using quantum particles in a 'superposition' state.

Achieving a safe and just future for the ocean economy

much attention has been given to the growth of the 'Blue Economy' — a term which refers to the sustainable use of ocean and marine resources for economic growth, jobs, and improved livelihoods. Ocean resources are viewed as lucrative areas for increased investment, including in fisheries, aquaculture, bio-prospecting, renewable energy, oil and gas, and other businesses. Ensuring that socially equitable and sustainable development occurs should be the mandate of governments and industry, maintain an international group of researchers, led by UBC.

Fire blankets can protect buildings from wildfires

Wrapping a building in a fire-protective blanket is a viable way of protecting it against wildfires, finds the first study to scientifically assess this method of defense. Rigorous testing reveals that existing blanket technology can protect structures from a short wildfire attack, but for successful deployment against severe fires and in areas of high housing density, technological advancement of blanket materials and deployment methods, as well as multi-structure protection strategies, are needed.

Rare 'itinerant breeding' behavior revealed in California bird

Only two bird species have ever been shown to undertake what scientists call 'itinerant breeding': nesting in one area, migrating to another region, and nesting again there within the same year, to take advantage of shifting food resources. However, new research provides strong evidence of this rare behavior in a third bird — the Phainopepla, a unique bird found in the southwestern US and the northernmost member of an otherwise tropical family.
