Personality clue to ’wind turbine syndrome’
Public concern about new technology infrastructure like mobile phone masts has been shown to trigger reports of ill health.. and recently even the new 'green' technology of wind turbines has been blamed for medically unexplained non-specific symptoms. But now, for the first time, a study by psychologists, engineers and built environment experts at The University of Nottingham , has found no link between the 'measured' level of noise from small and micro wind turbines and reports of ill health.

Songbirds’ brains coordinate singing with intricate timing, study shows
As a bird sings, some neurons in its brain prepare to make the next sounds while others are synchronized with the current notes—a coordination of physical actions and brain activity that is needed to produce complex movements, new research at the University of Chicago shows. In an article in the current issue of Nature , neuroscientist Daniel Margoliash and colleagues show, for the first time, how the brain is organized to govern skilled performance—a finding that may lead to new ways of understanding human speech production.

In probing mysteries of glass, researchers find a key to toughness
Glass doesn't have to be brittle. In a paper published online Feb. 26 , a Yale University team and collaborators propose a way of predicting whether a given glass will be brittle or ductile - a desirable property typically associated with metals like steel or aluminum - and assert that any glass could have either quality.

Researchers develop new method of powering tiny devices
FINDINGS: Electromagnetic devices, from power drills to smart-phones, require an electric current to create the magnetic fields that allow them to function. But with smaller devices, efficiently delivering a current to create magnetic fields becomes more difficult. In a discovery that could lead to big changes in storing digital information and powering motors in small hand-held devices, researchers at UCLA have developed a method for switching tiny magnetic fields on and off with an electric field — a sharp departure from the traditional approach of running a current through a wire.

Mating swarm study offers new way to view flocks, schools, crowds
The adulthood of a midge fly is decidedly brief - about three days. But a new study of its mating swarm may yield lasting benefits for analyses of bird flocks, fish schools, human crowds and other forms of collective animal motion. "This is a field where there's been almost no quantitative data," said Nicholas T. Ouellette of the Yale School of Engineering & Applied Science, principal investigator of the research , published Jan.

" The results of a study published today (7 January) suggest that microbes 'feel' their way along a solid surface, much as a blindfolded person would move near a wall. Using high-speed microscopic imaging, University of Cambridge researchers have found that sperm cells accumulate at surfaces and algae move away from them as a result of between the surface and the cells' flagella or cilia - the hair-like appendages that propel cells through their fluid environment.

Synchronization phenomena are everywhere in the physical world - from circadian rhythms to side-by-side pendulum clocks coupled mechanically through vibrations in the wall. Researchers have now demonstrated synchronization at the nanoscale, using only light, not mechanics. Two tiny mechanical oscillators, suspended just nanometers apart, can talk to each other and synchronize by means of nothing but light, according to new research published Dec.

Inspiration from a porcupine’s quills
Understanding the mechanisms behind quill penetration and extraction could help engineers design better medical devices. Anyone unfortunate enough to encounter a porcupine's quills knows that once they go in, they are extremely difficult to remove. Researchers at MIT and Brigham and Women's Hospital now hope to exploit the porcupine quill's unique properties to develop new types of adhesives, needles and other medical devices.

South American cricket ears shown to rival human hearing
Scientists studying a species of South American bush cricket with some of the smallest ears known have discovered it has hearing so sophisticated that it rivals our own. The study is the first to identify hearing organs in an insect that are evolutionary convergent to those of mammals. The HFSP and BBSRC -funded research, led by the scientists at the University of Bristol, show how the bush cricket's ( Copiphora Gorgonensis ) auditory system has evolved over millions of years to develop auditory mechanisms strikingly similar to those of humans, but using an entirely different machinery.
