The name has been around for four decades, but only now is a recognizable photonics community emerging in Europe. A European study has documented a fast-growing sector of more than 2100 companies and 700 research laboratories.In 2005, Europe’s photonics sector earned €43.5 billion and was growing at 12% a year. It employed 246,000 people, accounted for 19% of world production and was already bigger than the semiconductor sector.  Yet, at the same time, the industry was hardly recognized in Europe.

A doctoral thesis carried out at the University of Granada has proved that patients with serious anxiety disorders (panic disorder with and without agoraphobia, social anxiety disorder or generalized anxiety disorder) think they suffer more physiological (palpitations, sweating, irregular breathing, shaking of the hands and muscular tension …) than they really have. In other words, although many patients with anxiety disorders have orally reported very intense physiological symptoms in surveys and questionaires, they are hyporeactive when real measures of such symptoms are taken through physiological tests.

A new study by sociologists at the University of Maryland concludes that unhappy people watch more TV, while people who describe themselves as very happy spend more time reading and socializing. The study appears in the December issue of the journal “Social Indicators Research.”Analyzing 30-years worth of national data from time-use studies and a continuing series of social attitude surveys, the Maryland researchers report that spending time watching television may contribute to viewers’ happiness in the moment, with less positive effects in the long run.

A University of Michigan professor has created 3-D portraits of the president-elect that are smaller than a grain of salt. He calls them "nanobamas."John Hart, an assistant professor in the Department of Mechanical Engineering, made the mini-Barack Obama 'Nanobama' likenesses with his colleagues to raise awareness of nanotechnology and science.   Plus, Obama flowed much nicer with 'nano' than  McCain would have.   And Hart voted for Obama, not that you didn't think so already.Each one contains about 150 million carbon nanotubes stacked vertically like trees in a forest. A carbon nanotube is an extraordinarily strong hollow cylinder about 1/50,000th the width of a human hair. 

Scientists in Madagascar, at the American Museum of Natural History in New York and the Vienna Natural History Museum and at the University of Massachusetts Amherst now have a nearly complete skeleton of a rare species of extinct lemur to study thanks to a century-long discovery and reconstruction effort. Laurie R. Godfrey, professor of anthropology at UMass Amherst and lemur expert, played a key role in the process in which contemporary researchers were able to match newly found bones with those discovered in a cave in Madagascar in 1899 to construct much of the skeleton of a rare species of extinct lemur.“It’s remarkable that we were able to reunite bits of the original skeleton,” Godfrey says. “This is a very big gift to science from many people.”

An article published electronically in the scientific journal Acta Paediatrica describes how heart rate and sleep in boys are affected by violent video games. Researchers from Stockholm University, Uppsala University and Karolinska Institutet in Sweden have worked together with this study.

A recently discovered female pelvis is changing minds about the head size of an ancient human ancestor, Homo erectus, and consequently revising notions about how smart they may have been. The Pleistocene adult female Homo erectus pelvis was from the Busidima Formation of Gona, Afar, Ethiopia., not far from the site that yielded the 3.2 million year old remains of the famed Australopithecus afarensi "Lucy," and the pelvis indicates that Homo erectus, which lived in Africa roughly 2 million years ago, had a larger birth canal than originally suspected and could have given birth to babies with bigger brains.

An unusual microorganism discovered in the open ocean may force scientists to rethink their understanding of how carbon and nitrogen cycle through ocean ecosystems.A research team led by Jonathan Zehr, a marine scientist at the University of California, Santa Cruz, characterized the new microbe by analyzing its genetic material, even though researchers have not been able to grow it in the laboratory.  Zehr said the newly described organism seems to be an atypical member of the cyanobacteria, a group of photosynthetic bacteria formerly known as blue-green algae.

Astronomers have taken snapshots of a multi-planet solar system much like ours orbiting another star, for the first time.The new solar system orbits a dusty young star named HR 8799, which is 140 light years away and about 1.5 times the size of our sun. Three planets, roughly 10, 10 and 7 times the mass of Jupiter, orbit the star. The size of the planets decreases with distance from the parent star, much like the giant planets do in our system.And there may be more planets out there, but scientists say they just haven't seen them yet.

It has all the hallmarks of a Cretaceous melodrama. A dinosaur sits on her nest of a dozen eggs on a sandy river beach. Water levels rise, and the mother is faced with a dilemma: Stay or abandon her unhatched offspring to the flood and scramble to safety?Seventy-seven million years later, scientific detective work conducted by University of Calgary and Royal Tyrrell Museum researchers used this unique fossil nest and eggs to learn more about how nest building, brooding and eggs evolved. But there is a big unresolved question: Who was the egg-layer?

Scientists may have overcome a major hurdle to calculating how much carbon dioxide (CO2) is absorbed and released by plants, vital information for understanding how the biosphere responds to stress and for determining the amount of carbon that can be safely emitted by human activities. The problem is that ecosystems simultaneously take up and release CO2. The key finding is that the compound carbonyl sulfide, which plants consume in tandem with CO2, can be used to quantify gas flow into the plants during photosynthesis. The research is published in the November 14, issue of Science. 

Evolution isn't just for living organisms. Scientists at the Carnegie Institution have found that the mineral kingdom co-evolved with life, and that up to two thirds of the more than 4,000 known types of minerals on Earth can be directly or indirectly linked to biological activity. The finding, published in American Mineralogist*, could aid scientists in the search for life on other planets.
