Data from the ESA/NASA spacecraft SOHO shows clearly that powerful starquakes ripple around the Sun in the wake of mighty solar flares that explode above its surface. The observations give solar physicists new insight into a long-running solar mystery and may even provide a way of studying other stars.

The outermost quarter of the Sun’s interior is a constantly churning maelstrom of hot gas. Turbulence in this region causes ripples that criss-cross the solar surface, making it heave up and down in a patchwork pattern of peaks and troughs.

Researchers at the Department of Energy's Pacific Northwest National Laboratory found that the restless movement of oxygen atoms heals radiation-induced damage in the engineered ceramic yttria-stabilized zirconia.

This may lead to development of radiation-resistant materials for nuclear power plants and waste storage.

Scientists Ram Devanathan and Bill Weber modeled how well that ceramic and other materials stand up to radiation. "If you want a material to withstand radiation over millennia, you can't expect it to just sit there and take it. There must be a mechanism for self-healing," said Devanathan.

Your contact lenses of the future could be completely biodegradable. A soft contact lens is a hydrogel - a solid, gelatinous mass consisting of water incorporated in a polymer network.

Now Berkeley researchers have developed a technique for the formation of hybrid materials from synthetic polymers and proteins, fusing the biological functions of proteins with the processing properties of plastics.

Aaron P. Esser-Kahn and Matthew B. Francis say they have successfully synthesized a green-fluorescing biodegradable gel that responds to changes in pH value and temperature. These polymer-protein hybrid materials can also be used in sensors, nanomachine parts, or drug-delivery systems.

Increased carbon dioxide in the Earth's atmosphere is causing microscopic ocean plants to produce greater amounts of calcium carbonate (chalk) - with potentially wide ranging implications for predicting the cycling of carbon in the oceans and climate modelling.

That is the conclusion of an international team of scientists led by investigators based at the UK's National Oceanography Centre, Southampton and the University of Oxford, published in Science, on 18 April 2008.

Co lead-author, Dr M Debora Iglesias-Rodriguez, of the University of Southampton's School of Ocean and Earth Science at the National Oceanography Centre, Southampton said:

A connection between vitamin D level and the risk of developing breast cancer has been implicated for a long time, but its clinical relevance had not yet been proven.

Sascha Abbas and colleagues from the working group headed by Dr. Jenny Chang-Claude at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ), collaborating with researchers of the University Hospitals in Hamburg-Eppendorf, have now obtained clear results: While previous studies had concentrated chiefly on nutritional vitamin D, the researchers have now investigated the complete vitamin D status. To this end, they studied 25-hydroxyvitamin D (25(OH)D) as a marker for both endogenous vitamin D and vitamin D from food intake.

When a hypothetical, quantum-scale balloon is popped in a vacuum, do the particles inside spread out as predicted by classical mechanics or do something else, since matter at the infinitesimally small quantum scale is both a wave and a particle, and its location cannot be fixed precisely because measurement alters the system?

The question is deceptively complex, since quantum particles do not look or act like air molecules in a real balloon. Theoretical physicists at the University of Southern California have an answer Heisenberg would be proud of.

Quantum-scale chaos exists … sort of.

Supporters of legalizing euthanasia and those who wish to develop better palliative care services can help rather than combat each other, according to a study published on bmj.com.

Palliative care concerns itself with the relief of the pain, symptoms and stress of serious illness while improving the quality of life for patients and their families. Euthanasia is where a third party causes the death of a patient. But the traditional view that palliative care and euthanasia are two alternative and antagonistic causes is not necessarily the case, say researchers.

Jan Berheim and colleagues from the End-of-Life Care Research Group of the Vrije Universiteit Brussel, reviewed historical, regulatory and epidemiological evidence from Belgium, which was the second country to legalise euthanasia in 2002, and has some of the best developed provisions for palliative care, third only to Iceland and the UK.

In recent decades, manufacturers have added more and more components onto integrated circuits. As a result, the number of transistors and the power of these circuits have roughly doubled every two years. This has become known as Moore’s Law.

But the ability to easily add more components is now noticeably decreasing and further miniaturization of electronics will experience a fundamental challenge in the next 10 years.

There's hope on the horizon. Researchers at The University of Manchesterhave used the world’s thinnest material to create the world’s smallest transistor, one atom thick and ten atoms wide. How small is that? You could fit 25 million of them in an inch.

An exhibit developed by the Museum of Science, Boston, in collaboration with Lucasfilm, Ltd. explores the possibility that some of the robots, vehicles and devices of the Star Wars films are closer to reality than one might think.

The exhibition, at the Franklin Institute in Philadelphia, Pa., through May 4, discusses landspeeders and robots as engineering design challenges and highlights how researchers are currently pursuing similar technologies.

"We were surprised and delighted when we were developing the exhibit, to discover that many scientists working today were inspired by the fantasy technologies in the Star Wars movies," said Lawrence Bell, senior vice president at the Museum of Science and the lead investigator for the project. "We developed the exhibit with the goal of continuing that inspiration for the kids who will be the next set of future scientists."

Internet sites love to pounce on the latest ridiculous story, the more outrageous the better. The silliest thing this week propagated by press release aggregators and people who don't check facts was that there was a 1 in 450 chance that the Apophis asteroid will collide with Earth after the German newspaper Potsdamer Neuerster Nachrichten reported on Tuesday that student Nico Marquardt was right and NASA was wrong.

NASA, used to being the target of fringe conspiracy theorists who will believe anything they want to believe, issued the following statement in response:
