Full Titanic wreck site mapped for first time - Technology & science - Science - msnbc.com
SOUTH PORTLAND, Maine — Researchers have pieced together what's believed to be the first comprehensive map of the entire 3-by-5-mile (5-by-8-kilometer) Titanic debris field and hope it will provide new clues about what exactly happened the night 100 years ago when the superliner hit an iceberg, plunged to the bottom of the North Atlantic and became a legend. Marks on the muddy ocean bottom suggest, for instance, that the stern rotated like a helicopter blade as the ship sank, rather than plunging straight down, researchers told The Associated Press. An expedition team used sonar imaging and more than 100,000 photos taken from underwater robots to create the map, which shows where hundreds of objects and pieces of the presumed-unsinkable vessel landed after striking an iceberg, killing more than 1,500 people.

Researchers attending one of the world's major academic conferences 'are scared to death of the anti-science lobby' Most scientists, on achieving high office, keep their public remarks to the bland and reassuring. Last week Nina Fedoroff, the president of the American Association for the Advancement of Science (AAAS), broke ranks in a spectacular manner.

MacGregor Campbell, contributor Although they don't actually exist in the physical world, our most powerful tools could be mathematical equations. They underlie much of modern technology, from radio to power generation, to photo compression and electronic musical instruments. In our latest animated explainer, we look at how the wave equation, Maxwell's equations and the Fourier transform came to rule the modern world.

Child creates molecule that could be used for energy storage or explosives
I don't know about other people, but when I was a child, I was inventing things such as a musical instrument made out of a folded piece of cardboard and some rubber bands. Ten year-old Clara Lazen, however, has done something a little more noteworthy. The fifth-grader from Kansas City, Missouri, built a model of a molecule that is new to science.
MIT’s photonic crystals lead towards nuclear batteries everywhere | ExtremeTech
Researchers at MIT have developed photonic crystals that, in as little as two years, could enable the use of hydrocarbon reactors in portable electronic devices, and nuclear power sources everywhere else. Photonic crystals are optical nanostructures that are tuned to specific wavelengths of light. If you understand how semiconductors affect the motion of electrons (i.e. the bandgap only allows electrons with a certain energy level to pass through), photonic crystals are the optical equivalent.
