3-D pictures taken inside nanocrystals

Taking 'photographs' of individual molecules in action is probably not on the list of your next summer vacation. However, an international team of scientists from Australia, England and the U.S. has found a way to get full 3-D images of the interior of nanocrystals. Their technique, known as coherent X-ray...

From biological imaging to Sudoku

Scientists are like you and me: they sometimes need to relax. This is why Veit Elser, professor at Cornell University, has applied an algorithm developed for X-ray diffraction microscopy to solve Sudoku puzzles. The difference-map algorithm, which he discovered with other chemists and physicists, will be primarily used for biological...

Shooting movies of molecules

Scientists at the U.S. Department of Energy's DOE Argonne National Laboratory have developed techniques for creating movies of biological and chemical molecules. It has been done before for crystalline structures of salt or metals, but organic molecules are more complex, and more difficult to catch. Until now, researchers had to...

Lensless camera for nanoscale imaging

Australian and U.S. scientists have developed a lensless camera which uses X-rays to view nanoscale materials and biological specimens. As says one researcher, 'there is no lens involved at all; instead, a computer uses sophisticated algorithms to reconstruct the image.' Future microscopes equipped with these lensless cameras could be used...

The secret of levitation

Several U.K. news sources are reporting today that two Scottish researchers have developed a theory to 'levitate' very small objects. According to The Scotsman, their theory involves what is known as the 'Casimir force.' By reversing the Casimir force so that it repels instead of attracts, their discovery could...

For example, they could easily help you to see if some kind of perishable food items are not good anymore because the packaging would change color. They...

Synthetic proteins better than real ones?

Researchers at the Howard Hughes Medical Institute HHMI and Yale University have built proteins which dont exist in the natural world. Theyve constructed these proteins from beta-amino acids, which are distinct from the alpha-amino acids that compose natural proteins. Their synthetic proteins are as stable as natural ones, but provide...
