Scientists create 'no tears' onions |
Scientists in New Zealand and Japan have created a "tear-free" onion using biotechnology to switch off the gene behind the enzyme that makes us cry, one of the leading researchers said Friday.

Russia's S-400 anti-missile system is now deployed around |
Russia's S-400 anti-missile system is now deployed around Moscow. If it works as claimed, it is the most formidable of its kind in the world. But the very slow deployment timetable announced for it indicates a continuing lack of resources to produce it in the Russian industrial sector.

From microscopy to nanoscopy |
Layer-by-layer light microscopic nanoscale images of cells and without having to prepare thin sections? A team led by Stefan Hell and Mariano Bossi at the Max Planck Institute for Biophysical Chemistry in Göttingen is now leading the way with a technique called optical 3D far-field microscopy—with nanoscale resolution, good signal-to-noise ratio, and relatively short exposure times.

Divide-and-conquer strategy key to fast protein folding |
Researchers have found that proteins may use a divide-and-conquer strategy to fold into their native states in mere microseconds. The physical strategy, called “zipping and assembly” (ZA), can increase the speed at which supercomputers predict protein folding structures, greatly increasing scientists’ understanding of these building blocks of life.

Using a magnet to tune a magnet |
An international research team, led by scientists at the London Centre for Nanotechnology (LCN), has found a way to switch a material’s magnetic properties from ‘hard’ to ‘soft’ and back again – something which could lead to new ways of controlling electromagnetic devices.

Scientists Make Flexible, Polymer-Based Data Storage |
The future of the electronics industry is believed by many to lie in organic materials – polymers that conduct electricity. Because they are ultra lightweight, flexible, and low-cost, they may lead to a whole new class of electronic technologies. As part of this movement, scientists recently developed a polymer-based, flexible type of data storage that displays promising information-storing characteristics.
