New Technique Allows Closer Look At How Radiation Damages Materials
2013-08-06 12:41:39

North Carolina State University A team of researchers led by North Carolina State University has developed a technique that provides real-time images of how magnesium changes at the atomic scale when exposed to radiation. The technique may give researchers new insights into how radiation weakens the integrity of radiation-tolerant materials, such as those used in space exploration and in nuclear energy technologies. "We used high-resolution transmission electron microscopy (HRTEM) to...

Engineers Show How To Make Cost-effective, Ultra-high-performance Microscopes
2013-07-29 14:44:20

California Institute of Technology Engineers at the California Institute of Technology (Caltech) have devised a method to convert a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available standard microscope. Such a system could greatly improve the efficiency of digital pathology, in which specialists need to review large numbers of tissue samples. By making it possible to produce robust microscopes at low cost,...

It's not reruns of "The Jetsons", but researchers working at the National Institute of Standards and Technology (NIST) have developed a new microscopy technique that uses a process similar to how an old tube television produces a picture–cathodoluminescence–to image nanoscale features. Combining the best features of optical and scanning electron microscopy, the fast, versatile, and high-resolution technique allows scientists to view surface and subsurface features potentially as...

Topspin allows scientists to get more and better nanoscale information with unprecedented...

Ultrafast High-resolution Imaging In Real Time Could Be A Reality With New Research Discovery
2013-04-19 13:15:53

University of Melbourne In work published in Nature Communications, researchers from the University of Melbourne and the ARC Centre for Excellence in Coherent Xray Science have demonstrated that ultra short durations of electron bunches generated from laser-cooled atoms can be both very cold and ultra-fast. Lead researcher Associate Professor Robert Scholten said the surprising finding was an important step towards making ultrafast high-resolution electron imaging a reality. He said...

Blowing Glass At A Nano Scale
2013-03-25 11:13:39

Ecole Polytechnique Fédérale de Lausanne EPFL researchers are using the electrical properties of a scanning electron microscope to change the size of glass capillary tubes -- Their method has already been patented as it could pave the way to many novel applications Have you ever thrown into the fire - even if you shouldn't have - an empty packet of crisps? The outcome is striking: the plastic shrivels and bends into itself, until it turns into a small crumpled...

Cloud Computing Code Speeds Processing Of Data-intensive Microscopy Data
2013-02-01 10:33:43

Salk Institute In this week's Nature Methods, Salk researchers share a how-to secret for biologists: code for Amazon Cloud that significantly reduces the time necessary to process data-intensive microscopic images. The method promises to speed research into the underlying causes of disease by making single-molecule microscopy of practical use for more laboratories. "This is an extremely cost-effective way for labs to process super-resolution images," says Hu Cang, Salk assistant...

Biological Structures Imaged In Their Natural Habitats
2012-12-20 15:47:07

Virginia Tech In situ molecular microscopy provides a gateway to imaging dynamic systems in structural biology If the key to winning battles is knowing both your enemy and yourself, then scientists are now well on their way toward becoming the Sun Tzus of medicine by taking a giant step toward a priceless advantage — the ability to see the soldiers in action on the battlefield. Investigators at the Virginia Tech Carilion Research Institute have invented a way to directly image...

Electron Beams That Possess An Inner Rotation Created
2012-11-05 13:28:11

Vienna University of Technology Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered at the Vienna University of Technology (TU Vienna). Nowadays, electron microscopes are an essential tool, especially in the field of materials science. At TU Vienna, electron beams are being created that possess an inner rotation, similarly to a tornado. These "vortex beams" cannot only...

Word of the Day
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
