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...

Science Uses X-Rays To Unlock Mystery Of Picasso Paint
2013-02-07 14:27:31

Michael Harper for redOrbit.com — Your Universe Online The best way to win any decades-long debate is science, science, and more science. If, for example, you´re able to hire a team of technicians to operate a powerful X-Ray to prove your point, there´s almost no way you´ll lose. Such is the case with a long-standing debate over which type of paint Picasso used in his works. Art scholars have been arguing for many years over the theory that the cubist painter used...

Researchers are improving the performance of technologies ranging from medical CT scanners to digital cameras using a system of models to extract specific information from huge collections of data and then reconstructing images like a jigsaw puzzle. The new approach is called model-based iterative reconstruction, or MBIR. "It's more-or-less how humans solve problems by trial and error, assessing probability and discarding extraneous information," said Charles Bouman, Purdue University's...

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...

Using an innovative approach, scientists at The Scripps Research Institute (TSRI) have determined the structure of Ltn1, a recently discovered “quality-control” protein that is found in the cells of all plants, fungi and animals. Ltn1 appears to be essential for keeping cells´ protein-making machinery working smoothly. It may also be relevant to human neurodegenerative diseases, for an Ltn1 mutation in mice leads to a motor-neuron disease resembling amyotrophic lateral...

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...

Mouse Brain Analyzed Under The Electron Microscope
2012-10-23 10:16:46

What happens in the brain when we see, hear, think and remember? To be able to answer questions like this, neuroscientists need information about how the millions of neurons in the brain are connected to each other. Scientists at the Max Planck Institute for Medical Research in Heidelberg have taken a crucial step towards obtaining a complete circuit diagram of the brain of the mouse, a key model organism for the neurosciences. The research group working with Winfried Denk has developed a...

New process developed at MIT could enable better LED displays, solar cells and biosensors – and foster basic physics research. Films made of semiconductor nanocrystals – tiny crystals measuring just a few billionths of a meter across – are seen as a promising new material for a wide range of applications. Nanocrystals could be used in electronic or photonic circuits, detectors for biomolecules, or the glowing pixels on high-resolution display screens. They also hold...

redOrbit Staff & Wire Reports - Your Universe Online Researchers are one step closer to solving the mysteries of graphene, the carbon allotrope that could be the basis for the next generation of sensors, transistors, processors and more - if scientists can find a way to produce it in large quantities and mold it into the shape necessary to power future devices. One of the major problems with the material is that it is difficult to grow it into a layer that is only a single atom...

Gold-plated Fossil Cleanup
2012-05-24 07:27:54

A team from the University of Leicester has solved a long-standing problem in fossil research, and their novel approach will assist in the study of ancient specimens. Fossils are often coated with a very thin layer of gold to study the specimens under an electron microscope. The gold brings out otherwise invisible details. When the analysis is complete the fossils need to be returned to their natural state. However, the removal of the gold has always been difficult, expensive, and uses...

Word of the Day
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
