New law for resolution allows unprecedented sharpness in fluorescence microscopy

... the textbook knowledge was that a complicated and costly electron or scanning tunneling microscope would be required. However, over the past few years, researchers from the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany, have developed with Stimulated Emission Depletion (STED) microsc...

A step toward the $1,000 personal genome using readily available lab equipment

...chnology appears to be even more accurate and less costly than a commercial DNA decoding technology reported earlier this week. The Church group's technology is based on converting a widely available and relatively inexpensive microscope with a digital camera for use in a rapid automated sequencing process...

Costly breeding programs for endangered species pay off

... conducted at Rice University bolster the case for costly and sometimes troublesome breeding programs that preserve maximum genetic variability in small populations of endangered species. Worldwide, zoos spend millions of dollars each year transporting rare animals thousands of miles in order to breed them...

Retinal scans eyed for New Mexico show cattle

...ermanent means of identification. "DNA analysis is costly and requires a complex laboratory procedure that takes time," he said. "Also, hair samples have been lost in transit." Among the show cattle, researchers found that the retinal scans proved a near-perfect animal ID technology because of its speed an...

Why we give: New study finds evidence of generosity among our early human ancestors

...thout some kind of payback, altruism can be a very costly endeavor in small-scale societies subsisting on wild foods," Gurven writes. "This study shows that people indeed share more with those who give more to them?[but] families who cannot produce much food, close kin, and nearby neighbors sometimes receiv...

Harnessing genomic research

...th their partner Arrow Therapeutics to combat this costly and dangerous livestock and human disease. The highlights of the research programme are being presented to Parliamentarians and business leaders at a reception in London on the evening of 10 November. The programme was sponsored by the Biotechnolo...

UK sperm donor crisis

...tics in recruiting donors. "It is difficult and costly to recruit sperm donors. With the change in the anonymity rules coming we saw a sharp fall in numbers and a change in the profile of the applicants, perhaps reflecting the attitudes of different groups to anonymity. There was a significant increase i...

Asleep in the deep: Model helps assess ocean-injection strategy for combating greenhouse effect

...ctually would behave, but such experiments are too costly and time consuming to carry out under a wide range of ocean conditions. However, a new theoretical model developed by University of Michigan researcher Youxue Zhang can be used to explore the fate of CO2 injected into oceans under various temperature...

Plants, too, have ways to manage freeloaders

...dividuals, so why would an individual do something costly that benefits another individual?" she said. "Such a system is also vulnerable to exploitation - one species taking advantage of another. What mechanisms could prevent this?" She and colleagues proposed several years ago that in cooperative relation...

Biologists discover new pathway into plant cells

...pathogenic fungus that causes tan spot of wheat, a costly plant disease that is found around the world, and in some places can cause crop losses ranging up to 50 percent. These fungi produce multiple toxins that attack wheat plants, reducing yields and ruining wheat used as seed. In the United States, it's ...

ASU researchers 'wire' DNA to identify mutations

...n doing this type of detection is that it is still costly and time consuming." The team's breakthrough relies on an intrinsic physical property of DNA, conductivity, or how well the molecule can carry an electrical current. Depending on the experimental conditions, DNA has been previously shown to act as b...

Sexual reproduction delays aging in a mammalian species

...has shown that sexual reproduction is biologically costly for individuals and tends to decrease lifespan rather than increase it. But a new study by Philip Dammann and Hynek Burda from the University of Duisburg-Essen shows that, in a vertebrate species, the opposite can be true as well. The authors, study...

Ocean virus identified in human blood samples

... viruses have rarely been confined to the ocean. A costly Vesivirus epidemic in hogs first was identified in 1932, and was found to be linked to uncooked fish and pork scraps fed to hogs. It's now known that that the same types of Vesiviruses ?named in part for the disease they can cause in hogs, vesicular ...

Researchers develop portable 'vein finder' for faster, more accurate injections

... But this kind of equipment is impractical and too costly for field use. "Although the use of Doppler technology isn't new, the novel aspect of our vein finder is the system's design, which makes it both portable and economical," says Peter Rogers, a professor in Georgia Tech's School of Mechanical Enginee...

U of S researchers develop new vaccine candidate against hepatitis C

...h like HIV is spread by blood-to-blood contact, is costly and ineffective in about half the patients. Researchers working in this field have a tough job, says van den Hurk. "The hepatitis C virus is always mutating. For example, one patient can be infected with a strain that spawns sub-strains with differ...

Genome changes tracked during multiple myeloma initiation, progression and treatment

...genome project, their results will serve to direct costly sequencing efforts toward those specific regions that contain genes displaying high pathogenic relevance. "This story clearly indicates that we are dealing with the tip of the iceberg when it comes to the universe of cancer genes," says Dr. DePinho. ...

Plants used to detect gas leaks, from outer space!

...tal UK methane emissions; such losses are not only costly to the gas distributors, but can contribute to global warming since methane has a global warming potential about 8 times that of CO2. When plant roots are starved of oxygen the stress caused to the plant can be quantified from the spectral quality o...

Study finds how organs monitor themselves during early development
