Study shows humans have ability to track odors, much like bloodhounds

...t?" he wrote, only partly tongue-in-cheek. "In the traditional world of the truffle forests, the dog (or pig) is king. The evidence presented here suggests that humans are every bit as well equipped to carry out the search." Forty years ago, Nobel Prize laureate Georg von Bekesy claimed that humans had the abil...

First production of human monoclonal antibodies in chicken eggs published in Nature Biotechnology

"Furthermore," Dr. Kay continued, "unlike other transgenic animal systems, the time from antibody identification to production in eggs can be as short as 8 months versus 18 months to 3 years for goats or cattle. The eg...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...ctronic devices. Manufacturing nanowires from more traditional materials such as metals, silica, or carbon is difficult and expensive. However, it is easy to grow billions of Geobacter cells in the laboratory and harvest the microbial nanowires that they produce. Furthermore, by altering the DNA sequence of the ...

Breakthrough: Scientists create world's tiniest organic particles

...independent of one another."This is in contrast to traditional imprint lithography with silicon, glass or quartz molds where it is difficult to eliminate this residual material between objects," DeSimone said. Particles injected into the body can be designed to be biodegradable, he said. Some are made from the ...

Researchers develop new method for facile identification of proteins in bacterial cells

...ins in whole cell extracts of microorganisms using traditional peptide mass fingerprinting (PMF). The key to the new method, according to the researchers, is a "shortcut" for preparing samples that makes PMF faster and more economical. By reducing the cost of protein identification, they believe PMF can become a...

His research includes a special focus on sleep apnea which can set the stage for high blood pressure. Halliwill, who also studies ...

Microscopic brain imaging in the palm of your hand

...ile two-photon microscopy offers an alternative to traditional one-photon fluorescence microscopy, it still only penetrates brain tissue down to about 500-600 microns ?barely scratching the surface. To get at the deep structures, the Stanford researchers turned to microendoscopy, tiny, minimally invasive optical...

New technique rapidly detects illness-causing bacteria

.... The entire process takes only 35 minutes, while traditional gene amplification techniques may take many hours. Promising early results suggest the sensitive method could detect fewer than 100 cells of a pathogen in just half an hour. Nugen's software also compares a target site with sequences from other org...
