Researchers develop technologies to devour food pathogens

... of bacteria by analyzing how light is refracted-a unique "scatter pattern." Bhunia has shown his technology is capable of recognizing Listeria monocytogenes, a microbial pathogen that is the leading cause of food-borne illness. The pathogen has a high mortality rate-one in five-and kills about 500 people...

Ocean seep mollusks may share evolutionary history with other deep-sea creatures

...lusks owe their long evolutionary history to their unique home environment or to their status as deep-sea cr...ethane leak up through the ocean floor, creating a unique chemical environment where hardy bacteria process the sulfide and methane. Seep fluids are about the...

Teenager moves video icons just by imagination

...d a computer game have gone hands-off, thanks to a unique experiment conducted by a team of neurosurgeons, neurologists, and engineers at Washington University in St. Louis. The boy, a 14-year-old who suffers from epilepsy, is the first teenager to play a two-dimensional video game, Space Invaders, using...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

Siberian lakes burp 'time-bomb' greenhouse gas

...s by between 10 and 63 percent. Walter studied a unique type of permafrost in Siberia, called yedoma, which contains an estimated 500 gigatons of carbon, largely in the form of ancient dead plant material. "This material has been locked up in permafrost since the end of the last ice age," Walter said. "No...

First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands

...ers, large crabs, sea urchins). This expedition is unique in focusing primarily on the more cryptic small invertebrates (tiny crabs, mollusks, sea slugs, worms and more), algae, and microbes over a range of habitats at French Frigate Shoals. Although some of these smaller organisms may not be as charismati...

Scientists discover toxin that causes gastro disease

... cells in the gastrointestinal tract. "It is unique because it cuts an essential component of the cell machinery in half, therefore disabling it," he said. As well as learning how the toxin works, the scientists have also determined its three-dimensional structure, which will aid in the developme...

'Conversation stoppers' fight deadly bacterial infections

...sis. However, the authors of the study noted, the unique contribution that this Abh4-mediated route makes to the production of NAEs in vivo is yet to be determined and will require "the generation of genetic or pharmacological tools that selectively [interrupt] this pathway." "The continued pursuit of ad...

Muscle and bone from an ink-jet printer

...team has used an innovative inkjet system to print unique "bio-ink" patterns that directed adult muscle-derived stem cells from mice to differentiate into both muscle cells and bone cells. This is the first report of a system that can pattern the formation of multiple tissues from a single population of a...

Unraveling where chimp and human brains diverge

...s diverged from a common ancestor and evolved into unique species. Now UCLA scientists have identified a new way to pinpoint the genes that separate us from our closest living relative ?and make us uniquely human. The Proceedings of the National Academy of Sciences reports the study in its Nov. 13 online ...

Technology exists to keep E. coli out of food

...tem, developed by a team of Russian scientists, is unique because it produces a pH-neutral solution that won't cause deterioration or off-flavors when sprayed on food. The system is environmentally friendly; its only outputs are water and salt. Feirtag sees great potential for the system and is working to...

Geneticists discover genes that make fruit fly hybrids sterile

...s in any species that are responsible for problems unique to hybrids. Specifically, the researchers have found two genes from two fruit fly species ( Drosophila melanogaster and D. simulans ) that interfere with each other, thereby preventing the production of male offspring. The finding may eventually ...

'Trojan Horse' agent halts bone metastasis in mice

... receptors in blood vessels and in bone cells is a unique finding that could be clinically significant, not only to treating cancer but other bone disorders," he says. "In the least, this study helps us understand more about how VEGF operates inside the body and how it is involved in bone remodeling." R...

Researchers discover that sheep need retroviruses for reproduction

...pment of the placenta in sheep. Retroviruses are unique for their ability to permanently insert their genetic material into the DNA of host cells, he said. During evolution of mammals, some retroviruses infected the germline (cells of the ovary and testis that have genetic material that are passed to the...

Successful lung cancer surgery not enough to break nicotine dependence in many smokers

... of 13 percent to about 60 percent. This study was unique in that it sought to include patients believed to be highly dependent on nicotine - so it included only patients who smoked within three months of their diagnosis - and it attempted to use saliva samples as well as questionnaires to gauge whether pa...

Researchers make nanosheets that mimic protein formation

...ang of Kotov's group. The team discovered that the unique shape of the CdTe nanocrystals gave rise to a combination of forces that conspired to produce the unusual two-dimensional packing. Subsequent experiments by Kotov's group showed that if any of the forces were missing, the sheets would not form, conf...
