Insects, viruses could hold key for better human teamwork in disasters

...he scientists' sights are a sub-group of their own species -- specifically, civil engineers, who historically have had a limited role in such efforts, especially those involving critical physical infrastructures. Supported by a five-year $2.37 million grant from the National Science Foundation, and suppleme...

Precise Timing Enabled Pig-to-rat Transplants To Cure Diabetes

...or immune suppression after transplanting from one species to another was such an unexpected and encouraging discovery that we wanted to find out more about why that worked and under what conditions it is possible," Hammerman says. Superficially, there appears to be relatively little difference between panc...

Mutation in clams protects against paralytic shellfish poisoning but raises human health risk

... "Since the 1960s, it's been known that different species of shellfish have different resistance to PSP toxins," says Connell. "This is the first time the source of that resistance has been shown. We now have a marker that can be used to determine if clams have this mutation. It's easy to use and could help...

Scientists identify genes responsible for 'black rot' disease in vegetables

DOE JGI launches IMG public online microbial genome data clearinghouse

...hood around a gene of unknown function in multiple species selected from the organism browser may yield clues of what its role might be in your particular species," said Andersen. "The interface is quite intuitive, which is a benefit for someone like me that does not like to read manuals." John Taylor, prof...

Unlike other mammals, newborn dolphins and orcas stay active 24/7 during first months of development

... is unique from other mammals, with calves of both species active 24 hours a day during their first month. The mother also has minimal sleep during this period, but unlike all other mammals always manages more sleep than her busy newborns. The newborns and mothers gradually increase sleep over a period of m...

Sponges as drugs

...s. For her research, De Voogd described three new species of sponges and examined the interactions of four sponge species with possible spatial competitors. She discovered that as soon as certain sponge species grow over c...

Searching the depths of the straits of Florida for disease cures

...ference in the habitat, we expect to find some new species that we haven't collected before. That's why we're going." Cay Sal is a 60-mile wide sand bank fringed with a few small islands and surrounded on all sides by the deep Straits of Florida and the swiftly flowing Florida Current, which joins with the ...

Research Reveals Functions Of Harmful Shellfish Pathogens

...ily. He also detected the enzyme in virtually all species of Vibrio tested, but not in non-Vibrio pathogens. The enzyme is capable of producing what are called vasoactive peptides, which could contribute to rapid spread of V. vulnificus in humans. A study of V. vulnificus in oysters suggests that strains vi...

Mice brains shrink during winter, impairing some learning and memory

The brains of one species of mouse actually shrink during the winter, causing the mice to have more difficulty with some types of learning, a new study found. The results showed that, during the short days of winter, white-footed mice had impaired spatial memory ?the mental ...

Roundup®highly lethal to amphibians, finds University of Pittsburgh researcher

...oles and toad tadpoles were nearly eliminated. One species of frog, spring peepers, was unaffected. "The most shocking insight coming out of this was that Roundup®, something designed to kill plants, was extremely lethal to amphibians," said Relyea, who conducted the research at Pitt's Pymatuning Laboratory...
