Highly adaptable genome in gut bacterium key to intestinal health

... fact, it can call on a larger repertoire of genes related to carbohydrate digestion than any other microbe we know of." Next, the researchers will use germ-free mice to investigate how B. theta interacts with other members of the gut ecosystem. By defining the factors that underlie the stability of the gut...

Researchers trace evolution to relatively simple genetic changes

...is clinical disease in humans. And this finding is related to the old argument whether Nature can use the same genes and create other traits in other animals." Ordinarily, "you wouldn't look at that gene and say it's an obvious candidate for dramatically changing skeletal structures in wild animals that end...

The ability tomonitor the health of small groups of cells, however, makes it possibleto detect the presence of unknown poisons as long as they affect cellmetabolism. Furthermore, by examining the impact that an unknown agenthas on different c...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...tive damage to the tissues. This damage is closely related to aging. Hence, perhaps, the many anti-oxidative creams flooding the market to combat aging. The concentration of oxygen in the air we breathe is toxic to us. Indeed, fruit flies, which have been studied closely for decades, die sooner from aging in...

Scientists discover unique microbe in California's largest lake

... as well."All three of these organisms are closely related species ofAcaryochloris, but the other two live in the Pacific and must grow onor in an animal or plant to survive in nature," Wood says. "This newmicrobe opens up a whole new range of possible habitats where oxygencould be produced by photosynthesis...

An entropy-based gene selection method for cancer classification using microarray data

...ntropy-based method is proposed that selects genes related to the different cancer classes while at the same time reducing the redundancy among the genes. Results The present study identifies a subset of features by maximizing the relevance and minimizing the redundancy of the selected genes. A merit calle...

DNA Recombination and Repair—A New Twist to RecA Function

...ecular motors harness the energy of ATP (or GTP, a related energy currency) and transform it into mechanical force. Well-known examples of motors include myosin and dynein, proteins that use ATP to ferry intracellular cargo along fibers made of actin or tubulin proteins. The ATP-dependent assembly of actin o...

NC State scientist finds soft tissue in T. rex bones

... data indicates that living birds are more closely related to dinosaurs than any other group, Schweitzer compared the findings from the T. rex with structures found in modern-day ostriches. In both samples, transparent branching blood vessels were present, and many of the small microstructures present in the...

The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

Although the main focus of the second phase of the PSI will be on solving protein structures, Norvell said there will be continued development of new technology: “As we reach for higher-hanging fruit ?protein structures that ar...

New research indicates a 'troubled' greenhouse is brewing

... spread within the profile of carbonate nodules is related to the difference in precipitation between the driest and wettest month. Retallack uses this feature in ancient soils to reinterpret past climates. Retallack is an authority on paleosols (ancient soils) and is writing a book about healing the global...
