Evidence of 600-million-year old fungi-algae symbiosis discovered in marine fossils

..."). Yuan, Xiao, and their collaborators have been exploring the Doushantuo Formation in South China for a decade and have co-authored numerous reports of fossil discoveries, including algae and animal embryos. Taylor, a member of the National Academy of Sciences, is a paleobotanist who has reported on fossil ...

Scientists use manufacturing methods to reconstruct mastodon

... events, aimed at both adult and family audiences, exploring the theme, "Mastodons and the Ice Age." A schedule of events is available at http://www.exhibits.lsa.umich.edu/New/Events/. The public can help support the new exhibit through a "buy-a-bone" program. Information on bone sponsorships is available at h...

Chemists synthesize molecule that helps body battle cancers, malaria

...s and vaccines. Gin and his collaborators are now exploring ways to improve the molecule. By investigating structure activity relationships, they want to strip away nonessential structures, leaving a simpler and more potent core. "One frequent problem encountered with vaccines is ensuring that the vaccine is...

DOE JGI launches IMG public online microbial genome data clearinghouse

...essential processes of living systems. Andersen is exploring the potential of a particular microbe, Caulobacter crescentus, for heavy-metal remediation in wastewater. "I have found the IMG system very useful in identifying potential functions for hypothetical genes that we find upregulated in Caulobacter cres...

Bee mites suppress bee immunity, open door for viruses and bacteria

..., but because it can be used as a model system for exploring what happens to viruses in animal or human populations," says Cox-Foster. "If we view the colony as a city, then we have a variety of infection modes ?queen to eggs, workers to food supply, bee to bee, and parasite to bee." ...

Stanford gut check shows diversity of intestinal ecosystem

... Medicine who have embarked on the early stages of exploring the intestinal ecosystem. Using molecular techniques that detect all known types of microbes and borrowing statistical techniques from field ecology and population genetics, Paul Eckburg, MD, a postdoctoral scholar in infectious diseases and geograp...

Birds brains reveal source of songs

...lman. "We said, this young bird is being creative, exploring many different sounds through trial and error. We hypothesized that the AFP is the source of this creativity, generating the variations, rather than comparing them." To test this theory, Fee's team studied finches that were just old enough to begin ...

Alaskan puzzles, monitoring provide insight about North Pacific salmon runs

...shery Sciences. Another high research priority is exploring harvest strategies that provide better economic benefit. Alaska fishermen have been hurt by competition from farmed fish so that much of the fleet is no longer economically viable, Hilborn says. Last year only 1,200 of the 2,000 licensed boats even b...

Flocking together: Study shows how animal groups find their way

...derwater vehicles. "Say you had a group of robots exploring a planet or the ocean, and each individual robot was moving around collecting information locally," he said. "By returning to the group and following the type of algorithm we propose, they could select collectively the direction associated with the b...

Probing the promise and perils of nanoparticles

...fects of nanoparticles. Now, the research group is exploring their interactions with living cells. "Just because we see hole formation in the model system doesn't mean that it really happens in the cell," said Banaszak Holl. But early results of experiments with living cells suggest that the same types of nan...

UCLA launches $20 million stem cell institute to investigate HIV, cancer and neurological disorders

...ch in three areas: * HIV: UCLA scientists are exploring how the AIDS virus blocks stem cell function, as well as stem cell approaches to combating HIV disease. One potential therapeutic example includes inserting antiviral genes into blood-forming stem cells and reintroducing them into the body. As these ...

Children's taste sensitivity and food choices influenced by taste gene

...es and extends Monell's long-term research program exploring development of taste and flavor preferences during childhood, a critical time for learning about food. Mennella comments, "Our previous studies focused on how early experience influences preferences for foods and flavors. Now, we have a tool to look ...

Sequencing of marine bacterium will help study of cell communication

.... The genome sequence has allowed Stevens to begin exploring the connection between quorum sensing and other global regulatory networks through a combination of comparative genomics and experimental molecular biology. Other researchers are focusing on the relationship between the bacterium and its animal host...

Falling ants glide back to trunk to avoid dangers of forest floor

... added Kaspari. "Steve, Robert and I right now are exploring how pervasive such directed descent might be ?we are, in fact, finding it in a variety of wingless arthropods that glide in using a variety of techniques. Plummeting to the earth may be the exception, not the rule." Yanoviak is in Iquitos to explore...

Scientists reveal molecular secrets of the malaria parasite

...se: * The study takes an"evolutionary approach" to exploring how the Plasmodium genome hasevolved. By comparing four sequenced genomes (the human malaria P.falciparum and the rodent malarias P. yoelii, P. chabaudi and P.berghei), the scientists found that the major differences between themalarial species are f...

Live Recombinant Adenovirus Vaccine Technique Explored

...ohns Hopkins Bloomberg School of Public Health are exploring ways to develop new vaccines for a variety of illnesses using genetically modified adenoviruses, a common cause of respiratory infections. Oral adenovirus vaccines have long been proven to be safe and effective. The researchers believe their process ...

Scientists seek answers on what activates deadly anthrax spores

...cis, have been determined. The group also will be exploring the three-dimensional structures and the functions of the proteins involved. State-of-the-art facilities at the Center for Structural Biology will be used to determine how genetic information in the anthrax chromosome translates into a vast array of ...

Fox Chase Cancer Center scientists identify immune-system mutation

...ent" or HD mice, they are proving to be useful for exploring the pathways of lymphocyte development, according to Kappes. Helper T cells, so called because they arise from the thymus gland, are essential for combating intracellular viral and bacterial infections (cell-mediated immunity) and also for helping o...
