Brazil creates buffer zone around coral reefs off Atlantic coast

...ncluding assessments of the effects of oil and gas exploration and possible oil spills that helped motivate the effort by IBAMA to get the buffer zone declared. Under the government declaration, oil and gas activities are prohibited in 75 percent of the buffer zone, and approval for such development in the othe...

First study to show how immune cells 'speak' to each other in vivo

...ses. The findings will allow further experimental exploration of immunological synaptic function during normal and pathological immune responses in vivo. The full study can be accessed at www.jem.org . WHY: The mechanism of how immunological synapses "speak" to each other in vivo has not been observed ...

Microscopic passengers to hitch ride on space shuttle

...entists evaluate the risks to astronauts on future exploration missions planned to go to the moon and Mars. "Spaceflight holds tremendous potential for the development of novel therapeutics, vaccines and diagnostics to treat, prevent and control infectious diseases," said Cheryl A. Nickerson, Ph.D., the experi...

Possible brain hormone may unlock mystery of hibernation

...rs said. "These studies may further stimulate the exploration of new techniques for cryosurgery of the heart and brain, as well as the development of hypothermia treatment that is effective for preventing brain ischemic damage." In cryosurgery, physicians use extreme cold to destroy abnormal tissue, such as can...

Biologists develop genome-wide map of miRNA-mRNA interactions

...r Comparative Functional Genomics. This allows for exploration of miRNA target predictions in the context of various functional genomic data resources ( gnetbrowse.org ). ...

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

... which were described in 2003. Recent and planned exploration of the New England Seamounts may yield new species, but most certainly will provide first records of plants or animals found in other parts of the world, such as the Mid-Atlantic Ridge or the eastern North Atlantic. We associate corals with warm t...

How sperm crack the whip

... once it enters the cell. Such studies will enable exploration of sperm machinery from tail to head ?analyzing processes ranging from tail motility to the mechanism by which the sperm head delivers its genetic payload to the egg, he said. Such research could yield insight into some male infertility, said Claph...

Potential heart benefit found in stem cells

...ghs in cardiovascular medicine. "We hope that the exploration of stem cells derived from new sources may bypass some of the debate that is preventing research progress right now," said Sharon A. Hunt, M.D., Stanford University. "The research presented here is extremely promising, and should be followed by more...

The world's deepest dinosaur finding - 2256 metres below the seabed

... core ?a long cylinder of rock drilled out from an exploration well at the Snorre offshore field. Norway's first dinosaur fossil is a Plateosaurus, a species that could be up to nine metres long and weigh up to four tons. It lived in Europe and on Greenland 210 to 195 million years ago, at the end of the Triass...

Newly identified mechanism helps explain why people of African descent are more vulnerable to TB

...l animals. "These studies began with a very basic exploration of differences in gene expression in two related human white blood cell types known to be involved in host responses to infection, and concluded by revealing a new and potentially important human mechanism for killing intracellular pathogens," said ...

ORNL leading effort to help harness power of Shewanella

This is one of six recently announced DOE projects aimed at increasing knowledge of microbes and microbial communities with potential applications in bioremediation, ethanol and hydrogen produc...

New amphibian species result from exploration, not from rule changes

... Germany, and colleagues, conclude that "Taxonomic exploration is still desperately needed to avoid misinterpretations in global conservation policy." Köhler and his coauthors reached their conclusions after examining genetic data on a Madagascan frog family, the Mantellidae, that grew from 143 to 203 species b...

Computers close in on protein structure prediction

...biology. Better models will depend on both smarter exploration strategies and more computer power. "If methods stayed where we are, we wouldn't solve the problem," Baker said. "On the other hand, we would do better with 10 times more computer time." It takes less than one minute for a protein to fold into its c...

But it’s worth investing in the plant exploration needed to find out.?/p> Because citrus readily crosses and the resulting plants can be propagated true-to-type through grafting, selective breeding efforts encouraging desirable qualities—like sweetness—have been very successful. But breeding for...
