Scientists discover new life in the Antarctic deep sea

...al slope rise and changing water depths to build a picture of this little known region of the ocean. They found over 700 new species....

Executable biology -- Computer science sheds light on animal development

...Traditional biological models give a fairly static picture of cellular processes, and this limits understandi...rmal methods of computer science to translate this picture into a dynamic representation that can capture time-dependent processes. Results from the model can ...

Imaging pinpoints brain regions that 'see the future'

...iencing such an event in their future life; or, to picture a famous celebrity -- specifically former U.S. President Bill Clinton -- participating in such an event. The "Clinton-Imagine" task was introduced to help researchers establish a baseline level of brain activity for a cognitive event that was in m...

How trees manage water in arid environments

...ated conditions where scientists can get a clearer picture of what is happening to the water that so many people depend on. In a desert region, such forests are found only at the tops of mountains because only there does precipitation exceed evaporation enough for forest vegetation to survive. Understandi...

Technology reveals 'lock and key' proteins behind diseases

...e a puzzle. Hopefully soon we will have a complete picture of how many other diseases such as breast cancer, heart diseases, arthritis and schizophrenia are caused by mutations in various human membrane proteins." ...

Microbes start immune response by sneaking inside cells

...mentary, adds important new details to an emerging picture of how the body recognizes invading bacteria and responds. The work of the U-M team and researchers elsewhere ?now taking place in laboratory animal studies ?offers a different way of thinking about how best to design future human vaccines, as well a...

Iowa State University botanists identify new species of North American bamboo

... other characteristics. "We want to get the big picture of how all the temperate bamboos are related to each other. That means taking inventory of what exists, then comparing notes," Clark said. They already know that the closest relatives of native North American bamboos are not in Central or South A...

Scientists use nanoparticle to discover disease-causing proteins

...re collected, researchers can't obtain an accurate picture of biochemical mechanisms related to illnesses such as cancer and heart disease. Tao and his research team used dendrimers because they can pass through cell walls efficiently with little disturbance to the cells and then label specific proteins w...

Wheat can fatally starve insect predators

...eat genes, we're starting to put together a bigger picture of how Hessian fly-wheat interactions trigger resistance in the plant," Williams said. "We think that some of this has to do with the plant producing enough lectin that it just becomes so unpalatable that the insects can't feed and they starve to dea...

New findings blow a decade of assumptions out of the water

...Wrong Places." It's important to have a global picture of where nitrogen fixation is occurring ?that is where nitrogen gas is being converted into substances like nitrate that are usable by life ?in order to understand the environmental controls on nitrogen fixation and its likely response to climate cha...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...ns simultaneously let the researchers see the big picture of immune response, avoiding the contradictory results often produced by studies that focus on only a single biochemical pathway. To better understand their results, the investigators plugged their data into the Ingenuity Systems “pathways analys...

Scientists unveil piece of HIV protein that may be key to AIDS vaccine development

...es of Health (NIH), have generated an atomic-level picture of a key portion of an HIV surface protein as it l... and his colleagues provides us with a long-sought picture of the precise interaction between the HIV gp120 surface protein and this neutralizing antibody," sa...

Researchers find 6,000-year-old fossil evidence

...his discovery enables researchers to gain a better picture of ancient diets. By analyzing the grains on cooking tools, they were able to determine that people used the same grinding stones to grind corn, chili peppers and a root crop called manioc, and they probably combined these ingredients to make soups, ...

Global 'sunscreen' has likely thinned, report NASA scientists

...lly gives us an important missing piece of the big picture of the forces at work on climate." The study uses the longest uninterrupted satellite record of aerosols in the lower atmosphere, a unique set of global estimates funded by NASA. Scientists at GISS created the Global Aerosol Climatology Project by...

Walking molecule now carries packages

...scope in Bartels's laboratory that gives a precise picture of individual molecules. Experiments took place on a highly polished copper surface, cleaned so that only the desired molecules were present on it. An individual anthraquinone molecule appears in Bartels' microscope as an almost rectangular feature w...

Bacteria research offers hope for new vaccine against meningococci

...ow. At the same time, the system provides a clear picture of the process of infection. “With these findings as tools, we can continue to study the course of the disease and test vaccines on living organisms. Moreover we will be able to find new strategies for improving the prognoses for those who are af...

Turtles are loyal in feeding as well as in breeding

...me sites, but these findings give us a much better picture of the behaviour of adult turtles at sea, where they spend the majority of their life cycle.' Scientists have long known that marine turtles return to the same breeding sites each year, but did not know until now that they also revisited foraging ...

A first glimpse of the influenza replication machine

...u," says Cusack, "but this will require a detailed picture of the rest of the polymerase. This is what we are aiming for in our new FLUPOL project. In a joint effort with other European laboratories, and with financial support by the European Commission, we will explore both structure and function of this ke...

Ring-around-the-cell

...y, but the two together gave a much more extensive picture than either alone. The researchers found that the ring is composed of dot-like structures called podosomes, which are anchored to the cell membrane. When the osteoclast is on the move, these little dots amble randomly around the cell, but when t...

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers

...net, and the study as a whole gives a much clearer picture than ever before as to our place in nature." Dr Kate Jones from the Zoological Society of London adds: "Not only does this research show that the extinction of the dinosaurs did not cause the evolution of modern-day mammals, it also provides us wi...
