Deep in the ocean, a clam that acts like a plant

...lack depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies. Around hydrothermal vents deep in the ocean live communities of giant clams with no gut and no functional digestive system, depending on symbiotic bacteria to use energy locked up in hy...

Tears reveal some of their deepest secrets to researchers

... microscopic droplets of the oily substance, which allows the instrument to detect different components based on electrical charges and mass. Nichols points out that researchers have used other techniques, such as chromatography, to characterize types of lipids in the tear film, but advances in mass spec...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

... distributed information and data storage not only allows one to collect information more effectively, but also makes the data immediately available to researchers worldwide," said Kai Nan, director of CNIC’s Network Technology and Applications Research Laboratory. "The end result is a dynamic research comm...

Biologically inspired sensors can augment sonar, vision system in submarines

...aving a man-made parallel of the biological system allows us to learn much about both basic science and engineering," Liu said. "To actively learn from biology at the molecular, cellular, tissue and organism level is still the bigger picture."...

Targeting tumors the natural way

...n their surfaces than do normal cells, a fact that allows scientists to pinpoint tumor cells lurking among the body's scores of cell types. A popular approach employs a cell-binding agent, such as a monoclonal antibody, that is powerfully attracted to the target receptor and holds fast to any cell displayin...

Magnetic system could be key to surgery without scars

...hnique, which is still in the developmental stage, allows for magnetically maneuvering laparoscopic surgical...oned, the instruments can be locked in place. That allows a much greater range of maneuverability and the surgical team can more easily reposition the camera ...

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

...irus by devising a novel virus culture system that allows replication of patient-isolated virus in nontransformed hepatocytes, instead of culture-adapted virus strains in transformed cell lines. The related report by Lázaro et al, "Hepatitis C virus replication in transfected and serum-infected cultured hu...

A revolution in the monitoring of unborn babies

... and be attached to a machine. No other technology allows them to do this. It took 15 years of pioneering work and enterprise, with funding from Action Medical Research and Venture Capital, to develop the fetal heart monitor. Researchers believe the device has the potential to benefit 70,000 at risk babies...

Ocean's 'twilight zone' may be a key to understanding climate change

...l Ocean). The twilight zone acts as a gate that allows more sinking particles through in some regions and fewer in others, complicating scientists' ability to predict the ocean's role in offsetting the impacts of greenhouse gases. Using new technology, the researchers found that only 20 percent of the...

Engineering the heart piece by piece

...ng and now at the University of North Carolina. It allows up to 11 specimens of tissue to be grown in the same conditions at the same time, while allowing each specimen to be “stretched?using a specially made device that can both apply forces and measure the forces generated when the tissue begins contracti...

New nanotechnology able to examine single molecules, aiding in determining gene expression

...of material that must be analyzed. Nanotechnology allows us to push down to the level of individual transcript molecules." "We are likely to see more of these kinds of highly multi-disciplinary research aimed at single molecule sequencing, genomics, epigenomic, and proteomic analysis in the future," add...

Satellites shed light on global warming

...wn as the Advanced Synthetic Aperture Radar (ASAR) allows Envisat to produce high-quality images of ice sheets because it is able to pierce through clouds and darkness. In addition to mapping ice boundaries, Rott used repeat-pass ASAR image data to map the flow velocities of glaciers. All the glaciers, ...

Anti-dandruff compound may help fight epilepsy

...f shampoos. Li explains that ZnPy has a shape that allows it to fit into the gate region of the channel protein and allow more potassium flow. “If you think of these channels as doors on the cell’s surface,?Li says, “then ZnPy made this door both easier to open and stay open longer. It’s like a tunable hing...

New test helps identify hepatitis C patients at high risk of developing cirrhosis

...developing cirrhosis," said Cheung. "This test allows both physicians and patients to make an intelligent decision about the urgency of beginning antiviral therapy," he said. "If a patient turns out to be low-risk, we might advise the patient to consider deferring treatment, avoiding unnecessary side...

Scientists reveal structure of gateways to gene control

... the exact DNA sequences for all these nucleosomes allows us to precisely map their positions across the entire genome," explains Schuster. The map reveals, for the first time, precisely which DNA sequences are part of the control-center's H2A.Z nucleosome for each gene in the yeast genome. Also for the f...

MIT's ocean model precisely mimics microbes' life cycles

...light, temperature and nutrient availability, then allows the ocean to self-select those most fit for survival in any particular area. What emerged after the model completed its 10-year virtual evolution -which took four to five days on a cluster of parallel computers-is a phytoplankton community with me...
