A new look at the state of the oceans

...led recently and, at present, holds more than 3000 images and over 500 species descriptions. Free access to ...base enables all registered users to add their own images and data, and to supplement existing data records. All newly entered data are reviewed, and, if nece...

New light microscope sharpens scientists' focus

...06, the collaborators were taking strikingly clear images of a number of cellular structures, including acti...now, Hess and Betzig have focused on creating PALM images with a single fluorescent protein, which limits them to mapping a single target protein per sample. ...

Molecular DNA switch found to be the same for all life

... using single-particle electron microscopy. Their images revealed for the first time how the ORC when bound to ATP forms a AAA+ helical structure much like the DnaA superhelix found by Berger and his team in their E.coli study. "This work provides the first view of the mechanical transitions in ORC driv...

Even a little cooling helps after cardiac arrest

... at the study site, using video cameras to capture images of as many birds as possible. The results proved encouraging as the video-based estimates of the bird community were in close agreement with those from the snail-trematode analysis. "The more birds there were at a site, the more parasites," Hechinger...

New GI technologies improve internal organ visualization

..., the patient swallows a small camera that records images of the intestinal tract. To complete a double balloon enteroscopy, doctors use a scope fitted with two balloons to navigate the entire small bowel. When inflated with air, the balloons can expand sections of the small intestine to allow the camera ...

Virtual realities against pain

...action techniques (ADTs) recently developed use 3D images combined with dynamic audio stimuli, making the techniques more likely to meet the requirements of an ideal distractor than the traditional distraction methods such as watching a film or playing a simple computer game. The ADTs simulate real-life s...

Everything in its place: Researchers identify brain cells used to categorize images

Radioactive scorpion venom for fighting cancer

...nd in scorpion venom. For many, this will conjure images of Spiderman's nemesis, the Scorpion. The purpose of this work is not science fiction, but rather to help to develop a promising new therapy for brain cancer. The venom of the yellow Israeli scorpion preferentially attaches to the cells of a type ...

New MRI technique quickly builds 3-D images of knees

Purdue creates new low-cost system to detect bacteria

...st important developments is being able to convert images to numbers, which makes it possible to classify the patterns," Rajwa said. "We are able to take images and convert them to numbers that uniquely describe every picture." The researchers used the new sy...

New tool tracks brain development in babies

... of the 10 neonates with ischemia, compared to the images obtained from the normal infants. The fiber pattern of the brain's white matter was disturbed in several areas of the brain, including the corpus callosum, which allows communication between the two hemispheres of the brain, and, most significantly, ...

Inside rocks, implications for finding life on Mars

...J. William Schopf and colleagues have produced 3-D images of ancient fossils -- 650 million to 850 million y... even though the fossils are exceedingly tiny, the images are sharp and crisp. So, we can see how the fossils have degraded over millions of years, and learn ...

Plants used to detect gas leaks, from outer space!

...al parts of the plant appear stressed in satellite images detecting reflected light. This remote-sensing technology can be used to detect any type of stress that causes asphyxiation of the plant roots. Steven and his colleagues are already considering other uses for the detection system. One such applic...

Is the brain wired for faces?

...ehavioral techniques. Subjects were shown pairs of images of similar human faces that had been morphed using computer graphics software, while the researchers observed how brain activation changed for more or less similar pairs of faces. They found that a small group of neurons in the "fusiform face area,"...

One fish, two fish: New MIT sensor improves fish counts

... larger than what could previously be studied. The images can be updated every minute, offering a chance to ...der the ocean floor. But when their reconnaissance images did not match the riverbeds, the researchers went back with a new approach, and determined that they...

Relationship of brain and skull more than just packaging

Major WHO study concludes calcium supplements can reduce complications during pregnancy

...fections." In contrast to the colorful but static images on the covers of scientific journals, actual proteins are constantly quivering from the thermal motion of their atoms. Drug-binding sites that may be closed most of the time can be transiently exposed by an imperceptible atomic shudder. "This 'foot i...

Report shows deforestation threatens Brazil's Pantanal

...ere Reserve. The CI scientists analyzed satellite images to compare the proportion of deforested areas with those that still have native vegetation. They concluded that agriculture, cattle grazing and coal mining are the major threats to the Paraguay River Basin, a significant hydrographical drainage of th...
