One species, many genomes

...quence variation in the DNA of these plants). To track down the variation in the genome of the different Arabidopsis strains, the researchers compared the genetic material of 19 wild strains with that of the genome of the lab strain, which was sequenced in the year 2000. Using a very elaborate procedure,...

Math that powers spam filters used to understand how brain learns to move our muscles

...nts that tested the ability of monkeys to visually track rapid flashes of light. Experiments using such rapid eye movements, or saccades, are a staple in studying how the brain controls movement. Initially, the animal learner made large errors, but also stored the information about its mistakes in a mem...

Dual-imaging technique useful before -- and during -- brain surgery

...d then transfer that data to the operating room to track those areas during actual surgery. This approach, Leach says, has already been used in 20 cases at Cincinnati’s University Hospital. “Combining tractography and functional MRI intraoperatively has been in use clinically for only a few years,” ...

Stroke study sheds light on left-right brain divide

...ailed to spot their errors and had difficulty keep track of the changing task rules. The group with damage ...at the right-hand side of the brain has in keeping track of our own actions and helping us to notice when we have made mistakes,’ Dr Hodgson added. ‘This typ...

Definitive evidence found of a swimming dinosaur

...eter-long trackway, located in La Virgen del Campo track site in Spain's Cameros Basin, contains the first long and continuous record of swimming by a non-avian therapod dinosaur. A team led by Rubén Ezquerra, Fundación Patrimonio Paleontológico de La Rioja, La Rioja, Spain, discovered the prints in an a...

Students invent protective pouch to enhance cell therapy

...ve developed ways, covered by a pending patent, to track the microcapsules with various imaging technologies. They and researchers elsewhere have struggled, however, to keep these encapsulated cells alive within the body, mainly because the cells often situate themselves where they do not have access to...

DNA repair proteins monitored at double-strand break

...utations, cell death or cancer, and the ability to track the process so closely will give researchers critical insights into what can go wrong with DNA repair. This could lead to novel ways to make cancer cells more sensitive to therapy by blocking their ability to repair double-stranded breaks caused by c...

Bones in motion: Brown scientists to create new 3-D X-ray system

... precision and detail. Researchers will be able to track 3-D skeletal movements with 0.1 millimeter accuracy and see the equivalent of 1,000 CT images per second. The result will be a powerful tool with applications for basic and applied research: testing new theories of biomechanics, such as muscl...

Sandia researchers take new approach to studying how cells respond to pathogens

...een to red and give researchers the opportunity to track proteins and see, for example, the dynamic cellular production of proteins or protein-binding processes inside or on the surface of the cells. The team is developing one platform with two complementary microfluidic modules -- one for trapping and ...

UCI scientists reconstruct migration of avian flu virus

...n, the UCI analysis is the first to systematically track the migration of H5N1 through its evolutionary history, adding new details that identify the relative importance of the geographic and evolutionary advances the virus makes. From 192 samples obtained across Eurasia, the UCI team reconstructed the ...

Imaging techniques permit scientists to follow a day -- or four -- in the life of a cell

...in can be fluorescently labeled, so scientists can track the glowing protein with a microscope and observe what it's doing and where it's going inside the cell. This microinjection technique is similar to those that are used to create cloned and transgenic organisms, and it can also be applied to more comp...

Soft-cell approach cuts animal tests

...rganism failure many months or even years down the track from initial exposure. The application of in vitro methods could open new possibilities for toxicity testing of industrial chemicals, occupational and environmental contaminants, combustion products and respiratory therapeutics and lead to a bett...

Robotic exoskeleton replaces muscle work

...nated. In addition, patients are less able to keep track of exactly where and how their muscles move, which makes re-learning movement difficult. Typically, robotic rehabilitative devices are worn by patients so that the limb is moved by the brace, which receives its instructions from a computer. Such ...

Research finds music training 'tunes' human auditory system
