Scientists characterize proteome of human cornea

...ion people in the United States wear eyeglasses or contact lenses to correct nearsightedness, farsightedness, or astigmatism. These vision disorders are often the result of incorrect curvature or irregular shape of the cornea and are the most common vision disorders in this country. Other diseases that affec...

Getting close to nature is good for you

...y is known as ecotherapy: restoring health through contact with nature. Use of wildlife in some therapies is reported to improve quality of life, write the authors. Smaller animals (for example, squirrels, owls, and raccoons) have been used successfully in therapies for children with emotional and behaviour...

Retinal scans eyed for New Mexico show cattle

...nd identify all animals and premises that have had contact with an animal disease of concern within 48 hours of an initial diagnosis. In a first-of-its kind project for New Mexico, scientists tested 35 market steers from 18 Quay County farm families, using a combination of eye-scanning and radio frequency i...

Life in deadly conditions

...cells. The cellular components that are in direct contact with the brine around them need their own adaptation strategies. These components are the cell membrane and the proteins that have to function outside the cell. Michaela Falb discovered, using theoretical analysis as part of her doctoral thesis, that...

'Nanospheres' that block pain of sensitive teeth

...e of the tooth. Heat, some chemicals, and physical contact can cause the fluid in these channels to move ?in or out ?triggering the nerve endings and causing sharp pain. If these channels (or 'tubules') are fully or partially blocked, the flow can be reduced and the pain stopped or significantly reduced. C...

MIT researcher finds neuron growth in adult brain

...entative tendrils that grow around or retract from contact with neighboring cells. Dendrite tips that look like the thinnest twigs grow longer. Of several dozen branch tips, sometimes only a handful changed; in all, 14 percent showed structural modifications. Sometimes no change for weeks was followed by a g...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...killing peptide worked best when it came in direct contact with the cell membrane. "It is possible that if the lytic peptide has no interaction with the membrane it is targeting, it cannot kill," Leuschner says. The research group next looked at nude mice ?mice lacking immune systems ?that carried xenograf...

Katrina floodwaters not as toxic to humans as previously thought, study says

...ity known as the "East Bank," where the main human contact with the floodwaters occurred. The samples, which included both surface waters and bottom samples, were taken within five to nine days after flooding occurred. Additional samples were also obtained from the 17th Street drainage canal, after pumping o...

The dangerous legacy of lead

...ly occurs in older housing, where children come in contact with lead paint and dust and, as a result, may experience intellectual impairment, behavioral problems and lifelong health issues. The effects of lead in children are irreversible, so public health officials are primarily focused on preventing these ...

How Fruitflies Know It's Time for Lunch

... metabolism and growth organ in flies. Other axons contact the protocerebrum, a structure close to brain centers for learning and remembering odors. A third set of these axons extend to throat muscles—which is surprising because most subesophageal ganglion neurons have no connection to motor function. All to...

How does Mycobacterium tuberculosis infect the lung?

...se this is the part directly involved in the first contact with the Mycobacterium. As they report now in the international open-access medical journal PLoS Medicine, they studied 74 individuals, 40 of whom had TB, 25 had other inflammatory lung diseases, and 9 had neither active TB nor lung inflammation and ...

Leading lampreys to slaughter: Pheromone for scourge of Great Lakes identified

The lampricide is tanker-trucked to streams, some of them in populated areas, in an expensive, labor-intensive and unpopular undertaking. The GLFC is eager to use a synthetic form of the newly found pheromone to replace the ...

Lateral thinking produces first map of gene transmission

...rough methods such as bacterial viruses and direct contact between cells. "The idea of lateral genetic transfer has been around for a few years, but what was missing was a good, hard, rigorous look at it," Professor Ragan said. "Previous studies have either been small scale, or used statistical shortcut ...

Langerhans cells regulate immune reactions in the skin

"Langerhans cells are thus not required to generate immune responses in th...

Wild birds help to create human flu vaccine
