Nanoparticles offer new hope for detection and treatment

...ewly forming blood vessels. When the nanoparticles hooked the "loops" on the new vessels' cells, they revealed the location of the tumors. Nanoparticles are particularly useful because of their adaptability, according to Lanza, who sees patients at Barnes Jewish Hospital. "We can also make these particles ...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...tle behavior indicated sea turtles swim and become hooked in shallower waters than tuna, the target species of most longline commercial fishing. According to Duke University researchers, more than 200,000 loggerheads and 50,000 leatherbacks are accidentally caught annually by commercial longline fisheries. ...

Innovative collaboration brings Arctic science into the classroom

...h students and the public, using a satellite phone hooked to a laptop computer for internet communications. According to Holmes, "Getting kids excited about science is the most important thing. If they realize that science is an exciting process as opposed to a bunch of boring facts to memorize from textboo...

Six previously blind patients detect light, motion, identify objects with retinal prostheses

...relessly stimulated through an external controller hooked up to a head-mounted video camera. This study is being conducted under a Food and Drug Administration Investigational Device Exemption (IDE), and is funded by Second Sight Medical Products, Inc., Research to Prevent Blindness, and the Fletcher Jones...

Student scientists create living bacterial photographs

...blue-green algae to the E. coli cell surface. They hooked the light receptor up to a sensor in E. coli that normally senses salt concentration. Instead of sensing salt, the bacteria could sense light. The light receptor was then connected to a system in the bacteria that makes pigments. When light strikes ...

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

... In the study that Lowery reports, the researchers hooked "Y"-shaped anti-HER2 antibodies to nanoshells, and the antibody bound to HER2 over-expressing breast cancers. They then applied these immunonanoshells to the top of laboratory breast cancer cells, and used laser light to heat the agent. Researchers t...

Gene chip technology shows potential for identifying life-threatening blood infection

... accident or fall. Because these patients are also hooked up to IV fluids, catheters or ventilators, they are also prone to bacterial infections, including pneumonia, that can quickly spiral out of control and lead to sepsis. Although both conditions are life-threatening because of their threat to major ...

Hopkins researchers discover how brain protein might control memory

...ith other proteins normally found in the brain and hooked two known to be involved in transporting materials into and out of cells. "Moving things in and out of cells is critical for normal brain cell function. We were extremely excited that Arc might somehow be involved in this transport because it link...

Wheat can fatally starve insect predators

...nts for the insect. Instead, the promoter would be hooked up to a lectin or toxin gene and inserted into the cells. When larvae manipulate the promoter, they would receive gut-altering lectin instead of nutrients. To advance their investigation into developing more resistant plants, the researchers are b...

When your brain talks, your muscles don't always listen

...an index finger of each subject. The electrode was hooked up to a computer to record the electrical impulses as they travel from neurons to the muscle fibers. As the index finger was held steady in a small harness, each subject was asked to use the finger to follow the outline of a sinusoidal curve, with...
