New battery technology helps stimulate nerves

...onductivity and stability," says West. A critical advantage of the new battery technology is lifespan: "If you're going to implant these things, you want a (battery) lifetime of at least 10 years," says West, whose organosilicon batteries are projected to power the tiny implantable devices for more than 12 ye...

PET imaging reveals the immune system at work

...how poorly the body is faring against disease. The advantage of using the new PET technique, said Witte, is that surgical procedures are avoided and a PET scan can give clinicians a picture not only of an afflicted part of the anatomy, but of the whole body over time and in a way that portrays the body's respo...

Jefferson biologist coaxing human embryonic stem cells to make dopamine with simpler, faster method

Limiting the damage in stroke

...tion of IKK2 at any time in neurons. "The unique advantage of this system is that we can specifically induce or block this signaling pathway at virtually any time and selectively in neurons," Wirth emphasizes. Putting all of this expertise together permitted the researchers to get a clear picture of IKK2's r...

Changes to embryos can elicit change in adult fish

...ever is long, this gives the jaw a high mechanical advantage and the jaw can produce more force for biting. Whe...-lever is long, that results in a lower mechanical advantage and a better design for suction-feeding. This negative correlation is produced by genetic integratio...

Algal protein in worm neurons allows remote control of behavior by light

...atory. In their experiments, the researchers took advantage of the light sensitivity of the algal channel protein by introducing expression of a modified form of ChR2 in specific C. elegans neurons and muscle cells. The researchers found that when this form of ChR2 was expressed in muscle cells, blue-light ac...

USC researchers track down the stem cells that create feathers

...ed into organs in nature. In this way, we can take advantage of the distinct patterns of the feather as a model to understand the fundamental principles of organ formation and regeneration," Chuong notes. "Nature is the best teacher for tissue engineering. What we decipher from our animal models can then be ap...

Plants, too, have ways to manage freeloaders

...so vulnerable to exploitation - one species taking advantage of another. What mechanisms could prevent this?" She and colleagues proposed several years ago that in cooperative relationships, one member must have the upper hand in enforcing good behavior. This could involve shutting down resources to nodules i...

Mouse study: New muscle-building agent beats all previous ones

... although the new agent seems quite promising, its advantage in potency also requires extra caution. "We don't know what else the new agent is affecting or whether those effects will turn out to be entirely beneficial," says Lee. Lee says they also are conducting experiments with the mice now to see whether ...

T-rays: New imaging technology spotlighted by American Chemical Society

...n be used to sense and image objects. A particular advantage of T-ray systems is that they can also give spectroscopic information about the composition of chemical and biological material, and are safer for biological applications than X-ray photons, that emit a million times more energy. Advances presented ...

Preclinical study of a new brain tumor therapy

... and Ludwig-Maximilians-University in Munich) took advantage of previous research that showed how to distinguish between cancerous and healthy cells through the detection of molecules known as epidermal growth factor receptors (EGFR). The glioblastoma cells overexpress EGFR (that is, in comparison with normal ...

Scientists develop protein-sequence analysis tool

... has become impractical for those who wish to take advantage of the increasing number of sequences in protein databases, Shanklin said. "Yet this growing data resource contains a wealth of information for structure-function studies and for protein engineering," Shanklin said. "We developed CPDL as a general t...

Antibacterial coatings cut infection rates

...Professor Griesser said. Furanones have a unique advantage in that they act differently to other antibiotics. Unlike antibiotics, they don't kill bacteria. This means that the furanone compounds should not cause bacterial resistance, according to microbiologists. "When bacteria sit on the surface, they firs...

3D ultrasound device poised to advance minimally invasive surgery

...esearchers. Endoscopic surgical methods have the advantage of reduced postoperative pain and a faster recovery. However, the two-dimensional ultrasound imaging now available offers surgeons only a limited view, which can impede their depth perception and make such procedures difficult to master. "Our ultras...

Diabetes researchers pioneer islet cell xenotransplantation in primate studies

...owth potential post-transplant, considered a major advantage over adult pig islets. The diabetic animals were treated with a CD28/CD154 co-stimulation blockade-based immunosuppressive regimen, and achieved sustained insulin independence (median survival >140 days with one animal now at 300 days) without e...

Cellular scale drug delivery from the inside out

...ove the caps and release the drug," Lin said. "The advantage of using a magnetic trigger as opposed to a ultraviolet light trigger is that there's no limit to the depth of tissue we are able to probe ?think of an MRI." Beyond the possibilities for intercellular drug delivery, the nanospheres may provide the k...

Simple idea to dramatically improve dengue vaccinations

...ody ?could help overcome immunodominance by taking advantage of the relative isolation of lymph nodes throughout the body. Each person has hundreds of lymph nodes. Deem believes vaccinations at four different sites, served by four different lymph nodes, could allow the body to simultaneously develop immune res...

Researchers map of genetic variations implicated in disease

...ions, which presumably have favoured immunological advantage (e.g. resistance to infectious disease), can spread across haplotypes and populations. Professor John Trowsdale, at the Department of Pathology, University of Cambridge, said, "The region, called DR-DQ, where we find this island of stability is one ...

Underdogs in the understory: Study suggests nature favors rarer trees

...trees age. The authors say rare trees may have an advantage because they are less vulnerable to animals, fungi, and microorganisms that prey on common trees and because they don't have the same resource needs as common trees. Trees in "monoculture" forests, where all individuals are the same species, are ve...
