Beyond batteries: Storing power in a sheet of paper

...o power a small device such as a pacemaker without introducing any harsh chemicals such as the kind that are typically found in batteries into the body, Pushparaj said. The materials required to create the paper batteries are inexpensive, Murugesan said, but the team has not yet developed a way to inexpensi...

New, more direct pathways from outside the cell-to-cell nuclei discovered

...rry extracellular material into the cell nuceli by introducing fluorescent latex beads into the area outside of the cell. They then observed the cells phagocytose (eat) the beads, which gradually moved to the nucleus. The arrival of the phagosomes and their loads at the nucleus was marked by the illumination of ...

American Chemical Society's Weekly PressPac -- July 25, 2007

...search on potentially dangerous research projects; introducing ethical discussions into the classroom to sensitize undergraduate and graduate students to the possible misuse of scientific research, even their own; and the need for scientists to adapt a new, more vigilant and intentional way of thinking about the...

Species detectives track unseen evolution

...nary splinter group from their look-alike cousins, introducing uncertainty to biodiversity estimates globally. Markus Pfenninger and Klaus Schwenk searched the Zoological Record database (1978-2006) to pinpoint reports of hidden (cryptic) species both biogeographically and taxonomically, and found 2207 example...

Cells take risks with their identities

...adult skin cells to embryonic stem cells by simply introducing four key genes. Given the right signals, inactive developmental regulators primed for transcription could roar to life. This is a new model for regulation of the developmental regulators, Young maintains. It could bring us a step closer to reprogra...

Study provides new data about the laws governing embryo development in organisms

...ted around 45,000 different in silico experiments, introducing variations in twenty parameters. The results have enabled them to identify the most important system parameters and showed that the biological mechanism maintained its functionality in 91% of the cases analyzed. According to Miln and Buceta this stud...

Biocontrol of invasive water hyacinth contributes to socioeconomic and health improvements in Africa

...l programs can present some hazards. The risks of introducing non-native predatory species must be carefully evaluated before they are introduced. These risks include invasiveness by the control agents themselves and unintended effects on non-target species. Biocontrol agents must also be carefully monitored...

Penn researchers report that gene therapy awakens the brain despite blindness from birth

...ted for gene therapy. Gene therapy, performed by introducing a working copy of RPE65 into the retina, restored eye function in canines. Yet, it was previously unclear if the brain could receive the restored sight. The team found that gene therapy to the eye dramatically increased responses to light within t...

Among the reports other key points and conclusions: Renewable energy and efficiency markets are growing more global and enjoying easier access to capital markets; ...

NJIT professor says certain home shapes and roofs hold up best in hurricane

...eatures to alleviate these local pressures such as introducing a central shaft which would function by creating a connection between the internal space and the roof ridge considered to be the location of the largest depression. This connection helps balance pressures leading to a significant reduction in the roo...

Fat fish put obesity on the hook

... study, researchers caused obesity in zebrafish by introducing the same type of genetic mutation that causes severe obesity in humans. The genetic change blocks the activity of a receptor, the melanocortin-4 receptor, which is at the heart of a device in our brains called the adipostat. The adipostat regulates ...

Rutgers: GM/GMO/Biotech crop containment strategy

...b advocate an alternative and more secure means of introducing genetic material into a plant. In GM crops today, novel genes are inserted into a cell nucleus but can eventually wind up in pollen grains or seeds that make their way out into the environment. The two researchers at Rutgers Waksman Institute of M...

Oregon researchers involved in new Clovis-age impact theory

...nce Berkeley National Laboratory had been quietly introducing the theory to their professional colleagues. Douglas Kennett, with Erlandson watching, detailed the theory May 19 to a fully packed UO classroom, where students and faculty members from archaeology, art history, anthropology, biology, geology, geog...

Genome of yellow fever/dengue fever mosquito sequenced

..., the payoff is potentially great, Tu said. "By introducing TEs in a more or less random way to see what happens to the laboratory mosquitoes, the TEs become a tool to study the genetic mechanism of mosquito-virus interaction, to help us understand mosquito biology and reveal new ways to interfere with diseas...

First demonstration of new hair follicle generation in an animal model

...rather than just a scar, explains Cotsarelis. By introducing more wnt proteins to the wound, the researchers found that they could take advantage of the embryonic genes to promote hair-follicle growth, thus making skin regenerate instead of just repair. Conversely by blocking wnt proteins, they also found that...

Alien plants attack using 'resource conservation' as weapon, researchers say

...riety of removal methods, such as weed-whacking or introducing natural predators of the invasive plants, said study co-author Peter Vitousek, professor of biological sciences at Stanford. To determine which species warrant action, some government agencies in several countries, including the U.S. National Park ...

Middle- and high-school students from across Delaware also will be involved in hands-on research demonstrations in her lab through programs su...

Life-long learning -- nature provides natural inspiration for education

...e of knowledge transfer and life-long learning. By introducing modules which teach the use of Biomimetic product development, students are also exposed to the concept of incorporating scientific, social, economic and ecological aspects. In this way, scientists aim to expose students to a holistic approach to tea...
