The longest carbon nanotubes you've ever seen

...ov and Mark Schulz collaborated with post-doctoral researcher Yun Yeo Heung and students to develop the technique. The researchers partnered with First Nano, a division of CVD Equipment Corp. of Ronkonkoma, N.Y., to use their laboratory and a specialized furnace called the EasyTube 3000. With the equipment, ...

Study shows continued success for new HPV vaccine against virus responsible for cervical cancer

...r. Ault, one of the authors of the study and a key researcher in the development of the vaccine. "The two main things to emphasize are the vaccine efficacy and the safety. These clinical trials have consistent efficacy around 98 percent. And severe reactions to the vaccine appear to be rare. According to ...

DNA-damage test could aid drug development

...re generated. Shuga first worked with postdoctoral researcher Jing Zhang in the Lodish lab to adapt techniques from an established cell-culture system based on mouse fetal liver cells to create a new system based on adult red cell precursors from mouse bone marrow. Shuga patiently optimized the system, which al...

100 percent of pregnant women have at least one kind of pesticide in their placenta

...lacenta (156.73 ng/g lipid). Surprisingly, the UGR researcher discovered that some patients?placentas contained ...s (total fusion of the urethral folds). The UGR researcher underlines the fact that, in spite of "inadvertent exposure", "it is possible to control pesticide i...

Asexual worm quickly adapts to soil contamination

...an the worms from unpolluted soil. Dutch-sponsored researcher Agnieszka Doroszuk demonstrated this in her study into the long-term effects of environmental pollution on soil organisms. Environmental pollution is an important cause of stress in natural populations. This not only has consequences for the size, ...

New study examines 'brain's own marijuana'

A researcher at the University at Buffalo’s Research Institute on Addictions (RIA) is investigating the “brain’s own marijuana?-- called endocannabinoid -- in the regulation of stress, stress-related behavior and anxiety. A five-year, $1.7 million grant from the...

Implanting dopamine generators in brain cells obtains improvement in Parkinson's in monkeys

...first name amongst the contributors is that of the researcher Waldy San Sebastián. On this occasion the research was extended to a greater number of non- human primates and for a longer period of time. The procedure involved implanting cell fragments extracted from the carotid body in the striate area of the...

Genome of yellow fever/dengue fever mosquito sequenced

...of biochemistry at Virginia Tech, who was a senior researcher at the University of California, Riverside, is involved in this process that has so far validated about 80 percent of the 15,419 predicted protein coding genes in Ae. aegypti. He explains, "An important part of this project is gene annotation which p...

A new portable biosensor detects traces of contaminants in food more quickly and cheaply

...ts in the sample. According to Isabel Pividori, researcher at the UAB Sensors and Biosensors Group and co-director of the study, "due to their characteristics, such as their ability to carry out measurements in the field, the biosensors are analytical tools which have numerous applications in the agro food i...

Study of protein folds offers insight into metabolic evolution

...f crop sciences Gustavo Caetano-Anollés, principal researcher on the study, which was co-written by graduate student Hee Shin Kim and emeritus professor of cell and developmental biology Jay E. Mittenthal. "We are using the techniques of phylogenetic analysis that systematicists used to build the tree of life, ...

Fused nasal bones helped tyrannosaurids dismember prey

...of the tyrannosaurid, says a University of Alberta researcher whose finding demonstrates how a fused nasal bone helped turn the animal into a "zoological superweapon." "Fused, arch-like nasal bones are a unique feature of tyrannosaurids," said Dr. Eric Snively, a post doctoral research fellow at the Universit...

Executable biology -- Computer science sheds light on animal development

... variety of biological systems, explains lead EPFL researcher and biologist Dr. Jasmin Fisher. "Once a robust model has been built of a particular system, it can be used to get a global, dynamic picture of how the system responds to a variation ?such as a drug or a genetic mutation. Preliminary studies could be...

Bats get the munchies too!

...y be due to a matter of taste or flavour? explains researcher Francisco Sanchez, “The perception of sweetness versus bitterness may vary according the type of sugar and the amount of ethanol consumed. The combination of sucrose and ethanol may just have tasted better than either ethanol and fructose, or ethanol...

Switching genes to overdrive improves muscular dystrophy symptoms in mice

...sease,?said Bruce Spiegelman, PhD, the Dana-Farber researcher who led the team along with Christoph Handschin, PhD, formerly of Dana-Farber and now at the University of Zurich. Other authors are from the University of Iowa College of Medicine. Duchenne muscular dystrophy (DMD) is the most common type of musc...

Fast and slow -- How the spinal cord controls the speed of movement

...ease states." David McLean, Cornell postdoctoral researcher in Fetcho’s laboratory, was the first person to discover the pattern of neural activation and how it was associated with speed of movement. He is the lead author on the study. The researchers worked with 4 millimeter-long larval zebrafish (Danio ...

Biodegradable microspheres deliver time release vaccines, stimulate different immune response

...ren't effective," says Jenny Wilson-Welder, a lead researcher on the study. Wilson-Welder and her colleagues initially began their research looking for a way to eliminate the need for booster vaccinations, by developing a vaccine delivery system that released the vaccine into the system slowly over time. Th...

Brain maps online

...' of the brain," said Shawn Mikula, a postdoctoral researcher at UC Davis who is first author on a paper describing the work. The high-resolution maps will enable researchers to use "virtual microscopy" to compare healthy brains with others, looking at structure, gene expression and the distribution of diffe...

Fat overrides effects of vitamin C

...iochemistry? says Emilie Combet, the post-doctoral researcher working on the project, who will be presenting her results at the Society of Experimental Biology’s Annual Main Meeting on Monday 2nd of April. The incidence of cancer of the proximal stomach has been increasing over the last 20 years for which envi...

Deconstructing brain wiring, one neuron at a time

...d cells," says Ian Wickersham, Ph.D., postdoctoral researcher and lead author on the project. With the critical gene deleted from its genome, the virus is marooned inside a cell, unable to spread beyond it. However, supplying the missing gene in that same cell allows the virus to spread to cells that are di...

Fish extinctions alter critical nutrients in water, study shows
