Swiss researchers develop all-in-one remote control gene expression tool

...esearchers have combined several gene manipulation techniques and incorporated them into a single lentiviral vec...n all-in-one tool like this ?efficiently combining techniques that each previously required separate delivery ?will likely see wide use in genetic research and in...

'Virus chip' detects new virus in prostate tumors

...archers say. While most other virus identification techniques require researchers to look for only a small number of candidates, the virus chip represents an unbiased search, since all known viruses are tested simultaneously. The study is part of an on-going effort launched two years ago by DeRisi and Ganem ...

Patterns in genome organization may partially explain how microbial cells work

...regated in any particular way inside the cell. New techniques that attach fluorescent "reporter" markers to predetermined spots on chromosomes have indicated that many bacterial genes tend to be found at specific cellular locations. Patterns are not obvious in the sequences of prokaryotic genomes, which led the...

Sequencing our seas

...l ecologists have had fairly rudimentary tools and techniques to bring to bear on their research to date, DeLong said. But now with the ability to sequence vast amounts of DNA in shorter time periods, the science is pressing forward. DeLong and his colleagues saw a unique opportunity for a "proof-of-principle"...

UC Berkeley researchers create a biologically-inspired artificial compound eye

...to the eyes." While conventional microfabrication techniques are expensive and use high temperatures, Lee and his team borrowed from nature, using a low temperature system, photopolymerization, and self-aligning, self-writing technology. To create the artificial eye, the team first needed to construct a hemis...

Enzyme inhibitors block replication of SARS virus

...e findings were made by using rapid drug discovery techniques developed in the Wong lab to screen large numbers of weak enzyme inhibitors, and then attaching additional compounds to look for stronger reactions. Research Associate Chung-Yi Wu, a member of the Wong lab, is the paper's lead author. He said the f...

Rice bioengineers pioneer techniques for knee repair

...icular knee cartilage. His lab is also working on techniques to grow replacement knee menisci, the kidney shaped wedges of cartilage that sit between the femur and tibia and absorb the compressive shock that the bones undergo during walking and running. Over the past 18 months, he and his students Adam Aufderh...

Researchers get neurons and silicon talking

...rding which ones fired using standard neuroscience techniques while tracking the signals coming from the chip. The development of the interface and chip are crucial for this new technology, but problems remain. "Right now, we need to refine the way we stimulate the neurons, to avoid damaging them," says Vassan...

Evolutionary biology research techniques predict cancer

...rent cells within the tumors. Using computational techniques to analyze the data, the researchers calculated measures of diversity inside the tumors. Essentially, they counted cell varieties and measured the genetic difference, or divergence, between those varieties. "Simply put, we took ecology measures of sp...

Great (taste) expectations: Study shows brain anticipates taste, shifts gears

...aisman Center using state-of-the-art brain imaging techniques and distasteful concoctions of quinine on a cohort of college students, reveals in detail how the brain responds to a manipulation intended to mitigate an unpleasant experience. "There is a potent impact to expectancy," says Nitschke, who, with his ...

Flesh-eating bacteria escape body's safety net

...e infection model. Special fluorescent microscopy techniques were used to observe how the Strep enzyme dissolved the DNA nets and allowed bacteria to float away from the neutrophils. "The experiments explain how this DNA-degrading enzyme contributes to the severe infections produced by certain strains of Stre...

New RNAi tools enable systematic studies of gene function

...cess. Therefore, TRC developed the high-throughput techniques and quality-control measures required for such genome-scale studies. "It is a distinct challenge to achieve consistent and cost-effective RNAi methods and we placed a strong emphasis on this part of the process," said David Sabatini, member of Whiteh...

"Furthermore, studying enzymes that inactivate antibiotics can serve as a foundation for the development of new combination therapies for resistant bacterial strains. Studying antibiotic resistance from an evolutionary ...

Study suggests that publicly available genome data may contain small but significant errors

...ing humans has also been elucidated. However, the techniques used to derive these genetic sequences are imperfect, and many researchers may be unaware of potential errors lurking within the publicly available published, or "canonical" sequence. If an organism's genome is unstable, variable, and contains rearr...
