Sea coral's trick helps scientists tag proteins

...ight. "It was very surprising for us to observe an efficient Dendra photoconversion upon illumination with intense blue light," Konstantin Lukyanov said. "We still have no clear explanation for why Dendra differs from other Kaede-like fluorescent proteins." Sergey Lukyanov pointed out that the ultraviolet lig...

USC, Rice to develop bacteria-powered fuel cells

...ividually and in colonies ?but they are incredibly efficient at converting organic inputs to electricity, so we are confident that they'll be a great candidate for our fuel cells," Lüttge said. ...

When good DNA goes bad

... to forming Z-DNA, while the sequence AT is not as efficient at forming this structure. Analysis of the genome reveals that DNA sequences prone to forming the Z-DNA structure occur in 0.25 percent of the genome, according to Vasquez. She and her colleagues decided to find out whether Z-DNA itself had any eff...

Two NIH initiatives launch intensive efforts to find roots of common diseases

...d that this initiative will get off to a quick and efficient start that will genuinely produce important advances for all patients." Genetic Factors The genetic analysis of both GAIN and GEI will focus on the alternative spellings ?called single nucleotide polymorphisms or SNPs ?that normally occur in the ...

High-resolution light microscope reveals the fundamental mechanisms of nerve communication

...the calcium channels and the vesicles enabling the efficient release of neurotransmitters. These studies demonstrate for the first time that resolution below a half-wavelength of visible light is no longer reserved for the electron microscope when observing cells. As demonstrated by recently completed researc...

Strawberries by design

...rginia Tech have developed a new procedure for the efficient transfer of specific DNA sequences into the genome...worked hard to find a system that would enable the efficient transformation of strawberry. However, these efforts have fallen short of the requirements to suppor...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

...rus is kind of a gift from nature, a very safe and efficient virus, but nature never evolved it to be a human therapeutic. So, in a sense, we have to re-evolve it for that purpose," he said. ...

The diversity of marine life in the Gulf of Maine region is much greater than previously thought

Most human-chimp differences due to gene regulation ?not genes

...ly modified in the human lineage." This is a very efficient way to make big changes with very little effort, according to Gilad. By altering transcription factors, the entire regulatory network can change with very few mutations, increasing the impact and minimizing the risk. "The big question," he said, "is...

Tandem transcripts team together

...nse and therefore, are toxic and cannot be used as efficient drugs. The understanding that some gene pairs are naturally produced as fused proteins might lead, in the future, to the development of non-toxic engineered fused proteins that could be used as drugs." ...

FDA approves first medical device using rutgers biomaterial

...vented in 1997 and has progressed along a fast and efficient track to FDA approval ?a process that usually takes 10 years or more. The invention was made with initial research support from the National Institutes of Health and demonstrates how a federal agency's funding can reap benefits for the American publ...

HIV vaccine takes different tack to boosting immune response

... cells in which the SOCS1 was turned off were more efficient at stimulating the body's immune cells. Most immunization attempts to stimulate an immune response to HIV in the past have been disappointing, but Chen says his laboratory results hold promise to make current HIV vaccines work better. SOCS1 was foun...

Biofuels can replace about 30 percent of fuel needs with significant research and policy effort

...uch as accelerated domestication to make them more efficient energy crops. But doubling the productivity of energy crops will mean identifying constraints and correcting them with genomic tools. To make biofuels a truly practical alternative to petroleum, the group says there will need to be significant impr...

New crop of technology reveals plant health

...e modules, tools and methodologies that enable the efficient and flexible integration of 'augmented' plants and artefacts into ubiquitous computing applications which may range from domestic plant care to precision agriculture. "The main idea behind PLANTS is to develop a system that produces the optimal grow...

Oxidation defense in mosquitoes benefits malaria parasite

...toes determined that "mosquitoes have developed an efficient strategy to prevent the accumulation of 3-HK by converting the chemically reactive 3-HK to the chemically stable XA via transaminase-mediated reactions," said Li. The protein described in the PNAS article is responsible for this transforming of 3-H...

Even fish don't swim well when they're young!

... fish larvae are pretty feeble when it comes to an efficient mode of swimming called 'burst-and-coast'. Dr Ulrike Müller from Wageningen University studies how fish swim: "Fish larvae are the most critical life history stage. In marine fish more than 99% of the mortality occurs in the larval stage so anything ...

Scientists elucidate the kinome of key model organism

...compile data about genes and kinases in a fast and efficient way, which can be very useful for drug discovery and development. According to Dr. Smith, Dictyostelium provides a simple model in which to study conserved cellular processes, and illuminates a period in the evolutionary history of the metazoa aft...
