DNA Molecules Used To Assemble Nanoparticles

...assembled dendrimer clusters were shown to be well formed and functional. "This is the proof-of-concept experiment," Choi said. But now that the assembly system has been worked out, other forms of dendrimer clusters are in the works. "If you wanted to make a therapeutic that targeted five drugs to five di...

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

...ich has been occurring ever since the oceans first formed four billion years ago. Conditions below the sea floor may most closely mimic the environment when life began. "There is a great deal of interest in the microbes of the Earth's crust because the strategies by which they survive may be similar to the...

Scientists Replicate Hepatitis C Virus in Laboratory

...haved like a true HCV infection by producing fully formed copies of the virus and releasing them from the host cell into the culture medium. Further testing is needed before the researchers can determine if the viral particles produced in this system are in fact infectious. Also, this system only represents...

Scientists decipher genome of fungus that can cause life-threatening infections

...ommunity already has designed a microarray and has formed aconsortium to further investigate the function of C. neoformans genes.The sequence data also provides the foundation for a broader genomeproject that aims to define the molecular basis for the C. neoformansspecies cluster, which includes three relat...

Scientists discover unique microbe in California's largest lake

...total volumeis about 7.5 million acre-feet. It was formed in the early 1900s, whenflow from the Colorado River was inadvertently directed to the SaltonBasin. Once the Army Corps of Engineers returned the river to itsnormal bed, the lake began to evaporate, gradually becoming one of thelargest hypersaline la...

MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks

...ich keeps trackof the thousands of complex species formed from pathway proteins as itsimulates reactions between them by a standard Monte Carlo method. Adistinguishing aspect of Moleculizer is its ability to generate proteincomplexes and reactions as they are needed, as opposed to generatingall potential co...

Scientists document complex genomic events leading to the birth of new genes

...some 2 has always intrigued primate biologists; it formed from the fusion of two mid-sized ape chromosomes and is the only cytogenetic distinction separating humans from apes. At the molecular level, however, the differences among the species are much more complex. Bork's team systematically searched the c...

New insight into people who 'see' colors in letters and numbers

...em distinguish shapes such as triangles or squares formed by the graphemes. In another experiment, the researchers found that synesthetic color helped the synesthetes pick out specific numbers or letters in a crowded display. The researchers found that the synesthetic colors really did help the synesthetes...

RNA project to create language for scientists worldwide

...known as the RNA Ontology Consortium, has now been formed to do just that. "The consortium will develop a common vocabulary and scientific concepts relating RNA structure and function to allow RNA scientists worldwide to communicate with one another as well as to integrate different kinds of information th...

UCSD team discovers specialized, rare heart stem cells in newborns

...le tissue. "Furthermore, the cardiac muscle cells formed were totally mature and had the complete array of function that one would expect in completely differentiated heart tissue," said the study's co-first author Jason Lam, Ph.D. candidate in the IMM. The cells exhibited contractility, pumping ability, t...

In addition to demonstrating that the genetic programming techniques work, this sensing system could be useful for the detection of chemicals or organisms in la...

Wisconsin researchers identify sleep gene

...he mutation, a functional ion channel could not be formed on the cell membrane and potassium therefore could not flow through it. When the researchers first tested flies with the Shaker gene, they found that some of them with other mutations were normal sleepers. But these flies became short sleepers when ...

Stem cells from brain transformed to produce insulin at Stanford

...sulin and had not changed into other cell types or formed tumors. Kim noted that the amount of insulin produced wasn't enough to effectively treat diabetes. Still, the work is a first step towards that eventual goal. It also hints that neuronal stem cells have many potential uses beyond treating brain dise...

Basis for DNA ejection from single phage particles

...most all phages (also known as bacteriophages) are formed of a capsid structure, or head, in which the viral genome is packaged during morphogenesis, and a tail structure that ensures the attachment of the phage to the host bacteria. A common feature of phages is that during infection, only their genome is ...
