Priming embryonic stem cells to fulfill their promise

...ll.In their experiments, the UCSD researchers took advantage of theknowledge that the extracellular matrix in liver is comprised primarilyof just five proteins. They applied spots of all 32 possiblecombinations of the five proteins as engineered niches onto the surfaceof gel-coated slides, and then added mouse...

Whole genome fine map of rice completed

...ts, thus revealing the source of the hybridization advantage in hybrid rice. ...

The transparent organism: EMBLEM and Carl Zeiss give labs a unique look at life

...re assembled into a high-resolution film. Another advantage of SPIM is that the specimen is kept alive in a liquid-filled chamber, allowing scientists to track developmental processes like the formation of eyes and the brain in embryonic fish or other model organisms. The presentation of SPIM at scientific c...

Study finds more than one-third of human genome regulated by RNA

...ts in anyvertebrate.)In their latest paper, taking advantage of the most recentgenome-sequencing data, the team has compared human genome data withthat of the dog, chicken, mouse, and rat. For each of the microRNAs andprotein-coding genes that are common to these five species, the teamlooked for correspondence...

Color-blind method opens new doors in DNA sequencing

...articular dye. PME enables the researchers to take advantage of the entire visible spectrum, eliminating the problem of cross-talk between dyes, said Metzker. Because there are four lasers, scientists can manipulate the system so that each dye gives the same intensity of fluorescent signal, eliminating the ne...

UCSD researchers maintain stem cells without contaminated animal feeder layers

... proposed animal-free medium, the UCSD study takes advantage of a previously unidentified soluble factor this is secreted from mouse feeder layers to maintain stem cells' undifferentiated state and pluripotency, the ability to become all tissue types in the body. The scientists knew that a cocktail of various ...

Same mutation aided evolution in many fish species, Stanford study finds

... group of fish called the stickleback, nature took advantage of the same genetic trick time and again to allow freshwater species to shed their burdensome body armor and transform into a lighter, spryer fish. This is among the first times scientists have shown that the same genetic change is responsible for an...

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

... cellular activity over a period of time, bytaking advantage of the power of computers to generate the thousands ofpotential protein complexes and reactions that cells are able togenerate.The Molecular Sciences Institute is an independent nonprofit researchlaboratory that combines genomic experimentation with ...

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

...ew functions, however, they may confer a selective advantage to an organism, leading to the rise of lineage-specific genes over evolutionary time. Bork's team identified a total of 22 genes with more than one copy in humans but only a single copy in all other species tested. They then turned their attention t...

Falling ants glide back to trunk to avoid dangers of forest floor

...ak said. The gliding behavior would be a definite advantage for ants, like Cephalotes, that forage at the outer reaches of branches and are in greatest danger of being knocked off by wind gusts or passing monkeys. There is some evidence, Dudley said, that these ants sometimes purposely drop off the tree to av...

X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

... by how hard these muscles work. Now we have taken advantage of the fruit fly’s small size and shone light right through the whole animal, illuminating the working muscles during flight and probing the molecular motions deep within the muscle cells.?/p> These experiments uncovered previously unsuspected in...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

...ly going to its intended target." This work takes advantage of years of effort in the Therien laboratory focused on the design of highly fluorescent compounds. Polymersomes, which were developed by Penn professors Daniel A. Hammer and Dennis Discher in the mid-1990s, function much like the bilayered membranes...

International HapMap consortium expands mapping effort

...he original plan. This "Phase II" HapMap will take advantage of the rapid, high-throughput genotyping capacity of Perlegen Sciences, Inc., of Mountain View, Calif., to test another 4.6 million SNPs from publicly available databases, and add that information to the map. As a result of a grant competition last s...

Children's taste sensitivity and food choices influenced by taste gene

... coding for taste and olfactory receptors. We took advantage of this new knowledge to look at how variation in taste genes might relate to the taste likes and dislikes of children and parents." In the study, to be published in the February 2005 issue of Pediatrics, researchers compared taste sensitivity and f...

Computational Method Speeds Mapping of Cell Signaling Networks

...ncover molecular relationships. This is a distinct advantage according to Pe'er, who notes, "Unlike classical biochemical approaches where you need to know all of the intermediate players in a network, this system can detect indirect influences" between molecules. Pe'er suggests a similar technique could be u...

Turning viruses into allies against cancer

...gineering, viruses are being re-programmed to take advantage of their natural abilities to infiltrate, commandeer, replicate and destroy, but only in tumor cells and not surrounding healthy tissue. Several of these "oncolytic" (cancer-killing) viruses are in varying stages of development, including modificati...
