Current human embryonic stem cell lines contaminated UCSD/Salk team finds

...issue because this opens up the idea thatmetabolic transfer of glycans is occurring between cells," said Gage."Also, components of the growth medium have the capacity to change theimmunological characteristics of the human ES cells. More research isneeded to understand the optimal conditions for preparing hum...

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

...tematic study of relatively recent horizontal gene transfer into a protist, scientists report evidence in the DNA sequence that E. histolytica likely picked up a significant number of its metabolic genes from bacterial co-inhabitants of the human gut. Identification of these genes sheds new light on the unusu...

Timing is everything: First step in protein building revealed

... phenomenon, known asfluorescence resonance energy transfer or FRET, to monitor therelationship between eIF1 and its relative as the ribosome complexassembled and after RNA was added to the mix."We weren't even sure the two fluorescent molecules would be closeenough together to create a FRET signal at all," s...

New Technique for Tracking Gene Regulators

Researchers reveal the infectious impact of salmon farms on wild salmon

...e UK's national academy of science) shows that the transfer of parasitic sea lice from salmon farms to wild sa... believed. This quantitative analysis of parasite transfer is a scientific milestone in a contentious debate. It is the first to isolate and measure the impact...

Scientists identify genetic pathways essential to RNA interference

...logical research. The process interrupts the usual transfer of instructions from double-stranded DNA, through single-stranded messenger RNA and finally into proteins. Short, double-stranded pieces of RNA bind to the complementary messenger RNA segments, shutting down gene expression. RNAi occurs naturally in ...

Papers of DNA Pioneer and Nobel Laureate Francis Crick Added to National Library of Medicine’s Profiles in Science Web Site

...ick’s unpublished note predicting the existence of transfer ribonucleic acid. Profiles in Science was launched September 1998 by the National Library of Medicine. The Library, the world’s largest library of the health sciences, is a component of the National Institutes of Health, U.S. Department of Health an...

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

...bird droppings. On islands without foxes, seabirds transfer nutrients from the ocean to the land by feeding on marine fish and invertebrates and spreading nutrient-rich guano around the islands. Add foxes, and the indirect effects on the whole ecosystem are as dramatic as the direct effects on the seabirds. ...

Nano-Probes Allow an Inside Look at Cell Nuclei

...sed on their size, they can be used to observe the transfer of material between cells. "We can have two different quantum dots in two different cells, and watch as the cells exchange their mitochondria," says Chen, adding that their technique paves the way for imaging a host of other long-term biological eve...

First real-time view of developing neurons reveals surprises, say Stanford researchers

...ll connect to other neurons and form synapses that transfer information. As the neuron matures, some of these branches form stable synapses while others recede. This trial-and-error process is what establishes the final interconnected mesh of the brain. Because the group could see the full branching structur...

NJIT Presidential Award winner takes stem cell research another step

... in another. Researchers originally thought such a transfer might be rejected. And it's not just defective bones that may be regenerated by stem cells. Arinzeh is now testing biomaterials that, in combination with stem cells, might also repair cartilage, tendon and neuronal tissues. Her studies could lead to...

Computational Method Speeds Mapping of Cell Signaling Networks

... A and B, it can detect whether B depends on A for transfer of the signal. The team's analysis predicted all but three of 18 well-studied T-cell network relationships. Although the work was largely a "proof of principle" report designed to demonstrate the usefulness of their method, their studies also identi...

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

...n the new MFC, when the bacteria eat biomass, they transfer electrons to an anode. The bacteria also release protons, hydrogen atoms stripped of their electrons, which go into solution. The electrons on the anode migrate via a wire to the cathode, the other electrode in the fuel cell, where they are electroch...

First frozen egg baby born in Canada

... at the McGill Reproductive Centre have had embryo transfer produced from vitrified eggs, resulting in 7 pregnancies including this livebirth. "The results are particularly encouraging because this success rate is comparable to regular IVF cycles with ICSI using fresh eggs in many IVF centres," says Dr. Tan. ...
