Scientists clone mice from adult skin stem cells

...em cells taken from skin can be used to clone mice using a procedure called nuclear transfer. The findings ...y scientists have focused so much attention toward using nuclear transfer, which would allow us to use adult stem cells from the same patient rather than tho...

Turning green gunk to gold, anti-cancer gold

... native blue-green algae for high-level production using traditional fermentation approaches," said Sherman. But the compound, called cryptophycin 1, held so much promise as an anti-cancer drug that organic chemists got busy trying to find ways to make a synthetic form of the compound in large enough quant...

Iowa State University botanists identify new species of North American bamboo

...plant ecologically. And there's recent interest in using it for re-vegetation projects because it's native ...volutionary family tree of bamboo species. They're using modern DNA sequencing technologies together with traditional plant taxonomy, which involves observat...

Yale biologists 'trick' viruses into extinction

...said senior author Turner. "We proved the concept using a non-human virus, and variants of the bacteria cells it infects." In ecology, a habitat that supports population growth is termed a "source," whereas a non-supportive habitat is a "sink." This study reported on the success of phi-6 virus populati...

Infection detectives use disease 'fingerprints' to track common infections in children

Scientists use nanoparticle to discover disease-causing proteins

...iology. "The problem with the current method of using proteomics - protein profiling - is that we use very small sample amounts so sensitive that we can't effectively use existing technologies to study them," Tao said. "In addition, to study a specific protein and its function, we want to preserve its n...

UW launches study testing adult stem cells for heart damage repair

...erapy - regenerative medicine - treats diseases by using growth factors, genes or stem cells to promote blood vessel or tissue growth," explains Amish Raval, head of cardiovascular regenerative medicine at UW Health. The goal with this approach, he says, is to promote either angiogenesis, which is the gr...

Scientists find method to pick noncompetitive animals, improve production

...ited and can be estimated. They also found that by using the new tool they were able to confirm two-thirds more inherited trait variations that impact social interactions than could be identified with classical selection analysis. "Now we have a tool to explain how species in nature evolved in response ...

Surgeons develop simpler way to cure atrial fibrillation

... is a clamplike instrument that heats heart tissue using radiofrequency energy. By holding areas of the heart within the jaws of the device, surgeons can create lines of ablation, or scar tissue, on the heart muscle. In the older Cox-maze III procedure, the lines of ablation were made by cutting the heart ...

Destructive enzyme shows a benevolent side

... forms of the enzyme. They then stressed the cells using the chemical arsenite, a relative of arsenic. The investigators found that during stress, the enzyme interacts directly with another protein called TIA-1, a key protein involved in assembling stress granules. This interaction draws the enzyme-mRNA...

Protein discovery targets antibiotic-resistant bacteria

... “It’s basic science that we are doing, but we’re using that as a foundation for trying to develop approaches that will have positive impacts on human health,?says Dr. Martin....
