Science study holds implications for gene therapy and stem cell biology

...ntire blood system, as in leukemia treatment. The process has the potential to treat inherited blood disorders, as demonstrated in an increasing number of patients. The new study published in Science suggests that enhanced fitness of stem cells could be a welcome side effect of current gene-based therapies,...

Innovative collaboration brings Arctic science into the classroom

...thing. If they realize that science is an exciting process as opposed to a bunch of boring facts to memorize from textbooks, then this program will have been a tremendous success." In addition to his work with TREC in the Arctic, Holmes has taken other opportunities to creatively connect science and educati...

Software Tool for Converting Scientific Text into a Database of Functional Relationships

...tion extraction technology that would help them to process literature, patent applications and internal text documents in order to create and automatically maintain internal functional relationship databases, amenable to computational analysis," said Nikolai Daraselia, Director of Research at Ariadne Genomic...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...nisms have to mutate, so they turn on the mutation process when they are threatened with extinction. Romesberg reasoned that since mutations can be turned on full-force, perhaps they could be shut off as well. Doing so, he says, would put a halt to evolution -- an interesting prospect because the mutations ...

...esulting offspring would be 50 percent Churro. The process would be repeated using a female offspring, making the next generation 75 percent Churro. They keep doing this until the sheep are 93 percent Churro. The collection could also be used by breeders or researchers to introduce genetic variation into ex...
