Cas9 is part of the CRISPR genetic defense system in bacteria, which scientists have been harnessing to edit DNA in animals, plants and even human cells. In this case, Emory researchers are using Cas9 to put a clamp on RNA, which hepatitis C virus uses …

The study, published today in Nature Methods, has experimentally established for the first time that when a cell loses or gains a copy of a chromosome during cell division, the genes in that particular region of DNA show decreased or increased expression.

We read a lot of weirdness every day and it’s hard not to become jaded even to the most Fortean of mysteries we’ve heard variations of over and over again, but this is something entirely new and to put it simply, it blows our minds. Researchers have absolutely no idea what caused the fairy circles […]

Scientists from South Carolina's leading public universities—the University of South Carolina and Clemson University—have made a discovery that could dramatically improve the efficiency of batteries and fuel cells. The research, which is published in …

CTCs were enumerated by CellSearch then purified by immunomagnetic EpCAM enrichment and fluorescence-activated cell sorting. Targeted ion semiconductor sequencing was performed on whole genome-amplified DNA from CTCs, tumor specimens, and …

Sergeant Richard Evans, 46, was dismissed by South Wales Police for ‘disgraceful’ sexual behaviour towards women in custody – and against his own colleagues in the police force.

The idea of bringing extinct animals back to life continues to reside in the realm of science fiction. But scientists have taken a small step closer to that goal, by inserting the DNA of a woolly mammoth into lab-grown elephant cells. Harvard …

According to a report published by Popular Science on March 24, the team used a piece of equipment called CRISPR (clustered regularly interspaced short palindromic repeats) to pull 14 pieces of DNA from the woolly mammoth and insert them into a tissue …

Using a DNA editing tool called CRISPR, the scientists spliced genes for the mammoths' small ears, subcutaneous fat, and hair length and color into the DNA of elephant skin cells. The tissue cultures represent the first time woolly mammoth genes have …

For the first time in over 3,000 years, the functional components of wooly mammoth DNA have been brought to life (albeit in a petri dish). The achievement represents an important step towards potential efforts to bring the extinct species back. The …
