Giant phage CRISPR-CasΦ is a hyper-compact genome editor

Compact defense system in bacteriophages The CRISPR-Cas system, which occurs naturally in many prokaryotes, is often used to manipulate the genome. CRISPR arrays in the bacterial genome, which originate from the genome of invading viruses, are used to generate a CRISPR-RNA, which leads the Cas enzyme to destroy repeated viral invaders. An unexpectedly compact CRISPR-Cas system has recently been identified …

China publishes genome data for the corona virus in Beijing, officials suggest a European strain

BEIJING (Reuters) – China has released genome sequencing data for the coronavirus responsible for a recent outbreak in Beijing. Officials said on Friday it had identified a European tribe based on preliminary studies. China, which had been under pressure to release the data sooner than later when COVID-19 cases appeared in the country’s capital, said it had also submitted the …

Like film editors and archaeologists, biochemists put genome history together

Figure 1 shows the dynamics that researchers see in the intron of group II compared to the spliceosome. The figure shows that both splicing machines experience an identical 90 degree rotation of an important area during splicing. Picture credits: Daniel Haack Hollywood editors of the old school cut unwanted movie images and patched into the images they wanted to make …

The ownership of a dog is influenced by our genome – ScienceDaily

A team of Swedish and British scientists has studied the heritability of dog ownership using information from 35,035 twin pairs from the Swedish Twin Registry. The new study suggests that genetic variation accounts for more than half of the variation in dog ownership, implying that the choice of having a dog is strongly influenced by a person's genetic makeup. Dogs …

Scientists create E. coli with fully synthetic genome

E. coli Image: IDKlab (Wikimedia Commons) Scientists created a variant of E. coli bacteria with a fully synthetic genome, according to a new publication. Construction and replacement of the entire genome was just one of the aims of the team at the Molecular Biology Laboratory of the Cambridge, UK Medical Research Council. They hoped that the resulting bacteria would use …

Pioneer Human Genome Project strives to find healing for sick sons

Editor's Note: Ryan Prior is a cross-platform associate producer with CNN. In 2007 he was diagnosed with a chronic fatigue syndrome and wrote about this experience here. SAN FRANCISCO – Several times a day, Ron Davis sits with his head bowed, waiting in front of his son's bedroom for a subtle signal that it's okay to come in. He opens …
