Method to customize microbes for better biofuel production

Scientists at the US Department of Energy's Oak Ridge National Laboratory have demonstrated a method to insert genes into a variety of microorganisms that previously would not accept foreign DNA, with the goal of creating ...

Prevention of RNA virus replication

Researchers at Okayama University have successfully cleaved influenza viral RNA to prevent its replication using novel artificial RNA restriction enzymes in laboratory cell cultures. While further improvements are needed, ...

Identifying sloth species at a genetic level

Identifying species, separating out closely related species and managing each type on its own, is an important part of any animal management system. Some species, like the two types of two-toed sloth, are so close in appearance ...

DNA construction software saves time, resources and money

DNA construction, also known as DNA cloning or recombinant DNA technology - among a host of other terms - is one of the principal tools of modern biotechnology, used for a wide variety of purposes, including genetic studies, ...

Newly found DNA catalysts cleave DNA with water molecule

Better tools for manipulating DNA in the laboratory may soon be possible with newly discovered deoxyribozymes (catalytic DNA) capable of cleaving single-stranded DNA, researchers at the University of Illinois say.

Climbing the ladder to longevity: Critical enzyme pair identified

Experiment after experiment confirms that a diet on the brink of starvation expands lifespan in mice and many other species. But the molecular mechanism that links nutrition and survival is still poorly understood. Now, researchers ...
