DNA nanotechnology places enzyme catalysis within an arm's length

Using molecules of DNA like an architectural scaffold, Arizona State University scientists, in collaboration with colleagues at the University of Michigan, have developed a 3-D artificial enzyme cascade that mimics an important ...

New method of incorporating fluoride into drugs

(Phys.org) —Synthetic biology is a science that aims to harness natural biological processes for other uses, such as in the manufacture of fuels and drugs. Now, synthetic biology researchers in the U.S. have developed a ...

Chemists discover cannabis 'pharma factory'

University of Saskatchewan researchers have discovered the chemical pathway that Cannabis sativa uses to create bioactive compounds called cannabinoids, paving the way for the development of marijuana varieties to produce ...

Mechanism for regulating plant oil production identified

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have identified key elements in the biochemical mechanism plants use to limit the production of fatty acids. The results suggest ways scientists ...

Mice (and possibly humans) make their own morphine

(PhysOrg.com) -- New research has confirmed that mice have the biochemical pathways required to manufacture morphine from intermediates. Morphine is a powerful drug usually derived from the opium poppy, but scientists have ...

RNA interference found in budding yeasts

Some budding yeast species have the ability to silence genes using RNA interference (RNAi). Until now, most researchers thought that no budding yeasts possess the RNAi pathway because Saccharomyces cerevisiae, the protoypical ...

Methane-producing microorganism makes a meal of iron

A new understanding of how an important methane-producing microorganism creates methane and carbon dioxide could eventually allow researchers to manipulate how much of these important greenhouse gases escape into the atmosphere. ...
