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 ...

Tiny biomolecular tweezers studying force effect of cells

A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices—too small to see without a microscope—use opposing magnetic and ...

Study reveals new insights into sulfate-reducing bacteria

(Phys.org) —Sulfate-reducing bacteria are common in oxygen-deprived habitats, and they can have harmful industrial and health effects as well as beneficial environmental effects. This study examines the biochemical pathways ...

Probing hydrogen catalyst assembly

Biochemical reactions sometimes have to handle dangerous things in a safe way. New work from researchers at UC Davis and Stanford University shows how cyanide and carbon monoxide are safely bound to an iron atom to construct ...

New discoveries show biological formation of oxygen in soils

In the 1930s, the ability of green plants to form oxygen through oxidation of water–photosynthesis was discovered. Since then, no other large-scale biological formation of oxygen has been found, until now. New research ...

Scientists identify 'molecular fossil' in fungi

(Phys.org) —All but a few eukaryotes die without oxygen, and they respond dynamically to changes in the level of oxygen available to them. UCD scientists used genetic analysis to pinpoint an evolutionary switch in regulating ...
