Science, such a sweet mystery

I have been teaching and doing research at the university level for more than 40 years, which means that for more than four decades, I have been participating in a deception - benevolent and well intentioned, to be sure, ...

New mechanism discovered in meiosis

Inactivated, but still active– how modification of an enzyme governs critical processes in sexual reproduction.

Researchers take a fresh look at the Michaelis-Menten equation

Researchers from Aarhus University challenge one of the cornerstones of biochemistry, the Michaelis-Menten equation. They show that many enzymes in signaling pathways are independent of substrate concentration, because the ...

Fundamental discovery casts enzymes in new light

Just as a breeze causes leaves, branches and ultimately the tree to move, enzymes moving at the molecular level perform hundreds of chemical processes that have a ripple effect necessary for life. Protein complexes are often ...

Proteins prove their metal

(PhysOrg.com) -- The word 'metal' conjures up images of machines and heavy industry but metals are also intimately involved in the biological processes that regulate our bodies and underpin new energy technologies.

It takes a neutron beam to find a proton

Understanding the behavior of proteins and enzymes is key to unlocking the secrets of biological processes. The atomic structures of proteins are generally investigated using X-ray crystallography; however, the precise information ...
