Making blood-sucking deadly for mosquitoes

Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a UA team of biochemists found.

New tasks attributed to Aurora proteins in cell division

(PhysOrg.com) -- When a cell divides, the genetic information in the chromosomes must be passed on error-free to the daughter cells. Researchers at the Friedrich Miescher Laboratory in Tübingen are studying this process ...

Oxygen key to 'cut and paste' of genes

(PhysOrg.com) -- An oxygen-sensitive enzyme has been found to play a key role in how genes create the many different proteins that make up our bodies.

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, ...

Body clock regulates metabolism

(PhysOrg.com) -- UC Irvine researchers have discovered that circadian rhythms - our own body clock - regulate energy levels in cells. The findings have far-reaching implications, from providing greater insights into the bond ...

'Promiscuous' enzymes still prevalent in metabolism

Open an undergraduate biochemistry textbook and you will learn that enzymes are highly efficient and specific in catalyzing chemical reactions in living organisms, and that they evolved to this state from their "sloppy" and ...
