Quantum dots spotlight DNA-repair proteins in motion

Repair proteins appear to efficiently scan the genome for errors by jumping like fleas between DNA molecules, sliding along the strands, and perhaps pausing at suspicious spots, say researchers at the University of Pittsburgh, the University of Essex and the University of Vermont who tagged the proteins with quantum dots to watch the action unfold.

Can we detect quantum behaviour in viruses?

The weird world of quantum mechanics describes the strange, often contradictory, behaviour of small inanimate objects such as atoms. Researchers have now started looking for ways to detect quantum properties in more complex and larger entities, possibly even living organisms.

Molekulare Lichtschalter

Molekuele, die erst bei Bestrahlung mit Licht ihre biologische Funktion entfalten, koennten an genau definierter Stelle im Organismus 'angeschaltet' werden. Wissenschaftlern vom Leibniz-Institut fuer Molekulare Pharmakologie (FMP) und von der Technischen Universitaet Berlin ist es gelungen, solche lichtsensiblen molekularen Strukturen zu entwickeln.
