Enhancing the chemistry of zinc

(Phys.org) -- By tinkering with a zinc molecule, Virginia Commonwealth University researchers have discovered it can exist in a higher oxidation state, opening the door for a new form of chemistry and new composition of matter.

We need to talk: How cells communicate to activate notch

During formation of multi-cellular organisms, cells need to talk to each other to make critical decisions as to what kind of cell to become, as well as when and where to become that cell type. The Notch signaling system allows ...

Copy of the genetic makeup travels in a protein suitcase

Scientists from the Institute for Physical and Theoretical Chemistry at the University of Bonn have succeeded for the first time in the real time filming of the transport of an important information carrier in biological ...

Organic carbon from Mars, but not biological

(Phys.org) -- Molecules containing large chains of carbon and hydrogen--the building blocks of all life on Earth--have been the targets of missions to Mars from Viking to the present day. While these molecules have previously ...

Keeping track to selenium metabolism

Spanish and Danish researchers have developed a method for the in vivo study of the unknown metabolism of selenium, an essential element for living beings. The technique can help clarify whether or not it possesses the anti-tumour ...

Proteins shine a brighter light on cellular processes

Scientists have designed a molecule which, in living cells, emits turquoise light three times brighter than possible until recently. This improves the sensitivity of cellular imaging, a technique where biological processes ...
