Regulation of an embryonic small heat shock protein deciphered

Small heat shock proteins ensure that other proteins do not clot, allowing the cell to survive stress. Defects in these "small helpers" are associated with medical conditions like cataracts and cancer. Now, scientists at ...

Making composite material smart with precious metal

Doping polymer brushes with gold nanoparticles results in a switchable composite material which changes its thickness depending on the pH value. The research by physicists at the TU Darmstadt, published in the journal Soft ...

Self-assembled nanostructures can be selectively controlled

Plasmonic nanoparticles exhibit properties based on their geometries and relative positions. Researchers have now developed an easy way to manipulate the optical properties of plasmonic nanostructures that strongly depend ...

When toxins preserve populations

Some soil bacteria can alter their environment in such a way as to endanger their own survival – unless, that is, toxins do not impede their growth beforehand.

Measuring optimally with spheres

Bio-reactors are the cooking pots of biochemists and bio-technologists, in which pharmaceutical agents, enzymes or nematodes are produced for the purpose of biological pest control. A nutrient solution (such as heat, oxygen, ...
