Chemists have succeeded in specifically controlling the setup of precision polymers by light-induced chemical reactions. The new method allows for the precise, planned arrangement of the chain links, i.e. monomers, along polymer chains of standard length.
Researchers have been able to generate multifunctional RNA nanoparticles that could overcome treatment resistance in breast cancer, potentially making existing treatments more effective in these patients.
When most living creatures get hurt, they can self-heal and recover from the injury. But, when damage occurs to inanimate objects, they don't have that same ability and typically either lose functionality or have their useful lifecycle reduced. Researchers are working to change that.
Scientists have discovered half-quantum vortices in superfluid helium. This vortex is a topological defect, exhibited in superfluids and superconductors, which carries a fixed amount of circulating current.
Our bodies contain Natural Killer (cells - an army that stops cancers and viruses before they can make us sick. A researcher has created a nanoparticle that increases the number of these killers 10,000-fold in the lab and her new technology has generated a licensing agreement that is expected to accelerate the therapy's path to clinical trials.
A newly funded project plans to gain new insights into the catalytic abilities of nanoparticles, particularly how the size, shape and chemical state of the particles change during a catalytic reaction.
