Cells grow more naturally in 'spaghetti'

The usual way of cultivating cells is to use a flat laboratory dish of glass. However, inside a human body, the cells do not grow on a flat surface, but rather in three dimensions. This has lead researchers at Lund University ...

Nanoparticle screen could speed up drug development

Many scientists are pursuing ways to treat disease by delivering DNA or RNA that can turn a gene on or off. However, a major obstacle to progress in this field has been finding ways to safely deliver that genetic material ...

Immune system defence force captured in action

How the natural defence force within our immune system attacks and destroys harmful invaders such as virus-infected and cancerous cells has been visualised in microscopic detail by scientists from UCL, Birkbeck, University ...

Nanoparticles hitchhiking their way along strands of hair

In shampoo ads, hair always looks like a shiny, smooth surface. But for physicists peering into microscopes, the hair surface looks much more rugged, as it is made of saw-tooth, ratchet-like scales. In a new theoretical study ...

New stem cell technique shows promise for bone repair

A recent study, affiliated with UNIST has developed a new method of repairing injured bone using stem cells from human bone marrow and a carbon material with photocatalytic properties, which could lead to powerful treatments ...
