Self-healing DNA nanostructures

DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine. However, these intriguing structures don't persist long in biological ...

Location is everything for plant cell differentiation

While the fate of most human cells is determined by their lineage—for example, renal stem cells go on to form the kidney while cardiac progenitor cells form the heart—plant cells are a little more flexible. Research shows ...

Tiny light-up barcodes identify molecules by their twinkling

An imaging technique developed at Duke University could make it possible to peer inside cells and watch dozens of different molecules in action at once—by labeling them with short strands of light-up DNA that blink on and ...

New method gives microscope a boost in resolution

Scientists at the University of Würzburg have been able to boost current super-resolution microscopy by a novel tweak. They coated the glass cover slip as part of the sample carrier with tailor-made biocompatible nanosheets ...

How skin cells protect themselves against stress

The skin is our largest organ, and, among other things, it provides protection against mechanical impacts. To ensure this protection, skin cells have to be connected to one another especially closely. Exactly how this mechanical ...

Tiny lasers light up immune cells

A team of researchers from the School of Physics at the University of St Andrews have developed tiny lasers that could revolutionise our understanding and treatment of many diseases, including cancer.

Novel quantum dots enhance cell imaging

A team of researchers from the University of Illinois at Urbana-Champaign and Mayo Clinic have engineered a new type of molecular probe that can measure and count RNA in cells and tissue without organic dyes. The probe is ...
