Having an eye for colors: Printable light sensors

Cameras, light barriers, and movement sensors have one thing in common: They work with light sensors that are already found in many applications. In future, these sensors might also play an important role in telecommunications, ...

Molecular motors direct the fate of stem cells

Scientists at the University of Groningen and the University Medical Center Groningen used molecular motors to manipulate the protein matrix on which bone marrow-derived mesenchymal stem cells are grown. Rotating motors altered ...

Artificial cells act more like the real thing

Protocells—artificial cells—that are active and mimic living cells by moving independently and that are biocompatible and enzymatically active are now possible using an improved method developed by Penn State researchers.

Collagen fibers encourage cell streaming through balancing act

Collagen is the most abundant protein in mammals, making up skin, bone, tendons and other soft tissues. Its fibrous nature helps cells to move throughout the body, but until now, it wasn't clear how the length of fibers influences ...

Mapping the energetic landscape of solar cells

A new spectroscopic method now makes it possible to measure and visualize the energetic landscape inside solar cells based on organic materials. It was developed by a research team led by Prof. Dr. Yana Vaynzof, a physicist ...

How bird feather patterns form

Feathers evolved in dinosaurs and are a key characteristic of birds today. They are arranged in a precise hexagonal pattern in a bird's skin, but it has been unclear how this happens. According to a new study published February ...
