The underlying mechanisms of 3D tissue formation

27-Nov-2018

If you want to build an organ, such as for transplant, you need to think in 3D. Using stem cells, scientists for some time have been able to grow parts of organs in the lab, but that is a far cry from constructing an actual, fully-formed, functioning, three-dimensional organ. For students of ...

A more effective hydrogel for healing wounds

22-Nov-2018

Researchers at the University of New Hampshire have created an easy-to-make, low-cost injectable hydrogel that could help wounds heal faster, especially for patients with compromised health issues. Wound healing can be complex and challenging, especially when a patient has other health obstacles ...

3D 'organ on a chip' could accelerate search for new disease treatments

30-Oct-2018

Researchers have developed a three-dimensional 'organ on a chip' which enables real-time continuous monitoring of cells, and could be used to develop new treatments for disease while reducing the number of animals used in research. The device, which incorporates cells inside a 3D transistor made ...

Restoring tissue with inspiration from plants and animals

20-Mar-2018

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering have developed new wound dressings that dramatically accelerate healing and improve tissue regeneration. The two different types of nanofiber ...

Immortal cells for tailor-made active substances

12-Mar-2018

When scientists discover a new active substance, e.g. for use against a pathogen, they usually study its exact effect in cultured cells. But there is a lack of suitable test systems that simulate body tissues, because cells rapidly lose their specific properties once they are away from their ...

Silk fibers could be high-tech 'natural metamaterials'

05-Feb-2018

New research has demonstrated how the nano-architecture of a silkworm's fiber causes "Anderson localization of light," a discovery that could lead to various innovations and a better understanding of light transport and heat transfer. The discovery also could help create synthetic materials and ...
