Stem cells use signal orientation to guide division, study shows

Cells in the body need to be acutely aware of their surroundings. A signal from one direction may cause a cell to react in a very different way than if it had come from another direction. Unfortunately for researchers, such ...

Safe bioink for artificial organ printing

The development of biomaterials for artificial organs and tissues is an active area of research due to increases in accidental injuries and chronic diseases, along with the entry into a super-aged society. 3D bioprinting ...

Jekyll and Hyde corals tell different warming story

(Phys.org) —Like the rings of a tree trunk, Strontium-to-calcium ratios (Sr/Ca) in coral skeletons have been widely used to determine past ocean temperatures from yearly banded corals. However, scientists have now found ...

How random is stem cell development?

In just a few weeks a completely new organism develops from a fertilized egg cell. The real miracle is that a bunch of identical stem cells turns into completely different, specialized cell types. A team led by Christian ...

EGF growth factor accelerates cell division, study finds

Biologists at Heidelberg University have discovered new approaches for the treatment of cancer. They investigated how a special signalling molecule, the epidermal growth factor (EGF), stimulates the separation of chromosomes ...

Lighting the path for cells

ETH researchers have developed a new method in which they use light to draw patterns of molecules that guide living cells. The approach allows for a closer look at the development of multicellular organisms—and in the future ...

New machine learning technology explores circadian rhythms

We all have an internal clock but what makes us tick? Scientists at the Earlham Institute and IBM Research have developed new artificial intelligence (AI) and machine learning (ML) technology to understand how gene expression ...
