In the beginning was the phase separation

Was a simple mechanism decisive for the origin of life?

25-May-2018

The question of the origin of life remains one of the oldest unanswered scientific questions. A team at the Technical University of Munich (TUM) has now shown for the first time that phase separation is an extremely efficient way of controlling the selection of chemical building blocks and ...

Designer cells: artificial enzyme can activate a gene switch

A new kind of chemistry in living organisms

24-May-2018

Complex reaction cascades can be triggered in artificial molecular systems: Swiss scientists have constructed an enzyme than can penetrate a mammalian cell and accelerate the release of a hormone. This then activates a gene switch that triggers the creation of a fluorescent protein. The findings ...

A new way to stimulate cellular recycling process

18-May-2018

Brown University researchers studying the biology of aging have demonstrated a new strategy for stimulating autophagy, the process by which cells rebuild themselves by recycling their own worn-out parts. In a study the researchers show that the approach increased the lifespans of worms and flies, ...

Tiny 'antenna' tweaked on cells

18-May-2018

Scientists at Johns Hopkins Medicine and the National Tsing Hua University in Taiwan say they have found a fast way to manipulate a cell's cilia, the tiny, fingerlike protrusions that "feel" and sense their microscopic environment. The experiments, performed in mouse cells, may advance ...

Tumor-like spheres help scientists discover smarter cancer drugs

16-May-2018

Cancer is a disease often driven by mutations in genes. As researchers learn more about these genes, and the proteins they code for, they are seeking smarter drugs to target them. The ultimate goal is to find ways to stop cancer cells from multiplying out of control, thereby blocking the growth ...

Who am I? How cells find their identity

02-May-2018

The research group of Alex Schier, Director of the Biozentrum, University of Basel, has investigated more closely how a single embryonic cell develops into a heart, nerve or blood cell. For the first time, the researchers have been able to reconstruct the developmental trajectories of individual ...

Tiny implants for cells are functional in vivo

21-Mar-2018

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of living zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, ...

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 ...

How to target a gene

Finding proteins important for plant development, DNA repair and gene targeting

08-Mar-2018

All living cells have invented mechanisms to protect their DNA against breaks during duplication and against damage by UV-light or chemicals. A team of biologists led by Prof. Dr. Ralf Reski from the Faculty of Biology of the University of Freiburg, Germany has now found that members of the RecQ ...

Cells communicate in a dynamic code

Important intercellular communication encodes and transmits more than thought

20-Feb-2018

Multicellular organisms like ourselves depend on a constant flow of information between cells, coordinating their activities in order to proliferate and differentiate. Deciphering the language of intercellular communication has long been a central challenge in biology. Now, Caltech scientists ...
