Principles of limb regeneration in salamanders show link to mammals

01-Oct-2018

Scientists have long argued over which cells enable salamanders to grow back lost limbs. By tracking lineages and characterising individual cells, researchers could now show that connective tissue cells develop stem-cell-like properties and underlie the regeneration of legs. Among all four-legged ...

How millions of neurons become unique

27-Sep-2018

How is it possible that so many different and highly specific neurons arise in the brain? A mathematic model developed by researchers from the University of Basel’s Biozentrum demonstrates that different variants of genes enable such a random diversity. The scientists describe in “Cell Reports” ...

Better protection of the eye from glaucoma

30-May-2018

Under the increased pressure of glaucoma, scientists want to help the neurons in our eyes better protect themselves and get better help from their friends. They are working to see whether agents that activate the innate neuron protector sigma 1 receptor, or S1R, can do both. Current glaucoma ...

Identifying rapid neuromodulation of interneurons in human neocortex

30-Apr-2018

The human neocortex mediates many of the capacities that distinguish us from our closest relatives such as conscious thought and language. It is therefore striking that our understanding of this brain area is still overwhelmingly based on studies with animal models. A team of scientists led by ...

Stem cell divisions in the adult brain seen for the first time

12-Feb-2018

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life. The generation of new nerve cells was once ...

New insights into how your brain keeps its balance

23-Jan-2018

As with all things in life, healthy brain function depends on a balance of forces. We think of our brains as active - moving a leg and saying a word are all "active" events. But it is just as important for our brains to be able to stop these actions -to stop our leg, and to stop our speech. But ...

Selenium Protects a Specific Type of Interneurons in the Brain

Scientific ‘by-catch‘ solves decades-old mystery

03-Jan-2018

200 years after the discovery of the trace element selenium, researchers at Helmholtz Zentrum München have shown for the first time why this chemical element is indispensable for mammalian life. As integral part of the enzyme GPX4, selenium protects a subset of neurons from cell death during ...

Protein-folding simulations sped up

08-Dec-2017

Proteins, the ubiquitous workhorses of biochemistry, are huge molecules whose function depends on how they fold into intricate structures. To understand how these molecules work, researchers use computer modeling to calculate how proteins fold. Now, a new algorithm can accelerate those vital ...

3-D axon assemblies pave the way for drug discovery

30-Oct-2017

Axons are the structures through which neurons transmit information to other cells. In the body, they aggregate to form fascicles. Several technologies allow scientists to generate and study single axons in the lab, but none are effective at creating nerve fascicles. A collaboration between ...

Circular RNA linked to brain function

16-Aug-2017

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders. While hundreds ...
