New insight into mammalian stem cell evolution

The genes regulating pluripotent stem cells in mammals are surprisingly similar across 48 species, Kyoto University researchers report in the journal Genome Biology and Evolution. The study also shows that differences among ...

Evolutionary conflicts predicted

Evolution seems to be an unpredictable process. However, predicting the constraints of evolution is possible. Researchers from AMOLF and the French ESPCI have demonstrated this using their mathematical method, followed by ...

The tug-of-war at the heart of cellular symmetry

Symmetry and asymmetry are fundamental properties of nature. Seen from above, butterflies have left-right symmetry, while male fiddler crabs show dramatic asymmetry. This is also the case for the fundamental units of life: ...

Modeling neuronal cultures on 'brain-on-a-chip' devices

For the past several years, Lawrence Livermore National Laboratory (LLNL) scientists and engineers have made significant progress in development of a three-dimensional "brain-on-a-chip" device capable of recording neural ...

Researchers develop the 'ultimate cell sorter'

In medicine and biology, there is great interest in efficient and inexpensive methods for identifying and separating different cell types, for example for medical diagnostics or for regenerative therapies using stem cells. ...

Changes in cellular degradation hubs can lead to cancer

Cancer cells grow and divide in an uncontrolled manner. A new study from Uppsala University now shows how alterations in a cell's degradation hubs, called lysosomes, can cause abnormal cell growth. The results are published ...
