Big news in iPS cell transplants


iPS cell-derived retinal cells have been successfully transplanted from one monkey to another without need of immunosuppressant drugs.

Mathematical model predicts self-organized learning in real neurons


The free energy principle predicted how real neural connections changed as neurons “learned” in a dish.

Summer fun: how plants beat the heat


Scientists have discovered a gene that allows plants to cope with extreme heat by changing the composition of chloroplast membranes.

Brain wave synchrony can predict memory age


The degree of neuronal synchrony between the anterior cingulate cortex and the hippocampus during recall is an indication of memory age (in mice).

Smoker gut bacteria reduce bowel inflammation in ulcerative colitis


Mouth bacteria that settle in the guts of smokers activate helper T-cells that counter inflammation in ulcerative colitis.
