In this episode, we hear about a possible link between mitochondrial DNA and personality, why humans are mostly right-handed, circadian clocks and sunflowers, hairless mammals, and how some herbivores deal with plant toxins.
The circadian clock may help to control the development patterns which allow the florets on a sunflower head to go through their final stages of maturation at precisely the right time.
The ability of the adult zebrafish to replace damaged nephrons in the kidney depends on renal progenitor cells and renal interstitial cells working closely together.
A new method allows researchers to automatically assign cells into different cell types and tissues, a step which is critical for understanding complex organisms.
Experiments on mice suggest that an approach called antisense oligonucleotide therapy may be able to treat some symptoms of Angelman syndrome, including problems with epilepsy and sleep.
