Amyotrophic Lateral Sclerosis (ALS, also known as Lou Gehrig’s Disease) motor neurons. The stem cells used to generate these motor neurons were induced Pluripotent Stem (iPS) cells made from the skin cells of an 83-year-old ALS patient. Via.
Water flea Daphnia atkinsoni. This specimen has a “crown of thorns,” a defensive trait induced in offspring only when the parents sense chemical cues released by one of their main predators, the tadpole shrimp Triops cancriformis. The water flea’s exoskeleton (exterior structure, green) and subcellular details within the organism (nuclei – tiny blue dots) are both visible. Via.
