Laws to Protect Athletes from Concussion Dangers Has an Impact – According to this article, more than 2½ years after the laws to protect young athletes against the dangers of concussions went on the books, repeat concussions began to decline among high school athletes.
Inbreeding Impairs Reproductive Success – In this article, mating with a close relative, known as inbreeding, reduces human evolutionary fitness — measured by the ability to produce offspring.
Method to Accelerate Maturation of Neurons Derived from Stem Cells – This article reveals that hydrogel can be used as a scaffold for engineering artificial brain tissue and promotes the development of neurons.
Mutation Plus Sun Tanning (Really UV Exposure) Causes Skin Cancer – In this article, a group of scientists based at Cornell University now report that melanoma may arise from melanocyte stem cells (MCSCs), specifically, MCSCs that have become “melanoma competent” because they have accumulated a sufficient number of genetic mutations.
Naked Mole Rat Cells Have a Stable Epigenome that Resists iPSC Reprogramming – Researchers observed that the reprogramming efficiency of naked mole rat fibroblasts in response to OSKM was drastically lower than that of mouse fibroblasts.
Generation of a Motor Nerve Organoid with Human Stem Cell-Derived Neurons – According to this article, to build an organoid mimicking developing nerve tissue, researchers employed a strategy that allowed the neurons to follow the cell-intrinsic axon growth and fasciculation programs with minimal intervention.
