Plant Research Reveals Unexpected Function for Key Cellular Protein

A cell protein previously believed only to provide a scaffolding for DNA has also been shown to directly influence DNA transcription into RNA – the first step of the process by which an organism's genetic code expresses itself. The fundamental breakthrough was discovered in apple cells but is relevant to all living organisms made of nucleus-containing cells, including humans.

ALS Stem Cell Model Reveals Increased Susceptibility to Cell Death

Amyotrophic lateral sclerosis (ALS) is a fast-progressing neurodegenerative disease with an average survival time of three years. In ALS, certain types of neurons called motor neurons that are required for muscle contractions die off, leading to progressive paralysis affecting most muscles of the body. The molecular causes of ALS are poorly understood, and effective treatments are missing.
