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.

Unraveling the Evolutionary Trajectories of Early Eukaryotes

Advanced tools and expanded fossil datasets have painted a clearer picture of the eukaryotic diversity of the Proterozoic eon, which has been hard to quantify. The findings show that Earth's severe Cryogenian glaciations catalyzed a pivotal shift in the evolution and diversity of early eukaryotes during this eon, 2500 to 538 million years ago.

Chaperone Proteins Unveil Their Role in Neurotransmission

A team of researchers from the University of Massachusetts Amherst is the first to show how proteins called "chaperones" are vital in ensuring that neurons can transmit signals to one another. When this neurotransmission breaks down, devastating diseases such as Alzheimer's and Parkinson's along with many others, can occur.
