New work shows that histones, long treated as boring spools for DNA, sit at the center of the origin story of eukaryotes and continue to play important roles in evolution and disease.
Glycans, the complex sugars that stud cellular surfaces, are like a language that life uses to mediate vital interactions. Researchers are learning how to read their meaning.
Unusual proteins that can quickly fold into different shapes provide cells with a novel regulatory mechanism.
Inside cells, droplets of biomolecules called condensates merge, divide and dissolve. Their dance may regulate vital processes.
The simple insight that most changes are random had a profound effect on genetics, evolution and ecology.
Even genes essential for life can be caught in an evolutionary arms race that forces them to change or be replaced.
Emmanuelle Charpentier and Jennifer Doudna have been awarded the 2020 Nobel Prize in Chemistry for their development of CRISPR/Cas9 genetic editing.
