Stepwise Earth oxygenation is an inherent property of global biogeochemical cycling
Oxygenation of Earth's atmosphere and oceans occurred across three major steps during the Paleoproterozoic, Neoproterozoic, and Paleozoic eras, with each increase having profound consequences for the biosphere. Biological or tectonic revolutions have been proposed to explain each of these stepwise increases in oxygen, but the principal driver of each event remains unclear. Here we show, using a t

DNA loop extrusion by human cohesin
Eukaryotic genomes are folded into loops and topologically associating domains, which contribute to chromatin structure, gene regulation, and gene recombination. These structures depend on cohesin, a ring-shaped DNA-entrapping adenosine triphosphatase (ATPase) complex that has been proposed to form loops by extrusion. Such an activity has been observed for condensin, which forms loops in mitosis,

Human cohesin compacts DNA by loop extrusion
Cohesin is a chromosome-bound, multisubunit adenosine triphosphatase complex. After loading onto chromosomes, it generates loops to regulate chromosome functions. It has been suggested that cohesin organizes the genome through loop extrusion, but direct evidence is lacking. Here, we used single-molecule imaging to show that the recombinant human cohesin-NIPBL complex compacts both naked and nucle

Imaging stress and magnetism at high pressures using a nanoscale quantum sensor
Pressure alters the physical, chemical, and electronic properties of matter. The diamond anvil cell enables tabletop experiments to investigate a diverse landscape of high-pressure phenomena.

How Far Are We from (Accurately and Safely) Editing Human Embryos?
We can already edit genes in human embryos. We can even do it in a way to pass the edits down generations, fundamentally changing a family's genetic makeup. Doing it well, however, is far more difficult. It's impossible to talk about human germline genome editing without bringing up the CRISPR baby fiasco . Over a year ago, a rogue Chinese scientist performed an edit on fertilized human embryos t

Survey Finds That Water Is Common Around Exoplanets
Yeah, Got That Water After surveying 19 exoplanets, a University of Cambridge-led research team found 14 had water vapor in their atmospheres — more than they'd expected. The amount of water vapor, meanwhile? Less than they'd anticipated. Yet: These new insights could go a long way toward narrowing our hunt for extraterrestrial life.
