The light-bending dance of binary black holes  

A pair of orbiting black holes millions of times the Sun's mass perform a hypnotic pas de deux in a new NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas - called an accretion disk - that surrounds each one.

Good dental health may help prevent heart infection from mouth bacteria  

Good oral hygiene and regular dental care are the most important ways to reduce risk of a heart infection called infective endocarditis caused by bacteria in the mouth. There are four categories of heart patients considered to be at highest risk for adverse outcomes from infective endocarditis, and only these patients are recommended to receive preventive antibiotic treatment prior to invasive dental procedures.

The architect of genome folding  

The DNA molecule is not naked in the nucleus. Instead, it is folded in a very organized way by the help of different proteins to establish a unique spatial organization of the genetic information. This 3D spatial genome organization is fundamental for the regulation of our genes and has to be established de novo by each individual during early embryogenesis. Researchers now reveal a yet unknown and critical role of the protein HP1a in the 3D genome re-organization after fertilization. The study

With fossils few and far between, paleontologists have shied away from estimating the size of extinct populations. But UC Berkeley scientists decided to try, focusing on the North American predator T. rex. Using data from the latest fossil analyses, they concluded that some 20,000 adults likely roamed the continent at any one time, from Mexico to Canada. The species survived for perhaps 2.5 million years, which means that about 2.5 billion lived and died overall.

Those who did not have COVID-19 did not have a full immune response until after receiving their second vaccine, reinforcing the importance of the two recommended doses.

Technique allows mapping of epigenetic information in single cells at scale  

Histones are tiny proteins that bind to DNA and hold information that can help turn on or off individual genes. Researchers have developed a technique that makes it possible to examine how different versions of histones bind to the genome in tens of thousands of individual cells simultaneously. The technique was applied to the mouse brain and can be used to study epigenetics at a single-cell level in other complex tissues.
