Phys.org / A protein thought to play a supporting role in DNA replication actually facilitates the whole process

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its code and build new strands. ...

Phys.org / Superfluids are supposed to flow indefinitely. Physicists just watched one stop moving

Ordinary matter, when cooled, transitions from a gas into a liquid. Cool it further still, and it freezes into a solid. Quantum matter, however, can behave very differently. In the early 20th century, researchers discovered ...
