DNA replication is the process whereby cells make an exact copy of their DNA before cell division. A key part of the intricate DNA replication machinery is a molecular motor called CMG, which has the vital task of separating ...
Scientists have discovered a parasite is behind a severe die-off of long-spined sea urchins across the Caribbean Sea, which has had devastating consequences for coral reefs and surrounding marine ecosystems.
"Every once in a while a book lands on your desk that changes the way you perceive the world you live in, a book that fundamentally challenges your understanding of human history." So began the blurb that came with this book. ...
A hitherto unknown mechanism for DNA folding is described in a study in Nature published by researchers from Karolinska Institutet and the Max Planck Institute for Biophysics. Their findings provide new insights into chromosomal ...
Many common viruses responsible for childhood illnesses establish a home for life within us. This is evidenced in a new study carried out at the University of Helsinki and published in Nucleic Acids Research on March 23, ...
During a large-scale study of complex single-celled microbes, Dr. Christopher Bellas, Marie-Sophie Plakolb and Prof. Ruben Sommaruga from the Department of Ecology at the University of Innsbruck made an unexpected discovery. ...
At least five ice ages have befallen Earth, including one 635 million years ago that created glaciers from pole to pole.
In recent years, the microbiota—communities of microorganisms composed primarily of bacteria and fungi that are found in all eukaryotic organisms, including humans, animals and plants—has come into focus due to their contributions ...
Millions of years ago, the Earth was so cold that most of its surface was covered in ice. But that hard freeze might have been slushier than once thought.
Eukaryotes generate the energy for survival through cellular respiration in mitochondria by a process known as the oxidative phosphorylation. In this process, nutrients and oxygen are converted into a chemical form of energy: ...
