Our circadian clocks play a crucial role in our health and well-being, keeping our 24-hour biological cycles in sync with light and dark exposure. Disruptions in the rhythms of these clocks, as with jet lag and daylight saving ...
Researchers at University of Tsukuba have identified a photophobic response (light avoidance) in the unicellular apusomonad Podomonas kaiyoae. The study provides critical insight into the evolution of complex flagellar and ...
Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that drives constant evolution. ...
Researchers at the School of Biological Sciences of The University of Hong Kong (HKU) have uncovered how eukaryotic cells can control gene activity even after losing one of their major gene-regulatory systems during evolution. ...
Scientists at the Max Planck Institute for Biology have discovered a remarkably streamlined strategy for developmental control in brown algae. They have shown that a single ARGONAUTE (AGO) protein orchestrates the transition ...
Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) ...
Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles such as mitochondria and cell nuclei, recent studies have also revealed organelles without membranes. ...
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. ...
Researchers at Forschungszentrum Jülich and Heinrich Heine University Düsseldorf have developed a tool that could significantly transform genome research: Helixer identifies genes directly from DNA sequences—without laboratory ...
It's Saturday! This week, in an eminently practical analysis of the Boltzmann brain conjecture, physicists put constraints on the idea that memories could arise from random fluctuations in entropy rather than reflecting the ...
