A team of MIT geochemists has unearthed new evidence in very old rocks suggesting that some of the first animals on Earth were likely ancestors of the modern sea sponge.
Just as life pulsates in big vibrant cities, it also prospers in crowded environments inside cells. The interior of cells is densely packed with biomolecules like proteins and nucleic acids. How is all this material distributed ...
An ambitious and revolutionary initiative aims to map every cell of all eukaryotic life on Earth. The result will be a Biodiversity Cell Atlas, which will reveal nature's secrets and help inform conservation efforts at a ...
A multinational research team has discovered a mysterious tubular structure—previously unknown in any organism—within Profftella, a symbiotic bacterium associated with a major global citrus pest. This discovery, made using ...
Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic material (chromosomes) equally, and then rebuild the nuclear envelope around the separated halves. ...
Turning genes on and off is like flipping a light switch, controlling whether genes in a cell are active. When a gene is turned on, the production of proteins or other substances is promoted; when it's turned off, production ...
A research team led by scientists from the Helmholtz Institute for RNA-based Infection Research (HIRI) has introduced a new way to fine-tune genetic material. Their study, published in Nature Biotechnology, describes an innovative ...
Coccolithophores are a type of single-celled microalgae that fix CO2 into organic matter and precipitate calcium carbonate, profoundly shaping ocean optics, carbon export, and long-term carbon storage. They are major contributors ...
If you pull an ice core from the outer edges of the Arctic polar cap, you might spot what looks like a faint line of dirt. Those are diatoms—single-celled algae with outer walls made of glass. Their presence in ice isn't ...
Despite being made from a relatively simple set of building blocks, ribonucleic acid (RNA) has a broad array of complex responsibilities. From providing structure to carrying the instructions for regulating genes and translating ...
