Cockroaches scurry around with thousands of pieces of bacterial genomes
Skip to content Transferring genes across species doesn’t just happen in microbes. Last week, we looked at a new study […]
The first complex cells had genes from a complex mix of species
Our ancestors’ genomes were built through successive waves of gene transfers. We tend to view ourselves and the complex cells […]
Protein in Homo erectus teeth suggests Denisovans gave us some of their DNA
Humanity’s ancestry has grown far clearer thanks to our ability to obtain ancient DNA. We now know that, as humans […]
Researchers try to cut the genetic code from 20 to 19 amino acids
Using AI tools, the team reworked part of the ribosome to need one less amino acid. The genetic code is […]
Meet the 19-meter Cretaceous kraken that swam with mosasaurs
On top of that, when analyzing the beaks, the team noticed a distinct pattern. The wear wasn’t uniform. The right […]
New fossil deposits show complex animal groups predating the Cambrian
The fossils, such as this oddity, consist of carbon-rich material in very old sediment deposits. Credit: Gaorong Li & Xiaodong […]
Tiny, long-armed dinosaur leads to rethink of dinosaur miniaturization
Small size seems to have come before a change in diet for a tiny dinosaur lineage. Alvarezsaurids were mostly small-bodied […]
A unicorn-like Spinosaurus found in the Sahara
But there was one thing that made S. mirabilis different from S. aegyptiacus. The word “mirabilis” in the newly discovered […]
Why are vertebrate eyes so different from those of other animals?
“We think that in this early deuterostome, the median eye contained both ciliary and rhabdomeric cells,” Kafetzis explains. As a […]
