- Ubiquitin tags detected on non-protein biomolecules using new method
An innovative mass spectrometry method has detected ubiquitin on non-protein biomolecules, including glycogen in mouse liver. During fasting, glycogen in mouse liver shows increased ubiquitination, involving 1% of the liver’s total ubiquitin.
- Paleontology rocked by discovery of organic molecules in 66-million-year-old dinosaur bones
Scientists have found organic molecules in 66-million-year-old dinosaur bones, challenging the belief that fossilization destroys all organic material. The discovery was made in a well-preserved Edmontosaurus fossil from South Dakota using advanced techniques. This finding suggests that dinosaur fossils may still contain traces of their original proteins.
