| Growth-promoting, anti-aging retinal at the root of plant growth too Posted: 26 Aug 2021 02:01 PM PDT What do frog eggs have in common with 'anti-aging' creams? Their success depends on a group of chemical compounds called retinoids, which are capable of generating and re-generating tissues. A new study in plants shows that retinoids' tissue-generating capacities are also responsible for the appropriate development of roots. |

Taytalura is the first three-dimensionally preserved early lepidosaur fossil that allowed scientists to infer with great confidence it's placement in the evolutionary tree of reptiles and aids in closing the gap of our knowledge of the origin and early evolution of lepidosaurs. |
