Scientists looked at acorn worm for clues as to why vertebrates cannot regenerate their bodies

A group of researchers found that the Ptychodera flava draws on reprogramming-based mechanisms. It is a worm-like marine organism capable of regenerating its entire head or body. It helps somatic cells in higher-order animals branch out into complete body parts. It is known as...

Scientists explore the genetic basis of the root economics spectrum

Ecologists have put forward the root economics spectrum hypothesis by analyzing the acquisition-conservation trade off in root systems among different plants. Finer and cost-effective absorptive roots are seen in some plant species. These contribute to rapid nutrient uptake but have shorter lifespans. Other roots...
