Concerted nucleophilic aromatic substitutions
Nucleophilic aromatic substitution reactions have long been thought to occur primarily via stepwise mechanisms. New and sensitive methodology for measuring carbon kinetic isotope effects now shows that most such substitutions actually occur through concerted mechanisms.

MIT Researchers Develop a “Living Tattoo” Made from 3D Printed Bacteria
Researchers at the Massachusetts Institute of Technology are taking 3D printing one step further. Their findings, recently published in Advanced Materials, indicate that the methods used for traditional 3D printing can also be used to print living materials; they were able to integrate programmable....

The axolotl genome and the evolution of key tissue formation regulators
Sequencing and assembly of the 32-Gb genome of the Mexican axolotl reveals that it lacks the developmental gene Pax3, which is essential in other vertebrates; the genome sequence could improve our understanding of the evolution of the axolotl’s remarkable regenerative capabilities.

Evolution is acting on every creature including humans but sometimes it can happen quickly even in complex animals.
A New Bird Species Has Evolved on Galapagos And Scientists Watched It Happen
For the first time, scientists have been able to observe something amazing: the evolution of a completely new species, in the wild, in real-time. And it took just two generations.

Regeneration in distantly related species: common strategies and pathways
All animals capable of regenerating a lost body part, from an organ or a limb to the whole organism, use a common set of genes. This is the striking discovery of a team of researchers from the Center for Complexity and Biosystems of the University of Milan, led by Caterina La Porta. They analyzed...
