[:es]An organic compound called formamide could have acted in place of water as a solvent (meaning it can dissolve molecules) in early life on Earth, according to new research describing how formamide could have formed when exposed to natural concentrations of radioactive elements[:]

[:es]One of biology’s great mysteries is how a single fertilized egg gives rise to the multitude of cell types, tissues, and organs that fit together to make a body. Now, a combination of single-cell sequencing technologies and computational tools is providing the most detailed picture yet of this process. In three papers online in Science…
