Raising concrete standards for oil and gas wells Raising concrete standards for oil and gas wells Whenever a company finds a target to mine oil or gas, environmentalists and residents on that land throw their arms in the air. There is no disputing the potential damage these projects could cause the environment. A big reason for this is that the wells can leak. These wells are lined with pipe that is sealed by concrete. Researchers are now working on an evolutionary race between testing methods and material improvements to make leaking wells a thing of the past.

Human ESC-derived hemogenic endothelial cells undergo distinct waves of endothelial to hematopoietic transition Human ESC-derived hemogenic endothelial cells undergo distinct waves of endothelial to hematopoietic transition Several studies have demonstrated that hematopoietic cells originate from endothelium in early development; however, the phenotypic progression of progenitor cells during human embryonic hemogenesis is not well described. Here, we define the developmental hierarchy among intermediate populations of hematopoietic progenitor cells (HPCs) derived from human embryonic stem cells (hESCs).
