Dr Molly Stevens and her team in the Department of Materials and the Institute of Biomedical Engineering moved one step closer to understanding how to grow replacement bones with stem cell technology in July 2009. Dr Stevens, whose study was published in the journal Nature Materials, compared the ‘bone-like’ material grown from three different, commonly used, clinically relevant cell types and discovered that the materials that were grown from mouse skull and bone marrow stem cells successfully mimicked many of the hallmarks of real bone. She says: “It brings us one step closer to developing materials that will have the highest chance of success when implanted into patients.” Which of the following headings is suitable to the passage?

Scientists had largely overlooked the Hesperian Epoch as it was thought that Mars was then a frozen wasteland. Excitingly, our study now shows that this middle period in Mars’ history was much more dynamic than we previously imagined.”Which of the following alternatives is WRONG, according to the passage?
