Last week an editorial in the journal Science raised important questions about the safety of synthetic biology. In particular, it asked whether we can ensure safe practices in the more shady research arenas, such as the DIY synthetic biology movements. In 2014, the European Commission defined synthetic biology as, "the application of science, technology and engineering to facilitate and accelerate the design, manufacture and modification of genetic materials in living organisms". It was followed last month by a draft opinion from the commission's scientific committees that focuses on risks in synthetic biology. Specifically, it asked whether the methods used to assess the potential risks of the field were sufficient. To discuss the implications, Ian Sample is joined by Nicola Davis, commissioning editor of Observer Tech Monthly, and Professor Paul Freemont from Imperial College, London, who is co-director of its Centre for Synthetic Biology and Innovation. Dr Filippa Lentzos from King's College London also joins us down the line from Switzerland. The consultation on synthetic biology can be found here. Also on the show we feature our picks from the week's science news, including: the discovery of a new class of antibiotic; how scientists are trying to extend our lives; and, … Continue reading →

IMAGE:This is the cover for Stem Cells, Tissue Engineering and Regenerative Medicine. view more Credit: World Scientific, 2015 In his latest book published by World Scientific, Professor David Warburton from The Saban Research Institute of Children's Hospital Los Angeles and the University of Southern California presents a collection of essays on the current state of the regenerative medicine and stem cell research field. Entitled Stem Cells, Tissue Engineering and Regenerative Medicine, this up-to-date compendium surveys current issues in stem cell biology and regenerative medicine. Topics range from key concepts in regenerative medicine to the newest progenitor cell therapies for organ systems, to advice on how to set up a pluripotent stem cell laboratory. Overviews of the most recent progress in stem cell research describe work that is in the pre-clinical pipeline from scientists working at The Saban Research Institute of Children's Hospital Los Angeles and colleagues around the world. "The book addresses some of the big questions faced by researchers in the field of stem cell biology and regenerative medicine," said Professor Warburton. "Those of us working in this field in California are positively impacted by the critical funding provided by the citizens of the state through the California Institute … Continue reading →

Contact Information Available for logged-in reporters only Newswise For swimming through sand, a slick and slender snake can perform better than a short and stubby lizard. Thats one conclusion from a study of the movement patterns of the shovel-nosed snake, a native of the Mojave Desert of the southwest United States. The research shows how the snake uses its slender shape to move smoothly through the sand, and how its slippery skin reduces friction both providing locomotive advantages over another sand-swimmer: the sandfish lizard native to the Sahara Desert of northern Africa. The study provides information that could help explain how evolutionary pressures have affected body shape among sand-dwelling animals. And the work could also be useful in designing search and rescue robots able to move through sand and other granular materials. Using X-ray technology to watch each creature as it moved through a bed of sand, researchers studied the waves propagating down the bodies of both the snakes and sandfish lizards. Granular resistive force theory, which considers the thrust provided by the body waves and the drag on the animals bodies, helped model the locomotion and compare the energy efficiency of the limbless snake against that of the four-legged … Continue reading →
