First transfusions of "manufactured" blood planned for 2016

First transfusions of "manufactured" blood planned for 2016 | Science |

According to the World Health Organization, approximately 107 million blood donations are collected globally every year.


Nonetheless, blood is often in short supply – particularly in developing nations.


Despite new safeguards, there's also still the risk of incompatibility, or of infections being transmitted from donors to recipients.


Charitable organization the Wellcome Trust hopes to address these problems, by developing the ability to manufacture blood outside of the body. Last week, it announced that test subjects should begin receiving transfusions of blood made with lab-grown red blood cells by late 2016.

Genetic Engineering Will Drive Food Security - Chilton (2014) - CSA

During the late 1970s and early 1980s, my research team worked out how a plant bacterium can be adapted as a tool to insert genes from another organism into plant cells. This helped open the door to new crop varieties with innovative traits... In 2013, I was one of three scientists honored as World Food Prize Laureates for our contributions to this technology... agricultural biotechnologists were chosen to win the 2013 prize, as it speaks to the importance of this new technology in addressing the food needs of future generations.


I have seen this technology develop from its early infancy to the fruition of the crops we see in the field today. It has been an amazingly rewarding journey to see what started out as a fundamental scientific and curiosity-driven study evolve into such wide application in the field. It is clear from the statistics, which show the many millions of acres of biotech-modified crops being harvested around the world, that the technology has taken off with remarkable speed...


The only sustainable approach to food security in 2050 and beyond is to unlock the potential of plants through innovation. Growers are rapidly adopting combined-trait crops for insect control, water optimization, yield improvement, oil and protein quality, and improved bioprocessing. Ultimately, these technologies help reduce chemical applications and provide simpler, more environmentally friendly farming practices (e.g., no till). Agricultural biotechnology will be a key driver of sustainable food production in the future...


In a real sense, the process that we use for genetically engineering a plant is a natural one. We learned how Agrobacterium manages to put genes into plant cells, and then we copied that process. We borrowed from a natural process... we can now do by choice what nature only does by chance.


With genetic engineering, we have a wide choice of genes... and we can precisely choose the genetic regions where we want to insert them, without any unintended consequences. In traditional cross-breeding, extra genes that you don’t want also find their way into the plant. It is impossible to avoid. As I see it, a genetically engineered plant is a much more defined and precise product...


What should be done by governing bodies, international organizations, funding agencies, and the scientific community to help feed the world in 2050? The single most important contribution that others can make is to provide accurate information about the food security challenge we are facing and the solutions that can meet the challenge. For too long, there has been misunderstanding and misinformation about modern agriculture technologies, especially GMOs. This has led to a state of public confusion and unnecessary concern over what this process is and how safe it is. I find this very unfortunate because it did not need to happen.


We have spent far too much time trying to correct false impressions rather than focusing on all the benefits that these technologies can provide. Let us focus on their potential for the future. The world will become a hungry place in one more generation. We will need this wonderful technology to improve the seeds of the future.

First-Ever Artificial Blood Transfusion

First-Ever Artificial Blood Transfusion | Science |

A French doctor has completed the first-ever artificial blood transfusion after extracting stem cells from a patient's bone marrow, which were then used to grow the red blood cells under laboratory settings. "After five days, 94 to 100 percent of the blood cells remained circulating in the body. After 26 days, 41 to 63 percent remained, which is a normal survival rate for naturally produced blood cells." The cells carried oxygen throughout the patient's body, just as normal red blood cells would.
