  • This kind of disease modeling could have a great impact in the near term, says MIT professor Sangeeta Bhatia, who is developing liver tissue to study hepatitis C and malaria infection.
  • liver is difficult to grow outside the human body because cells tend to lose their function when they lose contact with neighboring cells. “
  • In a large-scale project recently funded by the Defense Advanced Research Projects Administration, several MIT faculty members are working on a “human-on-a-chip” system that scientists could use to study up to 10 human tissue types at a time.

  • developing regenerative therapies that help promote wound healing.
  • Endothelial cells, normally found lining blood vessels, could help repair damage caused by angioplasty or other surgical interventions; smoke inhalation; and cancer or cardiovascular disease.
  • One of the earliest successes of implantable tissues was the development of artificial skin, which is now commonly used to treat burn victims.
  • Langer is now working on more complex tissues, such as cardiac-tissue scaffolds that include electronic sensors and a synthetic polymer that could restore vocal-cord function in people who have lost their voices through overuse or other types of damage
  • In Bhatia’s lab, where tissue-engineering research is evenly divided between modeling diseases and working toward implantable organs, researchers recently developed 3-D liver tissues that include their own network of blood vessels

    ScienceDaily (Nov. 3, 2011) - Scientists have recently succeeded in rejuvenating cells from elderly donors (aged over 100). These old cells were reprogrammed in vitro to induced pluripotent stem cells (iPSC) and to rejuvenated and human embryonic stem cells (hESC): cells of all types can again be differentiated after this genuine "rejuvenation" therapy. The results represent significant progress for research into iPSC cells and a further step forwards for regenerative medicine.

    Researchers from Rice University and Baylor College of Medicine (BCM) have broken one of the major roadblocks on the path to growing transplantable tissue in the lab: They've found a way to grow the blood vessels and capillaries needed to keep tissues alive.

  • Resources are fixed and finite, surely? Wrong!
  • key developments in technology created new resources.
  • resources like computing power, medicines and knowledge are becoming more and more abundant.

  • The reason why the total forested area in Europe and North America is increasing year by year is because we no longer need to burn the trees.
  • We can create resources as well as consume them.

    The author makes some important observations that are astoundingly political and may be uncover the core to today's religious interests in science and technology. Major points of interest, when referring to the human eras of social/scientific/technological development: "At each stage, a new resource became available. Something that was previously unknown, unavailable or unusable suddenly became a valuable commodity. In other words, key developments in technology created new resources. The quantity of available resources has continued to expand throughout human history."

    Free Download - StanfordUniversity - January 22, 2009 - Karl Deisseroth is pioneering bold new treatments for depression and other psychiatric diseases. By sending pulses of light into the brain, Deisseroth can control neural activity with remarkable precision. In this short talk, Deisseroth gives an thoughtful and awe-inspiring overview of his Stanford University lab's groundbreaking research in "optogenetics".
