Cambridge, Mass. - November 26, 2012 - Now you see it, now you don't. A new device invented at the Harvard School of Engineering and Applied Sciences (SEAS) can absorb 99.75% of infrared light that shines on it. When activated, it appears black to infrared cameras. Composed of just a 180-nanometer-thick layer of vanadium dioxide (VO2) on top of a sheet of sapphire, the device reacts to temperature changes by reflecting dramatically more or less infrared light.

Efficient Genetic Editing
As potential next-generation therapeutics and research tools, few life sciences technologies hold more promise than genome-editing proteins – molecules that can be programmed to alter specific genes in order to treat or even cure genetic diseases. There's at least one catch though – getting genome-editing proteins into cells, where they need to be to access the genome, is a major challenge, especially in live animals or human patients.
Scientists Engineer Toxin-secreting Stem Cells to Treat Brain Tumors
Harvard Stem Cell Institute scientists at Massachusetts General Hospital have devised a new way to use stem cells in the fight against brain cancer. A team led by neuroscientist Khalid Shah, MS, PhD, who recently demonstrated the value of stem cells loaded with cancer-killing herpes viruses, now has a way to genetically engineer stem cells so that they can produce and secrete tumor-killing toxins.
Harvard Study Offers First-ever Look at How NCAA Concussion Guidelines Are Followed
Though most NCAA colleges and universities have created programs to help athletes deal with concussions, a new Harvard study has found that, when it comes to specific components of those plans, many institutions still lag behind accepted standards.
From Human Embryonic Stem Cells to Billions of Human Insulin Producing Cells
Harvard stem cell researchers today announced that they have made a giant leap forward in the quest to find a truly effective treatment for type 1 diabetes, a condition that affects an estimated three million Americans at a cost of about $15 billion annually: With human embryonic stem cells as a starting point, the scientists are for the first time able to produce, in the kind of massive quantities needed for cell transplantation and pharmaceutical purposes, human insulin-producing beta cells equivalent in most
Scientists Develop Barcoding Tool for Stem Cells
A 7-year-project to develop a barcoding and tracking system for tissue stem cells has revealed previously unrecognized features of normal blood production: New data from Harvard Stem Cell Institute scientists at Boston Children's Hospital suggests, surprisingly, that the billions of blood cells that we produce each day are made not by blood stem cells, but rather their less pluripotent descendants, called progenitor cells. The researchers hypothesize that blood comes from stable populations of different long-lived progenitor cells that are responsible for giving rise
