    LEDsThe strange quantum state of entanglement isn't just challenging to think about, it's hard to create. This "spooky" phenomenon-in which two particles are linked, even if they're separated by distance-can be created by scientists in the lab using bulky lasers. But scientists published a study in Nature today in which they created a light-emitting diode (LED) that produces entangled photons.

    Low-Cost Multi-point Interactive Whiteboards Using the Wiimote Since the Wiimote can track sources of infrared (IR) light, you can track pens that have an IR led in the tip. By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays. Since the Wiimote can track upto 4 points, up to 4 pens can be used. It also works great with rear-projected displays.

    ScienceDaily (May 9, 2011) - Mayo Clinic researchers have designed a new tool for identifying protein function from genetic code. A team led by Stephen Ekker, Ph.D., succeeded in switching individual genes off and on in zebrafish, then observing embryonic and juvenile development. The study appears in the journal Nature Methods.

    A 36-year-old man has received the world's first synthetic trachea, made from a synthetic scaffold seeded with his own stem cells, in an operation at the Karolinska University Hospital in Stockholm, Sweden. Professor Paolo Macchiarini of Karolinska University Hospital and Karolinska Institutet led an international team, including professor Alexander Seifalian from University College London, who designed and built the nanocomposite tracheal scaffold, and Harvard Bioscience, which produced a specifically designed bioreactor used to seed the scaffold with the patient´s own stem cells. The cells were grown on the scaffold inside the bioreactor for two days before transplantation to the patient. Because the cells used to regenerate the trachea were the patient's own, there has been no rejection of the transplant and the patient is not taking immunosuppressive drugs. "The big conceptual breakthrough is that we can move from transplanting organs to manufacturing them for patients," says David Green, the president of Harvard Bioscience in Holliston, Massachusetts. Transplantations of tissue-engineered windpipes with synthetic scaffolds in combination with the patient's own stem cells as a standard procedure means that patients will not have to wait for a suitable donor organ. Patients could benefit from earlier surgery and have a greater chance of cure. This would be of especially great value for children, since the availability of donor tracheas is much lower than for adult patients.

  • Several trends came together to increase the professional nature of scientific work. First was the increasing cost of scientific work and its complexity. Scientific equipment became more precise and expensive. Telescopes, like those by Herschel, became bigger and bigger. Also, the amount of knowledge one needed to gain to contribute became increasingly daunting.
  • Second, the universities changed. Pioneered by the German states, which at the beginning of the 19th century was dismissed as a scientific backwater, universities began offering focused majors which trained students in a specific discipline rather than classical education as a whole. This was pioneered by Wilhelm von Humboldt, brother of the famous scientist Alexander von Humboldt, who was the Prussian Minister of Education.
  • Germany, once united, also provided impetus to two other trends that accelerated their dominance of science and the decline of amateurs. First, was the beginning of large-scale state sponsorship of science through grants which were first facilitated through the Kaiser Wilhelm Institute (now the Max Planck Institute). This eventually supplanted prizes as the dominant large-scale source of scientific funding. Countries like France that relied on prizes began to fall behind. Second, was the intimate cooperation between industrial firms like BASF and universities.

  • he final nail in the coffin was undoubtedly the Second World War. The massive mobilization of scientific resources needed to win and the discovery of war-winning inventions such as the atomic bomb and self-correcting bomb sight (with help from Norbert Wiener of MIT) convinced the nations of the world that the future was in large-scale funding and support of science as a continuous effort. Vannevar Bush, former president of MIT, and others pioneered the National Science Foundation and the military also invested heavily in its own research centers. Industrial labs such as those from Bell Labs, GE, Kodak, and others began dominating research as well. Interestingly, the first military investment in semiconductors coupled with research from Bell Labs led to what is now known as Silicon Valley.

    Professor Andre Geim, who along with his colleague Professor Kostya Novoselov won the 2010 Nobel Prize for graphene - the world's thinnest material, has now modified it to make fluorographene - a one-molecule-thick material chemically similar to Teflon. Fluorographene is fully-fluorinated graphene and is basically a two-dimensional version of Teflon, showing similar properties including chemical inertness and thermal stability.
