A Clever New Chemistry Kit Your Kid Will Actually Want to Use

Posted: Published on April 10th, 2014

The prize-winning chemistry set. Photo: George Korir As a boy growing up in India, Manu Prakash once undertook a DIY pyrotechnics experiment that didnt quite go as planned. He managed to start a fire and burn his hand. I had an extreme chemistry experience, said Prakash, whos now a bioengineer at Stanford. Prakash hopes to kindle some of the same curiosity about chemistry (minus the actual combustion) with a new hand-crank operated chemistry set for kids. A prototype of the device just won the $50,000 first prize in a contest for inspiring science toyssponsored by the Gordon and Betty Moore Foundation and the Society for Science & the Public. (The runners up include a kid-friendly neurophysiology kit that converts electrical signals from the muscles and brain into lights and sound see the video below). A closeup of the device, with different colors representing different chemicals. Photo: Stanford University The chemistry kit developed by Prakash and graduate student George Korir manages to be both cutting edge and retro at the same time. It uses microfluidic channels like those found in modern DNA chips and other molecular biology equipment to move chemicals around and mix them together. But it also uses punch … Continue reading →

Music Box Inspires Portable $5 Chemistry Lab

Posted: Published on April 10th, 2014

The inspiration for a portable, powerful chemistry set came not from cloud computing or nanotechnology but a decidedly old-school source: a toy music box. The handheld device could be used where electricity and hospitals are scarce, allowing things like water testing and making medications. Stanford assistant professor of bioengineering Manu Prakash was struck by the idea when its wife brought home an old music box that used perforated paper to create a melody. By turning a crank, the paper is drawn through the device, and when a hole in the paper is encountered, a pin inside spins and plucks at a metal strip, creating a tone. But what if each pin, Prakash wondered, were to instead release a tiny droplet of a certain chemical? With the help of graduate student George Korir, Prakash managed to pair the music box mechanism with a more modern technology called a microfluidic chip. This uses tiny channels etched in silicon to deliver precise amounts of fluids stored elsewhere on the chip but generally require powered electronics to use, driving up the cost and difficulty of deploying them. When combined with the music box, however, the channels can be activated with the pins which once … Continue reading →

Cell therapy – Wikipedia, the free encyclopedia

Posted: Published on April 10th, 2014

Cell therapy (or Cellular therapy) is therapy in which cellular material is injected into a patient.[1] Cell therapy originated in the nineteenth century when scientists experimented by injecting animal material in an attempt to prevent and treat illness.[2] Although such attempts produced no positive benefit, further research found in the mid twentieth century that human cells could be used to help prevent the human body rejecting transplanted organs, leading in time to successful bone marrow transplantation.[3] Today two distinct categories of cell therapy are recognized.[1] The first category is cell therapy in mainstream medicine. This is the subject of intense research and the basis of potential therapeutic benefit.[4] Such research, especially when it involves human embryonic material, is controversial. The second category is in alternative medicine, and perpetuates the practice of injecting animal materials in an attempt to cure disease. This practice, according to the American Cancer Society, is not backed by any medical evidence of effectiveness, and can have deadly consequences.[1] Cell therapy can be defined as therapy in which cellular material is injected into a patient.[1] There are two branches of cell therapy: one is legitimate and established, whereby human cells are transplanted from a donor to a … Continue reading →

This article is about the medical therapy. For the cell type, see Stem cell. Stem cell therapy is an intervention strategy that introduces new adult stem cells into damaged tissue in order to treat disease or injury. Many medical researchers believe that stem cell treatments have the potential to change the face of human disease and alleviate suffering.[1] The ability of stem cells to self-renew and give rise to subsequent generations with variable degrees of differentiation capacities,[2] offers significant potential for generation of tissues that can potentially replace diseased and damaged areas in the body, with minimal risk of rejection and side effects. A number of stem cell therapies exist, but most are at experimental stages, costly or controversial,[3] with the notable exception of bone-marrow transplantation.[4] Medical researchers anticipate that adult and embryonic stem cells will soon be able to treat cancer, Type 1 diabetes mellitus, Parkinson's disease, Huntington's disease, Celiac disease, cardiac failure, muscle damage and neurological disorders, and many others.[5] Nevertheless, before stem cell therapeutics can be applied in the clinical setting, more research is necessary to understand stem cell behavior upon transplantation as well as the mechanisms of stem cell interaction with the diseased/injured microenvironment.[5] For over … Continue reading →
