— Self-assembling photovoltaic technology can keep repairing itself

   (Tuesday, 07 September 2010 07:52)

MIT scientists have created a novel set of self-assembling molecules that can turn sunlight into electricity; the molecules can be repeatedly broken down and then reassembled quickly, just by adding or removing an additional solution. In an attempt to imitate the  process of photosynthesis, Michael Strano, the Charles and Hilda Roddey Associate Professor of Chemical Engineering, [...]

The active ingredient of magic mushrooms, psilocybin, has been shown to reduce anxiety and improve mood in people with cancer. researchers from Harbor-UCLA Medical Center have found. Volunteers reported feeling less depressed and anxious two weeks after receiving psilocybin. Six months later, the level of depression was significantly lower in all volunteers than it had been before the [...]

  Stem cells have been touted as the potential key to treating ailments ranging from Parkinson’s disease and multiple sclerosis to spinal cord injuries, to name just a few. That’s because they can be made into any type of cell that’s needed - they’re essentially the plasticine of the cell world. The problem that scientists have encountered is the difficulty in growing them. For one thing, it’s hard to grow enough of them to perform large-scale experiments. For another, most of the materials upon which the stem cells...

     (Monday, 23 August 2010 22:08)

  

  Although wave power is attracting a lot of attention as a renewable energy source, it is possible to generate power from still water. All you need is an electrolyzer, which separates water into its two components, hydrogen and oxygen, then feeds them into a fuel cell. Electrolyzers, however, require catalysts to get the process rolling. While hydrogen production catalysts aren’t much of a problem, the platinum catalysts used for oxygen production are expensive, don’t last very long, and the creation of them incorporates...

  Deserts are the obvious locations for solar power plants. The land is cheap and the sunshine is plentiful. Unfortunately so too is the dust, dirt and wind that leads to dirty solar panels that can take a big hit in efficiency. Sending a guy around with a squeegee in the sweltering heat doesn’t sound like the best job in the world and self-cleaning systems that rely on water aren’t always an option in areas where clean water is hard to come by. Another solution is self-dusting solar panels...

  Recently, 29 students from Northwestern University in Illinois planned a terrorist attack. Researchers from the university were subsequently able to learn details of the attack, even though the students never admitted to anything. How was this possible? Well, essentially, the researchers read the students’ minds. More specifically, they monitored their P300 brain waves – brief electrical patterns in the cortex, which occur when meaningful information is presented to someone with “guilty knowledge.” In this case, it was a mock planned attack, but the research...

  More than 1,000 tons (2.2 million pounds) of titanium devices are implanted in patients worldwide every year with joint replacements one of the more common procedures. Light, strong and totally biocompatible, titanium is one of the few materials that naturally match the requirements for implantation in the human body. Researchers have now developed an improved coating technique that could strengthen the connection between titanium joint-replacement implants with a patient’s own bone. The stronger connection – created by manipulating signals the body’s own cells use to...

Actually, you’d probably use the nanofluidic “multi-tool” created by researchers at the National Institute of Standards and Technology (NIST) in the US. Before you start picturing a teeny-tiny Leatherman, which would admittedly be pretty cool, you should be aware that the NIST device is more like a coin separator, that sorts your nickels, dimes and quarters.

The same process would also see those plants generating their own power, thus meaning they would be both energy-neutral and emissions-free.

Nanoparticles tend to be more chemically reactive than ordinary-sized particles of the same material, making it hard to predict how they will act under different conditions and raising serious questions about the use of such particles – particularly inside the human body. Researchers have now developed a method for predicting the ways nanoparticles will interact with biological systems – including the human body – that could improve...
