Scientists want to laser-heat stuff to ten million degrees
Researchers at Imperial College London believe that they've created a method that could prove critical in the search for unlimited clean energy. The team has produced a theoretical method that, at least on paper, is capable of super-heating an object to ten million degrees in a fraction of a second. It's hoped that technology like this, if proven in the real world, will form a key component of a fusion reactor that'll provide a warm light for all mankind.
Alt-week 20.10.12: our oldest primate ancestor, the birth of the moon and a planet with four stars
Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days. Most mornings, we wake up with little to no idea what happened the day before, let alone last week. Fortunately, they don't let us run important scientific research projects. Or maybe they do, and we just forgot? This week (and most others as it goes) we definitely leave it to the pros, as we get some insightful glimpses at some important origins. Ball Lightning, the moon and even us humans are the benefactors of those tireless scientists, who work hard to explain where it all comes from. There's also a planet with four stars that sees the first few paragraphs of its origin story excitedly written out. One thing we never forget, however, is that this is alt-week.
Periodic table blasted onto a single human hair using ions, human reportedly wants his hair back
We've seen the Torah inscribed on a surface the size of a pin, and the atomic pen making inroads into even more impressive feats, but tiny writing never ceases to amaze us. Now, it seems, the entire periodic table of the elements has been scribed onto a single hair -- that of Martyn Poliakoff, Professor of Chemistry at the University of Nottingham. The project involved magnifying the hair under an electron microscope, and 'writing' on it with ions using an ion beam writer to imprint the entire table of elements onto the hair. As you'll see in the video after the break, the results are quite impressive albeit very small.
Ionic cooling system adapted for laptop use, scalded legs cautiously rejoice
To be totally candid, we can't even utter the word "ionic" without thinking of Sharper Image, but the concept here actually seems like one that just might benefit the public at large... or at least those of us forced to cook our upper legs on a daily basis. San Jose-based Tessera, in cooperation with the University of Washington, has adapted an ionic cooling system for use in everyday laptops. The magic elixir consists of two electrodes, one of which is used to ionize air molecules such as nitrogen, while the other acts as a receiver for those molecules. According to reports, this method can extract around 30 percent more heat from a lap burner than the traditional "fan and more fans" approach. Still, a major obstacle remains in terms of ensuring that the electrodes remain reliable throughout the life of a laptop, but if Tessera has its druthers, some form of the system will be commercialized next year.
