15 Awesome Chemistry GIFs You don’t need to watch Breaking Bad to know that chemistry is pretty awesome. Below, we explore our favorite 15 chemistry GIFs and the science behind them (when we could figure it out): Melting Metal With Magnets The Science: The copper wire has a significant amount of AC electricity running through it, causing it to act like a really strong electromagnet. In the metal slug, eddy currents form due to the magnetic field the copper wire is causing while the copper wire has high frequency AC flowing through it. The metal slug’s electric resistance causes a portion of the electric energy to turn into heat, but the heat builds up until the metal slug becomes white hot and melts.

Homicide Victims Rarely Talk to Police," and Other Horrible Headlines From a friend, who got them from a friend, who got them from someone else, here’s a collection of newspaper headlines that don’t quite accomplish what the writer set out to accomplish. Anyone who has ever written or published anything can surely sympathize — and laugh. (P.S.: Are any of them real?) Lifes Blueprints: Levis Takes a Cue From Bees To Make Stronger Jeans The discipline of biomimicry—defined by Biomimicry Institute founder Janine Benyus as "a way of seeking sustainable solutions by borrowing life's blueprints, chemical recipes, and ecosystem strategies"—has produced wind turbines shaped like whales' tails, solar panels modeled after butterfly wings, and cities and companies organized after mushrooms. Now Levi's is seeking inspiration in the way bees build their hives to improve the durability and strength of its clothes. The company recently took a multidisciplinary team of designers, technical and sustainability experts from across various departments and sent them out into the Montana wilderness with Benyus to look for ideas. "One thing we looked at was where in nature the reaggregation of fiber is performed," explains Paul Dillinger, senior director of global design for Levi's. "Bees. They collect resins from plants and create cross-linking natural resin to make short fibers.

Why Nikola Tesla was the greatest geek who ever lived Additional notes from the author: If you want to learn more about Tesla, I highly recommend reading Tesla: Man Out of Time Also, this Badass of the week by Ben Thompson is what originally inspired me to write a comic about Tesla. Ben's also got a book out which is packed full of awesome. There's an old movie from the 80s on Netflix Instant Queue right now about Tesla: The Secret of Nikola Tesla. It's corny and full of bad acting, but it paints a fairly accurate depiction of his life.

How Animals See the World The human eye is pretty amazing, but there are some things it cannot do such as see ultraviolet light or detect images at a great distance. The visual capabilities on non-human creatures can help to open our eyes to the possibilities beyond our limited sight. This infographic, published by Mezzmer, looks at vision from some animal’s point of view.

With a name like the assassin bug, you can be sure this is one tough insect. As it turns out though, the assassin bug doesn’t just kill and eat its victims—it also wears their exoskeletons as part of its suit of armor. In a way, this Malaysian bug is probably the closest thing the insect world has to a deranged serial killer.

Rising CO<sub>2</sub> levels linked to global warming during last deglaciation Many scientists have long suspected that rising levels of carbon dioxide and the global warming that ended the last Ice Age were somehow linked, but establishing a clear cause-and-effect relationship between CO2 and global warming from the geologic record has remained difficult. A new study, funded by the National Science Foundation and published in the journal Nature, identifies this relationship and provides compelling evidence that rising CO2 caused much of the global warming. Lead author Jeremy Shakun, who conducted much of the research as a doctoral student at Oregon State University, said the key to understanding the role of CO2 is to reconstruct globally averaged temperature changes during the end of the last Ice Age, which contrasts with previous efforts that only compared local temperatures in Antarctica to carbon dioxide levels. Here is what the researchers think happened. Shakun said there is "an enormous amount" of carbon sequestered in the deep ocean.
