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.
Orange LED Light In Liquid Nitrogen The Science: When an LED is immersed in liquid nitrogen, the electrons lose a lot of thermal energy, even when the light isn’t turned on. In The World Of Science (10 Facts. How Things Work. Posted by admin on Dec 28, 2012 in Entertainment | 27 comments.

Did You Know Archive & The assassin bug wears the corpses of its victims like armor. With a name like the assassin bug, you can be sure this is one tough insect.

In the Philippines, to bring sustainable lighting to homes in impoverished communities, empty plastic bottles are being installed in ceilings. Filled with water and bleach, they refract sunlight, and provide light equivalent to a 55watt light bulb. - Almo. 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.

It was October 23, 2007 at 11:40am EST when I had my first ride to space on Discovery. She’s beautiful… just sad that this will be her last voyage. Looking forward to climbing aboard the flight deck when Discovery arrives at the Space Station in November. (9-23-2010). Incredible Photos from Space: Larry Tanner, NASA. Special thanks: Bethbeck’s blog On September 22, 2010, with the departure of the Expedition 23 crew, Colonel Douglas H. We thought that we should put some of the space photos together as a tribute to him and the whole ISS crew.
The following space photos are all visible on Astro_Wheels’ twitpic account, and we are eternally grateful to him for sharing these space photos with the world.

Albino Animals. Birdwatchers are rushing to Avebury, near Marlborough, Wiltshire to hopefully catch a glimpse of a rare albino jackdaw.
Author Andrew Collins was the first to photograph the bird which locals have named Jackie. Other fabulous albino animals include: According to Wikipedia there is no reported case of a true “albino” horse even though white horses have been referred to as albino in literature and some registries. All so-called “albino” horses have pigmented eyes, usually brown or blue, and thus are not true albinos. Many albino mammals, such as mice or rabbits, typically have a white hair coat, unpigmented skin and reddish eyes. Dominant white in horses is caused by the absence of pigment cells melanocytes, whereas albino animals have a normal distribution of melanocytes In other animals, patches of unpigmented skin, hair, or eyes due to the lack of pigment cells (melanocytes) are called piebaldism, not albinism nor partial albinism.
