This is a photo of the Chernobyl "Elephant's Foot", a solid mass made of a little melted nuclear fuel mixed with lots and lots of concrete, sand, and core sealing material that the fuel had melted through. The photo was taken in 1996. At that point, the Elephant's Foot had cooled enough that a human being could stand directly in front of it for an hour before receiving a lethal dose of radiation. When the Foot was first discovered, shortly after the 1986 accident at the Chernobyl power plant, it delivered a lethal dose in just five minutes. You can read Kyle Hill's interesting history of the Elephant's Foot at Nautilus. And be sure to check out this 1991 video that shows how people were able to rig up robotic camera systems to safely take photos of the thing (though, as Hill points out, not all the photos of Elephant's Foot were taken safely).
A favorite kitchen chemistry (and physics) experiment of kids (and adults), Ooblek is the weird result of mixing cornstarch with water. Now, MIT engineers have developed a mathematical model that can predict and simulate how the non-Newtonian fluid switches between liquid and solid depending on the pressure applied to it. From MIT News: Aside from […]

Stanley Whittingham and Dr. John Goodenough (Charles Dharapak / Yoshiaki Sakamoto / Kyodo News / Binghamton University) The 2019 Nobel Prize in Chemistry has been awarded to three scientists whose work developing lithium-ion batteries made mobile phones, iPads, laptops, and electric cars possible. The three recipients are U.S. engineer […]

There’s overwhelming support for clean energy, and the planet is giving us more reasons to invest in renewable power sources with every passing year. Even in the most inhospitable areas, wind and solar can provide a good chunk of our power, if not all of it. So why aren’t we all taking advantage of it? […]
Hey, we love Netflix and Hulu, but let’s face it: The whole setup doesn’t exactly encourage active viewing. For all the binge-watching we’ve done, it’s tough to expand our horizons or learn anything new – except for how many episodes of “The Office” it takes to make us fall asleep. It was only a matter […]
