Scientists are discovering more ingredients for life on Ceres.For the first time, researchers have detected organic compounds on the dwarf planet, the second-biggest object in the asteroid belt between Mars and Jupiter. The materials contain hints of carbon and ammonia, the chemical components that exist in all known life on Earth. The scientists don’t know exactly what these compounds are, but they say they resemble some tar-like substances that can be found here.The findings, described in a study published Thursday in the journal Science, come from data collected by the Dawn spacecraft, which NASA launched in 2007 to study Ceres and its neighbor inside the asteroid belt, Vesta. Previous observations by Dawn, as well as space telescopes, have shown evidence of water ice, ammonia, salt, and … Read the rest

In this weekly series, Associate Editor Tim Chin and Test Cook Sasha Marx take you behind the scenes of Cook’s Science and give you a glimpse into our recipe development process, from how we come up with recipe ideas, to test kitchen failures, to discoveries we make along the way. This week, Tim shares his feelings on birthday cake and talks about his latest recipe challenge. In keeping with the spirit of procrastination that so clearly defines my generation, this week I thought I’d write about my next assignment: developing a birthday cake recipe that goes from mixing bowl to candles-lit in 30 minutes. First of all, the notion that cake must be presented/consumed on one’s day of birth kind of infuriates me. Do you really … Read the rest
Next time you want to tell a loved one how you feel, you can build them an electrically powered heart. In the video above posted on YouTube by MrfixitRick, two copper-wire hearts spin together as one in a romantic dance (set to the doo-wop tune “Be Excellent to Each Other”). The simple spinning invention is called a homopolar motor. These motors are easy to make. To build one of your own, all you need are three common household items: copper wire, an AA battery, and a magnet. For the magnet in the video, MrfixitRick used a bass speaker and a stack of pennies to direct the current flow. The flat, negative end of the battery is placed on top of the magnet. When the copper wire … Read the rest
