    Getting creative to cut methane from cows

    View the video

    In a pasture outside Edmonton, Canada, you’ll find a few dozen cows doing what cows do: mostly eating. The average animal spends eight-plus hours a day filling its belly, or as is the case with cows, bellies. Along with that enormous appetite, cows are born with the ability to digest almost any plant they can chew, thanks to a multichambered stomach and a helpful army of...

    The wait for more Pluto data is almost over

    Get ready, we’re about to be inundated with postcards from Pluto. On September 5, the New Horizons spacecraft, now more than 62 million kilometers beyond Pluto, will begin a roughly year-long download of all the data it acquired during its brief visit with the dwarf planet in July. Only a few percent of that data was sent to Earth shortly after the encounter.

    It’s about time. Without new...

    The 3-D Printing Revolution

    Joshua Pearce takes unusual satisfaction in strolling through Walmart. The shelves laden with toys, household items, tools and clothing inspire in him a certain smugness, a pride in American entrepreneurship.

    Breaking it Down

    Suppose there was a fourth little pig. This one was a physicist. Unlike his brother the engineer, who built a house out of tried-and-true bricks, the physicist pig chose a building material by doing calculations based on fundamental principles. He settled on a substance made from silicon and oxygen, an abundant material with high bond strength and the aesthetic bonus of transparency. It was...

    Unknotting knot theory

    Sometimes, a simple, even childish question turns out to be connected to the deepest secrets of the universe. Here’s one: How many different ways can you tie your shoelaces?Mathematicians have been puzzling over that question for a century or two, and the main thing they’ve discovered is that the question is really, really hard. In the last decade, though, they’ve developed some powerful new...
