One December night my family and my girlfriend both visited me in the small Missouri town where I went to college. As large flakes of snow fell, we walked to the school auditorium, where student jazz combos were giving a concert with a special guest. It’s thrilling to watch student performances, because there’s no guarantee it won’t be a complete disaster. In this case, it was far from that: the bands played perfect covers of “Dear Old Stockholm” and “Caravan.” The horn players launched into deeply felt, unpredictable solos—you could sense both the rigor of years of endless scales in the practice room and the need to prove they could do much more, the desire to surprise.

I had been a vegetarian for three years, and a pescatarian for all of 14 days, when the lobster incident happened.
On my part, the decision to grill two languid, mottled-blue and orange lobsters on a pleasant July day was motivated partially by a sense of adventure and partially by pure stubbornness. My boyfriend, Matt, had recently moved to Cape Cod: shellfish country, a place where most of his neighbors would never set off for a day at the beach without their clam rake.

Trees can flee from climate change—with a little help from a burly friend.
Humans, we hope, can retreat from the effects of global warming. But trees—though they have limbs—can’t uproot themselves to find a new home. If a tree species has adapted to a particular temperature range, it needs a way to stay in that range or risk extinction. Read the rest in NOVA Next.

When a building caught fire in colonial America, fire trucks equipped with high pressure water did not arrive to dampen the flames because they had yet to be invented.

If a black hole is the senior starting quarterback on your high school football team—dark, handsome, well-known, and admired by everyone—then a neutron star is the starting quarterback’s kid brother, a gangly freshman who marches to the beat of his own drummer and can’t help being overshadowed by the sheer magnitude of his older sibling.

When a child cannonballs into a pool, a simple series of waves radiate outward from the point where they plunged in. But if two children jump in at once, they create a more intricate waterscape. Where the two sets of waves meet, they interfere with each other. In some spots, the peak of one wave meets the valley of another, and they cancel each other out. The waves in that location disappear. Full Article »

The heart of every star is a forge for the building blocks of the universe. Since the day the universe began, stars have been taking the materials spit out by its formation and transforming them into the elements that make up everything we know: deserts, dinosaur bones, oak trees, apartment buildings, giant squids, jellybeans, and you.
