  • Destination Science: 17 Best Places for a Geek to Go This Summer | DISCOVER Magazine

    Updated: 2012-03-30 19:45:00
    A man was working on a plot of private land in Arkansas last fall when he uncovered a set of huge, fossilized dinosaur tracks. Also last year, interested amateurs photographed tides on low-lying stretches of the California coast to help predict the effects of climate change; they also checked up on local patches of milkweed, prime real estate for monarch butterflies, to keep tabs on the insects’ migration patterns. Scientific wonders are accessible to anyone with the curiosity to seek them out, and summer is the perfect time to get exploring. In that spirit, we’ve brainstormed a whole season’s worth of places to go, sights to see, and things to do. There are destinations across the country, so whether you’re in Albany or Albuquerque, you should be able to find something nearby. The adventurous among you may find yourselves strapping on an undersea helmet and strolling through a submarine kelp forest or wielding a Geiger counter in a field strewn with remnants of the atomic era, while those traveling with the family can swing by the bayou for a relaxed but rewarding swamp-by-boat tour. And plan to watch the sunset on June 5—there won’t be another like it for 105 years... Skip to the quick reference guide of summer getaways r see the descriptions below.  GET DOWN TO EARTH

National Park, WyomingThe plume of molten rock that rises from more than 400 miles inside Earth beneath Yellowstone National Park powers the 10,000 springs, geysers, and other thermal features located where magma-heated water and steam come simmering to the surface. Yellowstone’s biggest hot spring, Grand Prismatic, also hosts some of the planet’s strangest, hardiest life. “Yellowstone’s known for its bison and bald eagles,” says John Spear, an environmental microbiologist at the Colorado School of Mines, in Golden, “but it’s really a microbial wonderland”...

  • The Continent Where Climate Went Haywire | DISCOVER Magazine

    Updated: 2012-03-26 19:00:00
    “The river came up to right where we’re sitting, and the waters were more than two feet deep,” Peter Goodwin tells me in the driveway of his ranch-style house perched on the banks of the Balonne River in St. George, a village of 3,500 in eastern Australia. It is a drizzly Sunday afternoon in April, three months after a devastating flood that drenched a landmass the size of France and Germany combined and isolated the town after the rain-swollen river rose to a record 45 feet. Agricultural areas like St. George were hardest hit by the relentless rains and overflowing rivers that swamped roads, cut off power lines, washed away vineyards and fruit orchards, drowned thousands of head of cattle and other livestock, and covered homes and everything inside them in thick layers of sediment and mud. Shell-shocked residents are still digging out from under the debris. “That’s the hard part of the flood—the aftermath,” says Goodwin, 60, a crusty, compactly built man with piercing blue eyes and calloused hands who works as an operations manager for the local municipality and has been staying with his grown daughter while he makes his home habitable again. “You get a lot of help during the flood, but then everyone settles back into their routine. There are a lot of houses down there that are still empty,” he adds, gesturing toward the riverbank. “And they will be for a long time to come”...

  • You Can Teach an Old Drug New Tricks | DISCOVER Magazine

    Updated: 2012-03-21 16:35:00
    Old drugs often get a surprising second life. In just the past few weeks, the news has buzzed about a skin cancer drug that may cure Alzheimer's, an osteoporosis medication that can kill malaria parasites, a leukemia drug that inhibits the Ebola virus, and many more. These drugs and their newly discovered possible uses are just a reflection of how modern drug discovery works. Sometimes it is pure serendipity: a curious and surprising side effect pops up in clinical trials. Other times, we've stacked the odds by testing drugs already approved for one use to see if they can treat other conditions. Since these known drugs have already been proven relatively safe, their clinical trials involve less hassle and expense... Image: iStockphoto

  • Back to The Final Frontier | DISCOVER Magazine

    Updated: 2012-03-19 17:05:00
    Spring 2001, amid the manicured lawns of the Princeton University campus, I was recumbent in an office chair with my mind in the universe when the phone rang. It was the White House. They wanted me to join a commission to study the health of the aerospace industry. I agreed, but at first I was indifferent. I don’t know how to fly an airplane. But then I read up on that sector and realized they had lost half a million jobs in recent years. Something bad was going on. The commission’s first meeting was to be at the end of September. And then came 9/11. I live—then and now—four blocks from Ground Zero. My windows are right there. I was supposed to go to Princeton that morning, but I had some overdue writing to finish, so I stayed home. One plane goes in; another plane goes in. At that point, how indifferent could I be? I had just lost my neighborhood to two airplanes. Duty called. I was a changed person. Not only had the nation been attacked, so had my backyard. I distinctly remember walking into the first meeting. The 11 other commissioners filled the room with testosterone. There was General this and Secretary of the Navy that and Member of Congress this. It’s not as though I have no testosterone, but it’s Bronx testosterone. The kind where, if you get into a fight on the street, you kick the guy’s butt. This I-build-missile-systems testosterone is a whole other kind. Even the women on the commission had it: A former congresswoman from the South, who had an Air Force base in her district, deployed a vocal tone perfectly tuned to say, “Kiss my ass.” Another one was chief aerospace analyst for Morgan Stanley; having grown up as a Navy brat, she had the industry by the gonads. On that commission, we traveled the world to see what cultural or economic forces might be influencing the aerospace industry’s stability here in America. We visited China before they put a man in space. I carried with me the common stereotype of everybody’s riding bicycles along broad boulevards, but instead, Audis and Mercedes Benzes and Volkswagens filled the streets. Cars dominated the roads, not bicycles. Then I went home and looked at the labels on all my stuff; half of it had been made in China. Lots of our money was already going there. On a side tour we visited the Great Wall. A tourist attraction, of course, but in its day, a military project. I looked far and wide but saw no evidence of technology, just the bricks that comprised the wall. As an experiment, I pulled out my cell phone and seamlessly managed to call my mother in New York. “Oh, Neil, you’re home so soon!” was her first remark. No, I was 8,000 miles away, yet that cell phone connection was the best I’ve ever had—ever. Nobody in China is uttering America’s cell phone mantra, “Can you hear me now?” So when China announced, “We’re going to put somebody in orbit,” sure enough, I knew it was going to happen...

  • The Lethal Gene That Emerged in Ancient Palestine and Spread Around the Globe | DISCOVER Magazine

    Updated: 2012-03-05 14:20:00
    iStockphoto Shonnie Medina was a happy 
girl who felt she would die young. Her physical beauty, when she was a young woman in Culebra and a young wife in Alamosa, was the primary thing that people mentioned about her. Photographs and snatches of videotape don’t quite capture it because fundamentally what people were talking about was charisma. It came through her looks when she was in front of you, tossing her full head of dark hair and giving you her full attention. Then her beauty acted like a mooring for her other outward qualities, undulating from that holdfast like fronds of kelp on the sea. Then Shonnie was magnetic, vain, kind to others, religious without reservation, funny, a little goofy, and headstrong. The gene Shonnie inherited, known as BRCA1.185delAG, also has a long pedigree. Its discovery in the Hispano community confirmed events of half a millennium before in Spain that are echoing still. Most likely the mutation arrived by way of Sephardic Jews who converted to Catholicism under pressure from the Spanish Inquisition. From Spain they traveled to the New World, where eventually they seeded the modern Hispano population. Indian blood and new terrain erased part of the history those emigrants carried, assuming they were even aware of their Jewish legacy. For the Hispano Catholic people of northern New Mexico and southern Colorado, Jewish ancestry was a will-o’-the-wisp of memory and culture, which many people had heard about without knowing if it was true. Shonnie’s mutation shows that it is. The breast-cancer mutation 185delAG entered the gene pool of Jews some 2,500 years ago, around the time they were exiled to Babylon. Random and unbidden, the mutation appeared on the chromosome of a single person, who is known as the founder. In the same sense that Abraham is said to have founded the Jewish people, scientists call the person at the top of a genetic pyramid a founder...
