Three miles (five kilometers) below the surface of the Caribbean Sea (map), great volcanic chimneys gush subterranean water hot enough to melt lead. Found via robotic submersibles on April 6, these two-story-tall "black smokers" are the world's deepest known hydrothermal vents, scientists announced from aboard a research ship Sunday. "It was like wandering across the surface of another world," geo
Lightning makes mushrooms more plentiful, according to ongoing research that offers a solid scientific basis for Japanese farming lore. For generations, Japanese farmers have welcomed storms over their fields based on the belief that lightning strikes provoke plentiful harvests of mushrooms, which are staples of Japanese cuisine. (Related: "New Lightning Type Found Over Volcano?") Currently, mushr
Mystery Disk at Epsilon AurigaeEpsilon Aurigae, a star 2,000 light-years away, is eclipsed by a dark, dusty disk in an artist's conception. Since the 1820s astronomers have seen Epsilon Aurigae get eclipsed by a mysterious companion for 18 months every 27 years. In fact, the yellow supergiant star was fully eclipsed on January 1, 2010.The nature of the eclipsing object has been a mystery, with the
Japanese intestines are adapted to sushi, says a new study that found genes from an ocean microbe in the gut bugs of long-term seaweed eaters. In the wild, the marine bacterium Zobellia galactanivorans feeds on Porphyra seaweed, which includes the seaweed species used to make sushi wrappers, or nori. Researchers were studying the microbe to find out which enzymes it uses to break down a carbohydra
Near-Death Experiences Explained?Bright lights, angelic visions products of too much CO2 in the blood, study says. Near-death experiences are tricks of the mind triggered by an overload of carbon dioxide in the bloodstream, a new study suggests. Many people who have recovered from life-threatening injuries have said they experienced their lives flashing before their eyes, saw bright lights, left t
In June 2000 scientists joined U.S. President Bill Clinton at the White House to unveil the Human Genome Project's "working draft" of the human genome—the full set of DNA that makes us human (quick human genetics overview). As the tenth anniversary of that achievement approaches, scientists weigh in on the scientific discoveries the Human Genome Project enabled, as well as some hopes and predictio

National Geographic Traveler contributor Andrew Evans recently spotted and filmed an all-black king penguin—a very rare mutant—on the sub-Antarctic island of South Georgia. © 2010 National Geographic; video: Andrew Evans RELATED Giant Penguins Once Roamed Peru Desert, Fossils Show "King Penguins" in National Geographic Magazine UNEDITED TRANSCRIPT This all black-feathered king penguin could be ‘on
Photograph by William Albert Allard, National Geographic Stock Global Warming Making People More Aggressive?Forget anger over leaked emails: Murders and assaults could jump by a hundred thousand cases a year in a warmer world, a new study says. Global warming could make the world a more violent place, because higher temperatures increase human aggression and create volatile situations, a new study
Earth's now steamy Equator was covered with ice 716 million years ago, according to a new study. The finding appears to add solid evidence to the theory of an ancient "snowball Earth." The discovery hinged on proving that the right rocks had been covered by glaciers in the right place at the right time. Study leader Francis Macdonald, an Earth scientist at Harvard University, and colleagues worked
Liberals, Atheists Are More Highly Evolved?Smarter people more inclined to nontraditional values, study suggests. Your apelike ancestors probably aren't top of mind when you enter the polling booth. But a new study suggests that human evolution may have a big influence on whether you're liberal or conservative—not to mention how smart you are, whether you believe in God, or whether you've got a ch
Like the vegetarian who can't resist the occasional burger, the otherwise herbivorous gorilla might succumb to cravings for its evolutionary cousins, a new study hints. While some zoo specimens are known to eat meat, wild gorillas eat only plants and fruit, along with the odd insect—as far as scientists know (see video of wild gorillas feasting on figs). But a recent study found DNA from monkeys a
Exposed ChurchYou might call it an act of God. A severe drought in Venezuela has exposed a church—pictured in 2008 (left) and on February 21, 2010—that had been inundated when a hydroelectric dam was built in 1985. The 82-foot-tall (25-meter-tall) church and the Andean town of Potosi (see map) were flooded to establish the Uribante-Caparo water reservoir to power the plant, which is currently oper

The shout goes up as a great shadow sweeps over our boat. The white-tailed eagle makes its descent to one of the 24,000 islands that make up Sweden's pine-covered, rocky Stockholm Archipelago.

King Solomon's Wall Found—Proof of Bible Tale?A 3,000-year-old defensive wall might be unprecedented archaeological support for a Bible passage on King Solomon. A 3,000-year-old defensive wall possibly built by King Solomon has been unearthed in Jerusalem, according to the Israeli archaeologist who led the excavation. The discovery appears to validate a Bible passage, she says. The tenth-century B
The drowning of a Florida SeaWorld animal trainer by "Shamu"—the stage name assigned to multiple SeaWorld captive killer whales—is not typical behavior for the whales, scientists say. (See a picture of another Shamu at the California SeaWorld.) "I don't think there's ever been a report of a killer whale attacking a human," said Wayne Perryman, a marine biologist at the National Oceanic and Atmosph
Eyeless Urchins "See" With SpinesSea urchin bodies act as big spine-covered eyes, according to researchers who created "Twilight Zone" conditions to test how well the marine creatures can see. The spiky body of a sea urchin acts as one big, spine-covered eye, confirms a new study that tested how well urchins can see. Sea urchins, like their close relatives the sea stars (starfish), don't technical
Scientists have finally solved the mystery of how one tiny creature has flourished for up to 50 million years without sex: it dries up. Bdelloid rotifers, microscopic asexual freshwater invertebrates (animals without spines) are the ultimate escape artists, able to outpace their enemies by drying up and blowing away. For most animals, sex is not only a way of producing the next generation, but a m
