    Your phone is like a spy in your pocket

    Consider everything your smartphone has done for you today. Counted your steps? Deposited a check? Transcribed notes? Navigated you somewhere new?

    Smartphones make for such versatile pocket assistants because they’re equipped with a suite of sensors, including some we may never think — or even know — about, sensing, for example, light, humidity, pressure and temperature.

    How to rewire the eye

    A man who had been blind for 50 years allowed scientists to insert a tiny electrical probe into his eye.

    The man’s eyesight had been destroyed and the photoreceptors, or light-gathering cells, at the back of his eye no longer worked. Those cells, known as rods and cones, are the basis of human vision. Without them, the world becomes gray and formless, though not completely black. The...

    Studying a volcano in a war zone

    View the slideshow

    On clear nights a red glow radiates from the top of Mount Nyiragongo in the Democratic Republic of the Congo. On the mountain’s summit the source of the light thrashes and boils: the largest and most active lava lake in the world.

    Among volcanoes, Nyiragongo stands out. The magma that fuels its violent eruptions is incredibly fluid, capable of racing down the...

    Gray seals snack on harbor porpoises

    Two harbor porpoises (Phocoena phocoena) washed up on an eastern Belgian shore on September 24, 2011. The porpoises were still bleeding when they were collected, indicating that their deaths were recent. There were bite marks on the bodies, which scientists compared to the mouths and teeth of potential predators. The prime suspects, based on the necropsies, were gray seals (Halichoerus grypus...

    Hunting boosts lizard numbers in Australian desert

    The presence of humans rarely improves the lives of neighboring species. Yet a study shows that indigenous Australian hunters create prime habitat for a desert-dwelling lizard.

    “It’s simply not the case that human activity always has a negative impact on ecological circumstances,” says ecological anthropologist Doug Bird of Stanford University.

    The Martu, an aboriginal people in...

    As Erebus Lives and Breathes

    MCMURDO STATION, ANTARCTICA — Even when the December sun beats down 24 hours a day, most of Antarctica remains cold, if not brutally frigid. With one dramatic exception. Wind-blown clouds of steam rise year-round from a lava lake atop Mount Erebus, the planet’s southernmost active volcano.

    Borneo tough for red-haired vegans

    The near-vegan lifestyle of wild orangutans in Borneo’s forests means the apes face recurring protein droughts severe enough that their body tissues start to waste away.

    “They’re living on the margin,” says biological anthropologist Nathaniel Dominy of Dartmouth College.

    Borneo, one of only two natural habitats for wild orangutans, is predominantly forested with...

    Fertile Frontiers

    The solar system’s spotted bully and its ringed sidekick are holding some tantalizing treasures in their gravitational clutches. Circling Jupiter and Saturn are more than a hundred moons, including some of the most promising hosts for extraterrestrial life in the solar system.

    But not every one of these moons is an equal opportunity extraterrestrial...

    Farmer-ant sex scandal Ants heralded as thriving without males or sex turn out to practice sex after all in parts of their range.  Asexual animals intrigue biologists because these species are in the minority despite having the advantage that any individual, not just a female, can have babies. The ant Mycocepurus smithii forms all-girl farms that cultivate fungi as food throughout much of...

    BP spill: Gulf is primed to heal, but . . .

    Every day, Mother Nature burps another 1,000 barrels of crude into the Gulf of Mexico, along with additional quantities of natural gas. They enter from more than 1,000 widely dispersed natural seeps, deposits that University of Georgia oceanographer Samantha Joye has been studying for 15 years. Normally, these hydrocarbons don’t stick around long because local bacteria have evolved to eat...
