An iceberg in or just outside the Ilulissat fjord, which likely calved from Jakobshavn Isbrae, the fastest glacier in western Greenland, in May 2012. Polar ice sheets are now melting three times faster than in the 1990s.

Climate change will make commercial shipping possible from North America to Russia or Asia over the North Pole by the middle of the century, a new study says.
Two researchers at the University of California ran seven different climate models simulating two classes of vessels to see if they could make a relatively ice-free passage through the Arctic Ocean. In each case, the sea routes are sufficiently clear after 2049, they say.
This image represents a chunk, or "cube," of brain. Each different color represents a different neuron, and the goal of the EyeWire game is to figure out how these tangled neurons connect to each other. Players look at a slice from this cube and try to identify the boundaries of each cell. It isn't easy, and it takes practice. You can try it for yourself at eyewire.org.

Daniel Berger, a researcher at MIT, traced these neurons using the EyeWire game.
In the EyeWire game, participants identify different neurons by coloring in their shapes using a Web-based 3-D interface.
People can get pretty addicted to computer games. By some estimates, residents of planet Earth spend 3 billion hours per week playing them. Now some scientists are hoping to make use of all that human capital and harness it for a good cause.
Right now I'm at the novice level of a game called EyeWire, trying to color in a nerve cell in a cartoon drawing of a slice of tissue. EyeWire is designed to solve a real science problem — it aims to chart the billions of nerve connections in the brain.
A mashup of innovation and old-school hacking (though none of the participants was bent on doing harm, we're assured), the goal of the competition was to improve the nation's health system and help people navigate the complexities of the Affordable Care Act.
A child born with HIV has been cured of the virus, researchers say. Audie Cornish talks to Richard Knox about what was different about this child among the millions who've been treated in the past and what it means for the prospect of an HIV cure in adults.
Audie Cornish talks with Laura Sydell for a preview of South by Southwest Interactive. The tech event, one of the most popular showcases for tech startups and emerging technologies, starts later this week in Austin.
And now for the Opinion Page. Technology has always promised to fix our imperfections. In this 1950s TV ad, G.E. swore that a new refrigerator-freezer combo would make a housewife's problems disappear.
