What it means to own something in the digital age is being re-negotiated.
Few of us own the music we listen to or the movies we watch in exactly the same way we did a decade ago. And today if you buy a smartphone from a cellphone company, what you can legally do with it — how and where you can use it — may be proscribed even if that phone is fully bought and paid for.
I keep a lot of music on my phone. I have the Stones, Janis Joplin and OK Go.
Benjamin Franklin said the only certain things are death and taxes. Let's add a third thing: Interviews. At many points, starting with school admissions or a new job, you're going to sit down before someone else and answer their questions.
Which is what NPR's Shankar Vedantam is about to do with us because he's got some new research relating to this topic. Hi, Shankar.
SHANKAR VEDANTAM, BYLINE: Hi, Steve.
INSKEEP: And let's begin this interview. What's the new research about?
What it means to own something in the digital age is being re-negotiated. Few of us own the music we listen or the movies we watch, in the same way as we did a decade ago. And today, if you get a smartphone from a cell phone company what you can legally do with it - how and where you can use it - may be restricted, even if that phone is fully bought and paid for.
NPR's Steve Henn explains. And we'll also find out a little bit about his music taste.
A new study of Central African forest elephants has found their numbers down by 62 percent between 2002 and 2011. The study comes as governments and conservationists meet in Thailand to amend the Convention on International Trade in Endangered Species.
Forest elephants in central Africa are being slaughtered in record numbers. The most comprehensive study ever, done over a decade, shows that poaching — mostly for the Asian market for ivory — has put the forest elephant on the brink of extinction. Poaching has overcome laws and treaties to protect the species. The U.S. government and wildlife groups are struggling to slow the killing. A meeting in March of the Convention on International Trade in Endangered Species will focus on solutions. Audie Cornish talks to Christopher Joyce.
Federal stimulus money has helped cut the high cost of lithium-ion batteries, but not nearly enough to make electric cars affordable. Now there's an abundance of advanced battery manufacturers and not enough major companies to buy them. Many plants in the United States, South Korean, Japan and China that got government subsidies aren't producing many batteries, if at all. Three years ago Michigan's governor touted the state as the new battery capital of the world. There were five new advanced battery plants in the works, all of which were to get major tax breaks and some federal grants.
Lithium-ion batteries sparked a crisis for Boeing's Dreamliner 787 — but the crisis is not an unprecedented one. Four decades ago, a very similar transition to new battery technology in airplanes yielded similar problems. Audie Cornish describes what happened then — and what lessons might be learned as lithium-ion batteries become the next generation that power planes.

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.
