A barren, treeless island in the Arctic archipelago of Svalbard may prove to be the last, best hope of agriculture in warmer, more fertile parts of the world. The first batch of 100 million of the most important agricultural seeds were placed into the doomsday repository there today. The Svalbard Global Seed Vault is buried deep within a frozen mountainside near the Norwegian town of Longyearbyen that perpetually cools it to –18 degrees Celsius (–0.4 degree Fahrenheit) with or without permafrost. Built to withstand all foreseeable disasters, including a recent earthquake that was the biggest in Norwegian history, it has room to protect at least 4.5 million samples (2.25 billion seeds) in its three man-made caverns. |

60-Second Science: Nets Drive Evolution of Small Fish |
|
Scientific American
|
|
Being a big fish in a small pond is more likely to get you noticed. That’s good news if you’re, say, the best pitcher in your little league division. But it’s not so good if you’re an actual fish. Because bigger fish are the ones that tend to get caught. Not only is that bad news for the fish, but it may be bad for the whole fish population. Or so say scientists from Australia and Canada in the online edition of the Proceedings of the National Academy of Sciences. They find that fishing for the largest individuals targets the fastest growers, leaving behind their slower-growing counterparts. Which means that current fishing practices may favor the evolution of slower-growing fish. |
