Swedish cities could connect via bike superhighway

In Sweden, city planners and the country's traffic authority are looking into building a four-lane bike superhighway between the university town of Lund and Malmö, Sweden's third-largest cities and one of its most diverse.

Cities like London have invested in protected lanes that they call “bike superhighways,” but this one would be one of the first to connect two cites (you know, like an actual highway). The designs for the trail have it following the path of railway tracks, protected from wind by fences and hedgerows.

Watch an orca chase a shark out of the water

Orcas might be charismatic movie stars, but they are also killer whales. A family of beachgoers in New Zealand caught on film an orca fighting with a few sharks. One shark was so eager to get away from the whale that it beached itself in the shallow water.

Tragic death leads to energy conservation

Four years ago, a 14-year-old girl touched a fence in a city park in Baltimore and was instantly hit with a lethal 227 volts of electricity. An exposed underground power cable happened to be touching the fence, just one example of hundreds of sites throughout the city that are still "pulsing with potentially deadly stray voltage," according to WJZ, the city's CBS affiliate.

Cap-and-trade scheme for whaling to be almost as popular as the other kind

Scientists proposed in the journal Nature that one way to save whales is to allow people to hunt them. (The current approach is a "ban" on hunting, but 33,500 whales have been killed since it went into effect 25 years ago, so it's not exactly working, reports Bruce Barcott at OnEarth.)

It sounds nuts, but there's a catch: only so many whales could be hunted every year, and everyone could buy and sell the right to hunt them on a cap-and-trade-style market, like the kind that Europe uses to regulate its carbon emissions.

Don’t believe the hype about the ‘molecule that could solve climate change’

Some chemists came up with a really clever way to observe the intermediate stage of an atmospheric chemical reaction, and then some PR flack got a hold of it and suddenly science has invented a brand-new molecule that will solve all our climate change woes! As usual, things that seem too good to be true probably are.
