A pair of German physicists claim to have broken the speed of light — an achievement that would undermine our entire understanding of space and time.
The scientists were investigating a phenomenon called quantum tunnelling, which allows sub-atomic particles to break apparently unbreakable laws.

Most the times I have a problem with a web page loading slow (or freezing temporarily), I look down at the status bar and see that it is waiting on an ad server, google analytics, or the like.
It seems to me on popular web sites the bottle neck is overwhelmingly on the ad servers now and not on the servers of the main web site itself. In my opinion it seems we need a better model for serving ads or else these services need to add more servers/bandwidth.
Are there any studies on the delay that 3rd party ad servers are creating, or any new models that are being introduced to serve ads?

CNN is running a story about the discovery of one of the last ocean currents near Tasmania. From the article:
New research shows that a current sweeping past Australia's southern island of Tasmania toward the South Atlantic is a previously undetected part of the world climate system's engine-room, said scientist Ken Ridgway.
The Southern Ocean, which swirls around Antarctica, has been identified in recent years as the main lung of global climate, absorbing a third of all carbon dioxide taken in by the world's oceans.

According to a National Geographic Article certain fungi can use ionizing radiation to perform "radiosynthesis" using the pigment melanin (the same one in our skin that protects us from UV radiation). It is speculated that this might be useful on long space voyages where energy from the Sun is not readily available.
