the NYT article is better, but behind a registration wall. boo.

Scientists and the army team up, figure out what’s causing honeybee colony collapse.

Over the last four years, 20 to 40 percent of the honeybee colonies in the U.S. have mysteriously collapsed. The killer has remained unknown–until now. A team of entomologists, along with military scientists from the Department of Homeland Security, have a new prime suspect (or rather, suspects), as shown in a new report on the science website PLoS One. A tag-team of a virus and a fungus show every sign of being the culprit. Now it’s just a matter of eradicating that dastardly partnership.

Of course, just identifying the culprit is only the first step. The entomologists still have to find a way to stop the tag-team attack. It looks as though they’ll focus on the fungus, which is easier to block and defeat than the virus, and which, if defeated, should be enough assistance to help get honeybee populations back on track. And there’s always more to uncover–the tendency of the bees to wander off just prior to death is still a mystery (a University of Montana doctor actually uses the phrase “insect insanity” as a possible explanation), but that should all come in time.

The insect’s flight path can be wirelessly controlled via a neural implant.

The Army’s Remote-Controlled Beetle:

A giant flower beetle with implanted electrodes and a radio receiver on its back can be wirelessly controlled, according to research presented this week. Scientists at the University of California developed a tiny rig that receives control signals from a nearby computer. Electrical signals delivered via the electrodes command the insect to take off, turn left or right, or hover in midflight. The research, funded by the Defense Advanced Research Projects Agency (DARPA), could one day be used for surveillance purposes or for search-and-rescue missions.

The beetle’s payload consists of an off-the-shelf microprocessor, a radio receiver, and a battery attached to a custom-printed circuit board, along with six electrodes implanted into the animals’ optic lobes and flight muscles. Flight commands are wirelessly sent to the beetle via a radio-frequency transmitter that’s controlled by a nearby laptop. Oscillating electrical pulses delivered to the beetle’s optic lobes trigger takeoff, while a single short pulse ceases flight. Signals sent to the left or right basilar flight muscles make the animal turn right or left, respectively.

I love living in the future, it’s just. so. neat!

Alastair’s footage of inside the Raja theatre has been put up on YouTube.

I can’t tell if enthusiasm about Heart of the World is flagging because of the holidays or from the misconception that we’ve managed to get the down-payment together already. To clarify, we’ve raised the $48,000 deposit, not the $500,000 down-payment. Until we get it together, we’re dead in the water. I recommend writing anyone you think might be interested in financing the project. Every little bit helps.
