POPSComputer model of bees probes the hive mind Thenius believes the foragers may be picking up clues about the quality of sources from their interactions with receivers. If some foragers have found a bountiful new source, the receivers have more work to do, so average unloading times across all foragers increase. This delay might suggest the existence of a better nectar source than the one a given forager has been visiting. Similarly, receivers are sometimes already half-full from another bee's nectar when a new forager arrives, so a forager needs to unload to more than one receiver. If this occurs more frequently, it may also suggest that a richer nectar source has been found. To test this hypothesis, Thenius's team built a computer simulation of a hive containing 5000 independent virtual bees. Each forager started out visiting one of two different flower patches, but would switch destinations if it had to wait too long to be unloaded or was being serviced by too many receivers.

POPSStinging Tentacles Offer Hint of Oceans’ Decline The explosion of jellyfish populations, scientists say, reflects a combination of severe overfishing of natural predators, like tuna, sharks and swordfish; rising sea temperatures caused in part by global warming; and pollution that has depleted oxygen levels in coastal shallows. These problems are pronounced in the Mediterranean, a sea bounded by more than a dozen countries that rely on it for business and pleasure. Left unchecked in the Mediterranean and elsewhere, these problems could make the swarms of jellyfish menacing coastlines a grim vision of seas to come. “The problem on the beach is a social problem,” said Dr. Gili, who talks with admiration of the “beauty” of the globular jellyfish. “We need to take care of it for our tourism industry. But the big problem is not on the beach. It’s what’s happening in the seas.”

POPSThis is scary stuff.... ....gazillions of these things are taking over our oceans! This is one good way to disappear Bush. This article is a little long but once I started reading I couldn't stop. Man, we are really screwing up the planet.

POPSAfricanized Honeybees found in Louisiana Part of an experiment in Brazil in 1957 to increase honey production, a swarm escaped, and began heading North, while interbreeding with Western honeybees along the way, passing on a characteristic aggressive trait, which can make a swarm life threatening. There is both the threat due to their aggressive nature ( Pre-Emptive Strike?), and the threat to the entire beekeeping industry. Beekeepers in Full Body Armour, inside an industrial greenhouse, with robotic collection, and a hermetic seal. Unless we can find a way to make honey without bees.

POPSKenya battles swarms of Locusts Cute little buggers aren't they? Guess this is one species which is thriving with climate changes. The insects have always been the most adaptable.

POPSReturn of the giant jellyfish Jellyfish and squid populations are increasing worldwide as both warmer water and fewer fish limit their population. But these are particularly impressive!

POPSGetting out of a Jam with Jellies Kiminori Ushida and his team have found a viable component that can harvested from jellyfish. Dr. Ushida is right in stating that the cleanup of the jellyfish must be economically feasible, or the fisherman, who are the most vulnerable to the damage caused by the overpopulation of jellyfish populations, will not be able to live or keep their boats. I think this has positive environmental and economic applications all over the world where jellyfish populations are on the rise.

POPSThe End of Civilization The court's ruling sparked hundreds of thousands of Iowans in conventional marriages to line up before activist judges pleading for immediate divorces claiming they saw no reason to go on being married. In addition, rumors of large swarms of locust appearing over Polk County have been confirmed along with unconfirmed massive fissures appearing around the District Courthouse. Marshal law has been ordered and the 12 National Guard soldiers left in Iowa will be deployed to reestablish order. Video at 11!
