In its ability to learn, the cockroach is a moron in the morning and a genius in the evening.
Dramatic daily variations in the cockroach's learning ability were discovered by a new study performed by Vanderbilt University biologists and published online this week in the Proceedings of the National Academy of Sciences.

Researchers at the University of Illinois have used an innovative approach to reveal the molecular basis of altruistic behavior in wasps. The research team focused on the expression of behavior-related genes in Polistes metricus paper wasps, a species for which little genetic data was available when the study was begun. Their findings appear today online in Science Express.
Like honey bee workers, wasp workers give up their reproductive capabilities and focus entirely on nurturing their larval siblings, a practice that seems to defy the Darwinian prediction that a successful organism strives, above all else, to reproduce itself. Such behaviors are indicative of a eusocial society, in which some individuals lose, or sacrifice, their reproductive functions and instead work to benefit the larger group.

Stable flies are the latest suspect that may be involved in the West Nile virus deaths of hundreds of pelican chicks at the Medicine Lake National Wildlife Refuge in northeast Montana. West Nile virus killed 800 to 1,000 pelican chicks in 2003, averaged 400 in each of the next three summers and more than 600 this year.
|The Medicine Lake National Wildlife Refuge contains the fifth largest colony of American white pelicans in North America.
Veterinary entomologist Greg Johnson of Montana State University said earlier this year that he considered the possibility that lice were transmitting West Nile virus to pelicans. He became suspicious after collecting very few mosquitoes in 2006, but seeing pelicans continue to die at a high rate. Johnson discovered previously that the Culex tarsalis
mosquito is the primary carrier of West Nile virus in Montana and that the Medicine Lake refuge was one of the hot spots for the virus.

Some of the world's biggest greenhouse polluters took aim at President George W. Bush on Friday, calling him "isolated" and questioning his leadership on the problem of global warming.
Bush, who convened the two-day meeting of the 17 biggest emitters of climate-warming gases, stressed new environmental technology and voluntary measures to tackle the issue.

Officials coping with a severe drought in eastern Alabama and western Georgia issued sweeping bans Friday on outdoor watering and scrambled to secure a dwindling supply of drinking water to more than 50,000 people.
Divers went into Lake Martin looking for ways to increase the depth around intake pipes that drain water from the massive lake into the water system for Alexander City, 44 miles northeast of Montgomery on the Georgia line. Lake Martin is the only source of water for the Alexander City system.
