Hanging baskets of sex and death help fruit growers
A hanging basket style device is at the heart of a plan by researchers at the University of Warwick to harness the sex drive of a major pest of fruit orchards as a weapon to spread a virus to kill that very same pest. The device allows growers to selectively target the pest with a virus that kills its larvae without killing other beneficial insects.

Researcher says Halloween no laughing matter for many youngsters
Halloween may seem like so much harmless fun, a time when adults enjoy laughing in the face of death, and implore their young children to do the same. According to a Penn State researcher, however, the humor of tombstones, monsters and other scary elements is often lost on kids at the ripe age of 6 or 7 -- many of whom don't find the holiday the least bit funny.

Dartmouth Flood Observatory tracks the aftermath of Katrina
Researchers with the Dartmouth Flood Observatory have been working to help map and analyze the flooding that has occurred as a result of Hurricane Katrina. The maps not only provide an overview of the impact and enormity of the flooding, they also preserve a day-to-day record of this flood to be analyzed in the coming months. The images will also be archived to support research into global flooding trends and climate change.

UCR biochemist goes to Washington with high-protein corn
Daniel Gallie, professor of biochemistry at UC Riverside, will present his research on high-protein corn before a congressional committee in Washington, D.C., Sept. 23. The research holds promise for efficiently feeding such corn to people and livestock all over the world. Gallie's research on doubling the protein content of corn grain adds significant value to the crop, benefiting corn producers. Moreover, his technology nearly doubles corn oil, the most valuable content of corn grain, and significantly increases the grain's value.

Two-thirds of meta-analyses in the critical care literature are of poor quality
More than two thirds of meta-analyses available to critical care physicians have major methodological flaws and cannot be reliably used to guide clinical practice. Research published today in Critical Care concludes that the overall quality of meta-analyses in this field is poor, but has improved over time, possibly due to the publication of the Quality of Reporting of Meta-analyses statement (QUOROM) in 1999.

Lethal needle blight epidemic may be related to climate change
Biologists present strong evidence in the September issue of BioScience that a lethal outbreak of needle blight that is killing lodgepole pines in British Columbia is caused by climate change. The blight, caused by the fungus Dothistroma septosporum, causes trees to loose their needles and eventually die. Lodgepole pines are an economically important species, being used in construction and for pulp.
