Last summer’s floods in Pakistan displaced millions of people--and millions of spiders. Although spiders rarely migrate to trees during natural disasters, the flooding was so heavy and prolonged, they had to climb trees and remain there. According to University of Akron biologist Todd Blackledge, who studies web-weaving spiders, some spin new webs each day. After weeks, the dense layers of silk, seen here in Sindh province, covered the trees--a result of continuous web spinning by the eight-legged refugees.
Plant and human genome researchers have uncovered myriad pathways toward understanding health and longevity, determining genes that code for things like disease tolerance and nutrient needs. A new bug gene-sequencing project aims to do the same — only the goal is to find genomic Achilles’ heels, to help people kill insects more easily.
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.
