Alarm pheromone causes aphids to sprout wings
Chemical communication within insect species is often much more sophisticated than expected. When aphids are attacked by predators such as ladybird beetles, they release an alarm pheromone, (E)-â-farnesene, that has long been known to cause other aphids to walk around or drop from the plant. In a paper soon to appear in Ecology Letters, researchers at the University and Max-Planck-Institut...Bird song changes sound alarm over habitat fragmentation
Changes in bird song could be used as an early warning system to detect man-made ecological disturbances, new research published in the British Ecological Society's Journal of Applied Ecology has found. Although much previous research has focused on bird song and vocal mimicry, this is the first study to analyse the role played by habitat loss and fragmentation on song-matching. Ecologists...HIV/AIDS rates in Tijuana, Mexico increasing at alarming rate

The findings are based on data compiled by a team of researchers working in San Diego and Mexico to create a population-based model in order to estimate HIV infection rates....Infection 'alarm' yields clues to immune system behavior
Drawing on lab experiments and computer studies, Johns Hopkins researchers have learned how a common protein delivers its warning message to cells when an infectious agent invades the body. The findings are important because this biological intruder alarm causes the body's immune system to leap into action to fight the infection. Learning more about how this process works, the researchers said, c...Alarming decline in Nepal's rhinos and tigers in former Maoist stronghold
