Fishy behaviour
Survival of silvery fishes like sardines depend on their ability to reflect maximum light and remain nearly invisible to predators. But it is well known that reflective surfaces polarise light, a process which should have made the fish visible. The fish owe their survival to the presence of two types of crystals in their skin.

BEYOND USUAL SUSPECTS
A case for neglected species in wildlife research and conservation
For most of us wildlife is represented by large mammals like elephant, rhino, lion and tiger, may be birds like hornbill, raptors, peafowl and waterfowl and awe inspiring reptiles like marine turtles, crocodiles, python and king cobra. The fact is that wildlife ranges from very small insects to gigantic trees and from coral polyps to whales. Unfortunately, only a very small number of species have received attention of researchers and conservationists. While charismatic species largely drive the conservation scenario, they also seem to be the focus of wildlife research mainly because of the availability of funds and the role of charismatic species in setting our wildlife policies.

long before the birth of Christ, a bird, never seen before in the valley of the Blue Nile, reached the court of the pharaohs. Neither the architectural grandeur of the court nor the 'gold-draped' Pharaohs could silhouette its beauty. A bright red comb rested regally on its head and shiny green and red feathers clothed its body finally ending in an eclipse plume. The Egyptians had never seen a bird which laid so many eggs. When it crowed, they listened with rapt attention.

Chemical alert
Occupational exposure to a chemical used in dry-cleaning solutions and to degrease car parts raises the risk of Parkinson’s disease six-fold. Scientists linked Trichloroethylene to the brain disorder after studying 99 sets of twins. One in each pair was a sufferer of the illness, which can cause limb tremors. The US Environmental Protection Agency says the chemical is a carcinogen. Annals of Neurology, November 14 (online)
