Being a good driver is no more the sole criterion for getting a driving license… at least not in Britain. One has to show that he or she can be environment-friendly too by simply using fuel effectively. The British government has declared that from now fuel efficiency of teh vehicle would be made part of the driving test to help reduce polluting emissions, and to save money on energy bills.

We all know that bats, whales and dolphins use Ultrasound energy to communicate with each other. A new member has entered the
list- a rare Chinese frog, Amolops tormotus, that lives alongside fast-flowing streams in Anhui Province, China. Its unique ultrasonic (greater than 20 kilohertz) calls can be heard beyond the spectrum of the background hubbub of running water!

In ancient times, Indian astrologers used the sky maps to determine the calendar and seasons of the year. They gave precise information on sun rise and sun set.. Scientists have recently discovered a 500 BC sky map in Hyderabad, India. The map is probably the oldest in Asia and was carved out by megalithic Indians with astounding accuracy. This ancient map represents the Saptarishi Mandal or the Great Bear (Ursa Major), which has for ages been used to track the North, one of the four Cardinal directions. |

Amazon ants (red ants found in the western US.) raid nests of certain black ants and carry back the cocoons and larvae to their own homes. When the cocoons hatch, the newborns become the slaves of these army ants and do all their work. The slave ants build homes for and feed the Amazon ants, who can do nothing but fight. They depend completely on their slaves for survival.

Did you know that the insect eye is possibly the most complex miniature structure, as it is made of thousands of minuscule lenses? Enthused by this fact, the researchers at the University of California, Berkeley, have developed an artificial insect eye containing over 8,500 hexagonal lenses packed into an area the size of a pinhead. The dome-shaped structure would be used in tiny, omni-directional surveillance devices, ultra thin cameras, and high-speed motion sensors. It might have medical applications and could even help develop artificial retinas for the blind. |
