Mars is not far
Issue Date: Jun 30, 2013
How far is Mars from Earth? A common response would be, billions and billions of miles away. The site being reviewed gives the answer in a rather fun way: a pixel-by-pixel journey from Earth to Mars which takes place in your browser.

Saviour saliva
A simple habit of sucking their toddler’s pacifier after it has fallen on the floor can help parents boost their kids’ immunity. Infants whose parents suck on the pacifier to clean it transfer microbes from their saliva to their children.

Live wire
Here is a wire you can stretch, bend or cut and it would still work. Scientists have created the self-healing, elastic wire using liquid metal and a polymer. Small tunnels are bored in polymer sheath and are filled with a liquid alloy of indium and gallium, forming a liquid metal wire inside the stretchable sheath.

Fault finding
“Stable” zones of the earth’s crust might not be so stable. These zones are more likely to cause massive earthquakes. It was thought that “stable” zones, where fault segments of the crust slip slowly, act as barriers to earthquakes and fast-slipping faults trigger them.

Joker in the pack of stars
Issue Date: Jan 15, 2013
Human beings have been fascinated with night and day skies ever since they have existed. Almost every civilisation has its stories on planets and galaxies. Even more fascinating are dead celestial objects. We, however, cannot see these objects. When stars start to die, they collapse and become almost infinitely dense. Their gravity increases to an extent where nothing can escape, not even light.

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.

Super disc
Typical compact discs (CDs) store 600-700 megabytes (MB) of digital data. A new technology can now help develop CDs that can hold 2 terabytes or 2,000,000 MB of data. Instead of packing more data on the surface, the idea is to make an optical film with 64 data layers.
