Birds perceive colour better than humans
Birds have enhanced vision acuity both by day as well as by night. This is necessary both to acquire a meal as well as avoid becoming a meal. Further, it is an added advantage while searching a for a suitable mate.

Oysters – Natural filters
Oyster is natural water filter. It could therefore, be used to clean our polluted water bodies cost effectively.

The Antikythera Mechanism
Two thousand years ago, a Greek mechanic set out to build a machine that would model the workings of the known Universe. The result was a complex clockwork mechanism that displayed the motions of the Sun, Moon and planets on precisely marked dials. By turning a handle, the creator could watch his tiny celestial bodies trace their undulating paths through the sky.

Mpemba effect
Under some conditions, hot water freezes faster than cold water. Scientists have long known that it can happen but have not been able to explain for sure why. In fact, it was first noted as early as the 4th century B.C. by Aristotle.

Ticks have a long life
Male African Ticks can live upto 4 years without food while females lived upto 8 years. With regular diet they could live upto 27 years.

Animals’ pupils come in different shapes and sizes

They also tend to have eyes on the front of their heads. Horizontally elongated pupils are nearly always found in grazing animals, which have eyes on the sides of their head. They are also very likely to be prey animals such as sheep and goats.

Human head transplant—possible?

Underwater Camouflage by Animals
Underwater camouflage is the set of methods that allows otherwise visible aquatic organisms to remain unnoticed by other organisms such as predators or prey.

Ultra-Black Fish
Scientists have discovered at least 16 species of ultra-black fish, each equipped with specialised skin that allows them to evade detection while hunting or hiding in the dark. Absorbing 99.95 percent of all photons, this blacker-than-black exterior creates a cloak of invisibility against the ocean’s dim backdrop. Even under a harsh spotlight, these creatures appear as mere silhouettes.

‘Super glue’ from snake venom can stop life-threatening bleeding in seconds
Kibret Mequanint, a Western University bioengineer and his international collaborators have found a novel use for snake venom: a body tissue ‘super glue’ that can stop life-threatening bleeding in seconds.

Ultra-Ever Dry
Ultra-Ever Dry is a superhydrophobic (water) and oleophobic (hydrocarbons) coating that will completely repel almost any liquid. Ultra-Ever Dry uses proprietary nanotechnology to coat an object and create a barrier of air on its surface. This barrier repels water, oil and other liquids unlike any coating seen before.

Speed of light can be dropped to zero
Light, which travels at a speed of 300,000 km/sec in a vacuum, can be slowed down and even stopped completely by methods that involve trapping the light inside crystals or ultracold clouds of atoms.

Flying Dragons
