2. How beetle getting water in the desert?
Windblown water (blue arrow) becomes a drink for a carefully positioned Namib
Desert beetle. Facing into the breeze, with its body angled at forty-five degrees, the
beetle catches fog droplets on its hardened wings. The droplets stick there to
hydrophilic bumps, which are surrounded by waxy, hydrophobic troughs. Droplets
accumulate and coalesce until their combined weight overcomes the water's attraction
to the bumps as well as any opposing force of the wind; in a ten-mile-an-hour breeze,
such a droplet would stick to the wing until it grows to roughly two-tenths of an inch
in diameter; at that point it would roll down the beetle's back to its mouth parts,
quenching a desert thirst.

3. Blood coagulation in space
In Blood coagulation the most important property is self repair mechanism

Scientist trying to mimic this property to create self repairing polymer.
One of the type is FRP, Its successful material which is used in aircraft.

4. Application on lotus effect
The microstructures present in the lotus ,preventing lotus from sticking with water.
This principle is used to develop different type of materials ,which not sticky with water.
If this type of materials used over submarine, its reduce the impact of water and help to
increase the speed
