White Blood Cells Vs Bacteria

Warzone: S. aureus bacteria escaping destruction by human white blood cells

White blood cells are at once the intelligence agents and the crack commandos of the body’s immune system. They’re the special forces that hasten to the scene of an attack whenever germs or infections are entering the body. Their mission: to take out invading pathogens, and generally to defend against infectious diseases and foreign substances – like potentially malevolent bacteria. Continue reading

10 Mystries About Universe

The Universe… The incredible difference in scale between the tiny world we live in every day and the vastness of all time and space begs the question of whether we will ever be able to grasp the fullness of the cosmos. But that doesn’t stop us from trying. In fact, contemplating the great unknowns must be one of the oldest hobbies in human experience. The pursuit has given rise first to religion, then to philosophy, then to people who make fun of religion and philosophy.

We may never understand the entire universe, but we can sure appreciate the fact that it’s so complex that it eludes us.

10. Extraterrestrial Intelligence

This is really a simple mystery. Is there other intelligent life out there in the universe? Carl Sagan reminds us that if we exist, then, no matter how rare intelligence is in the universe, given how huge the universe is, we must have many neighbors out there somewhere. Frank Drake, an astrophysicist, created an equation that helps figure out how much intelligent life there is in the universe, and estimated that if only one in a billion planets has intelligent life, then there must still be over 6 billion planets with intelligence on them. Enrico Fermi, however, pointed out that if life is that common, then it is virtually impossible that we haven’t yet detected any signs of other intelligent life in the universe. So, the real mystery is this: what is it about Earth that makes no one want to play with us?

20 Amazing Water Resistant Gadgets

Bubble O Seven – The Amphibious Car

Inspired by the James Bond Film “The Spy Who Loved Me”, the SQuba is an amphibious car designed by Frank Rinderknecht. The SQuba will operate like a boat if driven into the water, and is propelled along the surface by two propellers on either side of its license plate.

To submerge the vehicle, the driver opens a door to let water flood the passenger compartment. Once underwater, the SQuba uses a third engine to suck in water through the car’s front grille and pushes it out through two side jet vents.

The vents enable the car to manuevre underwater. The Lotus Elise-based SQuba is not for sale, but cost £750,000 to be built by Mr Rinderknecht’s company Rinspeed. It will go on show at next month’s motor show in Geneva, Switzerland. [ Via ] Continue reading
