There is not a lot of research that has been done on the evolutionary origin structure - this is one of the many mysteries of the Amazon you can c ...

These amazing images of animals in the womb were compiled by scientists using ultrasound scans and computer graphics.

Scientists at University of St Andrews in Scotland and the Institute of Scientific Instruments (ISI) in the Czech Republic have designed a minute but completely functional tractor beam.

Reminiscent of Star Trek, they use a beam of light to draw objects towards the light source on a microscopic level.

The LifeStraw removes nearly 100% of waterborne bacteria and can filter up to 1000 L of water.


Throughout the world, an estimated 884 million people still do not have access to clean sources of water. According to the LifeStraw manufacturers, the device contains no chemicals or batteries and makes it possible to drink safely from any river, lake or puddle.
