What did Richard Feynman Invented
RICHARD FEYNMAN WAS not your typical scientist. The American theoretical physicist had a penchant for picking safes, was a capable bongo player and made no secret of his fondness of strip clubs where he scribbled equations on napkins between performances. But Feynman wasn’t just a wacky academic, generating inconsequential theories.
Do All Nails Grow Same Rate
Each individual nail grows at its own pace. Usually, the longer the outermost finger joint, the faster the nail grows. The nail of the index finger thus grows quickly, while the thumbnail grows the slowest, as the thumb lacks the central of the three ordinary finger joints.
Mysterious Nodding Disease in Uganda Attack Young People
In 2009, the centers for Disease Control and Prevention (CDC) received a plea from officials in Uganda: Could the agency investigate a mysterious head-nodding disease spreading among more than 3.000 young people there? Healthy children would suddenly begin to nod their heads uncontrollably, sometimes falling into a trancelike state. The incidents seemed to be triggered …
Is There Alien Life on Earth
If you could take a cell from any organism—an alga, giant sequoia, condor, or your second cousin—and dive through its membrane into its clear liquid cytoplasm interior, you would find that all life as we know it shares the same building blocks. Familiar amino acids and proteins initiate and accelerate the same chemical reactions in …

Although French student Ernest Duchesne noted the growth of penicillin in 1896, its true potential was not realised until Scottish scientist Alexander Fleming rediscovered it in 1928. He noticed that colonies of the bacterium Staphylococcus aureus failed to grow in areas of a culture that had been contaminated by the green mold Pénicillium notatum.

Supernatural mind control, placebo effect or something in between? Hypnosis takes us on a journey into the mind… In its simplest terms, hypnosis is a process by which someone becomes less aware of conscious thought and inhibition, and more open to suggestion.

Why do People get Motion Sickness
Balancing what your eyes see with what your ears sense can be tricky when you’re on the move. A collection of nerves, channels and fluid called the vestibular system inside your ears co-ordinates equilibrium by detecting motion from sensory inputs when moving.
How does an Embryo Develop Into a Fetus
After fertilization, the single-celled zygote splits into two, then the two cells double to four, four to eight and so on. The journey along the Fallopian tube is quite slow, while growth continues. On its way, the zygote divides to make a clump of 32 cells, known as the morula stage. If the early embryo …
