The dual nature of light, as in the fact that it can act like both a particle and a wave, has had physicists puzzled since that was first discovered. Such a duality was bound to lead to some paradoxes, scientists hypothesized at the time, and now their predictions appear to be coming true. Scientists have recently di... |

When speaking about pollution, carbon dioxide, soot and methane are usually regarded as being the worst of its kinds. These particles are fairly small and, in addition to ruining the atmosphere, also have the ability to ruin people's lungs and lives. Because the public eye has been focused on combating these typ... |

Doctors and health experts have been amazed by how fast and efficient the skin repairs itself since the dawn of time. Within just a few days, superficial scratches to the skin are healed without any trace, and with no scars. Special mechanisms inside the skin contribute to this effect, and experts have been looking f... |

Physicists observed nanoscale bubbles of air forming in water for the first time in 2001. The only problem is these bubbles were not supposed to exist. Still, they continue to contradict the laws of physics and pop up unexpectedly.Air can form bubbles in water and these can last for a long time until breaking. The p... |
