EARTH'S MOON is different from other moons. It is bigger and the composition is the same as that of the planet. So far, it was believed that the reason for this was that both the earth and the moon were formed together during the kJUHDW LPSDFWy %XW WKLV WKHRU\ GLG QRW H[SODLQ PDQ\ WKLQJV about the moon, such as the fact that if the moon condensed from a disk of material rotating around earth's equator, it should be in orbit over the equator. Instead, the satellite's orbit is tilted five degrees off the equator.

that assist patients with heart, liver and other organ disease have one impediment—bacteria that form infectious biofilms on those devices not only sabotage their success, but also contribute to the rampant increase in antibiotic resistance. Now researchers have created self-healing slippery surface coatings with medical-grade teflon materials and liquids that prevent biofilm formation on medical devices, while preserving normal innate immune responses against pathogenic bacteria.
