اقرأ المقالIn January 2016, Professor Mike Brown, the California Institute of Technology researcher who demoted Pluto to dwarf status, reported that he and some colleagues had discovered evidence of a ninth planet in our solar system. Dubbed Planet X, the gaseous giant believed to be two to three times the size of Earth, purportedly has a highly elliptical orbit and takes over 20,000 earth years to revolve around the sun. Though exciting, the find was based on computer simulations, which means that no one has ever seen this mysterious planet.
اقرأ المقالThe fact that the Dionaea muscipula, or Venus flytrap, feeds on unsuspecting insects by luring them into its jaw-like leaves with sweet-smelling nectar has been known for centuries. However, scientists thought the prey only provided the plant with essential nutrients like nitrogen and phosphorous that are severely lacking in their native habitats – the subtropical wetlands of North and South Carolina. They had assumed that like other vegetation the carnivorous plants obtained their energy through photosynthesis – using light energy to convert carbon dioxide and water into sugar and oxygen. It turns out they were wrong.

اقرأ المقالUnmanned aerial vehicles, or drones, have tremendous potential to deliver emergency supplies to remote or disaster-struck regions. However, they are expensive to mass produce and often require special pads to launch and land safely. Additionally, the need for the aircraft to maintain enough battery life to return, cuts the delivery distance to half. But these issues may be history, thanks to an affordable and disposable drone that is designed for a one way journey.

However, last week’s simultaneous stranding of two pods, totaling over 650 pilot whales, in the shallow muddy waters of Golden Bay at the northwest tip of South Island is almost unprecedented. Local marine experts say it is the largest known whale stranding since 1985 when 450 of the mammals were found beached in Auckland, and the third largest on record.
اقرأ المقالIn retrospect, 2016 was a banner year for exploding devices.
