Scientists at Stanford say they’ve invented the first high-performance aluminum battery that’s “fast-charging, long-lasting and inexpensive.” It would solve many of the problems with lithium-ion and alkaline batteries. This seems to be a major breakthrough.
The aluminum-ion battery, made of aluminum and graphite in a liquid pouch, offers some potentially huge advantages. They ...

Google is lately developing a ew interaction sensor that can track movement with extremely high accuracy, named “Project Soli”. The goal of this attempt is to harness the power of hand and finger manipulation to make it easier to interact with ever-smaller devices and screens.
They are on their way to create something that let ...

Discovered in 1930, Pluto was long considered our solar system’s ninth planet. But after the discovery of similar intriguing worlds deeper in the distant Kuiper Belt, icy Pluto was reclassified as a dwarf planet.

Since the bicycle was invented, scientists have postulated various reasons as to why a bicycle is self stable above a certain speed. The consensus has been that a bicycle’s stability is related to two factors: First, the rotating wheels of the bicycle provide stability through gyroscopic effects. Secondly, that the ‘trail’ plays an important ...

The Chernobyl station was situated at the settlement of Pripyat, about 65 miles north of Kiev in the Ukraine. Built in the late 1970s on the banks of the Pripyat River, Chernobyl had ...

On January 5, 1933, construction begins on the Golden Gate Bridge, as workers began excavating 3.25 million cubic feet of dirt for the structure’s huge anchorages. Four years later, on opening day (May 27, 1937) 200,000 bridge walkers marveled at the 4,200-foot-long suspension bridge, which spans the Golden Gate Strait at ...
