Why Is Honeycomb in Hexagonal Shape?

It is widely believed that bees are very intelligent, because they can not only learn how to step over obstacles by themselves, but also learn it by observing others . As clever mathematicians, bees are capable of engaging in kind of waggle dance, by which they could make use of directionality and speed for [...]

Scientists Figure out Why the Amazon River Flows Backwards

The Amazon used to flow from east to west, just opposite to the present direction. The fact that the largest river on Earth reversed its direction is not a trivial thing, so the geologists have been trying to find out the cause for some time. Dr Victor Sacek from the [...]

A Crazy Guy Sticks His Hand in Liquid Nitrogen

Placed under normal atmospheric pressure, nitrogen could become a liquid between -210°C and -195.8°C (-346°F to -320.44°F). That is amazingly cold. You may remember that in your classroom, teachers demonstrated how to put different objects into nitrogen and then shatter them. Therefore, it would be considered a bad idea to shove your hand [...]

Tractor beam. This schematic shows how sound waves normally pushed an object away, in (a) and (b). But if they are aimed at an object as in (c), that is also appropriately shaped, the object can be pulled toward the acoustic source. Image credit: APS/Alan Stonebraker.

A Tractor Beam Made of Sound Waves Can Move Around Centimeter-Sized Objects

Tractor beams, also called as “attractor beams,” which can get an object closer to another distant one, do often appear in science fiction. Is it possible that we can really use them in our daily life? Earlier this year, scientists claimed that they had produced a type of tractor beam, [...]
