Rotating Skyscraper

It’s the first building in the world that rotates, moves, and changes shape..The Dynamic Tower ., also known as Dynamic Architecture Building (Da Vinci Tower).Height 420-metre (1,378 ft), 80-floor moving skyscraper in Dubai, United Arab Emirates, designed by architect David Fisher.Similar to the Suite Vollard completed in 2001 in Brazil, Each floor will be able to rotate independently.This will result in a constantly changing shape of the tower. Each floor will rotate a maximum of 6 metres (20 ft) per minute, or one full rotation in 90 minutes.It will be the world's first prefabricated skyscraper with 40 factory-built modules for each floor.
Speciality:The entire tower will be powered from wind turbines and solar panels. Enough surplus electricity should be produced to power five other similar sized buildings in the vicinity.
The turbines will be located between each of the rotating floors.They could generate up to 1,200,000 kilowatt-hours of energy. The solar panels will be located on the roof and the top of each floor.Each of the towers have been designed with swimming pools, gardens and even lifts for cars meaning people can park outside their flats.
The Italian architect has revealed the ambitious plans to create Dynamic Towers in cities around the world with separate floors that spin 360 degrees around a concrete centre every 90 minutes. 
The first two are planned to be built in Dubai and Moscow with other cities including London, Milan, Paris, Rome, New York and Miami  on the cards too.
The 80-storey Dubai tower cost around £355million while the 70-storey Moscow tower will be developed by the Mirax Group with final costs unknown.

Talking tree












    We know for sure that trees talk through the air like we do, we have to wonder what they say about us as we press into their territories and begin to deforest the land, starting at one edge of the woods and working our way through to the other. Do the trees cut first shout to the others on the opposite end to run? Or are they whispering to us, asking that we be more mindful of the consequences?

We’ve known for a long time that plants are sensitive to their environments, reacting to changes in temperature, soil conditions, and light. Their senses, like ours, are quite developed: The Venus flytrap catches its dinner by snapping shut when an insect touches the tiny hairs on its leaves, and some farmers believe that sounds louder than the human voice stimulate the germination and rapid growth of some vegetables. But the confirmation that plants of the same species are able to talk with each other through the air is a new development.
In one recent research project, scientists took note of when the first gypsy moth larvae landed on a mature oak tree that resided in a grove with other oaks. By analyzing the chemistry of the mature oak tree’s leaves, they were able to determine that within a very short period of time, the tree had added a bitter tannin to all of its leaves. The tannin made the tree an unattractive lunch option for the gypsy moth larvae. But what was more astounding was that all the other oak trees in the grove changed the chemistry of their leaves, too, making them unappetizing as well.
It took a few years for the scientists to understand just how the trees in the rest of grove had gotten word that the gypsy moths were in town. It was found that the trees did not communicate through their roots — instead, they released a special gas (or pheromone) to warn their neighbors of the danger.
If we’ve ever walked in a forest or a grove on a breezy or windy day, we’ve probably experienced that bit of an unsettling feeling that says to you that the trees are “talking” above our head. With every moan and retort of the wood, we’d almost swear that we could hear rumblings. 
The trees surrounding we on our walk seem to be whispering to each other about the propriety of our presence.Turns out that our intuition may not be so far from the truth. Scientists are now discovering that plants have similar senses to ours and that they “talk” to each other — not through their roots, but as we do: through the air.It’s not only the oak trees that are chatting. We now have proof that willows, too, are talking with each other through the air. Quercus phellos (willow oak) is a deciduous tree in the red oak group of oaks. It is native to eastern North America from southern New York (Long Island) south to northern Florida, and west to southernmost Illinois and eastern Texas. It is most commonly found growing on lowland floodplains. It is a medium-sized tree growing to 20-30 m tall.

Fighting Fish


Fighting Fish.. known as the betta (Betta splendens). Bettas sometimes require a place to hide, even in the absence of threats. They may set up a territory centered on a plant or rocky alcove, sometimes becoming highly possessive of it and aggressive toward trespassing rivals.Two male Siamese fighting fish will fight to protect  territory. Male and female Siamese fighting fish should not be housed together unless it is for the purpose of breeding. They are likely to become aggressive with each other either before or after breeding. The aggression of this fish has been studied by ethologists and comparative psychologists.These fish have historically been the objects of gambling; two male fish are pitted against each other in a fight and betsare placed on which one will win. One fish is almost always killed as a result. To avoid this, male Siamese fighting fish are best isolated from one another. Males will occasionally even respond aggressively to their own reflections in a mirror.Though this is obviously safer than exposing the fish to another male, prolonged sight of their reflection can lead to stress in some individuals. Not all Siamese fighting fish respond negatively to other male fish, especially if not too many of them are present.       The Siamese fighting fish is a species in the gourami family which is popular as an aquarium fish. In January 2014 a large population of the fish was discovered in the Adelaide River Floodplain in the Northern Territory, Australia. usually grows to a length of about 6.5 cm (2.6 in). Although aquarium specimens are known for their brilliant colors and large, flowing fins, The natural coloration of B. splendens is a dull green, browns, and gray, and the fins of wild specimens are relatively short. Some people of Thailand and Malaysia are known to have collected these fish prior to the 19th century from the wild.In the wild, bettas spar for only a few minutes or before one fish backs off. Bred specifically for fighting, domesticated betta matches can go on for much longer, with winners determined by a willingness to continue fighting. Once one fish retreats, the match is over. Seeing the popularity of these fights, the king of Thailand started licensing and collecting these fighting fish.

Twinkle Stars

In a dark, clear, moonless night.We look up into the sky.We see thousands of stars arranged in patterns or constellations.The light from these stars has traveled great distances to reach Earth. But what are stars? How far away are they? Are they all the same? Are there other planets around them? When stars initially form from large balls of gas, they contract under the influence of gravity, and heat up because that gravitational energy goes into the motion of the gas.Stars get their heat from two sources - gravity, and nuclear fusion.Once they get hot enough, the hydrogen nuclei in the plasma in the center of the star start to occasionally merge to form helium, releasing a lot of energy from that nuclear fusion process. All this heating, from both sources, creates a pressure that causes the star to quit contracting at some point.
If the star is big enough to start with, the central temperature will be high enough to really keep that fusion going, and the heat gradually will seep out to the outside parts of the star, so the outer surface regions will also rise to quite high temperatures. We all know how important it is that our Sun gives us light! But, why does this happen? To understand, we need to look at the structure of stars.
What causes stars to shine?
Because stars are so massive, the density and pressure in the cores are extremely high! It is the temperature of the outer surface that determines the way the stars shine - our sun has an outer temperature of around 5000 degrees, but other stars can be as hot as 50,000 degrees, producing much bluer light, while red dwarf stars are considerably cooler and produce mostly red and infrared light. The process that causes stars to shine is the same one that we have harnessed for use as a weapon: nuclear fusion.Stars start as huge regions of gas, mostly hydrogen. This gas will start to contract, and it heats up. In fact, the Sun's core is so hot and has such high pressure that it undergoes nuclear fusion. Fusion is the combining to two lightweight elements into a heaver element. In our Sun, the core converts hydrogen into helium. This conversion of hydrogen into helium is the first reaction that happens in every star, it is called the main sequence. This reaction actually ends up with a surplus of energy according to the equation E=mc2. This is because the mass of the combing hydrogen is greater that the end product of helium. Therefore, the mass is converted to energy, and that energy is the electromagnetic radiation (light) that we get.
