Rainbow Roses
The Rainbow roses were shaped by Dutch flower company owner Peter VanDe Werken, who formed them by developing a method for injecting natural pigments into their stems while they are growing to make a striking multicolored petal effects. The dye are produced from natural plant extracts and absorbed by the flowers as they grow. A particular procedure then controls how much color reaches each petal- with stunning results. By treating the stalk with natural pigments, Van De Werken has managed to make each petal a different color. The pigment is absorbed and travels to the petals where it modifies their hue.
Lighting is hotter than the surface of the sun
Lightning can be up to 18,000 degrees Fahrenheit, which is almost two times the surface temperature of the sun! If lightning is so burning, why is it that we get our energy from the sun? Though lightning is scorching hot, its radiant energy pales in comparison with the sun’s. Whereas it’s true that lightning can set a tree on fire, the distance to its target must be very undersized for it to feel the full heat of lightning. The sun’s core though is close to 15 million degrees Fahrenheit!
“Brinicle” The Icicle of Death
An unusual underwater phenomenon they called “icicle of death” has been filmed by BBC crew in Antarctica. This has equipped with high end time-lapse cameras, the group recorded salt water being excluded from the sea ice and sinking down to the ocean floor. The temperature of this brine is less than 0C, leading water to freeze in an icy casing called “brinicle.” When “brinicle” met the sea bed, a web of ice formed that froze the whole thing it touched, as well as sea urchins and starfish. The strange phenomenon was filmed for the first time by cameramen Hugh Miller and Doug Anderson for the BBC One series Frozen Planet. The icy phenomenon is mainly caused by cold, sinking brine, which is more-dense than the rest of the sea water. It forms a brinicle as it contacts warmer water below the surface. It’s a bit of a race against time because no-one really knew how fast they formed. The location underneath the ice offs the foothills of the volcano Mount Erebus, in water as cold as -2C – really not easy to access.

China's mysterious 'river of blood'
The
Yangtze River, China’s longest river, suddenly turned a red colour over
the last few days. As of yet, scientists are unsure as to why. Although the source of the problem is unknown, I think we can rule out a couple of possible explanations.
For instance, biological activity is often offered as a cause of
discolouration of water bodies. However, in this instance, I would be
inclined to say that this is not the problem. Intrusion of colour
causing bacteria is usually the result of a decrease in oxygen
concentration of a water body. But, as this is a river, and by
definition is free moving, a significant decrease in oxygen levels on
this scale is unlikely. I would also think an algal bloom is an unlikely
cause, the main microorganisms that cause large discolourations or “red
tide” are predominantly marine based, and of course, this is fresh
water.
On the other hand, one cause that could most certainly be valid is industrial pollution; the surrounding area of the river is home to China’s largest industrial centre. Since the phenomenon has happened so quickly, it is possible that it is the result of a large release of chemical dyes into the river at some point upstream. But this will not be confirmed till analysis is complete.
If it is not found to be the direct result of a pollutant release, I would be inclined to attribute the problem to Acid Mine Drainage. AMD, can occur when water flows over or through sulphur-bearing materials forming solutions of net acidity. It is mainly associated with abandoned coal mines and currently active mining. An iron percipitate is formed and is the cause of a red/orange discolouration. Of course, there are many other probable causes; the addition of red clay to the water is one. But, whatever the prognosis, this event shows how sensitive water bodies are to changes in their environment.

New Hover Vehicle Recalls ‘Star Wars’ Bike
A resurrected hover vehicle won’t fly
through dense forests as easily as the “Star Wars” speeder bikes from
“Return of the Jedi,” however its user friendly controls may one day
permit anyone to fly it without pilot training. The aerial vehicle
resembles a science fiction flying bike with two ducted rotors in place
of wheels, however comes from a design abandoned in the 1960s due to
balance and rollover problems. Aerofex, a California-based firm, set the
stableness issue by creating a mechanical system controlled by two
control bars at knee-level which allows the vehicle to react to a human
pilot’s leaning movements and natural sense of balance. Consider it as
lowering the threshold of flight, down to the domain of ATV’s
(all-terrain vehicles),” said Mark De Roche, an aerospace engineer as
well as founder of Aerofex.
This kind of automatic controls may
permit physicians to fly future versions of the vehicle to pay a visit
to rural patients in places without roads, or enable border patrol
officers to go about their duties without pilot training. Everything
comes about involuntarily without the need for electronics, let alone
complicated artificial common sense or flight software. It basically
captures the translations between the two in three axis ( pitch, roll
and yaw), and also triggers the aerodynamic controls needed to counter
the movement which lines the vehicle back up with the pilot,”
Since the pilot’s controlling movements
are reasonable and continuous, it performs out quite very easily to him.
But Aerofex would not plan to instantly develop and promote a manned
version. Rather, the aerospace firm observes the aerial vehicle as an
experiment platform for new unmanned drones — heavy-lift robotic
workhorses that may utilize the similar hover technology to work in
agricultural fields, or effortlessly provide supplies to
search-and-rescue teams in rough terrain. Perhaps the soldiers or
Special Forces may employ such hover drones to carry or deliver heavy
supplies in the constrained spaces between buildings in cities. U.S.
Marines have actually begun testing robotic helicopters to provide
supplies in Afghanistan.
The hovering drones will not fly as
successfully as helicopters due to their shorter rotor blades; however
their completely enclosed rotors have the benefit of a much smaller size
and protection near humans. They are really much less effective than a
helicopter, that has the advantage of larger diameter rotors,” De Roche
explained. “They have exclusive performance advantages, however; since
they have verified flight within trees, near walls and under bridges.
Aerofex possesses presently limited human flight testing to a height of
15 feet in addition to speeds of around 30 mph, however more out of
caution rather than due to any technological limits. Earlier versions of
the hover vehicles can fly about as quickly as helicopters, De Roche
said. Flight testing in California’s Mojave Desert led to the
presentation of a technical paper regarding Aerofex’s achievements at
the Future Vertical Lift Conference in January 2012. The firm ideas to
fly a second version of its vehicle in October, as well as make an
unmanned drone version for flight testing by the end of 2013.

Biggest 2012 Python Snake found 17-foot long found in Florida Everglades
Biggest Python Snake on the planet:
17-foot lengthy discovered in Florida Everglades, which is the biggest
snake discovered in 2012. The largest python on the earth is 17 foot
long and was prepared to lay 87 eggs. It was discovered in the Florida
Everglades and if you are scared of snakes, this creation will make your
Ophidiophobia even worse. The biggest snake of the python species is 17
foot and 7-inches in length, is weighs 164 pounds and carried 87 eggs
in its oviducts, that becoming the latest state record ! What happened
to the monster? Let’s find out together.
A group of research workers from Florida makes a very thrilling discovery! Indeed an enormous Burmese python, measuring 17-feet and 7-inches (5.3 meters) and weighing 164-1/2 pounds. Furthermore, the massive creature was pregnant with no less than 87 eggs. The creature was found was discovered in the Everglades National Park, and its dimensions shows precisely how well this Southeast Asian species is doing in South Florida.
This beautiful exemplary of the greatest Python was put to sleep and taken to the University of Florida for investigations as to what the species take in from the local fauna, also to discover a lot more about how they could put a stop to the increasing amounts of this killer species. This kind of snakes is constrictors, which means they kill their prey by coiling around it and chocking it to death.

The snakes are extremely difficult to
capture, which since they have established themselves in the Everglades,
they will soon be not possible to eliminate.
Home at the top of volcano valued $750000
a secluded house that provides privacy
for sale to the public. Distinctly, this home was constructed right over
top of the volcano off, in the desert in Southern California, the
United States.
This desert is between Las Vegas and Los Angeles in Newberry Springs,
San Bernardino, therefore the home was dubbed the Volcano House. The
proprietor, Huell Howser, complete with a home area, amounting to 60
hectares. As host of the demonstrate traveling California’s Gold is
marketing the entire place and its surrounding sandy land with a value
of $ 750000. The home making use of concrete and beam frame around it
and furthermore, you also have the main house, guest house beside the
lake, and area sufficient to land a helicopter.
The primary residence has two bedrooms, two bathrooms, and amusement
place is open, whereas his guest house in a smaller area because it has
only one bedroom and bathroom. The central house has a long and winding
road. Sights of the desert landscape are shown in the main house. The
desert may be seen right from the floor, ceiling, up to a dome-shaped
roof. However, the balcony provides a number of places to sunbathe.
Even though the sun shone vibrantly outside the home, in the high
temperature will not feel hot. The home will remain cooler because the
brick walls and floors made? Of ceramic material, which put together
with the corner of the window that is made to make a secure and safe
area? The home is constructed on a hill fractional active volcano with a

Morpheus Lunar Lander Try Finishes With Crash and Burn, Ultimate Explosion
Morpheus Lunar Lander Try Finishes With Crash and Burn, Ultimate Explosion
Morpheus Lunar Lander Try Finishes With Crash and Burn, Ultimate Explosion
Observed here after details took a turn for the serious (worst?), NASA's brand-new Morpheus Lander finishes its life on a test launch pad. Everything begin smooth enough (it goes up), however it collapses on its side and gets fire and worthwhile explosion at 1:52 and 2:12. Furthermore info so that you can impress a date and, I don’t know, perhaps scores a kiss: As streamed live by NASA, on 8/9/2012 at the Kennedy Space Center, the Project Morpheus lender tried its first free-flight test. Nevertheless shortly into the test a hardware component failure triggered the craft to flip over and crash and burn down in flames, followed by a number of explosions. Project Morpheus is a prototype "green" lander which is fairly affordable and more fuel efficient than earlier lander designs. Project Morpheus has cost $7 million over 2 .5 years, low-priced for a NASA project, due to "lean development" practices. Listen NASA, I am all for doing stuff inexpensively, but if your new, cheap lunar landers simply crash and blast they are like, not too good of a deal, you know? Think about you are at Best Buy and they are selling 55" flatscreens for $150. You get one, however when you get it home, it doesn't start up. Now how great of a deal was it? Food for thought or? Hit the jump for the unhappiness.

Edison’s Cradle? A Kinetic Toy Reinvented with Light
As part of his senior thesis exhibition at Musashino Art University
in Tokyo, art student Yasutoki Kariya re-imagined the ubiquitous desktop gadget,
Newton’s Cradle, employing a beautiful series of light bulbs. Named Asobi (which
reads roughly as “playing“) the 11-bulb installation produces a visual
interpretation of the well-known toy called after Sir Isaac Newton showing his
third law of motion regarding momentum: that for each action there is an equal
and opposite reaction. Although, rather than real energy created by the kinetic
force of steel balls, Kariya made an approach for making use of programmed
light and two surreptitiously placed pistons to set up this simply visual
experience that’s certainly a lot more hypnotic than the unique concept. .
As an added super bonus, the group over at the Experiments in Motion blog produced the animation above which very easily contends for just one of the most lovely animated gifs I have ever seen, now racking up over 167,000 shares on Tumblr this weekend. Asobi was selected for the 2012 Mitsubishi Junior Designer Award.
