Chudnite Mostove (The magnificent
Bridges) a rock phenomenon situated near the Zabardo village West Rhodope
mountain,Bulgaria. The "bridges" were shaped by the destructive
activity of the once high-water river. It transformed the marble clefts into a
deep water cave, the ceiling of which whittled up through time and collapsed,
allegedly during an earthquake. Geologists presume that the water carried the
debris away. As a result, the two left over bridge-shaped boulders remained. The
adjacent area is timbered by century-old conifers, largely spruces. In the past
the bridges had been one entire cave, formed under the erosive activity of the
river waters. Parts of it were collapsing with time, forming majestic marble
bridges. The huge bridge is about fifteen meters wide in its wider parts and
almost hundred meters long. It consists of three arches, as the largest one is
45 meters high and 40 meters wide. The small bridge is at a distance of 200
meters from the large one along the river current. It is blocked, 60 meters
long, with total height of 50 meters, and the height of the arch is 30 meters.
There is also a really small third bridge after it, which is a ponor cave, in
which the waters of Erkyupriya River disappear, to become visible again on the
surface 3 kilometers farther.

THE ASIDUS "MOON MELON" IS A FRUIT WE ALL WANT
"That is a Moonmelon, scientifically called as
asidus. This lovely fruit grows in some parts of Japan, and it’s recognized for
its strange blue color what you most likely don’t know about this fruit, is
that it can switch flavors after you eat it, everything sour will taste sweet,
and the whole thing salty will taste bitter and it gives water a strong orange-like
taste, this fruit is very expensive and easily called lavish fruit, and it
coasts about ¥16000
JPY (which is about 200 dollars)"
Ant Snapped in a tiny sphere of water
Trapped in a small just right
sphere of water, this inauspicious ant is unable to escape. A sudden downpour
gave it no time to take cover, and photographer Adam Gormley was there to depict
the image. Adam, from Noosaville, Queensland, Australia, had been photographing
spiders in his neighbor’s garden when the rain came down. He had no thought
there was an ant in one of the three millimeter droplets until he watched the
images later. Adam said: I was thinking it some dirt inside the drop, and it
was not my main focal point, I really liked the way the drop was sitting on the
aloe-vera leaf, with the tiny hairs. When I uploaded the image to my PC with
large view, and I think I shouted out loud in pleasure when I realized what I'd
captured by accident!

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.
