Penguins, Cute Animals and Beautiful Photos



Penguins (order Sphenisciformes, family Spheniscidae) are a group of aquatic, flightless birds living almost exclusively in the southern hemisphere, especially in Antarctica. Highly adapted for life in the water, penguins have countershaded dark and white plumage, and their wings have become flippers. Most penguins feed on krill, fish, squid, and other forms of sealife caught while swimming underwater. They spend about half of their lives on land and half in the oceans.

Although all penguin species are native to the southern hemisphere, they are not found only in cold climates, such as Antarctica. In fact, only a few species of penguin live so far south. Several species are found in the temperate zone, and one species, the Galápagos Penguin, lives near the equator.

The largest living species is the Emperor Penguin (Aptenodytes forsteri): adults average about 1.1 m (3 ft 7 in) tall and weigh 35 kg (75 lb) or more. The smallest penguin species is the Little Blue Penguin (Eudyptula minor), also known as the Fairy Penguin, which stands around 40 cm tall (16 in) and weighs 1 kg (2.2 lb). Among extant penguins, larger penguins inhabit colder regions, while smaller penguins are generally found in temperate or even tropical climates (see also Bergmann's Rule). Some prehistoric species attained enormous sizes, becoming as tall or as heavy as an adult human. These were not restricted to Antarctic regions; on the contrary, subantarctic regions harboured high diversity, and at least one giant penguin occurred in a region not quite 2,000 km south of the equator 35 mya, in a climate decidedly warmer than today.

Waterspouts or Water Tornadoes



A waterspout is an intense columnar vortex (usually appearing as a funnel-shaped cloud) that occurs over a body of water and is connected to a cumuliform cloud. In the common form, it is a non-supercell tornado over water. While it is often weaker than most of its land counterparts, stronger versions spawned by mesocyclones do occur. Waterspouts do not suck up water; the water seen in the main funnel cloud is actually water droplets formed by condensation. While many waterspouts form in the tropics, locations at higher latitude within temperate zones also report waterspouts, such as Europe and the Great Lakes. Although rare, waterspouts have been observed in connection with lake-effect snow precipitation bands.
Waterspouts have a five-part life cycle: formation of a dark spot on the water surface, spiral pattern on the water surface, formation of a spray ring, development of the visible condensation funnel, and ultimately decay.




Non-tornadic
Waterspouts that are not associated with a rotating updraft of a supercell thunderstorm are known as "non-tornadic" or "fair-weather waterspouts", and are by far the most common type. Fair-weather waterspouts occur in coastal waters and are associated with dark, flat-bottomed, developing convective cumulus towers. Waterspouts of this type rapidly develop and dissipate, having life cycles shorter than 20 minutes. They usually rate no higher than EF0 on the Enhanced Fujita scale, generally exhibiting winds of less than 30 m/s (67 mi/h). They are most frequently seen in tropical and sub-tropical climates, with upwards of 400 per year observed in the Florida Keys. They typically move slowly, if at all, since the cloud they are attached to is horizontally static, being formed by vertical convective action instead of the subduction/adduction interaction between colliding fronts. Fair-weather waterspouts are very similar in both appearance and mechanics to landspouts, and largely behave as such if they move ashore.

Tornadic
"Tornadic waterspouts", also accurately referred to as "tornadoes over water", are formed from mesocyclonic action in a manner essentially identical to traditional land-based tornadoes in connection with severe thunderstorms, but simply occurring over water. A tornado which travels from land to a body of water would also be considered a tornadic waterspout. Since the vast majority of mesocyclonic thunderstorms occur in land-locked areas of the United States, true tornadic waterspouts are correspondingly rarer than their fair-weather counterparts. However, in some areas, such as the Adriatic, Aegean and Ionian seas, tornadic waterspouts can make up half of the total number.

Snowspout
A winter waterspout, also known as a snow devil, an icespout, an ice devil, a snonado, or a snowspout, is an extremely rare instance of a waterspout forming under the base of a snow squall. The term "winter waterspout" is used to differentiate between the common warm season waterspout and this rare winter season event. Very little is known about this phenomenon and only six known pictures of this event exist to date, four of which were taken in Ontario, Canada. There are a couple of critical criteria for the formation of a winter waterspout. Extremely cold temperatures need to be present over a body of warm water enough to produce fog resembling steam above the water's surface; this requires a 19°C (34°F) temperature difference between the water and the invading surface air mass. Like the more efficient lake-effect snow events, winds focusing down the axis of long lakes enhance wind convergence and likely enhance their development.





Waterspouts have long been recognized as serious marine hazards. Stronger waterspouts are usually quite dangerous, posing threats to ships, planes, helicopters, and swimmers. It is recommended to keep a considerable distance from these phenomena, and to always be on alert through weather reports. The United States National Weather Service will often issue special marine warnings when waterspouts are likely or have been sighted over coastal waters, or tornado warnings when waterspouts are expected to move onshore. When close to shorelines, waterspouts can devastate nearby coral reefs and marine organisms close to the surface.

Rainforest, What Is That?


Rainforests are forests characterized by high rainfall, with definitions based on a minimum normal annual rainfall of 1750-2000 mm (68-78 inches). The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests.
Around 40% to 75% of all biotic species are indigenous to the rainforests. It has been estimated that there may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests are also responsible for 28% of the world's oxygen turnover, sometimes misnamed oxygen production,processing it through photosynthesis from carbon dioxide and consuming it through respiration.
The undergrowth in a rainforest is restricted in many areas by the poor penetration of sunlight to ground level. This makes it easy to walk through undisturbed, mature rainforest. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs and small trees, called a jungle. There are two types of rainforest, tropical rainforest and temperate rainforest.


Many of the world's rainforests are associated with the location of the monsoon trough, also known as the intertropical convergence zone. Tropical rainforests are rainforests in the tropics, found in the equatorial zone (between the Tropic of Cancer and Tropic of Capricorn). Tropical rainforest is present in Southeast Asia (from Myanmar (Burma) to Philippines, Indonesia, Malaysia, Papua New Guinea and northeastern Australia), Sri Lanka, sub-Saharan Africa from Cameroon to the Congo (Congo Rainforest), South America (e.g. the Amazon Rainforest), Central America (e.g. Bosawás, southern Yucatán Peninsula-El Peten-Belize-Calakmul), and on many of the Pacific Islands (such as Hawaiiʻi). Tropical rainforests have been called the "Earth's lungs", although it is now known that rainforests contribute little net oxygen addition to the atmosphere through photosynthesis.



Temperate rainforests are rainforests in temperate regions. They occur in North America (in the Pacific Northwest, the British Columbia Coast and in the inland rainforest of the Rocky Mountain Trench east of Prince George), in Europe (parts of the British Isles such as the coastal areas of Ireland and Scotland, southern Norway, parts of the western Balkans along the Adriatic coast, as well as in the North West of Spain and coastal areas of the eastern Black Sea, including Georgia and coastal Turkey), in East Asia (in southern China, Taiwan, much of Japan and Korea, and on Sakhalin Island and the adjacent Russian Far East coast), in South America (southern Chile) and also in Australia and New Zealand.



Tropical and temperate rainforests have been subjected to heavy logging and agricultural clearance throughout the 20th century and the area covered by rainforests around the world is shrinking. Biologists have estimated that large numbers of species are being driven to extinction (possibly more than 50,000 a year; at that rate, says E. O. Wilson of Harvard University, a quarter or more of all species on Earth could be exterminated within 50 years) due to the removal of habitat with destruction of the rainforests.
Another factor causing the loss of rainforest is expanding urban areas. Littoral rainforest growing along coastal areas of eastern Australia is now rare due to ribbon development to accommodate the demand for seachange lifestyles.












The forests are being destroyed at a rapid pace. Almost 90% of West Africa's rainforest has been destroyed. Since the arrival of humans 2000 years ago, Madagascar has lost two thirds of its original rainforest. At present rates, tropical rainforests in Indonesia would be logged out in 10 years and Papua New Guinea in 13 to 16 years.
Several countries, notably Brazil, have declared their deforestation a national emergency. Amazon deforestation jumped by 69% in 2008 compared to 2007's twelve months, according to official government data.Deforestation could wipe out or severely damage nearly 60% of the Amazon Rainforest by 2030, says a new report from WWF.
However, a January 30, 2009 New York Times article stated, "By one estimate, for every acre of rain forest cut down each year, more than 50 acres of new forest are growing in the tropics..." The new forest includes secondary forest on former farmland and so-called degraded forest.

Fig Tree



In the Book of Genesis in the Bible, Adam and Eve clad themselves with fig leaves (Genesis 3:7) after eating the "forbidden fruit" from the Tree of Knowledge of Good and Evil. Likewise, fig leaves, or depictions of fig leaves, have long been used to cover the genitals of nude figures in painting and sculpture. Art collectors and exhibitors often added these depictions long after the original work was completed. The use of the fig leaf as a protector of modesty or shield of some kind has entered the language.




Also in the Bible (Matthew 21:18-22 and Mark 11:12-14, 19-21) is a story of Jesus finding a fig tree when he was hungry; the tree only had leaves on it, but no fruit. Jesus, then, curses the fig tree, which withers.
The biblical quote "each man under his own vine and fig tree" (1 Kings 4:25) has been used to denote peace and prosperity. It was commonly quoted to refer to the life that would be led by settlers in the American West, and was used by Theodor Herzl in his depiction of the future Jewish Homeland: "We are a commonwealth. In form it is new, but in purpose very ancient. Our aim is mentioned in the First Book of Kings: 'Judah and Israel shall dwell securely, each man under his own vine and fig tree, from Dan to Beersheba".
Buddha achieved enlightenment under the bodhi tree, a large and old sacred fig tree (Ficus religiosa).





Sura 95 of the Qur'an is named al-Tīn (Arabic for "The Fig"), as it opens with the oath "By the fig and the olive." The fruit is also mentioned elsewhere in the Qur'an. Within the Hadith, Sahih al-Bukhari records Muhammad stating: "If I had to mention a fruit that descended from paradise, I would say this is it because the paradisiacal fruits do not have pits...eat from these fruits for they prevent hemorrhoids, prevent piles and help gout."

In Greek mythology, the god Apollo sends a crow to collect water from a stream for him. The crow sees a fig tree and waits for the figs to ripen, tempted by the fruit. He knows that he is late and that his tardiness will be punished, so he gets a snake from the stream and collects the water. He presents Apollo with the water and uses the snake as an excuse. Apollo sees through the crow's lie and throws the crow, goblet, and snake into the sky where they form the constellations Hydra, Crater, and Corvus.
In Aristophanes' Lysistrata one of the women boasts about the "curriculum" of initiation rites she went through to become an adult woman (Lys. 641–7). As her final accomplishment before marriage, when she was already a fair girl, she bore the basket as a kanephoros, wearing a necklace of dried figs.
In the course of his campaign to persuade the Roman Republic to pursue a third Punic War, Cato the Elder produced before the Senate a handful of fresh figs, said to be from Carthage. This showed its proximity to Rome (and hence the threat), and also accused the Senate of weakness and effeminacy: figs were associated with femininity, owing to the appearance of the inside of the fruit. 




The word "sycophant" comes from the Greek word sykophantes, meaning"one who shows the fig". "Showing the fig" was a vulgar gesture made with the hand.
The fig tree is sacred to Dionysus Sukites (Συκίτης). The Indian fig tree, Ficus bengalensis, is the National Tree of India.
Since the flower is invisible, there are various idioms related to it in languages around the world. In a Bengali idiom as used in tumi jeno dumurer phool hoe gele, i.e., you have become (invisible like) the dumur flower. The derisive English idiom I don't care a fig probably originates from the abundance of this fruit. There is a Hindi idiom related to flower of fig tree, (Gular ka phool i.e. flower of fig) means something that just would not ever see i.e. rare of the rarest In Awadh region of Uttar Pradesh state of India apart from standard Hindi idiom a variant is also used; in the region it is assumed that if some thing or work or job contains (or is contaminated by) flower of fig it will not get finished e.g. this work contains fig flower i.e. it is not getting completed by any means.
Gular ka phool (flower of fig) is a collection of poetry in written in Hindi by Rajiv Kumar Trigarti.

There is also an old phrase in telugu Telugu which says 'Medi pandu chuda melimayyi undunu, potta vippi chuda purugulundunu', It means - 'The fig fruit looks harmless but once you open you find tiny insects [refers to the fig wasp] in there'. The phrase is synonymous to an english phrase - 'Don't judge a book by its cover'.




The Common Fig is widely known for its edible fruit throughout its natural range in the Mediterranean and Middle Eastern region, Iran, Turkey, Pakistan, northern India, and also in other areas of the world with a similar climate, including Arkansas, Louisiana, California, Georgia, Oregon, Texas, South Carolina, and Washington in the United States, south-western British Columbia in Canada, Durango, Nuevo León and Coahuila in northeastern Mexico, as well as areas of Argentina, Australia, Chile, Peru, and South Africa.
Two crops of figs are potentially produced each year. The first or breva crop develops in the spring on last year's shoot growth. In contrast, the main fig crop develops on the current year's shoot growth and ripens in the late summer or fall. The main crop is generally superior in both quantity and quality than the breva crop. However, some cultivars produce good breva crops (e.g., Black Mission, Croisic, and Ventura).
There are basically three varieties of common figs:
Caducous (or Smyrna) figs require pollination by the fig wasp and caprifigs to develop crops. Some cultivars are Calimyrna, Marabout, and Zidi.
Persistent (or Common) figs do not need pollination; fruit develop through parthenocarpic means. This is the variety of fig most commonly grown by home gardeners. Adriatic, Black Mission, Brown Turkey, Brunswick, and Celeste are some representative cultivars.
Intermediate (or San Pedro) figs do not need pollination to set the breva crop, but do need pollination, at least in some regions, for the main crop. Examples are Lampeira, King, and San Pedro.





Figs plants are easy to propagate through several methods. Propagation using seeds is not the preferred method since vegetative methods exist that are quicker and more reliable, that is, they do not yield the inedible caprifigs. However, those desiring to can plant seeds of dried figs with moist sphagnum moss or other media in a zip lock bag and expect germination in a few weeks to several months. The tiny plants can be transplanted out little by little once the leaves open, and despite the tiny initial size can grow to 1 foot (30 cm) or more one year from planting seeds.
For propagation in the mid-summer months, air layer new growth in August (mid-summer) or insert hardened off 15–25 cm (6-10 inches) shoots into moist perlite or a sandy soil mix, keeping the cuttings shaded until new growth begins; then gradually move them into full sun. An alternative propagation method is bending over a taller branch, scratching the bark to reveal the green inner bark, then pinning the scratched area tightly to the ground. Within a few weeks, roots will develop and the branch can be clipped from the mother plant and transplanted where desired.
For spring propagation, before the tree starts growth, cut 15–25 cm (6-10 inches) shoots that have healthy buds at their ends, and set into a moist perlite and/or sandy soil mix located in the shade. Once the cuttings start to produce leaves, bury them up to the bottom leaf to give the plant a good start in the desired location.




Figs can also be found in continental climate with hot summer, as far north as Hungary and Moravia, and can be harvested up to four times per year. Thousands of cultivars, most named, have been developed or come into existence as human migration brought the fig to many places outside its natural range. It has been an important food crop for thousands of years, and was also thought to be highly beneficial in the diet.
The edible fig is one of the first plants that was cultivated by humans. Nine subfossil figs of a parthenocarpic type dating to about 9400–9200 BC were found in the early Neolithic village Gilgal I (in the Jordan Valley, 13 km north of Jericho). The find predates the domestication of wheat, barley, and legumes, and may thus be the first known instance of agriculture. It is proposed that they may have been planted and cultivated intentionally, one thousand years before the next crops were domesticated (wheat and rye).
Figs were also a common food source for the Romans. Cato the Elder, in his De Agri Cultura, lists several strains of figs grown at the time he wrote his handbook: the Mariscan, African, Herculanean, Saguntine, and the black Tellanian (De agri cultura, ch. 8). The fruits were used, among other things, to fatten geese for the production of a precursor of foie gras.
Figs can be eaten fresh or dried, and used in jam-making. Most commercial production is in dried or otherwise processed forms, since the ripe fruit does not transport well, and once picked does not keep well.

Sun Bursts



Sun bursts are sudden releases of energy from the sun's atmosphere, known as the corona. Although the bursts are not visible to the naked eye, they represent tremendous amounts of power, and they can have an impact on Earth and more distant planets as the energy travels through the solar system. During periods of increased solar activity, sun bursts can become severe enough to disable satellites and other equipment, as humans have learned to their chagrin.

Changes in the sun's level of activity are caused by the sun's rotation. Like other bodies in space, the sun moves, and as it does, it creates a solar cycle which is caused by rotational forces along the surface of the sun. Sun bursts typically start with sunspots, dark areas which appear on the sun when the cooler inner core of the sun is temporarily exposed by the shifting corona. When sunspots start to spread, it can signal an expected increase in solar activity.

Solar flares, another type of sun burst, occur when the corona releases huge amounts of energy in the fraction of a second, causing a bright spot to appear. Solar flares often occur around sunspots, although they also occur inside the corona, where they cannot be confirmed with visual observations. A big solar flare can release enough energy to interfere with communications on Earth, as the electromagnetic energy from the sun interacts with Earth-bound communications systems and satellites.

In a radical form of sun burst called a coronal mass ejection (CME), the sun pushes out huge flares of plasma. These plasma flares can push against the Earth's atmosphere, causing especially bright, prolonged, and brilliant auroras, and they also increase radiation levels in space substantially. CMEs are one of the reasons that space travel is potentially very dangerous, as the increased radiation level could pose a risk to living organisms in spacecraft.

Scientists can use the ebb and flow of sun bursts to track the sun's cycles, and to gather more information about how the sun works. The activities observed in the sun are also known to occur in other stars, even though researchers cannot usually see them in action because of the great distances involved. Understanding patterns of sun bursts is important to the business community as well as the scientific community, because sun bursts can interrupt satellite launches, the flight of spacecraft, and many other human activities, sometimes with devastating effects.

Surgeon And 21-week Old Fetus Shaking Hands


This picture of a 21-week fetus hand reaching up through an incision in its mother's uterus to grab the finger of the surgeon who had just performed a life-saving procedure appeared in the November 16 edition of The National Enquirer.
It should be "The Picture of the Year," or perhaps, "The Picture of the Decade."

The 21-week-old unborn baby is named Samuel Alexander Armas, and is being operated on by a surgeon named Joseph Bruner. The baby was diagnosed with spina bifida and would not survive if removed from the mother's womb.

Little Samuel's mother, Julie Armas, is an obstetrics nurse in Atlanta. She knew of Dr. Bruner's remarkable surgical procedure. Practicing at Vanderbilt University Medical Center in Nashville, he performs these special operations while the baby is still in the womb. In the procedure, a C-section removes the uterus and the doctor makes a small incision to operate on the baby.

During the surgery on little Samuel, the little guy reached his tiny, but fully developed, hand through the incision and firmly grasped the surgeon's finger. The photograph captures this amazing event with perfect clarity.

The editors titled the picture, "Hand of Hope."

The text explaining the picture begins, "The tiny hand of 21-week-old foetus Samuel Alexander Armas emerges from the mother's uterus to grasp the finger of Dr. Joseph Bruner as if thanking the doctor for the gift of life."

That picture should be shown on every television newscast and run in every newspaper in America. It is a graphic reminder that growing in the womb of his or her mother is a baby. It is not a "glob of tissue," or "product of conception." That pre-born baby is a human being with all the emotions, will and personality of any human being. That picture says it in a way that a thousand words cannot.

Little Samuel's mother said they "wept for days" when they saw the picture. She said, "The photo reminds us my pregnancy isn't about disability or illness, it's about a little person." That's what it's always been about. That's what the liberal elite have tried to get us to forget. May this image jog our memories so that we will never forget.

Here is this amazing moment from different angle.

Mount Everest, The Highest Mountain In The World




Mount Everest (Tibetan: Chomolungma or Qomolangma, "Holy Mother") is the world's highest mountain, with a peak at 8,848 metres (29,029 ft) above sea level. It is located in the Mahalangur section of the Himalayas on the Nepal side of Nepal-China (Tibet) border. Its massif includes neighboring peaks Lhotse (8516 m), Nuptse (7855 m) and Changtse (7580 m).
In 1856, the Great Trigonometric Survey of British India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). In 1865, Everest was given its official English name by the Royal Geographical Society upon a recommendation by Andrew Waugh, the British Surveyor General of India. Waugh named the mountain after his predecessor in the post, Sir George Everest. Although Tibetans had called Everest "Chomolungma" for centuries, Waugh was unaware of this because Nepal and Tibet were closed to foreigners.




The highest mountain in the world attracts many well-experienced mountaineers as well as novice climbers willing to hire professional guides. While not posing substantial technical climbing challenges on the standard route (other eight-thousanders such as K2 or Nanga Parbat are much more difficult), Everest presents dangers such as altitude sickness, weather and wind.



By the end of the 2010 climbing season, there had been 5,104 ascents to the summit by about 3,142 individuals. Climbers are a significant source of tourist revenue for Nepal, whose government also requires all prospective climbers to obtain an expensive permit, costing up to US$25,000 per person. By the end of 2010 Everest had claimed 219 lives, including eight who perished during a 1996 storm high on the mountain. Conditions are so difficult in the death zone—altitudes higher than 8,000 metres (26,000 ft)—that most corpses have been left where they fell. Some of them are visible from standard climbing routes.


 Climbing Mount Everest is an expensive undertaking. Just the climbing gear required to reach the summit may cost in excess of US$8,000. Most climbers use bottled oxygen, which adds around $3,000 to the cost. The permit to enter the Everest area from the south via Nepal costs $10,000 to $25,000 per person, depending on the size of the team. The ascent typically starts in one of the two base camps near the mountain, both of which are approximately 100 km from Kathmandu and 300 km from Lhasa (the two nearest cities with major airports); transferring one's equipment from the airport to the base camp may add as much as $2,000.


 Beyond this point, costs may vary widely. It is technically possible to reach the summit with minimal additional expenses, and there are 'budget' travel agencies which offer logistical support for such trips. However, this is considered difficult and dangerous (as illustrated by the case of David Sharp). Many climbers hire "full service" guide companies, which provide a wide spectrum of services, including acquisition of permits, transportation to/from base camp, food, tents, medical assistance while on the mountain, an experienced mountaineer guide, and even personal porters to carry one's backpack and cook one's meals. The cost of such a guide service may range from $40,000 to $80,000 per person. Since most equipment is moved by sherpas, clients of full-service guide companies can often keep their backpack weights under 10 kg, or hire a sherpa to carry their gear for them. This can be contrasted with expeditions to less commercialized peaks (for example, climbers attempting Mount McKinley are often expected to carry 30+ kg backpacks and occasionally to tow a sled with 35 kg of gear and food.

The degree of commercialization of Mount Everest is a frequent subject of criticism. Jamling Tenzing Norgay, the son of Tenzing Norgay, said in a 2003 interview that his late father would have been shocked to discover that rich thrill-seekers with no climbing experience were now routinely reaching the summit.

Penguin Island In Western Australia









Penguin Island is a 12.5 ha island off the coast near Perth Western Australia, 700 m from Rockingham. It is home to a colony of Little Penguins, the largest population of the birds in Western Australia. The waters surrounding the island make up the Shoalwater Islands Marine Park.

Regular ferries carry tourists to and from the island and other marine-park sights. Access is also available by private boat or by swimming. Walking across a tidal sandbar at low tide looks tempting but is very hazardous—unpredictable tide rises have resulted in several drownings. Visitors should take their own supply of food and drink, since none can be purchased on Penguin Island, though there is a picnic area with seating. Waterless composting toilets are in use there.

Visitors are strictly prohibited from being on the island except during specified daylight hours from mid-September to early June. This means that only a small population of captive penguins can be viewed. However, there are many other sights including nesting seabirds and a 500-strong colony of pelicans.
Penguin Island has many geographical features, such as cliffs, small sea caves, headlands, beaches, coves, notches and natural bridges. There are also numerous wave-cut platforms.
Significant areas of Penguin Island include North Rock, Pelican Bluff, North Beach, McKenzies Well, South Beach, Abalone Point, and Surfers Beach.

There are numerous lookouts and walkways throughout most of the island. Some areas are fenced off to the public to protect wildlife and lessen dune erosion.
