Bermuda Triangle: New anomalous phenomenon discovered

Thursday, June 21, 2012 Posted by Glenn 0 comments


Bermuda Triangle: New anomalous phenomenon discovered. 45395.jpeg
Recently, American scientists who studied the sea near the famous Bermuda Triangle have found another "anomaly". They saw that the surface waters in this area are literally teeming with a wide variety of viruses. However, the viruses do not represent any danger for humans as they only interested in oceanic bacteria.

The very phrase "Bermuda Triangle" has appeared only recently - it was coined by a fan of Spiritualism and esoteric Vincent Gaddis in 1964. By this toponym he meant an area located between the island of Puerto Rico, the Florida coast and Bermuda. According to the famous mystic of the last century, this area of the Atlantic became notorious due to the fact that hundreds of ships and aircraft disappeared there. Some ships, however, were found later, but without their crews and passengers.
All this made Gaddis suggests that there was some anomaly in this area. However, he was not the first one to express this idea. In 1950 an American journalist Alexander Jones wrote an article about the mysterious disappearance of ships in this region (which he called simply and tastefully - Sea Devil). Yet, the Bermuda Triangle acquired real popularity in 1974, when Charles Berlitz, a popularizer of science, published a book under the same title where he collected descriptions of various mysterious disappearances in the area. The book immediately became a bestseller, and as a result the mysterious and dangerous Sea Devil became known to the entire world. After that different groups of scientists engaged in searching for reasons to explain these disappearances.

However, over time the skeptics slowly gained the upper hand over amateur mystics. No anomalies in this part of the ocean were found, and the U.S. Coast Guard has issued several reports according to which the disappearance of ships in the Bermuda Triangle did not occur more frequently than in other regions of the ocean, and they occurred mainly due to storms. Historians, digging in the archives, found that the area since the discovery of America was very often visited by various vessels, including pirate ones. Until the second half of the 20th century sailors made no mention of it as a mysterious place where ships were constantly perishing. Persnickety journalists analyzed Berlitz's book and found that most of the facts presented by the writer were not entirely true, and some were just made up.
By the 1990s, the interest in the Bermuda Triangle was largely exhausted. Recently, however, scientists regained interest in this area, because they did discover one anomaly there. However, it has nothing to do with the disappearance of ships and aircraft.

A team of U.S. scientists led by Professor Craig Carlson of the Bermuda Institute of Oceanology (St. George, Bermuda) have been conducting oceanographic research in the northwestern part of the Sargasso Sea for ten years, near the Bermuda Triangle and Bermuda islands. Recently a report on the work of the biologists has been published. Especially interesting in this report was the fact that, according to the observations of scientists, most numerous living organisms in the surface layers of the ocean in this region are viruses.
Interestingly enough, the dynamics of these microscopic organisms is directly linked with the seasons. For example, in the summer viruses multiply actively in the water layers at depths ranging from 60 to 100 meters, and their number is up to ten million particles per drop of water. In the winter, sometimes they did not exist in the surface layers at all as they would go into the depths, following their masters.

The researchers analyzed the DNA of the viruses caught and found that 90 percent of them still were not known to science. However, these microorganisms, both known and unknown, did not present any danger to humans. They all belong to a group of bacteriophages, that is, the objects of their attacks are bacteria living in the ocean. Bacteriophages are known to be very old-fashioned and conservative as they do not change their habits, and do not attack other creatures. 
To be able to reproduce, bacteriophages lie in wait for unsuspecting bacteria. They attach themselves to their cell walls and enter into the victim's DNA. Furthermore, they integrate into the genome of the bacteria (which is a single circular DNA molecule, lying freely in the cytoplasm and not protected by any walls). This makes them forget about their own responsibilities and focus on producing all the necessary molecules for the assembly of new viruses. This assembly also takes place inside the bacterial cell. When the number of newborn bacteriophages reaches several million, they come from the host cell, effectively breaking it into pieces, and then go in search of new victims.
The organic molecules of the dead bacteria fill the water surrounding them, and since bacteriophages kill hundreds of thousands of cells, it is not surprising that the sea surface in this place turns into a nutrient broth. Other bacteria hurry there for a feed and quickly become prey of cunning virus. This means that the bacteriophages form a microscopic ecosystem where they live.
 
Other marine creatures, unicellular and multicellular planktonic organisms, also enjoy the fruits of their work. Some are attracted by free nutrient broth, and others - by the bacteria feeding on it. It turns out viruses create a "cafeteria" in the surface layers of the sea. Even whales and dolphins come to eat there (these, in turn, are interested in swarms of krill feeding on microplankton and fish eating krill).
Scientists were amazed by what they saw because they did not know about this role of viruses in the formation of oceanic ecosystems. According to many oceanographers, oceanic viruses are very poorly understood because they are hard to catch. But now it is clear that they are countless in all seas and oceans.

"While we cannot see them with the naked eye, viruses are the dominant form of life in the ocean. They constitute 95 percent of the total biomass of the ocean. That is, the mass of virus is even larger than the mass of krill, fish and larger animals such as whales, combined. Given the pace of virus multiplication and their number, it becomes apparent how important their role in nutrient cycling on the planet is," said one of the authors of the study of biological "anomalies" of the Bermuda Triangle Dr. Rachel Persons.
However, some experts believe that in this case there are no abnormalities specific to the Bermuda triangle as processes involving the viruses are occurring in many areas of the oceans. For example, biologists from the U.S. and Canada investigated the surface waters of the North Atlantic and reported that the most diverse viral community (129,000 genotypes) was found off the coast of British Columbia. The number of these microorganisms is also very high - approximately 50 million particles in a drop of water, which is five times greater than in the Bermuda Triangle. This "virus rage" is explained by the fact that this area has rising sea currents (upwelling), bringing nutrients from the depths of the ocean to the surface. In such areas sentient beings are more abundant and their diversity is higher than in the surrounding areas, and the virus is no exception to this rule.
It appears that the largest "virus carrier" on the planet is exactly in the oceans. It is fortunate that most of microscopic parasites living in it are not dangerous to humans.

Difference between crocodiles and alligators

Thursday, May 17, 2012 Posted by Glenn 1 comments


While they look similar to the untrained eye, crocodiles and alligators do have distinct differences. These two types of reptiles are found in different parts of the world, and have unique physical distinctions, including different shaped snouts. Both are part of the Crocodilia order, along with caimans and gharials, which also share a superficial resemblance.


Snout Differences


In terms of physical differences, observing the snout — the mouth and nose — is one of the simplest ways to distinguish between a crocodile and an alligator. Crocodiles have long, narrow, V-shaped snouts, while those of alligators are wider and U-shaped. These differences are indicative of the type of diet that each species favors. The wide snout of the alligator packs more crushing power, making it easier to secure prey such as turtles. By contrast, the narrow snout of the crocodile is suited for fish as well as small mammals.

Jaw Differences

The jaws found on a typical crocodile and an alligator are also different. The upper and lower jaws of the crocodile are essentially the same width, with the teeth exposed in an interlocking pattern. They also have a large, protruding fourth tooth on the lower jaw that is accommodated by depressions in the upper jaw just behind the nostrils. The alligator, however, has a wider upper jaw, allowing the lower teeth to fit into it snugly, effectively hiding them from view. Only the teeth of the upper jaw are exposed along the lower jaw line.

Color Differences

Alligators and crocodiles are also slightly different colors. The typical crocodile tends to have a coloration that is an olive brown hue. Alligators usually have a darker, almost black appearance.

Location and Habitat

Crocodiles and alligators are also found in different locations around the globe. Both crocodiles and alligators do well in environments that feature slow moving rivers with grasslands located adjacent to the river banks. Crocodiles live in parts of North, Central, and South America, and can be found in areas of Africa, Australia, and the southeast part of Asia. Alligators are native in the eastern section of China and the southern area of the United States, and are most common in states along the Gulf Coast. The lingual salt glands in crocodiles allows them to be more at home in salt water than alligators.

Branches of the Family Tree

In some circles, it is considered proper to refer to these families as being different branches of a common tree. There are 23 different species in the Crocodilia order found in the world today, and each is in one of three families. The Crocodylidae family includes all the species of crocodiles. The Alligatoridae family includes two subfamilies: Alligatorinae, or alligators, and Caimaninae, or caimans. Caimans resemble alligators and crocodiles, although most species are much smaller. The third family, Gavialidae, includes only one species: the gharial.

Caimans and Gharials

Similar in appearance to other members of the same order, both caimans and gharials are long, semi-aquatic reptiles with extended snouts. Caimans are in the same family as alligators, but most species are much smaller — often around 6.5 to 8 feet (2 to 2.5 meters) long compared to 13 feet (4 meters) for American alligators. These reptiles are found in Central and South America. The gharial, found only in India, has a much narrower snout than other species in this order.

Safety

Both crocodiles and alligators possess a great deal of strength and speed, and even on land, these reptiles are able to pursue and overtake prey with relative ease. People who have not been trained to deal with these animals should not make direct contact. In the event that a crocodile or an alligator has escaped from a zoo or wildlife sanctuary, or wandered from the wild into a populated area, anyone who sees it should leave the immediate area and report the sighting to the authorities.

Top 10 Freaky Animals

Tuesday, March 20, 2012 Posted by Glenn 0 comments

Article by kate from bukisa.com

Many people are familiar with the popular candy, Dum Dums. If you don't know, Dum Dums are a type of sucker with various flavors, one of which is the mystery flavor. What the mystery flavor actually is, is when the factory has a little bit of two different flavors left, and not enough of one to make a batch, they combine the 2, slap a question mark wrapper on it and call it a day. So one time the mystery may be strawberry banana, another time it may be pineapple cotton candy, you never know. Well, sometimes I wonder if something like that happened with the creation of animals. Sometimes it seems as if God didn't have enough to make parts for one species so he got a little creative.

Seapig

Here is a dum dum mystery flavor animal, not quite a pig, not quite a sea cucumber either. Also known as scotoplanes, these freaky animals live at the very bottom of deep oceans, usually at depths at least over 1000 meters. These little oddballs most often appear in large quantities at a times, sometimes as many as hundreds are observed. The sea pig is a type of deep sea cucumber, and this is very common behavior for such animals.

Giant Isopod

For many North Americans, this is a very unusual creature, but Giant Isopods are in fact very common but freaky animals in many areas of the world. They are extremely common in northern Taiwan, and are also abundant in cold deep waters within the Atlantic Ocean. They contain white mean quite similar to crab and lobster, and is very easily eaten.

Thorny Devil Lizard

The Thorny Devil Lizard comes to us from Western Australia, home to many freaky animals. They grow to be about 8 inches in length and can live up to 20 years.

Hagfish

There is much debate surrounding this freaky animal, not all scientists seem to agree on whether or not the Hagfish is in fact a fish.

Hairy Frog

This freaky animal comes from Central Africa, while it is technically on the conservation watch list, it is classified as “lowest concern”. Again, dum dum mystery flavor theory put to the test.

Human-Faced Carp

These fish reside in very remote locations. This particularly freaky animal resides in a pond in Chongju, which is near Seoul, South Korea, and also found in Slovenia, in caves around and under Lake Bohinj.

Proboscis Monkey

This freaky animal just makes you want to laugh, is sometimes called the Long-Nosed Monkey, for obvious reasons, but it’s official Indonesian name is Bakantan. However, the Indonesian nickname is “monyet belanda” meaning Dutch monkey. They call them this because hen the Dutch colonists were occupying the area, the natives believed all Dutch to have big noses and big bellies. These monkeys are considered endangered.

Goblin Shark

The Goblin Shark, or Mitsukurina Owstoni is found at depths where sunlight is not. They are found all throughout the world from Australia to the Gulf of Mexico, but their highest concentration appears to be near Japan. This freaky animal, while very rare, is not considered endangered and is classified as “least concern”

Wrinkle-Faced Bat

This bat is found all over Central America. The wrinkly freaky animal eats fruit but is not technically considered a “fruit bat”. It’s scientific name is derived from the word “senex”, which, quite unsurprisingly means “old people”.

Aye-Aye

If you have seen the smash hit movie “Madagascar”, then you are familiar with the Aye-Aye, a nocturnal lemur native to the island of, you guessed it, Madagascar. This particular freaky animal is currently classified as “near threatened”. There is a second species very similar to the Aye-Aye that has since become extinct.

Masturbation may INCREASE prostate cancer

Monday, November 21, 2011 Posted by Glenn 0 comments

-article from http://www.webmd.com

Jan. 27, 2009 -- Frequent masturbation in young men is linked to higher risk of early prostate cancer, but it lowers prostate cancer risk for men in their 50s, a study shows.

High levels of male sex hormones, or androgens, may increase a man's risk of prostate cancer. But different studies of this question, done in different ways, have reached different conclusions.

To look at the question in a new way, a team of researchers at England's University of Nottingham looked at whether men with more intense sex drives were at higher risk of prostate cancer.

Polyxeni Dimitropoulou, PhD; Rosalind Eeles, PhD, FRCP; and Kenneth R. Muir, PhD, obtained detailed sexual histories from 840 men. About half the men got prostate cancer by age 60, and about half did not have cancer.

The findings were surprising. Sexual intercourse did not affect prostate cancer risk. But frequent masturbation did -- in different ways, at different times of life.

"Frequent masturbation during men's 20s and 30s increased their risk of prostate cancer," Dimitropoulou tells WebMD. "But men in their 50s who masturbated frequently had decreased risk."

Of course, masturbation frequency is relative.

For men in their 20s, "frequent masturbation" was two to seven times per week. Compared to same-age men who reported masturbating less than once per month, 20-something frequent masturbators had a 79% higher risk of prostate cancer by age 60.

For men in their 50s, "frequent masturbation" was one or more times per week. Compared to same-age men who reported never masturbating, 50-something frequent masturbators had a 70% lower risk of prostate cancer.

What's going on? The study wasn't designed to answer that question. But Dimitropoulou and colleagues have some theories.

They suggest that young men genetically predisposed to have hormone-sensitive prostate cancer will be at higher risk if their bodies naturally produce high levels of male hormones -- the same hormones that give them an intense sex drive.

So it's not masturbation itself that's increasing prostate cancer risk in young men. More masturbation may just mean more sex drive -- and more androgens bathing prostate tissues.

That's not the case for older men. Dimitropoulou suggests that in older men, masturbation itself may actually be helpful, ridding the prostate gland of fluids that may contain cancer-causing substances.

"In mature age, it may be more important that toxins get flushed out of the system," she says. "And because the masturbation frequency was not as high in the men's 50s as it was in their 20s, even low levels of masturbation in the 50s has a protective effect."

These are just theories, Dimitropoulou warns. More research is needed to determine the exact role of sex hormones and sexual activity in prostate-cancer risk at different stages of life.

Meanwhile, Dimitropoulou, now at England's University of Cambridge, advises moderation for both younger and older men.

"It is kind of logical that a moderate level of masturbatory activity has to be maintained," she says. "Not too much, and not none at all."

Dimitropoulou and colleagues report their findings in the January issue of BJU International.

how to know if a girl is virgin or not

Sunday, November 20, 2011 Posted by Glenn 0 comments

One thing I learned from this article (www.articlesbase.com), we can't tell using our common sense whether if a girl is still a virgin or not! :)

Myth #1: A non-virgin walks with her legs wider apart.
Fact: How a girl walks is determined by her physical build - how wide her hip bones are or how fat her thighs are. It's also determined by her stride. This has nothing whatsoever to do with her virginity!

Myth #2: Hair between the eyebrows is gone after one loses her virginity.
Fact: This is one of the more bizarre stories. Hair between the eyebrows has nothing to do with virginity. If you happen to spot some hair between a girl's eyebrow which had never been there previously. it's simply because she has forgotten to pluck her eyebrows during the past few days!

Myth #3:A girls' fully-rounded backside suddenly flattens after she has sex.
Fact: If this were true, then there wouldn't be many of us walking around with nice, round, fully rear ends! It is impossible to lose tje elsaticity in your backside muscles simply through intercourse.

Myth #4: A virgin's breasts point upwards.
Fact: Virgins are just as likely to have sagging breasts!

Myth #5:One's breasts become larger after she loses her virginity. Fact: Just like a guy obtains his erection through a rush of blood to his penis, a gal's breasts could also swell when aroused. But this subsides. It is rude and childish to assume that those with ample chests are all non-virgins.

Myth #6: A virgin's urine is clear and sparkling.
Fact: Virginity cannot be confirmed with urine test; only pregnancy can. Besides, the quality of your urine is determined by your water intake - the more water you drink, the cleaner and clearer your urine will be.

Myth #7: A girl who has done it before has "a certain kind of look" on her face.
Fact: This is what many guys would say, and it is purely nonsense. Common sense tells you that there is no such thing as the virgin or non-virgin look!

Myth #8: A girl will definitely bleed when she has sex for the first time. If she doesn't, then she is lying about being a virgin.
Fact: One of the more reasonbale points brought up, this is perhaps the most common excuse for determining whether one is a virgin, but it is a misconception. Bleeding occurs when the hymen, a thin menbrane that covers the opening of a female's vagina, tears during intercourse. Thus, the general belief is that bleeding indicates loss of virginity. However, the hymen could also tear through physical activities like cycling and excessive exercises (like in the case of gymnasts). If tampons are not used corectly, they can also break the hymen. Also, some girls don't bleed after their first intercourse because they have more flexible hymens. Therefore, non-bleeding doesn't mean girls are non-virgins, either.

Sound Advice: Take these claims with a pinch of salt. These so-called facts are either traditional folktales or the output of someone's highly imaginative mind. In short, ignore all the outrageous things people say about how they can tell if a girl is a virgin. The truth is, no physical change will take place when a female (or male) loses their virginity. Only a medical check-up can confirm virginity by affirming the presence of an intact hymen. A thorough check-up can also tell whether the hymen has been torn by a penetrating penis or from falling from a bicycle. Other than that, the only way is to ask, and hope for an honest answer.
