Echolocation

Echolocation

Echolocation is how bats fly around in dark forests – they emit a sound, wait for the echo to return, and use that sound of the echo in each ear plus the return time to work out where an object is and how far away. Surprisingly (well, maybe not on this list!), humans are also capable of using echolocation. Use of echolocation is probably restricted to blind people because it takes a long time to master and heightened sensitivity to reflected sound.

To navigate via echolocation a person actively creates a noise (e.g. tapping a cane or clicking the tongue) and determines from the echoes where objects are located around them. People skilled at this can often tell where an object is, what size it is, and its density. Because humans cannot make or hear the higher pitched frequencies that bats and dolphins use they can only picture objects that are comparatively larger than those ‘seen’ by echolocating animals.

People with the ability to echolocate include James Holman, Daniel Kish, and Ben Underwood. Perhaps the most remarkable and well-documented of cases is the story of Ben Underwood, who lost both his eyes to retinal cancer at the age of three. He is shown in the video above (warning: the scene where he puts in his prosthetic eyeballs may be a bit disturbing for some).

Youngest Moms in the History

(age 5, Lida)

Linda Medina was the youngest girl ever to give birth. She was just 5 years, 7 months, and 21 days when her 2.7 kg (6.0 lb) son Gerardo was born. Linda got attendance of her parents when they noticed abnormal increase of her belly; she was thought to have had a tumor but when Linda was taken to hospital, there they get to know about her pregnancy. The mystery remains unsolved about the father of Gerardo. Both mother and son died at the age of 40 and 76 respectively.

(age 8, Lima)
The father of Gerardo was never discovered, but this girl was raped by two of her own cousins. She got pregnant and gave birth to a baby weighing 2 kg (4.4 lb) by cesarean section at a hospital in December 2006.

(age 9, Hilda Trujillo)
Hilda Trujillo was third youngest mother to give birth at the age of nine. In November Hilda entered the Maternity Hospital as the patient of Obstetrician Rolando Colareta, underwent examination by a team of 16 obstetricians, gland specialists, radiologists, psychiatrists and general practitioners. They reported her to be normal, only a little older-looking than other girls of her age. After one month, on December 1957 she gave birth to a baby girl. Her 22 year old cousin was arrested, accused of rape. Dr Rolando Colareta who examined her gave reasoning saying “the rape of minors is nothing so unusual here or anywhere else. But of course rape does not mean pregnancy in children so young, except in rare cases”.

(age 9, Phetchabun.Thailand)
Not that long ago in the month of February 2001 Wanwisa Janmuk became youngest Asian mother. World’s forth youngest mother was married to a 26 year old man; by the time of birth mother and father were nine and twenty seven year old respectively.

(age 9, Singapore)
After Thailand, Singapore was second Asian country where a nine year old girl gave birth to a baby. She was student of primary school, had an affair with 14 year old student. Both were alone at home in the absence of their parents and she ended up getting pregnant.

Trimethylaminuria

Trimethylaminuria

Thimethylaminuria is a rare metabolic disorder that causes the defect in a certain enzyme that breaks down trimethylamine, a compound released by protein-digesting bacteria, living in our stomach. Sufferers then begin to release the compound through their sweat, urine and other bodily fluids. The result? A lingering body odor reminiscent of rotten fish, thus earning the disease its more famous nickname ‘fish odor syndrome.’ The bad news? The disease is incurable. The good news? Aside from the odor, the disease has no other visible effect on the body (not counting the psychological effect the disease inflicts upon its victims), and the odor can be controlled by a low-protein diet that limits the intake of choline, an amino acid that can cause the odor to arise (although there has been cases where this didn’t have an effect on the symptom).

Interesting Fact: In the William Shakespeare play ‘The Tempest,’ one of its characters, Caliban, the socially rejected island dweller, exhibited symptoms of fish-odor syndrome, as evidenced by the following lines: “What have we here? A man or a fish? Dead or alive? He smells like a fish; a very ancient and fish-like smell …” which may suggest that the disorder was known at that time. In reality, the first recorded case of trimethylaminuria in medical literature happened in the 1970’s.

Survived Rabies Without Vaccination

Survived Rabies Without Vaccination

Jeanna Giese, of Fon du Lac, Wisconsin, defied medical odds by being the first person to survive rabies without a vaccination in 2004. The, then-15-year-old girl, got infected with the virus when she got bitten by a bat, but since the wound she sustained was shallow, she didn’t seek medical attention until thirty-seven days later, when the virus began attacking her body. The disease then progressed so fast that by the time she was admitted and diagnosed at the Children’s Hospital of Wisconsin in Milwaukee, she was in a near-state coma. But instead of giving up, Rodney Willoughby, an infectious disease specialist in the hospital, decided to try a novel treatment on Giese to save her life. The treatment involved giving her a cocktail of drugs that would induce a coma, to preserve her brain from the virus. This was to give Giese’s immune system time to fight the deadly disease, while giving her a chance to survive. The risky treatment worked, however, and thirty-one days later, she was declared rabies-free. Although the treatment left Giese with some brain damage, the girl responded to rehabilitation therapy and recovered quickly, much to the surprise of her doctors.

Interesting Fact: The experimental treatment that was used to cure Giese, dubbed the Milwaukee Protocol, is now currently under trial, and so far two patients out of twenty-five were cured. However, there had been some controversies regarding Giese’s survival under the treatment, one of which is that Giese was infected with a weaker form of rabies, and that significantly affected her response to the treatment.

Baby with a ‘Mask

Baby with a ‘Mask’

A 14-month old boy from Hunan, China, was born with a transverse facial cleft crossing his face from ear to ear, dividing his face into two parts, giving him the illusion that he’s wearing a mask. The cause for the defect of the baby (named Kangkang) is still undetermined, but an infection might be the culprit. Although the treatment to correct the cleft is terribly expensive, Kangkang’s family were, fortunately, able to come up with the 300-400,000 yen needed for the surgery. Pictured above is a much milder form of the same illness.

Interesting Fact: Facial clefts are, comparatively, rarer that cleft lips and palates, but they have similar origins: they are caused by the incomplete fusing of the facial bones of babies during conception.

Three Babies from Two Wombs

Three Babies from Two Wombs

Hannah Kersey of Northam, Devon, England, was born with uterus didelphys, a malformation of the reproductive organs that resulted in her having two wombs. In December 2006, Kersey defied odds of 25 million to one by giving birth to three healthy girls from her two wombs. Identical twins Ruby and Tilly were delivered from one womb, while Grace was delivered from the other. While simultaneous gestation of the two wombs in women with uterus didelphys can happen (70 cases were recorded), Kersey’s triplet birth was a medical first.

Interesting Fact: Women with uterus didelphys are often asymptomatic, meaning they aren’t aware of their condition until they are medically examined. In pregnancies of women with this condition, premature birth is quite common. In Kersey’s case, the triplets arrived seven weeks prematurely.

Liver Baby

Liver Baby

Ncise Cwayita, from South Africa, gave birth to a healthy 2.8 kilogram baby girl, despite the fact that she developed, not in her mother’s womb, but in her liver. The strange pregnancy was thought to be caused by the embryo falling out of the fallopian tube and attaching itself to her liver (this is called extrauterine pregnancy). Since the liver is a rich source of food for the embryo, it continued to gestate as normal, as it is protected by the placenta. Although babies developed out of the uterus often die within a few weeks, the baby girl, named Nhlahla (‘luck’ in Zulu) appears to be perfectly healthy.

Interesting Fact: There have been only fourteen documented cases of babies conceived in their mother’s liver. Of these cases, only four survived the pregnancy (including Nhlahla).

Lost Skin

Lost Skin

After taking a ten-day course of Bactrim, a very common antibiotic, to treat a sinus infection, Sarah Yeargain, from San Diego, California, was shocked when her skin suddenly started sloughing off her body. ‘I started to get some minor swelling and discoloration in my face and it progressed into blistering on lips and swelling on my eyes. It then progressed into blisters all over my face and chest and arms,’ Yeargain said. Two days later, at the San Diego Regional Burn Center at the University of California, she lost the skin on her entire body, including her internal organs and the membranes on her eyes, mouth and throat. Doctors gave her a slim chance of survival, but after covering her entire body with transcyte, an artificial skin replacement, and some medications to control the internal bleeding, Yeargain miraculously recovered. Within a week later, her skin grew back. It is thought that the cause of Yeargain’s dramatic skin loss is toxic epidermal necrolysis, which basically is a severe allergic reaction to the antibiotic she took.

Interesting Fact: Fans of the TV series ‘House, M.D.’ might recall the second-to-the-last episode of Season 5 (entitled ‘Under My Skin’), where a patient exhibited toxic epidermal necrolysis while under House and his medical team’s care.

Keys in Brain

Keys in Brain

In September 2008, 17-month old Nicholas Holderman, from Kentucky, made an astonishingly fast recovery after a freak accident where the toddler had a set of car keys impaled to his brain. The toddler was playing with his two older brothers when he somehow fell upon the keys. One of the keys pierced his eyelid and made it all the way to his brain. The parents Staci and Chris, alerted by his scream, went immediately to see what happened and were shocked by what they saw. The mother immediately called 911, and Nicholas was helicoptered to a medical unit. The medical team managed to remove the key successfully, without damage to the brain, and although the eye was ruptured, Nicholas’s eyesight was completely unaffected.

Interesting Fact: A quite similar but less severe incident occurred at a restaurant in Minnesota on July 2007, where an unnamed boy accidentally fell upon the fork he was holding. Fortunately, the fork only went through and out of his nose, and it was successfully removed with little damage to his face.

Head Reattached

On July 12, 2002, 18-year old Marcos Parra was involved in a car accident that left his skull literally separated from his cervical spine, in a condition called internal decapitation. Only the ligaments on his neck were connecting his head with his body, but his spinal cord and arteries were intact. However, a medical team led by Dr. Curtis Dickman (pictured above), a neurosurgeon at the St. Joseph’s Hospital in Phoenix, Arizona, saved his life by performing a radical, groundbreaking operation wherein two surgical screws were used to fasten Parra’s head to his spine. Amazingly, the risky operation worked, and Parra fully recovered. Since then, Dickman’s team has successfully performed the same surgery on two other patients.

Interesting Fact: There is a similar story to this. Ricky Barker was also internally decapitated after a 2004 accident where the bike he was riding collided with a car. Three months later however, Barker walked out of the hospital with only a paralyzed left arm, a limp and a hole in his throat (so that he could breathe) to remind him of the accident that almost took his life.

The girl who doesn’t age

Brooke Greenberg of Reisterstown, Maryland, has baffled the medical world because of her mysterious condition. Brooke, who just turned seventeen last January, still has the physical appearance and mental capacity of a toddler. She is just 30 inches (76 cm) tall and weighs around 16 pounds (7.3 kg) and her mental age is estimated to be about the same as a 9 to 12 month-old child. She also hasn’t learned to speak yet. Scientists, who have termed Brooke’s condition Syndrome X, believe that her abnormality is caused by a defect in the genes that control her body’s aging. “There’ve been very minimal changes in Brooke’s brain … Various parts of her body, rather than all being at the same stage, seem to be disconnected,” said Dr. Richard Walker of the University of South Florida College of Medicine, of Brooke’s aging process. However, scientists see Brooke’s condition as an opportunity for them to study the mysterious process of aging. Walker, who has already published a paper on Brooke’s disorder, said, “Our hypothesis is that she is suffering from damage in the gene or genes that coordinate the way the body develops and age. If we can use her DNA to find that mutant gene then we can test it in laboratory animals to see if we can switch if off and slow down the aging process at will. Just possibly it could give us an opportunity to answer the question of why we are mortal.”

Interesting Fact: When specialists began decoding Brooke’s DNA sequence, they found out that certain genes associated with DNA repair were normal. Mutated copies of those genes are thought to be responsible for ‘rapid aging’ disorders like progeria and Werner syndrome.

Antisa Khvichava - World Olest Women Celebrates 130th Birthday

Antisa Khvichava - World Olest Women Celebrates 130th Birthday

World Records Paavan S - Targetseo.com - SEO India | Saturday, July 10, 2010 |Guinness World Records 2010, world oldest, world oldest women | 0 comments »

The authorities in the republic of Georgia have announced that a woman called Antisa Khvichava from their country is the oldest person in the world now. The lady has celebrated her 130th birthday on July 8 at her home in a remote mountain village.

The 130 year old Antisa Khvichava, who claimed to be the oldest person, was born on 8th July 1880 in western Georgia. The oldest lady lives with her 40 year old grandson. In 1985, Antisa retired from her job as a tea and corn picker, at the age of 85 years.

According to Khvichava, she has always been healthy after working whole life both at home and at the farm. She can speak only in Mingrelian, which is their local language. She needs an interpreter to talk with the foreigners.

During a civil war, which collapsed the Russian Empire, Antisa lost her birth certificate. However, her age was confirmed to be 130 years by two Soviet documents.

Antisa Khvichava’s claim of being the oldest person will be examined by the Gerontology Research Group. If this is confirmed, she will replace Eugenie Blanchard of France, who is now officially the oldest person in the world at 114 years.

The same type of claim was made by the northern Kazakhstan officials last year. They claimed to possess documents to prove Sakhan Dosova of Karaganda to be the oldest person, who celebrated her 130th birthday on March 27, 2009. In addition, the provided an authentic passport to prove that she was actually born on 1879.

Oldest Women

Jeanne Louise Calment of Arles, France was the world's longest living person. Jeanne was born on February 21, 1875 and died on August 4, 1997. Her height was 4'11" (1.50m). Jeanne died at the age of 122 in a nursing home in Arles. She lived 122 years and 164 days (44,724 days total). Jeanne's name appears in the Guinness Book of World Records. At age 121, she released her two CDs, one in French and another in English titled, Maitresse du Temps (Time's Mistress). During the end stage, she became blind, she could not hear properly and was confined to a wheelchair but was in high spirits and mentally alert. Interesting fact is that Jeanne smoked cigarettes until the age of 117.

Worlds Tallest Man.

The world's tallest man ever recorded in the history of mankind - Robert Wadlow, was born in Alton, Illinois, in 1918, and was 6 feet tall by the time he was even eight years old. He suffered from the disorder Gigantism that makes the lower portions of the body extremely large, while the head and torso remain at normal sizes. This is caused by a pituitary gland tumor that excretes large amounts of growth hormone, resulting in the disorder that is technically called as acromegalic gigantism. He reached a final height of 8 feet 11 inches at the age of twenty-one years, and finally died of an inflamed leg.

The story of the 256 old year man

In our today world it is impossible for one to believe that a man can live up to the age of 150 years let alone 256 years. According to Time magazine and the New York Times that were published in the year 1933, there died a man whose age was 256 years. I am not sure if he was lucky to have lived up to this age or not.

He went by the name of Li Ching-Yun. In his lifetime he was able to bury 23 wives. He was able to get 180 descendants by the time of his death. If he were in Africa he would have been the role model of many men as the worth of a man was measured by the number of wives and children one had.
Li Ching-Yun claimed that the secret to his long life was sitting like a tortoise, sleeping like a dog, walking sprightly like a pigeon and keeping a quiet heart. He shared this information with a warlord that wanted to know what to do to live that long. Li insisted that peace of mind and calmness were the main contributors to his long life. For those that wonder what the man ate, you will be surprised to learn that he mainly consumed rice and wine.

Not much is known about the early life of Li Chung. The information that is known would be that he was born in the same town where he died. This would be in the province of Szechwan in China. He was literate by the age of ten and often traveled to Shansi, Tibet, Kansu and Manchuria to get herbs.

He continued selling herbs for almost 100 years. He sold his own herbs and also other peoples herbs. Time magazine also indicates that his fingernails were six inches long.

Many people by the age of 80 are usually shriveled and cannot do a lot of things for themselves. Surprisingly Li was very youthful and could do a lot for himself. This lead to many people doubting if he was that old.
Li admitted that he was born in the year 1736 and us this would make him only 197 years contrary to the supposed 256 years. It is a professor at the Minuko University that proved that Li was born in the year 1677. He was able to proof this by producing records that show that the Chinese government honored him on his 200th birthday.

This leads to the huge question if Li had forgotten his own age or was he even the legit Li. Looking at it from a medical perspective, it seems impossible for one to be able to live for that long. The age of Li has surpassed the official record by more than 130 years. It is claimed that he looked like a sixty year old.

The only reasonable conclusion would be that he either had a superhuman body or all this stories are mere exaggerations. Problem is we may never know the complete truth

Today almost everything runs on electricity. We use electricity to run trains, cook, lighting and so much more. Thus it is very important that people are able to know where they can get all the required electricity. People are able to tap energy from alternative sources of energy to help relieve the common sources of electricity.

Many companies are trying their best to try and cut down their electricity consumption. A good example would be Google. Google consumes a lot of energy. Google searches require the same energy that an 11 watt bulb requires when it's on for an hour. So one can be able to estimate how much energy is required for the Google servers and all other equipment to run. Thus Google has tried to cut their energy costs by developing advanced cooling methods and using energy saving techniques.

Others companies are also following the same trend. For example HP. It presented a paper to the 4th international conference on energy sustainability that describes how HP plans how they will use manure of cows to power their data centres. The title of the paper is design of Farm Waste-Driven supply Side Infrastructure for Data centers.

The manure that would be used will be from midsized dairy farms. Electricity will be derived form it by putting it through an anaerobic digester. The heat that is derived from this process would be used to power the turbines of the data centers cooling system. The electricity that is derived from this process will be used to power the data center. The temperature of the anaerobic digester would be regulated by the waste heat that is generated by the data center. This process ensures that there is maximum efficiency. This process also produces enough energy to be able to run the dairy farm. Thus one not only saves power use by the data centers but also the dairy farm.

According to HP, a dairy farm with about 10000 cows produces approximately 200000 tones of manure in a year. The manure produces methane gas. According to research this gas is more detrimental to the environment than carbon dioxide. The manure also pollutes the environment by polluting the rivers and streams. Thus HP using this manure to produce electricity will greatly improve the environment as it gets rid of this pollutant.

Other than reducing pollution, this process will also help boost the economy of the farms. The farms will be able to use this same electricity to run their farms and also earn huge chunks of money by selling the manure to be used elsewhere to produce the electricity. The farms can earn approximately two million dollars annually from selling the power that they produce.
