woman got herself sterilised to 'save the planet'

Toni Vernelli, 27, got herself sterilized because she wanted to save the planet!

At the age of 27 this young woman at the height of her reproductive years was sterilised to "protect the planet".

Incredibly, instead of mourning the loss of a family that never was, her boyfriend (now husband) presented her with a congratulations card.

While some might think it strange to celebrate the reversal of nature and denial of motherhood, Toni relishes her decision with an almost religious zeal.

"Having children is selfish. It’s all about maintaining your genetic line at the expense of the planet," says Toni, 35.

"Every person who is born uses more food, more water, more land, more fossil fuels, more trees and produces more rubbish, more pollution, more greenhouse gases, and adds to the problem of over-population."

While most parents view their children as the ultimate miracle of nature, Toni seems to see them as a sinister threat to the future.

sea organ

In 2005, architect Nikola Basic created the musical Sea Organ on the shores of Zadar, Croatia. It is the world's first musical pipe organ that is played by the sea. Simple and elegant steps, carved in white stone, were built on the quayside.

Underneath, there are 35 musically tuned tubes with whistle openings on the sidewalk. The movement of the sea pushes air through, and – depending on the size and velocity of the wave – musical chords are played. The waves create random harmonic sounds.

caged monkey

National Geographic has just chosen the winners of its International Photography Contest. Out of 148,203 images submitted, this particular one above by Chinese photographer Li Feng won for the category Animal - International.

Caged monkeys await their fate at a medical laboratory in Hubei Province, China. The judges liked that this image subverted the usual “romanticized” approach to wildlife photography, and more accurately reflected the fate of many of the world’s animals. The sneaker at the top provides scale and injects humanity into the scene; the anonymity of its wearer suggests concealment and complicity. The structure of the cages, the horror of the captivity, the crowded composition, and the claustrophobic tension all add up to a very sad and compelling photo.

9 ways to eat gold

Gold is often used as decoration and to add a bit of opulence to a luxurious meal. Often a fresh sprig of parsley cannot compare to the shine of gold. Beyond appearances many people believe that gold, if ingested, offers a wide array of health benefits. Today, fine dining chefs everywhere add gold to their signature dishes to add a lavish element. While gold is actually tasteless, it does impress and allows restaurants and manufacturers to charge exorbitant amounts of money for routinely mundane products.

tay zonday is back : cherry chocolate rain

Tay “I move away from the mic to breathe in” Zonday is back with a Dr. Pepper corporate-sponsored updated version of Chocolate Rain and a new professional YouTube video. Yay for Tay.

chocolate rain by tay zonday

Tay Zonday is a graduate student from Minneapolis, Minnesota. His YouTube song and video, "Chocolate Rain," is a little odd, but strangely appealing, and became very popular very quickly in the Summer of 2007. This led to appearances on VH1's Best Week Ever show and the Jimmy Kimmel Live show. The song's not bad, and the lyrics are cool, but it's the strangeness factor (his head movements, his short body and low voice) that makes this viral video click.

ten lb hairball removed from woman

An 18-year old woman went to the doctor for abdominal pain and a 40-pound weight loss. When the doctor performed a CT scan, they found a mass which turned out to be a 10-pound hairball!

Doctors found a mass there, and when they used a small camera, found that the hairball was taking up nearly her entire stomach.

The patient said that she has a habit of eating her own hair, a condition called trichophagia.

Doctors tried to use small incisions to remove the mass, but then had to go to traditional surgery to make sure the entire hairball was removed.

master of the killer ants

Illustration: Henri-Pierre Aberlenc

The Mofu people of northern Cameroon, Africa, have developed a unique process of defending themselves and their crops against termites and other pests: by calling on killer ants they called the jaglavak (Dorylus) for help!

The Mofu who sees his compound invaded by termites and ants calls on the jaglavak for help. Dorylus colonies are not easy to find. After identifying the nest or colony of jaglavak on the move, the Mofu removes from the colony several hundred to a thousand, or even more, Dorylus soldiers. […]

The Mofu put the jaglavak on the ground within an ocher circle from which extends a path, also traced in ocher, that leads toward the area of the most badly infested house. The Mofu admit that they do not see the jaglavak operate, but they claim that two or three weeks later, the harmful insects have disappeared, and the jaglavak as well, for they do not remain in the compound …

thousand year old riddle for all you dirty minded people....

The Exeter Book, a tenth century codex of Anglo-Saxon poetry is the largest collection of Old English literature. In addition to poems, there are about a hundred or so riddles (and yes, some of them are quite ribald!)

See if you can guess the answer to this 1,000-year old riddle:

Swings by his thigh / a thing most magical!
Below the belt / beneath the folds
Of his clothes it hangs / a hole in its front end,
stiff-set and stout / it swivels about.

Levelling the head / of this hanging tool,
its wielder hoists his hem / above his knee;
it is his will to fill / a well-known hole
that it fits fully / when at full length

He’s oft filled it before. / Now he fills it again.

the man with five kidneys

One day, Brigham Nordstrom of Hautapu, New Zealand got a kidney infection and was admitted to the hospital. There, doctors found out that he’s got a little something extra:

"The doctors took a scan. Then I had to get a second one done. They wanted to have another look."

Doctors had found one duplex kidney and one triplex kidney. Instead of having one tube or ureter joining each kidney to the bladder, Mr Nordstrom had two tubes on the left and three on the right.

Accordingly, the duplex kidney has two parts and the triplex has three parts, meaning it is quite likely Mr Nordstrom has five kidneys altogether.

why do worms go onto the sidewalk when it rains?

Most people assume that earthworms come to the surface during heavy rains to avoid drowning in their tunnels. In fact, worms can live totally submerged in water, so drowning isn’t the problem. But the rainwater that filters down through the ground contains very little oxygen, so the real reason earthworms come to the surface is to breathe.

Once above ground, earthworms are very sensitive to light, and even a brief exposure to the sun’s rays can paralyze them. Unable to crawl back into their burrows, they eventually dry out and die on the sidewalk.

idaho's fire rainbow

The atmospheric phenomenon known as a circumhorizon(tal) arc, or "Fire rainbow", appears when the sun is high in the sky (i.e., higher than 58° above the horizon), and its light passes through diaphanous, high-altitude cirrus clouds made up of hexagonal plate crystals. Sunlight entering the crystals' vertical side faces and leaving through their bottom faces is refracted (as through a prism) and separated into an array of visible colors. When the plate crystals in cirrus clouds are aligned optimally (i.e., with their faces parallel to the ground), the resulting display is a brilliant spectrum of colors reminiscent of a rainbow. The example shown above was captured on camera as it hung for about an hour across a several-hundred square mile area of sky above northern Idaho (near the Washington border) on 3 June 2006.

wanna see a life-size whale?


to blog or not to blog


Juan Enriquez offers a glimpse of some ground-breaking research to explore the potential of bioenergy. Our current energy sources -- coal, oil, gas -- are ultimately derived from ancient plants -- they're "concentrated sunlight." He asks, Can we learn from that process and accelerate it? Can we get to the point where we grow our own energy as efficiently as we grow wheat? (Less than a month after this talk, his company announced a process to do just that.)

Why Don’t We Have a Word for That?

Americans excel at inventing colorful expressions and slang, but it turns out other countries are pretty good at it, too. Here are a list of useful words from around the world that should’ve been invented for the English language:

Kummerspeck (Germany): "Grief bacon" - the weight that you gain by overeating when you’re worried about something.

Attaccabottoni (Italy): A "buttonholer" - someone who corners casual acquaintances or even complete strangers for the purpose of telling them their miserable life stories.

Modré Pondeli (Czech): "Blue Monday" - When you skip coming in to work to give yourself a three-day weekend.

Razbliuto (Russia): The feeling you have for a person you used to love, but don’t anymore.

Shitta (Iran): Leftover dinner that’s eaten for breakfast.

Tartle (Scotland): To momentarily forget the name of the person you’re talking to. The word helps reduce the social embarrassment of such situations: "I’m sorry, I tartled there for a moment."

Pana po’o (Hawaii): To scratch your head in an attempt to remember something you’ve forgotten.

Ngaobera (Easter Island): A sore throat caused by too much screaming.

Backpfeifengesicht (Germany): A face that’s just begging for somebody to put their fist in it.

Papierkrieg (Germany): "Paper war" - bureaucratic paperwork whose only purpose is to block you from getting the refund, insurance payment, or other benefit that you have coming.

Rujuk (Indonesia): To remarry your ex-wife.

Mokita (New Guinea): The truth that everyone knows, but no one will speak about.

Gorrero (Spain, Central America): Someone who never picks up the check.

Fucha (Poland): Using your employer’s time and resources for your own purposes. (Uncle John had never heard of such a thing and wanted to ask around the office if anyone else had, but everyone is still out to lunch.)

was the first controlled experiment actually in the bible?

One of the first - if not the very first - controlled experiments was actually described in the Bible. In the Book of Daniel, the prophet Daniel tested the effects of eating simply (a diet of pulse or lentils and other seeds) versus a kingly feast of meat and wine:

12Prove thy servants, I beseech thee, ten days; and let them give us pulse to eat, and water to drink.

13Then let our countenances be looked upon before thee, and the countenance of the children that eat of the portion of the king’s meat: and as thou seest, deal with thy servants.

14So he consented to them in this matter, and proved them ten days.

15And at the end of ten days their countenances appeared fairer and fatter in flesh than all the children which did eat the portion of the king’s meat.

ordering pizza in 2010

Data mining is the process of automatically searching large volumes of data for patterns. A simple example of data mining is its use for retail sales. If a clothing store records the purchases of customers, a data mining system could identify those customers who favour silk shirts over cotton ones.

Here's an example of data mining. Don't think this isn't going to happen because it is. And if this wasn't so funny, it would be really scary.

morocco's climbing goats

Goats on trees are found mostly only in Morocco. The goats climb them because they like to eat the fruit of the argan tree, which is similar to an olive. Farmers actually follow the herds of goats as they move from tree to tree. Not because it is so strange to see goats in trees and the farmers like to point and stare, but because the fruit of the tree has a nut inside, which the goats can't digest, so they spit it up or excrete it which the farmers collect. The nut contains 1-3 kernels, which can be ground to make argan oil used in cooking and cosmetics. This oil has been collected by the people of the region for hundreds of years, but like many wild and useful things these days, the argan tree is slowly disappearing due to over-harvesting for the tree's wood and overgrazing by goats.

As a result a group of people and organizations have banded together to try to save the tree. To do so one of the primary locations where the trees grow has been declared a biosphere preserve. It was also decided that by making the world aware of the oil, it's great taste and supposed anti-aging properties, would create a demand for it. However, the people who planned to market the oil could not envision people wanting to put an oil on their food or their face that was collected from goat excrement. As a result, a campaign is being led to ban grazing on the trees by goats during certain parts of the year to allow the fruit to ripen and fall off on its own. The fruit is then collected and turned into oil by oil cooperatives. So far, this arrangement seems to be working.

miss landmine

Angola is littered with thousands of landmines all over the country. In 23 years, over 80,000 people had died or lost limbs due to one wrong step.

To call attention to this problem and to raise funds to eliminate landmines, Norwegian artist Morten Traavik launched a controversial beauty pageant called Miss Landmine, where 10 women competed for the title of most beautiful mutilated Angolan woman, and the first prize of a leg prosthesis.


the most beautiful flower garden

The most beautiful and the most visited flower garden in the world is Keukenhof Gardens here in the Netherlands. It's a 70-acre showcase for the Dutch flower industry. Visitors can see a changing display of more than 7 million flowers - including some 1,000 varieties of tulips alone.

Where Keukenhof is situated now, was a hunting area in the 15th century. Herbs for the kitchen of the castle of Jacoba of Bavaria were also collected here; hence the name Keukenhof (keuken = kitchen, hof = garden).

denmark's black sun

During spring in Denmark, at approximately one half an hour before sunset, flocks of more than a million European starlings (sturnus vulgaris) gather from all corners to join in the incredible formations shown above. This phenomenon is called Black Sun (in Denmark), and can be witnessed in early spring throughout the marshlands of western Denmark, from March through to the middle of April. The starlings migrate from the south and spend the day in the meadows gathering food, sleeping in the reeds during the night.

Paul Rothemund compares his work to "casting a spell" -- and it does seem akin to magic. By writing a set of instructions, he can cause bits of DNA to fold themselves into a smiley face, a star, a triangle.

proven by science: messy beds are actually healthier !

Attention slobs! Tired of getting hassled by your parents/spouse/roommate for not making up your bed in the morning? Well, tell them that science has proven that messy beds are actually healthier:

Research suggests that while an unmade bed may look scruffy it is also unappealing to house dust mites thought to cause asthma and other allergies. A Kingston University study discovered the bugs cannot survive in the warm, dry conditions found in an unmade bed. […]

Researcher Dr Stephen Pretlove said: "We know that mites can only survive by taking in water from the atmosphere using small glands on the outside of their body.

"Something as simple as leaving a bed unmade during the day can remove moisture from the sheets and mattress so the mites will dehydrate and eventually die."

happy birthday, vacuum tube !

On November 16, 1904, British engineer John Ambrose Fleming patented the vacuum tube . This ushered in the age of modern electronics, leading to the development of radio, TV, and other forms of electronic equipment. Vacuum tubes were standard until the advent of the transistor. The US Supreme Court eventually invalidated Fleming’s patent, but he is still known as the inventor of the vacuum tube.

trap and torture

Tree ants (Allomerus decemarticulatus) in the Amazon construct elaborate traps for other insects they feed upon. They build these traps from tree fibers reinforced with fungus. When an unsuspecting insect encounters the trap, the ants emerge from hiding underneath and pull the prey’s legs to immobilize them, almost like a torture rack. Then they dismember the victim and carry the parts off to the colony. This method of “drawing and quartering” allows the ants to dine on insects much larger than themselves.


Yesterday I stumbled upon an article on unwarranted fears and discovered there was a phobia called Caligynephobia, the fear of beautiful women. At first I didn't believe someone could actually be afraid of a beautiful woman. But it's true, Caligynephobia does exist.

Caligynephobia, also called Venustraphobia, is the persistent and unwarranted fear of beautiful women, often experienced when physically interacting with an attractive female. Caligynephobia is estimated to effect approximately 0.47% of males in Britain, and 0.61% in America.

Its effects ultimately lead to a decrease in social and business activities, as communication with alluring women is generally attempted to be avoided where possible. Thus symptoms are easily detectible and mostly harmless. They include shortness of breath, irregular heartbeat, perspiration, nausea and overal feeling of dread.

For all those suffering from the fear of beautiful women, there's an effective treatment for Caligynephobia.

food chain fossil found

A vertebrate “food chain” fossil has been found in Germany. It was a shark that had eaten an amphibian that had eaten a fish. Scientists compared the fossil to Russian nesting dolls.

The fossilized trio lived 290 million years ago in the shallow coastal waters of a freshwater lake in the Saar-Nahe Basin of southwestern Germany. The lake had previously been linked to the sea but was landlocked for millions of years before the three animals lived and died.

Several pieces of evidence suggest the animals must have formed part of a single food chain.

placenta fools the immune system by acting like a parasite

Scientists had just discovered how placenta avoid being attacked by the mother’s immune system: it fools the body’s defenses by acting like a parasitic worm!

The placenta plays a vital role in pregnancy, acting as a link between the mother and foetus and providing it with essential nutrients.

However, as both the placenta and foetus have a different genetic make-up from the mother, in theory they are at risk of attack from her immune system.

The researchers already knew that the placenta secreted a small protein - neurokinin B (NKB) - which is found in significantly higher levels in mothers when pre-eclampsia develops. […]

However, they found that the placental form of the protein did not react in the same way as the form they had been using in the laboratory.

It was clear that a modification was occurring during the synthesis of the protein by the placenta. Further investigation revealed that placental NKB contained the molecule phosphocholine, which is used by the parasitic nematode worm to avoid attack by the immune system of the host in which it lives.

one man band


violent sex

The gruesome behavior or the male African bat bug (Afrocimex constrictus) is directed at other bat bugs. Instead of copulating via the female’s sex organs, he will stab her abdomen to release sperm directly into her bloodstream. So the females have evolved paragenitals, a “spongy reservoir of immune cells” as a defense against these tactics. But since male bat bugs are not particular when it comes to mating, some male bat bugs have also developed paragenitals to defend themselves against sexual attack!
