The Electric Eel (Electrophorus electricus) is truly a wonder of the animal kingdom, and an amazing work of millions of years of evolution.

Despite its name it is in no way closely related to eels, it is a member of the Knifefish family and is the only member of its genus. The electric eel lives in fresh water in the Amazon, as well as other river basins in south america. They can grow to about 2m in length (6 and a half feet) weighing 20 kg. It can produce an electric shock of up to 600 Volts!

It produces this shock using 3 organs, the Main organ, the Hunters organ, and the Sachs organ. The total size of these 3 organs make up an amazing four fifths of the eels body! The organs are made of electrocytes, and are lined up so that a current can be passed from one organ to the next. When the eel wants to produce a shock it opens up glands in and between the organs allowing sodium ions to flow between them, creating a sudden change in potential difference (voltage.)

The shock only lasts approximately 0.2 milliseconds meaning it is not very likely to be lethal to an adult human despite it being 600 volts. That being said, it has been known to kill if the shock is, for example, directed towards the heart.

After spending years developing a simple machine to make inexpensive sanitary pads, Arunachalam Muruganantham has become the unlikely leader of a menstrual health revolution in rural India. Over sixteen years, Muruganantham’s machine has spread to 1,300 villages in 23 states and since most of his clients are NGOs and women’s self-help groups who produce and sell the pads directly in a “by the women, for the women, and to the women” model, the average machine also provides employment for ten women. 

Muruganantham’s interest in menstrual health began in 1998 when, as a young, newly married man, he saw his wife, Shanthi, hiding the rags she used as menstrual cloths. Like most men in his village, he had no idea about the reality of menstruation and was horrified that cloths that “I would not even use… to clean my scooter” were his wife’s solution to menstrual sanitation. When he asked why she didn’t buy sanitary pads, she told him that the expense would prevent her from buying staples like milk for the family. 

Muruganantham, who left school at age 14 to start working, decided to try making his own sanitary pads for less but the testing of his first prototype ran into a snag almost immediately: Muruganantham had no idea that periods were monthly. “I can’t wait a month for each feedback, it’ll take two decades!” he said, and sought volunteers among the women in his community. He discovered that less than 10% of the women in his area used sanitary pads, instead using rags, sawdust, leaves, or ash. Even if they did use cloths, they were too embarrassed to dry them in the sun, meaning that they never got disinfected — contributing to the approximately 70% of all reproductive diseases in India that are caused by poor menstrual hygiene. 

Finding volunteers was nearly impossible: women were embarrassed, or afraid of myths about sanitary pads that say that women who use them will go blind or never marry. Muruganantham came up with an ingenious solution: “I became the man who wore a sanitary pad,” he says. He made an artificial uterus, filled it with goat’s blood, and wore it throughout the day. But his determination had severe consequences: his village concluded he was a pervert with a sexual disease, his mother left his household in shame and his wife left him. As he remarks in the documentary “Menstrual Man” about his experience, “So you see God’s sense of humour. I’d started the research for my wife and after 18 months she left me!”

After years of research, Muruganantham perfected his machine and now works with NGOs and women’s self-help groups to distribute it. Women can use it to make sanitary napkins for themselves, but he encourages them to make pads to sell as well to provide employment for women in poor communities. And, since 23% of girls drop out of school once they start menstruating, he also works with schools, teaching girls to make their own pads: “Why wait till they are women? Why not empower girls?” 

As communities accepted his machine, opinions of his “crazy” behavior changed. Five and a half years after she left, Shanthi contacted him, and they are now living together again. She says it was hard living with the ostracization that came from his project, but now, she helps spread the word about sanitary napkins to other women. “Initially I used to be very shy when talking to people about it, but after all this time, people have started to open up. Now they come and talk to me, they ask questions and they also get sanitary napkins to try them.”

In 2009, Muruganantham was honored with a national Innovation Award in 2009 by then President of India, Pratibha Patil, beating out nearly 1,000 other entries. Now, he’s looking at expanding to other countries and believes that 106 countries could benefit from his invention. 

Muruganantham is proud to have made such a difference: “from childhood I know no human being died because of poverty — everything happens because of ignorance… I have accumulated no money but I accumulate a lot of happiness.” His proudest moment? A year after he installed one of the machines in a village so poor that, for generations, no one had earned enough for their children to attend school. Then he received a call from one of the women selling sanitary pads who told him that, thanks to the income, her daughter was now able to go to school.

And then there’s good ol’ America

This actually makes me so angry. The truth is right here and people see it and brush it aside. We really could make things better. But no, America apparently wants to suck forever.

You know, America, if we spent some money investing in education instead of making sure the ultra-rich were even more ultra-rich, we could *actually* be the exceptional nation that we pretend to be.

So, my sister is an Education Policy major and she’s all about reforming our system, but she says comparisons like this don’t really work. The problem with comparing us to other nations, particularly those in Asia and Scandinavia, is that they are predominantly monocultures. There’s less racial and economic disparity which makes one solution work for more people. The biggest challenge of the American education system (and perhaps its greatest strength) is it has to adapt to a variety of cultures, peoples and backgrounds.

Standardized tests are still the worst though.
