Science Fact Friday: Tetrodotoxin, ft. a small gif because I’m avoiding my real obligations. Why does tetrodotoxin not affect its host? More studies need to be done but at least a few species possess mutated sodium ion channels. The tetrodotoxin can’t interact efficiently with the altered channels.
Another interesting tidbit: Animals with tetrodotoxin can lose their toxicity in captivity. It is suspected that the animals accumulate the toxic bacteria as a side-effect of their diet. After several years of captivity on a tetrodotoxin-bacteria-free diet, the bacterial colonies living in the animals die, residual toxin is cleared from the system, and the animal is safe to handle.
In 1968, Reiko Weston opened her new Fuji-Ya restaurant built atop the limestone foundation of a 19th-century flour mill overlooking the Mississippi River and the Stone Arch Bridge. The original Fuji-Ya restaurant operated near 8th St. and LaSalle beginning almost a decade earlier, in 1959, and served fine Japanese food including Charcoal-Broiled Teri-Yaki dinners, seafood dishes, soups, rice plates, and more. Fuji-Ya translates to “second to none” and the new restaurant offered a dining experience like no other in the Twin Cities.
Weston’s restaurant business expanded over the years with Taiga, a Chinese Szechwan restaurant in St. Anthony Main, and The Fuji International in Cedar-Riverside neighborhood, which featured Korean, Chinese, and East Indian food in addition to Japanese food. Her restaurants received numerous awards and Weston herself was named Minnesota Small Business Person of the Year in 1979.
After Reiko Weston passed away in 1988, her daughter Carol stepped in to manage. But in 1990, the City of Minneapolis bought out the historic restaurant in order to make way for the newly designed parkway. About a decade later, Fuji Ya was brought to life again in Uptown in the trendy Lyn-Lake area, where it remains today.
Recently, Fuji-Ya has gained renewed attention as the Park Board makes plans for a $12 million riverfront refresh. Plans include the teardown of the old Fuji-Ya building, expansion of green space, improved pedestrian crossings, and the addition of a new riverfront restaurant. It was announced last week that Sioux Chef owners Sean Sherman and Dana Thompson will open Owamni: An Indigenous Kitchen on the site.

These travel booklets from throughout the UK were collected by Barbara Denison over the course of three decades, part of a larger collection consisting of dozens of volumes. Text-dense and diagram-heavy guides like these were meant to both give guidance while visiting and act as inexpensive momentos afterwards. Most of the booklets in the collection concern cathedrals, abbeys, and ruined castles that Denison visited over the course of her travels.
Ah, romantic love; beautiful and intoxicating, heart-breaking and soul-crushing… often all at the same time! Why do we choose to put ourselves though its emotional wringer? Does love make our lives meaningful, or is it an escape from our loneliness and suffering? Is love a disguise for our sexual desire, or a trick of biology to make us procreate? Is it all we need? Do we need it at all?
If romantic love has a purpose, neither science nor psychology has discovered it yet – but over the course of history, some of our most respected philosophers have put forward some intriguing theories.
1. Love makes us whole, again / Plato (427—347 BCE)
The ancient Greek philosopher Plato explored the idea that we love in order to become complete. In his Symposium, he wrote about a dinner party at which Aristophanes, a comic playwright, regales the guests with the following story. Humans were once creatures with four arms, four legs, and two faces. One day they angered the gods, and Zeus sliced them all in two. Since then, every person has been missing half of him or herself. Love is the longing to find a soul mate who will make us feel whole again… or at least that’s what Plato believed a drunken comedian would say at a party.
2. Love tricks us into having babies / Schopenhauer (1788-1860)
Much, much later, German philosopher Arthur Schopenhauer maintained that love, based in sexual desire, was a “voluptuous illusion”. He suggested that we love because our desires lead us to believe that another person will make us happy, but we are sorely mistaken. Nature is tricking us into procreating and the loving fusion we seek is consummated in our children. When our sexual desires are satisfied, we are thrown back into our tormented existences, and we succeed only in maintaining the species and perpetuating the cycle of human drudgery. Sounds like somebody needs a hug.
3. Love is escape from our loneliness / Russell (1872-1970)
According to the Nobel Prize-winning British philosopher Bertrand Russell we love in order to quench our physical and psychological desires. Humans are designed to procreate; but, without the ecstasy of passionate love, sex is unsatisfying. Our fear of the cold, cruel world tempts us to build hard shells to protect and isolate ourselves. Love’s delight, intimacy, and warmth helps us overcome our fear of the world, escape our lonely shells, and engage more abundantly in life. Love enriches our whole being, making it the best thing in life.
4. Love is a misleading affliction / Buddha (~6th- 4thC BCE)
Siddhartha Gautama. who became known as ‘the Buddha’, or ‘the enlightened one’, probably would have had some interesting arguments with Russell. Buddha proposed that we love because we are trying to satisfy our base desires. Yet, our passionate cravings are defects, and attachments – even romantic love – are a great source of suffering. Luckily, Buddha discovered the eight-fold path, a sort of program for extinguishing the fires of desire so that we can reach ‘nirvana’ – an enlightened state of peace, clarity, wisdom, and compassion.
5. Love lets us reach beyond ourselves / Beauvoir (1908-86)
Let’s end on a slightly more positive note. The French philosopher Simone de Beauvoir proposed that love is the desire to integrate with another and that it infuses our lives with meaning. However, she was less concerned with why we love and more interested in how we can love better. She saw that the problem with traditional romantic love is it can be so captivating that we are tempted to make it our only reason for being. Yet, dependence on another to justify our existence easily leads to boredom and power games.
To avoid this trap, Beauvoir advised loving authentically, which is more like a great friendship: lovers support each other in discovering themselves, reaching beyond themselves, and enriching their lives and the world, together.
Though we might never know why we fall in love, we can be certain that it’ll be an emotional rollercoaster ride. It’s scary and exhilarating. It makes us suffer and makes us soar. Maybe we lose ourselves. Maybe we find ourselves. It might be heartbreaking or it might just be the best thing in life. Will you dare to find out?

I am pretty sure that this cannot be true because I saw an ad from the corn industry that said high fructose corn syrup is good for you…
A range of diseases – from diabetes to cardiovascular disease, and from Alzheimer’s disease to attention deficit hyperactivity disorder – are linked to changes to genes in the brain. A new study by UCLA life scientists has found that hundreds of those genes can be damaged by fructose, a sugar that’s common in the Western diet, in a way that could lead to those diseases.
However, the researchers discovered good news as well: An omega-3 fatty acid known as docosahexaenoic acid, or DHA, seems to reverse the harmful changes produced by fructose.
“DHA changes not just one or two genes; it seems to push the entire gene pattern back to normal, which is remarkable,” said Xia Yang, a senior author of the study and a UCLA assistant professor of integrative biology and physiology. “And we can see why it has such a powerful effect.”

Americans get most of their fructose in foods that are sweetened with high-fructose corn syrup, an inexpensive liquid sweetener made from corn starch, and from sweetened drinks, syrups, honey and desserts. The Department of Agriculture estimates that Americans consumed an average of about 27 pounds of high-fructose corn syrup in 2014. Credit: © AlenKadr / Fotolia

How many did you know? All worth reading more about!!
1. Hundreds of genes spring to life after you die - and they keep functioning for up to four days.
2. Livers grow by almost half during waking hours.
3. The root cause of eczema has finally been identified.
4. We were wrong - the testes are connected to the immune system after all.
5. The causes of hair loss and greying are linked, and for the first time, scientists have identified the cells responsible.
6. A brand new human organ has been classified - the mesentery - an organ that’s been hiding in plain sight in our digestive system this whole time.
7. An unexpected new lung function has been found - they also play a key role in blood production, with the ability to produce more than 10 million platelets (tiny blood cells) per hour.
8. Your appendix might actually be serving an important biological function- and one that our species isn’t ready to give up just yet.
9. The brain literally starts eating itself when it doesn’t get enough sleep. brain to clear a huge amount of neurons and synaptic connections away.
10. Neuroscientists have discovered a whole new role for the brain’s cerebellum - it could actually play a key role in shaping human behaviour.
11. Our gut bacteria are messing with us in ways we could never have imagined. Neurodegenerative diseases like Parkinson’s might actually start out in the gut, rather than the brain, and there’s mounting evidence that the human microbiome could be to blame for chronic fatigue syndrome.
Starting in the mid-seventh century, the Japanese government placed a ban on eating meat which lasted on and off for over 1,200 years. Probably influenced by the Buddhist precept that forbids the taking of life, Emperor Tenmu issued an edict in 675 CE that banned the eating of beef, monkeys, and domestic animals under penalty of death. (Side note: monkey must have been very popular to be named specifically in the law!) Emperor Tenmu’s original law was only meant to be observed between April and September. But later laws and religious practices essentially made eating most meat, especially beef, illegal or taboo.
It was not until 1872 that Japanese authorities officially lifted the ban. Even the emperor had become a meat eater, to show it was totally okay and not angering Buddha. While not everybody was immediately enthused, particularly monks, the centuries-old taboo on eating meat soon faded away.
Once again we bring you a portion of the educational series Man: A Course of Study. This booklet uses the Herring Gull to teach innate and learned behaviors. We wish we knew who the illustrator of this booklet was because they’ve done a great job helping us understand how baby bird brains work.
Man: A Course of Study was developed by Jerome S. Bruner, an American psychologist who wanted to build a curriculum to teach fifth graders about what it is to be human. He often used animals as contrast to help explain the biological nature of humans.
From the teaching series, Man: A Course of Study published by Curriculum Development Associates. Our copy is the first commercial edition published in 1970.
