One Animal's Body, Another Animal's Brain

Posted: 09 Jun 2011 05:05 AM PDT

Recent advances in genetic research have allowed scientists to grow the brain of one animal inside he body of an entirely different species. Is this the dawning of a new era or a scene out of The Island of Dr. Moreau?

The idea of splicing animals together isn’t a new one The ancient Greeks fashioned a chimera out of a snake, a goat, and a lion; the Japanese made a baku out of an ox, an elephant, and a tiger. Even today, people are inventing new creatures -only now, they’re using a lot more than their imaginations.

Just ask biologist Todd Streelman. Inside his lab at Georgia Tech, Streelman successfully bred a living animal with the brain of anther species. He started with a cichlid, a type of fish found in Lake Malawai, at the southern tip of Africa’s Great Rift Valley. Over the past 500,000 years, hundreds of different species of the cichlid have evolved from a single ancestor, with each new species developing a distinct set of jaws, teeth, brain, and behaviors to fit their respective environments. Streelman took two species of cichlid fish -rock-dwelling cichlids and sand-dwelling cichlids- and figured out a way to grow a sand-dweller’s brain inside the skull of a rock-dweller. From a distance, that might seem like a simple trick in cross-pollination. But it’s no small feat when you consider that the brains of the two creatures are as different as those of chimpanzees and humans.

Todd Streelman

ANIMAL CROSSING

How’d he do it? The trick to Streelman’s success was figuring out how (and when) the brains of different species distinguish themselves during embryonic development. In the earliest stages of life, the brain of almost every animal starts out looking the same. It begins as a small sheet of rapidly dividing cells that are not yet designed for different functions. But this sheet of cells eventually rolls into a tube, and the cells turn into different types of neurons. The neurons then slowly forms connections uniquely tailored to the creature’s lifestyle. In humans, for example, the brain develops a large cerebral cortex capable of processing language and consciousness. In various species of cichlid fish, the forebrain changes and grows depending on its future environment. More specifically, the sand-dweller’s forebrain develops a large hind region for surviving in open water, while the rock-dweller’s forebrain develops a large front region to navigate Lake Malawi’s murky, cavernous bottom.

In both species, the size and shape of the forebrain is determined by the expression of a gene called Wnt1. In sand-dwellers, this gene sends out a strong signal, while in rock-dwellers, Wnt1’s signal is weak. As part of his study, Streelmen took rock-dweller embryos and placed them in water treated with lithium chloride -a salt that’s known to increase the strength of the Wnt1 signal. This caused the rear section of the rock-dweller’s brain to grow until its brain looked like that of a sand-dweller. In other words, by simply  changing the expression of a single gene, Streelman was able to Frankenstein a new fish.

Cichlid embryo

OF MICE AND MEN

While Streelman has proven that he can grow one species’ brain inside another’s body, there’s no telling if his patchwork creations can survive in their natural environments. To date, most attempts to manipulate neural development in animals have led to brains that look promising in the land but fail to function in the real world. In 2002, for instance, researchers manipulated a mouse’s genetic signals to increase the size of its cerebral cortex. The cortex grew dramatically, forming folds indicative of the intelligence in high-order mammals and humans. But the mutation proved fatal, and the mouse died before it was born.

Some scientists posit that the mouse’s death may have had more to do with the complex relationship between the animal and environment and less to do with ill-suited manipulation. Georg Striedner, and evolutionary biologist at the University of California at Irvine, has found that many animals go through a phase during early development in which they’re particularly vulnerable to injury, starvation, or disease. In order for an animal to survive, something in their external world has to protect them. For instance, many species go through a prolonged period of rapid cell division before their brains become neurons. This ultimately leads to a larger brain, but it also means that the animal’s brain is not fully formed at birth. Parrots are a good example. After parrots hatch, their brains aren’t particularly developed, which forces the babies to rely on their mothers for food. That means that the mothers’ feeding behaviors must have evolved at the exact same time that parrots evolved to have larger brains. Otherwise, parrots would have never become so smart.

Cichlid fish

The process of evolving new traits is clearly complicated. Labs can create animals with shiny new traits, but that doesn’t mean the animals can handle the complexity of the world around them. As for Streelman’s fish, no one knows how their manipulated brains will affect their behavior -or, for that matter, how they’ll fare in nature. In many ways, though, that isn’t the point. The goal of Streelman’s research isn’t to grow new and funky animals; it’s to learn how animals evolve. By discovering the relationship between the animal’s genome and its brain development, scientists ultimately hope to pinpoint the genetic basis of of human thought and behavior. It just may be that, along the way, creatures like the chimera and the baku become more than the stuff of ancient folklore.

A Tongue Stud Can Give Paralyzed People Greater Control Over Mobility Devices

Posted: 09 Jun 2011 04:55 AM PDT

Martin Mireles has been paralyzed from the neck down for nearly twenty years. He can maneuver a mobility chair by steering it with his mouth, but a new magnetic tongue stud developed by researchers at the Northwestern University School of Medicine makes it a lot easier:

Mr. Mireles, 37, tested the equipment one recent afternoon by guiding a wheelchair through an obstacle course lined with trash cans. Mouth closed, he shifted the magnet to travel forward and backward, left and right.[...]

To operate the system, the user wears a headset with sensors that pick up magnetic signals from the tongue ring. Moving the tongue to the mouth's upper left corner, for instance, moves the wheelchair forward. (The researchers hope that in the future, touching each tooth could signal a different command, from turning on the television to answering the phone to opening a door.)

Researchers decided to use the tongue because they wanted to take advantage of some of the functions a severely disabled person still had. The tongue does not tire easily, they said, and it is not usually affected by a spinal cord injury because it is directly connected to the brain through a cranial nerve.

More like FAKEbook Tattoo, Am I Right?

Posted: 08 Jun 2011 08:30 PM PDT

So it seems Susyj87’s briefly infamous Facebook friends tattoo was a hoax. Not only was the tattoo a fake (a transfer that only lasted a few days), but the video itself was a promo piece for a company called Pretty Social that makes custom gift items using your Facebook photos. As much as I hated the idea of a woman walking around with 152 faces permanently stamped on her arm, I hate this even more.

Apparently, high school in the 70s was more far-out than I thought. According to the YouTube poster, this was from a 70s-era science class video; the lecture at the beginning was removed to highlight the wicked groovy dance-athon. I can’t say I learned anything from this, but everyone really seems to be enjoying their time in Biology II.

Pomander Walk: The Old English Street in the Heart of New York City

Posted: 08 Jun 2011 07:31 PM PDT

Pomander Walk is a little neighborhood on Manhattan that was designed to look like an London street composed of Tudor-era houses. Inspired by a popular 1910 play called Pomander Walk, it was built by a somewhat eccentric nightclub owner in 1921:

Named Pomander Walk (of course!), this little alley way goes unnoticed by most everyone not previously aware of its location. From the main street (see the 94th Street view here and the 95th Street view here), most passersby would walk by without ever thinking that this picturesque little mini-village exists in the Big Apple.

The houses are tiny. Each is divided into two one-floor apartments; each apartment measures roughly 700 square feet. By necessity, some have kitchenettes (instead of full kitchens), using a closet to house the refrigerator. And some of the houses have external dumbwaiters, designed (most likely) as makeshift garbage chutes.

Five artists walked into the Fancy Grocery convenience store in New York City’s West Village and bought each and every item. By the end, Hercules, the owner, was completely depleted of his inventory and had rung up each purchase on two rolls of receipt paper. Today, those artists are exhibiting their finds at 57 Stanton Street.

Among the items for sale: a Coke can for $150. Is that too much? Keep in mind that the artists cleverly inverted it, thus increasing its artistic value.

No, Seriously, It's Not Safe to Ride in the Bike Lane

Casey Neistat got a ticket for riding his bicycle outside of a bike lane in New York City. He argued with the police officer that sometimes he does so because there are obstructions that make it unsafe to use the designated lane. The cop didn’t care, and issued him the citation anyway.

To prove his point, Mr. Neistat made this video, showing how dangerous it would be to comply with the law…by crashing his bike, over and over again into road hazards. He saved the best for last.

Sparky's First And Only Batch Of Cicada Ice Cream Sold Out

Posted: 08 Jun 2011 01:11 PM PDT

Sorry folks, Sparky’s Homemade Ice Cream in Missouri will not be making any more cicada ice cream for the time being after receiving advice from the public health department. This will disappoint the many customers who made this unique flavor a runaway hit. It was so popular that it sold out Wednesday, June 1 before it was to make its grand debut on Thursday.

Employees collected the cicadas in their backyards and removed most of the dead bugs’ wings. They then boiled the bountiful bugs and covered them in brown sugar and milk chocolate. The base ice cream is brown sugar and butter flavour.

Does this sound like a tasty treat to you?

7-Year-Old Is an Accidental Art Sensation

Posted: 08 Jun 2011 09:47 AM PDT

Leilah Poulain’s mom isn’t super-handy with Facebook. In an attempt to showcase her daughter’s painting of a penguin (above), she mistakenly uploaded the file to a public folder meant for entrants to a contest. The winner of that contest would have their artwork showcased in the Saatchi Gallery, a world-famous contemporary art gallery.

'A year later I'd forgotten about it, and then I got an email saying Leilah was a Saatchi winner,' said Rebekah.

I called them and said, "Thank you, but I don't know what you're on about".

Apparently there were 1,700 applicants – but Leilah wasn't actually one of them. Not on purpose.

'It was quite funny really. I told my brother, who's a graphic designer, and he couldn't believe it. He said he'd love to exhibit at the Saatchi Gallery.'

Yesterday, Leilah's painting was hanging on the wall of a gallery which features work from the likes of Damien Hirst and Tracey Emin.

Rebekah added: 'It seems it all happened because I'm such an idiot. I didn't know what I was doing when I uploaded Leilah's picture.

'When I told her the picture was going to be in a gallery, she thought it was brilliant.

'Leilah said, "Does this mean I'm a famous artist?". She wants to go to see it in London now.'

For those of you that treat your smart phone and tablet like it's your best friend, you may now be able to get one step closer to having an actual companion. Google and the company iRobot have teamed up to create the AVA robot which rolls on wheels and uses a tablet computer as its "head."

AVA is a pedestal shaped bot on wheels which can autonomously navigate itself through a crowd without breaking anyone's ankles. While containing a great deal of its own functionality, AVA's head is a tablet computer. Any tablet computer. iPad2, Galaxy, you name it – iRobot claims they want AVA to be "head agnostic".

Top 10 Most Extreme Substances

Posted: 08 Jun 2011 09:20 AM PDT

What are the most extreme substances in the world? No, not Mountain Dew;  this list compiles and gives the details on the hottest, most flammable and most acidic substances known to man. One of which can melt through twelve layers of concrete.

What do you get when you stack carbon nanotubes on their ends and sandwich them together? A material that absorbs 99.9% of the light that touches it. The microscopic surface of the material is rough and uneven, which breaks up the light and makes it a poor reflector. Then add to that carbon nanotubes act as superconductors in certain arrangements, which makes them excellent light absorbers, and you have a perfect storm of black.

Of All of The People In All The World in Rice

Posted: 08 Jun 2011 09:19 AM PDT

The exhibit "Of All The People in All The World" is traveling the world to show all the people exactly how many of them there are by using rice. Sometimes it's hard to get your mind around millions and billions of humans and their varying statistics. By representing each person as a single piece of rice this showcase helps people understand varying numbers such as how many people have walked on the moon and the population of the United States (pictured). See link for more in depth video.

The show adapts to its setting: the country, city and building it is in. The amount of rice used varies according to which version is performed, Of All The People In All The World: UK is a standard small version using 1,000Kg of rice to represent 60,000,000 people. Of All The People In All The World: Europe at 12,000Kg is an example of a medium size version. So far there has been a single presentation of Of All The People In All The World in which the whole world’s population was represented by 104 tons of rice in Stuttgart.
