Random Thought of the Day

Ancient penguins!!!



Some paleontologists in Peru recently discovered a 36 million year-old penguin fossil! This guy is a HUGE! About twice the size of an emperor penguin! Woah!


P.S. This artist's rendition is not the species that was just recently discovered, however, it's about the same size, so I thought I'd show it to you anyway.

Also, unlike modern-day penguins, these guys don't wear the typical penguin tuxedo. Instead, they have brown bellies and gray tops. I like the new wardrobe selection.



Check out the full article here at the NY Times! AND there's this cool video from NatGeo:

Uh oh... MORE NUDIS!!!

Ok, so these are LOCAL nudibranchs.

Check it; you can find them in the Sound!!!

First is the Giant nudi, Dendronotus iris, is the biggest nudi in the world reaching lengths of more than 30cm!!! Wait, they get cooler. When threatened, they can jump off the ground and swim away! These guys feed only on tube anemones!

Also, they come in many different colors. For example:




Next is a "mystery" animal found in someone's sewer... Surprise! It's a nudibranch! Bet you didn't guess that one!

This is Onchidoris bilamellata or the rough-mantled doris. They're kinda ugly, but they do this really nifty thing during breeding season. Literally thousands of these nudis will congregate and start swarming, slowly crawling in one direction. They all start to follow the slime trails (mucus) of the individual in front of them, forming lines of nudis several hundred long! So COOL!

MORE Nudis!!!

I have come to the conclusion that everyone likes nudibranchs. Besides the fact that they are so cute and pretty, they are also REALLY FREAKING COOL!!!

Almost ALL nudis (pronounced like nudies) are specialized to eat ONE type of animal! For example, there are some that eat only anemones. When they eat these anemones, they will absorb the stinging cells from the anemone and add them to their own "tentacles" (actually, those furry, tentacle-like things are called cerata). And these same nudis will also start secreting mucus that can protect them from the anemone's stingers!

But here's a nudi that specializes in eating OTHER NUDIS!!!

It's really beautiful and yet, very sad at the same time.

Hope you enjoy!

Whoa, I have just seen into my future...

This video was AWESOME!

Well, you might not enjoy learning about the history of ornithology as much as I do, but this short talk is still quite comical.

Actually, in the next 30 years, I will probably end up becoming this man...making jokes about phallic fungi, over-sized testes, and promiscuous female birds...
Yes, definitely me in 30 years.

Also, Mr. Birkhead talks about an example of how this "frivolous field" of ornithology actually has "real-world" significance! Just for you, Mom!

Random Thought of the Day

Here's an absolutely mind-blowing TED lecture presented by an exploration expert. Bill Stone, deep cave explorer, was commissioned by NASA to design a mission to Europa in search of extra-terrestrial life. He used his extensive experience exploring the unknown depths of our own planet to design a robot capable of autonomously exploring, documenting, and analyzing the unknown depths of the Europan oceans. But then he goes on to propose a truly radical idea. Bill Stone wants to build a fueling station in space! And not only that, but he claims that he can do it in the next 7 years using less than one trillion dollars!!!

This man is crazy, but might actually revolutionize space travel in the next 20 years.

The oldest living things in the world

Can you guess the age of the world's oldest living organism?

2,000 years old? Nope.

4,000 years old? Not even close.

10,000 years old? Still not close.

100,000 years old? Warmer, but no.

The oldest living thing on Earth is more than 500,000 years old. That's half a MILLION years old!!!

Artist, philosopher and biologist Rachel Sussman has spent the last five years traveling the globe in search of the world's oldest living things. She sees this project as an opportunity for humans to reconsider our idea of time. Watching her presentation from the TED Global 2010 conference has helped me fully comprehend the insignificance of this little blip we call humanity. Again, I am left to wonder why humans continue to pretend to be superior to all other life on Earth. I don't understand how we ever got this idea in our heads. Clearly we just don't look around enough anymore.

Take a moment to look around you every once in a while...

Have you ever heard a male lyrebird sing? No? You are missing out on LIFE!!!

David Attenborough does a nice little segment on this astounding vocalist in his series called The Life of Birds.



Not only is this footage absolutely amazing, but I also loved the subtle commentary on human impacts in the forest. Lyrebirds aren't supposed to be singing like chainsaws...

Since that last one was so lengthy...

Here's a quick and dirty post to fulfill your ADHD needs:

The Power of Words

This has been on my mind for the past few weeks now and it has been drastically changing my outlook on everything that I think and do. (If you'd rather not read this entire thing, you can just skip to the end...)


Words are extremely powerful. But not in the way I know you're thinking. Not in the sense that Obama's speeches are powerful or the words of the Bible are powerful. A single word is powerful simply by existing.

Here's an extremely simple example. Does an abstract thing such as an "idea" even exist if we don't have a word for talking/thinking about it?  Think about that for a second.

Now extrapolate this idea to encompass this entire internal conversation you are having with me. What if we didn't have a word for ideas? or thinking? or thinking about what someone else is thinking? We would be completely incapable of having this internal dialogue. Not only would we be unable to physically converse about this (face to face, verbally), but you would be unable to THINK about it. You would not be able to COMPREHEND this idea.

Do you understand? No?

Ok, here's another example:

In the 1970s, Nicaragua created the country's first clinic for the deaf and mute. Before this time, deaf people in Nicaragua had no standard form of communication. After the creation of this clinic, a small group of Nicaraguans INVENTED their own form of sign language. The first version of this language only had two words for thinking about other people's thoughts. Today, new children are learning this form of sign language and have invented new words. This new generation of signers has seven signs for thinking about other people's thoughts.

Researchers gave these two generations of signers a simple test to quantify their ability to think about other people's thoughts. The researchers gave each subject a comic strip showing a boy playing with a train set. The boy's little sister wants to play with the train too but her brother won't share. Then the boy packs up the train set, puts it into the toy chest and leaves the room. Once he is gone, the little sister sneaks into the room, takes the train out of the chest and hides it under the bed. When the boy gets back to the room, the researchers ask the subject (in sign, of course), "Where will the little boy look to find his train set?"

The first generation of signers (with only 2 words for thinking about other people's thoughts) all answered, "He will look under the bed, of course."  The new generation of signers (with 7 words for thinking about other people's thoughts) all answered, "He will look in the toy chest because he thinks that the train is still there."

Clearly, we can understand that the little boy THINKS his train is in the chest. People without words for thinking about other people's thoughts are actually INCAPABLE of thinking about other people's thoughts.

Without a word for it, we cannot comprehend it! Wait a second. If we cannot comprehend it, does it even exist?

Listen to the whole story courtesy of Radiolab!!!


Wait, think about this for a moment: What if we didn't have language...

Would we even be capable of thought?

Scientists have researched this, of course. And no, without language -- without words -- we are incapable of thought.

In the most recent episode of Radiolab, researchers in Nicaragua discovered a perfectly intelligent man who had lived his entire life without any form of language. Imagine living 27 years without language or "thought." No, you can't. Is it really possible for us to think about what it's like not to think? RadioLab discusses it here:



Maybe it IS possible to understand what it's like not to have language. RadioLab interviewed a neurologist who had a stroke that slowly caused her to lose language. She describes her experience and what it felt like to be incapable of thought here:



Ok. If you made it through that whole post and still understand what's going on, you are pretty much amazing. If you would rather not read everything you can just listen to the whole RadioLab broadcast HERE!

It pretty much changed my life. No joke.

Whoa! Diatom Madness!!!

Do you know what a Diatom is? Of course you do, but here's a short review just in case you forgot.

Diatoms are these cute little aquatic, single-celled, algae-like phytoplanktons. They photosynthesize, making food from sunlight and producing oxygen from carbon dioxide. Instead of constructing cell walls from cellulose or phospholipids like plants and animals, they make cell walls out of silica -- glass! This little glass house is called a frustule. Each frustules is distinct for each species of diatom, and when the diatom dies and decomposes, its silica house remains.

Check it out!


This is a dead diatom called Actinocyclus.

Here's one that is still alive!


But that's not the best part. There are some people who like diatoms so much they will PAY people to collect them and arrange them into pretty little shapes...


And some of these shapes get completely crazy



Wait, it gets better!



This last one is from the late 19th century when collectors first started commissioning and paying people for little arrangements of these single-celled plankton. This one actually has butterfly scales in it as well.

Isn't that crazy?!  For Elements this year, I am planning on making an attempt at constructing my own diatom image. I'll let you know when that happens, of course!

You can take a full tour of cool diatom images here!

But I have one more before I go


Soooo COOL!

In the news this week...

The NY Times, in the Tuesday issue of the Science Times, reported on animal hybrids! Who doesn't love a cool hybridized animal or plant?

I'm sure that you've probably heard of things like ligers before, but have you ever seen a wolphin? or a Pizzly Bear? Zorse? Yeah, pretty neat, huh?


The Sea Life Park in Hawaii inadvertently created a cross between a dolphin and a false orca, calling it a wolphin. A hunter in Canada shot a huge white and brown bear with long claws and a hump on its back. Scientists later discovered that it was a polar bear-grizzly hybrid.


These kinds of animals exist all over the place and some of them aren't completely unnatural. Sometimes these hybridizations create an organism better capable of surviving in a new, changing environment. This can create completely new species! Speciation by hybridization might become a more prevalent occurrence in today's rapidly changing ecosystems, especially as habitats begin to overlap, allowing geographically isolated species to interact. This habitat overlap has caused the creation of Pizzly bears in the Arctic and Subarctic of Canada.

Keep your eyes open for more of this kind of thing in the future!

Nudibranchs! The distant, much cuter cousins of snails and slugs.

Aren't they pretty?!

Wait, you don't think that's pretty? What about these?




Yeah? They're freaking ADORABLE!!! Too bad some of them (the cnidarian eating ones) incorporate whole nematocysts into their cerata. That means some of them steal the stinging parts of jellyfish and incorporate them into their own little tentacle-y things. No one knows how they do this, by the way. Think about this for a second; How on EARTH does this guy manage to grow the cells of a completely different animal in its own body? We humans have problems sharing blood with each other! These guys are literally stealing ORGANS from other animals! CRAZY!

Ok, you still don't think they're cute?

What about this one?

I knew I'd get you with that guy!
He's just so happy to see you!!!

Random Thought of the Day

What if you discovered an ancient tome that was so old, it was impossible to open and read its contents... How on Earth would you ever manage to discover the wealth of information hidden between its covers? Imagine all the discoveries and insight Man would miss out on...

Solution!!!

Just CT scan that shit!

Researchers at the University of Texas in Austin were granted permission to scan a book printed in 1584 by Pedro Orcharte of Mexico. They left the tome inside its protective case and scanned 782 pages using X-ray CT technology, allowing researchers to digitally open the book and read its contents without ever turning a page!



In case you didn't know, CT stands for computed tomography, which, in case you didn't know, is the process of scanning various 2D "slices" of a 3D object in order to visualize the whole object digitally. In the case of this ancient tome, each "slice" that the researchers scanned was a different set of pages. The x-rays used in the CT scan are reflected by the iron in the ink on each page allowing researchers to piece together the entire book one page at a time.

Now if only they could read Latin...

Check out some more info on this really cool scanning method HERE!

Random Thought of the Day

Guam.

I recently educated myself about the interesting plight of Guam. This little island in Micronesia (it's actually petty large) is an organized, unincorporated territory of the United States. That means it has it's own area code. I mean, really? Think about this for a second; Guam is on the other side of the international date-line. But you can call it toll-free from most landlines... (the area code is 671, btw). If I called Guam right now, it is about 7:00am on SATURDAY MORNING! That's tomorrow!!! Frankly, I'm a mildly appalled but mostly amused at all of the US's unincorporated territories. It seems very silly.



But I digress.

The real reason I wanted to tell you about Guam has to do with a good friend of mine who just spent her whole summer there. I had never really heard anything about Guam before I was first educated by mi amiga, Eleanor. Guam used to be home to a great diversity of birds. But then, in WWII, the US military introduced the brown treesnake to the island. Now Guam has no birds, but has the highest density of snakes in the world.

Here's a picture of Eleanor holding one of the world's LAST Guam Rails.

The majority of Guam's endemic species are now critically endangered or extinct. So sad.

In attempts to improve the plight of Guam's endemics, officials on the island have concocted a PLAN!

Get some dead mice. Stuff them with Tylenol, tie them to cardboard, add some streamers, and drop them from helicopters!

Oh good. Thank goodness someone came up with that idea. The island is saved!

But really, this might actually be a good idea even though it sounds completely absurd. As it turns out, the brown treesnake can not ingest acetaminophen. It's toxic to them. So, the hope is that these hungry little snakes will eat the dead, pill-stuffed mice and then die. Hopefully.

They're trying out this interesting method of snake-control on some small areas of forest first. If these experiments work, they might start dropping dead mice all over the island. The people of Guam really hate these snakes.

Research Symposium!!!

Whoa! I finally presented my research today! My colorful poster got a lot of attention and I was basically talking and explaining my research for all two hours of the symposium! It was GREAT!

Here's what the final product looked like



And that's what I have been researching for the past six months! Hopefully, I will continue this research in grad school and get my PhD working with the people who discovered wing-sounds in the first place. I can't wait!!!

Random Thought of the Day

I was recently assigned a short essay to write for my Mars Exploration class. The prompt was,

"How many people are in space right now?"

So I Googled it: "how many people are in space right now?"

and got this website:

www.HowManyPeopleAreInSpaceRightNow.com


Yup. That's it.
That was an easy essay.

As a side note, Don't you find it sad that we have been sending people into space for more than 50 years, and yet there are only SIX people in space right now... There has been essentially NO progress in space flight/travel/exploration since the mid-seventies. Does anyone even care about this anymore?

I find it very, very sad.

So, I am sitting here prepping for two different labs focusing on the identification of marine invertebrates and I just had to share some fun information!

Did you know that in some parts of the deep ocean, more than 80% of organisms are bioluminescent?!

That's a crazy high percentage, isn't it?! There's this chica, Edith Widder


who has dedicated her life to studying marine invertebrates of the deep oceans. She invented this brilliant, yet simple method to observe animals of the deep without scaring them off with bright lights and loud engines. With this new method she has discovered tons of new species! Check it out!



This is a video from TED Talks, of course. Once again, gotta love TED.

I just pulled an all-nighter...

Poor life-choice number one for this week: pulling an all-nighter.

I stayed up last night finishing my research poster. Don't worry, it turned out great, it's probably the best research poster you have ever seen. But I didn't go to bed until about 7:30.

Now that I have been up for a full 24 hours without sleep, I just have to wonder...

What would my brain look like on an MRI scan right now?!  I wonder if it's any different than a fully rested brain?!

So I found out!

Dear Internet,
I love you.
Love,
Robert

There was a study conducted in 2007 by Matthew Walker,et al. (The emotional human brain without sleep- a prefontal amygdala disconnect. Current Biology, 17:877-878) that put a whole bunch of well-rested (12) and 35-hour-sleep-deprived individuals (14) into a MRI scanner (not all at the same time, of course!) and showed them images to illicit an emotional response. Then when their brain was responding and showing emotion, the scientists took a picture:


The brain on the left is a normal brain, showing a normal emotional reaction in the amygdala region.

The brain on the right, is a sleep-deprived brain. It is showing an erratic, uncontrolled and over-activated emotional response. This crazy response, as it turns out, closely resembles a much more primitive pattern of activity. The sleep-deprived brain is unable to put emotional experiences into context and cannot produce controlled appropriate responses.

Therefore, sleep-deprived individuals really do turn into....


Zombies! Incapable of appropriate emotional responses to emotional experiences.

Ok, but really, this research suggests that sleep and psychological disorders may be linked. Previous studies have shown that many patients with psychiatric disorders often also suffer from sleep disorders.

So here's the big take-home message: Get plenty of sleep each night, and you really will wake up in a better mood and have a better, less emotionally stressful day! Thanks for the advice, mom! Even though you didn't know it, IT'S SCIENCE!

Now, if we could just work on your fly-catching hypotheses...

Birds Birds Birds Birds Birds Birds Birds Birds Birds Birds Birds

Some days, no matter how hard I try, all I can think about are birds.

This morning I woke up at 5AM to go birding. I spent four hours out and about (or oot and aboot as my marine bio prof would say - which, as a completely off-topic sidenote, can be easily confused with oot in a boot, which is a topic that comes up often in our marine biology conversations, as boats are integral parts of marine bio... Ok, that was a lengthy parenthetical... back to birds!). This particular morning, I brought along my nifty high-speed video camera with 20x optical zoom and had a TON of fun...



I have some really really really great, beautiful, pretty much perfect videos of flight, but I'm saving those to publish. Sorry! If you absolutely HAVE to see these amazing vids before I publish them, you should come to the Student Research Symposium on September 9th on the 2nd floor of Harned! I'll be showing a couple of them there!!! Get excited. 'Cuz I am.
