The Kawaii Lizard Lady

I have wanted to save up for a digital drawing tablet for ages now, mainly for the purposes of doing cutesy hand-writing on blog photos. But recently, I've also been really inspired by my favourite artists to learn how to do digital illustration as well.

So, I don't know where this is going, but my blog is where I share my creative pursuits (such as my first ever sewing attempt - and I got better at that, too!) so behold: My first ever illustration, that I did today to try out the tablet.

She is the Kawaii Lizard Lady (idk why either).

If you take a look at my favourite illustrators, you'll see that I'm very into surreal, cartoon-like illustrations of hipster girls with some element of japanese culture thrown into the mix (pop-surrealism is what you would call it, I guess) - so this is basically a direct emulation of that.

Anyway, I'm fairly happy with it for some kind of first-attempt-ever at illustration, because I have never been able to draw, yet I free-handed this lovely lady! I think the ability to "ctrl-Z" any lines that I've drawn wrong, and to copy and paste certain elements (like the eyes and bows), has stopped me from having such a fear of drawing! Still, baby-steps while it still looks like something drawn in paint, haha.

Are there any other digital illustrators out there? I'd love to see your work! (And any tips or learn-how-to-draw sources for someone with literally no knowledge of drawing wouldn't go astray, either).

I hope you're all very well,

Who Stole The Milk Maid's Outfit? + New Human Body Parts

dress - c/o Romwe (way back) | socks - Clear It | blouse - thrifted | shoes - JuJu Shoes

So I'm justifying all my recent clothing purchases by "but it was on my ethical store directory! I should proooobably review it if I haven't already bought stuff from that store!"

The latest item to succumb to this "justification": these Juju Jellies. I thought that they were great (and looked amazing) until I tried to walk the 15 minutes uphill from the train station to my parents house last night whilst wearing them - where my choice of shoes inadvertently turned that short walk into an excruciating 35-minute hobble. This is because while the heel isn't so steep, the slight decline causes my pinkie toe to be wedged into a very uncomfortable position into that last cut-out before the toe-cap of the shoes. I thought my pinkie toenails were going to be black and bruised by the time I got the shoes off. Maybe I just have weird feet, or tiny pinkies, and I'll try to remedy the situation with some kind of soft foam on the insides of my shoes. Because while they're uncomfortable to walk in they're also BEAUTIFUL and I don't want to have to part ways with them! I think that these would probably be more comfortable.

So did you guys know that we're still discovering body parts?? As mad as it sounds, we are still learning about the basic anatomy of the human body, and finding things that we didn't already know existed. This new human body part is called the "anterolateral ligment" and is a ligament in the knee. People have suspected its existence in the past, but it's never been defined or definitively said to exist (meaning, it hasn't been something knee surgeons are taught about) until now.

That's like knowing there is a vague large mushy shape in the chest that beats occasionally, but not knowing that it's a heart (and having chest surgeons argue for years that it doesn't exist). Alright so it's not as important as a heart for life, but allow me this analogy.

I might be popping in here less frequently over the next 2 weeks while I finish off my exams and write up my giant scary research report! Wish me luck!

Buns & Bikes & Biochemistry Basics (part 1)

dress - Bonne Chance Collections | shoes - c/o Yeswalker | bike - Reid Cycles

With this bike, I successfully obtained Hipster level 9000 (I subtracted 1000 points due to my lack of square black-framed glasses - with them I would obtain the status of Ultimate Hipster. Too bad). I've been riding this beautiful thing around everywhere since I got it on Thursday, as you can probably see from the many bruises now adorning my legs (I bruise extraordinarily easily and am also pretty clumsy - not the best combination for bike riding, but I don't care!)

On the weekend, I rode to some fantastic second-hand markets where I also picked up this coat:

Which was a highly inappropriate purchase considering that it was a sweltering 30 degrees, and Sydney summers never require coats, but I couldn't help myself with its sailor-esque collar and cute white buttons.

Now, let's talk genetics!

Genetics and the basics of biochemistry take a long time to wrap your head around. Much of my love of science comes from actually understanding how things work. When you read science stories, you might be like, "yay! researchers discovered the gene for disease x!" and "scientists found that too much protein y makes you develop disease z!", and while that's awesome, without a background in molecular biology, you may also be like "...okay, but what does that actually mean?"

What the heck even are cells, DNA, genes, chromosomes and proteins?

So what I'm going to do in the next few posts is attempt to explain what these terms mean. I'm assuming no prior knowledge of anything biology-related. Today I'm going to explain cells, chromosomes and DNA. Let's go!

Your body is actually composed of units called "cells". Cells are little water-filled sacks that contain useful things needed to sustain life, including DNA. Take a look at your skin. If you could zoom right in on a single cell, using microscopic eyes, you would see something like this:

This cell actually looks like it's not very healthy, as it's been burst open on the left side and all of its contents are spilling out. Also, top-layer skin cells are usually actually dead cells without any DNA in them - skin needs to be tough, so this layer of cells often sacrifice themselves to become a tough outer-layer - but let's ignore that fact for the moment. Imagine that we're looking at skins cells a few layers of skin deep.

Cells make up most of your body - your organs, your bones, your brain - it's all made up of cells. And cells are pretty tiny, around 0.00001 - 0.00005 metres long.

However, in each of your cells - except for your red blood cells - you have 2 metres of a thing called DNA that is wound up really, really tightly. Remember how teeny tiny I just said cells were? So your DNA is wound up REALLY tightly to fit 2 metres of the stuff within every cell.

When DNA is all wound up like this, it's given the name "chromosome". A chromosome is really just a long strand of DNA, that's been wound around on itself a bunch of times. You have 46 chromosomes in each of your cells - 23 of these come from your mother, and 23 from your father. Each time a cell splits into two (which is how your body grows and fixes itself), it copies each of these chromosomes, and gives equally half to each cell it divides into.

DNA has written on it all the biological instructions needed to make you. These biological instructions come in the form of different molecules (molecules are things which are made up from a few conjoined atoms - and we'll get into that later) called "bases". Bases are what DNA is made out of.

In DNA, there are four such bases, and we give each a different letter: A, T, G and C.

The way that these bases are laid out along the DNA provides DNA with a kind of "language" that the cell can read, and from that, make particular things. For example, if your cell's "reader" (called RNA Polymerase) reads the sequence ATGTCGCGGATG, they will say "Oh! Make some blood-clotting factors!" whereas CCAAGTGTGCA will tell your cell to make insulin (okay, so it's a little more complicated than that, and the sequences it reads are a lot longer, but that's the basic idea of DNA!)

Did you know that you can even extract DNA from cells and have a look at it - using household items? I wrote instructions on exactly how to do so a few months ago! Though remember - unless you have microscopic eyes, you're not going to be able to actually see those bases. To even begin to be able to do that, you'd first need an electron scanning microscope. To wrap your head around the teeny size of cells, and the size of something as small as DNA (even though you've got 2 metres of it in each cell, it's very, VERY thin!) check out this website: The Scale of the Universe.

Watermelons, Zebras and Tactile Touchscreens

dress - c/o Oasap | watermelon shirt - DIY | shoes - c/o Chicwish | socks - Thrifted

This is probably the best photo-taking wall I've found since I moved to Sydney last April. One of my favourite things while out and exploring our neighborhood is coming across bizarre public murals such as this one. As for my outfit, after putting on this shirt I decided to just go the whole way and embody a watermelon by pairing it with a red skirt and green socks.

Also, I've been asked to speak at a TEDxWomen event that's happening here in a month's time! I'm pretty crazy nervous about it, but as it is going to be about one of my favourite things - science communication - it would help me immensely if you could let me know what your favourite science post was from my blog. (You can read through all my science posts here). The talk will be posted on the internet sometime in the future, and I'll make sure to include a link to it here when it is (so long as I don't just, you know, get up and drool for 5 minutes.).

This research project (somewhat strangely) being carried out by Disney is awesome: The creation of tactile touchscreens. Disney have been attempting to develop a technology which will allow people to feel the texture and gradients of images behind a touch screen. The screen itself stays perfectly flat, but the illusion of a three-dimensional object is generated by manipulation of the friction between a finger and the screen using electrical impulses.

Twin Buns & Bionic Legs

Dress - c/o Sheinside (sold out) | Socks - c/o Oasap (sold out) | shoes - c/o Yeswalker (sold out)

Needing opinions on these twin buns - yay or nay? I really need a cute, easy hairstyle that I am happy with while my hair is growing out, otherwise I'm going to just cut it short again (it's often too hard to stop myself when it's going through this awkward growth phase).

I suppose this is also a "Halloween" kind of outfit, though I must try to remind myself to wear black lipstick more often, anyway! I think that black lipstick goes really well with red hair. What do you think?

I thought I should do a more uplifting science piece today after my horrible Halloween facts, hehe. So don't worry - if you were scared by my last post, you don't need to skim through this one today.

Last month, the first thought-controlled bionic leg was attached to Zac Vawter, after his left leg needed to be amputated following a motorbike accident. I've talked about mind control and bionic devices before in June, but what happened here was a real advance on that story. When Zac Vawter thinks "I want to move my leg", his brain, doing its normal thing, sends an electric signal from the motor cortex, down the spine, and to the peripheral nerves in his right knee, which are picked up by electrodes in the bionic leg. And he walks.

The fake leg is so clever that Zac is even able to control certain parts of it. Say, if he wants to move his ankle, the "hamstring" mechanics on his fake leg contract, but not the rest of his leg. This allows his to walk basically seamlessly, which hasn't yet been possible in prosthetic limbs. Read more here.

I hope that you're all having a gorgeous day so far,

DIY Floral Pinafore, Zigzag Legs & What's Eating You?

Pinafore - DIY | shirt - c/o Sheinside | tights - c/o Tabbi Socks | shoes - Asos (warning!)

Remember when I showed you all this skirt about a week ago? Well I decided that I was going to turn it into a pinafore. I'm still not sure whether I like it better than the skirt, but I have plenty of fabric left so I can always make another one. I could even make a matching shirt, dress and headband and wear them all together and look like a crazy person who really, really likes floral patterns - I'm not going to do that, but just saying - I have a lot of this fabric left over.

To make this pinafore, follow my instructions for making a circle skirt here, and if you get that far, you can probably figure out how to cut out three rectangles to make into the front of a pinafore and the two straps! (I might put a DIY up here one day as well).

Now, I'm also obligated to do a little review for these zig-zag tights I'm wearing. Kindly sent to me by Tabbi Socks, they are made in Japan (by this factory; I do my reasearch now).

Firstly - oh my god they're cool. They are this gorgeous olive-green colour (I don't think the photos do them justice) and the zig zag pattern is just perfect - subtle but quirky.

Secondly, the material is very different to normal sheer tights - probably has something to do with them being over 50% cotton - because they're extremely sturdy and don't feel like they'll ever rip or get ladders in them. I love tights that last for more than two wears.

Third - they're incredibly comfy. I've been wearing them constantly the last couple of days at uni so that my legs didn't get too cold in the air conditioned buildings!

You can buy a pair here (and make sure you have a look at their other designs while you're at it - how sweet are these ones?)

Here's some horrific science facts for you guys, just because it's halloween. Enjoy :)

You have mites living on your face. They’re called Demodex folliculorum and they look

like this:

Image source

and no matter how much you wash your face, or wax or pluck your hairs, they will STILL BE THERE. Because they can live INSIDE YOUR PORES. But don’t worry, they’re harmless and natural - and just love the taste of your skin. Yum.

If you’re not already feeling uneasy, then picture your bed for a minute. Reading this in bed? Even better. Comfy, crisp clean linen sheets, and... dust mites, most likely. Dust mites that like nothing better than to mate and defecate all over your sheets and inside your mattress. But unless you’ve got asthma or are allergic to them, they won’t trouble you. Still, you might want to wash your sheets once in a while.

Ahh, barnacles. Harmless, passive sea creatures, right? Not if you’re a female rhizocephalan barnacle. Having grown up on a rock, when a male crab passes them by they’ll shoot themselves inside their bellies and inject their own cells. They’ll feed off the the crab’s food, and, when the time is right, explode their eggs out of the crab’s bellies. Not only does this make the crab sterile, but the barnacle also alters the crab’s body and brain chemistry so much that the crab now thinks that it's a female. The eggs attract a male rhizocephalan who fertilizes them, and the brainwashed crab continues to treat the eggs like its own offspring, caring for them and releasing them into the sea when the time is right, to go on an infect a whole new generation of crabs.

If you’re still not feeling squeamish, why don’t you think about the fact that 90% of

the cells in and on your body are not your own? Or even better still - for every single human gene in your body, there are 360 microbial genes. Genetically speaking, that makes you 0.27 % human. Your body plays host to an enourmous number of microbes - bacteria, yeast, viruses... but don’t worry. Most of them won’t do you any harm. In fact, you wouldn’t be here without them. They help us digest our food, they teach our immune systems to spot dangerous invaders and they also make chemicals to fight off bugs that could make us sick.

Let’s talk about anglerfish sex. *Gasp* you say, *sex isn't meant to be scary!* Well, you probably wouldn’t want to be a male anglerfish. When they’re born, male anglerfish don’t have their own digestive systems. So they need to find a female anglerfish very quickly. When they meet, the male anglerfish bites the female, makes a hole in her body and burrows inside. The male then wastes away, becoming nothing more than a lump on the female containing sperm - so when the time is right, her eggs can be fertilised, making another generation full of male anglerfish destined to a life of servitude!

What about the end of the world? One day, other catastrophic astronomical events notwithstanding, our sun is going to die in a spectacular way, taking with it the Earth and the other planets in our solar system. So not only will you die one day, but so will every trace of you, human culture and civilisation over the entire course of human history. While that's pretty macabre, keep in mind that if stars never exploded, or expanded into all-consuming red giants, we never would have existed in the first place.

And maybe there would still be some trace left of human civilization after our sun explodes. Even if humans never manage to explore and colonize other solar systems, we sent the Golden Record into space some 40 years ago and it has recently left the solar system. Maybe, one day, an alien civilization will stumble across it and spare us another thought. Well, think about the fact that someday, the entire universe is going to end. Whether it'll happen with a big freeze, big bounce, big crunch or a big rip, physicists predict that absolutely everything we know (and don't know) will eventually come to an end.

Happy Halloween!
