Dungeness crab and toxic algae

By Tina - November 12, 2015

I wanted to make a crab cake casserole for Thanksgiving this year, but because of the current toxic algae situation along the California coast, it doesn't look like the crab cakes will happen. Bummer.

The toxic algal bloom (brought on by warm El Nino waters) has caused the commercial crab season to be postponed until further notice (that super sucks for the fishermen). The harmful algal bloom (HAB) is created by the planktonic diatom Psudeoom-nitzchia. These guys are not good because they produce the neuotoxin, domoic acid (DOM), which is responsible for a neurological disorder called amnesic shellfish poisoning (ASP).

DOM ACTION
There are a couple of mechanisms attributed as mediators for the effects of domoic acid (DOM). The mech through glutamate receptors is the biggie for excitatory neurotransmission.

Glutamate is a excitatory neurotransmitter in the brain. Kainic acid (KA) is an excitatory amino acid (EAA) analogue of glutamate that is very structurally similar to DOM. Meaning that DOM can bind to glutamate receptors (GluRs, responsible for memory processing) to act as a potent excitatory neurotransmitter and induce neurotoxic effects.

So a couple of things are going on. DOM activates the ionotropic GluRs (iGluRs). DOM also activates the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid/KA receptor (AMPA/KA-R). AMPA/KA-R causes increased levels of intracellular calcium²⁺ions. More calcium ions releases more glutamate. Extra glutamate activates the N-methyl-D-aspartic acid receptor (NMDA-R). All these excess things are bad and can cause apoptotic and necrotic neuronal cell death....so yea. No crab.

Energy: A Beginner's Guide book review

By Tina - October 22, 2015

I wanted to read another book on my Kindle (I got it on Prime Day and I love it) and Mark Zuckerberg told me to read this. Okay I will!

The book (author Smil) opens with a bunch of definitions from notable old people for the word energy and goes straightaway into a very broad and kind of random history lesson of sorts of past discoveries pertaining to anything energy related. The chapter ends with some lively energy units discussion.

Then right after Smil dives into a bunch more energy topics, this time about sun rays and electromagnetic radiation knowledge and earth science and volcanoes and plant facts. Smil spouts some old civilization stuff knowledge about horses and cows and why you should choose one over the other back in the day (cows are better 'cause they eat and digest stringy veggies and he randomly just started calling them ruminants out of the blue like I know what those are... well they're basically cows... just mammals that have digestive powers).

And then it's coal talk. And turbine schematics. And big wars. And a crazy amount of other things like eating and trains and economics. And then the book is over.

There is very little talk about the future of energy, which I thought would have been the most important topic to cover.The book covered a bit about energy sharing with a little conclusion for the tomorrow.

Anyway it's a very fast read (kinda felt like reading Sparknotes for textbooks). A number of topics in the book happened to be review since I took STEM classes at school. I doubt this book would be an easy read if you hadn't. There's just too much information going all at once and at times the writer sounds a little snooty.

But overall it's ok. I wouldn't recommend it to a friend. This book is pretty much a textbook. But if you are a trivia buff, this Beginner's Guide works great. However if you're more interested about what's happening now in terms of energy and the history and general science of it isn't super important, then energy is no good. I ended up a little disappointed. The book, being a Mark Zuckerberg recommendation, I thought would leave more of an impact or something after reading.

Part 2: Making the Netflix cat game

By Tina - October 15, 2015

^^^^^^^^ I have for you the intro of my Netflix Cat game. Looks cute right?

And the game code writing is going ... it's hopefully going somewhere. There are major debugging problems that I have to deal with. But here is what it looks like so far. I'm sure a lot of stuff will change by the time the game is ready.

When you open up the game, you should see a couple JButtons across the top (or bottom, haven't decided where yet). I'm thinking about getting rid of the INTRO button and combining it with the HELP page

This is the HELP page, I am going to change the whole look of it. But this page is simple enough. It's just one button to go back to the MAIN MENU and a background image with instructions. If I combine the INTRO with the HELP, then I'll need to figure out a way to embed the above video I showed you here.

This is the actual game. Pizza, computers, pants, and sheep fall off the screen. For some reason.... the Netflix Cat is not appearing here!!!!!! There are a lot of problems on this page....

Most of the coding I got from this tutorial with lots of tweaks.

BIG PROBLEMS
-I have no idea where Netflix Cat went. And he is SUPER important so I'll need to fix that.
-When Netflix Cat (NC) touches the sheep, NC will turn into Sparkle Cat (SC) and will get 10 seconds of immunity meaning that whatever SC touches will just turn into major big points. I'm having trouble introducing those 10 seconds into the game writing. Also since NC isn't even in the game for some reason, I dunno if the collision detection between the cat and the falling objects is working. (Meaning that I also don't know if the points and life counter on the top right of the game is working too.) AND I dunno if NC/SC moving left and right is working properly too.
-I want to control the rate of occurrence of the objects falling down. Right now all the objects are randomly appearing along the top with random x positions. But some items should be more exclusive (like the sheep and the PC). I also want to give the sheep and PC parabolic falling down trajectories to make it even harder to get it.
-My boolean GameOver is set to false in the beginning of the game. And there is a checker section in my code where the game checks the life counter and if it is <0 then GameOver == true. But something is wrong with the section and all I get are error messages. :(((((((((

EXTRA STUFF
-I haven't added music yet to the game, of course I want to!!!!!!
-Everything needs to be prettier. I'll probably change all the background images and beautify the JButtons.
-I really want to add a cut scene once the game is over. But the internet says that it's hard to do and I couldn't find good examples on how to do it. I thought it would be easy. Like import some media package or something and just have a calling function to get a cut scene once the game is over, but I haven't found anything like that.

The common cold and why old people insist you wear extra layers in bad weather

By Tina - October 14, 2015

The body reacts and acclimates to the cold in a number of ways. Our bodies shiver and our teeth chatter. Goosebumps form. All this is done by the little almond in our brains (the hypothalamus- responsible for thermoregulation) to make sure that we keep warm when the weather outside is frightful. Now as the temperature outside gets cooler, the old people in your family are probably telling you to bundle up as a preemptive measure against "getting sick" because of the chilly weather outside.
Well is it true?
The idea that the temperature can make a person more susceptible to getting a cold has always been regarded as an old wives' tale that isn't true and is just told to scare the children. What happens instead of the cold giving you a cold is that people generally stay indoors when the weather outside is bad. They stay inside with recycled air and cough on each other. It's a people behavior thing.
So it's not true?
But actually being lazy and staying inside (and coughing on everybody) might not be the only reason why people get colds more often during chilly weather time. Rhinovirus (aka RV, the germs that cause the common cold) strains replicate way better in colder temperatures. Why?
Researchers at Yale first started out by modifying a strain of the rhinovirus to infect mice ('cause the people rhinovirus doesn't infect rodents). Then they used these strains to infect airway epithelial cells of mice and compared the transcriptional response of the cells at 33 and 37 degrees Celsius. Incubating the cells at a lower temperature showed that the antiviral defense response was not as strong when compared to incubation at a higher temperature. How? Well, the results indicate that during rhinovirus replication, higher temperatures reveal more RLR ligand accumulation (RIG-I-Like receptors that detect viral RNA species by triggering interferon response for antiviral response) which leads to stronger antiviral gene expression... meaning that there is a possible temperature dependence of common cold sickness and you should wear a sweater and not breathe in cold air.
