Grad School on a Budget

(by scicurious) Apr 25 2013

Grad school in science* is a stressful time. You've got lots of pressure to produce, to do well in classes, to work more hours, to get more done, to learn faster, to teach, to volunteer.

And you're doing it all on, sometimes, less than $25,000 a year**. So on to all of that stress, you have to add more, the fact that you've got to live on that. For many people, this seems like a lot, but if you've got a family? Or other dependents? Not so much. Not only that, even people who DON'T have dependents can have a rough time. Many new grad students have never worked in the "real world". They have no idea how to manage money because they've never really made much, and have usually depended on parents or other caregivers. It's a very, very fortunate position. But it also means that a lot of grad students start grad school with NO idea of how to manage their finances.

And this can mean DEBT. In my time, I've seen grad students buy houses, new cars, more new cars, take super nice trips, wear really nice clothes, get really nice phones, eat out every day, sometimes all of these in combination. Some people can get away with it. A lot of people can't. I've seen people rack up a LOT of debt.

I myself was lucky. I got out with no debt at all, and even managed to save a little. This involved a LOT of frugal living (Costco and Aldi are your friends, and roommates are not a bad thing at all! Thrift stores can have some very nice dress clothes. Also, you'd be stunned by how long you can just keep pouring oil into your car to make it keep running before it just up and dies), but it also involved a lot of luck. Not everyone is lucky. And not everyone has the freedom to make the choices I made. I lived in a cheap area where rentals weren't horrid, so I saved a lot of money there. Food was cheap where I lived. I didn't need major surgery or anything, and neither did my cat. I only had one car die. I got out of grad school before my funding ran out. I had parents that could help me. I was able to use other talents to pull in a little extra income. I was REALLY lucky.

Grad schools know it's not easy. They know that many grad students needs to get used to living on a budget. And quickly. And so there are programs where they tell you things like "pack your lunch! Brew your own coffee! Buy only used cars!" ...like we aren't already doing these things. It can help a little, but most of the time we are left to follow our own instincts.

And so this is why I am VERY glad that Southern Fried Science is doing a series on finances for grad students! There are already a couple of really great posts up on getting a stipend, what to expect from your stipend, and how to build credit. If you're a grad student just starting out, I can't recommend them enough. Read them, take them to heart. And pack your lunch and brew your own coffee most days. Cause, you know, practicality. :)

So head over and check it out! I eagerly await more installments!

*I'm applying this post only to people in science, or in other fields which get a stipend and have tuition paid. In the humanities, you usually get no stipends at ALL and have to pay full tuition. They have it WAY WORSE.

**That's roughly what I made in grad school, lo these, um, three years ago.

Eating your Sleeplessness

(by scicurious) Apr 24 2013

It's late. I've got a lot on my plate. A lot to do. And most of us do. So here I am, burning the midnight oil along with many of my neighbors. I usually count myself lucky to get 7 hours a night, and I AM lucky. For many parents or other caregivers, for example, 7 hours is unheard-of luxury.

But I am tired. And I'm snacking. Because, well. I'm up late and...and it's LATE. And if I don't eat, well I'll probably just fall over right now.

I'd like to think that my staying up late and my late night snacking are a once in a while thing...but really, it's almost every day.

Is it just me? Probably not. Most of us don't get enough sleep, and those who don't sleep? Snack. But why? And what does this mean for issues like obesity?

Experimental Biology 2013!

(by scicurious) Apr 23 2013

Sadly, Sci is NOT joining in the fun at the 2013 Experimental Biology meeting. :(   I really wish that I could have gone this year, but sadly, it's not possible, and I'm going to be one of those horrible deadbeats with an empty posterboard.

But there are others at Experimental Biology, and they are blogging and tweeting up a storm! Make sure to check out @katiesci, who is blogging on behalf of the American Society of Pharmacology and Experimental Therapeutics! She's already got a post or two up on experiencing Boston this week from a science perspective, on careers in science, and on cognitive flexibility! Also make sure you drop by and read David Despain, who is writing for the American Society for Nutrition, and already has a great post up on carotenoids. And don't miss Biochembelle, who is blogging on behalf of the American Society for Biochemistry and Molecular Biology, and has a great post up on the different ways to be an advocate for science, many of which are much easier than you think!

 

So even if, like me, you can't be AT Experimental Biology this year, you can experience it virtually! Follow the blogging and follow along on Twitter, to catch all the latest science!

Friday Weird Science: Real Men Wear Kilts

(by scicurious) Apr 19 2013

I have to say I've always expected it. Wearing kilts...well it takes strength. Confidence. It takes cojones.

connery-1-th
(Also, it takes SUAVITY)

And who knows, it might be the smart thing to do! Forget easy access, forget the free swing of balls on the breeze...could wearing a kilt be best for your SPERM?

Kompanje, EJO. "‘Real men wear kilts’. The anecdotal
evidence that wearing a Scottish kilt has
influence on reproductive potential: how
much is true?" Scottish Medical Journal, 2013.

Today's post comes to you via the incredible Marc Abrahams of the Ignobels. No word on whether this finding will make him wear more kilts.

Book Review: Gulp: Adventures on the Alimentary Canal

(by scicurious) Apr 17 2013

Did you know that hydrogen sulfide, molecule for molecule, is as lethal as cyanide? The only difference is, one of them's in your farts (at far too low of a concentration to harm you, except psychologically).

Did you ever wonder if you could eat (or do drugs) with your butt?

Did you ever wonder what cat food tastes like? And why that should matter to humans? And why dogs (and rats, and others) eat their own poop?

And have you ever thought, really THOUGHT, about your own saliva?

I bet you're thinking about it now.

It's weird, isn't it.

But no saliva, no rectal storage, and no potentially lethal levels of hydrogen sulfide will stop the intrepid Mary Roach, as she embarks upon her latest book, Gulp: Adventures on the Alimentary Canal.

Running and Hypothermia

(by scicurious) Apr 16 2013

I was truly devastated by the news from the Boston Marathon yesterday. This kind of senseless violence perpetrated at what has always been such a positive, peaceful, joyful gathering is just too horrible to describe. Scientific American is covering many aspects of this kind of event, from the wonderful behavior of fellow runners (acting against what psychology tells us), to the value of social media during the crisis. I have a post on why so many of the runners began to show signs of hypothermia after being diverted off the racecourse, and how runners and Bostonians helped each other. And today, I'm Running for Boston, and I hope you will run, walk, or otherwise locomote for Boston, too.

Friday Weird Science: The big deal on penis size

(by scicurious) Apr 12 2013

Sigh. The penis story is now 5 days old, and I'm only just now getting to it. Sci is sad and behind the times, but that's because I don't get the awesome press releases that so many journalists are heir to. The joys of academia, I'm the last to hear about the penis study!

The coverage was so...BIG...that Knight Science Journalism Tracker has a whole pile of links. Science News, NBC (complete with the quote of the day "The human male possesses the Italian designer faucet of penises"), National Geographic. Gawker.

So after all this coverage, I went eagerly to read the paper. I mean, this must be a big deal, right?

But really...I'm not sure why all the penis coverage. I admit it's tough to give up a penis in PNAS joke, but I'm not sure what makes this study...so meaty, shall we say. I think what they did is fine and well controlled, met all the standards of scientific rigidity, but I'm not sure they...went all the way. The conclusions were, well, kind of expected, and a little limp.

You see where I'm going here.

Salt: From "mmm" to "eww"

(by scicurious) Apr 10 2013

I love salt. It's just delicious. I wrote this post while noshing on deliciously salty popcorn, after a dinner which I put salt on. I crave salt so much that my parents used to joke about getting me a salt lick.

And I'm not alone. Sodium is an incredibly important part of life, which means it's also an important part of what we eat. To make sure we get enough salt, animals have evolved salt-sensing systems, and low levels (below 100 mM of NaCl) of salt are very attractive.

deer-at-salt-lick
(A deer at a "salt lick" which is actually a mineral lick made up of various salts and minerals. Yum)

But there IS such a thing as too much salt. High levels of salt (>300 mM NaCl) are really aversive (from personal experience, I wonder if Carrabba's restaurant has concentrations of salt in their food over 300 mM). Most animals will quickly turn up their noses at a high salt concentration.

You probably know that you have classes of receptors on your tongue for taste (though they are not clustered into areas of your mouth, like front for sweetness, as previously thought). You have sweet, umami (savory), bitter, sour, and salt. In most animals, sweet and umami are always attractive, while bitter and sour are nasty (except where we have overcome the aversion to enjoy things like coffee and beer). Salt, though, is the only one that goes two ways, with low levels being attractive and high levels being aversive.

Now we know how low salt works. The salt receptors that are currently known are good for detecting low salt. But high salt, that's more difficult. First of all, our aversion to high salt concentrations is not very selective. While low salt detection is limited to good old NaCl, high salt detection is non-specific, working for many salts including NaCl, but others as well (like KCl).

Not only that, but if you block the low salt pathway (you can block the sodium channels involved by using a diuretic), the high salt pathway still functions, which means that there are other receptors involved. But what other receptors?

Well, it turns out that high salt is not just...salty. It's BITTER. and SOUR. Or at least, your receptors think so.
