The smell of love, why space will suck, robots, zombies, and more!

Every week, we round up the best tips that you post in io9's tips forum. This week, we've got a mash-up of smelly couples, the crappiness of space travel, creepy robots, sciencey things, zombie bites, and much more!

If you want to post a tip, just click on the #tips link on our navigation bar, or include the word #tips in any comment, on any post, that you think is a good tip for the people who read and write io9.

Tip: Love the scent of your significant other? You may be able to interpret more from it than you think.

BullfightsOnAcid brings us this tip which is, like most things concerning love, simultaneously awesome and kind of gross:

Close couples can actually smell each other's emotions

Close romantic partners unknowingly smell each other's feelings of happiness, fear and sexual arousal, according to a study presented on May 29 at the Association for Psychological Science annual convention.

So the next time you think you might be pissing your girlfriend off, just get right up in her armpit and sniff away. I assume that's the only way to figure out what's upsetting her.

Tip: Space travel will inevitably suck for a very long time.

Sorry, nerds. ExtensionOfBob brings us the story:

6 Reasons Space Travel Will Always Suck [www.cracked.com]

Wow, that even makes the bleakness of the Discovery One seem like a happy sunny funtimes land.

Tip: Robots are seriously going to take over the world.

I, for one, have a natural distrust of our mechanical (soon-to-be) enemies but that doesn't seem to stop the rest of the world from making more and more lifelike robotic creations. Kris Miranda thinks these two (terrifying) videos are pretty neat and you may well agree. I believe the second one has been on io9 before but, hey, let's take another looksie:

Tip: Science is crazy.

Or maybe that's just my puny liberal arts major brain talking. Anyway, Log1c made me feel incredibly dense with this comment:

Your science lesson for the day.

NASA's Dawn Spacecraft Fires Past Record for Speed Change
Using some fancy Xenon ion propulsion the Dawn spacecraft overtook the Deep Space 1 as the manmade vehicle to go really fast using its own propulsion. (The DS1 uses an ion engine as well). Dawn is currently travelling over 4.3 Km/second (9600 miles/hr) after a constant acceleration of over 620 days. Eventually it will be going nearly 39,000 km/hour (24,000 miles/hour) after a total of 5.5 years of constant thrust.

Also, they say 'thrusting' a lot in the article which makes it a funny read. If you have the mind of a 12 year old. (I giggled a bit)

Quantum weirdness wins again: Entanglement clocks in at 10,000+ times faster than light
Another quantum entanglement article. This one is pretty cool because they were actively trying to measure how fast the photons in each entangled pair were traveling/switching rather than its use as an information transfer method. Also, these entangled photons were linked by a fiber optic cable instead of 'free-space waveguide' (air...). It's a cool article because they talk about the problems with measuring quantum entangled things which seem to act faster than the speed of light would dictate and talk about how it's mostly due to experiment design and our inability to measure things about quantum events.

Tip: It's normal to be concerned about your fellow post-apocalyptic travelers being infected with zombie juice.

I'm not sure if this has been posted before, but:

How to deal with the jerk who's hiding a zombie bite. It's nice to know that I can use my asthma as a cover-up for any potential zombie-ism.
