What's the next best thing to being an official scientist? Being a non-official one. A new website called Science for Citizens helps you find the science experiment of your dreams, hook up with the scientists involved, and actually take part in the experiment itself. Here are some examples of what you can do:
PopSci has compiled an amazing list of 30 college labs that would tempt anybody to re-enroll. If you know any high school juniors or prospective grad students, pass this along. They just might reconsider their initial choices.
The Department of Biological Sciences at the University of Alberta brings you this flash animated video tutorial specifically relevant to your student laboratory courses, specifically microbiology. If you're a student at any school of biology, this information will be helpful for learning how to make a wet mount.

This video tutorial will show you the steps on how to dissect a frog. First, you'll have to get a frog, then you'll have to make sure it's dead, then perhaps wash it off. Then just take a look at the external anatomy of the amphibian before slicing it open. To slice, you'll need dissection forceps or tweezers and the dissection scissors. From then on, you'll be knee deep in frog anatomy. Tons of internal organs for you to learn from. So, watch this science video for learning about the anatomy...
His name is Don Pettit, but I like to call him Space MacGyver. He's well known for his paper clip fixes and ingenious coffee invention in zero gravity, and we've all seen the NASA astronaut in his Saturday Morning Science videos during his first stay on the International Space Station. And now he's back on the ISS with a brand new physics-related show... Science Off the Sphere.
This video comes straight from the Laboratory for Chocolate Science at MIT. Truffles are delicious, versatile candies that can be flavored in a variety of ways. This recipe shows you how to take tea extract and make tea infused chocolate truffles. Make tea infused chocolate truffles.
The Writers at io9.com have been running through a fantastic series of blog posts, in which they're teaching their readers about the history of great 80s sci-fi and fantasy. Because so much of this is right up my alley, I though I'd aggregate their aggregations, so to speak, and write a little retrospective of my own.
Sometimes science looks like magic and that's exactly what Ryan Oakes is going to demonstrate with this cool trick. You will need pepper, bowl of water and liquid soap. Sometimes we use materials that require adult supervision... like scissors, so make sure you have friends and family around whenever you do magic tricks.
Check out this kitchen table science experiment on how to make electricity from copper, zinc and water. You can make your own battery to power a small LED light from just nails, copper wire and water.
Kent Chemistry offers up some of the most exciting chemistry and general science experiments from their lab. Here Mr. Kent illustrates the process of creating fire with dry ice. How does freezing and flame mix? Watch now to see the amazing chemical reaction!
In this video tutorial, Creative Cow leader Aharon Rabinowitz returns to one of his earliest tutorials, "Creating TV Look," and shows how it can be used to create the look of a Hologram as seen in science fiction movies. Create a sci-fi hologram look in After Effects CS3.
I'm sure you've heard that binging on turkey will make you sleepy, and there's a reason for that. Turkey contains tryptophan, which some believe is the go-to amino acid for increasing serotonin (a calming neurotransmitter) and/or melatonin (a sleep inducing hormone) in your brain. Some say old wives tale, some say science, but clinical research has shown mixed results in regard to its effectiveness as a sleep aid.
It's tough to figure out what a mummy would have looked like when he was alive; soft tissue of a human body decays, even in ice. But, Dutch brothers Adrie and Alfons Kennis took the challenge. Using techniques that belong to both science and art, they managed to reconstruct the face and body of Otzi the Iceman, a mummy who was found in the Italian Alps in 1991.
How about a laser? One that is strong enough to nudge debris out of earth orbit. That's what NASA contractor James Mason wants to do, and his lab simulations suggest that the idea is possible. Mason wants to use a 5kW ground-based laser and a ground-based 1.5 meter telescope to spot potentially hazardous space waste and shove it off, by about 200 meters per day of lasering. It's kind-of like air traffic control for near earth orbit.
The busier you get, the more stuff you forget, and navigating that mental clutter can be worse than steering through an asteroid field. Luckily, lots of intrepid galactic heroes have faced faulty memories, and created some handy techniques for remembering.
For some, adrenaline beats out every time. Though I've seen countless videos of base jumping, the sport never ceases to amaze. The video below, Last Walk Around Mirror Lake – Boom Bip (Boards of Canada Remix), is no exception to the rule. Shot in Norway, FroschYankee's footage is nothing short of stunning. *For more info, check out Adrenaline Rush (The Science of Risk), the film which this clip was featured in.
There are dozens of arguments on the table for reducing our dependance on oil to help the environment, but one cause of pollution that isn't as popular to hate is our domesticated bovine.
The provenance of this Sci Fi Airshow is unquestionable. With decades of experience interpreting science fiction from a written to a visual medium, Bill George is the perfect tour guide for this fantastical, photoshopped exhibit. Assembling the collective imagination of multiple authors into one Airshow is a rare treat.
Where would we be without science? Not everybody's always fresh as a daisy; try Odegon Technologies' iron-on "Odour Tags". When attached to clothing, the patches capture your odoriferous molecules in a carbon mesh. Somehow the patches don't come off in the wash and run about 18 bucks for a pack of six.
Tetherd Cow Ahead posts an interesting science experiment. All you really need is a little bit of iron powder and a magnet, and you can unveil the info behind the magstripe on a credit card.
To make applesauce, you start by peeling some apples and then cut them up and put them into a bowl. Add some cinnamon and water to the cut up apples. Use a potato masher and mash up the apples and mix the ingredients all together. Mashing up the apples is hard, so you have to have perseverance. Once you've mashed them up, pour them into a pot and heat them up on the stove. The heat will change the apples, making them very soft. After you've heated them and they have softened up, pour them bac...
In this video tutorial, viewers learn how to evaluate texture by going on a texture hunt. You will need to do this task in a group. Begin by going around the room and finding a texture that you like. Touch all kinds of things to feel the texture. When you found your texture, bring it back to the group and evaluate it. You will compare and contrast how the object feels. The texture of the objects will vary. They can be smooth, rough, hard, soft , sharp or have any other kind of feel. This vide...
Gather all Mad Scientists. Science doesn't have to be all about hitting the books and memorizing formulas. Sometimes it's closer to Frankenstein or Dr.Jekyll than you can imagine. It's time to turn tomatoes into glow in the dark orbs.

Despite all the recently transpired web hysteria regarding a mysterious NASA press release, the organization has NOT discovered new life on another planet. However, the latest information does indicate that scientists have discovered a new life form on planet Earth.
Relax PETA, it's not as evil as it looks (although those neural electrode implants do look painful).
