Japanese teen trend: "Dragon Ball attack" selfies

"Numerous Japanese teens, it seems, are uploading photos of themselves doing the Kamehameha attack from popular manga and anime series Dragon Ball," writes Kotaku's Japan-based correspondent Brian Ashcraft. There's a photo gallery and it's awesome. Brian had an earlier post at Kotaku about the broader trend in Japan of young women staging photos with manga-style martial arts. Below, one such image found on 2ch, Japan's largest bulletin board, with the heading, "Schoolgirls Nowadays lol".

Celebrate "Pi Day" by throwing hot dogs down a hallway

No, that's not a euphemism for anything. Buffon's Needle is an 18th-century experiment in probability mathematics and geometry that can be used as a way to calculate pi through random sampling. This WikiHow posting explains how you can recreate Buffon's Needle at home, by playing with your food. Read the rest

Great Moments in Pedantry: James and the Giant Peach needs moar seagulls

Children's literature is about the wonder of discovering new worlds, the power of imagination, and the all the little triumphs and defeats that make up a life.

It's also an excellent place to find hypothetical questions that test the laws of physics.

For instance, presupposing that one could grow a peach to the size of a house, could one also really sail that peach across an ocean? And then, presupposing that one could harness the power of 501 seagulls, would that number of seagulls be sufficient to carry said peach through the air?

These are the questions posed in "James' Giant Peach Transport Across the Atlantic", a paper published last fall in the Journal of Physics Special Topics. Read the rest

In praise of stupidity

Matthew Bostick praises honest stupidity in the age of Google, Wikipedia and relentless knowitall-dom.

My life path has led me to some exciting revelations and extraordinary experiences. It’s been carved out by indulging in – and being comfortable with – my own stupidity. Because stupidity is not a bad quality in a person, no matter how many people say it is. Peeking at a dictionary, we can define stupid as someone “marked by a lack of intelligence.” To me, that’s a perfectly reasonable attribute. We don’t just become intelligent one day.We’re in pursuit of cleverness. Many of us never get there. But we try.

Bravo! There is no better way to have fun than to be the dumbest guy in the room, when the room is, say, a TED talk. Read the rest

You, too, can be a guinea pig for pot

Sometimes, it's hard to find people interested in playing the role of guinea pig for the sake of science. And, sometimes, that job is not so hard. Like when what you want the guinea pigs to do is get real high. That's a good example.

Pot-based research isn't all fun and games. Given the interest in medical marijuana for cancer patients and people with AIDS, some of the studies require volunteers to, you know, have cancer or AIDS. Others are interested in the sociology — these scientists want to talk to you about your pot use and collect data about how it may or may not have affected your life.

But the mythical opportunity to "get high for science" really does exist, writes Brian Palmer at Slate.

The National Institutes of Health maintains an online database of clinical trials that are in the recruitment process. As of this writing, there are approximately 100 marijuana studies currently enrolling patients. Each listing contains inclusion criteria (the types of people the researchers are looking for) and exclusion criteria (characteristics that will remove otherwise qualified people from contention).

... there are a few trials that might interest someone looking for a free high. Consider the University of Iowa’s “Effects of Inhaled Cannabis on Driving Performance.” Participants will be dosed with varying amounts of alcohol or vaporized cannabis, then placed into a driving simulator to measure their performance. There are some restrictions. You must be a social drinker and marijuana user already, but you can’t have an addiction.

Protein art

Proteins are made up of chains of amino acids, folded and twisted in on themselves to make incredibly complex shapes.

The human brain, it has been said, is kind of a pattern-finding machine — prone to spotting faces on the moon, fat bunnies in the clouds, and Jesus on slices of toast.

When the two meet, you get Protein Art. May K., a Russian-born artist who lives in Germany, takes actual protein structures, sees the other things those structures seem to look an awful lot like, and then draws cartoons based on the resulting apophenia.

For instance, take a look at the protein structure above. After the jump, you can see the picture that May K. saw in its folds. Read the rest

Another rainy day fun project: Hurricane Hackers

Hurricane Hackers is a hashtag on Twitter (i.e., #hurricanehackers) and a crowdsource hub to create tech and social projects related to Hurricane Sandy. Proposed projects include an ad-hoc food and water delivery system for after the storm and live maps that show which businesses in a given area are actually open. You can propose projects or start working on projects other people have proposed. Check out the official Google Doc, or the IRC channel. (Via Shasha Costanza-Chock) Read the rest

Amazing anatomically correct baked goods

I absolutely love cheeky science cooking projects. So the Eat Your Heart Out bakery website makes me sincerely wish that I lived in London.

From white chocolate vertebre stuffed with dark chocolate cream, to cupcakes topped with beautiful red blood cells, to what I think is a cupcake but KNOW is an amazing cutaway of breast anatomy intricately rendered in fondant ... this stuff is seriously amazing.

Consider it a unicorn chaser against grotesque misogyny. Read the rest

Homebrew Nintendo laser zapper is powerful, awesome

"The plan was simple. Take a nostalgic NES "duck hunt" Zapper, and retrofit it with a ridiculously powerful laser."

A project from North Street Labs. In case it's not obvious, this is dangerous, and could lead to death or blindness without safety precautions.

Components: "2.1A input buck driver, 2x 750mAh 35-70c Lipo batteries, M140 445nm diode, G2 lens. homemade custom heat-sink, turn key safety switch."

Learn how to build your own, here. But remember, kids, always wear protective safety goggles. And, wear the right kind for the laser you're working with. [Video Link].

Burning Man on Instagram: photos by sfslim

I cannot get to Burning Man this year because I'm in cancer treatment. It's funny, too, because the experience of going through that has given me a new kind of fondness for the annual playa festivities. The freedom, the wide open spaces, the happiness of mutants.

Following long-time Burner Aaron Muszalski (@sfslim) on Instagram is the next best thing, and I recommend it strongly, whether or not you're going to be in Black Rock City in person. He's a talented photographer, and he captures the whimsy, the art, the beauty of those vast desert expanses with the comfort of one who knows them all intimately. Bonus: you don't have to get any dust up your gullet.

To all out there as I type this, have lots of sex and fire and drugs and candyraving and shirtcocking for me.

"SFSLIM," on Webstagram, or receive his photos via Twitter. Wish Instagram had a searchable web interface.

And if you'd like to watch the live video webcast from Burning Man, you'll find that here on Ustream. Read the rest

What's climate change ruining today?

In Virginia, rising sea levels are threatening Chincoteague Wildlife Refuge's ability to provide free parking near the beach for the summer tourists who provide a major source of income in the region. Here's a hell of a quote: "Zones that used to be parking areas in the 1990s are now underwater." Also threatened: The beach itself. Read more Daily Climate. (Via Brendon Slotterback) Read the rest

What is climate change ruining today?

Chocolate and high school football are being affected by climate change, according to two stories published on the Scientific American website yesterday. In the case of chocolate, the cocoa its made from is grown in several countries in West Africa, a region heavily affected by higher temperatures and extreme weather patterns. By 2020, there will likely be a 1.5 million ton shortage in cocoa production. As for football, the problem is the fact that, across the United States, cool weather season is kicking in later in the year than it used to. That affects football practice. Specifically, schools are increasingly concerned about the health risks of forcing high school students to get really physical, while fully suited and padded, in today's warmer Augusts and Septembers. So I think it's safe to say that climate change hates fun. It's a fun-hater. Read the rest
