Burkina Faso native Assami Semde was delivering two pizzas in the Harlem area of New York City when he was accosted by two hooded teenagers. One drew a gun and demanded the pizzas. Semde put the pizzas down and punched the gunman, who ran off. Then he grabbed and held the other man until police arrived. Then he finished delivering the pizzas, still hot, before he went to file a police report.

Semde's boss, Frank Grecco -- a retired NYPD detective with 22 years on the force -- called the teen "very courageous" but added, "I told him, 'Next time, leave the pizza!'

"He now realizes that he may have done something a little bit crazy," said Grecco, who owns the East Harlem Famous Famiglia.

Semde agreed.

"It's crazy. I think it's better not to fight," he said.

Wired takes a look at new technologies for delivering nutrients to our bodies, from meat grown in laboratories instead of farms to ocean-grown crops. And there's a possibility we won't even need food in the future! Scientist Robert Freitas imagines humans ingesting nanorobots that could supply each cell with energy as it is needed.

This would only replace food’s caloric aspect, so we’d still need to take vitamin and nutritional supplements in order to provide the body with new matter as cells die off, according to Patrick Tucker, director of communications for the World Future Society. Still, there’s a certain cold comfort in knowing that if worse comes to worst, nanotechnology might give us a food pill that, taken every 10 years or so, would power our bodies if the planet loses the ability to do so — or if we’re forced to leave the planet, as Stephen Hawking suggests.

If history had swung in a slightly different direction, we may have spent fourth grade memorizing the capitals of Sylvania, Deseret, Texlahoma, and Forgottonia. I would be living in Transylvania!

American pioneer Daniel Boone also had a thing for the "sylvania" suffix. If he'd had his way, Kentucky would have been called Transylvania and we'd be placing bets on horses at the Transylvania Derby. Boone hoped to call the colony's capital Boonesborough, but much to the explorer's chagrin, North Carolina and Virginia voted against Transylvania's existence.

This picture shows what hydrogen atoms might look like if we could see them.

The chart above shows the appearance of a single hydrogen atom in a few of its lowest excited states. In each of those states, the electron is found in a different orbital, some of which have unfamiliar shapes. But even the term "shape" is a little funny for something that you can't hold in your hand. These are actually probability density plots, which show the likelihood of observing the electron in any one position at a given time-- and more correctly, 2D projections of 3D probability densities.

So even the humble hydrogen atom can be a bit complex. Fortunately, we have advanced technology that can help us cut though the quantum mechanical haze: Cookies!

What we can see (and taste) are cookies made to resemble the shapes of the hydrogen atoms in the chart. The folks at Evil Mad Scientist Laboratories made these cookies and will show you how you can make them, too! Link

Every Easter in Stratford, Ontario you can see the swans returning to the Avon River in style. They are escorted from their winter quarters in a fenced area to the water by a parade of bagpipers! The Stratford Police Services pipe band wore kilts and marched to the river while playing music. The swans waddled behind. Link -via Arbroath

In 1931, a schoolboy wrote a fan letter to his favorite author, Edgar Rice Burroughs. It said, in part:

I am a fourteen year old boy and am a low Junior in High School. Today at school our teacher was discussing "good literature." I asked if Edgar Rice Burroughs was all right for a book report. I knew she'd say "no" (teachers always do) but I didn't expect her to lecture to the class for the whole period about how terrible your books were!

The author of the Tarzan novels wrote back, in part:

My stories will do you no harm. If they have helped to inculcate in you a love of books, they have done you much good. No fiction is worth reading except for entertainment. If it entertains and is clean, it is good literature, or its kind. If it forms the habit of reading, in people who might not read otherwise, it is the best literature.

Which explains why I bought the Twilight books for my youngest daughter. The 14-year-old boy who wrote the letter was Forrest J. Ackerman, {wiki} who grew up to coin the term "sci-fi". Ackerman was a film producer, actor, and the editor of the magazine Famous Monsters of Filmland, and made a name as the biggest science fiction fan ever. Read both letters in full at Letters of Note.

While most people look for the cheapest airfares, Rob Cockerham sought out the most expensive fares from several different airlines. Unsurprisingly, the priciest tickets were either last-minute bookings or scheduled near Christmas. Adding a carbon offset didn't add much, relative to the astronomical ticket prices you could book. The highest fare came from British Airways, but that doesn't mean they are the most expensive airline overall. Link

Doyle Geddes, a teacher at Sky View High School in Smithfield, Utah, led 150 students through the construction of the world's largest recreation of Van Gogh's masterpiece Starry Night. The finished product was 72 feet by 90 feet on the gym floor, and an inch deep in breakfast cereal! A Malt-O-Meal factory donated two tons of Tootie Fruities, Cocoa Dyno-Bites and Frosted Mini Spooners for the project.

“To the best of our knowledge it is the largest re-creation of a Van Gogh work of art in any medium,” he said. The re-creation – made with blue, purple, red, green, yellow and brown cereals – was displayed in a gym at Sky View.

As he looked at the completed project Saturday, Geddes said, “I think it’s better than we even expected or dreamed that it could be.” He thinks Van Gogh would be happy with the re-creation, too.

The work was displayed to the public for four hours on Saturday, then the cereal was collected and given to a farmer to feed his pigs. The Herald Journal details the process of making the recreation. http://news.hjnews.com/news/education/article_c363e3de-3fa0-11df-a496-001cc4c03286.html to story. Link to time-lapse video.

With livestock farmers on both sides of the family, I thought all manure was eco-friendly up to a point. But domesticated pigs have excess phosphorus in both their urine and feces, which does awful things to the water supply and organisms living in the water. Now researchers in Canada have developed a genetically-altered "Enviropig" that produces plenty of the enzyme a pig needs to process phosphorus.

To fix this problem, the scientists tinkered with the swine’s genes to make the pig produce its own phytase in its salivary glands. When the cereal grains are consumed, they mix with the phytase in the saliva, and throughout the pig’s digestive tract the enzyme works to break down the phosphorous in the food. With more phosphorus retained within the body, the amount excreted in waste is reduced by almost 65 percent, say researchers.

The researchers who created the Enviropig say it’s not just eco-friendly, but it also cut farmers’ feed-supplement costs. If the pigs eventually become common, they could also help U.S. farmers comply with “zero discharge” rules that forbid pork producers from releasing nitrogen or phosphorus runoff.

The pigs are now being raised on test farms, and won't be available to consumers anywhere for a few years. Link

Spring means baseball time! To celebrate, try your hand and eye at today's Lunchtime Quiz at mental_floss. You'll be given one letter from a Major League Baseball team logo, and you tell us what team it is (don't include the city). Some may be past versions of the logo, and some may be tilted, just to make things interesting. I got two right out of 13, ha! I'm sure some of the answers I put in were football teams. Surely, you will do better. Link
