Dr. Who Sells Computers

Here's a treat -- in 1980, Prime Computer (aka PR1ME Computer if you were totally awesome) hired actors Tom Baker and Lalla Ward (then playing Dr. Who and Romana on the BBC's Dr. Who series) to promote Prime Computers in TV ads. Below is a video compiling all the ads. Dr. Who was a particularly apt early-80's computer salesman, given the series' kitchsy mix of high- and low-tech.

Note the tagline: "Step Into the 80's!"

Are Cigarette Butts the Secret to Better Roads?

A cigarette butt on the pavement is disgusting. A cigarette butt in the pavement, though—well, that's another story. Scientists writing in the journal Construction and Building Materials say butt-studded asphalt could be the wave of the future.

Tobacco companies produce about 6 trillion cigarettes every year, which leads to about 1.3 million tons of butts.

Lead author Abbas Mohajerani is an engineer at RMIT University in Melbourne, Australia. "In Australia alone, people smoke about 25 to 30 billion filtered cigarettes a year and, of these, about 7 billion are littered," he said in a statement.

Butts that end up in a landfill are not much better off. They're slow to decompose, and when they do, they release their nasty chemicals into the soil and water around them.

Mohajerani knows that we're not going to get everyone on Earth to stop smoking. But there may be other things we can do. He and his colleagues at RMIT have begun incorporating cigarette butts into different construction materials.

They started with bricks. And while it may sound like a weird, abstract art project, the addition of cigarette butts actually makes a lot of sense. The very thing that makes cigarettes disposable—their flammability—also can help make better, cheaper bricks. The researchers found that changing a brick's composition to include just 1 percent cigarette waste reduced the amount of energy required to fire that brick by a whopping 58 percent.

The waste-added bricks also were better at insulating than standard bricks—which could reduce a brick building's heating and cooling costs.

For their latest study, the team sealed cigarette butts in bitumen and paraffin wax, then combined them with hot asphalt. The resulting pavement was not only functional but, like the bricks, better for the surrounding environment. The inclusion of the bitumen decreased the pavement's ability to conduct heat, which could help keep already overheated cities cooler.

Most importantly, both the bricks and the asphalt imprisoned the cigarettes' toxic chemicals and prevented them from poisoning their surroundings.

"This research shows that you can create a new construction material while ridding the environment of a huge waste problem," Mohajerani said.

The Most Popular Emojis Around the World

Emojis may be the closest thing we currently have to a universal language. But even between English-speaking countries, emoji-texting habits can vary greatly.

HighSpeedInternet.com recently conducted an international survey on emoji usage and used the data to make the map below.

Of the nine English-speaking countries they studied, all nine chose the basic smiley emoji as their favorite pictograph. The second-place symbols are where interesting trends start to appear: For example, respondents in Jamaica, Trinidad, the UK, and the U.S. are all partial to the teary-eyed laughing emoji. Love is also a popular theme. Texters in Canada like sending one heart, while in New Zealand they prefer two. But not every country is so wholesome: In Ireland, the most popular emoji message behind a smiley face is a double poop.

They also determined that different countries have different interpretations of the same images; while everyone seems to greet that the kissing heart face means "love you," where some countries see an innocuous food image like an eggplant or a peach for exactly what it is, other countries have a less PG-rated view of them. (Learn more about their findings here.)

It should come as no surprise that emojis are loved in the U.S., where residents report including them in over half of all text messages. Besides Trinidad, all other countries included in the survey reported using emojis in less than 25 percent of texts.
