Planck’s New Dust Model

Planck’s latest all-sky survey presents a model of the thermal dust emission. This new model provides an estimate of the temperature of dust throughout the sky and an improved estimate of the dust opacity.

The technical paper has a lot of interesting analyses and can be found here.

A New Cast of Characters for Toronto’s Neighborhood Watch Signs

To see more of Andrew’s creative Neighborhood Watch modifications, follow @dcmism on Instagram.

Where some may have seen only an old sign faded after years of sun exposure, Toronto artist Andrew Lamb (@dcmism) saw an opportunity. Since 2012, Andrew has treated his hometown’s weathered Neighborhood Watch signs as a blank canvas, adorning them with whimsical figures from pop culture.

"My work tends to deal with altering urban infrastructure in a playful manner," explains Andrew. In this case, it’s about repurposing municipal infrastructure to "invoke nostalgic happy memories" with the help of characters as diverse as Zelda, Bruce Lee and the Planeteers.

What are the keys to success when modifying a sign? “Use a laser printer, not an inkjet,” says Andrew, “and don’t fall off your ladder.”
