These are lettuce and pea seeds I put in last week. They are growing in my back yard, in a plastic container that held spinach. Yes, it is cold. And it freezes and sleets and ices up, still. But this is winter gardening and people do it even in colder climates than northern Virginia.

You just wash a plastic container that has a lid, punch some holes in the top and bottom, put in some soil (I use a seeding mix) and sprinkle in seeds. Water, close the container, label it with a permanent marker. Place it outside in a sunny area. Now you have a greenhouse environment for your seeds to grow. I may need to transplant these into a larger container before it gets warm enough to plant in the garden.

I also have some flowers and pampas grass sprouting.

Your seeds really want to grow, even in harsh conditions. Like us, they are animated by the life force.

Related to stuff we’re talking about.

2011 was the ninth-warmest year on record:

The finding continues a trend in which nine of the 10 warmest years in the modern meteorological record have occurred since the year 2000.

Karst topography is found throughout the Driftless area. This is characterized by caves and cave systems, disappearing streams, blind valleys, underground streams, sinkholes, springs, and cold streams.

Disappearing streams and blind valleys. Sounds about right.

So what can this unusual library tell us? First, there is the simple parts list. The most common component was organic material, present in 40 of the 63 particles – exactly what is unclear, but it could be anything from pollen to sloughed-off bits of researcher. Quartz, found in 34 particles, came next, followed by carbonates (17 particles) and gypsum (14). “The minerals blow in,” says Coe. “They come from all over the world.” Other ingredients included air pollutants and fertiliser chemicals.

Anyone counting will also have noticed that there are already more components than particles. That is because most specks of dust are conglomerates, which means they may take an infinite variety of forms, much like snowflakes. The next obvious step was to find out what individual conglomerates looked like, but pinpointing exactly which speck corresponded to which spectrum wasn’t going to be easy. So Coe launched a competition. The first person to capture an electron microscope image of a particle that had already been analysed with infrared light would get to name it. And, if that was not enough, there was a free dinner on offer too. What student could fail to rise to that challenge?

Chicago Screenshots is a (slowly growing) collection of Chicago-centric movie and television stills, presented as architectural and urban landscape photography.

“In 1901 you needed to be under the mistletoe to steal a kiss in public,” said Mr. George. “In 2011, you can do just about anything you want in public and it goes unnoticed.” When asked about the shortage, Mr. George was confident there would be no love lost.

Massachusetts architect Peter Herman spent two years designing a paper cup that eliminates the plastic lid.

The construction is simple: The body and two integrated flaps are composed of a single piece of paper; the body is glued to the circular base. Like similar cups on the market, the paper would be waterproofed, though ideally with cellulose-based plastic, so that it could be composted.
