Air Pollution Maps Of The United States
From The Next Big Future:
Map of coal power by state. Note: about of third of the air pollution can go thousands of miles from the plant. There is more impact on air quality and health of those near the plants. Air pollution has been improved in the USA since the 1950s and 1960s. There is still a negative effect. 24,000 coal impacted deaths and a total of 60,000 air pollution impacted deaths out of 2.5 million deaths from any cause. Cigarette smoking and obesity have larger negative effects, which is seen in West Virginia's health statistics. The bad air pollution states are ending up at or near the bottom of state health rankings.

Industrial Thanksgiving: Science Takes Mom’s Recipes to the Assembly-Line
From Wired Science:
Thanksgiving is about eating, and though local, organic food might be what the cool kids are eating, most people are still eating products of the industrial food system.
Whether you’re talking turkey, cranberries or potatoes, industrial-scale processes have been developed to drive down food costs, drive up corporate profits and feed America’s incredible hunger for novel food items.
But most consumers of these manufactured meals have little or no knowledge of the machines and methods used to freeze turkeys, turn potatoes into fake potatoes, and cranberries into TV-dinner cranberry sauce. It’s not always pretty, but food scientists’ epic battle to scale up your mom’s recipes without making them taste nasty is worth examining, if not giving thanks for.

Thanksgiving Day Facts: Pilgrims, Dinner, Parades, More
It may be called Turkey Day, but the U.S. Thanksgiving Day is about more than just the bird. Learn about a holiday myth—the first "real" Thanksgiving wasn't until the 1800s—and how we celebrate Thanksgiving dinner today.
Key to any Thanksgiving Day menu is a fat turkey and cranberry sauce.
Some 250 million turkeys were raised in the U.S. in 2009 for slaughter, according to the U.S. Department of Agriculture's National Agricultural Statistics Service. Those birds were worth about U.S. $4.5 billion.

Chandra Hosts A Carnival Of Space
From the Chandra Blog:
This week, the United States marks the Thanksgiving holiday. For most of us, this means lots of time with family (sometimes too much), friends, and vast amounts of food. It also causes all productivity to cease anywhere close to Thursday and the days that follow. That said, however, science and space never sleep – not even from an overdose of tryptophan. (For those of you who are unfamiliar with this word, it has to do with pseudo-urban legends surrounding the American overconsumption of turkey on this holiday.) Now, off to our spin around the blogs.

Arming The Immune System Against H1N1
From Technology Review:
Researchers are working to treat pandemic flu by recruiting a patient's own immune cells.
Viruses multiply incredibly quickly once they've infected their victim--so fast that antiviral medications such as Tamiflu are only effective if given during the first few days of an infection. After that, the viral load is just too high for a single drug to fight off. But researchers are working on a treatment for the H1N1 virus (or swine flu) that uses a different approach. Rather than disabling the virus with a drug, they're creating a vaccine that can activate and steer a patient's own immune cells to attack the invader.

Shuttle Atlantis Departs From Space Station
From Space.com:
The space shuttle Atlantis cast off from the International Space Station early Wednesday after almost a week linked to deliver vital spare parts.
The shuttle detached from the orbiting laboratory at 4:53 a.m. EST (0953 GMT), and flew in a circle around the station so that astronauts on the orbiter could snap detailed photographs to check on the state of the outpost.
"It's a pretty exciting thing to do, be able to see the station you were living in again now on the farewell," STS-129 commander Charlie Hobaugh said in a preflight interview. "Just having it gives us a new snapshot in time of the condition of the vehicle at that point."

Utility Energy Storage No Longer Just Giant Batteries
From CNET News:
If you need more evidence that energy storage is much more than lithium ion batteries, take a look at the latest smart-grid utility storage projects.
The Department of Energy on Tuesday announced that $620 million in stimulus funding is going to 32 smart-grid programs, which will be coupled with another $1 billion in private money. A total of $770 million from government and industry sources in the next few years will go to energy storage, giving a number of storage technologies a dose of real-world experience.

Organic Wine-Makers Look to Greener Packaging
From Scientific American:
More and more wineries offer organic varieties to lower their eco-footprints. It's no surprise that they're looking at their product packaging's environmental impacts, as well.
With more and more wineries offering organic varieties to lower their eco-footprint, it’s no surprise that they’re looking at the environmental impacts of their packaging as well. The making of conventional glass bottles (and the corks that cap them) uses significant quantities of natural resources and generates considerable pollution. According to the U.S. Environmental Protection Agency, the process of manufacturing glass not only contributes its share of greenhouse gas emissions but also generates nitrogen oxides, sulfur dioxide and tiny particulates that can damage lung tissue when breathed in.
