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.

Violent World Of Raptors Explored
From Science Daily:
ScienceDaily (Nov. 25, 2009) — A journey that started with a box of bird feet carried three Montana State University graduate students into the gruesome world of raptors and led to their findings being published in a prominent journal.
Normally focused on dinosaurs, the students compared the claws and killing methods of four types of raptors and published a paper about their research in the Nov. 25th issue of PLoS ONE, a scientific journal published online by the Public Library of Science. The birds of prey that were studied live in North America and Europe and include eagles and hawks, owls, osprey and falcons.

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.

DOE Announces $620 Million in Smart Grid Project Grants
From Popular Science:
While the Smart Grid we needed years ago is still years away, the Obama administration took a step forward today as Energy Secretary Steven Chu announced $620 million in stimulus awards for 32 Smart Grid demonstration projects benefiting 21 states. A decidedly feel-good video that is nonetheless educational was released along with the announcement and explains (in broad terms at least) what the DOE aims to achieve with its Smart Grid investment. View it after the jump.

Birthplace Of Cosmic Guitar Pinpointed
From New Scientist:
IT'S the biggest guitar in the galaxy. The Guitar pulsar is a stellar corpse that is tearing through interstellar gas and creating a guitar-shaped wake of hot hydrogen (pictured). Its birthplace may now have been found.
Little is known about the origins of such wayward stellar remnants. To hunt for the pulsar's birthplace, Nina Tetzlaff at the University of Jena in Germany and colleagues projected the paths of 140 nearby groups of stars backwards in time over 5 million years.

Lost: Darwin's Missing Notebook
From The Telegraph:
An appeal has been launched to track down one of Charles Darwin's most important notebooks, which was probably stolen in the early 1980s.
English Heritage wants anyone who might know of the whereabouts of Darwin's 'Galapagos notebook' to come forward.
It is launching the appeal today to coincide with the 150th anniversary of the publication of On the Origin of Species.
To mark the anniversary, English Heritage is also publishing online Darwin's 14 other notebooks from his time aboard HMS Beagle between 1831 and 1836.

HIV Infections And Deaths Fall As Drugs Have Impact
Greater access to anti-retroviral drugs has helped cut the death toll from HIV by more than 10% over the past five years, latest figures show.
The World Health Organization and the Joint UN Programme on HIV/Aids (UNAids) say an estimated 33.4 million people worldwide are infected with HIV.
That figure is up from 33 million in 2007 because fewer are dying with HIV.
The latest report also shows there has been a significant drop in the number of new HIV infections.

How The Brain Filters Out Distracting Thoughts To Focus On A Single Bit Of Information
From Science Daily:
Science Daily (Nov. 23, 2009) — The human brain is bombarded with all kinds of information, from the memory of last night's delicious dinner to the instructions from your boss at your morning meeting. But how do you "tune in" to just one thought or idea and ignore all the rest of what is going on around you, until it comes time to think of something else?

Bigger Brains Not Always Smarter
From Live Science:
More brains doesn't necessarily equal more smarts, a new comparison of animal noggins reveals.
Tiny insects could be as intelligent as much bigger animals, despite only having a brain the size of a pinhead, researchers argue in the Nov. 17 issue of the journal Current Biology.
The scientists found that past studies suggest larger animals may need bigger brains simply because there is more to control — for example they need to move bigger muscles and therefore need more and bigger nerves to move them, the authors say. But that may not equate to higher thought.

One-Quarter of World's Population Lacks Electricity
From Scientific American:
Replacing wood and coal with electricity could help reduce poverty and pollution.
Some 130 years since Thomas Edison's breakthrough with artificial light, nearly a quarter of humanity still lacks electricity, a fact officials here want delegates to the upcoming U.N. climate talks to consider.
Vast swaths of the world also have no access to modern fuels like natural gas, kerosene or propane, relying instead on wood or charcoal as principal sources of energy. Switching to energy sources that are more efficient and less detrimental to human health is a prerequisite for raising billions out of poverty as nations promised to do, U.N. officials point out.
