NASA Shuttle Discovery Set To Buzz Washington, DC
NASA Shuttle Discovery Set To Buzz Washington, DC:
coondoggie writes "Barring bad weather, NASA said the space shuttle Discovery mounted atop the space agency's 747 Shuttle Carrier Aircraft will make a series of low passes — 1,500 ft. — around parts of Washington DC on April 17 between 10-11 am eastern daylight time." Discovery will be on its way to the Smithsonian from Florida; this is a rare chance in the post-shuttle era for people to still see a shuttle in flight; I'm planning a marathon drive to reach the parking lot at the Steven F. Udvar-Hazy Center for what NASA's calling Shuttle Fly-In Day, in hopes of catching a glimpse.

Frequent dental X-rays linked to most common brain tumor
Frequent dental X-rays linked to most common brain tumor: People who received frequent dental x-rays in the past have an increased risk of developing the most commonly diagnosed primary brain tumor in the United States. Ionizing radiation is the primary environmental risk factor for developing meningioma, which is the most frequently diagnosed primary brain tumor in the United States. Dental x-rays are the most common artificial source of exposure to ionizing radiation for individuals living in the United States.
Born nice? Peoples' niceness may reside in their genes, study finds
Born nice? Peoples' niceness may reside in their genes, study finds: It turns out that the milk of human kindness is evoked by something besides mom's good example. Research by psychologists has found that at least part of the reason some people are kind and generous is that their genes nudge them toward it.
Could starving the heart make it resistant to damage?
Could starving the heart make it resistant to damage?: Heart cells starved of nutrients are less likely to be damaged during periods of decreased blood flow and sudden influxes of blood, known as ischemia and reperfusion, and are also less likely to get out of synch with their cellular neighbors, the damaging phenomenon called arrhythmia.
Fish thriving around wind farms
Fish thriving around wind farms: The first Danish study into how one of the worlds largest wind farms affects marine life is now completed. It shows that the wind turbines and the fish live quite happily together. Indeed some species of fish have actually increased in number.

Antioxidant may disrupt Alzheimer's disease process
Antioxidant may disrupt Alzheimer's disease process: Alzheimer's disease (AD) is now the sixth leading cause of death among Americans, affecting nearly 1 in 8 people over the age of 65. There is currently no treatment that alters the course of this disease. However, an increasing amount of evidence suggests that changes in the way the body handles iron and other metals like copper and zinc may start years before the onset of AD symptoms. A new study shows that reducing iron levels in blood plasma may protect the brain from changes related to AD.
Brain-injury data used to map intelligence in the brain
Brain-injury data used to map intelligence in the brain: Scientists report that they have mapped the physical architecture of intelligence in the brain. This is one of the largest and most comprehensive analyses so far of the brain structures vital to general intelligence and to specific aspects of intellectual functioning, such as verbal comprehension and working memory.
Free MP3: Hear Tesla Boy's '80s-Inspired Synthpop Confection 'Spirit of the Night'
Free MP3: Hear Tesla Boy's '80s-Inspired Synthpop Confection 'Spirit of the Night': If the movie Mannequin were to get a new soundtrack made by current artists, Tesla Boy's "Spirit of the Night" would be a prime contender to soundtrack a hot musical montage. The track, with its shimmering synths and bouncing bass lines, is just the kind of thing to play as Andrew McCarthy rides off into the night on his motorcycle.
What triggers a mass extinction? Habitat loss and tropical cooling were once to blame
What triggers a mass extinction? Habitat loss and tropical cooling were once to blame: The second-largest mass extinction in Earth's history coincided with a short but intense ice age. Although it has long been agreed that the so-called Late Ordovician mass extinction was related to climate change, exactly how the change produced the extinction has not been known. Now, scientists have determined that the majority of extinctions were caused by habitat loss due to falling sea levels and cooling of the tropical oceans.

Eagle Scouts have positive, lasting influence on American society, study suggests: One hundred years after the first Eagle Scout Award was presented, new research has found the significant, positive impact Eagle Scouts have on society, from leadership to giving, voting to volunteering, protecting the environment and being prepared for emergencies.
Copper-Graphene Nanocomposite Cools Electronics Faster & Cheaper
Copper-Graphene Nanocomposite Cools Electronics Faster & Cheaper:
samazon writes "North Carolina State University researcher Jag Kasichainula has developed a 'heat spreader' to cool electronics more efficiently using a copper-graphene composite, which is attached using an indium-graphene interface film. According to Kasichainula, the technique will cool 25% faster than pure copper and will cost less to produce than the copper plate heat spreaders currently used by most electronics (abstract). Better performance at a lower cost? Let's hope so."

Best Buy Scans Drivers License For Returns — No More Allowed For 90 Days
Best Buy Scans Drivers License For Returns — No More Allowed For 90 Days:
rullywowr writes "A customer with a defective Blu-Ray disc returns to the Best Buy store where he purchased it. After having his driver's license scanned into the system, he is now banned from returning/exchanging goods for 90 days. This is becoming one of the latest practices big-box stores are using to limit fraud and abuse of the return system — for example, the people who buy a giant TV before the big game and then return it on Monday. Opponents feel this return-limiting concept has this gone too far, including the harvesting of your personal data."

Wolfram Alpha now does literary analysis, breaks down the Bard's work
Wolfram Alpha now does literary analysis, breaks down the Bard's work:
Literary geeks rejoice! Wolfram Alpha has given you the tools to examine the works of William Shakespeare in ways you've never cared to imagined. Ever wondered how many words are in the second act of Othello? Or what the longest word is in A Midsummer Night's Dream? The answers to such (largely unasked) queries are now mere keystrokes away, and not just for the Bard's writings, either. That's right, folks, computational analysis of the works from such luminaries as Melville, Dickens, and Twain are on tap, too. The folks at Wolfram Alpha are also looking to increase the number of supported titles, so head on down to the source link and let them know which ones you want to see.

Statistical Analysis Raises Civil War Death Count By 20%
Statistical Analysis Raises Civil War Death Count By 20%:
Hugh Pickens writes "For more than a century, it has been accepted that about 620,000 Americans died in the the bloodiest, most devastating conflict in American history. But now, BBC reports that historian J. David Hacker has used sophisticated statistical software to determine the war's death toll and found that civil war dead may have been undercounted by as many as 130,000. Hacker began by taking digitized samples from the decennial census counts taken from 1850-1880. Using statistical package SPSS, Hacker counted the number of native-born white men of military age in 1860 and determined how many of that group were still alive in 1870 and compared that survival rate with the survival rates of the men of the same ages from 1850-1860, and from 1870-1880 — the 10-year census periods before and after the Civil War. The calculations yielded the number of 'excess' deaths of military-age men between 1860-1870 — the number who died in the war or in the five subsequent years from causes related to the war. Hacker's findings, published in the December 2011 issue of Civil War History, have been endorsed by some of the leading historians of the conflict. 'The difference between the two estimates is large enough to change the way we look at the war,' writes Hacker. 'The war touched more lives and communities more deeply than we thought, and thus shaped the course of the ensuing decades of American history in ways we have not yet fully grasped. True, the war was terrible in either case. But just how terrible, and just how extensive its consequences, can only be known when we have a better count of the Civil War dead.'"
