Don’t talk to aliens, warns Stephen Hawking
THE aliens are out there and Earth had better watch out, at least according to Stephen Hawking. He has suggested that extraterrestrials are almost certain to exist — but that instead of seeking them out, humanity should be doing all it that can to avoid any contact.
The suggestions come in a new documentary series in which Hawking, one of the world’s leading scientists, will set out his latest thinking on some of the universe’s greatest mysteries.
Alien life, he will suggest, is almost certain to exist in many other parts of the universe: not just in planets, but perhaps in the centre of stars or even floating in interplanetary space.
Hawking’s logic on aliens is, for him, unusually simple. The universe, he points out, has 100 billion galaxies, each containing hundreds of millions of stars. In such a big place, Earth is unlikely to be the only planet where life has evolved.
“To my mathematical brain, the numbers alone make thinking about aliens perfectly rational,” he said. “The real challenge is to work out what aliens might actually be like.” Read the rest of this entry »

The Sensed-Presence Effect
How the brain produces the sense of someone present when no one is there
By Michael Shermer

In the 1922 poem The Waste Land, T. S. Eliot writes, cryptically: Who is the third who always walks beside you?/When I count, there are only you and I together /But when I look ahead up the white road/There is always another one walking beside you.
In his footnotes to this verse, Eliot explained that the lines “were stimulated by the account of one of the Antarctic expeditions [Ernest Shackleton’s] … that the party of explorers, at the extremity of their strength, had the constant delusion that there was one more member than could actually be counted.”
Third man, angel, alien or deity—all are sensed presences, so I call this the sensed-presence effect. In his gripping book, The Third Man Factor (Penguin, 2009), John Geiger documents the effect in mountain climbers, solo sailors and ultraendurance athletes. He lists conditions associated with it: monotony, darkness, barren landscapes, isolation, cold, injury, dehydration, hunger, fatigue and fear. I would add sleep deprivation; Read the rest of this entry »

David Biello reports
How Will Climate Change Impact Bread?
Warming temperatures have already impacted wheat yields–in the U.S.
Listen to podcast:
Climate change may already be hitting you—in the stomach. A new analysis reveals that higher average temperatures in Montana over the last six decades equal less wheat.
Plant scientist Luther Talbert of Montana State University and his colleagues looked at weather records for the Mountain State from 1950 to 2007. The month of March has had the most warming overall, increasing by nearly 0.1 degrees Celsius per year on average. As a result, farmers now plant wheat 10 days earlier.
In addition, higher temperatures in July linked up to less wheat to harvest and lighter grains.
In 2007, the U.S. grew 12.8 million metric tons of hard red spring wheat, which is primarily used to make bread. Yields of this staple grain have increased exponentially since the 1950s because better farming practices and new wheat breeds have more than made up for those hot Julys.
Such innovations will have to continue since the future is likely to be even hotter, according to the scientists. Breeding wheat to deal with high heat is compulsory if we want our daily bread.—David Biello

Well, the liberals ON ADKOB are going to say… “here we go again”…
Yep… liberalism certainly gives me a lot to gripe about. Right now, I’m going to gripe about the capital of progressive liberalism… Hollywood.
I’ve watched the movie “Doubt”, with Meryl Streep and Philip Seymour Hoffman, several times and I now know that my first impression was correct. This movie promotes Hollywood’s ultra liberalistic movement to stifle (or completely wipe out ) Christian values. And it’s frustrating because of the great amount of influence Hollywood has. I believe, unfortunately, they will ultimately win and their views will reign in main stream society, if they don’t already.
The reason I say that I “now know” that my first impression of the movie is correct is because, on the surface, the movie seems to be very ambiguous. Even to the end, we can’t truly be sure who the protagonist is and who is the antagonist. But really, one could know this just by learning of the major components…. a staunch, hard lined, by the “Book” Catholic (CHRISTIAN) Nun, a Priest who wants to “modernize” or “LIBERALIZE” the church, and Hollywood. And to be more descriptive… a Nun who holds on to traditional Christian values and a Priest who believes that “love” is the most important thing above all, but… oh yeah, this kind of “love” just happens to express itself sometimes through sexual contact with a 12 year old boy.

This is an excerpt from a message from Harry Reid addressing the TV ad attacks put out by a republican senatorial candidate. I am not a supporter of Harry Reid but I do support healthcare/insurance reform and the points covered here clearly explains the facts and reasons for reform.
Yesterday a Republican running for the Senate launched a TV ad attacking Harry Reid for supporting health insurance reform, calling it “government run health care.” The spot recycles the same tired insurance company talking points we’ve heard over the past year.
LIE #1: Health insurance reform is “one-size-fits-all government run health care”
TRUTH: If families have coverage and like their plan they can keep it, and are protected against insurance company abuses.
LIE #2: We think ‘Washington’ knows best
TRUTH: Families in Nevada and around the country know best, that’s why the Senate bill gives them more insurance choices.
LIE #3: The Senate’s ‘big government’ health care plan will raise taxes
TRUTH: Right now families pay more than $1,000 each year to cover people who don’t have health insurance – it’s a hidden tax and reforming insurance eliminates it by giving every American access to quality, affordable coverage. Read the rest of this entry »

Wired.com marks Presidents Day weekend with brief vignettes of three of our techiest presidents: Washington steered national policy toward an embrace of science, Jefferson made a significant contribution to paleontology, and Lincoln devised and patented a gimmick for lifting stranded boats.
The Library of Congress has this manuscript of George Washington’s first State of the Union address.
Jan. 8, 1790: During his first — and the nation’s first — State of the Union address, President George Washington urges the young nation to encourage the sciences and literature, calling knowledge “the surest basis for public happiness.”
He also called for importing “useful inventions from abroad” while encouraging homegrown genius to flourish, by means of offering patent protection for inventors.
Washington was trained as a surveyor, and he attached great importance to the study of science and literature. His views also reflected the general attitude of the gentry toward classical education. The Founding Fathers, most of who came from this class, were children of the Enlightenment, the philosophy of rationalism that rose in Europe during the 17th and 18th centuries.
