The beauty of life is, while we cannot undo what is done,
we can see it, understand it, learn from it and change.
So that every new moment is spent not in regret, guilt, fear or anger,
but in wisdom, understanding and love. - Jennifer Edwards
At long last, the doodling daydreamer is getting some respect.
In the past, daydreaming was often considered a failure of mental discipline, or worse. Freud labeled it infantile and neurotic. Psychology textbooks warned it could lead topsychosis. Neuroscientists complained that the rogue bursts of activity on brain scans kept interfering with their studies of more important mental functions.
But now that researchers have been analyzing those stray thoughts, they’ve found daydreaming to be remarkably common — and often quite useful. A wandering mind can protect you from immediate perils and keep you on course toward long-term goals. Sometimes daydreaming is counterproductive, but sometimes it fosters creativity and helps you solve problems.
Consider, for instance, these three words: eye, gown, basket. Can you think of another word that relates to all three? If not, don’t worry for now. By the time we get back to discussing the scientific significance of this puzzle, the answer might occur to you through the “incubation effect” as your mind wanders from the text of this article — and, yes, your mind is probably going to wander, no matter how brilliant the rest of this column is.
Mind wandering, as psychologists define it, is a subcategory of daydreaming, which is the broad term for all stray thoughts and fantasies, including those moments you deliberately set aside to imagine yourself winning the lottery or accepting the Nobel. But when you’re trying to accomplish one thing and lapse into “task-unrelated thoughts,” that’s mind wandering. Read the rest of this entry »
May 19, 2009—Meet “Ida,” the small “missing link” found in Germany that’s created a big media splash and will likely continue to make waves among those who study human origins.
In a new book, documentary, and promotional Web site, paleontologist Jorn Hurum, who led the team that analyzed the 47-million-year-old fossil seen above, suggests Ida is a critical missing-link species in primate evolution (interactive guide to human evolution from National Geographic magazine).
(Among the team members was University of Michigan paleontologist Philip Gingerich, a member of the Committee for Research and Exploration of the National Geographic Society, which owns National Geographic News.)
The fossil, he says, bridges the evolutionary split between higher primates such as monkeys, apes, and humans and their more distant relatives such as lemurs.
“This is the first link to all humans,” Hurum, of the Natural History Museum in Oslo, Norway, said in a statement. Ida represents “the closest thing we can get to a direct ancestor.”
Ida, properly known as Darwinius masillae, has a unique anatomy. The lemur-like skeleton features primate-like characteristics, including grasping hands, opposable thumbs, clawless digits with nails, and relatively short limbs.
“This specimen looks like a really early fossil monkey that belongs to the group that includes us,” said Brian Richmond, a biological anthropologist at George Washington University in Washington, D.C., who was not involved in the study, published this week in the journal PLoS ONE.
But there’s a big gap in the fossil record from this time period, Richmond noted. Researchers are unsure when and where the primate group that includes monkeys, apes, and humans split from the other group of primates that includes lemurs.
“[Ida] is one of the important branching points on the evolutionary tree,” Richmond said, “but it’s not the only branching point.”
At least one aspect of Ida is unquestionably unique: her incredible preservation, unheard of in specimens from the Eocene era, when early primates underwent a period of rapid evolution. (Explore a prehistoric time line.)
“From this time period there are very few fossils, and they tend to be an isolated tooth here or maybe a tailbone there,” Richmond explained. “So you can’t say a whole lot of what that [type of fossil] represents in terms of evolutionary history or biology.”
In Ida’s case, scientists were able to examine fossil evidence of fur and soft tissue and even picked through the remains of her last meal: fruits, seeds, and leaves.
What’s more, the newly described “missing link” was found in Germany’s Messel Pit. Ida’s European origins are intriguing, Richmond said, because they could suggest—contrary to common assumptions—that the continent was an important area for primate evolution.

SEOUL, South Korea – South Korean scientists say they have engineered four beagles that glow red using cloning techniques that could help develop cures for human diseases. The four dogs, all named “Ruppy” — a combination of the words “ruby” and “puppy” — look like typical beagles by daylight.
But they glow red under ultraviolet light, and the dogs’ nails and abdomens, which have thin skins, look red even to the naked eye.
Seoul National University professor Lee Byeong-chun, head of the research team, called them the world’s first transgenic dogs carrying fluorescent genes, an achievement that goes beyond just the glowing novelty.
“What’s significant in this work is not the dogs expressing red colors but that we planted genes into them,” Lee told The Associated Press on Tuesday.
His team identified the dogs as clones of a cell donor through DNA tests and earlier this month introduced the achievement in a paper on the Web site of the journal “Genesis.”
Scientists in the U.S., Japan and in Europe previously have cloned fluorescent mice and pigs, but this would be the first time dogs with modified genes have been cloned successfully, Lee said.
He said his team took skin cells from a beagle, inserted fluorescent genes into them and put them into eggs before implanted them into the womb of a surrogate mother, a local mixed breed.
Six female beagles were born in December 2007 through a cloning with a gene that produces a red fluorescent protein that make them glow, he said. Two died, but the four others survived.
The glowing dogs show that it is possible to successfully insert genes with a specific trait, which could lead to implanting other, non-fluorescent genes that could help treat specific diseases, Lee said.
The scientist said his team has started to implant human disease-related genes in the course of dog cloning, saying that will help them find new treatments for genetic diseases such as Parkinson’s. He refused to provide further details, saying the research was still under way.
A South Korean scientist who created glowing cats in 2007 based on a similar cloning technique said that Lee’s puppies are genuine clones, saying he had seen them and had read about them in the journal.
“We can appraise this is a step forward” toward finding cures for human diseases, said veterinary professor Kong Il-keun at South Korea’s Gyeongsang National University. “What is important now is on what specific diseases (Lee’s team) will focus on.”
Lee was a key aide to disgraced scientist Hwang Woo-suk, whose breakthroughs on stem cell research were found to have been made using faked data. Independent tests, however, later proved the team’s dog cloning was genuine.

If you fear Friday the 13th, then batten down the hatches. This week’s unlucky day is the first of three this year.
The next Friday the 13th comes in March, followed by Nov. 13. Such a triple whammy comes around only every 11 years, said Thomas Fernsler, a math specialist at the University of Delaware who has studied the number 13 for more than 20 years.
By the numbers
Here are 13 more facts about the infamous day, courtesy of Fernsler and some of our own research:
1. The British Navy built a ship named Friday the 13th. On its maiden voyage, the vessel left dock on a Friday the 13th, and was never heard from again.
2. The ill-fated Apollo 13 launched at 13:13 CST on Apr. 11, 1970. The sum of the date’s digits (4-11-70) is 13 (as in 4+1+1+7+0 = 13). And the explosion that crippled the spacecraft occurred on April 13 (not a Friday). The crew did make it back to Earth safely, however.
3. Many hospitals have no room 13, while some tall buildings skip the 13th floor.
4. Fear of Friday the 13th — one of the most popular myths in science — is called paraskavedekatriaphobia as well as friggatriskaidekaphobia. Triskaidekaphobia is fear of the number 13.
5. Quarterback Dan Marino wore No. 13 throughout his career with the Miami Dolphins. Despite being a superb quarterback (some call him one of the best ever), he got to the Super Bowl just once, in 1985, and was trounced 38-16 by the San Francisco 49ers and Joe Montana (who wore No. 16 and won all four Super Bowls he played in).
6. Butch Cassidy, notorious American train and bank robber, was born on Friday, April 13, 1866.
7. Fidel Castro was born on Friday, Aug. 13, 1926.
8. President Franklin D. Roosevelt would not travel on the 13th day of any month and would never host 13 guests at a meal. Napoleon and Herbert Hoover were also triskaidekaphobic, with an abnormal fear of the number 13.
9. Superstitious diners in Paris can hire a quatorzieme, or professional 14th guest.
10. Mark Twain once was the 13th guest at a dinner party. A friend warned him not to go. “It was bad luck,” Twain later told the friend. “They only had food for 12.”
11. Woodrow Wilson considered 13 his lucky number, though his experience didn’t support such faith. He arrived in Normandy, France on Friday, Dec. 13, 1918, for peace talks, only to return with a treaty he couldn’t get Congress to sign. (The ship’s crew wanted to dock the next day due to superstitions, Fernsler said.) He toured the United States to rally support for the treaty, and while traveling, suffered a near-fatal stroke.
12. The number 13 suffers from its position after 12, according to numerologists who consider the latter to be a complete number — 12 months in a year, 12 signs of the zodiac, 12 gods of Olympus, 12 labors of Hercules, 12 tribes of Israel, 12 apostles of Jesus, 12 days of Christmas and 12 eggs in a dozen.
13. The seals on the back of a dollar bill include 13 steps on the pyramid, 13 stars above the eagle’s head, 13 war arrows in the eagle’s claw and 13 leaves on the olive branch. So far there’s been no evidence tying these long-ago design decisions to the present economic situation.
Origins of Friday the 13th
Where’s all this superstition come from? Nobody knows for sure. But it may date back to Biblical times (the 13th guest at the Last Supper betrayed Jesus). By the Middle Ages, both Friday and 13 were considered bearers of bad fortune.
Meanwhile the belief that numbers are connected to life and physical things — called numerology — has a long history.
“You can trace it all the way from the followers of Pythagoras, whose maxim to describe the universe was ‘all is number,’” says Mario Livio, an astrophysicist and author of “The Equation That Couldn’t Be Solved” (Simon & Schuster, 2005). Thinkers who studied under the famous Greek mathematician combined numbers in different ways to explain everything around them, Livio said.
In modern times, numerology has become a type of para-science, much like the meaningless predictions of astrology, scientists say.
“People are subconsciously drawn towards specific numbers because they know that they need the experiences, attributes or lessons, associated with them, that are contained within their potential,” says professional numerologist Sonia Ducie. “Numerology can ‘make sense’ of an individual’s life (health, career, relationships, situations and issues) by recognizing which number cycle they are in, and by giving them clarity.”
Mathematicians dismiss numerology as having no scientific merit, however.
“I don’t endorse this at all,” Livio said, when asked to comment on the popularity of commercial numerology for a story prior to the date 06/06/06. Seemingly coincidental connections between numbers will always appear if you look hard enough, he said.
