Mr. Lehrer released a statement Monday through his publisher, Houghton Mifflin Harcourt, saying that some Dylan quotes appearing in "Imagine: How Creativity Works" did "not exist." Others were "unintentional misquotations, or represented improper combinations of previously existing quotes."

Lehrer said he acknowledged his actions after being contacted by Michael Moynihan of the online publication Tablet Magazine, which earlier Monday released an in-depth story on the Dylan passages in "Imagine."

"I told Mr. Moynihan that they (the quotes in question) were from archival interview footage provided to me by Dylan's representatives. This was a lie spoken in a moment of panic. When Mr. Moynihan followed up, I continued to lie, and say things I should not have said," Lehrer wrote in his statement.

"The lies are over now. I understand the gravity of my position. I want to apologize to everyone I have let down, especially my editors and readers."

Houghton Mifflin said in a statement that Lehrer had committed a "serious misuse." Listings for the e-book edition of "Imagine" will be removed and shipments of the physical book have been stopped. "Imagine," published in March, has sold more than 200,000 copies, according to Houghton Mifflin. It has spent 16 weeks on The New York Times' hardcover nonfiction bestseller list and ranked No. 105 on Amazon.com as of midday Monday. Amazon had cited the book as among the best March releases.

A spokesman for Dylan did not immediately respond to a request for comment.

Over the past decade, numerous books have been pulled, whether because of lifting material from other sources (Q.R. Markham's "Assassin of Secrets") or fabricating events (James Frey's "A Million Little Pieces"). Canceled books inevitably lead to calls for publishers to fact check releases. But publishers say the time and expense of reviewing thousands of texts, on a vast range of subjects, makes the process impractical.

"Publishing books is fundamentally different from publishing a newspaper or magazine," Bruce Nichols, Houghton Mifflin's senior vice president and publisher of adult trade books, said in a statement. "We rely on the authors' contractual warranties that the work is original and, for non-fiction, accurate.

"Nonetheless we consider accuracy and originality to be essential standards, and whenever any of our authors transgresses these standards we take it very seriously."

The 31-year-old Lehrer had been a rising star at The New Yorker, which is famous for its thorough fact checking. But he was already in trouble with the magazine after he acknowledged last month that he had recycled passages he had written for previous publications. Some recycled passages also appeared in "Imagine," the latest of three books by Lehrer, who is known for his explorations of science and literature and how the mind works.

"This is a terrifically sad situation, but, in the end, what is most important is the integrity of what we publish and what we stand for," said New Yorker Editor David Remnick.

Among Lehrer's inventions was a quote that first appeared in the famous documentary from the mid-1960s, "Don't Look Back," in which Dylan tells a reporter about his songs that "I just write them. There's no great message." In "Imagine," Lehrer adds a third sentence ? "Stop asking me to explain" ? that does not appear in the film.

According to Tablet, Lehrer also invented quotes on how Dylan wrote "Like a Rolling Stone" and, when confronted about them, alleged that he had been granted access to an uncut version of "No Direction Home," a Dylan documentary made by Martin Scorsese. Lehrer now says he never saw such footage.

Dylan himself has been challenged about his use of material. His album "Modern Times" included lines lifted from blues songs and from the Civil War poet Henry Timrod. An exhibit of paintings by the rock star turned out to contain images from other sources.

Twitter suspends journalist who complained about NBC?s Olympics coverage

Keep your opinions about NBC to yourself, lest the ban hammer fall once againIf you've taken to Twitter over the past 48 hours or so, the negative sentiment regarding NBC's handling of the 2012 Olympics coverage is somewhat inescapable. One particular tweeter named Guy Adams ? who also happens to work for news outlet The Independent ? apparently crossed the line when he posted the email address of NBC sports executive Gary Zenkel and suggested that viewers contact him with complaints. Adams account has now been suspended from Twitter.

Of course, Adams isn't the only social network user that has a bone to pick with NBC regarding its Olympics plans.?Viewers are leveling myriad complains against the broadcasting giant, ranging from a perceived excess of advertisements, to the unfortunate decision to tape delay almost all of the most popular events in order to shoehorn them into primetime slots.

After his account was suspended, Adams contacted Twitter support for an explanation. The social network responded by citing a somewhat muddy rule against posting others' personal information against their will, including email addresses. Of course, you can very easily find Zenkel's email address with a simple Google search, but NBC still found enough cause to file an official Twitter complaint.

Did Adams's tweet cross the line of good taste? Perhaps, but it probably isn't cause to suspend the reporter's account. It should also be noted that NBC and Twitter are currently partnered up for cross promotion during Olympic coverage, with the social network providing commentary for live events. Whether this buddy system played a role in Adams's ban will, of course, never be known.

Researchers identify potential treatment target for metastatic pancreatic cancer using CTC chip technology

(Medical Xpress) -- Researchers with the Stand Up To Cancer CTC Chip Dream Team have identified a potential treatment target in metastatic pancreatic cancer through a detailed analysis of genes expressed in circulating tumor cells (CTCs) ? cells that break off from solid tumors and travel through the bloodstream.

In a study that will appear today in the print edition of Nature and received advanced publication online earlier this month, the Dream Team reported finding increased expression of WNT2, a member of a known family of oncogenes, in CTCs from mouse models of pancreatic cancer and from human patients.

The SU2C Dream Team ?Bioengineering and Clinical Applications of Circulating Tumor Cell Chip? is led by Daniel A. Haber, M.D., Ph.D., director of the Massachusetts General Hospital (MGH) Cancer Center, and Mehmet Toner, Ph.D., director of the Massachusetts General Hospital Center for Bioengineering in Medicine in Boston.

?Studying cancer cells as they circulate in the blood is a critical way to figure out how cancer spreads and finding ways to try to block that,? said Haber. ?It has taken a real partnership between engineers, biologists and clinicians to develop the technology to fish out these incredibly rare cells in the blood, study them with molecular tools and start applying these findings toward new treatments.?

Haber and colleagues used the second-generation version of the CTC chip ? developed with support from the SU2C grant ? to isolate CTCs from mice that were genetically engineered to develop pancreatic cancer. They then compared gene expression between the CTCs in the blood and cancer cells within the pancreatic tumor, to look for genes that helped tumor cells invade into the bloodstream. The team was able to identify several genes that were expressed at higher levels in the CTCs. From this group of genes, WNT2 (a member of a signaling pathway known for its role in embryogenesis and cancer) was selected for further investigation. Results showed that WNT2 was highly expressed in CTCs and metastases. These findings were in contrast to primary tumors, in which WNT2 was rarely expressed.

Through further studies, the Dream Team ultimately showed that WNT2 might be responsible for the CTC?s ability to escape ?anoikis? ? one of the body?s normal mechanisms to eliminate these cells as they circulate in the blood. If CTCs are not eliminated, they have an increased chance of establishing metastases.

The team also identified a drug that blocks a step in the WNT2 pathway, thereby suppressing the ability of CTCs to survive in the bloodstream. This drug is not available for clinical use and further studies would be needed to test its efficacy in patients with pancreatic cancer. While most of the work was performed using a mouse model of pancreatic cancer, the team found that similar mechanisms appear to operate in CTCs from patients with pancreatic cancer.

This study sheds new light on how pancreatic cancer cells may metastasize, and identifies a potential drug target for interrupting the WNT pathway and limiting the chance for metastases to spread to other organs.

sandstone paving, stone cladding - Stone Cladding:Beautifying Your ...











Would you like to improve the appearance of your home? Try perth stone paving. This has countless distinct functions for garden landscaping. You could find these smooth-textured pavers in patios, sidewalks, driveways. Contractors and landscape design specialists use them frequently for garden walls, borders, and seats. Additionally, they set this all around private pools or use this to create steps, retain walls, or stepping-stones. Your homebuilder or artist may incorporate pavers of various styles, sizes, and tones to make a stylish paving design. Here is additional information concerning this option.

Sandstone Paving: Beautifying Gardens

Sandstone paving is popular in garden areas. These pavers can be piled over one another to make short walls all-around a garden or fountain. Your homebuilder ought to place mortar in between the pavers to help keep the construction from falling over. Sandstone pavers make good-looking borders trimming around patios, driveways, and gardens.

You may place sandstone pavers about private pools for a vivid and attractive surface area. The earth-toned colors of sandstone usually contrast perfectly with the pool colour. Your building contractors may use a sealer to guard the sandstone from deteriorating from saltwater or sunlight. They can even utilize sandstone pool coping along side the side of the pool for a consistent appearance. They could even use special non-slip coatings to the surface for security.

Homebuilders may install these pavers as steps leading to the entranceway, patio, deck, or porch for a resort-like feel. Setting up the stones in a mortar base can even them out and keep them long lasting. You may turn sandstone pavers on their sides to make a small retaining wall over the side of the steps.

You may use stone cladding for both the interior and exterior of your home to add inventive and decorative feature. You will discover this inside a home, near fireplaces and walls. On the exterior, home builders utilize stone cladding over the framing or affixed on outside walls- either siding or brick to offer a durable finish.

Here are popular types of stone cladding:

-Solid Stone

This is the most favorite kind of stone cladding. This is naturally hefty and difficult to move. Even though some people still construct homes entirely out of polished stone, it is more common to utilize this as an accent. These are great for chimneys, or a single wall.

-Faux Stone

Faux stone is a manufactured product that appears and feels like real stone. It is available in lots of tones, shapes and sizes. The only real distinction is its weight- it is lighter than authentic stone. Makers create faux stone from poured concrete and shape this into slate pieces or stones using moulds. As opposed to real stone, you don't need to seal this to prevent wetness from seeping within.

-Polyurethane Foam Panels

This sort of stone cladding features the appearance of real stone but none of its weight. They are really light and resistant to moisture. Also, they are easy to install and ship. You can set these over existing siding or interior walls, boosting the efficiency of your insulation.

With sand stone paving and cladding you could make your house more appealing and long lasting. Get top quality materials and employ specialists for proper installation.
