Researchers 3D-Print Heart From Human Patient's Cells
Researchers have 3D-printed a heart using a patient's cells, providing hope that the technique could be used to heal hearts or engineer new ones for transplants. "This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers," Professor Tal Dvir of Tel Aviv University's School of Molecular Cell Biology and Biotechnology said in a statement. Dvir is senior author of the research, published Monday in the journal Advanced Science. CNN reports: The process of printing the heart involved a biopsy of the fatty tissue that surrounds abdominal organs. Researchers separated the cells in the tissue from the rest of the contents, namely the extracellular matrix linking the cells. The cells were reprogrammed to become stem cells with the ability to differentiate into heart cells; the matrix was processed into a personalized hydrogel that served as the printing "ink."
The cells and hydrogel were first used to create heart patches with blood vessels and, from there, an entire heart. Next, the researchers plan to train the hearts to behave like hearts, Dvir explained. "The cells need to form a pumping ability; they can currently contract, but we need them to work together." If researchers are successful, they plan to transplant the 3D-printed heart in animal models and, after that, humans. -
Non-Profit Org Claims Rights In Library Catalog Data
lamona writes "The main source of the bibliographic records that are carried in library databases is a non-profit organization called OCLC. Over the weekend OCLC 'leaked' its new policy that claims contractual rights in the subsequent uses of the data, uses such as downloading book information into Zotero or other bibliographic software. The policy explicitly forbids any use that would compete with OCLC. This would essentially rule out the creation of free and open databases of library content, such as the Open Library and LibraryThing. The library blogosphere is up in arms . But can our right to say: "Twain, Mark. The adventures of Tom Sawyer" be saved?" -
Hotel Being Sued for Using the Dewey Decimal System
cbull writes "Did you know the Dewey Decimal System isn't in the public domain? The rights are owned by the Online Computer Library Center. They are suing the Library Hotel in New York for trademark infringement. In addition, according to the article, libraries pay at least $500/year to use the system." -
Libraries Are 31337
tiltowait writes In response to the incredulity expressed in this story about the technical prowess of libraries, I'd like to present a short essay titled "Librarians: We're Not What You Think" - read on for more. Update: 10/20 18:15 GMT by M : The author has also put up his essay on his own webpage. From the spinster librarian in It's a Wonderful Life to the crochety archivist in Attack of the Clones, librarians are often portrayed (in everything from movies, musicals, children's books, literature, science fiction, comics and cartoons to pornography - yes, pornography) as something less than noble or admirable. The perception of librarians has been a popular topic recently, with several articles focusing on the fringe-type librarians (ska, rockabilly, bellydancing, modified, bodybuilding, laughing, and lipstick). Although something of an anti-stereotype, these people illustrate the range of librarian personalities.Many people may hold the image of a librarian as a shushing school marm who does little more than stamp and shelve books because that's all they've seen librarians do. Well think again - that's about as inaccurate as believing that Alan Greenspan is nothing more than a glorified bank teller. The job titles may change but the mission of the profession remains the same: organize information and help people find it. Libraries have been around a lot longer than the Internet, and even library technology can hold its own with the best out there. For example, Google's savvy results ranking was hardly the birth of citation analysis (next up: metadata - cough, cataloging, cough), and there are enormous library systems that also predate the Internet.
Although library geeks and technology nerds may have contrary images, in today's world the boundary between the career of the librarian and the information technologist is disappearing. Librarians today not only administer Web servers and dynamic databases to help manage large digital collections and thousands of electronic resources, they teach people how to use library systems. And just as enlightened computer engineers are advocates of noncommercial software and campaign for online rights, the library profession has a long history of staunchly defending freedom - from book burnings to the FBI's Library Awareness Program to the latest copyright battles and almost all other current issues in intellectual freedom.
