New Rochelle, NY, November 10, 2014--To understand their risk for hereditary forms of cancer, such as breast and colon cancer, women need to know their family history. The design and effectiveness of a 20-minute skills-based intervention that can help women better communicate with relatives and gather and share information about cancer family history is described in a study in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Women's Health website at http://online.liebertpub.com/doi/full/10.1089/jwh.2014.4754 until December 10, 2014.

In the article "The KinFact Intervention - A Randomized Controlled Trial to Increase Family Communication About Cancer History," Joann Bodurtha, MD, and coauthors from Johns Hopkins University (Baltimore, MD), Virginia Commonwealth University (Richmond, VA), and Boston University (MA), describe the Keeping Information about Family Cancer Tune-up Program (KinFact) intervention.

KinFact participants were significantly more likely to gather and share family cancer information with relatives and to communicate with them more often than were women who instead received a handout about lowering cancer risk and cancer screening. The authors found that the effectiveness of KinFact varied depending on whether women were pregnant and on their level of genetic literacy.

"Communication within families about cancer diagnoses and risk is difficult, and interventions like KinFact are useful to better understand patients' family health risks," says Susan G. Kornstein, MD, Editor-in-Chief of Journal of Women's Health, Executive Director of the Virginia Commonwealth University Institute for Women's Health, Richmond, VA, and President of the Academy of Women's Health.

New Rochelle, NY, November 10, 2014--The Centers for Disease Control and Prevention (CDC) lists numerous potential alternative sources of HIV transmission in addition to the known classical modes for acquiring the AIDS virus. Although manicure instruments is not on this list of alternative sources, a case of HIV transmission that may be linked to sharing of manicure instruments is presented in AIDS Research and Human Retroviruses, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article appears in special issue on HIV Prevention Science and is available free on the AIDS Research and Human Retroviruses website at http://online.liebertpub.com/doi/full/10.1089/aid.2014.0264 until December 10, 2014.

In the article "An HIV-1 Transmission Case Possibly Associated with Manicure Care," Elaine Monteiro Matsuda and coauthors from Santo Andr AIDS Program, Adolfo Lutz Institute, and University of So Paulo, Brazil, describe the case of a 22-year-old woman who had advanced HIV infection but no apparent risk factors for acquiring HIV. She reported having shared manicure instruments years before with a cousin who was later found to be HIV-positive. Genetic analysis of the viruses from both patients suggests that they shared a common viral ancestor, indicating the possibility that HIV was transmitted via the manicure instruments.

"HIV is not transmitted by casual contact, such as sharing eating utensils, or drinking from the same water glass," says AIDS Research and Human Retroviruses Basic Sciences Editor/Sequence Notes Brian Foley, PhD, HIV Sequence Database, Los Alamos National Laboratory, NM. "This transmission of HIV by shared manicure equipment is a very rare event that should serve not to make people fear HIV or contact with HIV-infected people. It should make people aware that sharing any utensils with possible blood-blood contact, such as needles used for drugs, tattoos, or acupuncture can result in transmission of viruses such as hepatitis C (HCV) and HIV. In addition, there are other common viruses and bacteria that can also be spread by sharing equipment without proper disinfection between users."

New laser scans of the dodo, perhaps the most famous animal to have gone extinct in human history, have unexpectedly exposed portions of its anatomy unknown to science, which are revealing secrets about how the bird once lived.

The dodo was a flightless bird about 3 feet (1 meter) tall that was native to the island of Mauritius in the Indian Ocean. It went extinct by 1693, less than a century after the Dutch discovered the island in 1598, killed off by creatures such as rats and pigs, which sailors introduced to Mauritius either accidentally or intentionally.

The giant bird was actually a type of pigeon. "The skull of the dodo is so large and its beak so robust that it is easy to understand that the earliest naturalists thought it was related to vultures and other birds of prey, rather than the pigeon family," said study co-author Hanneke Meijer at the Catalan Institute of Paleontology in Spain.

Surprisingly, despite the dodo's fame, and the fact the bird was alive during recorded human history, little is known about the anatomy and biology of this animal. "The dodo's extinction happened at a time when people didn't understand the concept of extinction science as we know it was still in its infancy,"lead study author Leon Claessens, a vertebrate paleontologist at the College of the Holy Cross in Worcester, Massachusetts, told Live Science. "This meant that nobody tried to make a collection of the bird or study it in detail." [Wipe Out! History's 7 Most Mysterious Extinctions]

To shed new light on the dodo, Claessens and his colleagues went to the Natural History Museum in Port Louis, Mauritius, to investigate the only known complete skeleton from a single dodo. All other dodo skeletons are composites of several birds.

Amateur naturalist and barber Etienne Thirioux found the specimen the researchers analyzed near Le Pouce Mountain on Mauritius in about 1903. It was unstudied by scientists until now.

The scientists used a laser scanner to create a 3D digital model of the specimen. In addition, they scanned a second dodo skeleton Thirioux also created, a composite of two or more skeletons that was housed at the Durban Museum of Natural Science in South Africa.

"We discovered that the anatomy of the dodo we were looking at was not previously described in detail," Claessens said. "There were bones of the dodo that were just unknown to science until now."

New Rochelle, NY, November 6, 2014--Lower-cost 3D printers for the consumer market offer only a limited selection of plastic materials, while industrial additive manufacturing (AM) machines can print parts made of high-performance metals. The application of a novel process called Selective Inhibition Sintering (SIS) in a consumer-priced metal AM machine is described in an article in 3D Printing and Additive Manufacturing, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the 3D Printing and Additive Manufacturing website until December 6, 2014.

Payman Torabi, Matthew Petros, and Behrokh Khoshnevis, University of Southern California, Los Angeles, explain this innovative process, present sample parts printed using the technology, and discuss the next steps in research and development in the article "SIS -- The Process for Consumer Metal Additive Manufacturing" The SIS process differs from traditional research in powder sintering, which focuses on enhancing sintering (a process of fusing materials using heat and pressure); instead, SIS prevents sintering in selected regions of each powder layer.

"This technology uses a fundamentally new approach to 3D printing, one that could expand the reach of metal printing," says Editor-in-Chief Hod Lipson, PhD, Professor at Cornell University's Sibley School of Mechanical and Aerospace Engineering, Ithaca, NY.

A 9,300-year-old frozen bison mummy has been found in Eastern Siberia, according to a presentation this week at the Society of Vertebrate Paleontologys Annual Meeting in Berlin.

The still-furry beast is one of the most complete frozen mummies ever found. It literally freezes in time the appearance and anatomy of a steppe bison (Bison priscus), whose species went extinct shortly after the end of the Ice Age.

Mummies Faces,Hair-dos, Revealed in 3D: Photos

Its been named the Yukagir bison mummy, after the region where it was found.

The exceptionally good preservation of the Yukagir bison mummy allows direct anatomical comparisons with modern species of bison and cattle, as well as with extinct species of bison that were gone at the Pleistocene-Holocene boundary, co-author Evgeny Maschenko from the Paleontological Institute in Moscow was quoted as saying in a press release.

The remarkable specimen still has its complete brain, heart, blood vessels and digestive system. Some of its organs have significantly shrunk over time, but thats to be expected given its advanced age.

The researchers, led by Natalia Serduk of the Russian Academy of Sciences in Moscow, conducted a necropsy on the remains. The investigation determined that the bison showed a relatively normal anatomy. A clue to its demise, however, is a lack of fat around its abdomen. This suggests that the bison died from starvation, but the scientists arent sure of that yet.

Compared to todays bison in America, the Ice Age bison sported much larger horns and a second back hump. Steppe bison like this now-frozen one were commonly featured in Stone Age cave art, often shown being hunted by humans.

Remains for a woolly rhino, a 35,00039,000-year-old horse, and a mammoth were also recently found near the Siberian site where the bison mummy was discovered.
