Scientists announce discovery of first horned dinosaur from South Korea

2010-12-07
(Press-News.org) Cleveland - Scientists from South Korea, the United States and Japan analyzed fossil evidence found in South Korea and published research describing a new horned dinosaur. The newly identified genus, Koreaceratops hwaseongensis, lived about 103 million years ago during the late Early Cretaceous period. The specimen is the first ceratopsian dinosaur from the Korean peninsula. The partial skeleton includes a significant portion of the animal's backbone, hip bone, partial hind limbs and a nearly complete tail. Results from the analysis of the specimen were published in the 18 November 2010 online edition of the journal Naturwissenchaften: The Science of Nature.

The Koreaceratops hwaseongensis is named for Korea and Hwaseong City, which yielded the fossil. It was discovered in 2008 in a block of rock along the Tando Basin reservoir. It is one of the first articulated dinosaurs known from Korea.

"This is a rare find," said Michael J. Ryan, Ph.D., curator and head of Vertebrate Paleontology at The Cleveland Museum of Natural History, who co-authored the research. "Fossils of dinosaurs have not typically been found in this region, whereas evidence of dinosaur eggs and footprints occur more commonly. This specimen is significant because it fills in a missing 20 million-year gap in the fossil record between the origin of these dinosaurs in Asia and their first appearance in North America."

At approximately 5 to 6 feet long and weighing about 60 to 100 pounds, the animal was relatively small compared to the geologically younger, giant relatives like Triceratops found in North America. Koreaceratops had a parrot-like face with a beak at the front of its jaws, indicating it was an herbivore. The claws on its hind feet suggest that it was bipedal and moved at a fairly rapid speed. Koreaceratops had a unique fan-shaped tail formed by long neural spines, which suggests it may have been a good swimmer, and spent part of its time hunting for aquatic food.

INFORMATION:

Yuong-Nam Lee of the Korea Institute of Geoscience and Mineral Resources was lead author on the research. Yoshitsugu Kobayashi of the Hokkaido University Museum in Japan was third author.

Penn study on skin formation suggests strategies to fight skin cancer
2010-12-07
PHILADELPHIA - In a study published in the journal Developmental Cell, Sarah Millar PhD, professor of Dermatology and Cell & Developmental Biology at the University of Pennsylvania School of Medicine, and colleagues demonstrate that a pair of enzymes called HDACs are critical to the proper formation of mammalian skin. The findings, Millar says, not only provide information about the molecular processes underlying skin development, they also suggest a potential anticancer strategy. "Inhibition of these HDAC enzymes might be able to shut down the growth of tumors that ...

Bacteria seek to topple the egg as top flu vaccine tool

2010-12-07
Only the fragile chicken egg stands between Americans and a flu pandemic that would claim tens of thousands more lives than are usually lost to the flu each year. Vaccine production hinges on the availability of hundreds of millions of eggs – and even with the vaccine, flu still claims somewhere around 36,000 lives in the United States during a typical year. Now scientists have taken an important step toward ending the dominance of the oval. In a paper published in the Dec. 6 issue of the journal Vaccine, scientists showed that an experimental flu vaccine grown entirely ...

NIH scientists identify mechanism responsible for spreading biofilm infections

2010-12-07
What: Scientists from the National Institutes of Health have discovered how catheter-related bacterial infection develops and disseminates to become a potentially life-threatening condition. The study, which included research on Staphylococcus epidermidis in mice implanted with catheters, could have important implications for understanding many types of bacterial biofilm infections, including those caused by methicillin-resistant S. aureus (MRSA). Biofilms are clusters of microbes that almost always are found with healthcare-associated infections (HAIs) involving medical ...

Iron deficiency in soil threatens soybean production

2010-12-07
Madison, WI December 6 2010 -- An expansion of soybean production into areas where soybean has seldom, if ever, been grown can be problematic for some farmers. Soils having high pH values and large amounts of calcium and/or magnesium carbonate are notoriously iron deficient. Iron deficient soils in the North Central United States are estimated to reduce soy bean production by 12.5 million bushels every year. John Wiersma, a researcher at the University of Minnesota Northwest Research and Outreach Center at Crookston, concluded a study examining the effect of nitrogen based ...

UNC expert: Combining exenatide with insulin may be 'best result ever' for diabetes patients

2010-12-07
CHAPEL HILL, N.C. – A new study finds that combining the newer diabetes drug exenatide with insulin provides better blood sugar control in patients with type 2 diabetes than insulin alone and helps promote weight loss. "This study may be the best result ever for patients whose diabetes is inadequately controlled on a combination of pills and insulin," said John Buse, MD, PhD, lead author of the study and chief of the Division of Endocrinology and Metabolism in the University of North Carolina at Chapel Hill School of Medicine. "Until now, it was inconceivable that you ...

Personalized vaccine for lymphoma patients extends disease-free survival by nearly 2 years

2010-12-07
(ORLANDO, Fla.) – A personalized vaccine is a powerful therapy to prevent recurrence among certain follicular lymphoma patients, according to the latest results of ongoing research led by the University of Pennsylvania School of Medicine. The new findings show that when these patients – whose tumors are marked by a specific protein that may be present in up to half of people with this type of cancer -- receive a vaccine made from their own tumor cells, disease-free survival is improved by nearly two years, compared with patients who receive a placebo. Based on the new analysis, ...

Learning the language of bacteria

2010-12-07
MADISON — Bacteria are among the simplest organisms in nature, but many of them can still talk to each other, using a chemical "language" that is critical to the process of infection. Sending and receiving chemical signals allows bacteria to mind their own business when they are scarce and vulnerable, and then mount an attack after they become numerous enough to overwhelm the host's immune system. This system, called "quorum sensing," is an interesting example of sophistication among microbes, says Helen Blackwell, an associate professor of chemistry at the University ...

Mammogram sensitivity depends on menstrual cycle

2010-12-07
SEATTLE—Try to schedule your screening mammogram during the first week of your menstrual cycle. It might make breast cancer screening more accurate for pre-menopausal women who choose to have regular mammograms. This recommendation comes from an article published online December 3 in Radiology by Diana Miglioretti, PhD, a senior investigator at Group Health Research Institute. Dr. Miglioretti and her co-authors are working on an issue at the heart of recent controversies about breast cancer screening mammograms. In November 2009, new recommendations—including that women ...

Metabolism models may explain why Alzheimer's disease kills some neuron types first

Metabolism models may explain why Alzheimers disease kills some neuron types first
2010-12-07
Bioengineers from the University of California, San Diego developed an explanation for why some types of neurons die sooner than others in the brains of people with Alzheimer's disease. These insights, published in the journal Nature Biotechnology on November 21, come from detailed models of brain energy metabolism developed in the Department of Bioengineering at the UC San Diego Jacobs School of Engineering. The Alzheimer's insights demonstrate how fundamental insights on human metabolism can be gleaned from computer models that incorporate large genomic and proteomic ...

Fewer guessing games for lung cancer patients

2010-12-07
Reston, Va. — A study published in the December issue of The Journal of Nuclear Medicine identified positron emission tomography/computed tomography (PET/CT) scans as a potentially useful tool for predicting local recurrence in lung cancer patients treated with radiofrequency ablation (RFA). RFA, which uses localized thermal energy to kill cancer cells, is increasingly used as an alternative treatment for patients unable to undergo surgery or other therapies to treat lung cancer. "This study reinforces the utility of 18F-FDG-PET imaging in cancer detection and follow-up ...
