Cadavers beat computers for learning anatomy

Cadavers beat computers for learning anatomy

EAST LANSING, Mich. --- Despite the growing popularity of using computer simulation to help teach college anatomy, students learn much better through the traditional use of human cadavers, according to new research that has implications for health care.

Cary Roseth, associate professor of educational psychology at Michigan State University, said the study suggests cadaver-based instruction should continue in undergraduate human anatomy, a gateway course to medical school, nursing and other health and medical fields.

Cryptic clues drive new theory of bowel cancer development

Cryptic clues drive new theory of bowel cancer development

Melbourne researchers have challenged conventional thinking on how the bowel lining develops and, in the process, suggested a new mechanism for how bowel cancer starts.

The researchers produced evidence that stem cells are responsible for maintaining and regenerating the 'crypts' that are a feature of the bowel lining, and believe these stem cells are involved in bowel cancer development, a controversial finding as scientists are still divided on the stem cells' existence.

WASHINGTON, Oct. 16—As in Alice's journey through the looking-glass to Wonderland, mirrors in the real world can sometimes behave in surprising and unexpected ways, including a new class of mirror that works like no other.

Scientists find ancient mountains that fed early life

Scientists find ancient mountains that fed early life

"Scientists have speculated that such a large mountain range must have been feeding the oceans because of the way life thrived and ocean chemistry changed at this time, and finally we have found it."

The discovery is earliest evidence of Himalayan-scale mountains on Earth.

"Although the mountains have long since washed away, rocks from their roots told the story of the ancient mountain range's grandeur," said co-researcher Professor Joerg Hermann.

New test can help doctors choose best treatment for ovarian cancer

Researchers have devised a new test to help doctors diagnose ovarian tumours and choose the most appropriate treatment.

Successful treatment depends in part on accurately identifying the type of tumour, but this can be difficult. As a result, many women with cancer are not sent to the right specialist surgeon, or those with a benign cyst may have a more serious operation than they need.

Slow and steady does not win the weight loss race

Led by Joseph Proietto, Sir Edward Dunlop Professor of Medicine at the University of Melbourne and Head of the Weight Control Clinic at Austin Health, the study also found that substantial weight loss is more likely to be achieved if undertaken rapidly.

"This randomised study highlights the urgent need for committees that develop clinical guidelines for the management of obesity to change their advice," he said.

New perspectives for development of an RSV vaccine

Respiratory Syncytial Virus causes severe respiratory tract infections and worldwide claims the lives of 160,000 children each year. Scientists at VIB and Ghent University have succeeded in developing a promising vaccination strategy to counteract this common virus infection.

Xavier Saelens (VIB/UGent): "We discovered a new vaccination strategy that paves the way for the development of a novel approach to vaccination against RSV, a virus that causes suffering in numerous small children and elderly people."

Mild traumatic brain injury can have lasting effects for families, reports the American Journal of Nursing

October 16, 2014 – Families of patients with mild traumatic brain injury (TBI) may expect them to return to normal quickly—after all, it's "just a concussion." But mild TBI can have a lasting impact on families as well as patients, according to a review in the November issue of American Journal of Nursing. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
