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. In a study published today in the British Medical Journal, an international team led by Imperial College London and KU Leuven, Belgium describe a new test, called ADNEX, which can discriminate ...

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. The trial included 200 obese adults (BMI 30–45kg/m²) who were randomly assigned to either a 12-week rapid weight loss programme (average weight ...

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. Using 3D imaging technologies, Dr Chin Wee Tan and Professor Tony Burgess from the Walter and ...

Magnetic mirrors enable new technologies by reflecting light in uncanny ways

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. As reported today in The Optical Society's (OSA) new high-impact journal Optica, scientists have demonstrated, for the first time, a new type of mirror that forgoes a familiar shiny metallic surface and instead reflects infrared light by using an unusual magnetic property of a non-metallic metamaterial. By placing nanoscale antennas at or ...

Plant communities produce greater yield than monocultures

Although monocultures can be cultivated efficiently, they are anything but sustainable: environmental damage to soil and water caused by monoculture cultivation is becoming increasingly evident. Despite their disadvantages, however, monocultures remain the principal crop form and are regarded as the sole possibility of achieving higher yields in plant production – quite wrongfully, finds Bernhard Schmid, an ecology professor at the University of Zurich, who advocates a novel form of agriculture and forestry. After all, a new study carried out by PhD student Debra ...

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. "With the increasing numbers of people with mild TBI in the community, it's crucial for nurses to make this a part of assessment for early recognition and intervention," ...

Some rice-based foods for people with celiac disease contain relevant amounts of arsenic

Rice is one of the few cereal grains consumed by people with celiac disease, as it does not contain gluten. However, it can have high concentrations of a toxic substance – arsenic – as revealed by the analyses of flour, cakes, bread, pasta and other foods made with rice, conducted by researchers from the Miguel Hernández University of Elche, Spain. The European Union is working to establish the maximum quantities of arsenic in these products. Celiac disease affects almost 1% of the population of the western world, a group which cannot tolerate gluten ...

Rivers flow differently over gravel beds, study finds

CHAMPAIGN, Ill. — River beds, where flowing water meets silt, sand and gravel, are critical ecological zones. Yet how water flows in a river with a gravel bed is very different from the traditional model of a sandy river bed, according to a new study that compares their fluid dynamics. The findings establish new parameters for river modeling that better represent reality, with implications for field researchers and water resource managers. "The shallow zones where water in rivers interacts with the subsurface are critical environmentally, and how we have modeled ...

Oh brother! Having a sibling makes boys selfless

A new study brings good news to all the brothers out there: Having a sibling is just as good for you as it is for your sister. That's surprising to family scholars because boys typically report that they benefit less than girls from peer relationships. "In our study, most relationships were not as important for boys as they were for girls," said study co-author Laura Padilla-Walker. "But the sibling relationship was different – they seemed to report relying on sibling affection just as much as girls do. It's an area where parents and therapists could really help ...

Older adults satisfied with aging more likely to seek health screenings

ANN ARBOR—Adults over 50 who feel comfortable about aging are more proactive in getting preventive health care services, a new University of Michigan study found. Sometimes, the older population does not visit their doctor because they believe that physical and mental declines typify old age, says Eric Kim, a U-M doctoral student in clinical psychology. They think that lifestyle changes will not make a difference, making them less likely to seek preventive care. This is not true and also not a healthy mindset, he says.

Camargue flamingos starved in freezing conditions in 1985 and 2012 mass mortalities

1985 was one of the worst years in living memory for the flamingo population of the Camargue, France. Over a 15 day period in January, temperatures plummeted, the lagoons, ponds and salt pans where the birds feed froze and by the time the Arctic blast had loosened its grip, almost one third of the population was dead. 'The 1985 mass-mortality shocked a generation of conservationists,' says David Grémillet from the CEFE-CNRS, France.
