MADISON — A University of Wisconsin-Madison biomedical engineer and colleagues have developed a method that, applied in MRI scans of the breast, could spare some women with increased breast cancer risk the pain and stress of having to endure a biopsy of a questionable lump or lesion.

The universal technology will give radiologists greater confidence in visually classifying a lesion as malignant or benign.

Amsterdam, The Netherlands: Ultra-fast freezing of ovarian tissue from women who have lost their fertility as a result of cancer treatment can lead to it being used in transplants with the same success rate as fresh tissue, a researcher told the 25th annual conference of the European Society of Human Reproduction and Embryology today (Monday 29 June).

Between the 1932 and 2008 Olympic Games, world record times of the men's 100m sprint improved by 0.6 seconds due to improved training techniques and technological advances. Imagine if this improvement could be achieved by a simple change in diet. Scientists at the Research Institute of Wildlife Ecology in Austria have managed to achieve an equivalent feat in mice fed on a diet high in polyunsaturated fatty acids.

High ozone conditions cause a 30% decrease in yield and an increase in the concentration of a group of toxic compounds within oilseed rape plants. Combined with the results of previous studies which have shown a decrease in oil, protein and carbohydrate content of oilseed rape seeds in high ozone, these results (to be presented at the Society for Experimental Biology Annual Main Meeting in Glasgow on 29th June 2009) could signal a significant income loss for farmers and an indirect effect on human health and the safety of food in future climates.

The two leading bodies representing GPs in the UK have backed a call by the Wellcome Trust for clearer guidance for GPs to ensure medical records can be safely used in research.

Patient records in general practice surgeries are a unique resource of information which can help medical researchers improve their understanding of disease, develop potential new treatments and improve patient care. The increasing use of electronic records should make it easier for researchers to use this information.

Amsterdam, The Netherlands: Complications in early pregnancy or in previous pregnancies can predict thelikelihood of further problems in current or subsequent pregnancies, according to research carried out by aninternational group of experts.

Kansas State University researchers are studying the effects of integral bridge expansion resulting from heat to make these types of bridges a more viable alternative.

The recent increase in area burned by wildfires in the Western United States is a product not of higher temperatures or longer fire seasons alone, but a complex relationship between climate and fuels that varies among different ecosystems, according to a study conducted by U.S. Forest Service and university scientists. The study is the most detailed examination of wildfire in the United States to date and appears in the current issue of the journal Ecological Applications.

For those who are caring for elderly parents, peace of mind is hard to come by. And, for their parents, dignity is hard to retain. But a team of University of Houston researchers hopes to ease worries and frustrations by designing an affordable in-home health-monitoring system that will notify caregivers, via smartphones or PDAs, if their loved ones need attention.

An emergency rule intended to reduce the number of deaths and injuries associated with Hawaiian air tours was followed by a 47 percent reduction in sightseeing crashes, according to a new study by researchers from the Johns Hopkins Bloomberg School of Public Health's Center for Injury Research and Policy.

PHILADELPHIA (June 25, 2009)—Reviewing the records of 577 breast cancer patients, Fox Chase Cancer Center researchers found that women with newly diagnosed breast cancer who receive a breast MRI are more likely to receive a mastectomy after their diagnosis and may face delays in starting treatment. The study demonstrates that, despite the lack of evidence of their benefit, routine use of MRI scans in women newly diagnosed with breast cancer increased significantly between 2004 and 2005, and again in 2006.

DURHAM, NC—According to a new study from researchers at Duke University, total knee arthroplasty (TKA) procedures performed in older patients with osteoarthritis of the knee result in long-term, significant improvement of physical functioning and motor skills when compared to patients who do not receive TKA.

MADISON - President Barack Obama's signature on a bill this week to grant the Food and Drug Administration (FDA) regulatory authority over tobacco was historic, and represents a step in the march to eliminate tobacco use in this country by 2047, two national tobacco experts said today (June 25).

In a review in Science, a University of Rochester Medical Center researcher sorts out the controversy and promise around a dangerous subtype of cancer cells, known as cancer stem cells, which seem capable of resisting many modern treatments.

The article proposes that this subpopulation of malignant cells may one day provide an important avenue for controlling cancer, especially if new treatments that target the cancer stem cell are developed and combined with traditional chemotherapy and/or radiation.

Stroke patients with obstructive sleep apnea (OSA) who undergo treatment with continuous positive airway pressure (CPAP) following their stroke may substantially reduce their risk of death, according to Spanish research to be published in the July 1 issue of the American Journal of Respiratory and Critical Care Medicine.
