Scientists from CSIRO's Food Futures Flagship have made a breakthrough in efforts to extend the sensory range of 'electronic noses' (e-noses) by developing a system for comparing their performance against the much-superior nose of the common house fly.

"Although e-noses already have many uses – such as detecting spoilage in the food industry and monitoring air quality – they are not as discriminating as biological noses," according to CSIRO scientist, Dr Stephen Trowell.

Men who have a regular, ongoing relationship with a health care provider are more likely to receive prostate cancer screening and less likely to be diagnosed with advanced prostate cancer, regardless of their race, according to a University of North Carolina study published in the current issue of the journal Cancer.

A new urine test developed with funding from the Wellcome Trust will allow doctors to diagnose Chlamydia infection in men within the hour, improving the ability to successfully treat the infection on the spot and prevent re-transmission.

Chlamydia, caused by the bacterium Chlamydia trachomatis, is the most common sexually-transmitted bacterial infection in the UK, particularly amongst sexually active men and women aged 16-24 years.

With the rapid-fire release of data, studies presented at medical conferences in the age of instant information can have an almost immediate impact on patient treatment, said Matthew T. Roe, M.D., M.H.S., lead author of the study and associate professor of medicine at Duke University Medical Center and at the Duke Clinical Research Institute in Durham N.C.

"We were interested in whether practice patterns changed after the presentation of these studies," he said. "That's indeed what we showed."

WASHINGTON, D.C., July 28, 2009 -- The tubes that power X-ray machines are shrinking, improving the clarity and detail of their Superman-like vision. A team of nanomaterial scientists, medical physicists, and cancer biologists at the University of North Carolina has developed new lower-cost X-ray tubes packed with sharp-tipped carbon nanotubes for cancer research and treatment.

TEMPE, Ariz. – We could soon see the potential of laser technology expand dramatically.

Ways to make lasers smaller are being discovered through collaborative efforts of researchers at Arizona State University and Technical University of Eindhoven in the Netherlands. The work opens up possibilities for using nanoscale lasers to significantly improve the performance of computers and speed up Internet access .

WASHINGTON -- With a sustained national commitment, the United States could obtain substantial energy-efficiency improvements, new sources of energy, and reductions in greenhouse gas emissions through the accelerated deployment of existing and emerging energy technologies, according to AMERICA'S ENERGY FUTURE: TECHNOLOGY AND TRANSFORMATION, the capstone report of the America's Energy Future project of the National Research Council, the operating arm of the National Academy of Sciences and National Academy of Engineering.

The online logic puzzle called FunSAT, could help integrated circuit designers select and arrange transistors and their connections on silicon microchips.

Designing chip architecture for the best performance and smallest size is an exceedingly difficult task that's outsourced to computers these days. But computers simply flip through possible arrangements in their search. They lack the human capacities for intuition and visual pattern recognition that could yield a better or even optimal design. That's where FunSAT comes in.

Washington, DC – A new study by researchers at the Georgetown's Lombardi Comprehensive Cancer Center finds a higher level of common household pesticides in the urine of children with acute lymphoblastic leukemia (ALL), a cancer that develops most commonly between three and seven years of age. The findings are published in the August issue of the journal Therapeutic Drug Monitoring.

Researchers caution that these findings should not be seen as cause-and-effect, only that the study suggests an association between pesticide exposure and development of childhood ALL.

In light of health care reform measures, Rush University Medical Center has launched a study of its program to help older adults transition from hospital to home.

The goal of the study is to determine whether the program, first implemented two years ago, succeeds in reducing readmissions within 30 days for seniors. If it does, it could serve as a model for hospitals across the country that are seeking ways to lower their rates of readmission.
