The Sydney Harbour is renowned as a beautiful landmark straddling our thriving city  but a new study has shown it is also a source of significant carbon emissions, which requires careful management as the city is poised to double its population by the end of the century.

That is the message of new research that has quantified CO2 emissions from the Harbour for the first time – found to be 1000 tonnes annually – equivalent to the pollution from about 200 cars.

Studying the food poisoning bacteria E. coli may have led scientists to discover a new and improved tool to detect cancer.

In a collaborative research project, scientists from Griffith University’s Institute for Glycomics, the University of Adelaide and University of Queensland have detailed their findings in a new paper published in Scientific Reports.

The next time you walk down the produce aisle of your grocery store, you may want to reach for red onions if you are looking to fight off cancer.

In the first study to examine how effective Ontario-grown onions are at killing cancer cells, U of G researchers have found that not all onions are created equal.

Millions of people worldwide use back pain apps, however no independent guidance is available to help consumers identify which ones are safe and of high quality, a new study has found.

Researchers at Umeå University have developed a model that uses seasonal weather data from satellite images to accurately predict outbreak of malaria with a one-month lead time. With a so-called GAMBOOST model, a host of weather information gathered from satellite images can be used as a cost-effective disease forecasting model, allowing health officials to get ahead of the malaria infection curve by allocating resources and mobilizing public health responses. The model was recently described in the journal Scientific Reports, a Nature Research publication.

The world may be closer to knowing why Ebola spreads so easily thanks to a team of researchers from Tulane University and other leading institutions who discovered a new biological activity in a small protein from the deadly virus. The team’s findings were recently published in the Journal of Virology.

Ophir Klein is growing teeth, which is just slightly less odd than what Jeffrey Bush is growing – tissues that make up the face. Jason Pomerantz is growing muscle; Sarah Knox is growing salivary glands; and Edward Hsiao is printing 3-D bone using a machine that looks about as complex as a clock radio.

Together, these members of the UC San Francisco faculty are cultivating organs of the craniofacial complex – the skull and face – which too often go terribly wrong during fetal development. Deformities of these bones or soft tissues, the most common of birth defects, can cut life short by blocking the airway or circulation. Or they can disfigure a face so profoundly that a child struggles to see, hear, or talk. Perhaps most painful of all, such deformities render children physically other, potentially leading to a lifetime of corrective surgeries and social isolation.

At least 100,000 military veterans who served in the 1990-1991 Gulf War were exposed to chemical weapons, released into the air after the United States bombed an ammunition depot in Khamisiyah, Iraq. Today, many are still suffering from Gulf War Illness, a mysterious, multi-symptom disease that experts believe is linked to organophosphate nerve agents sarin and cyclosarin.

As the summer months approach, most people turn to thoughts of sunshine, outdoor barbecues and destination trips. Yet travelers often are greeted by detours, lane closures and delays for road repairs that generally are reserved for warmer weather. Researchers at the University of Missouri have studied systems to alleviate inevitable backups and delays. Researchers found that using variable speed limits in construction zones may ease congestion, reduce crashes and make work zones safer for both workers and travelers nationally.

With assistance from the Missouri Department of Transportation, Praveen Edara, associate professor of civil and environmental engineering in the MU College of Engineering, tested the use of variable advisory speed limit (VASL) systems and the effect they may have on lessening congestion and reducing rear-end and lane-changing accidents on a fairly dangerous stretch of I-270, a major four-lane highway in St. Louis.

The use of immunotherapy to treat cancer is celebrating its first successes – but there are still many knowledge gaps in the underlying mechanisms of action. In a study of mice with soft tissue tumours, ETH researchers have now shown how endogenous killer cells track down the tumours with the help of dormant viruses.
