A Monash University-led study has found that an unusual pairing of two commonly used antibiotics can kill and stop the spread of resistance in a highly drug-resistant bacterium, Pseudomonas aeruginosa, which can cause life-threatening bloodstream infections, pneumonia and meningitis.

Hiroshima University researchers use the previous 20 years of data to project what the currently implemented treatment and management strategy does for the HBV and HCV cases in 2050.

Every mechanical assembly produces acoustic emissions. Cranks, bearings, switches and far more make noise — the kind that can be heard and the kind that advanced technology can detect to determine the health of the mechanism. One area where this acoustic emission technology has not kept up, though, is for journal bearings: the support for rotating shafts in various machines, including transmission engines. Journal bearings depend on a film of oil surrounding the shaft to maintain operation. Should the oil become contaminated or some other mechanical failure occur, the entire mechanism can be at risk. Researchers have studied acoustic emissions for detecting mechanical failure since the 1950s and specifically for journal bearings since 1985. Now, an international team has pulled together the latest in the field to better understand how far it has come and what direction it should go.

Researchers from the EHU-University of the Basque Country have developed a robust protocol to detect the molecules involved in the metabolic reactions of sperm. The new method enables a detailed analysis to be made even with small samples, and the largest number of potential biomarkers identified to date to be detected; this advance could help to diagnose male infertility and develop future clinical solutions.
