A common, humble field bug is spreading a disease that has already infected millions of olive trees in Italy.

Olive and citrus fruit crops throughout the Mediterranean are threatened, yet there has been a collective failure to recognize the danger and take decisive action.

Rolling Stone’s retraction of an incendiary article about an alleged gang rape on the campus of the University of Virginia certainly deserves a place in the pantheon of legendary journalism screw-ups. It is highly unusual – although not unprecedented – for a news organization to air its dirty laundry so publicly.

It’s not often that medievalists get as excited as they have been over the revival of a medieval remedy for eye conditions involving garlic, onions, wine and ox gall, prepared in a bronze vessel. The concoction, mixed up by a team from Nottingham University, appeared to show promising results in the battle against MRSA. It didn’t kill it all, but it apparently killed 90%. This has revived enthusiasm for trawling ancient texts for the solutions to modern problems.

Take this quick medical pop quiz: which of the following conditions would you prefer to have during your next stay in hospital? A. Staphylococcus aureus (golden staph) bloodstream infection; or B. a heart attack?

I am guessing most non-medical readers voted for the Staph option and, if my experience is anything to go by, the majority of medical readers will have also made a microbial choice.

Science is considered a source of truth and the importance of its role in shaping modern society cannot be overstated. But in recent years science has entered a crisis of trust.

The results of many scientific experiments appear to be surprisingly hard to reproduce, while mistakes have highlighted flaws in the peer review system. This has hit scientific credibility and prompted researchers to create new measures in order to maintain the quality of academic research and its findings.

How we get along as siblings is a deeply personal issue and profoundly effects our lives as individuals. It’s an issue that crosses cultures and economies, levels of class and fame.

This point was reinforced to me when I did an interview on the Today Show about the importance of sibling conflict. Co-host Karl Stefanovic torpedoed in at the end and dismissed everything I was saying as nonsense. He made it clear that his lifelong domination of his younger brother, Peter, is perfectly normal and acceptable. If anything he seemed to be very proud of it.
