This month, we’re bringing you a real highlight from our Annual Conference in Edinburgh: a live discussion about the state of microbiome research.

A panel of experts gave their views on whether microbiome research is an opportunity, or whether it’s been over-hyped.

It was a really lively event with a great audience, and it was chaired by our very own Dr Benjamin Thompson.

Panelists:
Prof Julian Marchesi, Imperial College London
Prof Jim Prosser, University of Aberdeen
Dr Lindsay Hall, University of East Anglia
Dr Thorunn Helgason, University of York

Have you ever wondered about the kinds of microbes that are present in your kitchen? In the fruit bowl or the fridge, on your chopping boards or cleaning cloths?

Good Germs Bad Germs is a citizen science project from the University of Oxford, allowing people to experiment on the microbial life in their kitchens and to visualise the results.

This month, we went to Oxford to visit one of the households taking part in the project, and spoke to researchers Dr Jamie Larimer and Dr Beth Greenhough about they've found.

In 2008, researchers from Google announced that they could predict outbreaks of the flu up to two weeks before the US authorities, by monitoring people's Google search behaviour.

The algorithm tracked searches for flu symptoms and remedies, which would increase in the build-up to an outbreak. Flu is a serious disease that can cause up to half a million deaths each year – so Google flu trends caused a lot of excitement in the field when it emerged.

But for all the hype, it didn't actually work. In the end, Google flu trends failed pretty badly. So what went wrong?

This month, we speak to public health experts and computer scientists to find out, and learn how the field of 'Digital Epidemiology' has moved on to successfully track disease outbreaks online.

We hear from Professor Guy Poppy and Dr Sian Thomas from the Food Standards Agency in the UK about a tool to track norovirus using tweets, and all the #vomit that entails.

And we speak to Professor Alessandro Vespignani from Northeastern University in the US about how Twitter can help to build virtual synthetic worlds where researchers can model the spread of flu.

Air pollution is a big problem. It's our single largest environmental health risk, and causes an eighth of all global deaths worldwide.

We know that air pollution increases respiratory diseases and the risk of infections like pneumonia. But now, new research suggests air pollution may alter the properties of bacteria themselves, in some potentially worrying ways.

This month, we spoke to Dr Julie Morrissey from the University of Leicester about the study, and what it means for our health.

Earlier this month, the Microbiology Society hosted our Annual Conference 2017 in Edinburgh. While we were there, we managed to catch up with just a few of the researchers presenting posters and giving talks.

First up, we spoke to Kirsty Fraser from Heriot-Watt University about a weird protist pathogen wreaking havoc on golf courses.

Next, Dr Terry McGenity from the University of Essex told us about microbes that can survive for millennia trapped inside salt crystals.

Finally, we spoke with Saskia Rughöft from the Molecular Microbial Ecology Group at the University of Tubingen. Saskia is researching the impact of oil spills and cleanup chemicals on microbes in the ocean.

In 1901, Captain Robert Falcon Scott led a team of men on the Discovery Expedition to explore the mysteries of Antarctica.

The expedition is famous for its scientific legacy, including the discovery of snow-free valleys, emperor penguin colonies and the location of the South Magnetic Pole.

But the team also brought back some mysterious life forms living at the bottom of a lake. It took nearly 60 years for scientists to work out what they really were: cyanobacteria.

Dr Anne Jungblut is a microbiologist studying cyanobacteria today at the Natural History Museum. In this episode, we visit the museum to learn more about these microbes, and see the very samples that Scott’s team brought back over 100 years ago….

Everyone knows the story of the Trojan horse.

The Greeks, in a war against the Trojans, hid some soldiers inside a giant wooden horse and left it outside the city of Troy. Thinking that they’d won, the Trojans dragged the horse inside the city walls. Later that night, the Greek soldiers crept out and sacked Troy from the inside, winning the war.

Our story this month is also set in ancient Troy, and has a few things in common with this mythical tale. There’s no great battle, but there is death. And instead of soldiers hiding inside a wooden horse, it involves some unexpected microbes hiding inside the chest of a woman who died 800 years ago.

We spoke to Caitlin Pepperell from the University of Wisconsin–Madison about her research into this woman’s story, and the remarkable molecular portrait of her life and death that scientists were able to piece together.

What’s it like to travel right down to the bottom of the ocean?

Deep sea microbiologist Julie Huber should know. Her group, at the Marine Biological Laboratory in Massachusetts, USA, is trying to uncover more about the microbes living in the deepest darkest depths of the ocean. But that’s not all – there are even microbes living thousands of metres beneath the ocean floor itself, within the rocks and sediment.

This is an environment that couldn’t be more different to our world on land – no light, huge pressures, underwater volcanoes and hardly any nutrients. So what kind of microbes do we see living there, and how do they manage to make a living?

What gives beer its taste? Why do some ales taste of berries, bananas or chocolate?

A big part of the answer is the type of yeast used to ferment it. There are hundreds of different strains that brewers can use to make beer, and many of them can be found at the National Collection of Yeast Cultures in Norwich.

We went for a pint with scientists from the NCYC to find out how different yeasts affect the taste of ales, and learn about their research to find strains that can produce new and better beers.

When pathogenic viruses pass from their animal reservoir into humans – known as ‘spillover events’ – the consequences can be severe. For example, it is thought that the West African Ebola outbreak began with an 18-month-old child in Guinea contracting the virus from a wild animal.

To prevent future disease epidemics, we need a better understanding of the nature of spillover events, and the viruses involved in them. In this month’s podcast, we spoke to Professor Jonna Mazet, Director of the One Health Institute at the University of California, Davis. Jonna is also the Global Director of PREDICT, an ambitious project that is trying to identify any pathogens that might pose a threat to human health, and working to build capacity in areas of the world that are at risk of disease emergence.
