Did hepatitis C virus originate in horses?

About 2% of the world’s population is chronically infected with hepatitis C virus (HCV). This enveloped, positive-strand RNA virus was discovered in 1989, but serological and phylogenetic evidence indicates that it has been infecting humans for hundreds of years, perhaps as long ago as the 14th ...

To combat the overuse of antibacterials, stop using the absolutely terrible word, "antibiotic"

There are many reasons why bacteria evolve resistance to antibacterials, but one of the preventable reasons is the over-prescription of antibacterials to patients who don't have bacterial infections. But how to get people to stop asking for antibacterials? My suggestion is to stop using the wor... Read More

The Science Behind Honey’s Eternal Shelf Life

Modern archeologists, excavating ancient Egyptian tombs, have often found something unexpected amongst the tombs’ artifacts: pots of honey, thousands of years old, and yet still preserved. Through millennia, the archeologists discover, the food remains unspoiled, an unmistakable testament to the... Read More

Influenza H5N1 x H1N1 reassortants: ignore the headlines, it’s good science

Those of you with an interest in virology, or perhaps simply sensationalism, have probably seen the recent headlines proclaiming another laboratory-made killer influenza virus. From The Independent: ‘Appalling irresponsibility: Senior scientists attack Chinese researchers for creating new strain... Read More

Bespoke microbiome therapy to manage plant diseases

In this paper we describe the perspective of following the achievements in medicine, where gut microbiome transplants are proving to be a powerful method to overcome several gastrointestinal disorders and many other physiological problems, to possible solve diseases in plants. There is strong si... Read More

Marine Microbiology, Twitter Friends, and Shrunken Coffee Cups

In this blog entry, I discuss how marine microbiology is fascinating to students, as well as the topic leading me (via social media) to other marine microbiologists. One of those marine microbiologists made me a "shrunken coffee cup" (shrunken due to being carried below a kilometer of depth on ... Read More

Blastocystis Parasite Blog

Our bodies are made up by cells containing our own DNA. Plus 10 times as many with foreign DNA. The bacteria found on our skin, and inside our organs (intestine, vagina, mouth, nose, etc.) are referred to as our “microbiome”, outnumber our own cells by 10 to 1, and make up a vital organ with ind...

How many viruses on Earth?

How many different viruses are there on planet Earth? Twenty years ago Stephen Morse suggested that there were about one million viruses of vertebrates (he arrived at this calculation by assuming ~20 different viruses in each of the 50,000 vertebrates on the planet). The results of a new study s... Read More

Freshman Biology Creative Projects!
