Early life built Earth's continents

Rewind Earth's story 3 or 4 billion years, to when life was emerging. The surface of our planet was starting to cool but still piping hot – possibly about 200 °C. Early, unstable continents may have been forming. Now imagine life doesn't emerge, and press play.

This is what a new computer mod... Read More

The Microbiome And The Future Of Artisanal Gastronomy

Earlier this week, the media caught the stinky wind of a rather unique art exhibit at the Dublin Science Gallery. Called SELFMADE, the installation featured a number of cheeses made by a variety of different bacteria. While this may not seem all that strange, the fact that the bacteria came fr... Read More

Gut microbiota and the evolution of species

Science Magazine has recently published a study carried out by Dr. Robert Brucker and Dr. Seth R. Bordenstein from Vanderbilt University in Nashville (USA) that seems to provide clues reinforcing the “hologenome theory of evolution”. This research suggests that the gut microbiome may have a fund... Read More

Virus killing bottlenose dolphins may be jumping species, report says

The Microbes Living in Our Bodies Were Probably Once Evil Pathogens

Like pretty much all multi-cellular organisms, humans enjoy the benefits of helpful bacteria. (As you may have heard, there are more bacteria in the human body than cells.) These mutualistic microbes live within the body of a larger organism, and, like any good long-term houseguest, help out the... Read More

Black silicon slices and dices bacteria

Originally discovered by accident in the 1980s, black silicon is silicon with a surface that has been modified to feature nanoscale spike structures which give the material very low reflectivity. Researchers have now found that these spikes can also destroy a wide range of bacteria, potentially ... Read More
