Shipwrecks teem with underwater life, from microbes to sharks

When ships sink, they add artificial structures to the seafloor that can quickly become diverse, ecologically important underwater communities.

The nose knows: How microbiomes and the smells they produce help shape behaviour in bugs, birds, beasts and humans

The microbiome and its signature smells are crucial for most organisms, whether human, insect or plant. The silent signals sent by the microbiome are essential communications that influence behaviour.

E. coli is one of the most widely studied organisms – and that may be a problem for both science and medicine

Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.

Do you crush microbes when you step on them?

You can squash small bugs by stepping on them, but can you crush even tinier microorganisms like viruses and bacteria? It turns out that you’d need to apply a lot of pressure.

The melting Arctic is a crime scene. The microbes I study have long warned us of this catastrophe – but they are also driving it

To fully understand the extent of climate-related dangers the Arctic – and our planet – is facing, we must focus on organisms too small to be seen with the naked eye.
Antimicrobial resistance is now a leading cause of death worldwide due to drug-resistant infections, including drug-resistant strains of tuberculosis, pneumonia and Staph infections like the methicillin-resistant Staphylococcus aureus shown here. (NIAID, cropped from original)

Removing antimicrobial resistance from the WHO’s ‘pandemic treaty’ will leave humanity extremely vulnerable to future pandemics

Drug-resistant microbes are a serious threat for future pandemics, but the new draft of the WHO’s international pandemic agreement may not include provisions for antimicrobial resistance.

Reconstructing ancient bacterial genomes can revive previously unknown molecules – offering a potential source for new antibiotics

Ancient microbes likely produced natural products their descendants today do not. Tapping into this lost chemical diversity could offer a potential source of new drugs.
