How nanosized shrapnel from exploding fungal cells may impact us: from allergies to cloud formation

Invisible to the naked eye, we are almost always surrounded by small particles suspended in the air. They are known as atmospheric aerosols and can be made of directly emitted particles like dust, sea salt, and viruses; or formed in the atmosphere out of molecules... click to read more

A newly discovered (microscopic) global source of methane

The average temperature on Earth rose dramatically during the last century. This is due to human activity, which led to the increased atmospheric concentration of certain gases, typically called greenhouse gases. These gases increase the solar heat trapped by our planet. The greenhouse gas methane... click to read more

Ouch, that needle hurts! How some viruses inject their DNA

Bacteriophage T4 is one of the most common of the viruses that infects Escherichia coli (E. coli) bacteria that serve as the hosts. To accomplish this feat, phage T4 employs a fascinating nano-scale injection machine to first rupture the host's cell membrane and then inject... click to read more

A soil bacterium unmasks a human enzyme

Life, as we know it, exists thanks to membranes. As active functional barriers between a living cell and its environment, and between compartments within the cell, membranes ensure selective entry and exit of substances, energy generation, and the sending, receiving, and processing of signals essential... click to read more

Producing next-gen polymers out of antimicrobial-resistant superbugs

Bacteria survive in an array of environments, so they are constantly exposed to a wide variety of toxic molecules. To be able to survive in different environments, bacterial cells must be able to actively protect themselves from toxins. Often they do this by breaking down... click to read more
