Marine extremophiles: The basal level of the food chain

In nutrient-poor deep-sea sediments, microbes belonging to Archaea have outcompeted bacterial microorganisms for millions of years. Efficiently scavenging dead cells makes them the basal producers in the food chain.

Fabrics that protect against chemical warfare agents

A new coating for textile fibers shows promise for efficiently capturing toxic industrial chemicals and chemical warfare agents under real-world conditions, including high humidity. The research could lead to improved masks ...

A microbe's membrane helps it survive extreme environments

Within harsh environments like hot springs, volcanic craters and deep-sea hydrothermal vents – uninhabitable by most life forms – microscopic organisms are thriving. How? It's all in how they wrap themselves.

New transmission microscope for low-energy electrons

Physicist Daniël Geelen (Leiden University) has developed a new microscope that uses low-energy electrons. Those are less harmful to biological and organic materials. Geelen defended his Ph.D. thesis on May 31st.

Better identification of microscopic fossils

Blue-green algae are one of the oldest organisms in the world and have an important role to play in many ecosystems on Earth. However, it has always been difficult to identify fossils as blue-green algae without any trace ...
