But solar panels and wind turbines can only generate power when the sun shines and a breeze is blowing. What happens at night or when the weather is calm?

The microorganisms living in, on, and around us, collectively known as the microbiome, produce metabolites that affect our health. Some of these molecules are essential for our wellbeing, while others can harm us. Colibactin is an example of a toxin, produced as part of microbial warfare, which induces double-stranded breaks in the DNA of cells in the intestinal epithelium and is correlated with higher incidences of diseases such as colorectal cancer.

Bacteria producing colibactin must protect their own DNA, so they assemble a non-toxic precursor (precolibactin) in their...

What if emergency medical personnel could treat a desperately ill patient in need of oxygen with a simple injection instead of having to rely on mechanical ventilation or rush to get them onto a heart-lung bypass machine?

A new approach to transporting gases using a class of materials called porous liquids represents a big step toward artificial oxygen carriers and...

CCB researchers have developed an environmentally friendly mechanism to enable solid-state cooling with two-dimensional perovskites. Their findings are described in a new study in Nature Communications.
