With global goals set on transitioning away from fossil fuels, fuel cells stand out as a promising carbon-free energy source. Comprising an anode and a cathode separated by an electrolyte, fuel cells convert the chemical energy of fuel directly into electricity. The anode receives the fuel, while an oxidant, typically oxygen from the air, is introduced at the cathode. In a hydrogen fuel cell, hydrogen undergoes oxidation at the anode, producing hydrogen ions and electrons. The ions move through the electrolyte to the cathode, and electrons flow through an external circuit, generating electricity. At the cathode, oxygen combines with the hydrogen ions ...

Researchers at the Francis Crick Institute have shed light on how cancer cells survive in the first few hours after being cut off from a supply of oxygen. Published today in The EMBO Journal, this finding could one day help to prevent cancer from becoming resistant to therapy. A major use of oxygen by cells is for energy production. When oxygen supplies are low, most cells can survive because they adapt, by changing which proteins they make, to produce energy through different processes than in normal oxygen levels. This is coordinated by a protein called HIF1α, which turns on the activity of genes. Although HIF1α ...
