Most research looking at the impact of climate change on human life has focused on how extreme weather events affect economic and societal health outcomes on a broad scale. Yet climate change may also have a strong influence on fundamental daily human activities— including a host of behavioural, psychological, and physiological outcomes that are essential to well-being. In a study published on May 20 in the journal One Earth, investigators report that increasing ambient temperatures negatively impact human sleep around the globe. The team says their findings suggest that by the year 2099, suboptimal temperatures may erode 50–58 hours of sleep per person per year. In addition, they found that the temperature effect on sleep loss is substantially larger for residents from lower income countries as well as in older adults and females.

A team of microbiologists from Goethe University Frankfurt has succeeded in using bacteria for the controlled storage and release of hydrogen. This is an important step in the search for carbon-neutral energy sources in the interest of climate protection. The fight against climate change is making the search for carbon-neutral energy sources increasingly urgent. Green hydrogen, which is produced from water with the help of renewable energies such as wind or solar power, is one of the solutions on which hopes are pinned. However, transporting and storing the highly explosive gas is difficult, and researchers worldwide are looking for chemical and biological solutions. A team of microbiologists from Goethe University Frankfurt has found an enzyme in bacteria that live in the absence of air and bind hydrogen directly to CO₂, in this way producing formic acid.
