Energy is the currency of life. Eat more than you use and you store fat; use more than you eat and you won't last long. But understanding bioenergetics is more than just a matter of our waistlines; it is fundamental to life and the interactions of all living things with the environment. Understanding how organisms use energy is also key to the survival of many species during this time of dramatic change. How will altering wind patterns impinge on migrating birds? What sets the upper limits on the amount of energy that animals can produce? How can we combat metabolic syndrome and the obesity epidemic? These are fundamental biological questions that go well beyond the protein structures and reaction mechanisms that underpin bioenergetics. Fascinated by biological energy use, Raul Suarez at the University of California, Santa Barbara, USA, has drawn together a collection of review articles addressing the issue of bioenergetics from a wide range of perspectives, from the ecological to biomedical. ‘I wanted to come up with an issue that demonstrates the range of research activity that goes on and shows that this is a vibrant and exciting area of science,’ says Suarez. Teaming up with JEB Editor-in-Chief Hans Hoppeler to invite contributors from various backgrounds with an interest in bioenergetics, Suarez has drawn together a unique collection of review articles addressing ‘The Biology of Energy Expenditure’.

Craig Franklin launches our centenary celebrations

Editor-in-Chief Craig Franklin reflects on 100 years of JEB and looks forward to our centenary celebrations, including a supplementary special issue, a new early-career researcher interview series and the launch of our latest funding initiatives.
Looking back on the first issue of JEB

Journal of Experimental Biology launched in 1923 as The British Journal of Experimental Biology. As we celebrate our centenary, we look back at that first issue and the zoologists publishing their work in the new journal.

Mexican fruit flies wave for distraction

Dinesh Rao and colleagues have discovered that Mexican fruit flies vanish in a blur in the eyes of predatory spiders when they wave their wings at the arachnids, buying the flies time to make their escape.
