It is very difficult to predict whether a cancer drug will help an individual patient: only around one third of drugs will work directly in a given patient. Researchers at the Heinz Nixdorf Chair for Medical Electronics at ...

Mother bats expert at saving energy

In order to regulate their body temperature as efficiently as possible, wild female bats switch between two strategies depending on both the ambient temperature and their reproductive status. During pregnancy and lactation, ...

As oceans warm, large fish struggle

Warming ocean waters could reduce the ability of fish, especially large ones, to extract the oxygen they need from their environment. Animals require oxygen to generate energy for movement, growth and reproduction. In a recent ...

The oxygen content of the ocean may be subject to frequent ups and downs in a very literal sense—that is, in the form of the numerous sea creatures that dine near the surface at night then submerge into the safety of deeper, ...

Jumping snails leap over global warming

Snails in the Great Barrier Reef literally jump for their life to avoid predators. But will they be able to maintain these life-saving jumps, with rising sea temperatures? A new study, to be presented at the Society for Experimental ...
