Manx shearwaters marry for life and share the incubation and feeding of their single chick. Dr Keith Hamer of Leeds University’s School of Biology has discovered that males consistently provide more food than their wives, but it’s not because they’re better parents – they just don’t listen.
By dangling microphones into burrows of nesting shearwaters, Dr Hamer and Cardiff University colleagues Petra Quillfeldt and Juan Masselo found differences in the way shearwaters respond to the begging calls of their chick.
Dr Hamer said: “We found female behaviour depends on the intensity of the chick’s begging, with mothers of hungry chicks returning very frequently, while those of well-fed chicks stay away for up to eight days. Males return to the nest at least once every four days, bringing back food with predictable regularity, regardless of the chick’s cries.”

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
