Lunar and solar eclipses make animals do strange things

For most animals, the structure of their day—and indeed their year—depends on the light-dark cycle. These regular and rhythmic cycles in the length of days tell animals when they should be foraging, when they should be ...

Star Tau Boo's baffling magnetic flips

(Phys.org) —The first observations of the complete magnetic cycle of a star other than the Sun are proving a puzzle to astronomers. Tau Boötis, known as Tau Boo (τ Boo), is a yellowish star that is a little brighter than ...

A quantum simulator for magnetic materials

Physicists understand perfectly well why a fridge magnet sticks to certain metallic surfaces. But there are more exotic forms of magnetism whose properties remain unclear, despite decades of intense research. An important ...

New insights into placebo effect

(Phys.org)—Mathematical models developed by scientists at the University of Bristol are providing new insights into why the placebo effect exists and when it should occur. Their research is published today in the journal ...

First experiment at the ALBA synchrotron

The ALBA Synchrotron Light Facility has begun to function as a research tool. Of the seven experimental beamlines scientists can use to analyse their samples, the first which has begun to work is the BOREAS line, addressed ...

Graphite mimics iron's magnetism

Researchers of Eindhoven University of Technology and the Radboud University Nijmegen in The Netherlands show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for ...
