Chimpanzees recognise one another from their rear ends
It is important for social animals to be able to recognise one another quickly. Humans are able to recognise each other immediately from their faces. Faces are also important for chimpanzees, but a new study by neuropsychologist Mariska Kret in PLOS ONE shows that the animals' buttocks also play a…

Islam and law
Systematic investigations into religious precepts, worldly rules of law and legal practices in the Muslim world show clearly how these societies deal with justice and injustice. Sharia, the Islamic ‘legal system’, plays an important role in this context.

Self-folding metamaterial
The more complex the object, the harder it is to fold up. Space satellites often need many small motors to fold up an instrument, and people have difficulty simply folding up a roadmap. Physicists from Leiden and Amsterdam have now designed a structure that folds itself up in several steps. Publication…

Elastic Leidenfrost Effect enables soft engines
Water droplets float in a hot pan because of the so-called Leidenfrost effect. Now physicists have discovered a variation: the Elastic Leidenfrost effect. It explains why hydrogel balls jump around on a hot plate making high pitched sounds. Publication in Nature Physics on July 24.

Bacterial Chromatin
The relative simplicity of the bacterial cell, short generation times and well defined and inexpensive culturing conditions have significantly contributed to our understanding of many complex biological systems. Yet the workings of the bacterial genome, seemingly impossibly compressed within a tiny…

Protein condensates and fiber formation
Some species of proteins which can form liquid-like condensates, also exhibit growth into fibers (or fibrils). One particularly interesting set of such proteins are those that are associated with neurodegeneration in which the fiber growth may be related to the pathological fibrils observed in disea…
