Animal-testing alternatives will require a cultural change in research institutions

Whether in tooth enamel or in nanomaterials made of silicon, the orientation of tiny internal structures often determines the properties of a material. A new X-ray method can even make this nano-order visible when the structures are actually too small to be imaged directly. The method was developed by an international team led by the Helmholtz Center Hereon, and it opens up new possibilities to investigate materials and biological structures. The research is published in the journal Light: Scien

To the untrained eye, they look like blobs blotching the otherwise smooth surface of rod-like bacteria. But if you ask a microbiologist about "cellulosomes," they will likely tell you that those blobs are actually sophisticated cellulolytic machines.

Carbon credits bought by companies to offset their emissions really have reduced deforestation, but not by as much as credit developers claim, according to a rigorous analysis

Work songs, musical pieces designed to be performed or sung while working, have been widely documented across various cultures and in different historical periods. For instance, people in different nations have been known to sometimes sing together while rowing, sailing, harvesting crops or building structures.
