How can we find novel natural products from Actinomycetes that act as growth modulators on mammalian cells? Can we harvest and develop the potential of these novel compounds for industrial and medical biotechnology?

Leiden archaeologists investigate how people in the past impacted their environment. Together with scientists, environmental scientists, and humanities experts, they use this information to draw conclusions about the present – and show what we can learn from it for the future.

Morphometric and morphological differences have been used extensively in the past to study domestication of the wolf and the origin of dogs. Certainly before genetic testing was performed, these methods were the only means to diverge both groups. But still now, when aDNA cannot be extracted, morphometry…

These objects therefore provide unique insights into the built environment of sanctuaries at this important Greek colony in Sicily. This research's multi-disciplinary…

Like any language, the natural sign languages of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that sign languages make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…
