Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

‘Even at the deepest point in the ocean you can still hear the noise from boats,' says biologist Hans Slabbekoorn. ‘And that's while sound is the most important means of communication for underwater life.' What is the effect of all that underwater noise on fish and other animals? Slabbekoorn is on board…

A flint tool covered with a tar-like substance has turned out to be a top scientific find. Research by a Dutch team of scientists showed the find to be a piece of birch tar that was extracted 50,000 years ago by Neanderthals using complex techniques. The tar was used as an adhesive to make it easier…

One of them turned out to be two thousand years old. And older giant barrel sponges appear to have a faster rate of cell division, unlike us. They produce antibiotics and much, much more. Lina Bayona Maldonado studied how the differences in such factors as age or oceanic depth affect the production…

A fragment of a human skull from the collection of the Dutch National Museum of Antiquities (RMO) and a decorated bison bone, both from the North Sea bed, are rare finds from the end of the last Ice Age.
