Wie is er aan de beurt? De rol van spraakmelodie bij beurtwisselingen in het Nederlands
Als mensen met elkaar praten wisselen sprekers elkaar soepel af, met gemiddeld zeer korte tussenliggende pauzes. Gesprekspartners moeten daarom steeds vooruit plannen wat ze willen zeggen en wanneer ze de beurt kunnen overnemen. Spraakmelodie speelt hier hoogstwaarschijnlijk een rol bij, maar onduidelijk…

Neanderthalers konden zelf vuur maken – net als onze moderne voorouders
Neanderthalers konden op grote schaal vuur maken met behulp van pyriet en hun vuistbijlen. Ze konden dus zelf beslissen wanneer zij vuur wilden en waren niet afhankelijk van natuurbranden, zoals eerder gedacht werd. Archeoloog Andrew Sorensen ontdekte het eerste materiële bewijs hiervoor.

Speciale telescoop meet neutrino met hoogste energie ooit
Zelfs met de allermodernste technieken is het bijna niet te zien: een kosmische neutrino. Toch is het wetenschappers gelukt dit deeltje in beeld te brengen met een telescoop op 3450 meter diepte in zee. En dat kan helpen om ons universum beter te begrijpen. Leidse deeltjesfysici werkten mee aan dit…
