eDNA a useful tool for early detection of invasive green crab

European green crabs feast on shellfish, destroy marsh habitats by burrowing in the mud and obliterate valuable seagrass beds. The invasive species also reproduces quickly, making it a nightmare for wildlife managers seeking ...

Hidden order in windswept sand

An interdisciplinary team including researchers from Leipzig University has analyzed an extensive collection of sand samples from so-called megaripple fields around the world and gained new insights into the composition of ...

To better understand speech, focus on who is talking

Seeing a person's face as we are talking to them greatly improves our ability to understand their speech. While previous studies indicate that the timing of words-to-mouth movements across the senses is critical to this audio-visual ...
