Data Science
The majority of scientists, from archaeologists through to zoologists, collect huge volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics, we can develop algorithms for analysing and identifying patterns…

Scleral pigmentation leads to conspicuous, not cryptic, eye morphology in chimpanzees
Researchers of the National University of Singapore and Leiden University have discovered that chimpanzees and bonobos share the contrasting colour pattern seen in human eyes, which makes it easy for them to detect the direction of someone’s gaze from a distance.

Coin streams within the Roman West (AD 83-138)
Ancient historians have long been aware that patterns of coin circulation can shed light on levels of economic integration in the Roman Empire. More than forty years ago, Hopkins argued that large amounts of tax money were spent in the frontier provinces and that the non-military provinces recouped…

Remote sensing-based assessment of functional diversity for polar ecosystems
1: What is the relative importance of alfa and beta biodiversity in polar ecosystems, and how does intraspecific variation influence this? 2: How can we use remote sensing to determine functional biodiversity (within communities) in polar ecosystems? 3: Temporal and spatial scales of functional biodiversity:…

Visual analytics for spatially-resolved omics data at single cell resolution: Methods and Applications
The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

Mood variability during adolescent development and its relation to sleep and brain development
During adolescence, mood disorder onset peaks. Mood variability is associated with negative mental health outcomes, so understanding biological factors that might be associated with mood variability, such as sleep and structural brain development, could elucidate the mechanisms underlying mood and anxiety…

The archaeology of face masks: ‘Face masks layers will be a huge help for future archaeologists’
From one year to the next, face masks have started to appear in the environment. As the masks are discarded, they end up in the top soil, in sediment layers, and in refuse heaps. In a couple of generations archaeologists will study the layer that has already been labeled the Face Mask Horizon. Current…
