Synthetic cells, also known as artificial cells or protocells, have wide ranging applications from drug delivery vectors to cell models. In biotechnology they can function as micro- or nanoreactors with possible applications in biocatalysis and photocatalysis. Phospholipids are by far the most commonly…

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Hybrid Intelligence (HI) is the combination of human and machine intelligence, expanding human intellect instead of replacing it. HI takes human expertise and intentionality into account when making meaningful decisions and perform appropriate actions, together with ethical, legal and societal values.…

Does a moving hybrid zone leave a genomic footprint?

A Josephson junction is a device where a thin insulating barrier or a nanostructure is placed between two superconducting leads. Such a junction is essential to superconducting qubits that store quantum information due to its anharmonic spectrum.

‘It is OK for employees to work flexibly, as long as they spend 40 hours in the office’, said Elon Musk in June 2022. Are we back where we started now that the pandemic is over? What is needed to make flexibility prosper? Helen Pluut is researcher in Organizational Behaviour at Leiden University and…

Ben Wielstra studies hybrid zones, regions in which distinct populations of organisms meet, mate and produce genetically admixed offspring. In the journal Current Biology, he introduces hybrid zones in an accessible way.

Direct radiocarbon dating of human remains is crucial for the accurate interpretation of prehistory. Yet given the scarcity of prehistoric human remains, direct dating is often too destructive for important fossils. The reduction of sample size necessary for dating bone is therefore of great interest…
