Archaeological research often focuses on broad geographical areas, time periods, or big data. In wide generalisations, nuances and details are lost. Ulla Moilanen studied Medieval (c. 900 – 1400 AD) inhumation graves in Finland and found out that the period was more diverse than previously thought.
We know that in the centres of the majority of galaxies lies a supermassive black hole. New observations of certain galaxies reveal that these black holes may be consuming stars at a higher rate than previously known. The energy produced by the destruction of the star can be revealed in the infrared, as heat from cosmic dust warmed by the explosion.
Stellar-mass black holes that are part of binary systems sometimes show variable polarization of optical emission. The degree, angle and variability pattern of polarization is characteristic of the physical processes occurring in the vicinity of a black hole. By studying black holes astronomers learn how matter and energy behave under extreme conditions.
Master of Social Sciences, Master of Arts Tiia Sudenkaarne introduces queer bioethics into Finnish academia. Her dissertation analyses how LGBTQI+ questions often considered marginal are philosophically robust and socio-politically important.
Contracts are fundamental for today’s networked business practices. Various professionals plan, design, and implement contracts, yet many of them find contracts difficult or even impossible to understand. In addition, contracts are mostly designed to protect parties in case something goes wrong––not to support collaboration.
Doctoral Candidate Tapani Hopkins collected over 100,000 parasitoid wasps from the tropical forest of Uganda during his doctoral dissertation. Current results suggest that there is a diverse parasitoid wasp fauna still awaiting discovery in tropical Africa. His dissertation defence on rhyssine wasp species, their ecology, and how their diversity compares to Amazonia will be held online. Questions are welcome after the event.
