Conspiracy thinking and social media use are associated with ability to detect deepfakes
Deepfakes are videos that have been manipulated to replace one person’s likeness with that of another. They can be difficult to distinguish from authentic videos. In our study, we found that people who score high on conspiracy thinking and people who use social media more are better at distinguishing…

The use of Deep Learning in the automated detection of archaeological objects in remotely sensed data
Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…

From detection to sentencing: a homicide case flow analysis of the Dutch criminal justice system
Homicide engenders broad moral concerns in society, and its aftermath can be understood as a barometer for criminal justice policy. Of all homicides committed, however, only some lead to arrest, to prosecution and ultimately to conviction in court.

Novel detection method for iron in Alzheimer’s brain
For many years, scientists have observed a correlation between Alzheimer’s disease and a surplus of iron in the brain. However, a causal link between the two has not been proven yet. We lack knowledge concerning the specific form of iron that is involved in the development of neurodegenerative diseases.…
