Yuma Kato

Graduated from Nagoya City University, Faculty of Pharmaceutical Sciences, Department of Biopharmaceutics, currently enrolled in the doctoral program at the University of Tokyo, Graduate School of Pharmaceutical Sciences, Pharmaceutical Science Major. His specialties are molecular biology and neuroscience. His research theme focuses on basic research for the treatment of Alzheimer’s disease.

My specialization is molecular biology and neuroscience, and I usually conduct research aimed at treating Alzheimer’s disease, which is one of the leading causes of dementia.

Molecular biology is a field that focuses on molecules within biology, primarily tracking actions at the single-cell level, often involving experiments like genetic manipulation. Although not my main area, I am also interested in how the brain perceives the world (cognition) and how it interacts with it (behavior) in neuroscience.

As a doctoral student, it feels somewhat presumptuous to represent my field, but I would like to share my personal thoughts on “Fashion and Technology” based on insights from biology in such a setting.

I want to clarify that this is solely an individual opinion and is not intended as a personal attack.

Biologically Attractive Faces

When I received this theme, one of the first experiments that came to mind was by Langlois and Roggman, titled "Attractive Faces Are Only Average."

In this experiment, they prepared photographs of young male and female faces, processed each image using a computer, and created composite images mixing faces of 2, 4, 8, 16, and 32 individuals. When 300 evaluators rated the attractiveness of the original individuals' faces versus the composite faces on a 5-point scale, the results showed that the composites featuring a higher number of faces were rated more attractive than those with fewer.
