The three Nobel Prize laureates in physics 2023 are being recognised for their experiments, which have given humanity new tools for exploring the world of electrons inside atoms and molecules. They have demonstrated a way to create extremely short pulses of light that can be used to measure the rapid processes in which electrons move or change energy.

Moungi G. Bawendi, Louis E. Brus and Aleksey Yekimov are awarded the Nobel Prize in Chemistry 2023 for the discovery and development of quantum dots. These tiny particles have unique properties and now spread their light from television screens and LED lamps. They catalyse chemical reactions and their clear light can illuminate tumour tissue for a surgeon.

The discoveries by the two Nobel Prize laureates were critical for developing effective mRNA vaccines against COVID-19 during the pandemic that began in early 2020. Through their groundbreaking findings, which have fundamentally changed our understanding of how mRNA interacts with our immune system, the laureates contributed to the unprecedented rate of vaccine development during one of the greatest threats to human health in modern times.

The Nobel Prize in Literature 2023 is awarded to the Norwegian author Jon Fosse, “for his innovative plays and prose which give voice to the unsayable.”

His immense oeuvre written in Norwegian Nynorsk and spanning a variety of genres consists of a wealth of plays, novels, poetry collections, essays, children’s books and translations. While he is today one of the most widely performed playwrights in the world, he has also become increasingly recognised for his prose.

The Norwegian Nobel Committee has decided to award the Nobel Peace Prize 2023 to Narges Mohammadi for her fight against the oppression of women in Iran and her fight to promote human rights and freedom for all.

This year’s peace prize also recognises the hundreds of thousands of people who, in the preceding year, have demonstrated against Iran’s theocratic regime’s policies of discrimination and oppression targeting women. The motto adopted by the demonstrators – “Woman – Life – Freedom” – suitably expresses the dedication and work of Narges Mohammadi.

Over the past century, the proportion of women in paid work has tripled in many high-income countries. This is one of the biggest societal and economic changes in the labour market in modern times, but significant gender differences remain. It was first in the 1980s that a researcher adopted a comprehensive approach to explaining the source of these differences. Claudia Goldin’s research has given us new and often surprising insights into women’s historical and contemporary roles in the labour market.
