Key takeaways
The 2023 Nobel Prize in Physics was awarded to Pierre Agostini, Ferenc Krausz and Anne L’Huillier for their work on attosecond laser pulses.
These lasers pulses make it possible to observe the dynamics of electrons in matter and open the door to a wide range of studies.
The generation of attosecond pulses is mainly based on the method of colliding electrons with their atoms, developed by Anne L’Huillier.
This ability to take a snapshot of the infinitely small is useful in many fields, such as biology, to gain a better understanding of the damage caused to DNA by certain types of radiation.
In the future, scientists hope to develop even shorter pulses to observe protons and neutrons in atomic nuclei.

Key takeaways
The American economist Claudia Goldin was awarded the Nobel Prize in Economics in 2023 for her work on the place of women in the labour market with her analyses of wage inequality.
She has shown that women’s participation in the economy has followed a U-shaped trajectory, influenced by major societal changes such as the contraceptive pill.
Her working method is particularly innovative, drawing on historical data, analysing the long term and formulating multiple hypotheses.
Claudia Goldin describes a “silent revolution” in the early 1970s, launched in particular by contraception, which enabled American women to plan and build their professional careers.
Despite this progress, the economist notes that pay inequalities persist, notably because of “greedy jobs” and flexible working.

Key takeaways
CRISPRs are DNA sequences found in many prokaryotes, useful for defense against viruses, which have been adapted to develop a gene-editing tool.
CRISPR-Cas enables genomes to be modified rapidly and precisely, by cutting and inserting new DNA sequences.
Its applications are wide-ranging: gene therapy, healthcare, agriculture, bioproduction, etc.
CRIPSR-Cas raises many ethical questions, and its potential uses and implications give rise to widely differing opinions, notably in the European Parliament.
