Between space exploits and environmental disappointments, AI breakthroughs and medical advances, our selection of the most notable moments of the year in science.
The brain in majesty
This year marked a turning point for neuroscience with major advances in brain mapping, opening dizzying perspectives for understanding the functioning of the human brain and the fight against neurodegenerative diseases such as Alzheimer's or Parkinson's. In May, Harvard University and Google's Connectomics team notably unveiled a digital reconstruction of a cubic millimeter of the human brain, mapping 150 million connections established between 57,000 neurons.
This neuronal hyperconnection is particularly intriguing. A few months later, in October, a study carried out by the FlyWire Consortium made headlines by proposing the first complete mapping of the brain of a fly, the Drosophila, a biological model widely used in neuroscience. Its “connectome” details the 50 million connections linking the 129,255 neurons of this small brain…
