Portugal's combined aviation and rail investment programme — the new Lisbon Airport at Alcochete (with its associated access infrastructure of a dual road-rail Tagus crossing and a high-speed-rail extension to Lisbon centre); the high-speed rail Lisbon-Porto line; the cross-border TEN-T links to Madrid, Salamanca, Vigo and Sines; and the conventional Linha do Norte modernisation — constitutes the largest peace-time public-infrastructure commitment in the country's modern history.

The four largest airports of Western Europe operate under markedly different constraint regimes. Madrid-Barajas retains substantial physical headroom, with a planned capacity expanding to approximately 100 million passengers per year by 2040. London is configured as a five-airport system in which growth depends on the long-debated and politically uncertain third runway at Heathrow.

Portugal's high-speed-rail programme — anchored on the 290-kilometre Lisbon-Porto line, with extensions to Madrid (Évora-Caia), Aveiro-Salamanca, Porto-Vigo and Sines, plus the Third Tagus Crossing and the conventional Linha do Norte modernisation — constitutes the largest single infrastructure commitment of the century in the national rail sector.

Artificial intelligence (AI) has moved from algorithmic novelty to a routine component of clinical workflow, biomedical discovery, and medical education. Drawing on a comparative review of six leading United States academic medical centers (UCSF, Stanford, MIT, Harvard/Mass General Brigham, NYU Langone, Duke) and four European peers (Oxford, ETH Zurich, Karolinska Institute, KU Leuven), this paper assesses (i) how far AI has progressed in supporting medical practice and teaching, (ii) why the United States currently leads Europe in clinical AI translation, and (iii) what role European universities play in closing the gap.

The health sector in Portugal spends €28 billion in 2024, of which about 39% is provided by the State and 54% by Private Entities. Health expenditure has been growing at a faster pace than GDP, with a strong acceleration after the Adjustment Programme, and is now about 2.5 percentage points above what would be expected for our GDP per capita.
