A new study by the Singapore-MIT Alliance for Research and Technology’s (SMART) Mens, Manus & Machina (M3S) interdisciplinary research group, alongside collaborators from Massachusetts Institute of Technology (MIT) and National University of Singapore (NUS), has identified a strong statistical association between global air connectivity and patterns of where multinational corporations (MNCs) invest and set up subsidiaries. This is the most comprehensive global study merging 7.5 million firm records with 30 years of international flight data across more than 800 cities in 142 countries.

A new study investigates a mysterious Greek inscription in a bid to shed light on the longstanding question of whether the Great Mosque of Homs in Syria was constructed over the remains of the Temple of Elagabalus – the sanctuary dedicated to the Roman Emperor who served as the temple’s high priest prior to his accession in 218 AD.

An article by Mississippi State University researchers examines new evidence from ancient DNA that pushes the origins of diseases closely related to syphilis back more than 5,000 years and strongly supports an American rather than European origin for a close relative of the disease.

Think of the economy as a giant web where every person, company, and country is linked. When something big happens — a pandemic, the rise of artificial intelligence, or a climate-driven disaster — it doesn’t just hit one strand. The shock ripples across the entire web, creating effects in real time that are hard to predict.

That’s the central theme of The Economy as an Evolving Complex System IV (SFI Press, 2026), the newest volumes in a series launched at the Santa Fe Institute nearly four decades ago to rethink economics through the lens of complexity science. Rather than assuming markets always balance neatly, these books treat the economy as a living system that grows, changes, and reacts in ways that are hard to predict.

Cleaner fish interacted with a mirror in their tank in a way that suggests ‘contingency testing’ intelligence, a higher form of smarts typically found in mammals. This finding coupled with faster self-recognition than previously thought, expands our image of intelligence in these social fish.
