The Medal Depends as Much on the Laboratory as on the Athlete
Ninety-four percent. That's the rate of agreement between neural networks and international experts when evaluating an athlete's technique. This figure, drawn from a systematic review of 73 studies published in 2025 in Bioengineering (MDPI), doesn't suggest that AI replaces the eye of coaches. It
AI Agents Enter the Enterprise, Work Organization Remains to Be Written
In 2025, Fortune 500 companies deployed an average of 35 autonomous artificial intelligence agents in their operations, compared to fewer than five two years earlier. This is not a metaphor about the speed of technological change. It is a concrete organizational fact, with consequences for who does
The Draghi Report: Diagnosis Adopted and Reforms Forgotten
Approximately two decades of relative competitive decline against the United States and China, with an acceleration of this divergence since the 2008 financial crisis, documented in 400 pages, summarized in 170 official recommendations, quantified at 800 billion euros of additional annual investment
Human Neurons to Pull AI Out of Its Energy Crisis
A medium-sized data center consumes between 5 and 20 MW, which represents the power supply of approximately 3,500 to 14,000 households — it is only for a large data center (50-70 MW) that the comparison with a city of 50,000 inhabitants becomes relevant. A human brain organoid, a few million neurons
Freight Sails Save the Equivalent of 170 Million Cars
Maritime freight transports approximately 90% of global trade by volume (and 80% by value). It produces roughly 3% of global CO2 emissions. And it still has no viable replacement fuel at scale before 2035, at best. Meanwhile, a technology thousands of years old has just received its first serious sc
The Living Planet Index: Does It Rest on a Statistical Bias?
The Living Planet Index, the reference figure of the COPs, is built on a structural statistical flaw The figure has entered the collective unconscious of climate negotiators: minus 73% of wild vertebrate populations between 1970 and 2020. Minus 85% for freshwater species. These data, produced by the
Free Public Transport Is Spreading Without Knowing If It Actually Clears the Roads
Ridership on Dunkerque buses jumped 85% after switching to complete free fares in 2018. This figure circulates in every debate on the subject. What is cited less often: according to the VIGS study, 48% of new users report having abandoned their cars — making it the mode most cited as forsaken. But i
Europe Faces the Chinese Solar Panel Dilemma
A Chinese solar module costs 0.08 euros per watt today. Eighteen months ago, it cost roughly double — Chinese module prices were then around 0.20 to 0.25 dollars per watt, or approximately 0.18 to 0.23 euros. This 50% price drop should be excellent news for the energy transition. It is becoming one
Twenty-First Century Health Gains Resist, but Their Momentum Erodes
Fifty-four million child deaths averted among children under five since 2000: this figure, whose order of magnitude is documented by major UN agencies, is the most spectacular result of a quarter century of massive investments in global health. It deserves to be read for what it is: one of the most
Africa Demands to Keep Its Doctors
Every year, hundreds of doctors and nurses trained in sub-Saharan Africa leave the continent to join British, French, or Canadian health systems. Kenya trains a doctor in 6 years (5 years of training followed by a year of internship), at a total estimated cost of approximately 66,000 USD in unsubsid
The WIPO Report: A Map of Global Technological Development
A patented invention in India will be reused three times faster by an American researcher than by an Indian researcher. This single figure, drawn from the 2026 WIPO report on global intellectual property, summarizes a reality that enthusiasm for the "democratization" of knowledge tends to mask: tech
China Surpasses the United States in R&D While They Dismantle Their Advantage
China now devotes more to research than the United States. In purchasing power parity, both countries have each crossed the 1 trillion dollar threshold in R&D spending, but it is Beijing that has taken the lead according to the latest OECD data published in March 2026. That same year, the Nature Ind
Social Mobility Also Passes Through Freedom to Entrepreneurship
In OECD countries, the correlation between a poor child's capacity to become a wealthy adult and the entrepreneurial dynamism of their country is comparable to that measured with educational spending. This is the central finding of a study published in 2026 by Causa, Nguyen and Tanaka, which covers
Energy Storage Erases the Intermittency Argument, China Holds the Key
In a single year, the cost of battery storage fell by 40%. According to the BNEF Battery Storage System Cost Survey, the cost of stationary battery energy storage systems (BESS) stood at $165 per kWh in 2024, while the price of lithium-ion packs for all uses reached $115 per kWh. The International E
Banning Phones at School Doesn't Save Grades but Reveals Another Issue
Approximately 4,600 American schools studied with data from 2014 to 2026, zero measurable improvement in academic results or attention. The largest study ever conducted on phone bans in classrooms has just delivered its findings: confiscating mobile phones does not improve student performance, but t
Internal Climate Displacement Overwhelms Border Migrations
83.4 million people were living in internal displacement at the end of 2024, of which 9.8 million due to disasters. Climate disasters explain the majority of new internal displacements. This massive reality contrasts with European obsession with cross-border migrations: the bulk of forced mobility o
Universal Basic Income: Neither Promise Nor Catastrophe, the Debate Shifts
122 pilots later, data finally breaks the two dominant narratives about universal basic income. Among the four experiments with more than 500 participants, the average effect on employment is -3.2 percentage points — neither the collapse predicted by conservatives, nor the neutrality hoped for by pr
Aviation Has Bet on a Fuel That Doesn't Exist Yet
2.4 million tonnes. That is the global production of sustainable fuels for aviation expected in 2026, according to IATA. In other words, 0.8% of current worldwide kerosene consumption. To achieve net zero by 2050, this production will need to be multiplied by 200, reaching 500 million tonnes annuall
India Ages Before Growing Rich: The Demographic Dividend Trap
Two-thirds of Indians are under 35 years old. But only one woman in three works. This arithmetic contradiction summarizes the most complex demographic challenge of the century: how to transform 900 million young people into an engine of growth when a significant portion of this human capital remains
The Death of Local Journalism Costs Lives in Crime, Polarization, and Mental Health
One in five Americans now lives in a local news desert. This statistic, which might seem abstract, masks a very real human and social cost. When a local newspaper closes its doors, property crime rates increase, political polarization worsens, and days of poor mental health multiply. A study in the
South-South Trade Escapes the Radar of the IMF and OECD
In nine countries in Latin America and the Caribbean, 99% of South-South cooperation exchanges take place without passing through traditional financial circuits. Cuban engineers building hospitals in Venezuela, Indian doctors training their African counterparts, Brazilian agricultural equipment exch
Magnetic Microrobots Repair Severed Spinal Cords in Less Than a Month
15 million people worldwide live with spinal cord injuries, condemned to paralysis by the central nervous system's inability to regenerate. The ETH Zurich team has just shattered this inevitability with biohybrid microrobots that restored mobility in paralyzed mice in 28 days. These microscopic mach
Batteries Push Solar Into the Night
108 gigawatts of storage capacity installed globally in 2025, eleven times more than in 2021. These figures from the International Energy Agency document a major shift: 90% of batteries now serve temporal shifting — storing solar electricity during the day and returning it at night. The main use of
The AI Race, an Electric Battle That Gas Is Winning
Data centers worldwide will consume 945 terawatt-hours of electricity in 2030, equivalent to Japan's annual consumption. In the United States, they will capture half of the growth in electricity demand and consume more than aluminum, steel, cement, and chemicals combined. This energy explosion from
