Registration is live for the seventh edition of the XTF Global Innovation Challenge — the largest open student science competition in our history. We expanded the prize pool, added two new tracks (Quantum & Computing, Cybersecurity & Privacy), and raised travel funding so every finalist team gets to Geneva regardless of nationality.
The "BioMesh" team — three high-schoolers from Nairobi, São Paulo and Kuala Lumpur — describe what came after the trophy: paper accepted to Lab on a Chip, three university offers between them, and a Continuation Grant to harden their low-cost paper microfluidic assay for arsenic in groundwater.
Two years after launch, the CC BY-SA module library now covers all eight innovation tracks in six languages. Highest growth is in Portuguese-language modules (3.4× year-over-year), led by educator clubs in Brazil, Portugal, Mozambique and Cape Verde.
This year's AI track panel asks competitors to focus on three questions: small-model evaluation on under-served languages, mechanistic interpretability of agents on tasks with verifiable ground truth, and applied ML for the sciences. Scale of compute is explicitly not a scoring factor.
Dr. Aisha Rahman, XTF Senior Judge in the BioTech track and Group Leader at EMBL-EBI, on what it's actually like to review student-led science — and why she now spends a fifth of her year doing it.
The renewed agreement adds two languages (Swahili and Bahasa Indonesia), funds 14 new modules in cybersecurity and civic tech, and underwrites translation of the existing library to AAA accessibility standards.
We're recruiting the 2026 mentor cohort. Mentors are matched 1:1 with shortlisted teams from October through the Grand Finals — typically 8–15 hours of consultation over three months. PhD students and postdocs make up 64% of the network.
The 2025 volume — 47 student-led papers across the eight tracks — is fully indexed and DOI'd. All papers are CC BY 4.0. The most-downloaded paper this month is a Junior Division entry on backyard radio telescopy from a 14-year-old in Bucharest.
The 2025 Grand Champion went to "BioMesh" (Junior Division, BioTech & Health) for an ultra-low-cost paper microfluidic arsenic assay. Track winners spanned six continents; full results, judges' notes and finalist videos are now online.
Two years into blind first-round review, we have data. Of teams advancing from blind round to shortlist, the share from low- and middle-income countries rose from 19% (2022, pre-blind) to 34% (2024, blind). We unpack the methodology, the criticisms we've received, and what we're still trying to fix.
Following two years of judges' commentary, the Climate track now publishes an explicit LCA scoring sub-rubric. Projects that use public-domain datasets (Copernicus, NASA, NOAA, ERA5) and document their carbon assumptions transparently get the rubric's "5."
1,247 active mentors, 47 countries, 35% are XTF alumni. Median commitment is 11 hours per cycle. Lowest no-show rate (1.4%) of any mentor program we benchmarked against. We publish the full demographics and methodology.
The three organisations align on a shared standard for AI tool disclosure in student research: use is permitted with disclosure, defendability is required at judging, and undisclosed reliance on third-party models in the AI track is a disqualifying offence. Full text and FAQ below.
312 teams from 41 countries advance to the 2025 semi-finals. The Junior Division saw a record share of shortlisted teams (28%) — the highest since the competition's inception. Country list, methodology and per-track demographic notes inside.
A long-form profile of Ifeoma Eze, Senior Division finalist (Space & Aerospace, 2024). She walks us through hardware sourcing in a city where the nearest aerospace supplier is 3,400 km away, why she abandoned her first three antenna designs, and why she's mentoring three teams in the 2026 cycle.
The 2025 cycle closed with a 24% year-over-year increase in submissions. Largest single-country delegations: India (612), Brazil (388), the United States (341), Nigeria (302) and Indonesia (281). Geographic distribution, division splits and track breakdown released.
The Alliance — a coalition of 31 universities across 12 jurisdictions — will host four regional pre-finals workshops in 2026 (Singapore, Tokyo, Bengaluru and Jakarta). Workshops are open to any registered XTF team in the region; participation is not required to advance.
