(Press-News.org) ECMWF is throwing down the gauntlet on a brand-new set of data challenges waiting to be solved as part of its Code for Earth programme.
Improving rapid decision-making during wildfires, exploring flood forecast data from 10,000 stations globally and detecting implausible behaviour in machine learning are just some of the aims of this year’s challenges.
Every year the European Centre for Medium-Range Weather Forecasts (ECMWF) invites individuals or groups to deliver solutions to given problem statements, so called challenges, that may improve how we use, visualise and interpret Earth science data. The ultimate aim is to help address today’s most pressing environmental and climate challenges.
“We’re excited to announce this year’s round which as usual contains a whole variety of opportunities”, said Athina Trakas, ECMWF Innovation Actions and Partnerships Coordinator and lead of the Code for Earth Coordination Team.
“Code for Earth is all about innovation, collaboration and open-source coding and each year we look forward to meeting the participants and discovering the innovative solutions they bring. As well as the chance to explore new ideas and support ECMWF’s development needs, a big part of Code for Earth is the opportunity to network with like-minded people and build new partnerships”.
The challenges are organised by ECMWF with support from the Copernicus Climate Change Service (C3S), the Copernicus Atmosphere Monitoring Service (CAMS), Destination Earth and Strengthening Early Warning in Africa (SEWA). They come under four streams: data visualisation, machine learning and software development, and for the first time this year, an additional stream, focusing specifically on joint challenges with African partner organisations.
Teams will co-develop open-source tools and services that support stronger early warning systems, build regional innovation capacity, and help address key challenges in weather and climate, and, in the fourth stream, climate change resilience and digital transition in Africa, defined by local or regional challenge partners.
“Having this additional stream in Code for Earth will also support African young talent through the opportunity to work on real world challenges in the region, bring new innovation to ECMWF, and build on engagement between European meteorological community, and the African WMO Regional Climate Centres,” says Stijn Vermoote, Head of Partnerships and Engagement Section at ECMWF.
Eligibility details for all streams can be found in the FAQ page on Code for Earth’s website.
After the Call for Participation, selected applicants work individually or in teams, guided by experienced and expert mentors from ECMWF and partner organisations, to solve real-world challenges with applied data science, computing and open source software coding. All individuals or teams that complete their project successfully will be recognised for their achievements.
Code for Earth has run since 2018. Last year, successes included making meteorological charts for visually impaired scientists, an interactive platform visualising the impact of extreme weather events on energy systems and an application enabling you to zoom into your hometown and see how a local sandstorm or forest fire affects air quality.
The deadline for this year’s applications is strictly 23:59 Central European Time (GMT+1) on 9 April 2026.
For details on how to apply, and terms and conditions, see the Code for Earth website.

Have abortion-related laws affected broader access to maternal health care?
2026-02-25
A study in Health Economics uncovers a major unintended consequence of abortion‐related regulations: a measurable decline in the availability of obstetricians and gynecologists.
Since 2010, increasing numbers of states across the US have enacted Targeted Regulation of Abortion Providers (TRAP) laws that require abortion clinics to adhere to stringent and often medically unnecessary standards. By analyzing 2010–2021 data, investigators found that TRAP laws significantly reduced the supply of obstetricians and gynecologists—particularly older and newly trained doctors—without corresponding increases in midwives, nurse practitioners, and physician ...
Do muscles remember being weak?
2026-02-25
Muscle loss, or atrophy, due to inactivity is common after illness, injury, hospitalization or falls, and becomes increasingly frequent with aging. New research published in Advanced Science shows that skeletal muscle retains a “molecular memory” of repeated disuse—and that this memory differs markedly between young and old muscles.
For the study, researchers combined repeated lower‑limb immobilization in young adults with an aged‑rat model to enable age comparisons. In young adults, repeated disuse resulted in a similar amount of muscle atrophy during both periods; however, the molecular response showed a protective memory. Oxidative and mitochondrial ...
Do certain circulating small non-coding RNAs affect longevity?
2026-02-25
Research in Aging Cell indicates that blood levels of particular small non-coding RNAs, which regulate gene expression, may influence how long a person lives.
Investigators evaluated 828 small non-coding RNAs in blood samples from 1,271 community-dwelling older adults 71 years of age and older who were participating in an ongoing study. They then used machine learning to develop a model that could predict survival at 2, 5, and 10 years based on baseline small non-coding RNAs, age, and clinical variables (demographics, lifestyle, mood, physical function, standard clinical laboratory ...
How well are international guidelines followed for certain medications for high-risk pregnancies?
2026-02-25
Prenatal magnesium sulfate and steroids can reduce the risks of cerebral palsy and respiratory complications in preterm infants. A review in the International Journal of Gynecology & Obstetrics found that despite being recommended internationally for pregnant women at risk of preterm delivery, these medications are used variably between and within countries.
When they analyzed 2012–2024 information on 45,619 babies born at 24–32 weeks' gestation at 1,111 hospitals in an international network, along with information from the UK National Neonatal Research Database and a literature ...
New blood test signals who is most likely to live longer, study finds
2026-02-25
DURHAM, N.C. – As people age, it becomes harder to know who is on track for healthy years ahead and who may be at higher risk for serious decline. A new study suggests that part of the answer may already be circulating in the bloodstream.
Research led by Duke Health, in collaboration with the University of Minnesota, has found that small RNA molecules known as piRNAs can accurately predict whether older adults are likely to survive at least two more years.
The findings, published February 25 in Aging Cell, suggest that a simple blood test could ...
Global gaps in use of two life-saving antenatal treatments for premature babies, reveals worldwide analysis
2026-02-25
A new global analysis of two antenatal treatments that reduce the risk of cerebral palsy and respiratory complications in premature babies reveals significant international variation in implementation. The University of Bristol-led study, published in the International Journal of Obstetrics & Gynaecology today [25 February], examined neonatal data from over 300,000 premature births across ten countries.
When a baby is born before 30 weeks of gestation, they have a higher risk of death or serious health challenges, including stroke, respiratory problems, and disabilities like cerebral palsy. Magnesium sulphate is a cost-effective treatment that, when given ...
Bug beats: caterpillars use complex rhythms to communicate with ants
2026-02-25
Research from the University of Warwick has revealed that butterfly caterpillars use sophisticated rhythmic signals to communicate with ants, helping them gain protection, food, and access to ant nests.
Some butterfly species rely on ants for survival during their early life stages as caterpillars. The ants treat the baby caterpillars like colony members, carrying them into nests, protecting them from predators, and even feeding them. In exchange, caterpillars provide sugary secretions to ants or behave in ways that mimic ant behaviour to integrate with the colony.
While ...
High-risk patients account for 80% of post-surgery deaths
2026-02-25
A major new study, led by Queen Mary University of London and funded by the National Institute for Health and Care Research (NIHR) has been published in The Lancet Public Health. It found that out of the five million surgical procedures performed each year by the NHS, around 300,000 are carried out on individuals considered high-risk, and within 90 days of surgery, these high-risk patients account for:
four out of five deaths
over half of all hospital bed days
nearly one-third of emergency readmissions
While surgery is safer than ...
Celebrity dolphin of Venice doesn’t need special protection – except from humans
2026-02-25
Bottlenose dolphins usually live in small to medium-sized groups in coastal and open-sea waters, but every once in a while, a dolphin might leave its pod behind, flock to coastal areas and approach human settlements. While this is a relatively rare occurrence, cases of dolphins entering coastal or urban areas are well-documented.
When a bottlenose dolphin nicknamed Mimmo was first spotted in the lagoon of Venice last summer, local researchers jumped into action. The team has now published a Frontiers in Ethology article in which they describe their monitoring activities and the dolphin’s movements over several months, while also assessing management scenarios.
“We ...
