How do you capture the image of a 140-foot-tall tree in the middle of a dense rainforest? If you’re National Geographic Explorer Nirupa Rao, you pull out your paints. Celebrate Earth Day by learning how Rao pulls from the centuries-old practice of botanical illustration to catalog and celebrate native plant life of the southern Indian rainforest—even when king cobras and leeches get in the way—and introduce new audiences to this hidden kingdom.

About Overheard at National Geographic:
Documenting democracy, Untwisting the world’s largest tornado. Searching for wrecks of lost slave ships. Dinosaur hunting in Morocco. Accidentally inventing a new color. Come dive into one of the curiously delightful conversations overheard at National Geographic’s headquarters, as we follow explorers, photographers, and scientists to the edges of our big, weird, beautiful world. Hosted by Peter Gwin and Amy Briggs.

About National Geographic:

Challenging the resource-intensive "bigger is better" trend of Large Language Models (LLMs), this webinar introduced the Expressive Neural Network (ENN). This novel architecture rethinks activation functions using classical signal processing (Discrete Cosine Transform), resulting in enhanced flexibility, faster convergence, and significantly smaller, more energy-efficient AI models.

ENNs demonstrate how traditional signal processing can inspire next-generation AI, enabling efficient edge computing in resource-constrained environments. This approach prioritizes expressiveness over sheer size for future neural networks. The webinar featured speaker Ana Pérez-Neira, moderated by Ian F. Akyildiz and Alessia Magliarditi. It was organized by the ITU Journal on Future and Evolving Technologies (ITU-J FET).

A technical webinar on new World Telecommunication/ICT (WTI) Indicators provided insights into their relevance, implementation, and data submission to the ITU. Participants learned about common challenges and practical solutions for enhancing data quality and comparability.

This activity was organized under the ITU's EU-funded project, "Promoting and Measuring Universal and Meaningful Connectivity." Implemented by the ICT Data and Analytics Division (IDA), the project aims to strengthen statistical capacities in developing countries through various webinars and workshops.

Machine learning, a key AI technique, enables systems to learn from data without explicit programming. ITU standards are crucial in applying machine learning to develop smarter, more efficient

This technical webinar targeted professionals compiling ICT household statistics, aiming to improve data quality on individuals' ICT access and use in ITU member states. Participants learned best practices for gathering data through household surveys.

Organized under the ITU project "Promoting and Measuring Universal and Meaningful Connectivity," and funded by the European Union, this activity strengthens the statistical capacities of national statistical offices and regulatory authorities, particularly in developing countries. The ICT Data and Analytics Division (IDA) implements these webinars and workshops.

This technical webinar, designed for national statistics offices and government agencies conducting ICT household surveys, covered ITU's data collection and validation processes. Participants learned about new recommendations for ICT skills data and how to reduce response burden by submitting simple CSV files.

Organized under the EU-funded ITU project "Promoting and Measuring Universal and Meaningful Connectivity," this activity strengthens the statistical capacities of NSOs and regulatory authorities, particularly in developing countries, through webinars and workshops by the ICT Data and Analytics Division (IDA).
