On World Neglected Tropical Diseases Day, we discuss the need for an integrated approach to overcome the “last mile” barriers to achieving their eradication and elimination

Neglected tropical diseases: the need for an integrated approach to achieve the 2030 roadmap - Nature Communications
Neglected tropical diseases are ancient maladies that continue to disproportionately affect more than one billion of the world’s poorest people. In 2021, as part of its strategy to achieve the Sustainable Development Goals, the World Health Organization renewed its commitment to end their neglect by 2030. On World Neglected Tropical Diseases Day 2026, we discuss the need for an integrated approach to overcome the “last mile” barriers to achieving their eradication and elimination.

‪This was a fun story to write.

Last year, environmental police in Brazil stumbled upon thousands of climbing bumblebee catfish. Scientists know almost nothing about this species, which only became known to science in 2017. 🧪🌿🌎
Researchers have filmed thousands of climbing catfish scaling waterfalls, providing a rare insight into the daring migration of an enigmatic fish.
