Hello dear Good News community,
Today it’s all about innovations that benefit both people and wildlife: cities learning from the wind to stay cooler, fiber-optic cables helping protect orcas, 3D-printed antennas that could improve the communication of the future, and CO₂ filters for buildings. Get ready to explore these exciting developments!
Enjoy reading, Selina
NEWS OF THE DAY
(S'ouvre dans une nouvelle fenêtre)WHO confirms: Fiji is free of trachoma
The WHO has confirmed that Fiji has eliminated trachoma – the world’s leading infectious cause of blindness. The disease is no longer considered a public health threat in the country. This marks the first neglected tropical disease (NTD) to be eradicated in Fiji, making it the 26th country worldwide to defeat trachoma. Source: EPINEWS

Researchers develop CO₂ filter for homes and offices
Scientists have developed a new CO₂-capturing air filter that can be integrated into existing ventilation systems in homes and offices. The filter is made of nanofibers with a special polymer coating that binds CO₂ even at low concentrations. Tests show the filter achieves an impressive net CO₂ removal efficiency of 92 percent.

3D-printed antenna arrays could revolutionize wireless systems
Researchers at Washington State University have combined chip-sized processors with 3D-printed antenna arrays. The arrays, made from copper nanoparticle ink, are flexible and versatile. The goal is to create portable wireless systems for enhanced communication, with potential applications ranging from automobiles to aerospace. Source: TECH XPLORE

Fiber-optic cables as underwater microphones: Protecting orcas in real time
In the Salish Sea, underwater fiber-optic cables are being turned into giant whale microphones. Researchers use them to capture clicks, calls, and whistles of passing orcas. This helps better understand the impacts of shipping traffic, food scarcity, and climate change. If the experiment succeeds, existing fiber networks worldwide could support conservation efforts.

Singing classes help ease postpartum depression
Specially designed singing classes have been shown to help mothers with postpartum depression. Nearly 200 women participated in a three-year study comparing the courses with standard support. After just ten weeks, all participants reported symptom relief. In the singing group, the effects lasted for six months after the course ended. Source: BBC

How cities learn from the wind: Stuttgart as a model for urban cooling
Climate change is making many cities hotter and harder to live in. Stuttgart addresses the problem with wind corridors that channel fresh air from surrounding hills into the city, providing cooling. The method is internationally recognized as a model. Singapore is also planning buildings to allow natural breezes to flow through urban areas. Source: BBC
