Internet shutdowns in Latin America

Internet shutdowns in Latin America. Also, the world’s first 3D-printed steel bridge unveiled in Amsterdam, and using machine learning to remotely monitor ecosystem sounds

As protests continue in Cuba, so do its internet shutdowns. Anti-government protesters are demonstrating against food shortages, power cuts and coronavirus restrictions. In response Cuban authorities have been shutting down internet connections in an attempt to stop protests. Meanwhile Venezuela is becoming known for its frequent online restrictions. David Aragort from Latin American tech rights NGO RedesAyuda updates us on what has been going on.
The world’s first 3D printed smart bridge
The world's first 3D-printed steel bridge has been unveiled in Amsterdam. Pedestrians can now use it to cross over the Oudezijds Achterburgwal canal. Sensors will continuously monitor how the bridge is used and its ongoing safety. This data will influence how other 3D-printed structures could be built in the future. Professor Leroy Gardner and Dr. Craig Buchanan from Imperial College’s Department of Civil and Environmental Engineering tell us more.

Ecosystem soundscape monitoring with AI
One way to monitor the health of an ecosystem is through sound. Anthea Lacchia reports on how scientists are using machine learning to monitor these ecosystem sounds. From Okinawa to Borneo, they can listen to the sounds of the forest without having to be physically present.

The programme is presented by Gareth Mitchell with expert commentary from Bill Thompson
