Floodgates Might Not Save Venice

The construction of mobile floodgates aims to safeguard the 1,300-year-old island city of Venice. It's an ambitious engineering project, but some scientists say it may not be sufficient to protect Venice from rising sea levels due to climate change.

Using waste to recover waste uranium

 Using bacteria and inositol phosphate, a chemical analogue of a cheap waste material from plants, researchers at Birmingham University have recovered uranium from the polluted waters from uranium mines. The same technology can also be used to clean up nuclear waste. Professor Lynne Macaskie, , presented the group's work to the Society for General Microbiology's meeting at Heriot-Watt University, Edinburgh.
