00:49 Separating heavy water with molecular cages

Heavy water is molecule similar to H2O however with deuterium isotopes within the place of hydrogen atoms. Heavy water is helpful in nuclear reactions, drug design and dietary research, however it’s troublesome to separate from regular water as a result of they’ve such related properties. Now, a crew have developed a brand new separation technique utilizing tiny molecular cages, which they hope opens up extra vitality environment friendly methods to supply heavy water.

09:25 Monitoring bridge well being utilizing crowd information

Bridges are essential items of infrastructure however their structural well being is difficult to watch, requiring both subtle sensors or intense surveying by human engineers. Now although, researchers have utilized massive quantities of smartphone accelerometer information to verify the well being of the Golden Gate Bridge. They hope this new approach can be utilized to successfully and cheaply monitor bridges world wide.

This week the twenty seventh UN Local weather Change Convention started, with world leaders, scientists and activists coming collectively to proceed negotiations geared toward reining in international warming. Jeff Tollefson, senior reporter at Nature, joined us to speak about what’s been occurring and what to anticipate, because the convention continues.
