The political message from the COP meeting was a fudge over coal, but what does the science say? Surprisingly India seems to be on track to switch away from coal to renewables. We explore the apparent contradiction with Lauri Myllyvirta of the thinktank Centre for Research on Energy and Clean Air.
Also a synchrotron for Africa, how such a project would give a boost to scientific development across the continent, with Marielle Agbahoungbata from the X-tech Lab in Seme City in Benin.
Moriba Jah, who leads the Computational Astronautical Sciences and Technologies Group, at the University of Texas, in Austin, tells us what he saw when an exploding Russian satellite sent a shower of debris into the path of the International Space Station.
And the animals that carry SARS-Cov-2, an analysis from Barbara Han of the Cary Institute of Ecosystem Studies in New York shows there are many more than previously thought.

And, Cats started hanging out with humans thousands of years ago, and nowadays these fluffy, lovable pets are found in many of our homes. But there’s no doubt lots of them still have keen hunting instincts - witness all the birds and small mammals they kill each year.
CrowdScience listener Rachel started wondering whether her cat Eva could fend for herself while watching her uncoordinated swipes at a toy on a string, and seeing her fall off the sofa. Even though Eva was once a stray, she now lives entirely indoors, and it's hard to imagine her holding her own back on the mean streets. But could this pampered pet recover her survival instincts? Or would she go hungry, or fall foul of other cats or predators?
Cat behaviour expert Roger Tabor is on hand with answers. His pioneering ‘cat-navs’ shine a light on what cats get up to inside and outside the home: we meet one of his subjects, a tiny cat with a fierce personality. Roger explains how a cat’s survival toolkit depends on their sex, breed, and above all their early life. Environment matters, too, so in Japan, where Rachel and her pet cat live, we visit a cat shelter to learn about the day-to-day challenges stray cats face
And just how ‘domestic’ are our cats, anyway? How different are they from their wildcat cousins, and how did they come to be our companions in the first place? It turns out beguiling humans might be even more of a survival trick than hunting.
