Rising carbon dioxide is driving a ‘global greening’ boom in plant growth. But a new study shows the world’s plants aren’t using any more water in the process. It’s a rare piece of good news that could boost the prospects of water-wise crops, but as Pep Canadell and colleagues explain, it won’t solve all of our water problems.
And today’s instalments in our series on blood look at what blood is made up of, and what happens to the components after they’re donated. And our infographic charts the history of blood transfusions - from using animal blood in the 17th century to the lifesaver it is today.
