Editor's note

A chorus of alarming headlines about the coming of designer babies has always followed every advance in reproductive technology, beginning with the introduction of IVF in 1978. That happened yet again with the recent announcement of the gene-edited Chinese twins. Epidemiologist Cecile Janssens explains why designer babies with complex traits, like intelligence, are almost impossible to create.

Oil prices are also making headlines. OPEC’s announcement that it will cut global daily oil production by 1.2 million barrels to boost prices may make it look like a unified powerhouse that dictates what crude oil costs. That’s not the case, argues energy historian Gregory Brew.

Seaweed is a diet staple all over the world, and a key source of the essential mineral iodine. However, researchers have now found that although the effects of climate change will see the plant thrive in future acidic oceans, its nutritional content will change substantially. Georgina Brennan, Dong Xu and Naihao Ye set out their research and what this means for the future health of billions of people.
