    It's true!

    A team at the Francis Crick Institute in London used a technique called CRISPR-Cas9 to remove a gene in very early embryos. It was the first time this has been done in Britain, and the first time in the world that the technique has been used to help understand the role of genes in early human development.

    Pumpkin toadlets appear to have lost the ability to hear their own mating calls, but not (yet) lost the ability to make the calls themselves.

    The Cassini spacecraft

    The Cassini-Huygens mission came to an end when Cassini threw itself towards Saturn – to avoid contaminating any of the planet's potentially habitable moons with earthly microbes. In its lifetime Cassini produced some breathtaking images of Saturn.

    Cassiopea jellyfish

    Also known as upside-down jellyfish. They may not have brains, but according to a study of 23 individuals published this month, they do go dormant for a period at night, and when deprived of this sleep-like state, they struggle – just like sleep-deprived humans do.

    1.5ºC

    The 2016 Paris agreement set world governments the goal of keeping global warming to "well below" 2°C above the preindustrial average, with an "aspiration" of keeping it to less than 1.5°C. A study published this month in the journal Nature Geoscience says that this target is still physically possible – although there is still doubt about whether it's politically or economically viable.
