Time to act

Climate change is arguably the scientific and societal issue of our age. Unless drastic action is taken, Earth is likely to exceed 3 °C of warming by the end of the century, bringing with it unprecedented weather extremes, rising seas, mass extinctions and human misery. The science and the threat are clear − but the world and its leaders are proving slow to respond. This week, Nature is joining with more than 220 media outlets worldwide in Covering Climate Now, a coordinated initiative to raise the profile of climate coverage in the run up to the UN climate summit in New York on 23 September. With a growing youth climate movement calling for climate strikes, the energy and intensity of the debate is ramping up. Human ingenuity is up to the challenge — but only if societies, industries and governments resolve to act, and act now.

    Researchers should learn to travel better to mitigate their climate impacts. Institutions can help by facilitating and rewarding sustainable travel behaviour, rather than fuelling the pressure to attend conferences, say Olivier Hamant, Timothy Saunders and Virgile Viasnoff.

    How cancer cells migrate to a secondary site and become established there is not fully understood. An analysis of mouse and human cancer cells could help settle the debate about the role of the protein E-cadherin in this process.

    A US national experiment showed that a short, online, self-administered growth mindset intervention can increase adolescents’ grades and advanced course-taking, and identified the types of school that were poised to benefit the most.

    In the brains of embryonic mice, some types of progenitor (apical progenitors) can revert to earlier molecular, electrophysiological and neurogenic states when transplanted into younger hosts, whereas others cannot, highlighting progenitor-type-specific differences in fate plasticity.

    Quantum critical behaviour at the many-body localization transition in a disordered Bose–Hubbard system of bosonic rubidium atoms in an optical lattice is observed, connecting the macroscopic phenomenology of the transition to the system’s microscopic quantum correlations.

    Influenza kills up to 500,000 people annually. The influenza virus mutates to evade our immune system and occasionally changes drastically to become a new subtype that can start a pandemic.
