ProMED is one of the most useful scientific tools you’ve never heard of. It’s a global surveillance system of infectious disease outbreaks which is available, for free, to researchers and the public alike. But ISID, the society which runs the platform, claim they have run out of money to support ProMED and will be switching to a subscription service, against the wishes of both users and staff. ProMED editor Marjorie Pollak tells Science in Action about the vital service ProMED has played in pandemic monitoring – including the very first COVID outbreaks - and ISID boss Linda MacKinnon considers what’s next for the platform.

From wildfires in Europe to droughts in Africa, we have covered every kind of environmental disaster across most of the globe in the space of the past few weeks. To complete the distressing bucket list of climate extremes, we’re talking to sea ice expert Caroline Holmes on the concerning forecast for Antarctica.

Despite these terrestrial challenges, NASA is still trying to defend Earth against nearby objects which might hit us from space. The Double Asteroid Redirection Test (DART) was launched at the asteroid Dimorphos back in in November 2021 and, a few weeks ago, the Hubble space telescope observed a swarm of boulders shed by Dimorphos post-impact. Some UK newspapers are concerned about their trajectory, but astronomer Dave Jewitt is here to calm us all down.
