NEW: We've tracked the world's largest iceberg, A23a, and it's on the move again! It travelled along the seafloor ridge from the Filchner Ice Shelf to past South Orkney islands, pushed by currents, and is now in deeper waters en route to South Georgia.

It's time to log off. People are ingesting too much negative news, and it’s not only affecting them personally but impacting society at large. Psychology experts say you need to know your limits—and when to put down the phone.

NEW: One of the worst methane leaks ever recorded revealed. Using satellite data, scientists estimate 127,000 tonnes of methane escaped from an exploratory well in Kazakhstan. We analysed @planet satellite images to understand exactly what happened, from the blowout to its fix

I also looked at a good few streets such as 'Woodstreet' which joins the N77 outside Portlaoise. Besides from OSM, I cannot find any record of it. Officially it's the 'L26812'. There is a wood design business on the road which may explain the name on OSM. (3/3)

The reason they were disappointing is that the longest streets and roads were colloquial names such as the below. OSM refer to it as 'South Perimeter Road' whereas the actual road signs (and MapGenie) refer to it as the 'R108' (2/3)

Being a quiet New Year's Day I thought I'd take a quick look at what the longest road and street are in Ireland. I downloaded the data from geofabrik and processed it using Osmium and GDAL then ran a few SQL queries in PostGIS. The results were disappointing (1/3)

About 1.2 million people die from tuberculosis every year. Until now, however, we didn't cover this infectious disease on @OurWorldInData, it was an important gap in our publication. @salonium and @f_spooner changed this. Here is our new page on TB: https://t.co/5d892nWE1l

New paper just dropped (I think that's what you say) on Valeriepieris Circles, aka Yuxi Circles "The Valeriepieris (VP) circle is the smallest circle containing half of the world's population." It's very cool and does it for countries as well 🤓🥳⬇️ https://t.co/BpIReYTKsx
