How long should we be investing in technology development for ecosystem conservation? When should we divert our funding to other conservation actions? We try to answer these questions with POMDPs: www.pnas.org/doi/10.1073/...

What information is most useful to make better decisions based on a model? @katehelmstedt.bsky.social explains how Value of Information can inform which marine invasive species should be monitored in Antarctica AND which uncertainties in our ecosystem models should we be resolving? #ICCB2025

Strength to all trans women today. The bigots are out in force, but always remember their hate says everything about them not you. Trans women are women, and a bigot is always a bigot.

Does US science have a future in Antarctica? Trump cuts threaten to cancel fieldwork and more Funding for the National Science Foundation, which finances research at US bases on the icy continent, has already been reduced, and the agency faces steeper cuts soon.

The US has three bases in Antarctica. Besides the important science done there, they're a proxy for geopolitical power. China just built its fifth base in Antarctica, so if the US pulls back, guess who will take over?

A player who has shared the most votes with a jury member is ~37% more likely to get their vote. And more votes, more likely. At this stage, Kaelan has the highest jury favorability, and Myles is critically low.

This is a strong indicator, but not deterministic. A few more things 🧡 1/

Legendary ABC chief election analyst Antony Green to step down The ABC's 2025 federal election coverage will be the last to feature Antony Green AO in an on-air role, with the chief election analyst stepping down after more than 30 years.

For a long time I've joked that Antony Green is immortal and will never retire.

He is sharp, fast, funny, and it has been such a privilege to have a front row seat to the master at work for so long.

This week the ARC should release Expressions of Interest outcomes for Discovery Projects.

Should be Wed–Fri. They’re not public, so my bot cannot track them.

The ARC should email applicants, and maybe tweet(?), to say outcomes are available in RMS.

Yep, when you hear that mining is huge, remember they mean the profits are huge...

The Hospitality industry pays more wages to Australians than does mining.
