If you are a student whose NSF GRFP application was returned without review for vague 'eligibility' reasons:
1) Let your department chair & Graduate School know. Encourage them to contact NSF & congress
2) Write to your congressional reps.
3) Write to grfp@nsf.gov to request re-consideration;

TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from OkjΓΆkull to Ok (jΓΆkull = glacier). Uncompromising wording on the bronze plaque:
"This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".

There was a mass flowering last year on BCI - seeds take a year to develop and disperse. This year there is one tree flowering - a 'late bloomer'. I am curious to see if it will set seed. There are a lot of South American Tachigali species. Only a small number of species appear to be monocarpic.

Infrared imaging shows heat levels in sun-exposed leaves of Alstonia scholaris from the Australian Wet Tropics. As climate change increases temperatures and the severity of heat waves, both natural ecosystems and agricultural plants are increasingly affected by heat. Examining heat responses at cellular, genetic, physiological, and ecosystem scales, this special issue explores how plants sense and respond to high temperatures.

As the world warms, plants in natural ecosystems and agricultural settings find ways to respond to the heat.

In a new special issue of Science, researchers examine how heat affects plants at multiple scales, from the molecular level to the biosphere. scim.ag/44cSw3Z
