🏝️🐜A new study out by Dr. Evan Economo and colleagues reveals a decline in Fiji’s native ant species. With insects playing a crucial role in ecosystems, this research is key to understanding insect populations and guiding conservation efforts.🐜🏝️

🚨 NEW: Climate change is already causing 30,000 deaths per year - a global annual economic loss of $100-350B USD - but the true damage is probably 10x higher. Out TODAY in Nature Climate Change: the first systematic look at the science of "health impact attribution" 🔓 www.nature.com/articles/s41...
"Health losses attributed to anthropogenic climate change," a brief communication in the journal Nature Climate Change. There's a map showing regions of the world, and pie charts of relevant studies as they apply to different health impacts like "heat-related deaths" and "maternal and child health"

Had to try this out with insects and HOO BOY is this embarrassing.
ChatGPT's response to the prompt "Create a detailed diagram of generalized insect external anatomy, labelling all the major anatomical features such as body regions, mouthparts, and leg segments." It produced a scientific-esque drawing of a wasp-like creature with various incorrect labels. "Compound eye" points to the labrum, "mandible" points to the labial palps, maxilla points to the front tarsi, palpus points to the front pretarsus, coxa and trochanter point to the same on a very deformed middle leg, femur also points to a tarsus, tibia points to the hind pretarsus, head points to the thorax, and thorax points to the wings. The only accurate label is for the abdomen, and then a "cuticle" label that points to the end of the abdomen, which is technically sort of correct but misleading, as the cuticle covers the entire body.

Well, it's official. We just received notice that all authors on the Sixth National Climate Assessment have just been released from their roles. The NCA is a vital, Congressionally mandated resource for our nation as we prepare for the impacts of climate change. This is a huge loss.
NCA6 Update
April 28, 2025 
Dear NCA6 Participants, 

Thank you for your participation in the 6th National Climate Assessment. At this time, the scope of the NCA6 is currently being reevaluated in accordance with the Global Change Research Act of 1990. We are now releasing all current assessment participants from their roles. As plans develop for the assessment, there may be future opportunities to contribute or engage. 

Thank you for your service.

Happy to walk anyone through this. Our grants are proposed work. We often budget for things like salaries, student tuition, and equipment and consumables (in my field). We work on tight margins - we're often asked to "trim" or modify budgets because program officers try to spread the money.
