🏝️🐜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.🐜🏝️

“Insects are essential for the environment,” said @umdentomology.bsky.social's Evan Economo. “As scientists, we need to play our part in their protection.”

Read about Evan's novel approach to studying ant populations, which revealed signs of decline in 79% of species found only in Fiji ⤵️ #BugSky

🚨 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"

The National Academies' response to the EPA's proposed removal of the endangerment finding is out today. It does not mince words about the effect of GHGs on the climate. Kudos to the authors.

How do scientists push back against autocratic, anti-science ideologies?

The "Anti-Autocracy Handbook: The Scholars’ Guide to Navigating Democratic Backsliding" provides some insights on what can be done, from lower risk to extreme risk groups:

🔬🪲An approach for long term mgmt of #EAB has been to introduce parasitic wasps to the US for #biocontrol. The Gruner Lab monitors the effectiveness of this approach one log at a time.Watch as Estes debarks trees to assess the presence of EAB larvae & the extent to which they have been parasitized.🪲🔬

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.

Since April 4, #SCOTUS has issued 15 rulings on 17 emergency applications filed by Trump (three birthright citizenship apps were consolidated).

It has granted relief to Trump ... in all 15 rulings.

It has written majority opinions in only 3.

Today's order is the 7th with no explanation *at all.*

Here we go again: Over an acerbic dissenting opinion by Justice Sotomayor (joined in full by Justices Kagan and Jackson), #SCOTUS, with no explanation, grants a stay in the Department of Education RIFs case—effectively clearing the way for the Trump administration to dismantle much of the agency:

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.

Empty shelves, trucking layoffs lead to a summer recession in Apollo's shocking trade fight timeline
U.S. consumers could start to notice trade-related shortages in their local stores next month, according to Apollo.

If you, like me, had you NSF granted terminated, here’s what I learned from a hopeful meeting with my VP of research:
1. We have 30 days to act! Meet with your admin asap
2. APPEAL: Everyone can appeal! It must go through your institution, there’s a template, sent registered mail. My VP told me ⬇️

I’m so angry & heart broken. My NSF CAREER grant was stolen today; dream project supporting science teachers/students as climate justice action researchers, tackling urban heat. Truly transformative, the culmination of my life’s work, we won’t stop, not in this climate crisis. Gonna fight like hell!
