Today I have something really special for you guys! Not too far from the caiman I posted recently, I found something MIND BLOWING

This is a butterfly pupa, and it mimics the head of a snake. And not just any snake, but specifically the head of a boa snake!!! Probably Opsiphanes, an owlet butterfly.

NEW!🦠🌡️ : What makes a "dengue year" like 2023-24? It's hard to pin down an answer unless you can homogenize out all the spatial variation and temporal trends. But once you do, the answer is pretty clean: dengue years are hot years.

SFSU offers buyouts to all tenure-track and tenured faculty
The Voluntary Separation Incentive Program is a “balancing act,” where there is a stronger incentive for tenured and tenure-track faculty to retire and open up room to hire back lecturer faculty.

McGill is hiring scholars from outside Canada! The Canada Impact+ Research Chairs (Impact+) Program is designed to attract world-leading researchers whose work addresses critical national and global challenges. Review of applications begins 1/16/26. www.mcgill.ca/research/res...
Only candidates who are internationally based (both working and residing outside of Canada) at the time of the time of the first Impact+ Program intake application deadline are eligible to apply. Impact+ candidates must have a recent track record of research accomplishments and significant interest in making new contributions to Canada in the strategic research priority areas. Successful Impact+ candidates will be appointed to a tenure-track position at the rank of Full Professor, or as an Associate Professor with a promotion to Full Professor within two years of starting their appointment in the academic unit(s) that best fits their area of academic interest and expertise. Impact+ chairholders are expected to drive the translation of discoveries into applications, commercialization and social and economic benefits for Canada and the world, while also developing the next generation of highly qualified personnel in the following priority areas: Advanced digital technologies (AI, quantum, cybersecurity) Health, including biotechnology Clean technology and resource value chains Environment, climate resilience, and the Arctic Food and water security Democratic and community resilience Manufacturing and advanced materials Defence and dual-use technologies

NYC Council passes law that would require landlords to provide cooling systems capable of maintaining 78°F "in rooms in which tenants sleep, upon the request of the tenant."

Cooling season would run from June 15 - September 15. Bill is currently on Mayor's desk waiting to be signed. (1/2)

The UNC system just released its final policy on mandatory syllabi disclosure, stating that syllabi are university (not faculty) IP and certain course info must be posted on new, publicly searchable databases before every semester.

More states are requiring public colleges to make class syllabi available to the masses. Proponents say these measures boost higher ed’s credibility, while faculty fear being targeted.

The International Monetary Fund asked me to review the literature on migration economics to draw lessons for low-income countries.

In a new @iza.org paper, I argue that policy for the 21st century must discard four outdated ideas.

www.iza.org/publications...

🧵 thread—>
1. Less skilled labor is abundant. 2. Skilled emigration is a brain drain. 3. Development substitutes for migration. 4. Migration substitutes for failing development, but doesn't cause development.

Here is a map of the affected countries (excluding Tonga), to give you a sense of how much this new ban restricts immigration from Africa in particular.

Of the newly-added country, Nigeria faces the largest impact, with tens of thousands of visas issued every year to Nigerians.
