This new year starts a new chapter for me: I’ve moved back to Canada and made the jump from academia to engineering consulting. Today was my first day in the office, bringing my different experiences together in my new role as a coastal engineer.

The U.S. Is Funding Fewer Grants in Every Area of Science and Medicine (Gift Article) A quiet policy change means the government is making fewer bets on long-term science.

The impacts of this decrease in both the number and amount of NIH and NSF funding will be felt for generations, but props to the NIH and NSF program managers and support staff who got this many grants and this much funding out the door under very difficult circumstances.

Caltech has recommended that international scholars on H-1B visas (like myself) not leave the US.

I'm very grateful to @earthsciencewomen.bsky.social and the volunteers that moderate the list, and the community members that contribute. Thanks to all of you!

I haven't looked into whether there are differences based on location, subject area, etc. (and I'm not currently planning to)

That said, I think this figure is instructive. It might be too early to say whether the 2025-2026 job cycle is going to be "normal" or not, but so far it seems to be within the general range of other cycles. But, to me, it is clear that the 2024-2025 job cycle was not normal.

Since everything is crowd-sourced, year-to-year variability reflects not just the job market, but also people's interaction with the list, visibility of postings, moderation choices (e.g., when to rollover to a new year-cycle, etc.), and other factorsβ€”so I wouldn't read much into direct comparisons.

Here, I'm just plotting the dates jobs were added to the "Tenure Track/Permanent jobs" for each of the job-search cycles going back to 2019-2020.

The list is a really excellent community resource of crowd-sourced Tenure Track/Permanent jobs, Non-Tenure Track Faculty, and Postdoc positions hosted by @earthsciencewomen.bsky.social. It contains postings worldwide, but is mostly US-centric.

Line chart showing the cumulative number of Earth and Environmental Science faculty job postings by date added to the ESWN Jobs List for each hiring cycle from 2019–2020 through 2025–2026. The x-axis shows dates from April to August of the following year, and the y-axis shows the number of jobs (0–450). Each hiring cycle is represented by a line: earlier years (2019–2020 through 2024–2025) appear in progressively darker shades of blue, and 2025–2026 in red. Most years show rapid growth in postings from September to December, with totals levelling off by spring. The line for 2024–2025 shows a decreased growth after mid-November

As a postdoc on the job market, I've been worried about the impact of ongoing funding/policy uncertainties on faculty positions. So I decided to compare the progression of faculty jobs this cycle to previous years based on positions posted to eswnonline.org/online/earth...

Does anyone have good suggestions for where to find these foreign research jobs? The job search email listservs I am already on tend to be somewhat (though not entirely) US-centric, so I wonder if there are others I should subscribe to to cast a wider net?

Saw this article on my feed today, and had to come back and find your post so I could share:

The article claims that it's not about harder hits (fitting with your point re moment of inertia), it's about better aim.

Once Againβ€”Tidal Friction

1. Introduction
In 1920 it appeared that Jeffreys had solved the problem of tidal dissipation. We have gone backwards ever since.

I definitely understand the whole "only candidates who are selected to move on in the process will be contacted" thing. But if I have to make a government/state/provincial account to even submit an application, there should be a portal where I can check application status.
