This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

Planetary Alignment

xkcd.com/3192/
4-panel comic. (1) PERSON 1 with ponytail: The inspection revealed a few problems. Looks like your planet needs an alignment. PERSON 2: Oh? (2) PERSON 1: Yeah, your magnetic axis is 400 miles off-center from your rotational one. PERSON 2: Is that bad? (3) PERSON 1: The unbalanced magnetic field could cause radiation anomalies over the South Atlantic. Have you noticed any spacecraft equipment failures in that area? PERSON 2: There *have* been a few, actually. (4) PERSON 1: We can give you a loaner planet while yours is in the shop. Is a gas giant OK? PERSON 2: I’d *really* prefer a solid surface. PERSON 1: Sorry, it’s all we have. But it’ll just be for a few days.

‘Cancel’ comes from a Latin word meaning “to make like a lattice.”

When people needed to annul or void a document, they sometimes would mark it with crosshatches

XXXXX

which resembled a lattice.

So the document became ‘canceled.’

...we hope this post doesn’t get us that.

Almost a decade ago Emma Johnston, Tanya Monro and I appeared at The National Press Club of Australia to talk about our stories and our views of issues that impact on Women in Science. It was an amazing experience…

I will miss you Emma.

Devastating news that marine biologist, science communicator, and UniMelb VC Professor Emma Johnston has died after a short illness.
She really was an extraordinary and visionary leader, and I have no doubt she would have made a fine Chief Scientist one day.

I was searching for the arXiv reference for my recent preprint with 2 collaborators but the first hit was an AI synopsis of us as researchers 😂
An AI overview at the top of a webpage saying “Nalini Joshi, Marta Mazzocco, and Pieter Roffelsen are mathematicians known for their collaborative research on Painlevé equations and integrable systems, particularly the geometry of their solution spaces. Their published work focuses on topics such as: • Segre surfaces and geometry of the Painlevé equations: They consider a family of affine Segre surfaces associated with the q-difference sixth Painlevé equation (qPVI).”

Very sad that I felt I had no choice but to resign from The Infinite Monkey Cage - a victory for the transphobes and other bigots - I did it because so much of the media has chosen to believe the kind and empathetic people are a fiction - they are real and so often unrepresented.
This is the saddest day of my professional life. Today is not only the final recording of the latest series of The Infinite Monkey Cage, it is my last ever Monkey Cage. I never thought that I would have to leave the show. I always imagined going on until | dropped dead under the studio lights due to a brain aneurysm caused by my final attempt to understand notions of quantum gravity or the shock of being told about fly maggot infestations in the sacks of macaque monkeys. I resigned in September, after sixteen years of dedication to the show, A show that I named and helped develop over all those years. Unfortunately, my opinions outside the BBC have been considered problematic for sometime, whether it has been voicing support for the trans community, criticism of Donald Trump, numerous other outlandish opinions, including once gently criticising Stephen Fry. These things were considered to conflict with being a freelance BBC science presenter In a recent meeting where BBC Studio executives again voiced problems with me, I realised my choices. Obedience and being quieter to remain making Monkey Cage, or 'Resign and have the freedom to speak out against what I believe are injustices'. • I chose the latter. It broke my heart. I love this show and I love the audience, and it is because of the audience in particular, that this decision was so difficult to make. I kept thinking about all the extremist voices promoting hate and division. They are being given so many platforms, while voices that represent kindness, open mindedness, empathy seem to be scarcer and scarcer. I felt I couldn't pamper myself with the luxury of silence. One of my many privileges is that I am able to resign and I can speak out even if it is to the detriment of my career. I have thought a lot about my heroes, Sinead O Connor, James Baldwin, Audre Lorde, and so many more. I think of Sinead's words, "the job of an artist is to be themselves at any cost". James Baldwin said prejudice was really just a word for cowardice. Audre Lorde, viewing her life, wrote that her only regrets were her silences. I think of my father as I resign, he brought me up to believe in fairness , justice and kindness. Though my heart is broken, it is also full of fire. I apologise to our incredible listeners for my departure, your love of the show means a great deal. I am so sorry to let you down. I hope that you can understand my reasoning. I have to accept that I am not what the current BBC expects of their freelance presenters. Despite this I should add that I have always worked far more than my contracted hours to try and ensure the show was always the best it could be, as well as making myself accessible and responsive to the audience wherever and whenever I met them. Every night, we have recorded, I have been filled with determination to make the best show possible. This was not "just a job" I hope that with my departure I can be a better ally to the LGBTQ community, to the neurodivergent community, to activists fighting against those who aim to brutalise society, to those currently in prison on hunger strike, and to all those who fight for a more inclusive world. From many conversations, I know there are many Monkey Cage listeners who support these communities and activists too. The strawberry is dead. Long live the strawberry. B

The mathematical art exhibit at this week’s AustMS also featured stunning works by @mathskath.bsky.social which she has modestly omitted in her posts about it. Behold ⤵️
A hitomezashi embroidery on cream in a beige frame, with one line of red running through it. Caption: “Katherine Seaton Corner percolation (2025) Corner percolation is a mathematical constrained random walk model proposed by Bálint Tóth and investigated by Gábor Pete in 2008. More recently, it has been noted that the configurations of paths and closed loops of corner percolation are found in the centuries-old domestic stitching form hitomezashi. Whether right-angled corners are placed on the vertices of a square lattice in the mind of a twenty-first century mathematician, or lines of horizontal and vertical running stitches interact tangibly when sewn with a needle as in Edo-period Japan, the potential patterns are the same. Traditionally, lines of stitching in hitomezashi are deliberately aligned or offset from their neighbours to create designs featuring small motifs repeated periodically. However, in this piece of mathematical fibre art the parity of the digits of i has been used to place the lines of stitching randomly. The result is a design comprised of closed loops of various sizes as well as paths of stitches that begin and end on an edge of the worked area. One such path has been highlighted for the eye in scarletwork.” A black and white hitomezashi embroidery by Kath Seaton with a black frame. Its caption reads: “Katherine Seaton Crosses and crowns (2022) Placed according to a recurrence relation for binary words proposed in a paper by Carol Hayes and Katherine Seaton, the lines of stitching in this hitomezashi piece interact to form polyominoes of various sizes, all of which are Fibonacci snowflakes (of orders 0, 1, 2, 3 and 5). The reverse of the stitching, which is not accessible due to framing, displays a translated copy of the same pattern.”
