To end a rough week on a high note, here is  “Crazy Opossum Lady” showing you how to massage your marsupial.

Reader Rosemary sent me this video made by M. E. Pearl. It’s hilarious!  She does this tongue in cheek, of course, but her devotion to these lovely creatures is genuine, and she has many funny videos on possums, always emphasizing that they are harmless (indeed, helpful) and should not be killed.  There are dozens of possum videos on her website.

Do note that opossums do not live very long: as Wikipedia notes:

The Virginia opossum has a maximal lifespan in the wild of only about two years. Even in captivity, opossums live only about four years. The rapid senescence of opossums is thought to reflect the fact that they have few defenses against predators; given that they would have little prospect of living very long regardless, they are not under selective pressure to develop biochemical mechanisms to enable a long lifespan.

Of course, there might be selection to increase the lifespan by evolving antipredator defenses, but given that reproductive senescence may have already evolved, so they lose their ability to reproduce by a certain age (viz,. menopause in human females), those defenses might not include a longer life.

This is one compliant possum.  I hope it enjoyed the massage!

Researchers have made significant inroads in understanding how nanoplastics and per- and polyfluoroalkyl substances (PFAS) -- commonly known as forever chemicals -- disrupt biomolecular structure and function. The work shows that the compounds can alter proteins found in human breast milk and infant formulas -- potentially causing developmental issues downstream.

Researchers have achieved a breakthrough in zero-field nuclear magnetic resonance spectroscopy, paving the way towards benchmarking quantum chemistry calculations.

Engineers have trained a humanoid robot to perform a variety of expressive movements, from simple dance routines to gestures like waving, high-fiving and hugging, all while maintaining a steady gait on diverse terrains. This work marks a step towards building robots that perform more complex and human-like motions.

Without additional regulation, burning ammonia in ship engines could cause serious impacts on air quality that could result in more than 600,000 additional premature deaths per year, according to new research.

Canada has been proving itself the most spineless country in the world when it comes to dealing with illegal campus activism (or other performative activism). Take, for example, The University of Windsor in Ontario, which until now I thought was a respectable university. They’ve had an encampment for two months, and the students, as usual, made a number of demands before they’d take it down.  But in a sickening display of cowardice, Windsor University made a deal with the students, one in which the University capitulates to a number of ridiculous demands. I receive a copy of what is purported to be the agreement, and will send it to you if you ask (it’s too long to reproduce here). But I’ll put some of the agreements below.

UPDATE: I now realized that the agreement is linked to in the CBC report (here), so I don’t need to send it to you. But the copy I received is very slightly different from that at the CBC link (the latter, for example, calls for an academic boycott of Israel, while that bit has been crossed out in what I received.)

First, though, here’s an article from the CBC news site that describes the agreement. Click headline to read:

And the story.  I’ll put below the specifics from the agreement that i was sent. Bolding is mine.

The University of Windsor says it’s reached a deal with students with a pro-Palestinian encampment that began in mid-May, and all tents will be removed from the southwestern Ontario campus within 48 hours.

“This includes peacefully ending the encampment,” the school said in a news release.

The school says the deal also includes more anti-racism initiatives, support for students impacted by the crisis in Gaza, “responsible” investing, and annual disclosures of direct and indirect public fund investments.

The agreement also involves boycotting institutional partnerships with Israeli universities until the “right of Palestinian self-determination has been realized.”

It’s the “most comprehensive and far-reaching” agreement to come out of Canadian encampment negotiations addressing issues like divestment, academic boycott and anti-Palestinian racism, the protesters said in a statement Wednesday afternoon.The encampment has been in front of the former Dillon Hall since May 13.

Negotiations between the two sides have been going on for four weeks, the group says.

“This deal presents to the students, staff, faculty and community as a whole that the university is willing to take solid steps towards a more transparent and just investment system, and rebuilding Gaza,” said Jana Alrifai, a spokesperson for the protest.

“It is a recognition of its past shortcomings and a commitment to betterment. Most importantly, this would have never happened without the fight and steadfastness of the student movement.”

Here are some other details in the agreement:

• The university will establish anti-Palestinian racism training and education, which will be recommended for faculty, staff and students. The training will be mandatory for the leadership team and board of governors.
• The university has 30 days to set up an anti-oppression website, which will include third-party information and resources on anti-Arab racism, anti-Palestinian racism and Islamophobia.
• Students who part of the encampment won’t get any academic or employment sanctions for participating in or supporting the encampment.

The protesters will hold a 5 p.m. ET news conference on Wednesday.

Their encampment is among numerous ones set up on Canadian campuses since April, related to the Israel-Hamas war that began in October. Most of the encampments have since come down.

On Wednesday, an encampment at Montreal’s McGill University was dismantled as police, some wearing riot gear, and others on bicycles and on horseback, descended near the campus after the university served two eviction notices to protesters.

But we’re talking not about McGill but about Windsor.  As I said, I was sent a copy via an email that said this was the agreement signed by both sides, and will show you a bit of what is in it. If you want to see the whole agreement, go here.

Clicking on the heading will take you to the agreement linked to the CBC report, but the quotes I give below come from what I was sent—with the exception of the call for an academic boycott of Israel (it’s in the CBC linked copy but not in what I got). I cannot vouch for which copy of the agreement is the final one, but there’s almost no difference between them.

And some stuff they agreed on.  CONTENT WARNING:  ARRANT COWARDICE BY CANADIAN ADMINISTRATORS:

The University of Windsor is in the process of developing its first-ever anti-racism policy. A central feature of the policy will be a focus on identity-based oppression, including anti-Arab racism, anti-Palestinian racism and Islamophobia. The University will use its best efforts to complete the process by December 31, 2024. The University commits to including Palestinian, Arab and Muslim voices as part of the policy consultation. Regular updates will be provided on the Vice-President, People, Equity andInclusion’s website.

The University commits to establishing an anti-oppression website within 30 days of the ratification of this agreement, which will include institutional and third party information and resources on anti-Arab racism, anti-Palestinian racism and Islamophobia, linked for the benefit of students, faculty, staff and community members

The University agrees to establish anti-Palestinian racism training and education, which will be recommended for faculty, staff and students. The training and education will be mandatory for the Executive Leadership Team and the Board of Governors members.

The University agrees to make internal research grants available for application by students and faculty on the topic of Palestine in all of its dimensions.

The University agrees that students will not receive any academic or employment sanctions for their participation in, or support for, the encampment, bearing in mind the broad protections provided by the freedoms of expression, association, and assembly

No punishments, as usual!

The University agrees to remove the Aspire Anti-Racism information sheet from its website. [JAC: I don’t know what this website said.]

The University will invest funds as required to extend the Scholars at Risk program for an additional year (to end in 2025). Future institutional support for the program beyond 2025 will be reviewed annually by the University based on the availability of funding. The University will make the securing of funding for the continuation of the Scholars at Risk program a priority in its future financial planning. The University will make special efforts to recruit Palestinian scholars who have been impacted by the occupation of Palestine and the scholasticide in Gaza.

Scholasticide!

The University will endeavour to support students impacted by global conflicts and humanitarian crises, including Palestinian students, who have demonstrated urgent housing needs during the Intersession/Summer term with residence housing.

Provide counselling services for Palestinian, Muslim and BIPOC students which will address the rise of racism and Islamophobia. Ensure the necessary resources to ensure counselling is delivered by racial-trauma-focused therapists

The university will facilitate mental health support groups for students experiencing trauma related to the ongoing occupation of Palestine, not less than quarterly.

Anything about helping Jews or Israelis, or Jewish students affected by the war or antisemitism? I don’t see it. But wait—there are TEN PAGES OF THIS STUFF. And of course Windsor has to change its investment policies to the liking of the encampers:

The University administration agrees to propose to the Board investment committee an expansion of its RI Policy to include a new section on Human Rights and International Law. The section would be modeled after Section C. Climate Change. The section would include a commitment to review the weapons manufacturing industry, with particular attention on companies involved in manufacturing arms used in conflict zones where UN human rights mechanisms or resolutions have determined that serious violations of international human rights, humanitarian or criminal law have occurred. The section would provide an opportunity for the University to develop an operational procedure for its RI Policy based on human rights and international law. This operational procedure would be grounded in United Nations resolutions on human rights situations, and the work of the United Nations High Commissioner for Human Rights, the United Nations Special Procedures and United Nations human rights commissions of inquiry as well as decisions of domestic legal bodies.

The University will prepare an annual responsible investing report, disclosing all investments in indirect, direct and pooled funds held in its Pension Fund, Endowment Fund and Working Capital Fund. The report shall be made publicly available. The first report will be published by December 31, 2024. The annual disclosure will provide a list of public companies within the indirect,direct and pooled funds and the amount of investments in each fund The annual disclosure will explain the application of the RI Policy, including the ESG factors and human rights, to the University’s investment decisions.

The University acknowledges the dire situation faced by Palestinian universities under Israeli occupation. This includes the destruction of the Palestinian universities in Gaza and the unjustified restrictions and frequent closures faced by Palestinian universities in East Jerusalem and the West Bank. The University commits to establishing or reestablishing institutional relationships with Palestinian universities, which will include research partnerships and scholarly exchanges. Within its resources, the University will assist with, and support, the restoration of post-secondary education in Gaza.

The University will recommend to the Senate that it explore the feasibility of implementing a Palestine Studies minor under the Interdisciplinary and Critical Studies Department. Courses under this program will aim to explore Palestine in all of its dimensions.

Finally, the encampers have forced the University to violate institutional neutrality and agree with the UN’s demonization of Israel.  Windsor has no fricking business to weigh in on the war or politics, for it violates institutional neutrality by taking an official University position on the war. That, of course, chills the speech of those (presumably many) who disagree with the agreement and the stuff that Windsor will say in its capitulation:

Within 72 hours of the ratification of this agreement, the University will send a letter to the Government of Canada calling for an immediate and permanent ceasefire. In the letter, it will also urge the Government of Canada to include anti-Palestinian racism within its Anti-Racism Strategy. Further, it will request that the Government of Canada should be generous in the humanitarian aid that it delivers to Palestine in order to enable Gaza to engage in reconstruction for its people, and to assist the Palestinians to realize their right to self-determination. The University will post the letter on its website.

This is in the document linked to at the CBC site, but is crossed out in the copy I was sent. If it really was agreed on, it calls for an academic boycott of Israel.

The University does not hold any active institutional academic partnerships with Israeli institutions. Because of the challenging environment for academic collaboration the University agrees to not pursue any institutional academic agreements with Israeli universities until the right of Palestinian self-determination has been realized, as determined by the United Nations, unless supported by Senate. This does not prevent individual academics at the University of Windsor from working (or collaborating) with academics in Israel.

Finally, there’s this—more taking sides in a conflict and more chilling of speech at Windsor:

For the purposes of the application of its RI Policy, the University recognizes that the United Nations, through its various bodies – including the Secretary General, the Security Council, the General Assembly, the Human Rights Council, the International Court of Justice and human rights commissions of inquiry – has found Israel, the occupying power, to be in serious violation of international law and human rights in the conduct of its occupation of Palestinian territory. It also recognizes that the UN Office of the High Commissioner for Human Rights has established an active database of companies whom it has identified are engaged with the illegal Israeli settlement enterprise in the occupied Palestinian territory.

Of course there’s bupkes about Hamas violating international law.

This whole document is simply reprehensible, a sickening display of cowardice (and antisemitism) on the part of Windsor University, which commits itself to taking the side of Hamas in the war and providing resources to Palestine and Palestinian students that aren’t offered to Israeli or Jewish students. There are plenty of initiatives against “Islamophobia,” but I don’t see a single one against antisemitism. Does Windsor do all this stuff for Israeli academics, professors, and students? Perhaps they already have similar policies in place with respect to Israel (extra counseling for Jewish students, etc.), but I doubt it.

The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range could be even further.

By constructing hexagonal metallic-mean approximants of the honeycomb lattice, scientists have linked incommensurately modulated structures and quasicrystals, two classes of aperiodic crystals. They found that a quasicrystal converges to a modulated honeycomb crystal on arranging tiles based on metallic means. This metallic-mean tiling pattern was also identified in polymer and colloidal systems in soft-matter self-assemblies, providing new insights into aperiodic crystals.

A small 3-ounce sensor capable of recording 2,400 data points of movement in just one second being tested and refined by researchers could be key in reducing the number of injuries to racehorses. Researchers used the biometric sensors to track thoroughbreds as they raced and trained at some of the top racetracks in the country. Using collected data, the team was able to identify miniscule stride changes associated with increased risk of injury, allowing intervention before a catastrophic breakdown.

PFAS, the potentially cancer-causing chemicals known as 'forever chemicals', have become an increasing concern in home drinking water. Solutions to reduce the risk of exposure range from mandated municipal-level water treatment to under-the-sink home treatment systems. But are consumers willing to foot the bill for an additional treatment system to help municipalities meet new federal drinking water regulations? Researchers found that they are, if it helps reduce the risk and fits their budget.

Dense E.coli bacteria have several similar qualities to colloidal glass. Colloids are substances made up of small particles suspended within a fluid, like ink for example. When these particles become higher in density and more packed together, they form a 'glassy state.' When researchers multiplied E.coli bacteria within a confined area, they found that they exhibited similar characteristics. More surprisingly, they also showed some other unique properties not typically found in glass-state materials. This study contributes to our understanding of glassy 'active matter,' a relatively new field of materials research which crosses physics and life science. In the long term, the researchers hope that these results will contribute to developing materials with new functional capabilities, as well as aiding our understanding of biofilms (where microorganisms stick together to form layers on surfaces) and natural bacterial colonies.
