Urine that has sat in the sun for a while seems to fertilise crops while warding off pests, without affecting the produce's taste

Recently, Columbia University caved into the Trump administration’s demands that unless the University reformed itself (mostly doing things to dispel the anti-Semitic climate), they would lose $400 million in federal funding. While most of the changes demanded were good ones, I object to the administration using science funding as a club to bludgeon Columbia into compliance. (On the other hand, Columbia wasn’t doing much, but why should science be the field to take the brunt?)  And Columbia’s caving led to the forced resignation of the interim President, Katrina Armstrong.

It’s no surprise, then, that the next target of the administration is that bastion of Lefty Communist Woke Socialism, Harvard University.  Yep, they’re being bludgeoned, too, and also about anti-Semitism. As the NYT reports (article archived here):

The Trump administration said on Monday that it was reviewing roughly $9 billion in federal grants and contracts awarded to Harvard, claiming that the university had allowed antisemitism to run unchecked on its campus.

In a statement on Monday, the administration said that it was examining about $256 million in contracts, as well as an additional $8.7 billion in what it described as “multiyear grant commitments.”

The announcement of the investigation suggested that Harvard had not done enough to curb antisemitism on campus but was vague about what the university could do to satisfy the Trump administration.

“While Harvard’s recent actions to curb institutionalized antisemitism — though long overdue — are welcome, there is much more that the university must do to retain the privilege of receiving federal taxpayers’ hard-earned dollars,” Josh Gruenbaum, a senior official at the General Services Administration, said in a statement.

“This administration has proven that we will take swift action to hold institutions accountable if they allow antisemitism to fester,” he added. “We will not hesitate to act if Harvard fails to do so.”

I didn’t know that, though, when I woke up this morning and found this email from the President Alan Garber, who was also an interim President after Claudine Gay’s resignation but now will be serving as a regular President until 2027.  Read what I got and you tell me: is Harvard about to cave, too? I have bolded the parts that suggest that Harvard will do what the administration wants. Again, Harvard did, I think, need to change to get rid of its antisemitic climate, but I would prefer that it do so voluntarily rather than be forced to.

I’ve bolded the parts below suggesting that Harvard is about to cut a deal with the administration:

Dear Members of the Harvard Community,

Earlier today, the federal government’s task force to combat antisemitism issued a letter putting at risk almost $9 billion in support of research at Harvard and other institutions, including hospitals in our community. If this funding is stopped, it will halt life-saving research and imperil important scientific research and innovation.

The government has informed us that they are considering this action because they are concerned that the University has not fulfilled its obligations to curb and combat antisemitic harassment. We fully embrace the important goal of combatting antisemitism, one of the most insidious forms of bigotry. Urgent action and deep resolve are needed to address this serious problem that is growing across America and around the world. It is present on our campus. I have experienced antisemitism directly, even while serving as president, and I know how damaging it can be to a student who has come to learn and make friends at a college or university.

For the past fifteen months, we have devoted considerable effort to addressing antisemitism. We have strengthened our rules and our approach to disciplining those who violate them. We have enhanced training and education on antisemitism across our campus and introduced measures to support our Jewish community and ensure student safety and security. We have launched programs to promote civil dialogue and respectful disagreement inside and outside the classroom. We have adopted many other reforms, and we will continue to combat antisemitism and to foster a campus culture that includes and supports every member of our community.

We still have much work to do. We will engage with members of the federal government’s task force to combat antisemitism to ensure that they have a full account of the work we have done and the actions we will take going forward to combat antisemitism. We resolve to take the measures that will move Harvard and its vital mission forward while protecting our community and its academic freedom. By doing so, we combat bias and intolerance as we create the conditions that foster the excellence in teaching and research that is at the core of our mission.

Much is at stake here. In longstanding partnership with the federal government, we have launched and nurtured pathbreaking research that has made countless people healthier and safer, more curious and more knowledgeable, improving their lives, their communities, and our world. But we are not perfect. Antisemitism is a critical problem that we must and will continue to address. As an institution and as a community, we acknowledge our shortcomings, pursue needed change, and build stronger bonds that enable all to thrive. Our commitment to these ends—and to the teaching and research at the heart of our University—will not waver.

Sincerely,
Alan M. Garber

I cannot interpret this other than as Harvard capitulating to the administration’s demands. Neither the administration nor Harvard are specific here, and Harvard does admit that it still has a “serious problem” of “antisemitic harassment” (I’m not sure how pervasive the problem still is.)  Indeed, Garber says that he himself has been a victim of antisemitism.  How did that happen? The NYT suggests one explanation:

He may have been referring to a poster showing him with horns and a tail that was displayed by a student group during Harvard’s encampment last year.

There’s a lot more in the NYT piece, so have a look if you’re following the Siege of the Universities.  This is only the beginning!

It’s SHARK DAY!  Today’s shark photos come from Owen Jones, Professor of Law AND Professor of Biological Sciences at Vanderbilt University. Owen’s captions and IDs are indented, and you can enlarge his photos by clicking on them.

In February 2025, a friend and I joined a week-long live-aboard trip to a patch of Atlantic Ocean about 20 miles north of the Bahamas.  The purpose was to scuba dive among Tiger Sharks (Galeocerdo cuvier), so named because of they typically have dark stripes down the body.  Because the dive guides were bringing the sharks in close with chum, our main task was to neither act like nor look like dead fish.  (Which is why our bare skin, except around the lips, was all covered in dark neoprene – and also why we would actively turn to confront incoming sharks, as a display of vitality and all around non-dead-edness.)

Tiger Sharks, which can grow to approximately 17 feet, and weigh up to 2,000 pounds, have the widest diet of all sharks.  And their especially saw-capable teeth enable them to cut through sea turtles in a way that other sharks can’t.

On one hand, Tiger Sharks are #2, after only Great White Sharks, in recorded fatal attacks on humans.  On the other hand, the absolute number of attacks is quite small.  And Tiger Sharks only rarely attack divers.

At a different location, we had the hoped-for pleasure of seeing Great Hammerheads (Sphyrna mokarran).  They grow to approximately 14 feet and 1200 pounds.  They are the largest of the hammerhead species, and are considered critically endangered.  They are generally shy, and are not considered a major threat to humans.

Your correspondent is on the right in these last two shots.

Sharks like these are absolutely magnificent creatures.  Powerful, nimble, and well-adapted (at least to a world before industrial-scale shark-finning).

An invaluable resource is being starved to death with no scientific or ethical justification

The post The tragic termination of the Diabetes Prevention Program Outcomes Study first appeared on Science-Based Medicine.

Could microbes survive in the permanently shadowed regions (PSRs) of the Moon? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from the United States and Canada investigated the likelihood of long-term survival for microbes in the PSR areas of the Moon, which are craters located at the poles that don’t see sunlight due to the Moon’s small axial tilt. This study has the potential to help researchers better understand unlikely locations where they could find life as we know it throughout the solar system.

What can a sample return mission from Jupiter’s volcanic moon, Io, teach scientists about planetary and satellite (moon) formation and evolution? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as an international team of more than two dozen scientists discussed the benefits and challenges of a mission to Io with the goal of sampling its volcanic plumes that eject from its surface on a regular basis.

It’s getting a little harder to be the first humans to achieve something but, if all goes to plan, a team of four private astronauts are expected to head off into a polar orbit around Earth aboard the SpaceX Dragon capsule today (31 March) at 9:46pm ET and take the crew over the North and South Poles of Earth. Financed by Chun Wang, a Malta-based investor, they are planning a series of experiments, including attempting to grow oyster mushrooms in microgravity, which could eventually become a source of food for space missions.

After a container ship struck and destroyed the Francis Scott Key Bridge in Baltimore, Maryland, researchers began calculating the risks of similar catastrophic incidents for other US bridges – and they’re surprisingly high

Astronomers suspect that Europa has cryovolcanoes, regions where briny water could erupt through Europa's ice shell, throwing water—and hopefully organic molecules—into space. NASA's Europa Clipper and ESA's JUICE mission are on their way and will be able to scan the surface of the icy moon for signs of cryovolcanism. What should they be looking for? Pockets of brine just below the surface could be active for 60,000 years and should be warmer than their surroundings.

AI mental health apps may offer a cheap and accessible way to fill the gaps in the overstretched U.S. mental health care system, but ethics experts warn that we need to be thoughtful about how we use them, especially with children.

Researchers have developed an innovative solution to a pressing environmental challenge: removing and destroying per- and polyfluoroalkyl substances (PFAS), commonly called 'forever chemicals.' A new study unveils a method that not only eliminates PFAS from water systems but also transforms waste into high-value graphene, offering a cost-effective and sustainable approach to environmental remediation.

Subsurface Habitats on the Moon and Mars Could Be Grown Using Mushrooms and Inflatable Robots

One of the first verified predictions of general relativity is the gravitational deflection of starlight. The effect was [first observed in 1919 during a total solar eclipse.](https://briankoberlein.com/post/einstein-and-eddington/) Since stars appear as points of light, the effect is seen as an apparent shift in the position of stars near the eclipse. But the effect happens more generally. If a distant galaxy is obscured by a closer one, some of the distant light is gravitationally lensed around the closer galaxy, giving us a warped and distorted view of the faraway stars. This effect can also magnify the distant galaxy, making its light appear brighter, and we have used this effect to observe some of the most distant stars in the Universe.

In-situ resource utilization will likely play a major role in any future long-term settlement of the Moon. However, designing such a system in advance with our current level of knowledge will prove difficult, mainly because there's so much uncertainty around both the availability of those resources and the efficacy of the processes used to extract them. Luckily, researchers have tools that can try to deal with both of those uncertainties - statistical modeling. A team from Imperial College London, the University of Munich, and the Luxembourg Institue of Science and Technology recently released a pre-print paper on arXiv that uses a well-known statistical modeling method known as Monte Carlo simulation to try to assess what type of ISRU plan would be best for use on the Moon.

Even though Jupiter's moon Io is considered the most volcanically active world in the Solar System, Venus actually has more volcanoes and volcanic features on its surface. For a long time, scientists thought that most of these features and volcanoes were ancient remnants of the planet's geological past. However, newer research shows that Venus is still volcanically active.

Someone sent me this tweet a few days ago, and I was unsure about whether this was any kind of violation of University policy.  As far as I gather, this was posted on the inside of a chemistry professor’s office, facing outwards.

University of Chicago – Outside a chemistry professor’s classroom, a sign filled with propaganda reads, “DEPORT ISRAELIS.”

This is blatant antisemitism and xenophobia which is completely unacceptable, @UChicago. An investigation is needed. pic.twitter.com/wGer8vjX9f

Here’s a photo from that tweet, but all I can make out in it is “Israel murdered 18,000 children” (Hamas’s figures, and probably grossly untrue) as well as “Israel must pay for the murders and destruction” and “DEPORT ISRAELIS.” If you can read more of it, please decipher in the comments. 

Anyway, I sent the tweet around to our local free speech group and asked if this was a violation of University rules.  This morning someone said that this kind of thing is indeed allowed, though you’re not allowed to display flags in your office (some wonky rule). A watermelon, though, does nicely as a substitute for the Palestinian flag. At any rate. I saw the tweet below this morning, indicating that the University of Chicago itself had apologized for the sign, which was “voluntarily” taken down, and said that it is being investigated as a possible violation of the “University’s non-discrimination policy.”

We sent a letter to the President of the University of Chicago. We’re working closely with students on the ground. This is the statement the University released today.

Let’s be clear: pressure works. Community matters. And transparency is everything.

The statement:

If this is indeed allowed behavior, then putting a sign like this inside your office, facing out, is not a violation of free speech, which is part of the Chicago Principles. On the other hand, one could argue that such a sign creates a climate of harassment towards Jewish students, which is a Title VI violation. Now that Trump is threatening to withhold money from universities for condoning anti-semitic behavior, I can see where this kind of publicity could scare our university.

I don’t know if I’ll learn any more about this, but if I do I’ll impart it below.  All I can say is that IF displaying this kind of sign is permitted by University regulations, then it’s not kosher to investigate the person who posted it (that’s chilling of speech) or to make a public statement about it. All of this hangs on the “time, place, and manner” restrictions of speech at the University here, and people aren’t sure what the policy is.

Anyway, weigh in below with your opinion.
