Geologists weigh in on a long-running debate about Mars: Billions of years ago, was the Red Planet warm and wet or cold and dry?

Tuberculosis (TB) is an infectious disease that kills more than a million people worldwide every year. The pathogen that causes the disease, Mycobacterium tuberculosis, is deadly in part because of its complex outer envelope, which helps it evade immune responses of infected hosts. Researchers have now developed a chemical probe to study a key component of this envelope. Their results provide a step toward finding new ways of inactivating the bacterium.

Saying one thing while feeling another is part of being human, but bottling up emotions can have serious psychological consequences like anxiety or panic attacks. To help health care providers tell the difference, a team has created a stretchable, rechargeable sticker that can detect real emotions -- by measuring things like skin temperature and heart rate -- even when users put on a brave face.

As farmers debate whether fields should be used for agriculture or solar panels, new research says the answer could be both. Scientists analyzed remote sensing and aerial imagery to study how fields have been used in California for the last 25 years. Using databases to estimate revenues and costs, they found that farmers who used a small percentage of their land for solar arrays were more financially secure per acre than those who didn't.

Where did the water we believe is on the Moon come from? Most scientists think they know the answer - from the solar wind. They believed the hydrogen atoms that make up the solar wind bombarded the lunar surface, which is made up primarily of silica. When that hydrogen hits the oxygen atoms in that silica, the oxygen is sometimes released and freed to bond with the incoming hydrogen, which in some cases creates water. But no one has ever attempted to replicate that process to prove its feasibility. A new paper by Li Hsia Yeo and their colleagues at NASA's Goddard Space Flight Center describes the first experimental evidence of that reaction.

Mounting evidence suggests there might be two separate types of the world’s fastest-growing neurological condition. Can this fresh understanding lead to much-needed new treatments?

Scientists are still trying to understand the origin of multicellular life. It emerged about 1.2 billion years ago (or even earlier, according to some debated evidence). The timing of multicellular life's appearance on Earth is not the only thing being debated; so are the mechanisms behind it. New research supports the idea that multicellular life began when single-celled bacteria started grouping together.

As far as I know, this week is some kind of pro-Palestine week, and it’s kicked off with a bang at the University of Chicago. The usual suspects, the Students for Justice in Palestine, have erected a tent accusing the administration (through President Paul Alivisatos) and the Board of Trustees of the University of guilt for “economic genocide”, failure to divest (it’s not clear from what), and complicity in the deaths of Palestinians. This is in the form of a painted tent erected in the Quad yesterday, covered with caricatures of Trustees and the President Alivisatos, many with blood running out of their eyes and mouths. Yep, it’s the old “blood libel,” and I have no compunction in calling this anti-Semitism. (See some photos below.)

Note the “red hands” drawings, which have always been a symbol of death to Jews, reflecting a Palestinian who, in 2000, held up his blood-covered hands after helping kill two Jews. They were two Israelis who lost their way and wound up by accident in Ramallah. The PA detained them, but the mob gathered and, storming the building, tore the pair to pieces:

From Honest Reporting (note: gore and murder):

What followed can only be described as a savage, barbaric lynching. The crazed mob beat and stabbed the Israelis, tore the men limb from limb and gouged out their eyes. During the attack, Mr Avrahami’s wife Hani called him on his mobile phone. Instead of being greeted as usual, an unfamiliar strange voice answered the phone : “I just killed your husband.”

As all this was happening, one man came to the window and, much to the delight of the delirious crowd below,  triumphantly held up his blood-soaked hands for all to see.

The crowd stood below, waving fists and cheering. The body of one of the soldiers was then thrown out of the window. The baying crowd rushed to attack, beating and stamping the lifeless body in a frenzy. The body of the other soldier was set on fire. One of the soldiers was later seen upside down, dangling from a rope.

The horrendous episode was not over. Within minutes of murdering the Israelis, the mob dragged the two butchered bodies to nearby Al-Manara Square, and broke out into impromptu victory celebrations.

The famous photo:

As The Canary Mission notes, “The ‘red hand’ has a decades-old violent meaning for Jews in the Middle East. It signifies the bloody history of pogroms and the slaughter of Jews.”

That said, here are photos of the “installation” erected in the Quad, probably last night (I don’t remember it from yesterday afternoon):

Approval for the installation, showing who put it up:

Paul Alivisatos, our President, called a “genocide normalizer”:

Rachel Kohler, David Rubenstein (chair of the Board) and Antonio Gracias, characterized as “ecociders”, “CEOs of blood baths”, and so on. Note all the red hands, which to me means “kill the Jews”. (Of course you could interpret it as the trustees kill Palestinians, but the red hand has never symbolized that.) Note the blood coming out of their mouths and their satanic appearance. It’s the old blood libel, put onto the Trustees.

Tom Pritzker, also a Trustee with blood running out of his mouth. He’s called a “baby killing scum” and “Epstein Scum”.  Note the red hands again:

More red hands and Satya Nadella, also on the Board of Trustees.  He was born in India, and the caricature, with dark brown skin, could be seen as racist. More red hands.

Finally, trustee Michele Kang, also with blood coming from every orifice.

As I said, this was erected by the Students for Justice in Palestine, the major contributor to antisemitism on our campus. I have noted this in a 2024 letter to the Chicago Maroon and have called for a reassessment of their status as a Recognized Student Organization. From my letter:

Has the time come to ask whether the activism of Students for Justice in Palestine (SJP) belongs on our campus? It’s not the morally reprehensible things they say that brings this question to the fore, as their speech is protected, but how they behave: in a way that violates campus rules and disrupts the University’s mission.

.  . . . The continual disruption of our campus and violation of University regulations raises the question of whether SJP as a campus group is involved in these actions. If so, we should ponder whether that group should be a recognized student organization. At the very least, student organizations should enrich the mission of the University: promoting discourse and enriching our intellectual life. SJP does none of this, for their mission seems to be purely ideological: to promote Hamas and whitewash its terrorism—as well as to erase the state of Israel—all through disrupting campus activity. If it is to remain, it should at least desist from violating University regulations.

In fact, SJP did not desist from violating University regulations, and was given a slap on the wrist: an “official warning” that further “discipline” (LOL) would be enacted should SJP violate university regulations. This tent, since it was approved, is not a violation, but if the past is any guide, there will be more violations. And the University, which has other problems, won’t do anything.

Note that the University has already affirmed that it’s not divesting from anything, so this is purely performative, and I see it as an act of hatred and antisemitism. That, of course, is within the purview of the First Amendment, and although this kind of thuggery makes me queasy, we Jews have been subject to this for millennia and we’re not going to be put off or scared by it now.

It’s going to be a rough spring.  SJP knows that it’s lost the war, both in Gaza and on campus, and that will simply make them more active and more hateful. I trust that the Jewish students will respond with messages that aren’t hateful, but simply call for the return of the remaining hostages and embody the phrase “Am Yisrael chai” (“The people of Israel live.”)

UPDATE:  We have high winds here today, and apparently the tent blew down. Here’s a photo of the remnants. I’m sure it will be put up again.

Malgorzata, who lost many of her family in the Holocaust, has been arguing with me for several years about whether stuff like this constitutes free speech. I think it does since it doesn’t violate how our courts have construed the First Amendment, but she differs and thinks installations like this should be banned. I will reproduce with permission what she said to me when we discussed this installation this morning:

You see, Jerry, that’s why I’m definitely not a free speech absolutist. As somebody famous (I don’t remember who) said: the Holocaust didn’t start with Auschwitz, it started with words. OK, the ground was fertile, hatred of Jews was very popular for centuries, and smaller orgies of murders were done in many places. The words which are spoken now, the pictures which are shown (like this installation in your University), can very easily morph into violence (in some places it already has) and to greater and more organized violence. In Rwanda they needed the radio dehumanizing Tutsis for a few months before they went over to calling for the murder of Tutsis. The ground was prepared and people started the mass murder with joy. It’s always easier to give rise to hatred and violence than to love and tolerance. Good ideas always lose against murderous ideas.

 

It’s not a good time for Jews and not a good time for Western civilization. The monsters of barbarism are awake again and many people are embracing them.
