Engineers have developed a new soft, flexible device that makes robots move by expanding and contracting -- just like a human muscle. To demonstrate their new device, called an actuator, the researchers used it to create a cylindrical, worm-like soft robot and an artificial bicep. In experiments, the cylindrical soft robot navigated the tight, hairpin curves of a narrow pipe-like environment, and the bicep was able to lift a 500-gram weight 5,000 times in a row without failing.

Neuroprostheses allow the nervous system of a patient who has suffered an injury to connect with mechanical devices that replace paralyzed or amputated limbs. A study demonstrates in animal models how EGNITE, a derivative of graphene, allows the creation of smaller electrodes, which can interact more selectively with the nerves they stimulate, thus improving the efficacy of the prostheses.

Researchers have achieved a significant breakthrough in quantum materials, potentially setting the stage for advancements in topological superconductivity and robust quantum computing.

Scientists developed and tested new artificial intelligence (AI) tools tailored to digital pathology--a rapidly growing field that uses high-resolution digital images created from tissue samples to help diagnose disease and guide treatment.

Children and young people are generally positive about artificial intelligence (AI) and think it should be used in modern healthcare.

Up to 60% of near-Earth objects could be dark comets, mysterious asteroids that orbit the sun in our solar system that likely contain or previously contained ice and could have been one route for delivering water to Earth, according to a new study.

Most known black holes are either extremely massive, like the supermassive black holes that lie at the cores of large galaxies, or relatively lightweight, with a mass of under 100 times that of the Sun. Intermediate-mass black holes (IMBHs) are scarce, however, and are considered rare 'missing links' in black hole evolution.

Solid-state batteries have several advantages: they can store more energy and are safer than batteries with liquid electrolytes. However, they do not last as long and their capacity decreases with each charge cycle. But it doesn't have to stay that way: Researchers are already on the trail of the causes.

Researchers discovered a microscopic mechanism that solves in part the outstanding performance achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs).

Researchers unveil a microstructure design guide to enhance the durability of lithium secondary batteries.

Could the universe's missing matter be hiding in a "dark" extra dimension? We now have simple ways to test this outlandish idea - and the existence of extra dimensions more generally

This new article from the Wall Street Journal describes in some detail the way the world is boycotting Israel since October 7, both because it’s defending itself and because it’s a Jewish state.

Such boycotts aren’t new, of course, as the BDS (Boycott, Divestment, and Sanctions) movement has been in swing since about 2001, but the boycotts, and calls for them, have intensified since the war in Gaza.  I’m most concerned with the call for academic boycotts, in which non-Israeli universities swear that they won’t exchange scholars or knowledge with Israeli universities. Such boycotts violate the free exchange of ideas that is the lifeblood of academia. But there are also material boycotts as well: BDS was, I believe, mainly meant to impede the exchange of goods. The academic part began around 2014, and was very quiet—until recently. And that’s what this article documents:

Click below to read the article, though it’s not archived (pdf available with judicious inquiry). I’ll give some quotes (indented):

Some examples of boycotts or calls for them:

When an ethics committee at Ghent University in Belgium recommended terminating all research collaborations with Israeli institutions in late May, Israeli computational biologist Eran Segal didn’t see it coming.

The sciences had seen little impact from global boycott movements, even months into the war, and Segal’s work had nothing to do with the Israeli military effort. The university’s research collaborations, the Ghent committee noted, include research on autism, Alzheimer’s disease, water purification and sustainable agriculture.

. . . Israelis are finding they are no longer welcome at many European universities, including participating in scientific collaborations. Their participation in cultural institutions and defense trade shows is increasingly becoming taboo.

Ghent University is, of course, where my philosopher colleague Maarten Boudry works. He’s vehemently opposed to such boycotts, and has decried them in Belgian and Dutch magazines and newspapers.

Below is an example of Israel being booted out of international meetings, though this one has little to do with academia:

Lidor Madmoni, chief executive of a small Israeli defense startup, prepared for months for a June international weapons show in Paris. The conference, Eurosatory, would be a rare opportunity for his small staff to expand their business, he said. Then came an email informing him that, because of a French court decision, his company was prohibited from attending.

“We have the obligation to block your access to the exhibition starting tomorrow,” the organizers said on the eve of the event, citing court orders that followed a French defense ministry ban issued in response to Israeli military operations in Rafah, the Gaza city where more than one million people had sought refuge.

The French decisions “shocked the entire community” of Israeli defense technology companies, said Noemie Alliel, managing director in Israel for Starburst Aerospace, an international consulting firm that develops and invests in startups in aerospace and defense. Conference organizers said they had appealed to overturn the court decision and told Israeli companies in an email that they were doing all that they could to enable them to attend.

. . . The Israeli defense-exports sector—flourishing before the war, with a record $13 billion in sales in 2023—got wind in March that it could be a target, when Chile barred Israeli companies from taking part in Latin America’s biggest aerospace fair. The French ban followed in June.

Back to academics (my bolding):

When the war began, new boycotts began to trickle in, mainly from humanities and social-science departments, said Netta Barak-Corren, a law professor who heads an antiboycott task force formed during the war at the Hebrew University in Jerusalem.

The boycotts began to widen around two months ago, spreading to the hard sciences and to the university level—“universitywide movements and more importantly decisions to cut all ties with Israeli universities and Israeli academics,” she said.

More than 20 universities in Europe and Canada have adopted such bans, she said.

O Canada!  And from Europe:

An Israeli student who was preparing to study at the University of Helsinki said she was already looking for housing in Finland—until the school told her in May that it had suspended its exchange agreements with Israeli universities.

The University of Helsinki stopped sending students to Israel after Oct. 7 and decided to suspend exchanges in May to express its concern about the conflict, said Minna Koutaniemi, the head of the school’s international exchange services. The university doesn’t intend to restrict its researchers from collaborating with Israelis, she said.

From the U.S. (this “ban” may be rescinded):

Boycotts are gaining traction across the academic spectrum. Cultural Critique, a journal published by the University of Minnesota Press, told an Israeli sociologist in May that his essay was barred from consideration because, they believed, he was affiliated with an Israeli institution.

The journal told the scholar that it follows BDS guidelines, “which include ‘withdrawing support from Israel’s…cultural and academic institutions’.”

Cultural Critique subsequently apologized for excluding the article on the basis of the scholar’s academic affiliation and amended its website to say that submissions would be evaluated “without regard to the identity and affiliation of the author.” It invited the scholar to resubmit.

Authors participate as well:

. . . some creative artists abroad are cutting themselves off from Israel. Since the start of the war, a few dozen authors, most of them American, have refused to have their books translated into Hebrew and sold in Israel, said Efrat Lev, the foreign-rights director at the Deborah Harris Agency in Israel, a literary agency.

One author who had worked with the agency and wrote a young-adult book focusing on queer acceptance refused to publish a second book in Israel, although a contract had already been signed and a translation to Hebrew was under way, said Lev.

“I felt that it was an important book for Israeli kids who are experiencing similar experiences,” she said. “This broke my heart.”

Better to demonize Israel than to help gay Israeli kids!

Academic boycotts seem to me worthless; indeed, they’re counterproductive because they divide a worldwide academic community and impede the dissemination of knowledge.  The University of Chicago issued this statement when Bob Zimmer was President:

On December 22, 2013, the University of Chicago released the following statement on the subject of academic boycotts:

“The University of Chicago has from its founding held as its highest value the free and open pursuit of inquiry. Faculty and students must be free to pursue their research and education around the world and to form collaborations both inside and outside of the academy, encouraging engagement with the widest spectrum of views. For this reason, we oppose boycotts of academic institutions or scholars in any region of the world, and oppose recent actions by academic societies to boycott Israeli institutions.”

It’s not rocket science!  But people, including academics who should know better, are hell-bent on punishing Israel and, of course, those uppity Jews who defended themselves against Hamas.  As Dorian Abbot also pointed out, such boycotts violate the Mertonian Academic Norms:

Boycotting Israeli academics is an unacceptable violation of the Mertonian Scientific Norm of universalism.https://t.co/o83TlXF1jU

— Dorian Schuyler Abbot (@DorianAbbot) July 10, 2024

You can see those norms here, which were given by sociologist Thomas Merton as “the four norms of good scientific research. . . . These norms are communism, universalism, disinterestedness, and organized skepticism.”  The one Dorian refers to is the second:

• “universalism: scientific validity is independent of the sociopolitical status/personal attributes of its participants.”

Ergo the status of “being Israeli” has no bearing on whether science should be exchanged or impeded.  Academic boycotts are, to use the argot, stupid.
