“The Zoologist’s Guide to the Galaxy: What Animals on Earth Reveal About Aliens – and Ourselves”

author Arik Karshenbaum/
book cover

By MARTIN ZEILIG “That life exists elsewhere in the universe seems almost inevitable,” Dr. Arik Kershenbaum writes in this intriguing and entertaining book.
“That we could know anything about it seems almost impossible. But my goal is to show you that we can actually say a great deal about what aliens must be like, how they live, and how they behave.”

Dr Kershenbaum is a zoologist, College Lecturer, and Fellow at Girton College, University of Cambridge, says his bio. He has researched animal vocal communication for the past ten years in Europe, Israel and the United States and has published more than 20 academic publications on the topic.

He is also a member of the international board of advisors for METI.org, a think tank on the topic of Messaging Extra Terrestrial Intelligence. Arik has done extensive field work on animal communication, following wolves around Yellowstone National Park and the forests of central Wisconsin to uncover the meaning of their different kinds of howls, as well as decoding the whistles of dolphins among the coral reefs of the Red Sea, and the songs of hyraxes in the Galilee.

Using his own trained understanding of life on Earth and Darwin’s theory of evolution—“which applies throughout the universe,” according to Dr. Kershenbaum’s book—Dr. Kershenbaum explains what alien life must be like: how these creatures will move, socialize, and communicate.

Dr. Kershenbaum agreed to do an interview with The Jewish Post & News.

JP&N: Why did you feel it necessary to write this particular book?

AK: Until recently, it was absolutely fine to restrict thoughts about alien life to science fiction. It was fun, and it was entertaining, and it didn’t have anything to do with science, or biology, or real life of any kind. All that is changing now.
Our understanding of the possibilities of life in the universe has blossomed as our technology for examining other planets has moved forward in leaps and bounds. Difficult as it is, we’re going to have to put aside the science fiction, and make a study of alien life into a well-grounded scientific discipline. And everyone should realize that the universe almost certainly is teeming with life – now we just need to find it.

But the search for extraterrestrial life isn’t enough. It’s also important to think about what that life is going to be like. What are the principles that determine how life evolves elsewhere in the universe? Will it be similar to life on Earth, or totally different?
These questions were very hypothetical as long as the chances of discovering life on other planets was remote in the extreme. Now that scientists are quietly optimistic, we all need to make an adjustment.
Fortunately, the Earth is an amazingly diverse habitat, full of life in the most surprising range of possibilities. Even if the conditions on other planets are very different from here, we have learned enough on Earth about the processes of evolution, and the forces that drive the properties of life, so we can apply those principles more generally to whatever exists on other worlds.

JP&N: Daniel Fabrycky, assistant professor of astronomy and astrophysics at the University of Chicago, has argued that “over billions of years no intelligent aliens have made it to the point of reaching Earth, meaning humanity has dismal prospects for space exploration and expansion.”
What would you say in response to Prof. Fabrycky?

AK: I think that the current climate crisis gives us a clue to how unlikely it is that humanity will survive to get the chance to explore space. It has always been thought that the process of life arising from “non-life” (i.e. a mixture of chemicals) was the limiting step in the distribution of civilizations throughout the universe.
But a more serious barrier might be the challenge of surviving rapid technological advances, without destroying ourselves through environmental destruction and war. It may be that many planets produced civilizations like ours, but they’re all dead.

However, there are many other possible explanations for why we’ve never noticed any alien civilizations. The laws of physics, as we know them, seem to make travel between the stars almost impossible. Maybe alien civilizations know things that we don’t, but maybe we’ve got things right, and aliens haven’t developed warp drive simply because it’s not possible.
As for not having received any radio or similar signals from outer space, we’ve only been looking for the last few decades – we only invented radio just over 100 years ago! – and we’ve never had funding to do a really comprehensive search for intelligent signals. I’d say that Fabrycky may be right, but that it’s too early to rule out a better possibility.

JP&N: What else would you like our readers to know about this topic?

AK: Life evolves according to the laws of biology, just like balls roll according to the laws of physics. We’ve come to understand a lot about these biological laws, and we can apply them to make predictions about life, even on other planets.
We can’t predict what colour aliens will be, but we can say a lot about the way they will interact, and solve problems like moving around, finding food, and cooperating or competing with other animals. Much of the underlying diversity of life on Earth – plants vs. animals, predators vs. prey, etc – arises as the result of common rules, and that means that this diversity is going to exist on other planets too.

“A direct biological comparison between us and alien intelligences could bring us to a more complete and more satisfying description of life in the universe. Perhaps we will be able to come to an acceptance of a wider type of humanity; one that has room for creatures that don’t look like us, no matter what planet they inhabit,” Dr. Kershenbaum writes in “The Zoologist’s Guide to the Galaxy.“

Bias in America’s Colleges Produced Modern Anti-Zionism

By HENRY SREBRNIK Jon A. Shields, Yuval Avnur, and Stephanie Muravchik, professors at the Claremont Colleges in California, have just completed a study, “Closed Classrooms? An Analysis of College Syllabi on Contentious Issues,” published July 10, 2025, that draws on a database of millions of college syllabi to explore how professors teach three of the most contentious topics: racial bias in the criminal justice system, the Israel-Palestine conflict, and the ethics of abortion. 

They used a unique database of college syllabi collected by the “Open Syllabus Project” (OSP). The OSP has amassed millions of syllabi from around the world primarily by scraping them from university websites. They date as far back as 2008, though a majority are from the last ten years. Most of the data comes from universities in the United States, Britain, Canada, and Australia.

“Since all these issues sharply divide scholars, we wanted to know whether students were expected to read a wide or narrow range of perspectives on them. We wondered how well professors are introducing students to the moral and political controversies that divide intellectuals and roil our democracy. Not well, as it turns out.” 

In the summary of their findings, “Professors Need to Diversify What They Teach,” they report that they found a total lack of ideological diversity. “Across each issue we found that the academic norm is to shield students from some of our most important disagreements.”

Teaching of Israel and Palestine is, perhaps no surprise, totally lopsided, and we’ve seen the consequences since October 7, 2023. Staunchly anti-Zionist texts — those that question the moral legitimacy of the Israeli state — are commonly assigned. Rashid Khalidi, the retired professor of Modern Arab Studies at Columbia, is the most popular author on this topic in the database. A Palestinian American and adviser to the Palestine Liberation Organization delegation in the 1990s, Khalidi places the blame on Israel for failing to resolve the conflict and sees the country’s existence as a consequence of  settler-colonialism.

The problem is not the teaching of Khalidi itself, as some on the American right might insist. To the contrary, it is important for students to encounter voices like Khalidi’s. The problem is who he is usually taught with. Generally, Khalidi is taught with other critics of Israel, such as Charles D. Smith, Ilan Pappé, and James Gelvin.

Not only is Khalidi’s work rarely assigned alongside prominent critics, those critics seem to hardly get taught at all. They include Israel: A Concise History of a Nation Reborn by Daniel Gordis, a professor at Shalem College in Israel. Gordis’s book appears only 22 times in the syllabus database. Another example is the work of Efraim Karsh, a prominent historian. His widely cited classic, Fabricating Israeli History, appears just 24 times.

For most students, though, any exposure to the conflict begins and ends with Edward Said’s Orientalism, first published in 1978. Said is the intellectual godfather of so many of today’s scholars of the Middle East, thanks in no small part to this classic book. Said was a Palestinian-American academic, literary critic, and political activist from a prominent Christian family. Educated at Princeton and Harvard Universities, two of America’s most distinguished centres of higher learning, he taught at Columbia University, another Ivy League institution, until his death in 2003.

Said was no crude antisemite. His writings were aimed at academics and intellectuals and he has, in my opinion, done more damage to the Jewish people than anyone else after 1945. Said claimed to be the first scholar to “culturally and politically” identify “wholeheartedly with the Arabs.” But he was also a political activist for the Palestinian movement opposing the existence of Israel.

Said warned PLO leader Yasir Arafat that if the conflict remained local, they’d lose. Join “the universal political struggle against colonialism and imperialism,” with the Palestinians as freedom fighters paralleling “Vietnam, Algeria, Cuba, and black Africa,” he advised.

(In this he was not the first, though. Fayez Sayegh, a Syrian intellectual who departed for the United States and completed his Ph.D. at Georgetown University in 1949, preceded him. Also an academic, his 1965 monograph Zionist Colonialism in Palestine stands as the first intellectual articulation of Zionism as a settler colonial enterprise, arguing that the analytical frameworks applied to Vietnam and Algeria apply equally to Palestine. The treatise situated Zionism within European colonialism while presenting it as uniquely pernicious.)

Israel’s post–Six-Day War territorial expansion helped Said frame Israel as “an occupying power” in a 1979 manifesto titled The Question of Palestine. Alleging racial discrimination as the key motive was a means of transforming the “Zionist settler in Palestine” into an analogue of “white settlers in Africa.” That charge gained traction in a post-Sixties universe of civil rights, anti-imperialism, anti-colonialism, and Western self-abnegation. The work sought to turn the tables on the prevailing American understanding of Israel: It is not, in fact, an outpost of liberal democracy or refuge from antisemitism, but an instrument of white supremacy.

Orientalism popularized a framework through which today’s advocates on behalf of Palestinians understand their struggle against the state of Israel and the West generally. Said casts the Western world as the villains of history and peoples of the East as its noble victims.

The essence of the book, Said concluded, is the “ineradicable distinction between Western superiority and Oriental inferiority.” It falsely affirms “an absolute and systematic difference between the West, which is rational, developed, humane, superior, and the Orient, which is aberrant, undeveloped, inferior.”

So it was impossible to take Zionism seriously as one among the myriad nationalist movements that emerged in the nineteenth century, much less to see Israel itself as a land of refugees or the ancestral homeland of Jews. And, indeed, Said’s Orientalism singles out Israel for special rebuke, suggesting that the state could be justified only if one accepted the xenophobic ideology at the core of Western civilization. Israel’s defenders, particularly those who lament the lack of democracy in the Middle East and fault Arabs for their militancy, represent the “culmination of Orientalism.” 

Said is widely acknowledged as the godfather of the emerging field of postcolonial studies, and his views have profoundly shaped the study of the Middle East. Said also inspired – and in some cases directly mentored – a generation of anti-Zionist U.S. scholars whose dominance in the academic study of the area is unquestionable today.

The political left that emerged trained itself to read every conflict as the aftershock of colonialism. The ideological narrative of oppression and resistance allowed even the jihadist to become a post-colonial rebel.

It’s hard to overstate the academic influence of Orientalism.  The authors note that “As of this writing, it has been cited nearly 90 thousand times. It is also the 16th most assigned text in the OSP database, appearing in nearly 16 thousand courses. Orientalism is among the most popular books assigned in the United States, showing up in nearly 4,000 courses in the syllabus database. Said’s work appears in 6,732 courses in U.S. colleges and universities.

But although it was a major source of controversy, both then and now, it is rarely assigned with any of the critics Said sparred with, like Bernard Lewis, Ian Buruma, or Samuel Huntington. Instead, it’s most often taught with books by fellow luminaries of the postmodern left, such as Frantz Fanon and Judith Butler.

All these ideas are now embedded into diversity, equity, and inclusion identity politics, and “humanitarian” outrage over supposed Israeli “settler-colonialism,” “genocide,” and “apartheid.” 

The ground for the massive pro-Hamas college and university encampments, and attacks on Jewish students, was prepared decades ago. The long march of progressives through American institutions over the past decades has taken its toll on society.

Henry Srebrnik is a professor of political science at the University of Prince Edward Island.

Exchange Rate Factors: What Global Events Mean for Savvy Investors

When Russia invaded Ukraine in 2022, it created ripples in all financial markets, including currency markets. The Euro weakened while the dollar surged and emerging market currencies wobbled. Global factors can quickly affect financial markets and shake established trends. Apart from such rare events, currencies tend to change their price because of interest rates, inflation, and overall investor confidence. For investors managing money abroad, understanding these movements is critical to avoid losses and mitigate risks.

Below, we will break down how global political, economic, and cultural events influence exchange rates, with insights for savvy investors.

Economic factors

There are several key exchange rate factors with a consistent history of shaking financial markets. These factors include inflation, interest rates, trade balances, employment rates, and so on. Since economic factors are shaping markets almost daily, we start with those.

Inflation and interest rates

Inflation and interest rates are closely connected as one can easily affect the other. When inflation rises, central banks step in and raise interest rates to reduce inflation, and when inflation is lower, central banks can lower interest rates to make borrowing money cheaper. As a result, investors closely monitor these two metrics to anticipate changes in interest rates. Higher inflation makes currencies weaker, and whenever banks change the rates, the changes are immediately reflected in global currency rates. In the United States, the Federal Reserve is the central bank that sets interest rates in the country.

Trade balances and economic growth

A country that exports more than it imports has a stronger demand for its currency. More demand equals a stronger currency. However, the Japanese yen was always weaker against the dollar because the BOJ of Japan tends to have super low rates near 0 to support its exporters. Economic growth also increases demand for local currency as more investors try to invest in the country’s economy. Long-term investors often track this data to detect early signs of any changes in currency strength.

Political and geopolitical factors

Elections, sanctions, and overall political stability are also crucial factors. If the country gets under sanctions, its economy crumbles and its currency becomes inflationary, losing its value quickly. Elections are also crucial for a currency’s strength. Geopolitical events can have a serious impact on the currency as well. The most obvious example is the 2016 Brexit events that made GBP lose its value rapidly and violently. Global conflicts, such as wars, can seriously impact global financial assets, especially currency markets. When tensions are high, safe-haven currencies like USD and CHF (Swiss Franc) become very popular among investors as they seek a safe place to protect their capital.

Cultural and social factors

People like tourists, workers, and diaspora communities can shape currencies as well. Tourism usually drives seasonal demand, and countries that are popular destinations during certain seasons experience their currency appreciation as demand spikes. The perception matters as countries seen as safe and opportunity-rich tend to attract more investors, solidifying their currency strength.

Technology and innovation

Technology is seriously affecting everything, especially the financial sector. Digital payment systems, blockchain technology, and fintech startups have made it easy and swift to move money around. Cryptos and stablecoins enable investors to protect their capital using stablecoins during volatile times. The latest trend among banks is to work on CBDCs, which signals a new era where national currencies are blended with technology and blockchain. Despite this, currencies, even in their crypto form, will continue to be influenced by all major factors mentioned above, and knowing how these factors impact your currency is key to keeping your capital safe from risks.

Practical lessons for savvy investors

So, what do all these factors teach us about global currency rates and investing strategies? The key lies in proper preparations and anticipation. Monitoring macro trends, policy announcements, and major geopolitical and political developments is critical.

Diversify

The number one method which is used by professional investors is diversification. This simply means to spread your risks across a basket of assets. By not investing all your capital in one instrument, you can mitigate risks. If one asset experiences a loss, other ones will counter it with returns. Building a diversified portfolio is key to properly diversifying. For example: divide your capital to buy stocks, commodities, currencies, and cryptos so that if one fails to perform, others will counter it. This ensures a stable income without unnecessary losses in the long run.

Hedge

Forex options and ETFs are great hedging assets. Forex options let investors lock in an exchange rate for a future date, which is very useful if you expect volatility but want stability. Currency ETFs, on the other hand, track specific currencies or a basket of currencies and allow easy trading or protection without trading forex directly, but they are still risky.

Monitor the economic calendar

Economic calendar is a free online tool that aggregates important macroeconomic news data such as interest rate decisions, CPI, inflation, employment rates, central bank announcements and speeches, and other crucial information. By monitoring them, investors can always know when important news data will be released, and they can postpone their investment decisions to avoid volatile times and only invest after the main trend is determined.

The Canadian Dollar is on a slow decline. Should you save in euros or US dollars instead?

The Canadian dollar has been losing its value against the dollar this year. For Canadians, this raises a simple question: if your CAD is losing ground, is it better to move savings into euros or U.S. dollars, especially bonds, stocks, or a carry-trade strategy? Carry-trade strategy in this context means to borrow in CAD and invest it in the USA or the EU zone. This is a complex matter, and to understand where the CAD is, how attractive other currencies might be, we need to analyze these currencies more deeply. Below, we will walk you through the data, practical costs, and risks so you can reach a usable conclusion after reading this guide.

Quick snapshot – What the markets say right now

Recently, the Canadian dollar has hit multi-month lows due to weaker oil prices and a post-Fed (U.S. Federal Reserve) market reaction (which raised the rates, making the CAD weaker against the dollar). Canada’s central bank has cut its policy rate to 2.25%, while the Fed’s fund rate remains notably higher at about 3.75-4%. The ECB (European Central Bank) main interest rates are lower than the Fed’s and near the low-to-mid 2% range. While the Euro currency to USD rates remain mostly predictable, due to higher US bond yield rates, the EUR remains stronger, still. The U.S. 10-year Treasuries are around 4.1%, Canada’s 10-year near 3.2%, and Germany’s 10-year around 2.7%, meaning that today the USD-denominated bonds have the highest nominal yield among the three. As a result, the dollar seems much more attractive when it comes to bond yields and stocks.

Bonds – Which currency is the best for fixed income?

The short answer is: USD bonds. When it comes to nominal yield alone, US bonds beat almost all other competitors. U.S. government bond yields (10-year) are noticeably higher than Canadian and German/Eurozone bond yields right now. As a result, US bond buyers have more income potential than Canada and the EU. Euro-area core yields are lower, meaning they are paying less than the USA.

However, nominal yield does not mean it is guaranteed real return, and metrics like inflation, currency rates, and hedging costs can impact potential returns directly. If you buy USD bonds but the dollar falls against the CAD, currency losses will most likely wipe out the higher yield rate. If the Fed lowers its rates, it will make the dollar weaker against the CAD and EUR.

Another challenge is that, if you live and spend in Canada, you are using CAD, and when exchanging it for dollars, you get exposed to foreign currency rate risks, which must not be underestimated.

Stocks – Euro or dollar?

Both the EUR and USD have their advantages. USD has strong liquidity and strong long-term performance, while EUR equities offer valuation opportunities and recent relative strength.

Why USD?

The U.S. market remains the most liquid stock market with strong earnings for many tech and large companies. This makes USD stocks very attractive for long-term-oriented investors. S&P has been rising historically, and even after crashes, it often recovers its value relatively quickly.

Why EUR?

European indexes have performed well this year and in many cases cost less than their U.S. counterparts. While cheaper does not always mean better, these indexes still have some growth potential. Some major banks in the EU zone, together with industries, have recovered strongly with a recent focus on military manufacturing, making many EU stocks very attractive, together with local indexes.

However, here is a caveat: if you are using CAD daily and it loses its value against the euro, the returns from euro holdings might shrink, exposing you to greater currency risks.

Carry-trade analysis – Is it viable to borrow CAD and invest it in USD or EUR?

The basic promise of carry-trade is simple yet powerful: you borrow cheaper currency and invest it in currencies with higher yields. In our case, is it lucrative to borrow in CAD and invest in either EUR or USD? To answer this question, we need to look at numbers. BoC policy rate is 2.25%, Fed funds from 3.75%, U.S 10-yr is 4.1%, Canada 10-yr is 3.2%. If we deduct Canadian rates from the U.S. rates, we get around 1.8% positive before costs. So, in theory, it could be lucrative to invest CAD in USD assets using a carry trade. Since the ECB has around 2%, it is not profitable to use a carry-trade strategy for the euro.

The bottom line

While the CAD has been weakening lately, it is still not cheap enough to naively invest in USD or EUR. However, if you want a pure yield and can tolerate foreign exchange rate risks, USD bonds are more attractive today. When it comes to stocks, USD equities provide stable and liquid markets. If you want valuation potential and diversification, then euro equities have become more attractive this year. When it comes to carry-trade strategies, the USD remains more lucrative than the euro, but on paper, traders and investors should evaluate all the risks and costs before investing in any currency.

In the end, Canadians who have CAD for their daily costs should be careful when trying to get exposure to other markets. US bonds, US stocks, US carry-trade, and EU stocks remain attractive choices for experienced investors.
