Chaim Saiman on Halakhah

Chaim Saiman Halakhah book coverThough typically translated as “Jewish law,” the term halakhah is not an easy match for what is usually thought of as law. In his panoramic book Halakhah: The Rabbinic Idea of Law, Chaim Saiman traces how generations of rabbis have used concepts forged in talmudic disputation to do the work that other societies assign not only to philosophy, political theory, theology, and ethics but also to art, drama, and literature. Guiding readers across two millennia of richly illuminating perspectives, this book shows how halakhah is not just “law,” but an entire way of thinking, being, and knowing.

What is halakhah and why did you decide to write a book about it?

Literally, halakhah means “the way” or “the path,” though it is typically translated as Jewish law.

I grew up in a home and community where I was expected not only to obey the law, but to study and master complex legal texts in Hebrew and Aramaic.

I was about eight years old when my father proceeded to pull out two massive tomes from the shelf and inform me that I had to learn with him before I could escape to the Nintendo console located in my friend’s basement. We began to study the section of Mishnah (the earliest code of Jewish law, from around the year 200 CE) detailing the responsibilities of different bailees—those who watch over the property belonging to someone else. This book is a grown-up attempt to answer why an eight-year-old should care about bailees and the ancient laws of lost cows.

Did you really start a book on Jewish law with Jesus?

Yes. I take Jesus and the Apostle Paul as some of the earliest in a long line of halakhah’s critics. Both lived before the tradition crystallized in the form of the Mishnah. Yet even at this early stage, Jesus pokes fun at the Mishnah’s forebears for obsessing over legal rules and formalities at the expense of true spiritual growth. Jesus would have most likely considered it a bad idea to initiate young children into religious life by analyzing the laws of bailments.  But whereas Jesus saw the law as a set of regulations and restrictions, the Talmudic rabbis understood it as a domain of exploration and study, a process they called Talmud Torah.

 What is Talmud Torah?

It is hard to translate, mainly because the idea does not exist in Western or American culture. Word-for-word it means the “study of Torah,” but its impact extends beyond what is usually thought of as “study.” Talmud Torah means that Torah is not studied merely for pre-professional reasons, and not (only) to know the rules relevant to living a Jewish life, but because it is a primary religious activity, an intimate spiritual act that brings the learner into God’s embrace.

The closest analogy in general culture is the idea once practiced at elite universities when the curriculum was focused on Greek, Latin, philosophy, ancient civilization, and classical literature. Unlike today, the goal was not to make students more attractive to employers, but to educate them into ennobled citizens who would fully realize their humanity. The rabbis had a similar idea, but rather than literature or philosophy, study was grounded in the divine word of the Torah, and especially the legal regulations set forth in the Mishnah and Talmud.

What does Talmud Torah have to do with law?

Though Talmud Torah arguably applies to any area of Jewish law and thought, longstanding tradition places special emphasis on the areas that correspond to contract, tort, property and business law—the very topics covered by secular legal systems.  According to the Talmudic rabbis, the subjects taught in law schools across the country become a spiritual practice when learned in the halakhic setting. Lawyers get many adjectives thrown their way, but godly is rarely one of them. The book aims to understand what it means to hold that legal study is a path to the divine, and what are the implications of this idea for a legal system.

Is halakhah the law of any country?

Not really. One of the unusual aspects of halakhah is that it first becomes visible in the Mishnah several generations after the independent Jewish state was dismantled by the Romans. Further, the most fertile periods of halakhic development took place when Jews did not govern any territory but lived as a minority under non-Jewish rule. This is the opposite from how legal systems typically develop.

From at least the Middle Ages through the nineteenth century, Jews tended to live in tight communities whose internal legal affairs were heavily influenced by rabbis and halakhah. But even here, close investigation shows that the civil laws that applied often deviated from Talmudic rules studied under the rubric of Talmud Torah. In the case of civil law there were effectively two systems of Jewish law. One used by tribunals when disputes arose in practice, and the other that lived mainly on the pages of the Talmud and realized though Torah study.  The relationship between these two forms of halakhah is a central theme of the book.

What about the state of Israel?

One of the ironies of modern Jewish life is that while Judaism historically defined itself through devotion to law, when the state of Israel was established there was little consensus about the role of halakhah in the state. Israel’s Socialist Zionist founders saw halakhah as a relic of the outmoded European Judaism that had to be overcome before a modern, Zionist, and self-determined Judaism could take hold. Most observant Jews by contrast, viewed secular Zionism as religiously invalid, if not dangerous. Since their primary concern was maintaining halakhah’s integrity in a secularizing world, they had little interest in adapting it for use in the modern state. Hence with the exception of marriage and divorce law, halakhah was not reflected in early Israeli law.

But the ground has shifted in the intervening years. Though Israeli law remains distinct from halakhah, there is a much wider constituency today that looks to define Israel as a Jewish state where concepts and norms inspired by halakhah find expression in state law. The book’s final chapter discusses the possibilities and pitfalls of infusing state law with halakhah.

Noah Wilson-Rich on The Best Bees Company

Author with beehive

Wilson-Rich on May 9, 2010, just six weeks after founding The Best Bees Company. Photo credit: Izzy Berdan

Pollinator decline is a grand challenge in the modern world. We are losing 40% of beehives annually nationwide, and more in places with tough winters, which are now at 50% or higher. Can you imagine if we lost half of our population each year? And if those we lost produced food for the rest of us? It’s untenable. I predict that at this rate, bees will be gone in 10 years. Furthermore, we will be without fruits and vegetables, causing global hunger, economic collapse, and a total moral crisis worldwide … if not for beekeepers, who replace those dead bees,

When I finished up my doctorate at Tufts University in honey bee immunology, I needed to find a laboratory, field sites, data points, and funding! It was 2009, in the deepest throws of the recession, so grant funding was more competitive for less resources, and the job market for academia was just as scarce. So I set up a laboratory of my own in the living room of my apartment in Boston, and started a Facebook page offering to install beehives at people’s home gardens and business rooftops in exchange for research funding. I’d volunteer my time to manage the beehives, they’d get all the honey, and I’d get the data.

And so our de factocitizen science journey began. We’d created a new way to engage the general public to own these little living data factories, pollinating gardens and farms, allowing everyone to participate in research.

When I told my apartment landlord in Boston that I’d set up a bee research lab in my living room, I was admittedly nervous. I must have caught him on a good day. He replied not with an eviction notice, but with a big smile and said, “Let’s put those bees in the back alley!” I was shocked. To all of our delight, that little data factory produced more honey that first year than any other beehive I’d ever worked. Over 100 lbs.! We were filling up pickle jars with the stuff! Since honey never goes bad, some of the tenants are still sharing it with their loved ones and the greater community.

The Bee coverThat beehive and this citizen science approach, shifted my research question forever. It moved me away from why bees were dying, as so many researchers ask, and toward what is it about this beehive – this urban beehive – that’s allowing these bees to live and thrive?

With that, The Best Bees Company was born! As we grew, more people and companies got our research-based beekeeping services throughout urban, suburban, and rural towns alike. Meanwhile, the more data we got, the more accurate our maps became. Trends began to emerge for precisely where bees were thriving best.

Nine years later, The Best Bees Company and I oversee 1000 beehives, in 10 greater metro areas, with 65 beekeepers on our team in this little company that we made up. We’ve brought in 25 million pollinators nationwide, enhancing the properties of citizen scientists. That’s 10 million data points, this year alone, a sum of nearly 20 million data points since the first pickle jar beehive. For my team, that scale meant more accurate maps, which we now share with NASA and Google Earth. And now I can report what’s saving bees to you.

You, too, can be part a citizen scientist – If you have a balcony in your apartment, a backyard at your home, you can participate in stabilizing our food system!

Bird Fact Friday – the Andean and Austral Negrito

Adapted from page 189 of Birds of Chile:

The Austral Negrito is frequently found in central or southern Chile. These birds are common summer residents from eastern Aysén, and south to Tierra del Fuego. They are fairly common from northern Chiloé to southern Atacama, mainly near the coast. Additionally, they are local in Andes. During the winter, these birds withdraw north, when they are common in Central Chile, and rare north of Arica. They prefer open areas, from sandy beaches to grassy plains, lakeshores, and riverbanks. They’re also rather quiet, with soft, high chips at times, and in display flight males give high, accelerating chips and a high slurred tssiu that carries well. Sexes are similar while immature, while the adult male is darker.

The Andean Negrito inhabits the North Andes, and is fairly common but somewhat local to Coquimbo. They frequently live in bogs, adjacent to open ground. Their calls are quiet, slightly frog like peeks. Both sexes have whitish wing patches, but female are paler. Their habits are very similar to the Austral Negrito.

Amazing Arachnids: Vinegaroons

Adapted from pages 69-74 of Amazing Arachnids:

Armed with heavy, lobsterlike claws at the front end of their bodies and shooting almost pure acetic acid out of their rear ends, vinegaroons seem to have stepped straight out of a science fiction novel. Despite their fantastic abilities, vinegaroons are perhaps the most poorly understood of the large arachnids. This may be the result of their nocturnal habits, dark nonfluorescent coloration, and the fact that they live most of their lives underground. However, the story of these enigmatic creatures is well worth the cost, albeit paid for in sleepless nights. Their story rivals and even surpasses the creations of fiction.

The common name “vinegaroon” is well chosen. The defensive spray of the vinegaroon Mastigoproctus giganteus of the southwestern United States consists primarily of acetic acid (up to 84 percent), water (10 percent), and caprylic acid (5 percent). Acetic acid is, of course, the component that gives vinegar its characteristic odor. Hydrophilic “water-loving” acetic acid in pure form simply beads up on the lipid-containing cuticle of most arthropods. But with the addition of the lipophilic “lipid-loving” caprylic acid, the spray spreads easily and penetrates into the cuticle. The caprylic acid derives its surfactant properties from a chain of 8 carbon atoms in the molecule, as compared with only 2 carbons contained in acetic acid. The acetic acid spray is produced in a pair of pygidial glands in the abdomen of the vinegaroon. Contraction of muscles in the outer layer surrounding the gland discharges the mixture as a spray from a knoblike structure called the pygidium at the base of the “tail” (called the flagellum). By bending the abdomen and rotating the knob, the vinegaroon can direct the spray with considerable accuracy, even if the target is almost directly in front of it.

As added protection, vinegaroons can defend themselves by spraying almost pure acetic acid from the pygidium, located at the base of the flagellum. By rotating the pygidium, the vinegaroon can aim the spray in almost any direction, even almost immediately in front of it. The flagellum assists the vinegaroon in accurately aiming the spray. Photo by Bruce D. Taubert.

Vinegaroons may spray repeatedly (as many as 19 times) before depleting their reserve of defensive chemicals. It takes about a day for them to recharge their reservoir. The spray has proven to serve as a deterrent to the most formidable arthropod foes such as ants. It also repels vertebrate predators such as the fierce little predaceous grasshopper mice. In contact with human skin, it may cause a burning sensation, and of course the eyes of a potential vertebrate predator such as a bird or a grasshopper mouse would be highly vulnerable to the effects of the acid.

The acetic acid is used purely as a defense weapon—not for capturing prey. A hunting vinegaroon employs tools similar to those used by scorpions for  detecting prey. A combination of sensilla (to pick up substrate vibrations) and trichobothria (to detect airborne vibrations) on the uropygid’s legs allow it to narrow down the general location of its quarry. The tiny hairs on the flagellum might also assist in this task. At the same time, the antenniform legs are extended forward, tapping the surface as the uropygid seeks out prey. Chemosensory hairs on the antenniform legs provide chemical clues as to the identity of any objects it encounters. As soon as the vinegaroon has positively identified a potential prey animal, it charges forward, grabbing with its heavy, clawlike palps. If it misses with the first try, it excitedly feels around with the antenniform legs, searching until it has once again located its quarry.

There are 4 free living instar stages before maturation, and since the young uropygid may not molt following a poor year, it may take from 5 to 7 years to reach maturity. Vinegaroons do not molt again once they are mature, and so their normal lifespan in the wild is probably in the range of 6 to 9 years. Eventually, this magnificent predator slows down due to old age, as joints stiffen and lost appendages cannot be regenerated. Perhaps even in the wild, it may actually die of old age, still a formidable predator to the end.

 

Amazing Arachnids
By Jillian Cowles

The American Southwest is home to an extraordinary diversity of arachnids, from spitting spiders that squirt silk over their prey to scorpions that court one another with kissing and dancing. Amazing Arachnids presents these enigmatic creatures as you have never seen them before. Featuring a wealth of color photos of more than 300 different kinds of arachnids from eleven taxonomic orders–both rare and common species—this stunningly illustrated book reveals the secret lives of arachnids in breathtaking detail, including never-before-seen images of their underground behavior.

Amazing Arachnids covers all aspects of arachnid biology, such as anatomy, sociality, mimicry, camouflage, and venoms. You will meet bolas spiders that lure their victims with fake moth pheromones, fishing spiders that woo their mates with silk-wrapped gifts, chivalrous cellar spiders, tiny mites, and massive tarantulas, as well as many others. Along the way, you will learn why arachnids are living fossils in some respects and nimble opportunists in others, and how natural selection has perfected their sensory structures, defense mechanisms, reproductive strategies, and hunting methods.

Life on Mars: Imagining Martians

If you had the chance to travel to Mars, would you take it?

Astronomer David A. Weintraub thinks it won’t be long before we are faced with this question not as a hypothetical, but as a real option. Based on the pace of research and the growing private interest in space exploration, humans might be considering trips to Mars before the next century.

In his new book Life on Mars: What to Know Before We Go, Weintraub argues that would-be colonizers of the red planet should first learn whether life already exists on Mars. Just as colonization of various parts of Earth has historically decimated human, animal, and plant populations, so, argues Weintraub, will human colonization of Mars dramatically affect and likely destroy any life that might already exist on Mars. Before we visit, we need to know what – and whom – we might be visiting.

While scientists have yet to determine whether life exists on the red planet, they agree that if Martians do exist, they probably aren’t little green men. So where does our popular idea of Martians come from? Artists and writers have been imagining and depicting Martian life in a variety of ways since long before space travel was a reality. Check out these descriptions of imagined Martian life from over one hundred years ago.

Cover of The Martian, by George du Maurier

In George du Maurier’s 1897 gothic science fiction story The Martian, Martians are described as furry amphibians who are highly skilled in metalworking and sculpting:

“Man in Mars is, it appears, a very different being from what he is here. He is amphibious, and descends from no monkey, but from a small animal that seems to be something between our seal and our sea-lion….

“His five senses are extraordinarily acute, even the sense of touch in his webbed fingers and toes….

“These exemplary Martians wear no clothes but the exquisite fur with which nature has endowed them, and which constitutes a part of their immense beauty….

“They feed exclusively on edible moss and roots and submarine seaweed, which they know how to grow and prepare and preserve. Except for heavy-winged bat-like birds, and big fish, which they have domesticated and use for their own purposes in an incredible manner (incarnating a portion of themselves and their consciousness at will in their bodies), they have cleared Mars of all useless and harmful and mutually destructive forms of animal life. A sorry fauna, the Martian—even at its best—and a flora beneath contempt, compared to ours.”

“How the Earth Men Learned the Martian Language,” from Edison’s Conquest of Mars by Garrett P. Serviss

In Garrett Serviss’s Edison’s Conquest of Mars (1898), on the other hand, Martians are huge creatures, two to three times as tall as a human:

“It is impossible for me to describe the appearance of this creature in terms that would be readily understood. Was he like a man? Yes and no. He possessed many human characteristics, but they were exaggerated and monstrous in scale and in detail. His head was of enormous size, and his huge projecting eyes gleamed with a strange fire of intelligence. His face was like a caricature, but not one to make the beholder laugh. Drawing himself up, he towered to a height of at least fifteen feet.”

Edwin Lester Arnold, in Lieut. Gullivar Jones: His Vacation, published in 1905, describes Martians instead as “graceful and slow,” with an “odor of friendly, slothful happiness about them”:

“They were the prettiest, daintiest folk ever eyes looked upon, well-formed and like to us as could be in the main, but slender and willowy, so dainty and light, both the men and the women, so pretty of cheek and hair, so mild of aspect, I felt, as I strode amongst them, I could have plucked them like flowers and bound them up in bunches with my belt. And yet somehow I liked them from the first minute; such a happy, careless, light-hearted race, again I say, never was seen before.” 

“The old man sat and talked with me for hours,” from A Princess of Mars by Edgar Rice Burroughs

And in Edgar Rice Burroughs’ A Princess of Mars, published in 1917, Martians are finally depicted as the little green men of the popular imagination:

“Five or six had already hatched and the grotesque caricatures which sat blinking in the sunlight were enough to cause me to doubt my sanity. They seemed mostly head, with little scrawny bodies, long necks and six legs, or, as I afterward learned, two legs and two arms, with an intermediary pair of limbs which could be used at will either as arms or legs. Their eyes were set at the extreme sides of their heads a trifle above the center and protruded in such a manner that they could be directed either forward or back and also independently of each other, thus permitting this queer animal to look in any direction, or in two directions at once, without the necessity of turning the head.

“The ears, which were slightly above the eyes and closer together, were small, cup-shaped antennae, protruding not more than an inch on these young specimens. Their noses were but longitudinal slits in the center of their faces, midway between their mouths and ears.

“There was no hair on their bodies, which were of a very light yellowish-green color. In the adults, as I was to learn quite soon, this color deepens to an olive green and is darker in the male than in the female. Further, the heads of the adults are not so out of proportion to their bodies as in the case of the young.”

Read PUP’s 2017 National Jewish Book Award winners!

We’re proud to announce that four Princeton University Press titles were winners and/or finalists for the 2017 National Jewish Book Awards. These four books examine the lives of Jewish women in medieval Islamic society, a famous case of anti-Semitism in eighteenth-century Germany, the origins of Jews as a people, and the meanings of the Hebrew language.

Winner of the 2017 National Jewish Book Award in Women’s Studies (Barbara Dobkin Award)

Finalist for the 2017 National Jewish Book Award in Scholarship (Nahum Sarna Memorial Award)

Much of what we know about life in the medieval Islamic Middle East comes from texts written to impart religious ideals or to chronicle the movements of great men. How did women participate in the societies these texts describe? What about non-Muslims, whose own religious traditions descended partly from pre-Islamic late antiquity?

Coming of Age in Medieval Egypt approaches these questions through Jewish women’s adolescence in Fatimid and Ayyubid Egypt and Syria (c. 969–1250). Using hundreds of everyday papers preserved in the Cairo Geniza, Eve Krakowski follows the lives of girls from different social classes—rich and poor, secluded and physically mobile—as they prepared to marry and become social adults.

Krakowski also suggests a new approach to religious identity in premodern Islamic societies—and to the history of rabbinic Judaism. Through the lens of women’s coming-of-age, she demonstrates that even Jews who faithfully observed rabbinic law did not always understand the world in rabbinic terms. By tracing the fault lines between rabbinic legal practice and its practitioners’ lives, Krakowski explains how rabbinic Judaism adapted to the Islamic Middle Ages. Read the introduction.

Winner of the 2017 National Jewish Book Award in History (Gerrard and Ella Berman Memorial Award)

Joseph Süss Oppenheimer—”Jew Süss”—is one of the most iconic figures in the history of anti-Semitism. In 1733, Oppenheimer became the “court Jew” of Carl Alexander, the duke of the small German state of Württemberg. When Carl Alexander died unexpectedly, the Württemberg authorities arrested Oppenheimer, put him on trial, and condemned him to death for unspecified “misdeeds.”

The Many Deaths of Jew Süss is a compelling new account of Oppenheimer’s notorious trial. Drawing on a wealth of rare archival evidence, Yair Mintzker investigates conflicting versions of Oppenheimer’s life and death as told by four contemporaries: the leading inquisitor in the criminal investigation, the most important eyewitness to Oppenheimer’s final days, a fellow court Jew who was permitted to visit Oppenheimer on the eve of his execution, and one of Oppenheimer’s earliest biographers.

The Many Deaths of Jew Süss is a masterfully innovative work of history, and an illuminating parable about Jewish life in the fraught transition to modernity. Check out this Q&A with Mintzker, or read the introduction.

Winner of the 2017 National Jewish Book Award in Education and Jewish Identity (In Memory of Dorothy Kripke)

In The Origin of the Jews, Steven Weitzman takes a learned and lively look at what we know—or think we know—about where the Jews came from, when they arose, and how they came to be.

This is the first book to trace the history of the different approaches that have been applied to the question, including genealogy, linguistics, archaeology, psychology, sociology, and genetics. Weitzman shows how this quest has been fraught since its inception with religious and political agendas, how anti-Semitism cast its long shadow over generations of learning, and how recent claims about Jewish origins have been difficult to disentangle from the Israeli-Palestinian conflict. He does not offer neatly packaged conclusions but invites readers on an intellectual adventure, shedding new light on the assumptions and biases of those seeking answers—and the challenges that have made finding answers so elusive. Read the introduction!

The Story of Hebrew takes readers from the opening verses of Genesis—which seemingly describe the creation of Hebrew itself—to the reincarnation of Hebrew as the everyday language of the Jewish state. Lewis Glinert explains the uses and meanings of Hebrew in ancient Israel and its role as a medium for wisdom and prayer. He describes the early rabbis’ preservation of Hebrew following the Babylonian exile, the challenges posed by Arabic, and the prolific use of Hebrew in Diaspora art, spirituality, and science. Glinert looks at the conflicted relationship Christians had with Hebrew from the Renaissance to the Counter-Reformation, the language’s fatal rivalry with Yiddish, the dreamers and schemers that made modern Hebrew a reality, and how a lost pre-Holocaust textual ethos is being renewed today by Orthodox Jews.

The Story of Hebrew explores the extraordinary hold that Hebrew has had on Jews and Christians, who have invested it with a symbolic power far beyond that of any other language in history. Check out this Q&A with Glinert, or read the book’s introduction.

Bird Fact Friday – The Short-eared Owl

Adapted from pages 184-185 of Wildlife of the Arctic:

While breeding, male Short-eared owls have buff and white facial discs, with a black bill and yellow eyes. Their underparts are pale buff, paler still on the belly, the whole streaked with dark brown, the streaking heavier on the breast and throat. Their upperparts are tawny-buff, heavily streaked dark brown. Breeding females are similar, but deeper buff and, in general, are more heavily marked.  

In studies of the owl’s diet mammals constituted around 95% of the biomass, with rodents and shrews providing the bulk of that percentage, though the owls also take stoats and weasels. Birds, amphibians, reptiles and insects provide the remaining 5%. Arctic breeding Short-eareds are invariably ground nesters, Short-eareds being one of few owls that makes a ‘proper’ nest. In it the female lays 2-13 eggs, the species reacting in a similar fashion to Snowy Owls in lemming years.

This photo illustrates how the Short-eared Owl (Asio flammeus) can turn its head through 180° to look directly over its back.

Short-eared Owl breeds on Iceland, in northern Fennoscandia and across Russia to Kamchatka, though rarely to the north coast. Breeds in Alaska, the Yukon and North-West Territories, around Hudson Bay, in Labrador and on southern Baffin Island. At all times the actual distribution of the owls is dependent on prey density, but northern owls do move south to north-west Europe, central Asia and continental United States.

Plants That Kill: Apocynaceae

Adapted from page 52 of Plants That Kill:

The dogbane family is one of the larger families of flowering plants, and is today considered to contain more than 5,000 species in 366 recognized genera, including those that have, at times, been placed in their own family, Asclepiadaceae. The almost globally distributed Apocynaceae (only northern regions lack native species) has adapted to almost all environments and contains a large diversity of plant forms. 

Species grow as herbs, climbers and lianas, succulents or trees. The flowers are often showy or conspicuous in form or smell, and many species have evolved special structures for pollen dispersal, such as pollinia, coherent masses of pollen grains that are transferred to the next plant by sticking to insect pollinators. These structures are especially elaborate in milkweeds (Asclepias spp.), waxflowers (Hoya spp.) and their relatives, constituting a feature that allows easy placement of these plants within the family (although deciding on the actual genus and species can be quite difficult).

Elephant vine (Strophanthus amboensis) is found from Zaire to Namibia and contains cardioactive steroids. The petals are fused to form a cup at the base and there are five spreading, elongated lobes.

The large number of species and wide geographical distribution of the dogbane family makes it easy to understand why so many plants are used by humans. The showy, waxy flowers of frangipani (Plumeria spp.) have found a place as a constituent in Polynesian lei garlands, the fibres from dogbane (Apocynum cannabinum) have been used to make cloth and string, some species are used in religious rituals, and some genera, such as Landolphia, were briefly important as sources of rubber in the late nineteenth and early twentieth centuries. Several plants in the family have been used as arrow poisons or in traditional medicinal systems, and the Madagascar periwinkle (Catharanthus roseus) is the source of an important cancer drug. 

It seems that most plants in the dogbane family are toxic to some degree, but the reason for this differs between groups of species. Some groups produce cardioactive steroids as the toxic principle, while others produce monoterpene indole alkaloids. Accordingly, the family presents several toxidromes, the combined picture of symptoms in poisonings, with some presenting as acute heart failure with arrhythmias and others giving signs of detrimental effects on the nervous system – for example, seizures, paralysis and hallucinations. As members of the dogbane family are widely distributed and many produce fatal intoxications, the use of these plants in suicides and poisonings is not uncommon in certain regions of the world.

This richly illustrated book provides an in-depth natural history of the most poisonous plants on earth, covering everything from the lethal effects of hemlock and deadly nightshade to the uses of such plants in medicine, ritual, and chemical warfare.

Featuring hundreds of color photos and diagrams throughout, Plants That Kill explains how certain plants evolved toxicity to deter herbivores and other threats and sheds light on their physiology and the biochemistry involved in the production of their toxins. It discusses the interactions of poisonous plants with other organisms–particularly humans—and explores the various ways plant toxins can target the normal functioning of bodily systems in mammals, from the effects of wolfsbane on the heart to toxins that cause a skin reaction when combined with the sun’s rays. This intriguing book also looks at plants that can harm you only if your exposure to them is prolonged, the ethnobotany of poisons throughout human history, and much more.

A must for experts and armchair botanists alike, Plants That Kill is the essential illustrated compendium to these deadly and intriguing plants.

Bird Fact Friday – the Bald Eagle

Adapted from pages 94-95 of Wildlife of the Arctic

The Bald Eagle is a magnificent bird, the Nearctic equivalent of the White-tailed Eagle. Adults have a white head (the origin of the name) and white tail, but are otherwise dark brown, with a pattern of scalloping from pale feather tips. Sexes are similar. Juvenile eagles do not acquire the adult coloring until they are 3-5 years old. In early young immatures there is a significant amount of white in the plumage which aids distinguishing the birds from adult Golden Eagles. Northern birds are larger than their cousins of the souther US states, the two being considered sub-species.

This bird is piscivorous but an opportunistic feeder, taking both terrestrial and aquatic mammals (e.g. hares and muskrats) as well as birds (primarily waterfowl and gulls). They also feed on carrion and are not infrequent visitors to garbage dumps in Alaska. They hunt both by flying slowly over probable prey sites and from perches, and will pirate food from other Bald Eagles, as well as from Osprey and herons, both of which are, in general, better at fishing but cannot defend themselves against the eagles. They also makes piratical attacks on Peregrines and even on Sea Otters and Coyotes.

Bald eagles nest primarily in trees, and often re-uses nests which may actually be refurbished prior to the birds migrating as well as when they return to the breeding site. One nest known to have been used continuously over several decades grew to be almost 3m in diameter and over 3m high and weighed an estimated 2t: the tree then blew down in a storm. In areas where trees are absent, they will nest on cliffs or even on the ground provided the site is elevated to give the incubating bird good visibility. 1-3, but usually 2, eggs are laid. Asynchronous hatching means first chick hatched usually outcompetes later hatchlings which may die of starvation.

The Bald Eagle is the emblem of the United States, which made it even sadder when numbers declined sharply as a result of subsidised shooting and the widespread use of organochlorines in the continental US. In Alaska the use of pesticides was minimal, but a bounty on eagles set in 1917 – the result of lobbying by fishermen and fox trappers – was not lifted until 1953. Although the bounty led to ill-advised slaughter, the state remained a stronghold of the species and continues to do so. Once hunting and DDT were banned the population recovered quickly: in Alaska the population increased by about 70% between the late 1960s and the late 1990s. Alaska and the Canadian province of British Columbia are the strongholds of the species with the population now probably close to the carrying capacity of the environment.

Bald Eagles breed in central and southern Alaska, including the Aleutians, and across North America, but rarely north of the timberline. In winter the birds move to the continental United States, though birds in southern Alaska are resident.

Plants That Kill: Aconite alkaloids

From hemlock and deadly nightshade to poppies and tobacco, poisonous plants have long been used in medicine, rituals, and even warfare. For the next few months, Princeton Nature will be taking a closer look at the evolution, survival strategies, physiology, and biochemistry of the most toxic plants on Earth. Pulling from Elizabeth A. Dauncey & Sonny Larsson’s new book, Plants That Kill, we hope to provide you with just a sample of the deadly and intriguing plants that can be found in this gorgeously illustrated book.

Adapted from page 48-49 of Plants That Kill:

Aconite alkaloids are mostly restricted to a small number of genera in the buttercup family, particularly the aconites (Aconitum spp.) and their close relatives the larkspurs (Delphinium spp.). The presence of the compounds seems to give these plants a strong evolutionary advantage, as the group constitutes about a third of all species within the family. Aconites and larkspurs produce these highly toxic compounds from a substance called geranylgeranyl diphosphate, which is an essential part of the chlorophyll needed for photosynthesis. They can be grouped into three different ‘flavors’, called veatchine, atisine and aconitine alkaloids. The compounds in the last of these groups are the most toxic, which is thought to be due to their ability to pass through fat-containing barriers such as cell membranes and also the skin. This explains why gardeners and florists who, with bare hands, handle the cut stems or crushed material of aconite and larkspur plants in large amounts or for extended periods of time may experience mild symptoms of tingling or numbness.

There are around 250 species of aconite (Aconitum spp.) found in the wild in the northern hemisphere, but they are also widely grown in temperate gardens and sold as cut flowers.                              Photo credit: Alex Polo, Shutterstock

Species of aconite are used to treat joint pain in traditional Chinese herbal medicine in the form of bath additives, rubs and ointments. Their alkaloids can be absorbed through the skin, where they act as local anaesthetics. They may also be taken orally to treat asthma, gastroenteritis and various tumours, or as a supportive and revitalizing tonic. How is this possible, when these plants are very poisonous and small amounts can cause dangerous, or even lethal, effects on the heart and respiratory muscles? 

Before use, the raw material must be subjected to pao zhi (a detoxifying measure), which might include heating and/or soaking with the intention of ensuring maximal therapeutic efficacy with minimal adverse effects. During such processes, the toxic alkaloids are transformed into less harmful compounds, explaining why aconite use has persisted in spite of its high risk of poisoning. However, even though pao zhi is usually performed, a number of patients who take traditional Chinese aconite medicines are hospitalized each year due to poisoning.

Introducing Volume 15 of The Collected Papers of Albert Einstein

From fraudulent science to hope for European reunification, the newest volume of The Collected Papers of Albert Einstein conveys the breakneck speed of Einstein’s personal and professional life. Volume 15, covering June 1925 to May 1927, is out now!

THE COLLECTED PAPERS OF ALBERT EINSTEIN
Volume 15: The Berlin Years
Writings & Correspondence, June 1925-May 1927, Documentary Edition

Edited by Diana Kormos Buchwald, József Illy, A. J. Kox, Dennis Lehmkuhl, Ze’ev Rosenkranz & Jennifer Nollar James

Princeton University Press, the Einstein Papers Project at the California Institute of Technology, and the Albert Einstein Archives at the Hebrew University of Jerusalem, are pleased to announce the latest volume in the authoritative COLLECTED PAPERS OF ALBERT EINSTEIN. This volume covers one of the most thrilling two-year periods in twentieth-century physics, as matrix mechanics—developed chiefly by W. Heisenberg, M. Born, and P. Jordan—and wave mechanics—developed by E. Schrödinger—supplanted earlier quantum theory. The almost one hundred writings, a third of which have never before been published, and the more than thirteen hundred letters demonstrate Einstein’s immense productivity at a tumultuous time.

Within this volume, Einstein grasps the conceptual peculiarities involved in the new quantum mechanics; falls victim to scientific fraud while in collaboration with E. Rupp; and continues his participation in the League of Nations’ International Committee on Intellectual Cooperation.

ENGLISH TRANSLATION SUPPLEMENT

Every document in The Collected Papers of Albert Einstein appears in the language in which it was written, and this supplementary paperback volume presents the English translations of select portions of non-English materials in Volume 15. This translation does not include notes or annotation of the documentary volume and is not intended for use without the original language documentary edition which provides the extensive editorial commentary necessary for a full historical and scientific understanding of the documents.

THE COLLECTED PAPERS OF ALBERT EINSTEIN

Diana Kormos Buchwald, General Editor

THE COLLECTED PAPERS OF ALBERT EINSTEIN is one of the most ambitious publishing ventures ever undertaken in the documentation of the history of science.  Selected from among more than 40,000 documents contained in the personal collection of Albert Einstein (1879-1955), and 20,000 Einstein and Einstein-related documents discovered by the editors since the beginning of the Einstein Papers Project, The Collected Papers provides the first complete picture of a massive written legacy that ranges from Einstein’s first work on the special and general theories of relativity and the origins of quantum theory, to expressions of his profound concern with international cooperation and reconciliation, civil liberties, education, Zionism, pacifism, and disarmament.  The series will contain over 14,000 documents as full text and will fill close to thirty volumes.  Sponsored by the Hebrew University of Jerusalem and Princeton University Press, the project is located at and supported by the California Institute of Technology and has made available a monumental collection of primary material. It will continue to do so over the life of the project. The Albert Einstein Archives is located at the Hebrew University of Jerusalem. The open access digital edition of the first 14 volumes of the Collected Papers is available online at einsteinpapers.press.princeton.edu.

ABOUT THE SERIES: Fifteen volumes covering Einstein’s life and work up to his forty-eighth birthday have so far been published. They present more than 500 writings and 7,000 letters written by and to Einstein. Every document in The Collected Papers appears in the language in which it was written, while the introduction, headnotes, footnotes, and other scholarly apparatus are in English.  Upon release of each volume, Princeton University Press also publishes an English translation of previously untranslated non-English documents.

ABOUT THE EDITORS: At the California Institute of Technology, Diana Kormos Buchwald is professor of history; A. J. Kox is senior editor and visiting associate in history; József Illy and Ze’ev Rosenkranz are editors and senior researchers in history; Dennis Lehmkuhl is research assistant professor and scientific editor; and Jennifer Nollar James is assistant editor.
