What a carve-up: when French and British ruled the world
James Gillray's 'plumb-pudding' caricature is "probably the most famous political cartoon of all time."

William Pitt and Napoleon Bonaparte, carving up the world between them.
- The fight for world dominance always seems to involve a contest between two superpowers.
- Back in 1805, it was the British versus the French, and this cartoon pokes fun at both.
- Pitt and Napoleon are carving out the big slices of the world-pudding – an image endlessly copied since.
The Great Game

The Great Game remains the same: how to gobble up most of the world, or at least more of it than your opponent can swallow. It's just the players that change. In our times, the two top dogs are the United States and China. During the Cold War, it was the U.S. versus the Soviet Union. And in 1805, the year this cartoon was published, the main contenders were the British and the French.
Across the top, the title reads: The Plumb-pudding in danger: - or – State Epicures taking un Petit Souper. The pudding is of course the earth itself, steaming on a plate between the two 'state epicures'. Seated opposite each other and armed with an oversized knife and fork each, they are carving into the pudding, eager to indulge their insatiable geopolitical appetite.
On the left, we have William Pitt the Younger, Prime Minister of the United Kingdom. On the right: Napoleon Bonaparte. No longer content to be called First Consul of France, Napoleon had only recently crowned himself Emperor. Both are wearing their 'work clothes', i.e. military uniforms. Pitt is dressed in the red coat typical for the British army of the time. Napoleon is wearing the blue coat of the Imperial French Army.
And it's not just by these primary colours that the artist underlines their opposition. Pitt's hat is a tricorn, Napoleon's a bicorn (festooned with a cockerel-like plume in the French tricolor). And, perhaps most obviously, Pitt is tall and spindly, his French counterpart–true to the caricature already current at the time–short and stocky.
What they're doing to that poor pudding between them is also rich in symbolism. Clearly visible at the center of the globe are the British Isles – obviously, the most important part of the globe, at least to the cartoon's British audience.
Invade or reconcile

Both Pitt and Napoleon are using a carving knife and fork to cut slices off the pudding. Pitt's fork is a trident, reminiscent of British sea power; Napoleon's knife resembles a sword, perhaps referring to French supremacy on land. Pitt is slicing off a big chunk of the ocean, while Napoleon is helping himself to continental Europe.
Napoleon's fork is sticking into a part of Europe labeled 'Hanover' – no doubt a reminder to the British audience that the French now occupied the ancestral home of the Hanoverian dynasty sitting on the British throne. Perhaps also to please his audience, the cartoonist shows Napoleon's piece as significantly smaller than Pitt's.
Pitt and Napoleon each have a golden plate in front of them to put their slice of the world on. Pitt's is emblazoned with the British Royal Coat of Arms, Napoleon's with the Imperial Crown. Pitt's chair shows a lion carrying the Cross of St George, the emblem of England. Napoleon's chair has an imperial eagle holding on to a Phrygian cap, the bonnet that came to symbolize the French revolution.
So, what's going on? The publication date, February 1805, marks a curious lull in the Napoleonic Wars (1803-15). A few months earlier, Napoleon had amassed a potential force for invading Britain in Boulogne-sur-Mer. But now he was making overtures for reconciliation with his enemy across the English Channel.
Spheres of influence

As the cartoon suggested, peace with Britain would entail both parties establishing a sphere of influence: for Britain, the seas and its colonies (the map shows the West Indies but not Britain's recently lost North American possessions); for France, the European mainland.
As it turned out, both the invasion and the reconciliation fell through. Later that same year, Nelson would defeat a Franco-Spanish fleet at Trafalgar, establishing Britain's maritime dominance without having had to resort to political compromise with France.
For a while at least, Napoleon would continue his victorious streak on the mainland – meaning the cartoon was a prediction that came true. But in the end, Napoleon would be defeated – not once, but twice; at Waterloo in 1815 for the final time (see also #1050).
Sold in hand-colored prints, this is likely the most famous work by James Gillray (1756-1815), one of two contenders for the title of Britain's most influential caricaturist – the other being William Hogarth. Martin Rowson, cartoonist for the Guardian, calls it "probably the most famous political cartoon of all time."
Interestingly, it's a thematic elaboration of one of Gillray's earlier cartoons. In 1789, he depicted 'Jack Tar' and Napoleon sitting astride the globe, with the British sailor punching the Frenchman a bloody nose. At that time, Napoleon must have been an unknown in Britain, because he is depicted as a scrawny, full-figured person, not the "little corporal" of later times.
Perhaps this cartoon is less popular than the later one because the world is explained not as a delicious 'plumb-pudding' but as a less appetising 'dunghill'.

Weird science shows unseemly way beetles escape after being eaten
Certain water beetles can escape from frogs after being consumed.
R. attenuata escaping from a black-spotted pond frog.
- A Japanese scientist shows that some beetles can wiggle out of frog's butts after being eaten whole.
- The research suggests the beetle can get out in as little as 7 minutes.
- Most of the beetles swallowed in the experiment survived with no complications after being excreted.
In what is perhaps one of the weirdest experiments ever that comes from the category of "why did anyone need to know this?" scientists have proven that the Regimbartia attenuata beetle can climb out of a frog's butt after being eaten.
The research was carried out by Kobe University ecologist Shinji Sugiura. His team found that the majority of beetles swallowed by black-spotted pond frogs (Pelophylax nigromaculatus) used in their experiment managed to escape about 6 hours after and were perfectly fine.
"Here, I report active escape of the aquatic beetle R. attenuata from the vents of five frog species via the digestive tract," writes Sugiura in a new paper, adding "although adult beetles were easily eaten by frogs, 90 percent of swallowed beetles were excreted within six hours after being eaten and, surprisingly, were still alive."
One bug even got out in as little as 7 minutes.
Sugiura also tried putting wax on the legs of some of the beetles, preventing them from moving. These ones were not able to make it out alive, taking from 38 to 150 hours to be digested.
Naturally, as anyone would upon encountering such a story, you're wondering where's the video. Thankfully, the scientists recorded the proceedings:
The Regimbartia attenuata beetle can be found in the tropics, especially as pests in fish hatcheries. It's not the only kind of creature that can survive being swallowed. A recent study showed that snake eels are able to burrow out of the stomachs of fish using their sharp tails, only to become stuck, die, and be mummified in the gut cavity. Scientists are calling the beetle's ability the first documented "active prey escape." Usually, such travelers through the digestive tract have particular adaptations that make it possible for them to withstand extreme pH and lack of oxygen. The researchers think the beetle's trick is in inducing the frog to open a so-called "vent" controlled by the sphincter muscle.
"Individuals were always excreted head first from the frog vent, suggesting that R. attenuata stimulates the hind gut, urging the frog to defecate," explains Sugiura.

We're creating pigs with human immune systems to study illness
Are "humanized" pigs the future of medical research?
The U.S. Food and Drug Administration requires all new medicines to be tested in animals before use in people. Pigs make better medical research subjects than mice, because they are closer to humans in size, physiology and genetic makeup.
In recent years, our team at Iowa State University has found a way to make pigs an even closer stand-in for humans. We have successfully transferred components of the human immune system into pigs that lack a functional immune system. This breakthrough has the potential to accelerate medical research in many areas, including virus and vaccine research, as well as cancer and stem cell therapeutics.
Existing biomedical models
Severe Combined Immunodeficiency, or SCID, is a genetic condition that causes impaired development of the immune system. People can develop SCID, as dramatized in the 1976 movie “The Boy in the Plastic Bubble." Other animals can develop SCID, too, including mice.
Researchers in the 1980s recognized that SCID mice could be implanted with human immune cells for further study. Such mice are called “humanized" mice and have been optimized over the past 30 years to study many questions relevant to human health.
Mice are the most commonly used animal in biomedical research, but results from mice often do not translate well to human responses, thanks to differences in metabolism, size and divergent cell functions compared with people.
Nonhuman primates are also used for medical research and are certainly closer stand-ins for humans. But using them for this purpose raises numerous ethical considerations. With these concerns in mind, the National Institutes of Health retired most of its chimpanzees from biomedical research in 2013.
Alternative animal models are in demand.
Swine are a viable option for medical research because of their similarities to humans. And with their widespread commercial use, pigs are met with fewer ethical dilemmas than primates. Upwards of 100 million hogs are slaughtered each year for food in the U.S.
Humanizing pigs
In 2012, groups at Iowa State University and Kansas State University, including Jack Dekkers, an expert in animal breeding and genetics, and Raymond Rowland, a specialist in animal diseases, serendipitously discovered a naturally occurring genetic mutation in pigs that caused SCID. We wondered if we could develop these pigs to create a new biomedical model.
Our group has worked for nearly a decade developing and optimizing SCID pigs for applications in biomedical research. In 2018, we achieved a twofold milestone when working with animal physiologist Jason Ross and his lab. Together we developed a more immunocompromised pig than the original SCID pig – and successfully humanized it, by transferring cultured human immune stem cells into the livers of developing piglets.
During early fetal development, immune cells develop within the liver, providing an opportunity to introduce human cells. We inject human immune stem cells into fetal pig livers using ultrasound imaging as a guide. As the pig fetus develops, the injected human immune stem cells begin to differentiate – or change into other kinds of cells – and spread through the pig's body. Once SCID piglets are born, we can detect human immune cells in their blood, liver, spleen and thymus gland. This humanization is what makes them so valuable for testing new medical treatments.
We have found that human ovarian tumors survive and grow in SCID pigs, giving us an opportunity to study ovarian cancer in a new way. Similarly, because human skin survives on SCID pigs, scientists may be able to develop new treatments for skin burns. Other research possibilities are numerous.

Pigs in a bubble
Since our pigs lack essential components of their immune system, they are extremely susceptible to infection and require special housing to help reduce exposure to pathogens.
SCID pigs are raised in bubble biocontainment facilities. Positive pressure rooms, which maintain a higher air pressure than the surrounding environment to keep pathogens out, are coupled with highly filtered air and water. All personnel are required to wear full personal protective equipment. We typically have anywhere from two to 15 SCID pigs and breeding animals at a given time. (Our breeding animals do not have SCID, but they are genetic carriers of the mutation, so their offspring may have SCID.)
As with any animal research, ethical considerations are always front and center. All our protocols are approved by Iowa State University's Institutional Animal Care and Use Committee and are in accordance with The National Institutes of Health's Guide for the Care and Use of Laboratory Animals.
Every day, twice a day, our pigs are checked by expert caretakers who monitor their health status and provide engagement. We have veterinarians on call. If any pigs fall ill, and drug or antibiotic intervention does not improve their condition, the animals are humanely euthanized.
Our goal is to continue optimizing our humanized SCID pigs so they can be more readily available for stem cell therapy testing, as well as research in other areas, including cancer. We hope the development of the SCID pig model will pave the way for advancements in therapeutic testing, with the long-term goal of improving human patient outcomes.

A new warning to sign to predict volcanic eruptions?
Satellite imagery can help better predict volcanic eruptions by monitoring changes in surface temperature near volcanoes.

- A recent study used data collected by NASA satellites to conduct a statistical analysis of surface temperatures near volcanoes that erupted from 2002 to 2019.
- The results showed that surface temperatures near volcanoes gradually increased in the months and years prior to eruptions.
- The method was able to detect potential eruptions that were not anticipated by other volcano monitoring methods, such as eruptions in Japan in 2014 and Chile in 2015.
How can modern technology help warn us of impending volcanic eruptions?
One promising answer may lie in satellite imagery. In a recent study published in Nature Geoscience, researchers used infrared data collected by NASA satellites to study the conditions near volcanoes in the months and years before they erupted.
The results revealed a pattern: Prior to eruptions, an unusually large amount of heat had been escaping through soil near volcanoes. This diffusion of subterranean heat — which is a byproduct of "large-scale thermal unrest" — could potentially represent a warning sign of future eruptions.
Conceptual model of large-scale thermal unrestCredit: Girona et al.
For the study, the researchers conducted a statistical analysis of changes in surface temperature near volcanoes, using data collected over 16.5 years by NASA's Terra and Aqua satellites. The results showed that eruptions tended to occur around the time when surface temperatures near the volcanoes peaked.
Eruptions were preceded by "subtle but significant long-term (years), large-scale (tens of square kilometres) increases in their radiant heat flux (up to ~1 °C in median radiant temperature)," the researchers wrote. After eruptions, surface temperatures reliably decreased, though the cool-down period took longer for bigger eruptions.
"Volcanoes can experience thermal unrest for several years before eruption," the researchers wrote. "This thermal unrest is dominated by a large-scale phenomenon operating over extensive areas of volcanic edifices, can be an early indicator of volcanic reactivation, can increase prior to different types of eruption and can be tracked through a statistical analysis of little-processed (that is, radiance or radiant temperature) satellite-based remote sensing data with high temporal resolution."

Although using satellites to monitor thermal unrest wouldn't enable scientists to make hyper-specific eruption predictions (like predicting the exact day), it could significantly improve prediction efforts. Seismologists and volcanologists currently use a range of techniques to forecast eruptions, including monitoring for gas emissions, ground deformation, and changes to nearby water channels, to name a few.
Still, none of these techniques have proven completely reliable, both because of the science and the practical barriers (e.g. funding) standing in the way of large-scale monitoring. In 2014, for example, Japan's Mount Ontake suddenly erupted, killing 63 people. It was the nation's deadliest eruption in nearly a century.
In the study, the researchers found that surface temperatures near Mount Ontake had been increasing in the two years prior to the eruption. To date, no other monitoring method has detected "well-defined" warning signs for the 2014 disaster, the researchers noted.
The researchers hope satellite-based infrared monitoring techniques, combined with existing methods, can improve prediction efforts for volcanic eruptions. Volcanic eruptions have killed about 2,000 people since 2000.
"Our findings can open new horizons to better constrain magma–hydrothermal interaction processes, especially when integrated with other datasets, allowing us to explore the thermal budget of volcanoes and anticipate eruptions that are very difficult to forecast through other geophysical/geochemical methods."
