Ancient DNA Reveals Phoenicians' Surprising Ancestry
An ancient Middle Eastern civilization that developed an early alphabet spread its culture far and wide—but not its DNA, finds a 23 April Nature study of hundreds of ancient human genomes.
Phoenician civilization emerged more than 3,000 years ago, centred around what is now Lebanon, before expanding across the Mediterranean Sea. Middle Eastern Phoenician city-states eventually fell to other groups, but the culture thrived farther west—most notably in Carthage, in what is now Tunisia, until its destruction in 146 BC.
Phoenician city-states shared languages—recorded with an alphabet that was a precursor to Greek and Latin letters—religious practices and maritime trading economies. Many researchers have presumed that their inhabitants also shared ancestries connected to the culture's Middle Eastern origins.

To study this history, population geneticist Harald Ringbauer at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and his colleagues analysed the DNA from the remains of around 200 people from Phoenician archaeological sites in the Middle East, Europe and North Africa.
Ancestry puzzle
To Ringbauer's surprise, people from Mediterranean outposts of Phoenician culture—also known as Punic people—shared no ancestry with ancient Middle Easterners, even those from sites linked to Phoenicians and their forebears the Canaanites.
But neither did Punic people's genomes always resemble those of people from other local populations, such as those in Sardinia and Ibiza. Instead, Punic people shared an ancestry profile resembling those of ancient inhabitants of Greece and Sicily. Over time, North African ancestry entered the mix—reflecting the rise of Carthage after 500 BC.
This unique mixture of ancestries is probably the result of a regular influx of diverse people connected by a 'Mediterranean highway' maintained by trade between Phoenician outposts, says Ringbauer. The study identified related individuals found at distant archaeological sites, including a pair of possible second cousins, one from North Africa and one from Sicily.
After the fall of Phoenician city-states in the Middle East, people with ancestry from this region might have been cut off from the Mediterranean highway, says Ringbauer.
The absence of Middle Eastern ancestry in Punic people doesn't surprise Pierre Zalloua, a geneticist at Khalifa University in Abu Dhabi, United Arab Emirates. 'The Phoenicians were a culture of integration and assimilation,' he says. 'They settled where they sailed.'
Ringbauer would like to know why diverse Mediterranean people adopted Phoenician culture, instead of sticking to their existing practices. 'How can there be such a disconnect?' he wonders. 'Does this mean Phoenician culture was like a franchise that others could adopt? That's one for the archaeologists.'

It's official: Your diet is making you depressed, according to science
Skipping dessert really can leave you down in the dumps. No one who's been on a diet has ever said, 'I love calorie restriction,' but a new study has found a not-so-surprising link between low-cal eating and depression. And some people have it worse than others. 3 Researchers found that men and those whose BMI classified them as overweight were particularly susceptible to diet-linked depression. Studio Romantic – The dietary habits and depressive symptoms of 28,000 US adults were analyzed for the study, published in BMJ Nutrition Prevention & Health. Of these adults, 29% had a healthy weight, 33% were deemed overweight, and 38% were considered obese. The dietary patterns were divided into four categories: calorie-restrictive, nutrient-restrictive (AKA low in fat), sugar, salt, or carbs, established dietary pattern, or not on a diet at all. The majority of participants, 87%, did not follow any specific diet, 8% followed a calorie-restrictive diet, 3% opted for nutrient restriction, and 2% followed an established dietary pattern. Using questionnaires from the US National Health and Nutrition Examination Survey, researchers found that 8% of participants reported depressive symptoms. Those on calorie or nutrient-restrictive diets exhibited higher scores of emotional and physical distress than their cohorts who were not on a specific diet, suggesting that unsupervised restrictive diets may negatively affect mental health. Researchers found that men and those whose BMI classified them as overweight were particularly susceptible to diet-linked depression. 3 Besides affecting your quality of life and relationships, depression can raise the risk of heart disease, diabetes, stroke, dementia, Alzheimer's disease, anxiety disorders, and substance abuse. bravissimos – 'The findings suggest caution with overly restrictive or unbalanced diets, particularly for people already experiencing weight-related stress or challenges,' said lead study author Dr. Venkat Bhat, psychiatrist, clinician-researcher, and director of the Interventional Psychiatry Program at St. Michael's Hospital and University of Toronto. Researchers found that the quality of diet had a direct bearing on depression risk. Those whose diet was rife with ultra-processed foods (UPFs) were more likely to report higher levels of depression. Recent research revealed that 60% of Americans' daily caloric intake comes from ultra-processed foods. UPFs often contain high levels of sodium, refined sugars, cholesterol-spiking fats and other lab-based ingredients. A 2023 study from the Harvard T.H. Chan School of Public Health found that people who consume nine or more servings of UPFs a day have a 50% higher risk of developing depression than those who eat four or fewer daily servings. 3 Previous studies have established that a Mediterranean diet rich in fruit, veggies, nuts, fish, and plants can slash depression risk by a third. Eightshot Images – In contrast, this latest study revealed that those who followed a Mediterranean diet exhibited lower rates of depression. Previous studies have established that a Mediterranean diet rich in fruit, veggies, nuts, fish, and plants can slash depression risk by a third. In a 2023 Gallup poll, 29% of US adults reported having been diagnosed with depression at some point in their lifetime, while 17.8% of Americans said they have depression or are being treated for it. Besides affecting your quality of life and relationships, depression can raise the risk of heart disease, diabetes, stroke, dementia, Alzheimer's disease, anxiety disorders and substance abuse. Given the results of this study, Bhat suggests dieters abstain from strict caloric restriction and instead opt for,' balanced, sustainable dietary changes that meet nutritional needs.' Researchers note that their findings only reveal associations, not definitive data. Further, due to the survey format, there's no way to verify that participants truly adhere to caloric restriction. Still, Bhat and his team are hopeful that future studies will continue to examine the relationship between calorie restriction and mental health.

First evidence of ‘living towers' made of worms discovered in nature
Nature seems to offer an escape from the hustle and bustle of city life, but the world at your feet may tell another story. Even in the shade of a fruit tree, you could be surrounded by tiny skyscrapers — not made of steel or concrete, but of microscopic worms wriggling and writhing into the shape of long, vertical towers. Even though these miniature architects, called nematodes, are found all over Earth's surface, scientists in Germany recently witnessed their impressive building techniques in nature for the first time. After months of closely inspecting rotten pears and apples in local orchards, researchers from the Max Planck Institute of Animal Behavior and the University of Konstanz were able to spot hundreds of the 1-millimeter-long (0.04-inch) worms climbing onto one another, amassing structures up to 10 times their individual size. Related video Rare video shows 12 sharks co-feed socially To learn more about the mysterious physics of the soft, slimy towers, the study team brought samples of nematodes called Caenorhabditis elegans into a lab and analyzed them. There, the scientists noticed the worms could assemble in a matter of hours, with some reaching out from the twisting mass as exploratory 'arms' sensing the environment and building accordingly. But why the worms formed the structures wasn't immediately clear. The team's findings, published Thursday in the journal Current Biology, show that even the smallest animals can prompt big questions about the evolutionary purpose of social behaviors. 'What we got was more than just some worms standing on top of each other,' said senior study author Serena Ding, a Max Planck research group leader of genes and behavior. 'It's a coordinated superorganism, acting and moving as a whole.' To find out what was motivating the nematodes' building behavior, the study team tested the worms' reactions to being poked, prodded and even visited by a fly — all while stacked in a tower formation. 'We saw that they are very reactive to the presence of a stimulus,' said the study's first author, Daniela Perez, who is a postdoctoral researcher at the Max Planck Institute of Animal Behavior. 'They sense it, and then the tower goes towards this stimulus, attaching itself to our metal pick or a fly buzzing around.' This coordinated reaction suggests the hungry nematodes may be joining together to easily hitch a ride on larger animals such as insects that transport them to (not so) greener pastures with more rotten fruit to feast on, Perez said. 'If you think about it, an animal that is 1 millimeter long cannot just crawl all the way to the next fruit 2 meters (6.6 feet) away. It could easily die on the way there, or be eaten by a predator,' Perez explained. Nematodes are capable of hitchhiking solo too, she added, but arriving to a new area in a group may allow them to continue reproducing. The structures themselves may also serve as a mode of transport, as evidenced by how some worms formed bridges across gaps within the petri dishes to get from one surface to another, Perez noted. 'This discovery is really exciting,' said Orit Peleg, an associate professor of computer science who studies living systems at the University of Colorado Boulder's BioFrontiers Institute. 'It's both establishing the ecological function of creating a tower, and it really opens up the door to do more controlled experimentation to try to understand the perceptual world of these organisms, and how they communicate within a large group.' Peleg was not involved in the study. As the next step, Perez said her team would like to learn whether the formation of these structures is a cooperative or competitive behavior. In other words, are the towering nematodes behaving socially to help each other out, or are their towers more akin to a Black Friday sale stampede? Studying the behaviors of other self-assembling creatures could offer clues to the social norms of nematodes and help answer this question, Ding said. Ants, which assemble to form buoyant rafts to survive floodwaters, are among the few creatures known to team up like nematodes, said David Hu, a professor of mechanical engineering and biology at Georgia Tech. Hu was not involved in the study. 'Ants are incredibly sacrificial for one another, and they do not generally fight within the colony,' Hu said. 'That's because of their genetics. They all come from the same queen, so they are like siblings.' Like ants, nematodes didn't appear to display any obvious role differentiation or hierarchy within the tower structures, Perez said. Each worm from the base to the top of the structure was equally mobile and strong, indicating no competition was at play. However, the lab-cultivated worms were basically clones of one another, so it's not clear whether role differentiation occurs more often in nature, where nematode populations could have more genetic differences, she noted. Additionally, socially cooperative creatures tend to use some form of communication, Peleg said. In the case of ants, it may be their pheromone trails, while honeybees rely on their ritual dance routines and slime molds use their pulsing chemical signals. With nematodes, however, it's still not clear how they might communicate — or if they are communicating at all, Ding said. 'The next steps for (the team) are really just choosing the next questions to ask.' Notably, there has been a lot of interest in studying cooperative animal behaviors among the robotics community, Hu said. It's possible that one day, he added, information about the complex sociality of creatures like nematodes could be used to inform how technology, such as computer servers or drone systems, communicates.

This Genetic ‘Trick' Helped the Black Death Linger for Centuries
Yersinia pestis—the bacterium that causes the bubonic plague—experienced a genetic tweak that allowed rodents to live longer after they were infected, according to a new study. This alteration may have prolonged two significant plague pandemics, including the deadliest event in human history: the Black Death. Researchers at the Institut Pasteur in France and McMaster University in Canada studied hundreds of ancient Y. pestis DNA samples to investigate a gene called 'pla.' Their study, published May 29 in the journal Science, identified a decrease in repetitions of the pla gene in the Y. pestis genome during the later stages of both the first and second major plague pandemics. The researchers believe these pla depletions ultimately allowed these pandemics to last longer. The first plague pandemic, known as the Plague of Justinian, struck the Mediterranean basin during the sixth century and caused tens of millions of deaths over the course of two centuries. The second emerged when the Black Death broke out in 1347, killing an estimated 30% to 50% of Europe's population in just six years. But this was just the beginning. Like the first pandemic, this plague continued to reemerge for centuries, lasting more than 500 years. This newly discovered evolution of the pla gene offers more insight into how these plagues persisted for so long. The pla gene appears many times in the Y. pestis' genome and plays a crucial role in its virulence by allowing it to infect the lymph nodes before traveling to the rest of the body, according to an Institut Pasteur statement. This causes rapid septicemia—or blood poisoning—and quickly kills the victim. Therefore, a lack of this gene in Y. pestis strains from the first and second major pandemics likely made the bacterium less virulent, the researchers suggest. To test that hypothesis, they infected mice with three preserved strains of Y. pestis from the third major pandemic that also had fewer repetitions of pla. 'These three samples enabled us to analyze the biological impact of these pla gene deletions,' said co-author Javier Pizarro-Cerdá, director of the Yersinia Research Unit at the Institut Pasteur, according to the statement. Through their mouse model, Pizarro-Cerdá and his colleagues found that the pla depletion resulted in a 20% decrease in victim mortality. What's more, it allowed infected rodents to live significantly longer. Based on these findings, the researchers concluded that rats infected with pla-depleted Y. pestis strains may have been more effective disease vectors, as they had more time to spread the plague far and wide before they died. Rodents—particularly rats—played a critical role in spreading the bubonic plague to humans. People most commonly contract this disease via infected flea bites, and fleas typically contract it when they feed on infected rodents. Thus, an increase in the lifespans of sickened rodents would have provided greater opportunity for fleas to bite them, become infected, and then bite humans. 'Ours is one of the first research studies to directly examine changes in an ancient pathogen, one we still see today, in an attempt to understand what drives the virulence, persistence, and eventual extinction of pandemics,' said co-lead author Hendrik Poinar, director of the McMaster Ancient DNA Centre and holder of the Michael G. DeGroote Chair in Genetic Anthropology, according to the statement. Today, the bubonic plague is considered a rare disease, though a small number of cases still emerge in western North America, Africa, Asia, and South America, according to the Cleveland Clinic. While this research provides valuable insight into the evolutionary history of Y. pestis and the world-altering pandemics it caused, it can also serve as a model for better understanding how deadly diseases emerge and spread, according to the researchers.
