By using a new imaging method, EMBL scientists observed DNA folding in real time, uncovering how loops stack to create rod-shaped chromosomes during cell division. Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a groundbreaking method called LoopTrace. By observing overlapping DNA loops forming in high resolution, they revealed that large loops form first, followed by nested smaller loops, all repelling each other into compact structures. This new insight not only reshapes our understanding of chromosome mechanics but could also help explain errors that lead to cancer and genetic disorders. The Mystery of Chromosome Division One of the most remarkable abilities of living cells is their capacity to divide, allowing organisms to grow, heal, and renew themselves. To do this, a cell must first make an exact copy of its DNA, its genome, and ensure each daughter cell receives a complete set. In humans, that means carefully packaging 46 chromosomes and distributing them equally. Before division, each chromosome transforms into a compact, X-shaped structure made of two identical, rod-like copies. But exactly how cells manage to reshape and organize their DNA for this process has remained a mystery. Now, for the first time, scientists at EMBL have directly visualized this process in high resolution using a new chromatin tracing technique. Their study reveals that during cell division, the long strands of DNA form a series of overlapping loops that push away from one another. This repulsion causes the loops to stack, ultimately giving each chromosome its characteristic rod-like shape. As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of DNA looping and stacking. Credit: Daniela Velasco Lozano/EMBL Looping DNA to Shape Chromosomes Scientists have long hypothesized the importance of DNA loops in building and maintaining chromosomal structure. First identified in the 1990s, condensins are large protein complexes that bind DNA during cell division and extrude it to create loops of varying sizes. Previous studies from EMBL have shed light on the structural mechanics of this process and their essential role in packing chromosomes into forms that can be easily moved between cells. In fact, mutations in condensin structure can result in severe chromosome segregation defects and lead to cell death, cancer formation, or rare developmental disorders called ‘condensinopathies’. The scientists built a computational model that allowed them to simulate the process of chromosome compaction based on a few fundamental assumptions. Credit: Beckwith et al., Cell. Solving the DNA Imaging Problem “However, observing how this looping process occurs on the cellular scale and contributes to chromosome structure is challenging,” said Andreas Brunner, postdoc in EMBL Heidelberg’s Ellenberg Group and a lead author of the new paper. “This is because methods for visualizing DNA with high resolution are usually chemically harsh and require high temperatures, which together disrupt the native structure of DNA.” Kai Beckwith, a former postdoc in the Ellenberg Group and currently an associate professor at the Norwegian University of Science and Technology (NTNU), set out to solve this problem. Beckwith and colleagues used a method to gently remove one strand of DNA in cells at various stages of cell division, keeping the chromosome structure intact. They could then use targeted sets of DNA-binding labels to observe the nanoscale organization of this uncovered DNA strand. This technique, called LoopTrace, helped the researchers directly observe DNA in dividing cells as it progressively formed loops and folds. “Andreas and I were now able to visualize the structure of chromosomes as they started to change shape,” said Beckwith. “This was crucial for understanding how the DNA was folded by the condensin complexes.” Nested Loops and DNA Compaction From their data, the scientists realized that during cell division, DNA forms loops in two stages. First, it forms stable large loops, which then subdivide into smaller, short-lived nested loops, increasing the compaction at each stage. Two types of condensin protein complexes enable this process. To understand how this looping eventually gives rise to rod-shaped chromosomes, the researchers built a computational model based on two simple assumptions. First, as observed, DNA forms overlapping loops – first large and then small – across its length with the help of Condensins. Second, these loops repel each other due to their structure and the chemistry of DNA. When the scientists fed these two assumptions into their model, they found that this was sufficient to give rise to a rod-shaped chromosome structure. Overlapping Loops Are Key “We realized that these condensin-driven loops are much larger than previously thought, and that it was very important that the large loops overlap to a significant extent,” said Beckwith. “Only these features allowed us to recapitulate the native structure of mitotic chromosomes in our model and understand how they can be segregated during cell division.” In the future, the researchers plan to study this process in more detail, especially to understand how additional factors, such as molecular regulators, affect this compaction process. In 2024, Jan Ellenberg and his team received funding of €3.1 million (~$3.4 million) as an ERC Advanced Grant, to study the folding principles of chromosomes during and following cell division. A Milestone for Chromosome Biology “Our newest paper published in the scientific journal Cell marks a milestone in our understanding of how the cell is able to pack chromosomes for their accurate segregation into daughter cells,” said Jan Ellenberg, Senior Scientist at EMBL Heidelberg. “It will be the basis to understand the molecular mechanism of rescaling the genome for faithful inheritance and thus rationally predict how errors in this process that underlie human disease could be prevented in the future.” In the meantime, a second study from the Ellenberg Team, led by Andreas Brunner and recently published in the Journal of Cell Biology, shows that the nested loop mechanism is fundamental to the biology of cells, and continues during the cell’s growth phase with another family of DNA loop forming protein complexes, called cohesins. Looping Mechanisms Across Cell Phases “We were surprised to find that the same core principle of sequential and hierarchical DNA loop formation is used to either tightly pack chromosomes during division into safely movable entities, or to unpack them afterward to read out the information they contain,” said Ellenberg. “In the end, small, but key mechanistic differences, such as the non-overlapping nature of cohesin-driven loops compared to the strongly overlapping condensin-driven loops might be sufficient to explain the vast differences that we see in the shape the genome takes in interphase and mitosis under the microscope.” References: Reference: “Nanoscale DNA tracing reveals the self-organization mechanism of mitotic chromosomes” by Kai Sandvold Beckwith, Andreas Brunner, Natalia Rosalia Morero, Ralf Jungmann and Jan Ellenberg, 24 March 2025, Cell.

A confrontation between stalk-eyed flies. Credit: Gerald Wilkinson Male stalk-eyed flies with longer eyestalks are more appealing to females and more intimidating to rival males. However, males with a genetic variant that results in shorter eyestalks tend to be more aggressive fighters. In stalk-eyed flies, males with longer eyestalks have an advantage in attracting females, as females tend to prefer them. These males also face less competition from other males for access to mates. However, some males carry a version of the X chromosome that results in shorter eyestalks. Scientists studying why this mutation persists, despite sexual selection favoring longer eyestalks, have found that males with shorter eyestalks may compensate by being more aggressive. “It’s the first time I’m aware of that there’s evidence of a link between a selfish gene and aggressive behavior,” said Dr Josephine Reinhardt of the State University of New York — Geneseo, corresponding author of the article in Frontiers in Ethology. “These driving X chromosomes are pretty interesting because they are an example of how parts of our genetic code aren’t necessarily working together, but have their own selfish interests. This is an extreme example, but simply carrying one of these selfish chromosomes impacts so many parts of these animals’ biology, even their behavior.” Swipe left? There are two different types of X chromosomes present in stalk-eyed flies. The X chromosome carrying the mutation for short eyestalks is a meiotic driver: it carries alleles which are over-represented in a male’s sperm, meaning it’s much more likely to be passed on. “The driving X chromosome has a huge natural advantage because it passes itself on more than the fair 50-50 ‘coin flip’ rule of genetics that most of us learned in high school biology,” explained Reinhardt. “Up to 100% of a male’s offspring end up inheriting the X and therefore are female. Because of this, we might assume the X will keep increasing in the population and even cause extinction. Since that hasn’t happened, we’re interested in understanding what other traits could counteract that advantage.” Duelling stalk-eyed flies. Credit: Gerald Wilkinson Male stalk-eyed flies defend access to mates by intimidating displays and fighting. To test whether flies carrying the driving X are more aggressive, the scientists used populations of flies carrying either type of X. Flies display more aggression against flies with similarly-sized eyestalks, so the researchers matched up competitors with similar eyestalks, then filmed their contests and analyzed their behavior. They found not only that fighting behaviors were more common when the two flies were closely matched in eyestalk size, but that these behaviors were more commonly seen in males with the driving X. Males that used more of these fighting behaviors were more likely to win contests. The scientists also observed that males with the driving X chromosome were more likely to win if they engaged in more fighting than displaying. “When fighters are mismatched, fights tend to end quickly, with the smaller male retreating,” Reinhardt said. “When a male with the driving X chromosome is fighting a male with similar-sized eyestalks, he is more aggressive. But because driving X males are on average smaller, it is likely still a disadvantage.” Flying high This could explain why the flies with short eyestalks were able to mate. Longer eyestalks signal a larger body size and more dangerous opponent, which is why flies with shorter eyestalks usually retreat from contests. If males with the driving X chromosome are more aggressive or don’t accurately assess the threat from other males, these males could choose to compete with males with longer eyestalks, bringing themselves into contact with the females initially attracted to their opponent. Although this extra aggression could be dangerous, it could also help the flies get mating opportunities they otherwise wouldn’t. However, it can’t fully counterbalance sexual selection. Modeling of the spread of the driving X suggests that this could explain why it hasn’t taken over: females still prefer males with longer eyestalks, keeping the variant’s frequency low. “I would say that this study is an initial finding,” cautioned Reinhardt. “A larger study might be done in which we specifically test for the increase in high-intensity behavior that we saw here in a larger sample. In addition, this is a laboratory study, so it is not totally clear how well it would apply to field behavior. Finally, females were not tested. If the driving X chromosome directly increases aggression that might impact females — whereas if it’s an indirect effect to do with the eyestalk size, it might not.” Reference: “Stalk-eyed flies carrying a driving X chromosome compensate by increasing fight intensity” by Kimberly A.

Analysis of data collected over 20 years suggests the decline is due to the construction of over 180 dams (dragonfly emerging from aquatic naiad state). Credit: Alexandre Castagna/Wikimedia Commons Analysis of data collected over 20 years suggests the decline is due to the construction of over 180 dams on the Paraná basin and its tributaries. Research conducted in Brazil for more than 20 years in the Paraná River basin shows a drastic fall in the number of aquatic insects in the region, which is considered well-preserved and distant from the negative impacts of agriculture, cattle breeding, and urbanization. The fieldwork was done by researchers affiliated with the State University of Maringá’s Center for Research in Limnology, Ichthyology and Aquaculture (NUPELIA-UEM). The data was systematized by Gustavo Romero, a professor at the University of Campinas’s Institute of Biology (IB-UNICAMP). An article on the study is published in a special issue on insect decline of Biology Letters, a journal of the UK’s Royal Society. “Our study analyzed data collected on a seasonal basis over a 20-year period. We detected a decline from thousands to tens of individuals per square meter,” Romero told Agência FAPESP. A commentary on the study by one member of the team is published in The Conversation.   The drastic decline in insect populations is a global phenomenon, Romero said, and studies have shown its correlation with human activities. A meta-analysis published in Science pointed to a fall in the number of terrestrial insects but claimed to have detected a rise in the abundance of aquatic insects. This article has since been contested by critics who argue that its authors based their conclusions on too small a sample, with only 7% of the insect datasets in their analysis coming from the tropics and the rest almost exclusively from the United States and Europe. Romero et al. studied a floodplain with an area of 40 square kilometers containing rivers, shallow lakes, channels and backwaters. The main cause of the decline in insect populations there was the construction of over 180 dams along the Paraná and its tributaries, which form one of South America’s largest freshwater systems, draining much of the central and southern portion of the continent. The study was supported by FAPESP via two grants awarded to Romero, and a postdoctoral fellowship awarded to Pablo Antiqueira, also a co-author of the published article. The study was conducted under the aegis of the FAPESP Research Program on Biodiversity Characterization, Conservation, Restoration and Sustainable Use (BIOTA-FAPESP) and the FAPESP Research Program on Global Climate Change (RPGCC).  “A sharp decline was observed not only in more susceptible species but in all aquatic insect orders and families that live in the area. These insects inhabit freshwater environments until they reach adulthood when they migrate to terrestrial environments. This includes dragonflies and water beetles, to mention only the most well-known,” Romero said. Because some insects transmit diseases (e.g. Aedes aegypti, which transmits dengue, zika, and yellow fever), many people wrongly think all insects are harmful to humans. “The insects that are being decimated in the Paraná River basin are extremely useful. They provide many ecosystem services, including pollination, biological control of crop pests and disease-transmitting insects, decomposition of organic matter, and nutrient cycling,” Romero said.  Consequence of dams Dams have impacts of three kinds, Romero continued. First, they make the water much clearer because particles in suspension settle on the reservoir bed before the flow enters the spillway. Deprived of their murky water camouflage, the insects that live downstream of the dam are even more vulnerable to being eaten by fish. Second, the exotic fish species introduced into dam reservoirs to promote sport fishing, such as the peacock bass (tucunaré) brought from the Amazon, are omnivores and eat insects as well as native fish. The third type of impact detected was a chemical imbalance of the nutrients in the water, changing the proportions of nitrogen and phosphorus. “The algae that proliferate in dam reservoirs fix nitrogen from the atmosphere and transfer it to the water. Part of the phosphorus is deposited on the reservoir bed. The water that flows through the dam spillway is poor in phosphorus and proportionally richer in nitrogen as a result. This changes its nutritional quality, affecting the animals that depend on a balanced quantity of these nutrients,” Romero explained. The Paraná River basin touches seven Brazilian states. Technically it is a sub-basin and, alongside the Paraguay and Uruguay River sub-basins, part of the Plata River system, one of South America’s three main basins. The other two are the Amazon and São Francisco River basins. Changes occurring in the ecosystems of the Paraná River sub-basin are therefore highly significant for the continent as a whole, and the decline in aquatic insect populations shows how human activities affect it even without taking into account the use of pesticides and sewage disposal into its rivers and lakes. The world has some 5.5 million insect species, 80% of which have yet to be described by science. This huge animal population, the most numerous on the planet, is rapidly being reduced by human activities, characterizing what some researchers are already calling the “insect apocalypse.” Reference: “Pervasive decline of subtropical aquatic insects over 20 years driven by water transparency, non-native fish and stoichiometric imbalance” by Gustavo Q.
