Credit: Benoit Gallet and Martin Oeggerli, Micronaut A groundbreaking study reveals a protein shell in diatoms that enhances their CO2 fixation capabilities, offering new avenues for bioengineering to combat climate change by optimizing photosynthesis. Tiny ocean diatoms are highly efficient at capturing carbon dioxide (CO2) from the environment, accounting for up to 20 percent of the Earth’s CO2 fixation. Researchers at the University of Basel in Switzerland have now discovered a protein shell within these algae that is essential for their ability to fix CO2 so effectively. This significant finding could inspire new bioengineering strategies to help reduce atmospheric CO2 levels. Diatom Discovery and Carbon Capture Diatoms, though invisible to the naked eye, are among the most productive algae in the ocean and play a crucial role in the global carbon cycle. Through photosynthesis, they absorb large amounts of CO2 from the environment and convert it into nutrients that sustain much of ocean life. Despite their significance, how diatoms perform this process so efficiently has remained a mystery. Now, researchers led by Prof. Ben Engel at the University of Basel’s Biozentrum, along with teams from the University of York, UK, and Kwansei-Gakuin University in Japan, have uncovered a protein shell crucial to diatoms’ CO2 fixation. Using advanced imaging techniques like cryo-electron tomography (cryo-ET), they mapped the molecular structure of the PyShell protein sheath and revealed its function. These findings were recently published in two papers in the journal Cell. Cryo-electron tomography reveals the molecular architecture of the diatom pyrenoid, showing how Rubisco is surrounded by the PyShell, increasing the efficiency of carbon dioxide fixation. Credit: Gröger et al. / Manon Demulder, Biozentrum, Universität Basel PyShell: A Key to Efficient Photosynthesis In plants and algae, photosynthesis takes place in chloroplasts. Inside these chloroplasts, energy from sunlight is harvested by thylakoid membranes and then used to help the enzyme Rubisco fix CO2. However, algae have an advantage: they pack all their Rubisco into small compartments called pyrenoids, where CO2 can be captured more efficiently. “We have now discovered that diatom pyrenoids are encased in a lattice-like protein shell,” says Dr. Manon Demulder, author on both studies. “The PyShell not only gives the pyrenoid its shape, but it helps create a high CO2 concentration in this compartment. This enables Rubisco to efficiently fix CO2 from the ocean and convert it into nutrients.” When the researchers removed the PyShell from the algae, their ability to fix CO2 was significantly impaired. Photosynthesis and cell growth were reduced. “This showed us how important the PyShell is for efficient carbon capture – a process that is crucial for ocean life and the global climate,” says Manon Demulder. Potential Climate Solutions Through Bioengineering The discovery of the PyShell could also open promising avenues for biotechnological research aimed at combatting climate change – one of the most pressing challenges of our time. “First of all, we humans must reduce our CO2 emissions to slow the pace of climate change. This requires immediate action,” says Ben Engel. “The CO2 that we emit now will remain in our atmosphere for thousands of years. We hope that discoveries such as the PyShell can help inspire new biotechnology applications that improve photosynthesis and capture more CO2 from the atmosphere. These are long-term goals, but given the irreversibility of CO2 emissions, it is important that we perform basic research now to create more opportunities for future carbon-capture innovations.” Reference: “Diatom pyrenoids are encased in a protein shell that enables efficient CO2 fixation” by Ginga Shimakawa, Manon Demulder, Serena Flori, Akihiro Kawamoto, Yoshinori Tsuji, Hermanus Nawaly, Atsuko Tanaka, Rei Tohda, Tadayoshi Ota, Hiroaki Matsui, Natsumi Morishima, Ryosuke Okubo, Wojciech Wietrzynski, Lorenz Lamm, Ricardo D.

Previous studies found that mothers of twins are more fertile. However, new research shows they are not. Is it true that women who have twins are more fertile? While prior research concluded they are, a rigorous analysis of more than 100,000 births from pre-industrial Europe by an international team of scientists shows they are not. The results of the study are now published in the scientific journal Nature Communications. In humans, twinning usually occurs in around 1–3% of all births. Twinning is found in all populations despite being associated with a much higher risk than single pregnancies of natal and postnatal health issues for both the mother and her children. Given these risks, it seems that natural selection has prevented twinning from becoming more common during evolution. But why then has evolution by natural selection not prevented twinning altogether? Previous science had mixed up cause and effect. “If a mother gives birth more often, it is more likely that one of these births is to twins – just like you are more likely to win if you buy more lottery tickets.” One popular hypothesis has been that survival risks brought by twinning are partially hidden from natural selection because twinning comes with higher fertility. The general idea is that women who are more fertile than average are also more likely to release more than one egg when they ovulate – making twinning a marker of high fertility. Many studies have analyzed demographic data and obtained results consistent with this view. However, this new study shows that the former analyses have been flawed. “Previous studies are problematic because they cannot tell us whether mothers with twins give birth more often because they are especially fertile, or because giving birth more often increases the chance that one of these births is to twins,” explains principal investigator Alexandre Courtiol from the Leibniz Institute for Zoo and Wildlife Research in Germany. Twinning Does Not Indicate Higher Fertility The new results show that twinners (someone who gives birth to twins) are not unusually fertile. Previous science had mixed up cause and effect. “If a mother gives birth more often, it is more likely that one of these births is to twins – just like you are more likely to win if you buy more lottery tickets, or to be in a car accident if you drive a lot,” adds first author Ian Rickard from Durham University, UK. When the “lottery ticket effect” is taken into account, the authors found that mothers more likely to have twins actually gave birth less often – a result that contradicts previous findings. To re-examine the relationship between twinning and fertility, the international team of 14 scientists combined large datasets of birth outcomes from several parts of pre-industrial Europe (today’s Finland, Sweden, Norway, Germany, and Switzerland). “All these data originate from old parish records that have been meticulously digitized and transcribed,” explains co-author Virpi Lummaa from the University of Turku, Finland. “To avoid the statistical trap that plagued former studies, we also had to deploy efficient and carefully calibrated statistical procedures,” adds co-author François Rousset from the Institut des Sciences de l’Evolution in Montpellier, France. Figuring out what shapes the relationship between twinning and fertility is not only a question of academic interest but also a matter of public health. Indeed, biomedical studies looking for ways to improve female fertility have compared mothers with and without twins. However, co-author Erik Postma from the University of Exeter in the UK points out that, “such study designs ignore the multitude of factors influencing how often a woman gives birth, which will mask any genuine differences in physiology between mothers with and without twins.” In short, comparing groups of mothers with twins to groups of mothers without may hide the effects of twinning and fertility genes where they exist, or create the illusion of these if they do not exist. Why Natural Selection Has Not Eliminated Twinning “There is still much we do not understand about twinning, but our study suggests that twinning has not been eliminated by natural selection for two reasons. First, twinning is a consequence of double ovulation, which compensates for reproductive aging and benefits all but the youngest of mothers. Second, when the risk of early mortality of twins is not too high, twinning is associated with larger family sizes although women with twins give birth less often. This is because twin births bring two offspring rather than one,” concludes Courtiol. Reference: “Mothers with higher twinning propensity had lower fertility in pre-industrial Europe” by Ian J.

An international team that includes a University of Minnesota Twin Cities researcher has discovered a new big, meat-eating dinosaur, dubbed Meraxes gigas (illustrated above), that provides clues about the evolution and anatomy of predatory dinosaurs such as the Carcharodontosaurus and Tyrannosaurus rex. Credit: Jorge A Gonzalez Discovery provides insight into the evolution and anatomy of big, carnivorous dinosaurs. Researchers discovered a new huge, meat-eating dinosaur, dubbed Meraxes gigas. The new dinosaur provides fascinating clues about the evolution and biology of dinosaurs such as the Carcharodontosaurus and Tyrannosaurus rex—particularly, why these creatures had such large skulls and tiny arms. The study was co-led by University of Minnesota Twin Cities researcher Peter Makovicky and Argentinean colleagues Juan Canale and Sebastian Apesteguía and was published in Current Biology, a peer-reviewed scientific biology journal. Initially discovered in Patagonia in 2012, scientists have spent the last several years extracting, preparing, and analyzing the Meraxes specimen. The dinosaur is part of the Carcharodontosauridae family. This group of giant carnivorous theropods also includes Giganotosaurus, one of the largest known meat-eating dinosaurs and one of the reptilian stars of the recently released “Jurassic World: Dominion” movie.  Though not the largest among carcharodontosaurids, Meraxes was still an imposing animal measuring around 36 feet (11 meters) from snout to tail tip and weighing approximately 9,000 pounds (4,000 kg). The researchers recovered the Meraxes, alongside other dinosaurs including several long-necked sauropod specimens, from rocks that are around 90-95 million years old. Meraxes is among the most complete carcharodontosaurid skeletons paleontologists have found thus far in the southern hemisphere. It includes nearly the entirety of the animal’s skull, hips, and both left and right arms and legs.  “The neat thing is that we found the body plan is surprisingly similar to tyrannosaurs like T. rex,” said Peter Makovicky, one of the principal authors of the study and a professor in the University of Minnesota N.H. Winchell School of Earth and Environmental Sciences. “But, they’re not particularly closely related to T. rex. They’re from very different branches of the meat-eating dinosaur family tree. So, having this new discovery allowed us to probe the question of, ‘Why do these meat-eating dinosaurs get so big and have these dinky little arms?’” “The discovery of this new carcharodontosaurid, the most complete up to now, gives us an outstanding opportunity to learn about their systematics, paleobiology, and true size like never before,” said Sebastian Apesteguía, a co-author of the study and a researcher at Maimónides University in Argentina. Evolution of Large Skulls and Tiny Arms With the statistical data that Meraxes provided, the researchers found that large, mega-predatory dinosaurs in all three families of therapods grew in similar ways. As they evolved, their skulls grew larger and their arms progressively shortened. The possible uses of the tiny forelimbs in T. rex and other large carnivorous dinosaurs have been the topic of much speculation and debate.  “What we’re suggesting is that there’s a different take on this,” Makovicky said. “We shouldn’t worry so much about what the arms are being used for, because the arms are actually being reduced as a consequence of the skulls becoming massive. Whatever the arms may or may not have been used for, they’re taking on a secondary function since the skull is being optimized to handle larger prey.” The Mystery of Carcharodontosaurid Extinction The researchers also found that carcharodontosaurids including species from Patagonia evolved very quickly, but then disappeared suddenly from the fossil record very soon after. “Usually when animals are on the verge of extinction, it’s because their evolutionary rates are quite slow, meaning they aren’t adapting very quickly to their environment,” explained  Juan Canale, the study’s lead author and a researcher at the National University of Río Negro. “Here, we have evidence that Meraxes and its relatives were evolving quite fast, and yet within a few million years of being around, they disappeared, and we don’t know why. It’s one of these finds where you answer some questions, but it generates more questions for the future.” For more on this research, see Giant New Carnivorous Dinosaur Discovered With Tiny Arms Like T. rex.
