A Ludwig-Maximilians-Universitaet (LMU) in Munich team has shown that slight alterations in transfer-RNA molecules (tRNAs) allow them to self-assemble into a functional unit that can replicate information exponentially. tRNAs are key elements in the evolution of early life-forms. Life as we know it is based on a complex network of interactions, which take place at microscopic scales in biological cells, and involve thousands of distinct molecular species. In our bodies, one fundamental process is repeated countless times every day. In an operation known as replication, proteins duplicate the genetic information encoded in the DNA molecules stored in the cell nucleus — before distributing them equally to the two daughter cells during cell division. The information is then selectively copied (‘transcribed’) into what are called messenger RNA molecules (mRNAs), which direct the synthesis of the many different proteins required by the cell type concerned. A second type of RNA — transfer RNA (tRNA) — plays a central role in the ‘translation’ of mRNAs into proteins. Transfer RNAs act as intermediaries between mRNAs and proteins: they ensure that the amino-acid subunits of which each particular protein consists are put together in the sequence specified by the corresponding mRNA. How could such a complex interplay between DNA replication and the translation of mRNAs into proteins have arisen when living systems first evolved on the early Earth? We have here a classical example of the chicken-and-the-egg problem: Proteins are required for transcription of the genetic information, but their synthesis itself depends on transcription. LMU physicists led by Professor Dieter Braun have now demonstrated how this conundrum could have been resolved. They have shown that minor modifications in the structures of modern tRNA molecules permit them to autonomously interact to form a kind of replication module, which is capable of exponentially replicating information. This finding implies that tRNAs — the key intermediaries between transcription and translation in modern cells — could also have been the crucial link between replication and translation in the earliest living systems. It could therefore provide a neat solution to the question of which came first — genetic information or proteins? Strikingly, in terms of their sequences and overall structure, tRNAs are highly conserved in all three domains of life, i.e. the unicellular Archaea and Bacteria (which lack a cell nucleus) and the Eukaryota (organisms whose cells contain a true nucleus). This fact in itself suggests that tRNAs are among the most ancient molecules in the biosphere. Like the later steps in the evolution of life, the evolution of replication and translation — and the complex relationship between them — was not the result of a sudden single step. It is better understood as the culmination of an evolutionary journey. “Fundamental phenomena such as self-replication, autocatalysis, self-organization and compartmentalization are likely to have played important roles in these developments,” says Dieter Braun. “And on a more general note, such physical and chemical processes are wholly dependent on the availability of environments that provide non-equilibrium conditions.” In their experiments, Braun and his colleagues used a set of reciprocally complementary DNA strands modeled on the characteristic form of modern tRNAs. Each was made up of two ‘hairpins’ (so called because each strand could partially pair with itself and form an elongated loop structure), separated by an informational sequence in the middle. Eight such strands can interact via complementary base-pairing to form a complex. Depending on the pairing patterns dictated by the central informational regions, this complex was able to encode a 4-digit binary code. Each experiment began with a template — an informational structure made up of two types of the central informational sequences that define a binary sequence. This sequence dictated the form of the complementary molecule with which it can interact in the pool of available strands. The researchers went on to demonstrate that the templated binary structure can be repeatedly copied, i.e. amplified, by applying a repeating sequence of temperature fluctuations between warm and cold. “It is therefore conceivable that such a replication mechanism could have taken place on a hydrothermal microsystem on the early Earth,” says Braun. In particular, aqueous solutions trapped in porous rocks on the seafloor would have provided a favorable environment for such reaction cycles, since natural temperature oscillations, generated by convection currents, are known to occur in such settings. During the copying process, complementary strands (drawn from the pool of molecules) pair up with the informational segment of the template strands. In the course of time, the adjacent hairpins of these strands also pair up to form a stable backbone, and temperature oscillations continue to drive the amplification process. If the temperature is increased for a brief period, the template strands are separated from the newly formed replicate, and both can then serve as template strands in the next round of replication. The team was able to show that the system is capable of exponential replication. This is an important finding, as it shows that the replication mechanism is particularly resistant to collapse owing to the accumulation of errors. The fact that the structure of the replicator complex itself resembles that of modern tRNAs suggests that early forms of tRNA could have participated in molecular replication processes, before tRNA molecules assumed their modern role in the translation of messenger RNA sequences into proteins. “This link between replication and translation in an early evolutionary scenario could provide a solution to the chicken-and-the-egg problem,” says Alexandra Kühnlein. It could also account for the characteristic form of proto-tRNAs, and elucidate the role of tRNAs before they were co-opted for use in translation. Laboratory research on the origin of life and the emergence of Darwinian evolution at the level of chemical polymers also has implications for the future of biotechnology. “Our investigations of early forms of molecular replication and our discovery of a link between replication and translation brings us a step closer to the reconstruction of the origin of life,” Braun concludes.

Recent findings by Johns Hopkins University reveal that prehistoric worms played a crucial role in boosting oxygen levels through sediment mixing, thereby contributing significantly to the Great Ordovician Biodiversification Event and the explosion of new species approximately 480 million years ago. Prehistoric worms’ burrowing activities on ocean floors released oxygen, fostering the Great Ordovician Biodiversification Event, according a new study. One of Earth’s most consequential bursts of biodiversity—a 30-million-year period of explosive evolutionary changes spawning innumerable new species—may have the most modest of creatures to thank for the vital stage in life’s history: worms. The digging and burrowing of prehistoric worms and other invertebrates along ocean bottoms sparked a chain of events that released oxygen into the ocean and atmosphere and helped kick-start what is known as the Great Ordovician Biodiversification Event, roughly 480 million years ago, according to new findings Johns Hopkins University researchers published in the journal Geochimica et Cosmochimica Acta. “It’s really incredible to think how such small animals, ones that don’t even exist today, could alter the course of evolutionary history in such a profound way,” said senior author Maya Gomes, an assistant professor in the Department of Earth and Planetary Sciences. “With this work, we’ll be able to examine the chemistry of early oceans and reinterpret parts of the geological record.” To better understand how changes in oxygen levels influenced large-scale evolutionary events, Gomes and her research team updated models that detail the timing and pace of increasing oxygen over hundreds of millions of years. Sediment Mixing and Oxygen Levels They examined the relationship between the mixing of sediment caused, in part, by digging worms with a mineral called pyrite, which plays a key role in oxygen buildup. The more pyrite that forms and becomes buried under the mud, silt, or sand, the more oxygen levels rise. Scientists measured pyrite from nine sites along a Maryland shoreline of the Chesapeake Bay that serves as a proxy for early ocean conditions. Sites with even just a few centimeters of sediment mixing held substantially more pyrite than those without mixing and those with deep mixing. The findings challenge previous assumptions that the relationship between pyrite and sediment mixing remained the same across habitats and through time, Gomes said. Conventional wisdom held that as animals churned up sediments by burrowing in the ocean floor, newly unearthed pyrite would have been exposed to and destroyed by oxygen in the water, a process that would ultimately prevent oxygen from accumulating in the atmosphere and ocean. Mixed sediments have been viewed as evidence that oxygen levels were holding steady. The new data indicates that a small amount of sediment mixing in water with very low levels of oxygen would have exposed buried pyrite, sulfur, and organic carbon to just enough oxygen to kick-start the formation of more pyrite. “It’s kind of like Goldilocks. The conditions have to be just right. You have to have a little bit of mixing to bring the oxygen into the sediment, but not so much that the oxygen destroys all the pyrite and there’s no net buildup,” said Kalev Hantsoo, a doctoral candidate at Johns Hopkins and first author on the article. Oxygen Levels and Evolutionary Events When the researchers applied this new relationship between pyrite and the depth of sediment mixing to existing models, they found oxygen levels stayed relatively flat for millions of years and then rose during the Paleozoic era, with a steep rise occurring during the Ordovician period. The extra oxygen likely contributed to the Great Ordovician Biodiversification Event, when new species rapidly flourished, the researchers said. “There’s always been this question of how oxygen levels relate to the moments in history where evolutionary forces are ramped up and you see a greater diversity of life on the planet,” Gomes said. “The Cambrian period also had a massive speciation event, but the new models allow us to rule out oxygen and focus on other things that may have driven evolution during that time.” Reference: “Trends in estuarine pyrite formation point to an alternative model for Paleozoic pyrite burial” by Kalev Hantsoo, Maya Gomes, Dana Brenner, Jeffrey Cornwell, Cindy M.

A new study reveals that consciousness relies on synchronized communication between sensory and cognitive brain regions, which breaks down under general anesthesia. While sensory areas can detect surprises, the lack of coordination with higher-order regions leaves the brain unaware of these stimuli. A new study provides further evidence that consciousness depends on communication between the brain’s sensory and cognitive regions in the cortex. Our brains are constantly making predictions about our surroundings, enabling us to focus on and respond to unexpected events. A recent study explores how this predictive process functions during consciousness and how it changes under general anesthesia. The findings support the idea that conscious thought relies on synchronized communication between basic sensory areas and higher-order cognitive regions of the brain, facilitated by brain rhythms in specific frequency bands. Previously, members of the research team at The Picower Institute for Learning and Memory at MIT and at Vanderbilt University had described how brain rhythms enable the brain to remain prepared to attend to surprises. Cognition-oriented brain regions (generally at the front of the brain), use relatively low-frequency alpha and beta rhythms to suppress processing by sensory regions (generally toward the back of the brain) of stimuli that have become familiar and mundane in the environment (e.g. your co-worker’s music). When sensory regions detect a surprise (e.g. the office fire alarm), they use faster frequency gamma rhythms to tell the higher regions about it and the higher regions process that at gamma frequencies to decide what to do (e.g. exit the building). Anesthesia’s Impact on Brain Communication The new results published Oct. 7 in the Proceedings of the National Academy of Sciences, show that when animals were under propofol-induced general anesthesia, a sensory region retained the capacity to detect simple surprises but communication with a higher cognitive region toward the front of the brain was lost, making that region unable to engage in its “top-down” regulation of the activity of the sensory region and keeping it oblivious to simple and more complex surprises alike. “What we are doing here speaks to the nature of consciousness,” said co-senior author Earl K. Miller, Picower Professor in The Picower Institute for Learning and Memory and MIT’s Department of Brain and Cognitive Sciences. “Propofol general anesthesia deactivates the top-down processes that underlie cognition. It essentially disconnects communication between the front and back halves of the brain.” Earl K. Miller and Andre Bastos in a composite image. Credit: MIT Picower Institute Co-senior author Andre Bastos, an assistant professor in the psychology department at Vanderbilt and a former member of Miller’s MIT lab, added that the study results highlight the key role of frontal areas in consciousness. “These results are particularly important given the newfound scientific interest in the mechanisms of consciousness, and how consciousness relates to the ability of the brain to form predictions,” Bastos said. The brain’s ability to predict is dramatically altered during anesthesia. It was interesting that the front of the brain, areas associated with cognition, were more strongly diminished in their predictive abilities than sensory areas. This suggests that prefrontal areas help to spark an ‘ignition’ event that allows sensory information to become conscious. Sensory cortex activation by itself does not lead to conscious perception. These observations help us narrow down possible models for the mechanisms of consciousness.” Yihan Sophy Xiong, a graduate student in Bastos’s lab who led the study. said the anesthetic reduces the times in which inter-regional communication within the “In the awake brain, brain waves give short windows of opportunity for neurons to fire optimally – the ‘refresh rate’ of the brain, so to speak,” Xiong said “This refresh rate helps organize different brain areas to communicate effectively. Anesthesia both slows down the refresh rate, which narrows these time windows for brain areas to talk to each other, and makes the refresh rate less effective, so that neurons become more disorganized about when they can fire. When the refresh rate no longer works as intended, our ability to make predictions is weakened.” Learning from oddballs To conduct the research, the neuroscientists measured the electrical signals, “or spiking,” of hundreds of individual neurons and the coordinated rhythms of their aggregated activity (at alpha/beta and gamma frequencies), in two areas on the surface, or cortex, of the brain of two animals as they listened to sequences of tones. Sometimes the sequences would all be the same note, (e.g. AAAAA). Sometimes there’d be a simple surprise that the researchers called a “local oddball” (e.g. AAAAB). But sometimes the surprise would be more complicated, or a “global oddball.” For example, after seeing a series of AAAABs, there’d all of a sudden be AAAAA, which violates the global but not the local pattern. Prior work has suggested that a sensory region (in this case the temporoparietal area, or Tpt) can spot local oddballs on its own, Miller said. Detecting the more complicated global oddball requires the participation of a higher-order region (in this case the Frontal Eye Fields, or FEF). The animals heard the tone sequences both while awake and while under propofol anesthesia. There were no surprises about the waking state. The researchers reaffirmed that top-down alpha/beta rhythms from FEF carried predictions to the Tpt and that Tpt would increase gamma rhythms when an oddball came up, causing FEF (and the prefrontal cortex) to respond with upticks of gamma activity as well. But by several measures and analyses, the scientists could see these dynamics break down after the animals lost consciousness. Under propofol, for instance, spiking activity declined overall but when a local oddball came along, Tpt spiking still increased notably but now spiking in FEF didn’t follow suit as it does during wakefulness. Meanwhile, when a global oddball was presented during wakefulness, the researchers could use software to “decode” representation of that among neurons in FEF and the prefrontal cortex (another cognition-oriented region). They could also decode local oddballs in the Tpt. But under anesthesia the decoder could no longer reliably detect representation of local or global oddballs in FEF or the prefrontal cortex. Moreover, when they compared rhythms in the regions amid wakeful vs. unconscious states they found stark differences. When the animals were awake, oddballs increased gamma activity in both Tpt and FEF and alpha/beta rhythms decreased. Regular, non-oddball stimulation increased alpha/beta rhythms. But when the animals lost consciousness the increase in gamma rhythms from a local oddball was even greater in Tpt than when the animal was awake. “Under propofol-mediated loss of consciousness, the inhibitory function of alpha/beta became diminished and/or eliminated, leading to disinhibition of oddballs in sensory cortex,” the authors wrote. Other analyses of inter-region connectivity and synchrony revealed that the regions lost the ability to communicate during anesthesia. In all, the study’s evidence suggests that conscious thought requires coordination across the cortex, from front to back, the researchers wrote. “Our results therefore suggest an important role for prefrontal cortex activation, in addition to sensory cortex activation, for conscious perception,” the researchers wrote.
