In this episode of SpaceTime, we dive into groundbreaking research revealing the true composition of the Earth's core, explore new insights into solar neutrinos, and uncover the complexities of Martian volcanoes.Earth's Core Contains Vast Hydrogen ReservoirA recent study published in Nature Communications indicates that Earth's core may hold up to 45 oceans' worth of hydrogen, challenging the long-held belief that water on our planet primarily came from asteroids and comets. Utilizing advanced laboratory techniques, researchers simulated the extreme conditions of the core to uncover its surprising hydrogen content, suggesting a significant internal source of water far beyond previous estimates.Neutrinos from the Sun's CoreA new dark matter experiment has successfully detected neutrinos originating from the Sun's core, marking a significant milestone in our understanding of these elusive particles. The LZ experiment at the Sanford Underground Research Facility captured signals from Brian 8 solar neutrinos, providing valuable data on solar processes and setting new limits for dark matter research. This breakthrough highlights the potential of neutrino studies in unraveling the mysteries of both dark matter and stellar dynamics.Complexity of Martian VolcanoesNew findings published in Geology reveal that young Martian volcanoes are far more complex than previously thought. Researchers have discovered that these volcanoes were shaped by long-lasting and evolving magma systems rather than single eruptions. By analyzing surface features and mineral compositions from orbit, scientists have reconstructed the intricate eruptive history of these volcanic systems, shedding light on the Red Planet's geological past.www.spacetimewithstuartgary.com✍️ Episode ReferencesNature Communications, GeologyBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support.(00:00:00) New study reveals Earth's core may contain vast amounts of hydrogen(00:08:30) Breakthrough in solar neutrino detection from the Sun's core(00:16:45) Insights into the complex eruptive history of Martian volcanoes(00:25:00) Science report: The link between caffeine consumption and reduced dementia risk(00:32:15) Study on the frequency of passionate love experiences in humans

This week's special guest, Andi Hektor, takes us on a deep dive into his journey from academia to entrepreneurship, how GScan is tackling critical infrastructure challenges, and why he chose Cambridge as the company's UK base.GScan is pioneering Muon tomography, an advanced scanning technology originally used for border security but now revolutionising non-destructive testing (NDT) in construction. The technology helps detect corrosion and structural weaknesses in bridges and buildings, preventing costly and environmentally harmful demolitions. “Bridges are often demolished as a precaution because engineers can't see inside them. We provide that visibility, potentially doubling their lifespan.”Initially setting up in London, Andi quickly realised Cambridge's startup ecosystem was the ideal home for GScan: “London's tech scene is great, but for deep tech, it's easy to get lost. In Cambridge, you can build a network fast. The Bradfield Centre has been amazing.” Hosted on Acast. See acast.com/privacy for more information.

Adrian Mendes, CEO of Perimeter Medical Imaging AI, is solving the problem of margin assessment in cancer surgery. Surgeons often have to perform a second surgery on breast cancer patients because they are unable to completely remove all of the cancerous cells the first time. The company has developed Optical Coherence Tomography (OCT) imaging technology that allows surgeons to see cells at a microscopic level in real-time during surgery, helping them remove the tumor and all surrounding cancerous tissue. Adrian explains, "The surgeon is trying to ensure that when they extract the tumor and the cancer, there is a margin of healthy cells around it. Studies have shown that if they can achieve that, and with breast cancer, that margin needs to be two millimeters generally, then the likelihood of them having left cancer cells back in the body goes down drastically. This is every surgeon's objective for cancer treatment. We help the surgeons ensure that they've achieved what they call clean margins." "Yes, it's quite significant. So, for breast cancer surgery alone, it's about one in every five surgeries are unsuccessful because the margins aren't clean, and then the patient has to come back for a second surgery. So, there are about 300,000 breast cancer surgeries per year in the United States. If you think about 20% of that, there are a lot of women that are having to go back for a second surgery every year. That's just in the United States. And it's a global problem." "What's unique about our technology is we use an imaging tech called OCT or Optical Coherence Tomography that allows images to be created down at around 15-micron width level. And that's small enough to be able to distinguish cells. And so with that, it just gives the surgeon so much more ability to see what they're looking at." "The next generation uses the same imaging modality, the OCT imaging, but it adds an artificial intelligence and AI layer to it. So what we've done is trained an AI algorithm to recognize suspicious areas inside images of breast tissue. And these suspicious areas are indicative of cancer. The way we train the model is we have a library of about 2 million images of breast tissue, both cancerous and healthy tissue, and we've got labels that have been provided by pathologists." #PerimeterMedical #Oncology #BreastCancerSurgery #OCT #Tumors #MedAI perimetermed.com Download the transcript here

Commentary by Dr. Candice Silversides

Ettore Biondi, California Institute of Technology Traveltime-based tomographic methods have been extensively explored and employed by researchers since the 80s. Such algorithms have been successfully applied to various geophysical applications, ranging from seismic exploration to global to regional seismological scales. However, given the advancements in computational architectures over the last 20 years, full-waveform methodologies are now dominating most of the subsurface-parameter inversion applications. These workflows seek to match all the waveforms present within active seismic data or synthetic Green’s functions obtained by cross-correlating ambient noise. Despite this decrease in the popularity of traveltime-based tomographic approaches, these methods have great potential to be successful when applied to distributed acoustic sensing (DAS) data for seismic applications. DAS instruments can operate on existing telecommunication fibers and transform them into large-scale high-resolution seismic arrays. We demonstrate such potential by applying an Eikonal traveltime double-difference tomography algorithm to DAS data recorded in the Long Valley caldera, located in the Eastern Sierra region of California. This active volcanic area has been extensively studied in the last 50 years and its recent unrest remains still poorly understood. We employ two DAS arrays composed of almost 9000 channels along a 90-km north-south transect across the caldera to characterize the subsurface structures present underneath the area. We use almost 2000 cataloged events and apply a machine-learning algorithm to accurately pick their P and S arrival times necessary for the tomography. The range and spatial resolution of the DAS arrays allow us to retrieve structures that could not be resolved by previous studies that employed only conventional station recordings. Our results agree well with previous studies and highlight the presence of a low-velocity basin along the Mono-Inyo craters. Both P- and S-wave models also show a low-velocity structure centered below Mono Lake, which agrees with historical gravity surveys. Moreover, the low Vp/Vs ratio inverted below the Long Valley caldera suggests a lack of newly intruded materials at depth above 10 km and a clear separation between the shallow low-velocity basins and the ≥10-km deep magmatic reservoir.

Abstract: X-ray tomography and x-ray fluorescence imaging are two non-invasive imaging techniques to study cellular structures and chemical element distributions, respectively. However, correlative X-ray tomography and fluorescence imaging for the same cell has yet to be routinely realized due to challenges in sample preparation and X-ray radiation damage. Here we report an integrated experimental and computational workflow for achieving correlative multi-modality X-ray imaging of a single cell. The method consists of the preparation of radiation-resistant single-cell samples using live-cell imaging-assisted chemical fixation and freeze-drying procedures, targeting and labeling cells for correlative x-ray tomography and x-ray fluorescence measurement, and computational reconstruction of the correlative and multi-modality images. With X-ray tomography, cellular structures including the overall structure and intracellular organelles are visualized, while X-ray fluorescence imaging reveals the distribution of multiple chemical elements within the same cell. Our correlative method demonstrates the feasibility and broad applicability of using X-rays to understand cellular structures and the roles of multiple chemical elements and related proteins in signaling and other biological processes.

Abstract: Cilia and flagella play a crucial role in the development and function of most eukaryotic organisms. The structural core of the flagellum, the axoneme, is conserved in most eukaryotes and careful regulation of dynein motors within the axoneme is required for proper ciliary beating. The sperm flagellum from the American eel (Anguilla rostrata) has been shown to lack many of the canonical axonemal proteins, including the radial spokes, the central pair complex, and possibly even the outer row of dynein arms, presenting a "minimal" flagellar system. Here, we present cryo-electron tomography analysis of the eel sperm flagellum. We identified two states for the eel sperm flagellum within our tomograms, narrow and wide, and found that the flagellum started narrow near the sperm head and widened distally. Subtomogram averages revealed that the eel sperm flagellum has retained remnants of the missing regulatory complexes, including a short radial spoke 3 complex, basal components of radial spokes 1 and 2, and an outer dynein arm docking complex. We also describe unique structural features of the A. rostrata sperm flagellum, such as a unique pattern of holes at the inner junction and an accessory complex located at the "outer" junction. Finally, we discuss the consequences of losing key regulatory factors for the eel sperm flagellum and hypothesize several evolutionary factors that may have led to their loss. Together, our results shed light onto the structure and function of the eel sperm axoneme and provide insight into the minimum requirements for proper ciliary beating.

S., Plesnila, N., Misgeld, T., Mueller-Reichert, T., Khalin, I., Schifferer, M. Abstract: Like other volume electron microscopy approaches, Automated Tape Collecting Ultramicrotomy (ATUM) enables imaging of serial sections deposited on thick plastic tapes by scanning electron microscopy (SEM). However, ATUM is unique by enabling hierarchical imaging and thus efficient screening for target structures as needed e.g., for correlated light and electron microscopy. However, SEM of sections on tape can only access the section surface, thereby limiting the axial resolution to the typical size of cellular vesicles, an order of magnitude lower than the acquired xy resolution. In contrast, serial-section electron tomography (ET), a transmission electron microscopy-based approach, yields isotropic voxels at full EM resolution, but requires deposition of sections on electron-permeant thin and fragile monolayer films - thus making screening of large section libraries difficult and prone to section loss. To combine the strength of both approaches, we developed ATUM-Tomo, a hybrid method, where sections are first reversibly attached to plastic tape via a dissolvable coating, and after screening detached and transferred to the ET-compatible thin films. Thus, ATUM-SEM of serial semi-thick sections and consecutive ET of one selected section combines SEM's fast target recognition and coarse rendering capability with ET's high-resolution volume visualizations - thus enabling multi-scale interrogation of cellular ultrastructure. As a proof-of-principle, we applied correlative ATUM-Tomo to study ultrastructural features of blood brain barrier (BBB) leakiness around microthrombi in a mouse model of traumatic brain injury. Microthrombi and associated sites of BBB leakiness were identified by confocal imaging of injected fluorescent and electron-dense nanoparticles, then relocalized by ATUM-SEM, and finally interrogated by correlated ATUM-Tomo, a workflow which created a seamless zoom-in on structural BBB pathology from the micro- to the nanometer scale. Overall, our new ATUM-Tomo approach will substantially advance ultrastructural analysis of biological phenomena that require cell- and tissue-level contextualization of the finest subcellular textures.

Abstract: Antibody-based imaging techniques rely on the availability of high-quality reagents whose performance is evaluated for the specific application. Because commercial antibodies are validated for a limited number of uses, in many cases individual laboratories have to employ extensive in-house antibody testing. Here we present a novel strategy to efficiently identify candidate antibodies for array tomography (AT) by introducing an application-specific proxy screening step. AT is a serial section volume microscopy technique that enables quantitative analysis of the cellular proteome in a highly dimensional manner. To identify suitable antibodies for AT-based analysis of synapses in mammalian brain samples, we introduce a heterologous cell-based assay designed to simulate unique features of AT such as chemical fixation and resin embedding that are likely to influence antibody binding. The assay was included as part of the initial screening strategy to generate monoclonal antibodies that can be used for AT. This approach simplifies the screening of candidate antibodies and has high predictive value for identifying antibodies suitable for AT analyses. In addition, we have created a comprehensive database of AT validated antibodies with a neuroscience focus and show that these antibodies have a high likelihood of success for postembedding applications in general, including immunogold electron microscopy. The generation of a large and growing toolbox of antibodies for use in AT will further expand the use of this powerful imaging technique. Copy rights belong to original authors.
