light The impact of exchanging the light and heavy chains on the structures of bovine ultralong antibodies By journals.iucr.org Published On :: 2024-07-01 The third complementary-determining regions of the heavy-chain (CDR3H) variable regions (VH) of some cattle antibodies are highly extended, consisting of 48 or more residues. These `ultralong' CDR3Hs form β-ribbon stalks that protrude from the surface of the antibody with a disulfide cross-linked knob region at their apex that dominates antigen interactions over the other CDR loops. The structure of the Fab fragment of a naturally paired bovine ultralong antibody (D08), identified by single B-cell sequencing, has been determined to 1.6 Å resolution. By swapping the D08 native light chain with that of an unrelated antigen-unknown ultralong antibody, it is shown that interactions between the CDR3s of the variable domains potentially affect the fine positioning of the ultralong CDR3H; however, comparison with other crystallographic structures shows that crystalline packing is also a major contributor. It is concluded that, on balance, the exact positioning of ultralong CDR3H loops is most likely to be due to the constraints of crystal packing. Full Article text

light DOMAS: a data management software framework for advanced light sources By journals.iucr.org Published On :: 2024-02-01 In recent years, China's advanced light sources have entered a period of rapid construction and development. As modern X-ray detectors and data acquisition technologies advance, these facilities are expected to generate massive volumes of data annually, presenting significant challenges in data management and utilization. These challenges encompass data storage, metadata handling, data transfer and user data access. In response, the Data Organization Management Access Software (DOMAS) has been designed as a framework to address these issues. DOMAS encapsulates four fundamental modules of data management software, including metadata catalogue, metadata acquisition, data transfer and data service. For light source facilities, building a data management system only requires parameter configuration and minimal code development within DOMAS. This paper firstly discusses the development of advanced light sources in China and the associated demands and challenges in data management, prompting a reconsideration of data management software framework design. It then outlines the architecture of the framework, detailing its components and functions. Lastly, it highlights the application progress and effectiveness of DOMAS when deployed for the High Energy Photon Source (HEPS) and Beijing Synchrotron Radiation Facility (BSRF). Full Article text
light VerSoX B07-B: a high-throughput XPS and ambient pressure NEXAFS beamline at Diamond Light Source By journals.iucr.org Published On :: 2024-03-26 The beamline optics and endstations at branch B of the Versatile Soft X-ray (VerSoX) beamline B07 at Diamond Light Source are described.

light Scattered high-energy synchrotron radiation at the KARA visible-light diagnostic beamline By journals.iucr.org Published On :: 2024-03-26 To characterize an electron beam, visible synchrotron light is often used and dedicated beamlines at synchrotron sources are becoming a more common feature as instruments and methods for the diagnostics are, along with the accelerators, further developed. At KARA (Karlsruhe Research Accelerator), such a beamline exists and is based on a typical infrared/visible-light configuration. From experience at such beamlines no significant radiation was expected (dose rates larger than 0.5 µSv h−1). This was found not to be the case and a higher dose was measured which fortunately could be shielded to an acceptable level with 0.3 mm of aluminium foil or 2.0 mm of Pyrex glass. The presence of this radiation led to further investigation by both experiment and calculation. A custom setup using a silicon drift detector for energy-dispersive spectroscopy (Ketek GmbH) and attenuation experiments showed the radiation to be predominantly copper K-shell fluorescence and is confirmed by calculation. The measurement of secondary radiation from scattering of synchrotron and other radiation, and its calculation, is important for radiation protection, and, although a lot of experience exists and methods for radiation protection are well established, changes in machine, beamlines and experiments mean a constant appraisal is needed.

light Teaching about the birth of synchrotron light: the role of Frascati and a missed opportunity By journals.iucr.org Published On :: 2024-05-21 The users of synchrotron light are now tens of thousands throughout the world. Paradoxically, many of them do not know much about the early history of their domain. This is regrettable, since education about the initial developments makes it easier to fully understand synchrotron radiation and effectively use its amazing features. Scarcely known, in particular, is the key role of scientists working in Frascati, Italy. Partly based on his personal experiences, the author reports here relevant aspects of this story, including a pioneering French–Italian experiment that started in the early 1960s, and the Frascati contributions in the 1970s and 1980s to the birth of synchrotron light research. Finally, the unwise strategic decisions that prevented Italy from achieving absolute leadership in this domain – in spite of its unique initial advantages – are analyzed. Full Article text
light Developing an in situ LED irradiation system for small-angle X-ray scattering at B21, Diamond Light Source By journals.iucr.org Published On :: 2024-05-31 Beamline B21 at the Diamond Light Source synchrotron in the UK is a small-angle X-ray scattering (SAXS) beamline that specializes in high-throughput measurements via automated sample delivery systems.

light A versatile sample-delivery system for X-ray photoelectron spectroscopy of in-flight aerosols and free nanoparticles at MAX IV Laboratory By journals.iucr.org Published On :: 2024-08-07 Aerosol science is of utmost importance for both climate and public health research, and in recent years X-ray techniques have proven effective tools for aerosol-particle characterization. To date, such methods have often involved the study of particles collected onto a substrate, but a high photon flux may cause radiation damage to such deposited particles and volatile components can potentially react with the surrounding environment after sampling. These and many other factors make studies on collected aerosol particles challenging. Therefore, a new aerosol sample-delivery system dedicated to X-ray photoelectron spectroscopy studies of aerosol particles and gas molecules in-flight has been developed at the MAX IV Laboratory. The aerosol particles are brought from atmospheric pressure to vacuum in a continuous flow, ensuring that the sample is constantly renewed, thus avoiding radiation damage, and allowing measurements on the true unsupported aerosol. At the same time, available gas molecules can be used for energy calibration and to study gas-particle partitioning. The design features of the aerosol sample-delivery system and important information on the operation procedures are described in detail here. Furthermore, to demonstrate the experimental range of the aerosol sample-delivery system, results from aerosol particles of different shape, size and composition are presented, including inorganic atmospheric aerosols, secondary organic aerosols and engineered nanoparticles.

light Development of an advanced in-line multilayer deposition system at Diamond Light Source By journals.iucr.org Published On :: 2024-08-09 A state-of-the-art multilayer deposition system with a 4200 mm-long linear substrate translator housed within an ultra-high vacuum chamber has been developed. This instrument is engineered to produce single and multilayer coatings, accommodating mirrors up to 2000 mm in length through the utilization of eight rectangular cathodes. To ensure the quality and reliability of the coatings, the system incorporates various diagnostic tools for in situ thickness uniformity and stress measurement. Furthermore, the system features an annealing process capable of heating up to 700°C within the load-lock chamber. The entire operation, including pump down, deposition and venting processes, is automated through user-friendly software. In addition, all essential log data, power of sputtering source, working pressure and motion positions are automatically stored for comprehensive data analysis. Preliminary commissioning results demonstrate excellent lateral film thickness uniformity, achieving 0.26% along the translation direction over 1500 mm in dynamic mode. The multilayer deposition system is poised for use in fabricating periodic, lateral-graded and depth-graded multilayers, specifically catering to the beamlines for diverse scientific applications at Diamond Light Source.

light C-SPAM: an open-source time-resolved specimen vitrification device with light-activated molecules By journals.iucr.org Published On :: 2023-12-14 Molecular structures can be determined in vitro and in situ with cryo-electron microscopy (cryo-EM).

light Fixed-target pump–probe SFX: eliminating the scourge of light contamination By journals.iucr.org Published On :: 2024-07-09 X-ray free-electron laser (XFEL) light sources have enabled the rapid growth of time-resolved structural experiments, which provide crucial information on the function of macromolecules and their mechanisms. Here, the aim was to commission the SwissMX fixed-target sample-delivery system at the SwissFEL Cristallina experimental station using the PSI-developed micro-structured polymer (MISP) chip for pump–probe time-resolved experiments. To characterize the system, crystals of the light-sensitive protein light–oxygen–voltage domain 1 (LOV1) from Chlamydomonas reinhardtii were used. Using different experimental settings, the accidental illumination, referred to as light contamination, of crystals mounted in wells adjacent to those illuminated by the pump laser was examined. It was crucial to control the light scattering from and through the solid supports otherwise significant contamination occurred. However, the results here show that the opaque MISP chips are suitable for defined pump–probe studies of a light-sensitive protein. The experiment also probed the sub-millisecond structural dynamics of LOV1 and indicated that at Δt = 10 µs a covalent thioether bond is established between reactive Cys57 and its flavin mononucleotide cofactor. This experiment validates the crystals to be suitable for in-depth follow-up studies of this still poorly understood signal-transduction mechanism. Importantly, the fixed-target delivery system also permitted a tenfold reduction in protein sample consumption compared with the more common high-viscosity extrusion-based delivery system. This development creates the prospect of an increase in XFEL project throughput for the field. Full Article text
light Capturing the blue-light activated state of the Phot-LOV1 domain from Chlamydomonas reinhardtii using time-resolved serial synchrotron crystallography By journals.iucr.org Published On :: 2024-07-22 Light–oxygen–voltage (LOV) domains are small photosensory flavoprotein modules that allow the conversion of external stimuli (sunlight) into intracellular signals responsible for various cell behaviors (e.g. phototropism and chloroplast relocation). This ability relies on the light-induced formation of a covalent thioether adduct between a flavin chromophore and a reactive cysteine from the protein environment, which triggers a cascade of structural changes that result in the activation of a serine/threonine (Ser/Thr) kinase. Recent developments in time-resolved crystallography may allow the activation cascade of the LOV domain to be observed in real time, which has been elusive. In this study, we report a robust protocol for the production and stable delivery of microcrystals of the LOV domain of phototropin Phot-1 from Chlamydomonas reinhardtii (CrPhotLOV1) with a high-viscosity injector for time-resolved serial synchrotron crystallography (TR-SSX). The detailed process covers all aspects, from sample optimization to data collection, which may serve as a guide for soluble protein preparation for TR-SSX. In addition, we show that the crystals obtained preserve the photoreactivity using infrared spectroscopy. Furthermore, the results of the TR-SSX experiment provide high-resolution insights into structural alterations of CrPhotLOV1 from Δt = 2.5 ms up to Δt = 95 ms post-photoactivation, including resolving the geometry of the thioether adduct and the C-terminal region implicated in the signal transduction process.

light Demonstration of neutron time-of-flight diffraction with an event-mode imaging detector By journals.iucr.org Published On :: 2024-07-11 Neutron diffraction beamlines have traditionally relied on deploying large detector arrays of 3He tubes or neutron-sensitive scintillators coupled with photomultipliers to efficiently probe crystallographic and microstructure information of a given material. Given the large upfront cost of custom-made data acquisition systems and the recent scarcity of 3He, new diffraction beamlines or upgrades to existing ones demand innovative approaches. This paper introduces a novel Timepix3-based event-mode imaging neutron diffraction detector system as well as first results of a silicon powder diffraction measurement made at the HIPPO neutron powder diffractometer at the Los Alamos Neutron Science Center. Notably, these initial measurements were conducted simultaneously with the 3He array on HIPPO, enabling direct comparison. Data reduction for this type of data was implemented in the MAUD code, enabling Rietveld analysis. Results from the Timepix3-based setup and HIPPO were benchmarked against McStas simulations, showing good agreement for peak resolution. With further development, systems such as the one presented here may substantially reduce the cost of detector systems for new neutron instrumentation as well as for upgrades of existing beamlines.

light VMXm – A sub-micron focus macromolecular crystallography beamline at Diamond Light Source By journals.iucr.org Published On :: 2024-10-30 VMXm joins the suite of operational macromolecular crystallography beamlines at Diamond Light Source. It has been designed to optimize rotation data collections from protein crystals less than 10 µm and down to below 1 µm in size. The beamline has a fully focused beam of 0.3 × 2.3 µm (vertical × horizontal) with a tuneable energy range (6–28 keV) and high flux (1.6 × 1012 photons s−1 at 12.5 keV). The crystals are housed within a vacuum chamber to minimize background scatter from air. Crystals are plunge-cooled on cryo-electron microscopy grids, allowing much of the liquid surrounding the crystals to be removed. These factors improve the signal-to-noise during data collection and the lifetime of the microcrystals can be prolonged by exploiting photoelectron escape. A novel in vacuo sample environment has been designed which also houses a scanning electron microscope to aid with sample visualization. This combination of features at VMXm allows measurements at the physical limits of X-ray crystallography on biomacromolecules to be explored and exploited. Full Article text
light Correlative X-ray micro-nanotomography with scanning electron microscopy at the Advanced Light Source By journals.iucr.org Published On :: 2024-10-29 Geological samples are inherently multi-scale. Understanding their bulk physical and chemical properties requires characterization down to the nano-scale. A powerful technique to study the three-dimensional microstructure is X-ray tomography, but it lacks information about the chemistry of samples. To develop a methodology for measuring the multi-scale 3D microstructure of geological samples, correlative X-ray micro- and nanotomography were performed on two rocks followed by scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS) analysis. The study was performed in five steps: (i) micro X-ray tomography was performed on rock sample cores, (ii) samples for nanotomography were prepared using laser milling, (iii) nanotomography was performed on the milled sub-samples, (iv) samples were mounted and polished for SEM analysis and (v) SEM imaging and compositional mapping was performed on micro and nanotomography samples for complimentary information. Correlative study performed on samples of serpentine and basalt revealed multiscale 3D structures involving both solid mineral phases and pore networks. Significant differences in the volume fraction of pores and mineral phases were also observed dependent on the imaging spatial resolution employed. This highlights the necessity for the application of such a multiscale approach for the characterization of complex aggregates such as rocks. Information acquired from the chemical mapping of different phases was also helpful in segmentation of phases that did not exhibit significant contrast in X-ray imaging. Adoption of the protocol used in this study can be broadly applied to 3D imaging studies being performed at the Advanced Light Source and other user facilities. Full Article text

October's operational hash rate averaged 6.8 EH/s, with adjustments made for demand response events and performance optimization measures to enhance profitability. Construction on the company's 20 MW HPC hosting facility, CB-1, remains on schedule for Q1 2025, and a larger 50 MW HPC facility, CB-2, is expected by Q2 2025. The recent sale of TeraWulf's equity interest in Nautilus and new financing through convertible notes are anticipated to support these growth initiatives. Sean Farrell, Senior Vice President of Operations at TeraWulf, explained in the press release, "October marked another productive month, with TeraWulf mining 150 bitcoin and sustaining an average daily production of around 5 bitcoin . . . In line with our previously outlined plans, we are accelerating the transition to more efficient mining hardware by replacing older miners at Lake Mariner with S19 XP models. We are also working closely with Bitmain's warranty department on a recovery plan to repair and replace 1.5 EH of mining equipment with a target completion by the end of the year. Furthermore, we have established a dedicated Business Development and Performance Optimization team focused on integrating advanced IT and software solutions to improve our operational hash rate and overall efficiency. Building 5, which has been designed to handle higher heat exhaust of the latest generation miners, remains on track to be operational in Q1 2025." Why Crypto Mining? The cryptocurrency mining sector has seen recent momentum, bolstered by the U.S. election results and the evolving landscape for Bitcoin. As Benzinga reported on November 6, bitcoin mining stocks experienced notable gains following the U.S. presidential election, which led to Bitcoin reaching record highs. The outcome was anticipated to benefit U.S.-focused mining companies as pro-crypto policies, including a preference for domestic bitcoin production, gained prominence. Benzinga noted that Trump had previously expressed support for more bitcoin mining within the U.S., a stance that influenced broader market optimism in the days following his election. On November 4, Yahoo! Finance highlighted the growing trend among Bitcoin miners to integrate artificial intelligence (AI) to power a "new industrial revolution." As described by Rob Nelson, who emphasized the impact of cryptocurrency mining as a vehicle for both economic and technological change. This trend has driven miners to secure deals within the AI sector, given the synergies in computational power required for both cryptocurrency and AI initiatives. Nelson projected that this cross-industry expansion could have far-reaching effects, creating value for both miners and AI-focused enterprises. Additionally, a November 6 report from Time explored the significance of the recent Presidential election outcome for the crypto industry's future regulatory environment. According to Time, Trump's support for the industry included ambitions to boost the country's bitcoin mining footprint, which aligned with crypto PACs' efforts to secure pro-crypto candidates. The article reported that these advocacy groups saw the election as an opportunity to reshape crypto regulation and encourage growth in U.S.-based bitcoin mining. TeraWulf's Catalysts TeraWulf's recent initiatives set a foundation for further growth and operational efficiency. According to the company's investor presentation, the sale of its 25% equity interest in the Nautilus facility enhances liquidity. This enables TeraWulf to reinvest in its flagship Lake Mariner site for both HPC and AI expansion. The transaction also reduces exposure to the expiring Nautilus 2¢ power contract by 2027, positioning the company to benefit from projected power price increases at Lake Mariner. This strategic realignment is anticipated to improve fleet efficiency, with an upgraded mining fleet targeting 13 EH/s by Q1 2025, supported by the deployment of next-gen S21 Pro miners. What Experts Are Saying... On November 5, 2024, Roth MKM analyst Darren Aftahi assigned TeraWulf a "Buy" rating and set a price target of US$7.50. Roth highlighted optimism around the company's expansion and potential in high-performance computing (HPC) and bitcoin mining. Roth noted that TeraWulf's planned 72.5 MW of HPC capacity by Q2 2025 could generate annualized revenue of approximately US$90 million, with over US$60 million in profit. [OWNERSHIP_CHART-11184] The report highlighted the completion of TeraWulf's initial 2.5 MW HPC project and its upcoming 20 MW facility, which remains on track for Q1 2025. Roth analysts pointed to the operational progress at TeraWulf's Lake Mariner facility, emphasizing the company's improvements in mining efficiency with new S19 XP models, which brought its machine efficiency to 22 J/TH.

light In-Flight Internet Services Co. Beats Expectations in Q3/24 By www.streetwisereports.com Published On :: Fri, 08 Nov 2024 00:00:00 PST Source: Scott Searle 11/08/2024 In line-to-better than expected financial results are good enough pre-launch of the satellite broadband solution, expected in Q4/24, noted a Roth MKM report.Gogo Inc. (GOGO:NASDAQ) reported its Q3/24 financial results, and they slightly exceeded expectations, reported Scott Searle, managing director at Roth MKM, in a Nov. 5 research note. The company provides in-flight connectivity services to business aviation markets through its North American terrestrial air-to-ground network. 137% Potential Return Roth maintained its target price of US$15.50 per share on Gogo, noted Searle. "We believe this provides a reasonable 12-plus-month target given the expected impact from two major new product cycles as we enter 2025," he wrote, referring to Galileo, the company's global inflight broadband service, and its 5G product line. In comparison, the company's share price at the time of the report was about US$6.55 per share. From this price, the return to target reflects 137% upside. Gogo remains a Buy. Quarter's Highlights Searle reported that Gogo's Q3/24 service revenue was a beat. At US$81.9 million (US$81.9M), it was slightly higher than that in Q2/24 and driven by modestly better-than-expected aircraft online, Searle reported. This revenue exceeded Roth's estimate by about US$300,000. Also of note, Galileo is on track to launch in Q4/24, and Gogo continues to grow its portfolio of supplemental type certificates and partners around the world. A Look Ahead Gogo's outlook for 2024 of US$400-410M encompasses consensus' estimate, noted Searle. The company, though, has "pulled long-term guidance ahead of the Satcom Direct [acquisition] closing." Roth expects Galileo and 5G will lead recovery, expected in late 2025. In other news, noted Searle, Gogo Chairman and Chief Executive Officer Oakleigh Thorne will present at Roth's NYC Tech Event on Nov. 20.

light Queena Kim, Off-Ramp's first producer, sheds light on the show's beginnings By www.scpr.org Published On :: Wed, 28 Jun 2017 15:33:26 -0700 Off-Ramp producer Queena Kim acts on behalf of millions of Angelenos. The meter didn't stand a chance. ; Credit: John Rabe/KPCC John Rabe | Off-Ramp®Off-Ramp began eleven years ago, just as digital technology was beginning to overtake radio. No more cassette tape or mini-discs; host John and producer Queena Kim thought they could take on all of Los Angeles with two digital audio recorders and a different approach to public radio. Short-handed as they were, John and Queena had to adopt slash-and-burn tactics to get each show produced on time. The majority of interviews were conducted in the field; at the homes, workplaces, and favorite hang-outs of their subjects (instead of waiting for guests to come to the station) and many of the stories were edited as simple two-way interviews with life in Southern California picked up as ambient, background noise. After all, a show called Off-Ramp had better be ready to brave some LA traffic. At this juncture, John feels free to say what he has always wanted to, but hasn't for fear of self-aggrandizement: "I think we were trendsetters. I think Marketplace and NPR heard the stuff we were doing, and started doing stuff like it." Once again, Kim chalks it up to being in the right place at the right time technologically, and the two person team's willingness to break out of the old-school, public radio way writing a story: with a very clear sonic difference between studio narration and field audio. Of course, it wasn't just Marantz recorders and minimal rewriting that gave Off-Ramp its flavor. There was a whole lot of weird spewing up out of Los Angeles during the show's formative years and Kim's tenure (2006-2010). She recalls covering a ten-theremin orchestra at Disney Hall, and the excitement of working on a show that let her (and the listeners, vicariously) do things she always wanted to do. "It was almost like having a free pass to the city." In order to capture what was new and exciting, John and Queena both agree that it was absolutely vital to abandon the reporter's instinct for safely packaging the story ahead of time. John cites his editor at Minnesota Public Radio's philosophy, Mike Edgerly; "Go find what the story is, go out and explore and figure out what the story is. Don't figure it out at your desk first." The collaboration between John's ideas and Kim's sense of logistics formed a dialectic relationship, valuing the "third, better idea" over either of their original perspectives. In light of that, John says Queena Kim was the perfect person with whom to start Off-Ramp. This content is from Southern California Public Radio. View the original story at SCPR.org. Full Article
light Virtual 'UniverseMachine' sheds light on galaxy evolution By news.science360.gov Published On :: 2019-09-04T07:00:00Z Full Text:How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation has long been a puzzle, but a University of Arizona-led team of scientists is one step closer to finding answers, thanks to supercomputer simulations. Observing real galaxies in space can only provide snapshots in time, so researchers who study how galaxies evolve over billions of years need to use computer simulations. Traditionally, astronomers have used simulations to invent theories of galaxy formation and test them, but they have had to proceed one galaxy at a time. Peter Behroozi of the university's Steward Observatory and colleagues overcame this hurdle by generating millions of different universes on a supercomputer, each according to different physical theories for how galaxies form. The findings challenge fundamental ideas about the role dark matter plays in galaxy formation, the evolution of galaxies over time and the birth of stars. The study is the first to create self-consistent universes that are exact replicas of the real ones -- computer simulations that each represent a sizeable chunk of the actual cosmos, containing 12 million galaxies and spanning the time from 400 million years after the Big Bang to the present day. The results from the "UniverseMachine," as the authors call their approach, have helped resolve the long-standing paradox of why galaxies cease to form new stars even when they retain plenty of hydrogen gas, the raw material from which stars are forged. The research is partially funded by NSF's Division of Physics through grants to UC Santa Barbara's Kavli Institute for Theoretical Physics and the Aspen Center for Physics.Image credit: NASA/ESA/J.

light Technique uses magnets, light to control and reconfigure soft robots By news.science360.gov Published On :: 2019-09-03T07:00:00Z Full Text:National Science Foundation (NSF)-funded researchers from North Carolina State and Elon universities have developed a technique that allows them to remotely control the movement of soft robots, lock them into position for as long as needed and later reconfigure the robots into new shapes. The technique relies on light and magnetic fields. "By engineering the properties of the material, we can control the soft robot's movement remotely; we can get it to hold a given shape; we can then return the robot to its original shape or further modify its movement; and we can do this repeatedly. All of those things are valuable, in terms of this technology's utility in biomedical or aerospace applications," says Joe Tracy, a professor of materials science and engineering at NC State and corresponding author of a paper on the work. In experimental testing, the researchers demonstrated that the soft robots could be used to form "grabbers" for lifting and transporting objects. The soft robots could also be used as cantilevers or folded into "flowers" with petals that bend in different directions. "We are not limited to binary configurations, such as a grabber being either open or closed," says Jessica Liu, first author of the paper and a Ph.D. student at NC State. "We can control the light to ensure that a robot will hold its shape at any point."Image credit: Jessica A.C. Liu Full Article
