Boeing Starliner crew members continue to stay occupied aboard the ISS, yet they express a desire to return home in the future.

View pictures in App save up to 80% data. On Wednesday, January 8, 2025, NASA astronauts Butch Wilmore, Nick Hague, Don Pettit, and Suni Williams engaged in a conversation from the International Space Station with NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy. (NASA) Having officially spent seven months aboard the International Space Station, the two NASA astronauts who traveled on Boeing's Starliner last June are preparing for a hectic schedule in the new year as they anticipate their return flight in the spring. Butch Wilmore and Suni Williams reached the International Space Station (ISS) on June 5 aboard the Starliner. However, they stayed on the station after NASA opted to return the spacecraft without its crew due to safety concerns. The two astronauts connected with fellow NASA members Nick Hague and Don Pettit for a conversation from the ISS with NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy on Wednesday. “I’d like to request Butch and Suni to clarify once and for all the questions that reporters keep bombarding me with regarding your situation. They’re worried about you being stranded, lacking clothes, and food,” Nelson stated. “Could you please put these concerns to rest for good? I sincerely hope you won’t have to address this again. How are you both doing?” Wilmore stepped in to clarify that during the duo's initial flight on Starliner, which was initially intended to last just eight days, they encountered some clothing challenges. This was due to Starliner needing to transport emergency equipment to ensure the bathroom was operational, resulting in the pair having to forgo some of their personal items. “It was common knowledge that we arrived here and exchanged a few components we required on the space station for some of our clothing. We ended up wearing those clothes for a period, but it didn't inconvenience us at all. Up here, clothes are more relaxed in fit. Unlike on Earth, where sweating can make things uncomfortable, here they are loose enough that you can wear them for weeks without any issue.” Since the arrival of Crew-9 last fall, the duo has been provided with a new wardrobe, according to him, and this mission will ultimately serve as the return journey for Williams and Wilmore. He also mentioned that everyone on the vessel is well-nourished. "I've never witnessed anyone consume as much food as Don Pettit does. It's incredible to see this man eat, especially considering how slim he is. It's truly a delight to behold," Wilmore remarked. Melroy reaffirmed her commitment to dispelling the “stranded” narrative that has circulated in various media outlets regarding the prolonged stay of the Starliner astronauts. “So what you're saying is that you're not tapping into 'Cast Away,' and you don't possess a volleyball marked with a handprint that you refer to as Wilson,” Melroy remarked. Williams, currently serving as the commander for what is now Expedition 72, remarked that there is an overwhelming amount of work to focus on, leaving little room for such contemplations. “Not at all, we have a full team here, so that’s not a concern. Plus, there’s plenty of work to tackle with the crew down below,” she mentioned. “We conducted numerous scientific experiments during SpaceX’s cargo resupply mission 31. Upcoming spacewalks are on the agenda as well. Things were quite hectic while we awaited Nick (Hague) to arrive. It’s truly been a pleasure working up here, especially alongside our colleagues on the opposite side of the space station.” Williams and Hague are scheduled to undertake at least one spacewalk later this month, while Wilson and Wilmore may participate in a second one the following week. “It’s an amazing team, and honestly, it doesn’t feel like we’re isolated. Sure, we want to return home eventually, since we’ve been away from our families for some time, but there’s plenty to accomplish while we’re here,” Williams remarked. “We need to finish all our tasks before we can head back.” The astronauts of Starliner were formally integrated into the Crew-9 team when the SpaceX Crew Dragon Freedom docked on September 29, piloted by Commander Hague, accompanied by mission specialist Aleksandr Gorbunov from Roscosmos. The two astronauts traveled with two vacant seats, allowing Wilmore and Williams to catch a ride back home. Crew-9 will remain at the International Space Station until Crew-10 arrives, which is scheduled to launch in late March. This suggests that Crew-9 might not come back to Earth until early April, as there typically is a handoff period of about a week following the arrival of a replacement crew. Consequently, Wilmore and Williams could end up spending nearly 10 months aboard the spacecraft. NASA's Pettit has joined the team after arriving via a Soyuz spacecraft, and he is scheduled to head back home on the same vehicle in March. This week, Williams has ascended to the second position for the total number of days spent in space by a NASA astronaut. With a remarkable 538 days accumulated over three missions to the ISS since 2006, she now follows in the footsteps of Peggy Whitson, a former NASA astronaut and current Axiom Space employee, who has an impressive record of over 675 days in space. Whitson is also set to add to her total as she prepares to take command of the Axiom 4 mission later this year.

Rapid and Proficient Sea Ice Predictions

Artificial intelligence enables the creation of a highly efficient and proficient substitute for a coupled Arctic sea ice prediction model through the use of generative diffusion techniques. View pictures in App save up to 80% data. (Left) The figures display the sea ice divergence (a, e, and i), shear rate (b, f, and j), sea-ice concentration (c, g, and k), and the semidiurnal variation in sea ice thickness (d, h, and l) as modeled by neXtSIM (a–d), the deterministic emulated forecast (e–h), and an ensemble member from the residual diffusion forecast (i–l). These data are pertinent to the date of December 30, 2017, at 03:00 UTC, with a forecast lead time of 50 days. (Right) A sample of the pan-Arctic validation sea ice thickness, as simulated by neXtSIM for a snapshot from January 2015, is presented on the right, alongside the 64 × 64 grid point surrogate domain (indicated by the red box) for frames (a) to (l). Credit: Finn et al. [2024], Figures 1 and 6. Editors' Highlights provide concise overviews of the latest research articles published by the editors of AGU journals. Source: Journal of Advances in Modeling Earth Systems Sea ice model surrogates developed during the past decade are disrupting polar forecasting at a pace akin to numerical methods developed at the dawn of computer-generated predictions of Earth’s frozen oceans. In 1964, Lieutenant William Knodle’s numerical implementation of Vasily Shuleikin’s equations for wind-driven drift beckoned rapid development of physically consistent daily Arctic ice edge forecasts. In their new study, Finn et al. [2024] used generative diffusion to illustrate the potential of a Lagrangian sea ice emulator to predict intraseasonal thickness, concentration, drift and deformation across the Arctic pack with the veracity of the numerical training model, but orders of magnitude faster. The authors added stochasticity to a deterministic surrogate of the neXtSIM Lagrangian sea ice model that was coupled to the NEMO ocean framework and forced with ERA5 atmospheric re-analyses. They trained a neural network to iteratively denoise to 1995-2014 neXtSIM simulations, tuned the resulting residual diffusion surrogate to 2015 neXtSIM output, and emulated neXtSIM 2016-2018 forecasts. The residual diffusion emulator closely mimicked observed multi-fractal sea ice deformation simulated by neXtSIM, in contrast to the simpler deterministic surrogate. Without supplying boundary conditions to the surrogate domain, diffusion surrogate forecasts produced sharp linear kinematic features and related sea ice concentration and thickness 50 days past initialization, as seen in figure above. The method beckons ensemble sea ice forecasts for a fraction of the computational cost of dynamical models.

Unleashing the Power of Language: The Impact of Words on Feelings, Decisions, and Behaviors

View pictures in App save up to 80% data. In a pioneering study featured in the renowned journal Cell Reports, scientists have achieved remarkable advancements in comprehending the interplay between neurotransmitters in the human brain and the emotional facets of language processing. The findings illuminate the intricate relationship between linguistic elements and emotional perception, indicating a deep link between neurotransmitter release and the emotional significance of the words we encounter in daily interactions. This global collaboration, spearheaded by the distinguished computational neuroscientist Read Montague at the Fralin Biomedical Research Institute, brought together more than 20 researchers and medical professionals, highlighting the collective effort behind this innovative research. The study concentrated on neurotransmitters like dopamine and serotonin, which are commonly linked to mood regulation and emotional reactions. Historically, it was believed that these neurochemicals indicated the positive or negative aspects of experiences. Nonetheless, recent discoveries suggest that these neurotransmitters are also vital in shaping how individuals understand the subtleties of language. This connection between brain chemistry and linguistic interpretation is fascinating and could indicate a more profound evolutionary advancement in human cognitive abilities. Montague and his team embarked on this research to examine the theory that brain systems, which initially developed for the purpose of survival and responding to environmental dangers or rewards, could also play a vital role in understanding the meanings of words. This idea holds particular importance for complex social creatures such as humans, who depend heavily on nuanced verbal communication for their everyday interactions and survival tactics. Effectively grasping the emotional nuances of language may not only facilitate human connections but also influence mental well-being. This research marks a groundbreaking effort to assess the simultaneous release of various neurotransmitters triggered by emotional language content. It was carried out on patients who were receiving deep brain stimulation surgery, enabling real-time monitoring of neurochemical activity in targeted areas of the brain. By presenting emotionally significant words on a screen throughout the procedure, the scientists successfully collected data on neurotransmitter fluctuations through sophisticated measurement methods. Recent discoveries have shed light on unexpected roles of the thalamus, a brain region generally recognized for its role in sensory processing. Historically, the thalamus has not been connected to language or emotion. However, new research has revealed that neurotransmitter levels fluctuate in reaction to different emotional words, indicating a complex interaction between various brain areas during language interpretation. This finding suggests that regions not typically associated with emotional and linguistic functions might still play a crucial role in processing important information, aiding in immediate decision-making. Participants in the study underwent deep brain stimulation, during which electrodes monitored neurotransmitter release in response to positive, negative, and neutral words. The findings revealed a complex interaction of neurotransmitters that correlated closely with the emotional weight of the words presented. This detailed insight marks a significant advancement in our comprehension of language processing, illuminating the distinct patterns emerging across different brain areas and their processing dynamics. As a crucial component of the validation process, the team carried out relevant studies employing rodent models. They leveraged advanced techniques such as optogenetics to selectively stimulate certain neurons and monitor their reactions, reflecting the processing patterns of the human brain. This research across different species supports the findings and enhances our comprehension of the neurochemical networks that shape our emotional interpretations of language. The research highlights that language transcends its role as a communication tool, acting instead as a powerful driver of behavior and choices. By uncovering the unique neuromodulator patterns associated with various emotional tones, the study enhances our comprehension of how people may respond in diverse ways to identical verbal messages based on the emotional nuances present. This insight could prove significant for fields like mental health, underlining the critical need to acknowledge the impact of emotional language. Earlier studies in neuroscience predominantly examined neurotransmission in relation to decision-making. In contrast, the present research takes a novel approach by focusing on the emotional impact of language, shedding light on cognitive dimensions that have often been neglected. The researchers argue that, in contrast to numerous other species, humans have a sophisticated ability to understand language that incorporates both context and emotional nuances. Consequently, our processing of emotionally charged words could reveal fundamental cognitive processes linked to survival, creating a connection between linguistic expression and biological needs. Additionally, the vocabulary utilized in the study was carefully curated from the Affective Norms for English Words (ANEW) database, which classifies words according to their emotional value. This thorough methodology enabled the research team to develop a framework that can examine how specific words provoke different emotional reactions, thereby enhancing the comprehension of human thought processes and language. As the scientific community enthusiastically examines these discoveries, the repercussions extend beyond neuroscience to impact psychology, linguistics, and therapeutic methodologies. Such research lays the groundwork for future investigations into the complex connections among emotional cognition, language understanding, and neurobiology. It paves the way for new explorations into how language molds human experiences and affects mental health results. As research progresses and gains further validation, it is essential to recognize the significant impact it could have across multiple disciplines, including cognitive neuroscience, psychology, and artificial intelligence. Gaining insights into how individuals emotionally connect with language might pave the way for innovative approaches in creating technologies that can more effectively understand and react to human emotions via language processing mechanisms. This convergence of neuroscience, linguistics, and emotional intelligence presents a thrilling avenue for scientific inquiry.

A Discovery of Hundreds of Dinosaur Footprints Dating Back 166 Million Years Has Been Made in England

View pictures in App save up to 80% data. Pawel Pajor - stock.adobe.com - for illustrative use only During the previous summer, an employee at a limestone quarry located in southeast England was excavating clay when he observed some unusual protrusions in the vicinity. Recently, a collaborative effort involving more than 100 researchers from the Universities of Birmingham and Oxford has confirmed that the bumps discovered are indeed dinosaur tracks, dating back approximately 166 million years to the Middle Jurassic era. Approximately 200 footprints have been uncovered across five distinct trails at Dewars Farm Quarry in Oxfordshire. This recent discovery sheds light on the behaviors of dinosaurs, offering valuable information regarding their speed, size, locomotion, and social interactions. “According to our speed estimates, it is likely that all dinosaurs were more inclined to walk than to run,” stated Kirsty Edgar, a micropaleontology professor at the University of Birmingham. Edgar suggests that the habitat of the dinosaurs may have been similar to the modern-day Florida Keys. Scientists uncovered five trackways preserved in the mud, with the longest measuring nearly 500 feet. Four of the trackways were created by long-necked herbivorous sauropods, probably belonging to the 60-foot, two-ton species known as Cetiosaurus. The fifth set was created by a meat-eating Megalosaurus, a predator that stretched 30 feet in length and had clawed feet with three toes. In 1824, it was William Buckland, a geologist from Oxford, who became the first to scientifically name the Megalosaurus, marking a significant moment in paleontology. In one section of the site, the tracks of carnivores and herbivores intersected, prompting inquiries into the nature of their interactions and whether they coexisted in the same environment. “Researchers have had knowledge of and have been investigating Megalosaurus longer than any other dinosaur species on the planet. However, recent findings demonstrate that there remains untapped evidence regarding these creatures, just waiting to be uncovered,” stated Emma Nicholls, a vertebrate paleontologist at the Oxford Museum of Natural History. View pictures in App save up to 80% data. Pawel Pajor – stock.adobe.com – for illustrative purposes only. The tracks left by the Megalosaurus measured approximately 25 inches in length, with a stride spanning about 8.8 feet. Researchers believe that this dinosaur moved at a speed of approximately three miles per hour, which is comparable to the typical walking speed of an adult human. It is also suggested that the sauropods may have traveled at a similar rate. Dinosaur footprints were initially found in the region in 1997 when workers at a limestone quarry stumbled upon over 40 sets of tracks. Some of these trackways extended nearly 600 feet long. The UK government has identified the Oxfordshire location as one of the globe's key dinosaur track sites, granting it the status of a Site of Special Scientific Interest. In general, the recent findings have shed light on the types of dinosaurs that roamed the U.K. during the Middle Jurassic era. Thanks to advancements in modern technology, prints can now be captured with unprecedented detail, enhancing the importance of the region. In the most recent excavation, over 20,000 images of 200 dinosaur footprints were taken. These images will be valuable resources for ongoing research and educational purposes related to dinosaurs.

The Unity Earth Science course has launched the Genesis Arboretum.

View pictures in App save up to 80% data. Students Claire Van Voorst and Eve Baart, both in their junior year, are busy digging a hole for a sapling at Unity Christian High School as they work together to establish an arboretum. ORANGE CITY—This fall, Unity Christian High School welcomed 26 new trees to its campus, thanks to the efforts of Kevin Haan’s earth science class, who successfully achieved their dream of creating the Genesis Arboretum. The foundation of the project was established last year. "Haan mentioned that in last year's earth science class, the primary focus was on obtaining permission to initiate a tree planting project, aiming ultimately to establish an arboretum. The students dedicated their efforts to all the preparatory work necessary for this initiative." During the 2023-24 academic year, students in Haan's earth science class explored the numerous advantages of trees, identified suitable planting sites, and showcased the ways in which an arboretum could foster interdisciplinary learning experiences. They compiled their findings into a formal proposal and delivered a 30-minute presentation to Unity Christian's superintendent, director of learning, and head groundskeeper, effectively making their case. “To make a long story short, they agreed and now offer landscaping services along with a wide selection of plants, shrubs, and trees.” As the arboretum initiative started to take shape, it was evident that a name was necessary. Students proposed various options and held a vote to decide. Ultimately, they chose the name Genesis Arboretum, referencing the opening book of the Bible, which describes how “The Lord God made all kinds of trees grow out of the ground — trees that were pleasing to the eye and good for food.” Haan mentioned that the name also embodies his school’s dedication to stewardship and responsible caretaking. "We serve as guardians and caretakers of creation. Our goal is to convey two important ideas to the students: firstly, that this is indeed rooted in science and biology; and secondly, as Christians, we have a responsibility to nurture and protect the environment." Trees play a vital role in an ecosystem, offering shade, serving as habitats for various birds and wildlife, minimizing soil erosion, and enhancing air quality. As the development of Genesis Arboretum progressed, an important task was to choose the tree species that would thrive on the grounds of Unity Christian. “Haan mentioned, ‘The Iowa DNR provided us with a list of native trees suitable for Iowa, as the main goal of this grant is to promote diversity among native species. We aimed to include a wide variety of species, and we managed to acquire nearly one of each type available.’” View pictures in App save up to 80% data. Junior Caleb Altena digs a hole while junior Brody Emmelkamp looks on with a shovel on the grounds of Unity Christian High School. Students in Kevin Haan’s earth science course established an arboretum. Photo submitted The area around the school building features a diverse selection of new trees, including three types of oak, a Kentucky coffee tree, two varieties of honey locust, a birch, and a spruce. Arboreta are classified into four accreditation levels, and Genesis Arboretum holds a Level 1 status. To achieve this level, an arboretum must contain a minimum of 25 species of woody plants, whether they be trees or shrubs, and be located in a site that is accessible to the public. This year, Senior Ava Postma is enrolled in Haan’s earth science class, and her family runs Arden Tree Farms located in Washington state. For the project, Ground Effects obtained some of the trees from her family's business. Postma shared, “My great-great-grandfather was one of the original founders, and this tree farm has been a cherished family-owned business for four generations. I aspire to uphold that legacy and hope to play a role in its future. It's incredible to witness how everything is intertwined.” Haan emphasized species diversity while choosing the trees, partly to fulfill the requirements for achieving Level 1 arboretum status. Nevertheless, his decision was influenced by additional considerations as well. "We aim to avoid the situation we're currently facing with the emerald ash borer," stated Haan. The emerald ash borer is a harmful invasive insect that targets ash trees and has been found in all 99 counties of Iowa. Increasing species diversity within arboretums enhances their ability to withstand diseases or pests that can gradually eliminate a specific type of tree. Take the American chestnut, for instance; it was once a prominent tree species in the eastern United States until a foreign chestnut blight fungus started to proliferate in the early 1900s. As a result, this species is now regarded as functionally extinct. Unity Christian has planted new trees throughout its 10-acre campus located on the western side of Orange City. The decision on where to plant these trees was made in partnership with the school's administration and grounds crew. Care was taken to steer clear of areas designated for athletic teams and potential future construction sites. Haan explained, “These areas may not be practical for the daily operations of Unity, yet they still serve a purpose for biology and ecology. We essentially tried to maximize the available space wherever possible. We added a significant amount of greenery on the east side of the property, adjacent to Michigan Avenue, and also planted several trees along the western edge of the parking lot.” The trees next to the parking area also line a cornfield, and in time, they will form a magnificent canopy over an area that was once overrun with weeds and prone to erosion. Day of Planting On a school morning in late October, Haan's earth science students planted saplings that typically ranged in height from 6 to 8 feet. “We had about 32 children out there, digging holes and relocating trees using the Gators,” Haan remarked. “I teamed up with a representative from Ground Effects, and we focused on spacing and determining the ideal locations for each tree, considering factors like size and soil type. After that, I provided the kids with maps and instructed them, ‘Now it's time to place the trees where they belong; let’s start digging those holes.’” A representative from the DNR was present to offer a brief lesson on the advantages of trees and to assist with the planting and mulching process. Esther Eppinga, a junior, and her planting team received detailed guidelines on the appropriate depth and width for the hole designated for the ginkgo tree they were tasked with planting. “It took us thirty minutes to excavate the hole and plant the tree,” Eppinga mentioned. “The hole measured approximately 2½ feet across and was 1 foot deep. For the following weeks, I made sure to water the Royal Raindrops crabapple — we provided it with a bucket of water every other day.” The fall season was surprisingly dry, making the task of watering the newly planted trees a more challenging endeavor than anticipated. Eppinga mentioned, “The toughest aspect of the entire ordeal was when we had to transport 5-pound buckets brimming with water while making an effort to keep our clothes dry.” In addition to enhancing the aesthetic appeal of Unity Christian’s campus, the trees will also serve as valuable educational resources for Haan’s students.

Trees provide habitat for countless animals and significantly contribute to the resilience of ecosystems.” This spring, he intends to start monitoring more data points with his students. "Once the weather improves a bit, we plan to begin measuring the diameter and circumference of the trees. We'll track these measurements annually to understand growth rates and how they correlate with climate changes and drier autumns," Haan stated. He will ask his students to investigate the relationships between growth rates and various factors, such as weather patterns. Haan mentioned that he has found it easy to engage his students with the arboretum project. "They've truly embraced it and made it their own," he remarked. A proactive student decided to produce a promotional video aimed at raising awareness in the community about the arboretum project and inspiring donations of trees, possibly in memory of a cherished individual. Additionally, this year's class assigned each student, either alone or in pairs, the responsibility of caring for a specific tree. "We had plenty of trees, so I could easily assign one to each child and say, 'This one's yours to take care of' — it helps them feel a sense of responsibility for that tree." During the autumn season, Postma dedicated her time to nurturing her tree. “My tree is an Aspen Prairie Gold,” Postma mentioned. “During the fall season, I made sure to water it every Monday, Wednesday, and Friday, almost without fail.” Haan expressed his desire to plant additional trees on the school property, despite the fact that the current trees take up a significant portion of the designated space. Senior Abby Van Roekel is relishing the benefits of the project to date, which promises to transform the landscape of Unity Christian’s campus for years to come. “We invested a significant amount of time in research and planning to reach this point,” Van Roekel mentioned. “As this is my final year at Unity, I sincerely hope that the students who study earth science next year will appreciate the joy and beauty of God in the work we've initiated.”

Mysterious and Unidentified Formations Discovered Beneath the Pacific Ocean

The formations might be new or old, but scientists remain uncertain. View pictures in App save up to 80% data. Here is a representation of the locations of cooler material within the mantle, made possible by an innovative computer model. Image Credit: Sebastian Noe / ETH Zurich. Geoscientists have leveraged earthquake data to investigate the makeup of the lower section of the Earth's mantle beneath the Pacific Ocean, leading to some intriguing findings. They've identified regions where seismic waves exhibit unusual movement patterns, indicating the presence of structures that are either colder or possess a distinct composition compared to the adjacent molten rocks. The researchers characterize these structures as a significant enigma. It is unclear what these structures are. If they were anywhere else, they could be portions of tectonic plates that have sunk in a subduction zone. But the Pacific is one large plate, so there should be no subduction material under it. The researchers are also uncertain about what kind of material these deep structures are made of or what this means for the internal structure of the planet. "That's our dilemma. With the new high-resolution model, we can see such anomalies everywhere in the Earth's mantle. But we don't know exactly what they are or what material is creating the patterns we have uncovered," Thomas Schouten, first author and doctoral student at the Geological Institute of ETH Zurich, said in a statement. The existence of numerous cold areas within the mantle implies that they may have originated at various points in time and from diverse sources. These regions are not solely the result of subduction plates from the past 200 million years. Schouten elaborated, "We believe that the irregularities in the lower mantle stem from multiple sources. They might be remnants of silica-dense substances that have existed since the mantle's formation around 4 billion years ago, managing to endure the convective shifts within the mantle. Alternatively, these anomalies could represent areas where iron-laden rocks have gathered due to the mantle's movements over the span of billions of years." Further efforts are required. The team relies solely on one characteristic of seismic waves—their speed—to deduce a great deal about the processes occurring beneath our surface. Despite having impressive models, it remains a challenge to derive all necessary information from this single aspect. We cannot physically access the Earth's interior to observe its contents.   "Schouten explained, 'We need to assess the various material parameters that could account for the observed velocities of the different wave types. In essence, we must investigate the material characteristics that influence wave speed more thoroughly.'" A paper describing these findings is published in the journal Scientific Reports.

Consensus Guidelines for Histological and Clinical Reporting in HS

View pictures in App save up to 80% data. The following is a summary of “Standardized Protocols for Clinical and Histopathological Characterization of Hidradenitis Suppurativa Tissue Specimens,” published in the January 2025 issue of Dermatology by Sampath et al.  The absence of standardized protocols for the description and reporting of clinical and histological features of skin tissue samples from patients with hidradenitis suppurativa (HS) impedes consistent data collection, documentation, and communication. This is essential for advancing translational research, even in light of a recent agreement on the morphology of HS lesions.   A team of researchers carried out a retrospective analysis aimed at developing a standardized protocol for documenting the histopathological and clinical features of HS tissue samples.   A study was conducted between May 2023 and August 2023, involving specialists in clinical care, dermatopathology, and translational research. In total, 27 experts took part, comprising 14 dermatologists, 3 fellowship-trained dermatopathologists, 3 plastic surgeons, 3 general surgeons, and 4 research scientists. The researchers employed a modified Delphi technique to create a protocol aimed at histologic reporting and clinical characterization of tissue samples from patients diagnosed with HS.    The findings indicated that a total of 27 specialists were involved in the creation and assessment of protocols for the clinical and histopathological analysis of HS tissue samples. This cohort comprised 14 dermatologists (51.9%), 3 dermatopathologists with fellowship training (11.1%), 3 plastic surgeons (11.1%), 3 general surgeons (11.1%), and 4 research scientists (14.8%).   Researchers determined that the structured protocols, delivered in the form of a summary report, would promote uniform classification of HS specimens in biobanks according to their histological characteristics. This would lead to improved accuracy in reporting and the selection of samples for translational research initiatives.  You have been educated on information available until October 2023.
