Skip to content News Paleontology This exquisite Archaeopteryx fossil reveals how flight took off in birds Analyses of the fossil show never-before-seen feathers and bones from the first known bird When viewed under ultraviolet light, the soft tissues and fine skeletal details of the new Archaeopteryx specimen become visible. Delaney Drummond, ©Field Museum By Carolyn Gramling 1 hour ago An exceptionally preserved specimen of the ancient bird Archaeopteryx offers the most detailed window yet into the evolution of flight, researchers report online May 14 in Nature. The remarkable preservation of the specimen — the 14th Archaeopteryx ever unearthed — means that researchers can study aspects of the ancient bird that were previously difficult to discern, from the anatomy of its skull to the arrangement of its feathers to the soft tissues on its hands and feet.

Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. One of the most impactful stories in evolution is getting a rewrite, thanks to the exciting discovery of the earliest known set of reptile footprints. Craig A. Eury and John Eason, two amateur paleontologists exploring the fossil-rich Snowy Plains Formation in Australia, found a rock with an intriguing set of fossilized prints. They brought the intriguing specimen to professional paleontologists, who soon discovered that the roughly 356 million-year-old fossilized claw prints likely belong to an amniote–an early reptile relative.  Though small in stature, amniotes were a large evolutionary leap forward towards land-dwelling, four-limbed animals called tetrapods. The age of these prints suggest that amniotes evolved millions of years earlier than expected, according to a study published May 14 in the journal Nature.  “I’m stunned,” Per Ahlberg, a paleontologist at Uppsala University in Sweden who coordinated the study, said in a statement. “A single track-bearing slab, which one person can lift, calls into question everything we thought we knew about when modern tetrapods evolved.” When fish grew legs Tetrapods include all vertebrates with four limbs that primarily live on land, including everything from frogs to turtles to eagles, to tigers to humans. Their story began as fish left the water between 390 and 360 million years ago. Their descendants began to diversify into the ancestors of modern amphibians and amniotes–the group that includes birds, reptiles, and mammals. Originally, the timeline for how this massive diversification of life occurred was fairly clear-cut. The first tetrapods evolved roughly 390 million years ago during the Devonian period. Amniotoes and the earliest members of the modern groups of animals we see today followed fishapods during the Carboniferous period. Previously, the earliest amniote fossils dated back to  about 320 million years old to the late Carboniferous. Based on this new evidence, researchers concluded the start of the point on the evolutionary tree where the ancestors of amphibians and amniotes split actually happened in the earliest days of the Carboniferous or 356 million years ago.   Proof in the prints The newly discovered 356 million-year-old sandstone slab from this new study potentially changes this entire timeline by about 35 to 40 million years. The well-preserved footprints of long-toed feet with distinct claw impressions at the tips dot the stone and are the earliest known clawed footprints. Two sets of tracks were identified on the stone, seemingly from the same animal.  Footprints are important for paleontologists, as they can indicate the types of behaviors an extinct animal may have exhibited. The team compared the ancient tracks with a modern water monitor (Varanus salvator) lizard, since they have similarly shaped feet to what is seen on the footprints. They examined the spacing between the front and hind footprints against that living lizard’s feet. With these measurements, the team estimates that the ancient amniote may have been around 2.5 feet long, but that the exact proportions of the animal are still unknown. “Claws are present in all early amniotes, but almost never in other groups of tetrapods,” Ahlberg said. “The combination of the claw scratches and the shape of the feet suggests that the track maker was a primitive reptile.” If this new interpretation is correct, it pushes the origin of reptiles, and thus amniotes as a whole, back by roughly 40 million years to the earliest Carboniferous. A new set of fossil reptile footprints uncovered all the way across the globe in Poland are also detailed in the study and bolster the evidence. These European footprints are not as old as the ones from Australia, but are still older than previous specimens.  “The implications of this discovery for the early evolution of tetrapods are profound,” John Long, a study co-author and paleontologist at Flinders University in Australia, said. “All stem-tetrapod and stem-amniote lineages must have originated during the Devonian period – but tetrapod evolution proceeded much faster, and the Devonian tetrapod record is much less complete than we have believed.” A place on the evolutionary tree According to the team, this recalibration of the origin of reptiles has a ripple effect on the whole timeline of tetrapod evolution. Tetrapods must be older than even the earliest amniotes, since it has a deeper branching point on the evolutionary tree.  “It’s all about the relative length of different branches in the tree,” said Ahlberg. “In a family tree based on DNA data from living animals, branches will have different lengths reflecting the number of genetic changes along each branch segment. This does not depend on fossils, so it’s really helpful for studying phases of evolution with a poor fossil record.” The fossil trackways with the different tracks on it highlighted. CREDIT: Flinders University The team believes that amphibians and ammonites split apart further into the Devonian period and were likely a contemporary of the primitive, transitional “fishapod” called Tiktaalik. This evidence indicates that a diverse group of tetrapods existed when only transitional “fishapods” were believed to be dragging themselves around muddy shorelines and starting to explore the land.  If this new theory holds, it is likely that the evolution of tetrapods from aquatic creatures to those fully living on land may have occurred even faster than previously believed.   “The Australian footprint slab is about 50 cm [1.5 feet] across,” said Ahlberg, “and at present it represents the entire fossil record of tetrapods from the earliest Carboniferous of Gondwana – a gigantic supercontinent comprising Africa, South America, Antarctica, Australia and India. Who knows what else lived there?”   “The most interesting discoveries are yet to come and that there is still much to be found in the field,” added study co-author and paleontologist Grzegorz Niedźwiedzki. “These footprints from Australia are just one example of this.” 

Archaeopteryx lived about 150 million years ago during the Jurassic Period. Although the first Archaeopteryx fossil was discovered more than 160 years ago and the prehistoric bird has been well studied, an excellent specimen has yielded new information about the species, including why it could fly so well, according to a report in the journal Nature. Painstaking preparation made the “Chicago Archaeopteryx” (named because it resides in the city’s Field Museum) the best-preserved example of the species. That amount of care meant that CT scans and imaging via UV light have yielded the most vivid Archaeopteryx pictures yet. Scientists visualized its smallest bones as well as soft tissue, including some feathers.New Archaeopteryx Flight Details EmergeIllustration showing Archaeopteryx in life, including its tertial feathers that would have helped it fly. (Image Credit: Michael Rothman)Seeing Archaeopteryx in such detail revealed a long set of feathers called tertials on the its upper arm. Those feathers also place the species more accurately on the evolutionary tree among winged dinosaurs as well as a predecessor to contemporary birds, which also have tertials. “Archaeopteryx isn’t the first dinosaur to have feathers, or the first dinosaur to have ‘wings,’" Jingmai O’Connor a curator at the museum and an author of the paper, said in a press release. “But we think it’s the earliest known dinosaur that was able to use its feathers to fly.”Ancient FlightThe scientists now think they know why Archaeopteryx was such a good flier. Archaeopteryx’s upper arm bone is much longer than those of contemporary birds. That length creates a gap between the long primary feathers and others, as well as between the wings and the body. Air passing through that gap generates lift. Contemporary birds don’t need such long arms, because evolution solved their need to create lift another way: a set of tertial feathers between the bird’s body and the rest of its wing.“Our specimen is the first Archaeopteryx that was preserved and prepared in such a way that we can see its long tertial feathers,” O’Connor said in the release. “These feathers are missing in feathered dinosaurs that are closely related to birds but aren’t quite birds. Their wing feathers stop at the elbow. That tells us that these non-avian dinosaurs couldn’t fly, but Archaeopteryx could. This also adds to evidence that suggests dinosaurs evolved flight more than once — which I think is super exciting.”Other Bird Evolutionary FeaturesImaging also revealed some other key evolutionary features. For instance, seeing details of the tiny bones in the roof of its mouth are helping scientists understand how modern birds eventually developed the ability to move their beaks independent of the part of the skull that holds their brain.“That might not sound exciting, but to people who study bird evolution, it’s really important, because it’s been hypothesized that being able to evolve specialized skulls for different ecological niches might have helped birds evolve into more than 11,000 species today,” O’Connor said in the release.Also, because the scientists got a detailed look at some of the Archaeopteryx’s soft tissues they hypothesize that it may have spent a lot of time walking on the ground, and may even have climbed trees.The Chicago Archaeopteryx fossil went on display at the Field Museum in 2024. Its tiny hollow bones are embedded in a slab of limestone. At about the size of a pigeon, it is among the smallest known fossils of the species.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

Piri piri or African bird’s eye chilli peppersSteidi/Alamy Accidentally made your food too spicy? One day, you might be able to reach for an “anti-spice” condiment to tame the heat of a dish, thanks to the discovery of chemicals found in chilli peppers that counteract their spicy sensation. A chilli’s heat comes from compounds called capsaicinoids, which bind to receptors on nerve fibres within your mouth, sending impulses to the brain that create a burning sensation similar to those caused by a fire’s heat or a sting. Advertisement Chilli aficionados compare the heat of different strains using the Scoville scale, which is based on the concentration of capsaicinoids, yet some varieties aren’t quite as hot as their Scoville rating suggests they should be. To investigate, Devin Peterson at the Ohio State University and his colleagues used an analytical method known as liquid chromatography-mass spectrometry to determine how much of two capsaicinoids – capsaicin and dihydrocapsaicin – were in powdered samples of 10 types of peppers, including chile de árbol, African bird’s eye and Scotch bonnet. Then they gave samples of tomato juice containing powder from the different chillis to a panel of tasters. Each contained the same amount of capsaicin and dihydrocapsaicin – which should have been enough to give all the samples a relatively mild kick of 800 Scoville units. But the tasters perceived the heat from the 10 peppers as different, so Peterson and his colleagues performed additional chemical analyses. This identified three compounds in the chilli powder – capsianoside I, roseoside and gingerglycolipid A – that were present in high quantities in the chillies that weren’t as intense as they should have been according to the Scoville scale. All three compounds are glucosides, molecules that contain the sugar glucose. The latest science news delivered to your inbox, every day. Sign up to newsletter A group of 37 tasters then tested two samples at once, one containing these suspected spice-killing compounds and one without, placed on either side of their tongue to stop an enflamed tongue affecting a second taste test. Their feedback revealed that the compounds decreased the chilli intensity by between 0.7 and 1.2 points on a 15-point scale, on average. “They are effectively anti-spice compounds,” says Peterson. He isn’t yet sure how they work, but says they could be altering receptors on nerve fibres in the mouth in a way that results in a reduction in their burning signals. Knowing about these anti-spice chemicals could allow growers to breed or genetically modify plants so they lack them to create valuable, even hotter chillis, or breed very mild fruit with higher amounts of anti-spice, says Peterson. Using the compounds could also enable the creation of a household ingredient to tone down excessive heat in dishes, he says, or they could work as relievers for severe pain by blocking pain signals. “Sometimes when I’ve ordered food with my kids and it’s too spicy, that’s a no-go,” says Peterson. “So, the idea of having some kind of a natural compound to dial it back may be appealing.” “The way the study was done using the half tongue was very clever,” says Barry Smith at the University of London’s School of Advanced Study, adding that it shows the Scoville scale isn’t a very precise instrument for describing how hot a chilli is. Smith also wonders if the perceived intensity of menthol or mint, which cause a cooling sensation in a similar way to how capsaicinoids cause a burning one, could also be muted by these kinds of compounds.

Carrie Pallardy, Contributing ReporterMay 14, 20255 Min ReadWavebreakmedia Ltd IFE-240918 via Alamy StockJoel Klein, MD, senior vice president and CIO of University of Maryland Medical System, did not start his career in IT. He practiced as an emergency medicine physician, thriving in that chaotic and demanding environment. In the early days of electronic medical record systems, he started looking for ways to leverage data to understand performance in his hospital group. When it came time to upgrade the health system’s EMR systems, he was tapped to lead that process.  “That’s really what started accelerating that part of my career, and from there it was just one thing leading to another, and I became our CIO. I’ll have finished six years in July,” Klein shares.  He started his career in emergency medicine at North Arundel Hospital in Maryland. In 2000, that hospital joined the University of Maryland Medical System. Today, that system has 11 hospitals. As CIO, Klein has a team of 800 people, plus consultants.  He tells InformationWeek about the early days of his career, navigating the fallout of a third-party ransomware attack during COVID, and the satisfaction of being able to deliver impactful IT solutions.  From Emergency Medicine to IT Klein discovered a passion for medicine in college. He worked a series of work study jobs, one of which happened to be as a student athletic trainer. “That was my first exposure to really taking care of people,” he recalls. Related:He found his fit in emergency medicine. As he started to take on more IT responsibilities while still practicing, Klein felt himself pulled in two different directions.  “At first when I became the CIO, I didn’t want to stop seeing patients. I had done all this training. and I liked working in the ER,” he explains. Joel Klein, MDSo, he would split shifts in the ER with his colleagues. He started his day seeing patients at 5 a.m. and then went on to begin his day as CIO at 8 a.m. or 9 a.m. He worked like that through the initial years of COVID, seeing patients into 2022. But that split became unsustainable. He has a family, and the physical demands of being an ER doctor became hard to ignore.  He envisions the rest of his career in IT, but he sees ways in which his experiences in medicine and IT complement each other.  “I really don't think they’re different roles at all,” says Klein. “It’s huge variety from meeting to meeting or patient to patient. It’s the kind of variety that some people would call whiplash where you have to quickly code switch from issue to issue or stakeholder to stakeholder very, very quickly. But I’ve always loved that.” Related:A Day in the Life  Klein is still an early riser. He starts his day around 4 a.m., reading the news and catching up on email. By 7 a.m., he might be on the phone with the health system’s compliance team or its CTO. After that, he’s in the car heading to one of the system’s hospitals. Throughout the day, he will be talking to plenty of different people and teams who make a hospital run: the head of the OR, other executives, other IT workers, lab leaders.  “There are so many different walks of life and experts and professionals and therapists and clinicians and business folks in a healthcare organization, and you're responsible for their ability to do their job,” says Klein. CIOs in any industry need to be able to understand the needs of different positions and their workflows, but this can be particularly challenging in health care given the complexity and diversity of roles. “Add on the fact that you’ve got a lot of really opinionated people; doctors and nurses are not known for being shy about telling you what they think and what they need,” says Klein. “Sometimes that’s great because when you can deliver what they want, it’s really gratifying. But sometimes it feels like they’re asking for magic, and you can’t always do that given all the constraints.” Related:Resource constraints are a constant challenge, especially in an industry that is still working through the aftermath of a pandemic.  Navigating a Major Incident  Not every day for a CIO is typical. There are days, and weeks, devoted to handling the unexpected.  In December 2021, Ultimate Kronos Group was hit with a ransomware attack, impacting its customers’ payroll, staff attendance, and timekeeping capabilities.  “So, we had to stand up a way of tracking time: clock in, clock out time for 30,000 employees during the holidays, during COVID,” says Klein.  That ordeal stretched out over six weeks, a total of three pay periods. Within two weeks, IT was able to get a backup time and attendance system in place, Dr. Klein shares.  “[It meant] standing up a whole new piece of infrastructure and connecting it to the thousands of [time and attendance] clocks that we have all over Maryland,” he says. “Then, we had to convert everything back over after the third pay period when our systems came back online.” The Best Part of the Job  Much of a CIO’s role is invisible to other people in the organization. That is until something goes wrong. But there are some opportunities to bring new developments into the hospital that make it easier for people to do their jobs.  Right now, Klein’s team devoted to new technology is working on a project to place video screens in operating rooms. The screens display information on patients, current procedures, and other case details. “It’s the scoreboard and the current status of the case,” says Klein. “It can be incredibly helpful to orient people back to these fundamental safety attributes to the case you're doing. So, the feedback that we've gotten from our surgical team on that has been fantastic.” The team is currently figuring out how to bring this technology to the hundreds of operating rooms across the health system.  “You hear a need, and you engineer something, and you deliver something that just nails the need and that just makes my day when that happens,” he says.  About the AuthorCarrie PallardyContributing ReporterCarrie Pallardy is a freelance writer and editor living in Chicago.

May 13, 20256 min readDeep Math from String Theory Appears in Clashing Black HolesResearchers have shown that abstract mathematical functions from the frontiers of theoretical physics have a real-world use in modeling gravitational wavesBy Ramin Skibba edited by Lee BillingsAn illustration of two black holes about to merge and emitting copious gravitational waves. Chris Henze/NASA/SPL/Getty ImagesA decade ago astrophysicists at the Laser Interferometer Gravitational-Wave Observatory (LIGO), operated by the California Institute of Technology and the Massachusetts Institute of Technology, managed to detect subtle ripples in spacetime called gravitational waves, released by a pair of black holes spiraling into each other, for the first time. That impressive discovery—which earned the 2017 Nobel Prize in Physics—has since become commonplace, with researchers regularly detecting gravitational waves from myriad far-distant celestial sources.And as the numbers of gravitational-wave observations have increased, physicists’ careful modeling is revealing new details about their mysterious origins. Some of the most intriguing gravitational-wave events, it turns out, could arise not from catastrophic collisions but rather from near misses. Furthermore, these cosmic close calls might be best understood using concepts derived from string theory—a notional theory of everything that posits that all of nature is fundamentally composed of countless, wriggling subatomic strings. This arguably marks the first linkage to date between a core mathematical aspect of the arcane theory and real-world astrophysics.At least, that’s the conclusion of an international team of researchers that applied geometric structures inspired by particle physics and string theory to the behavior of black holes when the colossal objects closely pass and deflect each other. Such interactions between black holes or neutron stars (compact remnants of exploded massive stars) can be studied through the deflection angle, the energy released through the near miss and the momentum of the objects’ recoil—all of which may be discerned in gravitational waves. The team’s results were published in the journal Nature on Wednesday.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Black Holes as ParticlesIn their study, the researchers used an obscure class of abstract mathematical functions to solve the formidable equations involved in determining the radiated energy from a near miss. “You need these new functions, which, in math and mathematical physics, have been studied intensively but, to date, have not appeared in any real physical observable. That’s what makes it quite interesting,” says Jan Plefka, a theoretical physicist at the Humboldt University of Berlin and a co-author of the new study. Those obscure functions, known as six-dimensional Calabi-Yau manifolds, had never been shown as directly relevant to descriptions of real astrophysical phenomena before.In the years since LIGO’s initial detection, two additional major gravitational-wave observatories, Europe’s Virgo and Japan’s Kamioka Gravitational-Wave Detector (KAGRA), have come online. Together, they form the international LIGO-Virgo-KAGRA collaboration and have amassed detections of nearly 300 gravitational-wave events over the past decade, mostly from colliding pairs of black holes. Also called black hole “mergers,” such events are the cacophonous moment when these dense gravitational behemoths smash together to form a single, larger beast. Plefka and his colleagues are studying different interactions known as “scattering” events, which occur when paired black holes slip by each other, usually in prelude to their eventual coalescence. During these close encounters, the clashing gravity of the black holes causes each to accelerate past the other, generating a significant gravitational-wave signal, but the objects are sufficiently separated to avoid merging.It’s no coincidence that this resembles elementary particles deflecting each other. “You can use the techniques developed for the scattering of microscopic objects to describe this scattering of macroscopic ones,” Plefka says. Considered from far enough away, well beyond the event horizon—that pivotal region within which neither matter nor light can escape—a black hole can be modeled as a particlelike point with mass and spin, albeit one that generates gravitational rather than electromagnetic waves.On that basis, Plefka and his colleagues applied techniques from quantum field theory that are more typically used to analyze the behavior of elementary particles. “We’re building on decades of work that has been done to make predictions for collider experiments,” says Gustav Mogull, a particle physicist at Queen Mary University of London and one of Plefka’s co-authors.Closer to Complex RealitiesThe team’s goal was to bring its numerical approximations as close as possible to mirroring reality—which, of course, tends to be more messy. To do that, Mogull, Plefka and their team toiled to crank up the complexity of their calculations. In this work, the researchers incorporated five levels of that complexity—to what is known as the fifth post-Minkowskian order of precision—for describing the scattering angles of black hole pairs, their radiated energies and their recoils.This is where the Calabi-Yau geometric structures, normally associated with string theory, come in. In string theory, Calabi-Yau geometries involve the compactification of higher dimensions. Here, they are not merely abstractions but instead emerge from the researchers’ calculations of black hole scattering. It’s perhaps ironic that string theory, notoriously derided as untestable, has given rise to mathematical structures of relevance to measurable physics far from the rarefied realm of strings.A visualization of two black holes scattering off each other and emitting gravitational waves, which are rendered in shades of blue (darker shades correspond to higher energies). This visualization was computed with the aid of advanced mathematical functions known as Calabi-Yau manifolds.Mathias Driesse/Humboldt Universtität zu BerlinAny mathematical function is associated with some kind of geometry, Mogull explains—and as the function increases in complexity, so, too, does its geometry. In the case of something basic, such as the sine or cosine functions used in trigonometry, that geometry is a simple circle. Elliptic functions, on the other hand, imply a doughnut-shaped geometry called a torus, which is also a Calabi-Yau onefold. It turns out that the functions Mogull, Plefka and their team developed for black hole scattering are associated with Calabi-Yau threefold structures, which involve six-dimensional surfaces. “I don’t think the appearance of Calabi-Yaus was that unexpected within our community. I would say this represents confirmation of something that people had suspected but was yet to be verified,” Mogull says.To demonstrate the utility of their approach in their study, Plefka, Mogull and their colleagues compare their approximations of black hole scattering angles to other, presumably more precise ones that were derived from numerical simulations. Such simulations can be time-consuming to run, even on state-of-the-art supercomputers—hence the search for accurate approximations. The team’s highest-order approximation closely matches the results of supercomputer number crunching for cases of black holes that gently deflect each other across great distances. But when the black holes come closer to a head-on collision, the team’s calculations begin diverging from the numerical simulations.Such work may seem to be a purely academic exercise, but in fact, the research could prove vital for making new discoveries. Signals from scattering black holes and neutron stars should be within reach of the next generation of gravitational-wave detectors that are set to come online in the late 2030s. These detectors, which will also need a new generation of models called waveform templates to discern true gravitational-wave signals from a sea of cosmic and terrestrial noise, include the proposed Einstein Telescope in Europe and Cosmic Explorer in the U.S. The latter, like LIGO, is supported by the National Science Foundation, and so far these kinds of gravitational-wave projects have avoided being directly targeted by the Trump administration’s aggressive proposed cuts to federally funded science.The work’s prospect for enhancing our understanding of gravitational-wave sources excites scientists who are gearing up for this new wave of detectors. They include Jocelyn Read, a physicist at California State University, Fullerton, who works with the Cosmic Explorer project. “Next-generation facilities can measure nearby signals with exquisite fidelity,” she says. (Here “nearby” means “within a few billion light-years.”) “So having very accurate and precise predictions from our current theories is definitely needed to test them against those kinds of future observations,” Read adds.Yet she also urges caution when assessing the significance of Plefka, Mogull and their colleagues’ work. “If they’re talking about implications for gravitational-wave astronomy, there are a few more steps that are needed,” she says. And their team has competitors, too, including some who have been deploying numerical simulations of their own.These kinds of approximate methods could eventually inform the waveform templates that are so crucial for filtering out noise in upcoming gravitational-wave detectors, Plefka says. Geraint Pratten, a LIGO physicist at the University of Birmingham in England, agrees. “I think it’s a heroic calculation by the group. It will provide a lot of insight into how we can structure next-generation waveform models,” he says. Pratten adds that more work will need to be done to move past the new study’s limitations. For example, the paper focuses on black holes without spin and those that undergo “unbound” scattering, which means that they deflect each other and never meet again. In reality, most, if not all, black holes are thought to spin, and usually scattering events precede an eventual merger.But in any case, he believes some gravitational waves from black hole and neutron star deflections will eventually be detectable, such as through observations of globular clusters, where these dense objects are packed together in a small space, cosmically speaking.For Plefka, Mogull and their peers, this macroscopic version of quantum field theory is still a young field, and there are many new types of astrophysically relevant calculations that they and others can do. These esoteric Calabi-Yau structures, formerly on the frontier of theoretical physics, could be just the beginning. “You’ve had this whole new class of mathematical functions—these theoretical things that had appeared in string theory,” Mogull says. “And we’re saying, ‘Look, this is tangible. This [radiated energy from scattering] is something you can try to detect, try to measure. This is real physics now.’”

Source: Wright & Wright ArchitectsProposed scheme on Oxford High Street Wright & Wright Architects have secured planning permission for a major retrofit scheme for All Souls College, Oxford. The project is intended to create new academic and public-facing spaces within a group of conjoined historic buildings on Oxford’s High Street, expanding the college’s presence beyond its historic quadrangles. The scheme is intended to restore original architectural features across a series of existing buildings and shoprfronts, while introducing new facilities across multiple floors. The upper levels will include three seminar rooms, a lecture theatre with capacity for 100 people, fellows’ studies, staff offices and a rooftop garden. Historic elements such as 17th-century stone walls, ancient roof timbers and 18th-century ceilings are to be retained and revealed as part of the works. Clare Wright, founding partner at Wright & Wright, said: “It has been a privilege to help realise the College’s ambition to remodel an extraordinary set of historic buildings on an important site on Oxford’s High Street. In an era when city centres are languishing, this pioneering project can help preserve the soul of Oxford.” David Renton, estates bursar at All Souls College, said: “Our ambition is to create a place of learning that connects directly with the life of the city, while honouring the historic complexity of the site.

The project, comprising three conjoined structures, is described by the architects as a low-energy, deep retrofit. The design aims to reduce carbon emissions while safeguarding the building’s historic fabric. Later modern interventions are to be stripped out in order to improve environmental performance and expose earlier features.

Carrie Pallardy, Contributing ReporterMay 14, 20255 Min ReadWavebreakmedia Ltd IFE-240918 via Alamy StockJoel Klein, MD, senior vice president and CIO of University of Maryland Medical System, did not start his career in IT. He practiced as an emergency medicine physician, thriving in that chaotic and demanding environment. In the early days of electronic medical record systems, he started looking for ways to leverage data to understand performance in his hospital group. When it came time to upgrade the health system’s EMR systems, he was tapped to lead that process.  “That’s really what started accelerating that part of my career, and from there it was just one thing leading to another, and I became our CIO. I’ll have finished six years in July,” Klein shares.  He started his career in emergency medicine at North Arundel Hospital in Maryland. In 2000, that hospital joined the University of Maryland Medical System. Today, that system has 11 hospitals. As CIO, Klein has a team of 800 people, plus consultants.  He tells InformationWeek about the early days of his career, navigating the fallout of a third-party ransomware attack during COVID, and the satisfaction of being able to deliver impactful IT solutions.  From Emergency Medicine to IT Klein discovered a passion for medicine in college. He worked a series of work study jobs, one of which happened to be as a student athletic trainer. “That was my first exposure to really taking care of people,” he recalls. Related:He found his fit in emergency medicine. As he started to take on more IT responsibilities while still practicing, Klein felt himself pulled in two different directions.  “At first when I became the CIO, I didn’t want to stop seeing patients. I had done all this training. and I liked working in the ER,” he explains. Joel Klein, MDSo, he would split shifts in the ER with his colleagues. He started his day seeing patients at 5 a.m. and then went on to begin his day as CIO at 8 a.m. or 9 a.m. He worked like that through the initial years of COVID, seeing patients into 2022. But that split became unsustainable. He has a family, and the physical demands of being an ER doctor became hard to ignore.  He envisions the rest of his career in IT, but he sees ways in which his experiences in medicine and IT complement each other.  “I really don't think they’re different roles at all,” says Klein. “It’s huge variety from meeting to meeting or patient to patient. It’s the kind of variety that some people would call whiplash where you have to quickly code switch from issue to issue or stakeholder to stakeholder very, very quickly. But I’ve always loved that.” Related:A Day in the Life  Klein is still an early riser. He starts his day around 4 a.m., reading the news and catching up on email. By 7 a.m., he might be on the phone with the health system’s compliance team or its CTO. After that, he’s in the car heading to one of the system’s hospitals. Throughout the day, he will be talking to plenty of different people and teams who make a hospital run: the head of the OR, other executives, other IT workers, lab leaders.  “There are so many different walks of life and experts and professionals and therapists and clinicians and business folks in a healthcare organization, and you're responsible for their ability to do their job,” says Klein. CIOs in any industry need to be able to understand the needs of different positions and their workflows, but this can be particularly challenging in health care given the complexity and diversity of roles. “Add on the fact that you’ve got a lot of really opinionated people; doctors and nurses are not known for being shy about telling you what they think and what they need,” says Klein. “Sometimes that’s great because when you can deliver what they want, it’s really gratifying. But sometimes it feels like they’re asking for magic, and you can’t always do that given all the constraints.” Related:Resource constraints are a constant challenge, especially in an industry that is still working through the aftermath of a pandemic.  Navigating a Major Incident  Not every day for a CIO is typical. There are days, and weeks, devoted to handling the unexpected.  In December 2021, Ultimate Kronos Group was hit with a ransomware attack, impacting its customers’ payroll, staff attendance, and timekeeping capabilities.  “So, we had to stand up a way of tracking time: clock in, clock out time for 30,000 employees during the holidays, during COVID,” says Klein.  That ordeal stretched out over six weeks, a total of three pay periods. Within two weeks, IT was able to get a backup time and attendance system in place, Dr. Klein shares.  “[It meant] standing up a whole new piece of infrastructure and connecting it to the thousands of [time and attendance] clocks that we have all over Maryland,” he says. “Then, we had to convert everything back over after the third pay period when our systems came back online.” The Best Part of the Job  Much of a CIO’s role is invisible to other people in the organization. That is until something goes wrong. But there are some opportunities to bring new developments into the hospital that make it easier for people to do their jobs.  Right now, Klein’s team devoted to new technology is working on a project to place video screens in operating rooms. The screens display information on patients, current procedures, and other case details. “It’s the scoreboard and the current status of the case,” says Klein. “It can be incredibly helpful to orient people back to these fundamental safety attributes to the case you're doing. So, the feedback that we've gotten from our surgical team on that has been fantastic.” The team is currently figuring out how to bring this technology to the hundreds of operating rooms across the health system.  “You hear a need, and you engineer something, and you deliver something that just nails the need and that just makes my day when that happens,” he says.  About the AuthorCarrie PallardyContributing ReporterCarrie Pallardy is a freelance writer and editor living in Chicago.

Grandmillennial aesthetics, draped curtains, canopy beds, warm minimalism—these are some of the bedroom trends that designers predicted (and still are expecting to see) for 2025. They center around warmth, coziness, and personality, providing a much different experience than the picture-perfect clean minimalism bedrooms of Pinterest eras past. And the visually-fueled social media platform is seeing that too, predicting that the inviting and informal interior trend of "bedscaping" is about to take the world by storm.As stark white interiors have fallen out of style and more maximalist looks have moved into the spotlight, Pinterest has found that certain terms that support these personality-filled rooms are seriously gaining momentum. The term "eclectic apartment" has jumped by 630 percent, and the search term "boho bedroom" is up by 65 percent as people embrace the curated mess aesthetic and aim to create something bolder with more character through their decor. "Ten years ago, bedscapes tended to be very minimal, often embracing a white-on-white aesthetic that, while clean, could feel slightly impersonal," Eleanor Trepte of Dekay & Tate Interiors says. When the COVID-19 pandemic happened, more people spent extended time at home than they had in years, leading to a greater focus on comfort. "Since then, bedscaping has become far more personal, with layered bedding, mood lighting, and bolder colors and patterns taking center stage."If you're looking for fresh ways to make your bedroom feel cozier this spring and summer, keep reading for tips on how to bedscape the designer-approved way. Related StoriesFocus on TextureMatthew NiemannDifferently textured upholstery, draperies, and fabrics give this bedroom by Galeana Younger drama and boldness."I think bedscaping is less about decorative frills and more about texture and layers," says designer Amy McCoy of McCoy Design Studio. She explains that her clients want textures that feel more cozy and soft rather than starchy. It's those softer textiles on the bed that invite you to relax. Designer Autumn Pochiro of Autumn Dawn Design adds that neuroaesthetics, the scientific study of how we react to creative works, "tells us that bedroom color, lighting temperature, pattern, and texture all play a part in how we unwind to fall asleep." A bed that's made with an enveloping material like cotton sateen, a heavy down duvet, and ultra-plush pillows can encourage better sleep after a long day.Layer AwayCourtesy of Autumn Dawn DesignA mountain of pillows and a textured, patterned knit blanket rest on top of another bold patterned duvet in this colorful bedroom by Autumn Dawn Designs.As Trepte puts it: "The perfect bedscape is all about layering to create an inviting, restful environment." Layering different patterns and textures adds personality and visual interest to your bedroom, and it can be done in simple ways if you prefer a more minimalist style. Trepte likes layering crisp white linens with warm quilts or throws and patterned pillows for personality. For a step-by-step guide on how to layer your bed, Pochiro explains that the first layer is sheets, then something plush, like a goose-down duvet or comforter. Next comes the decorative accents—your throw pillows and shams—and finally, a bed scarf at the bottom of the bed. Opt for Mood LightingBrie WilliamsA custom lampshade and golden sconce add more accent lighting to this bedroom by Heidi Woodman. A perfectly bedscaped bedroom does not go hand-in-hand with bright overhead lighting. Ambient lighting from lamps, sconces, and dimmers is key to creating a cozy bedroom environment. If you do need overhead lighting for whatever reason, Trepte suggests adding warm-toned lightbulbs that'll give the space a more luxurious vibe. Finish with a FragranceManu RodríguezDesigner Rayman Boozer displayed a bright burst of orange roses on this bedside table, adding a nice pop of color and a fragrant scent.After everything is visually the way you want it, the final step to bedscaping is finishing off with your favorite scent. Whether that's from a candle, a room or linen spray, incense, or a plug-in diffuser, this is the cherry on top of creating a space that's comforting and uniquely yours, explains Trepte.
