Autoimmune diseases are thought to be the result of mistaken identity. Immune cells on patrol, armed and ready to defend the body against invading pathogens, mistake normal human cells for infected cells and turn their weapons on their own healthy tissues. In most cases, though, finding the source of the confusion—the tiny fragment of normal human protein that looks dangerously similar to a protein from a pathogen—has been challenging for scientists. That missing piece of the puzzle has hampered efforts to develop effective diagnostics and specific therapies for many autoimmune conditions.

That finally may be changing. A team involving researchers from Washington University School of Medicine in St. Louis, Stanford University School of Medicine and Oxford University has developed a way to find crucial protein fragments that drive autoimmunity, as well as the immune cells that respond to them. The findings, published Dec. 7 in Nature, open a promising pathway to diagnose and treat autoimmune diseases.

"Of all genes, the HLA genes have the greatest amount of variation across the . There are many, many autoimmune diseases that are associated with specific variants of the HLA genes, and in most cases we don't know why," said co-senior author Wayne M. Yokoyama, MD, the Sam J. Levin and Audrey Loew Levin Professor of Arthritis Research at Washington University. "This paper outlines a strategy for figuring out why certain HLA variants are linked to certain diseases. It also provides strong evidence that cross-reactivity between human and microbial proteins drives autoimmunity in at least two diseases and probably many others. Now that we understand the underlying drivers, we can start focusing on the approaches that are most likely to yield benefits for patients."

The autoimmune diseases ankylosing spondylitis, which involves arthritis in the spine and pelvis, and acute anterior uveitis, which is characterized by inflammation in the eye, are both strongly associated with an HLA variant called HLA-B*27. The link between ankylosing spondylitis and HLA-B*27 was discovered 50 years ago—making it one of the first such associations identified between and HLA variants—and it remains one of the strongest known associations between any disease and an HLA variant.

The HLA family of proteins is involved in helping immune cells detect invading pathogens and distinguishing between microbial and human proteins, and is highly variable across individuals. HLA proteins function like hands that pick up fragments of whichever proteins are lying about—microbial or human—and show them to called T cells to figure out if they're a sign of danger (microbial) or not (human).

T cells don't recognize protein fragments by themselves; they recognize the fragment plus the hand that holds it. Scientists have long assumed that the combination of this particular hand—HLA-B*27—plus a bit of an unknown human protein was being misidentified as dangerous in people with either of the two diseases, triggering autoimmune attacks in the eye or the spine. But for decades, they couldn't find the fragment. Some scientists began to speculate that the misidentification hypothesis was wrong and some other reason accounted for the association between HLA-B*27 and the two diseases.

Co-corresponding author K. Christopher Garcia, Ph.D., and co-first author Xinbo Yang, Ph.D., of Stanford Medicine, along with co-corresponding authors Geraldine M. Gillespie, Ph.D., and Andrew J. McMichael, Ph.D., and co-first author Lee Garner, Ph.D., of Oxford University, collaborated with Yokoyama and co-first author Michael Paley, MD, Ph.D., of Washington University on a novel way to find the elusive fragment. The research team identified certain T cells that were abundant in the blood and joints of people with ankylosing spondylitis, and in the eyes of people with uveitis.

Garcia and Yang then devised a way to identify fragments that drive a T cell response when combined with HLA-B*27, and mapped the fragments against the and five bacterial genomes to identify proteins from which the fragments may have originated. Using that approach, they were able to narrow down the millions of possibilities to a very short list of human and microbial proteins. Then, they determined the structures of the detector molecules—known as T cell receptors—on T cells from both groups of patients and compared them. The similarities were striking.

"This study reveals the power of studying T cell specificity and activity from the ground up; that is, identifying the T cells that are most active in a given response, followed by identifying what they respond to," Garcia said. "Clearly these patient-derived TCRs are seeing a spectrum of common antigens, and that may be driving the autoimmunity. Proving this in humans is very difficult, but that is our future direction and could lead to therapeutics."

The findings reveal key aspects of the biological mechanisms underlying ankylosing spondylitis, anterior uveitis and potentially many other autoimmune diseases.

"By combining recently developed technologies, we have revisited an old hypothesis that asks if the traditional antigen-presenting function of HLA-B*27 contributes to disease initiation or pathogenesis in the ankylosing spondylitis and uveitis," Gillespie said. "Our findings that T cells at the sites of pathology recognize HLA-B*27 bound to both self and microbial antigens adds a very important layer of understanding to these complex conditions that also feature strong inflammatory signatures. Our hope is that this work will one day pave the way for more targeted therapies, not only for these conditions but ultimately, for other autoimmune diseases."

By providing strong support for the idea that T cells that react to microbes also may react to normal human proteins, the findings promise to accelerate efforts to Excellerate diagnostic tools and treatments for .

"For ankylosing spondylitis, the average time between initial symptoms and real diagnosis is seven to eight years," said Paley, an assistant professor of medicine, of ophthalmology, and of pathology & immunology. "Shortening that time with improved diagnostics could make a dramatic impact on patients' lives, because treatment could be initiated earlier. As for therapeutics, if we could target these disease-causing T for elimination, we could potentially cure a patient or maybe even prevent the disease in people with the high-risk genetic variant. There's a lot of potential for clinical benefit here."

Killexams : New approach for drug and alcohol services proposed

People who have sought help for drugs and alcohol should be actively involved when developing new services according to new research from the University of Aberdeen.

A team of public experts from Aberdeen Center for Health Data Science recently published their findings on the importance of giving service-users "a voice" in the journal PLoS Global Public Health.

Working alongside partners in research organizations, services and non-profit and in South Africa, the team set out to establish new ways to Excellerate engagement and dialogue in public services—specifically around drug and alcohol programs. The 8-year-long project will look at how best to engage participants and Excellerate retainment in health improvement services.

Working with and for , the first part of the project identified alcohol and drugs as a key priority in rural South Africa and highlighted the value of involving the people who will actually use health improvement services. This approach is one that project lead, Dr. Lucia D'Ambruoso suggests would benefit all over the world including the NHS.

Dr. D'Ambruoso explains, "Whilst this project is based on work with rural communities in South Africa, alcohol and drugs serious present public health problems to our own communities and Health Service in Scotland. The lessons that we have learned from our community-led approach in South Africa are also very relevant here at home."

Dr. D'Ambruoso and her team led an initiative that created spaces for people and health systems to join together, produce research evidence, act on this evidence, and therefore learn to address common health concerns. This is contrary to approaches that may not always include the lived experience of people they are trying to help.

Dr. D'Ambruoso adds, "We took a participatory approach where we shared power throughout the : the health issues under investigation were not imposed by outsiders, but were instead directed by participants.

"We then took 'community voice' a step further—it is perfectly possible to raise community voice on local public health concerns—people are experts in their own lives after all. What is critical, and often missing, is connecting community voice to the authorities to support the establishment of virtuous cycles of 'community voice' and 'state response.'

"Marginalized community voices seldom feature in public services, however, in this project, it was possible, even in a setting of deep distrust between people and the authorities, to create spaces and processes connecting stakeholders to build dialogue, evidence, action, and learning for cooperative action on health.

"The process needed time, space and a sensitive, inclusive, informed approach shifting power and control towards those most affected and, adapting to changing circumstances and needs. The authorities embraced the process and there has been formal recognition and uptake in other settings in South Africa.

"Our experience shows that regular safe spaces can develop and align community voice with state capacity to respond—a mutual empowerment—that contributes to responses based in shared rights and responsibilities for health equity."

Dr. D'Ambruoso is also in discussions with planners and within the NHS with a view to rolling out new-participatory approaches as part of strategic plans and priorities on substance use, community empowerment and learning health systems in NHS Grampian.

John Mooney, Consultant in Public Health with NHS Grampian remarked, "Local drug and alcohol services in NHS Grampian have recently become very pro-active in exploring the most effective means of incorporating genuine lived experience into all aspects of service development and delivery.

"The work of Dr. D'Ambruoso and colleagues with very marginalized service user groups in South Africa, is therefore likely to be of great significance as we look towards fully engaging our lived experience community across our whole multi-agency network of drug and alcohol service provision."

Killexams : Using the nexus approach to identify systematic solutions for sustainable development

The United Nations Sustainable Development Goals, adopted in 2015, tackle a wide array of contemporary issues such as food, water, and energy insecurity, biodiversity loss, climate change, and rapid and spontaneous urbanization. Achieving these goals requires a strategy aimed towards overall progress, rather than improvement in isolated areas.

The nexus approach is a method for dealing with sustainable development challenges in an integrated manner considering multiple variables at once. The word "nexus" is conventionally understood to mean "link" or "connection," and the aptly named approach involves the assessment of several interconnected components. Components can be based on resource sectors, issues, or a combination of both.

The interactions between these components can be studied in a structured manner, where progress on one front might require a compromise on another (trade-off), or where two components mutually benefit from one another (synergy). Originally emerging in the early 1980s, the nexus approach has since evolved to become more complex (more components) and diverse (more distinct nexuses) and has recently garnered interest for its integrated approach to tacking global sustainability challenges.

In a recent review of the complexity and diversity of nexuses published in Science of the Total Environment, Dr. Ronald C. Estoque, a Senior Researcher from the Forestry and Forest Products Research Institute, Japan, explains how the trends of development in the nexus approach can help achieve the Sustainable Development Goals. The article was made available online on September 8, 2022 and will be published in Volume 854 of the journal on January 1, 2023.

"Examining how the complexity and diversity of nexuses have progressed over the years, especially in recent years, might provide some insights into the future direction of the nexus approach and whether such a direction is consistent with or geared towards helping to achieve global sustainability," says Dr. Estoque.

Through a of over 300 publications, Dr. Estoque found that nexuses have become more complex and diverse over time. This implies that a particular nexus now deals with many more components than included earlier. In the context of sustainability, this is advantageous, as it allows for a more fine-tuned analysis of real-world situations. Increased diversity also means that the components in different nexuses now cover a wider variety of resource sectors and issues.

While the nexus approach was introduced in the , tracing its history revealed that it was popularized in the sustainable development context much later, in recent years. The trends in the development of this approach since then have only made it more suitable for application towards meeting the Sustainable Development Goals. It is expected that, with time, several different issues and resource sectors will be linked as components to the existing nexuses, allowing better planning and management.

Currently, the nexus approach offers a platform for systems integration, with careful consideration of the interactions between different components; a platform for collaboration between scientists, , and other stakeholders; and an explorative method for prospective evaluation of potential future impacts of an intervention.

Although the nexus approach is promising, exactly which components should be included while planning for sustainable development policies remains a big question. In Dr. Estoque's own words, "Determination of the key components for, and in the context of, the global sustainability agenda is an important task, although it is certainly not an easy nor a straightforward one."

Killexams : In Ukraine, a new approach to modern conflict is emerging

I recently participated in a series of high-level conversations about how we leverage technology for strategic advantage in the face of technology-enabled threats. The gatherings, hosted by the Munich Security Conference, follows a similar talk held in Munich in February, on the eve of Putin’s invasion of Ukraine. These two conversations covered similar issues and were held less than a year apart, but the tenor and substance was dramatically different. That is because the war in Ukraine is changing how the world is responding to these threats — and Ukraine’s remarkable resilience has been both inspiring andinstructive.

In February, as we met in Munich, Russian troops were massing on Ukraine’s borders. At the time, many predicted devastating Russian cyberattacks on Ukraine’s critical infrastructure, attacks that would throw Ukraine into turmoil and accelerate what many anticipated would be their defeat. In the months since, the world has witnessed in horror Putin’s brutal invasion. But we’ve also witnessed how Ukraine has defied the skeptics, successfully defending against cyber-attacks to its critical infrastructure and making masterful use of technology in a broader way to gain the initiative.

A new approach to modern conflict is emerging along with a new way for how the transatlantic community better positions itself to leverage its technology advantage to overcome shared challenges. 

Even before the Russian invasion, technology companies had worked closely with the Ukrainian government to maintain and secure the country’s digital infrastructure. After Russia invaded, Ukrainians used smartphones and a variety of apps to share with the world — daily — the story of what was happening on the ground. They used secure communications to open supply lines and coordinate resistance to Russian efforts. Ukrainian volunteers even developed a smartphone app that allows citizens to report on the location of Russian attacks, tanks, missiles, and drones.

For Ukraine, broad access to these off-the-shelf technologies has proven crucial, allowing Ukrainians to knock the Russians off balance and fight the larger aggressor in a conflict that Putin thought would last days.

Armed with smartphones and internet access, Ukrainian civilians and NGOs have documented and shared Russian war crimes and troop positions, sometimes in real time.

Even as Kyiv was under siege, President Zelensky was able to rally his nation and galvanize the world each night with regular video messages.

Software engineers, app developers, and other tech workers in Kyiv are still going to work, fueling the country’s innovation sector. And drones, GPS devices, and other consumer products that empower secure communications have supplemented the Ukrainian arsenal.

These tools, and the ecosystem within which they are being used, represent a dynamic new addition to the old ways of doing things, and we need to think strategically about what success in this new environment looks like. More of the same is not a recipe for success. It would be a failure of creativity for us not to adapt to the changing circumstances. To build truly secure and resilient systems, we can’t just rely on government or on private sector solutions, we need both to work together.

We need to harness the expertise of the private sector and leverage our nation’s top technology leaders to out-innovate our adversaries. But this only works when all technology users — government, enterprise, and consumer — can trust that their devices, their apps, and the services they use are safe and reliable, that their data is secure, and their privacy protected.

It also means continuing to invest in the technologies that enable trust, such as cybersecurity and privacy solutions. For example, in response to the Ukraine war, companies have expanded their use of technology to protect the cloud and enable more secure communications. This has been a gamechanger for millions of Ukrainians.  

For government, the tasks are simple. We must continue to lead the world on technological innovation and build the workforce of tomorrow. At the same time, we need security baked into both products and the policymaking process. This means evaluating the security, privacy and other impacts of new policy proposals, just like policymakers perform a budgetary impact assessment before passing legislation and local leaders do an environmental impact assessment before building a new project. This “trust impact” assessment can help Excellerate outcomes and reduce the chances that policymakers will inadvertently impede our ability to harness future technologies or, worse yet, actively make devices and systems less secure, less reliable, or less resilient. 

During the Second World War, Allied forces used the BBC to communicate with the French Resistance and citizens planted victory gardens or collected scrap metal for the war effort. Today, the hidden radio and coded messages have been displaced by downloadable apps that everyone can use. Victory gardens have been replaced with citizen intelligence networks providing critical information via their smartphones or crowdsourcing for gear.  

Enabling this kind of whole-of-population effort requires ingenuity and innovation from all sectors of society. Industry, government, and every day citizens have an important role to play.

Now is not a time for a failure of creativity.

Adm. Michael Rogers, USN (ret), served simultaneously as commander of U.S. Cyber Command and director of the National Security Agency from 2014-2018.

Killexams : Personalized Approach to Alzheimer's Risk Factors Tied to Improved Cognition

SAN FRANCISCO — A multidomain intervention that includes counseling by health coaches is associated with "modest" improvements in cognition in older adults who have at least two Alzheimer's disease (AD) risk factors, results of a new pilot study suggest.

However, the control group in the National Institute on Aging (NIH)–funded SMAART study, which only received educational materials by mail, also showed improvements.

The findings suggest that "maybe this personalized approach was helpful. The effect size wasn't huge, but it was larger than most multidomain trials," study investigator Kristine Yaffe, MD, University of California, San Francisco, said in a presentation here at the 15th Clinical Trials on Alzheimer's Disease (CTAD) Conference.

Personalized Approach

The investigators launched the SMAART trial in light of research suggesting that 30% to 40% of AD risk may be preventable. Modifiable risk factors for vascular-related conditions include hypertension, low physical activity, depression, and others, Yaffe said. However, some multidomain trials "have not been positive," she added.

The new trial assessed a more personalized approach, she noted. "If you could get people to buy in, make the approach more pragmatic and personal to them, maybe you could actually move the window a little bit," Yaffe said.

Researchers recruited 172 participants aged 70–89 years (average age, 75.7 years; 63% women; 81% non-Hispanic White) via the Kaiser Permanente health plan in Washington state.

All had at least two AD risk factors, such as poorly controlled hypertension or diabetes, social isolation, or current smoking status. Inactivity was the most common risk factor. Patients with dementia were excluded.

The 90 participants in the control group received educational materials from the Alzheimer's Association every 3 months. The materials included information about reducing the risk for dementia. The other 82 participants chose one to three risk factors to focus on and worked with a trained health coach on goals. "Then we check in with them every 6 to 8 weeks or so" to determine whether the goals are being met, Yaffe noted.

The program worked with primary care physicians and focused on digital health resources, such as health apps and activity trackers.

A total of 149 participants finished the 2-year trial; 19 withdrew or were lost to follow-up, and four died.

The primary outcome was composite cognitive score. At 2 years, both groups improved in an adjusted intention-to-treat analysis: the intervention group by about 5 points, and the placebo group by nearly 3 points (average treatment effect, 0.15; sd, 0.04 – 0.26; P = .008).

"Compared to the control group and how much they changed, the intervention group got about 80% better," Yaffe said.

Asked why the control group improved so much on its own, she told Medscape Medical News that an improvement in cognitively normal adults is common. In the current study, this could be due to a placebo effect or more familiarity with the cognitive tests, she noted.

Yaffe reported that no participants experienced study-related severe adverse effects and that participants in both arms reported that they enjoyed the study.

The presentation did not address the cost of the intervention.

Risk-Reduction Strategies

Commenting for Medscape Medical News, Heather M. Snyder, PhD, vice president of medical and scientific relations at the Alzheimer's Association, said, "It is good to see this pilot study show a benefit by addressing known dementia risk factors. Approaches that use risk-reduction strategies are exciting."

However, "we need larger studies with more diverse populations so that we can be confident that risk-reduction strategies are available to and benefit all individuals and communities," Snyder said.

She added that the trial "adds to past work" that has shown that addressing risk factors such as diabetes, inadequate sleep, and lack of physical activity may benefit overall health, including cognition.

The study also "demonstrated the feasibility of conducting a lifestyle-based intervention like this through a large health system, suggesting a possible future where we identify individuals with increased risk and provide personalized risk reduction interventions, very much like we do now for heart disease," Snyder said.

The Alzheimer's Association has launched its own 2-year clinical trial, called the US Pointer Study, to evaluate the effect of lifestyle interventions in older adults at risk of cognitive decline. Results are expected to be published in 2025.

The study was funded by the National Institute on Aging. Yaffe serves on data and safety monitoring boards for the NIH, Eli Lilly, and the Dominantly Inherited Alzheimer Network trials and is on the board of directors for Alector. Snyder has reported no relevant financial relationships.

Killexams : Different role, same approach

Wide receiver Gunner Olszewski signed on with the Steelers as a former First-Team All-Pro punt returner.

Olszewski is attacking his new assignment willingly, as he does whatever else he's asked to do from week to week.

"It's nothing I've done before but I'm putting my best foot forward," Olszewski said of trying to clear paths for wide receiver Steven Sims on kickoff returns. "We're getting stuff going and I'm excited to be out there and help him any way that I can.

"Someone once told me that's what mental toughness is, doing what's best for the team when everything ain't best for you. That's the approach that I've been taking."

Olszewski also got a block on Colts cornerback Tony Brown after lining up in the left slot on third-and-goal from the 2-yard line on what became running back Benny Snell Jr.'s run for a touchdown in the fourth quarter of Monday night's 24-17 win in Indianapolis.

Olszewski's effort on Brown was highlighted by ESPN analyst Troy Aikman during an overhead replay of what Aikman maintained ended up becoming a "pretty easy walk-in" for Snell.

Olszewski celebrated as if he'd scored himself.

"Touchdowns are fun, it don't matter who gets in the box, man," Olszewski maintained. "That was cool, and that was the go-ahead score. And Benny getting the opportunity, he hadn't had much opportunities this year so I think the whole team was pulling for him. There was never a doubt in my mind he's putting the ball through that end zone.

"They called Bennie's number, no surprise there, he was hot all night. So I was just doing what I can to help him get in the end zone."

Olszewski, a 6-foot, 190-pound native of Alvin, Texas, arrived in veteran free agency as a three-year pro who had led the league in punt returns for New England in 2020 (Olszewski's All-Pro season).

He was the punt and kickoff returner when the season began on Sept. 11 in Cincinnati.

But Sims was eventually assigned both of those duties.

Olszewski lined up opposite Snell as the last line of protection in front of Sims on the kickoff return team in Indianapolis.

Olszewski also played 21 snaps on offense against the Colts (30 percent). He wasn't targeted but he ran the ball once for 9 yards.

He has three catches for 43 yards on the season and has even been a gunner on the punt team on occasion.

And he's as exited to be with the Steelers as when he first got here.

"I love being on this team," Olszewski emphasized. "I love whatever role I got. It's professional football so at the end of the day you're trying to win games. There's 'dawgs' all over the place, and sometimes you want a certain role but the role is given to someone else and they bump you somewhere else and you just try to do what you can to help the team win.

"Maybe that's a learned thing but that's something I think I've always had. So it's pretty easy for me to just adjust and play ball."

Killexams : Pangea Cyber wants to simplify security for developers with an API approach

When developers are creating a new application, they may build security features over time or take advantage of commercial offerings or open source libraries to implement certain security functions such as authentication or secrets management. Pangea Cyber wants to change that with an API-driven approach to adding security to an application, making it as easy as adding a few lines of code.

The company’s approach has attracted a fair bit of investor attention with over $50 million raised since it launched last year, an amazing amount of funding in a short amount of time, especially in the current funding environment. The latest round is a $26 million Series B.

Company co-founder and CEO Oliver Friedrichs says they decided to offer a security service for developers in the same way that Stripe offers payment services or Twilio offers communications.

“We’re calling this SPaaS. So essentially Security Platform as a Service, where we’re going to be providing dozens of different security building blocks that are all API-driven that developers can easily embed in their applications,” Friedrichs told TechCrunch.

The services start with authentication and authorization as basic building blocks, but then include more sophisticated elements like logging, scanning files for malicious activity, storing secrets and so forth.

“There’s a lot of things that applications need that are securely related. And right now they’re scattered across many open source and a fragmented list of commercial offerings. We’re looking to provide them all in one place,” he said.

There are developer-oriented pieces like Auth0 (acquired by Okta in 2021) providing authorization or HashiCorp providing secrets management, but there hasn’t been this hub of security services aimed specifically at developers, Friedrichs says.

And he believes that developer focus is what separates his company from the pack. “That’s really where this developer-first delivery model is important and unique, and it doesn’t really exist. For decades now, we have built all these traditional shrink-wrapped products for end users across the entire security industry, but we haven’t built things that are API only or API first that can be plugged in by developers,” he said.

The company already has 40 employees as it attacks this problem, and with multiple startups, including Phantom Cyber, behind him, Friedrichs has deep experience in building companies. He says, even with the economic downturn, he believes his company will thrive.

“Cybersecurity is one of those sectors that’s always resilient and always needed. While there’s a correction in valuations, we rarely see people removing cybersecurity. In fact, it continues to grow and evolve,” he said.

He says as he grows the company, diversity is a big priority for him, but even with all his experience as a founder, it remains challenging. “We focus on it deliberately across the management team and across our recruiting team. We have a full-time recruiter in-house, which is unusual for this early stage, as well as outside resources, and we have conscious conversations around it,” he said.

“Now. Is it easy? It’s not easy, right? Despite how hard you try, you can’t always meet those goals. But we are trying and I think that step number one is to make sure that that’s an objective that we do want to meet, [while understanding that] we can always do better.”

Today’s $26 million Series B investment was led by GV with participation from Decibel and Okta Ventures, along with existing investors Ballistic Ventures and SYN Ventures. The company has now raised a total of $52 million. Okta’s participation is noteworthy because, as previously noted, it acquired a developer-driven authorization piece in Auth0.

Killexams : What is Regenerative Architecture? Limits of Sustainable Design, System Thinking Approach and the Future

What is Regenerative Architecture? Limits of Sustainable Design, System Thinking Approach and the Future

A heavily cited fact within the architecture industry is that the built environment accounts for 40% of global carbon emissions. The concerning statistic puts immense responsibility on construction professionals. The idea of sustainability in architecture urgently emerged as a way of bandaging environmental damage. A wide range of sustainability practices aims no higher than making buildings “less bad”, serving as inadequate measures for current and future architecture. The problem with sustainable architecture is that it stops with ‘sustaining’.

In order to maintain the current state of the environment, the architecture community has been working towards greener means of production. Conventionally, a green building employs active or passive features as a tool for reduction and conservation. Most sustainable designs view buildings as a vessel of their own rather than integrated parts of their ecosystem. With the planet’s current needs, this approach is not enough. It is not enough to sustain the natural environment, but also restore its processes.

What is Regenerative Architecture?

In biology, regeneration refers to the ability to renew, restore or grow tissues in organisms and ecosystems in accordance with natural fluctuations. When applied to building design, this can look like structures that mimic restorative aspects found in nature. Regenerative architecture is the practice of engaging the natural world as the medium for and generator of architecture. Living systems on the site become the building blocks of the structure built in harmony with the overall ecosystem.

Regenerative architecture demands a forward-thinking approach. In contrast to sustainably designed buildings, regenerative buildings are designed and operated to reverse ecological damage and have a net-positive impact on the natural environment. Shifting from a sustainability lens to a regenerative one means that architects should question how we can design structures that not only use limited resources but also restore them. Regeneration also seeks to facilitate a more resilient environment that can resist natural challenges.

Regenerative vs. Sustainable Design

Sustainable and regenerative design may seem like different approaches - sustainability limits resource use, while regeneration replenishes them. Sustainability, however, is a subset of a larger regenerative model. Both methods overlap and incorporate similar practices, each emphasizing different green goals. Just as ‘reduce’, ‘reuse’ and ‘recycle’ can’t operate in isolation, sustainability practices lend a hand towards regenerative goals by forming the first step towards replenishing resources - limiting their consumption.

One way both practices differ is in their scale of interventions. Regenerative design demands architecture be seen as an extension of the place, the site, the flora and fauna, and the ecosystem. Buildings are treated as part of a larger system, helping to produce and share resources like clean water, energy, and food. For example, Splitterwerk and ARUP’s SolarLeaf bio-reactive façade generates renewable energy from algal biomass and solar heat. The energy generated can be used by the building, stored for future use, or provided to the utility grid.

Systems Thinking in Architecture 

When designing a regenerative environment, it is important to adopt a systems approach to thinking. All relevant and contributing entities must be considered, measuring their networks of impact on the overall ecosystem. The design must account for how a building relates to the microclimate, or how the soil can support local flora. The designed system must allow for mutually supportive relationships between entities, making sure that there is equal provide and take. Each relationship builds on the other to create a strong, thriving human-nature ecosystem.

Sustainability is all about systems and making sure we’re thinking about the entire picture so we can address a problem from all angles”, writes Nabil Nasr, the Director of the Golisano Institute for Sustainability. Rather than employing sustainable design elements as a method of greenwashing, architects must develop a deeper understanding of eco-architecture through a systems approach. Architects must move away from being mere object creators and be involved in the design of broader systems for our future. Systems thinking allows architects to recognize how the built world exists within social, environmental, and business networks, which are changing at a rate that traditional architecture must rush to support.

The Need for Regenerative Design 

The regenerative design process is fundamentally rooted in a system thinking approach. Interventions may include biomimicry to imitate nature, air-cleansing building skins, water-purifying structures, or carbon-capturing architecture. Shifting thoughts from sustainable to regenerative architecture will account for a better strategy to tackle the climate and biodiversity emergency that plagues society today. The regenerative architecture will allow the construction industry to “do good” rather than merely “less bad”.

Killexams : Online tool to support delivery of 'whole school' approach to food

The UK government, as part of the Levelling-Up agenda, has advocated that all primary schools should develop a 'whole school food policy', which outlines how a school approaches food across the entire working day to support children in making healthy food choices.

The policy paper states that should produce a statement on their website that includes their commitment to food learning within the curriculum, as well as how children and stakeholders can get involved with decisions around food culture, and how the maintains a consistently high quality food offering.

Researchers, supported by the Medical Research Council (MRC) and in partnership with the Department of Education, held several workshops with , teachers, caterers and parents, where they reported difficulties in understanding what is meant by a whole school food policy, and concerns around time pressures, , and available funds.

CONNECTS-Food

The feedback from these workshops has informed the development of a new online resource, called CONNECTS-Food, which helps schools work out how well they are already doing at implementing their whole school approach to food, as well as provides templates for school leaders to use in drafting their food policy statements, and sets out key principles that they should follow to implement their 'whole school' approach.

These principles, covering areas such as the priorities of school leaders, stakeholder engagement and pastoral care, will support schools in considering what may be feasible for them to implement in their school.

Obesity levels

Professor Maria Bryant, from the University's Department of Health Sciences, said, "Children consume a third of their food at school, providing an opportunity to promote healthy diets and reduce levels of obesity."

"It is the Government's recommendation that schools adopt an approach to food linked to activities across the whole school day, but there is enormous pressure on schools at the moment, with recovery post-pandemic, and funding issues to contend with, so expecting school leaders to do even more, means that they need extra support to understand what is required of them. "

"We hope that our online resource, which was built based on the workshops that we did with schools on this topic, will make the job of developing a food policy much quicker and easier."
