The rationalization of protein hydrogel design is essential in creating bespoke and functional materials for a range of medical and healthcare applications, such as tissue engineering, wound healing and bio-sensors. The dynamic process of protein unfolding can significantly influence the resultant gel structure and behaviour - conformational changes in individual protein building blocks affect the bulk gel, whilst changes to bulk conditions influence how individual proteins move and respond.
Preparing Students to Excel in External Examinations
Success in external examinations begins with understanding the nature of the assessment. Students should know exactly what will be expected of them during the examination, including the types of tasks they will encounter, the skills they will need to demonstrate, and the structure of each section. Understanding these expectations helps students focus their preparation, minimise surprises, and build confidence.
Happy Declaration Signing Day
(Photo illustration by Bill Kuchman/The Bulwark | Photos: Creative Commons, Shutterstock) A FUNNY THING YOU MIGHT HAVE NOTICED about the semiquincentennial: Most Americans don’t know what happened 250 years ago that’s being celebrated this year. And even among those who have a general sense, there’s a lot of fuzziness about the details.
Conspiracy in the White House
What could be more presidential than Franklin D. Roosevelt’s Fireside Chats? Millions of people, threatened by economic collapse and endangered by world war, huddled around their radios to hear the avuncular FDR speak plain, reassuring words that Americans could rise together and conquer the nation’s challenges. That’s the way FDR’s leadership is remembered, anyway. Forgotten is the way Roosevelt used his radio addresses to spin conspiracy theories.
Why My AI Writing Assignment Failed
AI is here to stay, the experts say. Don’t fight it. Embrace it and give students a legitimate way to use AI in their writing. I’ve heard those claims since ChatGPT exploded onto the scene in late 2022 and sounded the death of the college essay. I’m an AI skeptic. As a historian, I know that teaching students to write and think for themselves is a crucial part of my job. But I’m also open-minded.
Love Advice from the First President Original
(Composite by Hannah Yoest / Photos: GettyImages) A QUIRK OF THE CALENDAR places Valentine’s Day and George Washington’s birthday a week apart each February, and this year’s calendar is especially quirky with the celebration of both holidays landing on the same long weekend. Presidents and love may not seem a natural combination. It’s certainly one Washington would have appreciated, though.
Turning Affordability Demand into Growth for Independent Pharmacies
Independent pharmacies have always played an outsized role in delivering care that is personal, trusted, and rooted in the community. Yet today, those same pharmacies are navigating unprecedented industry pressure—from shrinking margins and unpredictable reimbursement to rising patient cost sensitivity and increasing administrative complexity. At the same time, patients are more engaged than ever in understanding the cost of their medications.
Commentary: I miss the Gordon Rule at Florida colleges
Getting your Trinity Audio player ready... As spring classes start at UCF, I’ve removed a familiar name from my course syllabi: Jack Gordon of Gordon Rule fame. As four decades of Florida college students know, “Gordon Rule” refers to the writing intensive classes they must take as part of their general education program. Beginning this semester, however, UCF has joined other state colleges and universities in renaming the requirement. The Gordon Rule is now called the State Writing Requirement.
Sustainability and worker wellbeing: two-sides of the same coin
When thinking of sustainability, there is the tendency to think of environmental commitments – for instance, carbon neutrality targets, renewable energy, or responsible supply chains. However, these only tell part of the story. True sustainability is not only about protecting the planet, but also about organisations thriving and remaining resilient; which requires protecting the wellbeing of their people.
Psychological safety: a genuine risk to physical safety
Introduction – being safe vs feeling safe It is well recognised and understood that companies are required to safeguard their employees from physical safety risks in the workplace, whether working at height, gas leaks or fire hazards. This gives workers a sense of being safe in their place of work.
How to build positive mental health in and through work
Trigger warning: this article mentions suicide. With Suicide Prevention Day (10 September) just behind us, and with World Mental Health Day (10 October) and Men’s Health Awareness Month (November) ahead of us, now seems a really good time to stop for a moment and reflect on our own contributions to building positive mental health in and through our workplaces.

Marco Island Historical Society Upcoming Events
Marco Island Historical Society (MIHS) continues their informative and popular “Zoom In” series of virtual and in-person events with programs on the history and people of Marco Island and surrounding areas.

Safe, focused and productive: why employers should test for drugs and alcohol
Workplaces today are fast-paced and demanding, and employees face pressures that can sometimes lead to substance misuse. The impact of drugs and alcohol at work isn’t just an individual problem, it affects colleagues, workplace culture, safety and productivity. Yet, too many organisations treat it as a ‘behind-the-scenes’ issue. The truth is that employers cannot afford to ignore it. The scale of the issue Substance misuse in the workplace is more common than many realise.
Why mental health is central to driver safety
In the high-stakes world of fleet operations and driver risk management, safety professionals have long focused on vehicle roadworthiness, compliance and collision prevention. But a critical factor has often been overlooked: the mental health of the drivers themselves.
Effective stress management is about business performance not policies and support services | British Safety Council
When we talk about stress in the workplace, or psychosocial hazards, we tend to think of them through the lens of work demands, job clarity and control, relationships and team dynamics, through to support and manager styles. However, when it comes to managing stress in the workplace, many organisations still look at the issue through the lens of risk assessments and signposting to support.
Why are schools failing the stress test?
While the Government has a vested interest in cracking the stress problem to make teaching a desirable career choice again – the number of new teachers joining the profession was down by 1,400 last year and has been steadily been falling over the past decade – what about the leaders of schools and those responsible for staff wellbeing? What can they do to tackle stress in schools?
5 trends to watch in the safety sector in 2025
Wellbeing, health and safety Recent years have seen a much clearer and more widespread acceptance of the link between mental and physical health, an issue which is brought into particularly sharp focus in the sphere of health and safety, with a degree of interdependence between the two.
Get a hold on HAVS, before it’s too late | British Safety Council

The UK Hearing Conservation Association: how we work to promote the protection of the nation’s hearing health | British Safety Council
In the fast-paced (and often noisy) world of work, the preservation of hearing health is more critical than ever. Whether in construction, manufacturing, military, music or even transportation, workers in various sectors are exposed to hazardous noise levels that pose significant risks to their hearing.
5 trends to watch in the safety sector in 2025
(Click here to view article in digital edition) Few of us could imagine quite how different health and safety might look in 2025 compared to 1975, and there is little doubt that we will see similar significant shifts moving forwards. Here Dave Head, Head of Safety Marketing at Draeger Safety UK, examines some of the current and emerging trends in workplaces, and their implications for health and safety.

Capturing Dynamic Assembly of Nanoscale Proteins During Network Formation
1 Introduction Biomolecule networks and assemblies are exploited in both modern biomedical applications, from engineered cell scaffolds[1] to drug delivery systems,[2] and in processes fundamental to life, from plant cell walls[3] to tendon fibers.[4] This wide applicability is largely due to the hierarchical structures across length scales leading to a wide range of complex mechanical behaviors, including extraordinary strength and resilience and adaptation to environment change,[5-7] e.g....
This July Fourth, Remember the ‘Founding Scoundrels’
[This article was originally published on July 3, 2023.] AS AMERICANS CELEBRATING INDEPENDENCE DAY, we tend to want to remember the ideal promised by the new nation: that the United States would be a place where high-minded people led virtuous citizens in a spirit of well-ordered liberty.
A golden era of safety: 50 years of the Health and Safety at Work Act
In this issue of Safety Management, we celebrate half a century of the Health and Safety at Work Act 1974 by speaking to key people working in health and safety – from membership organisation heads to practitioners to union activists – about what it has achieved. We also look ahead to the challenges and opportunities facing the workplace in the next 50 years, and how we can build on the Act’s legacy to ensure that the health, safety and wellbeing of workers continues to improve.
Why good indoor environmental quality can enhance wellbeing
Whether it is offices, factories, schools or hospitals, the buildings where we spend our time greatly impact our health, wellbeing, performance and productivity. Indoor environmentally quality (IEQ) should be top of the list for employers, landlords and facilities managers looking to improve the buildings they are responsible for.
Recognize the Spanish contribution to American independence
May 8 was Gálvez Day in Pensacola. A celebration of Bernardo de Gálvez, commander of the Spanish force that defeated Britain at the 1781 Siege of Pensacola, it recalls the Spanish role in the American Revolution. The day, however, should be more than a local holiday. It should be recognized throughout the nation as a reminder that the American Revolution was an international war in which Americans were only a portion of the combatants.
David Head: How Spain helped free America from Britain
Yesterday was Gálvez Day in Pensacola, Florida, a celebration of Bernardo de Gálvez, commander of the Spanish force that defeated Britain at the 1781 Siege of Pensacola. The day should be recognized throughout the nation as a reminder that the American Revolution was an international war. Though Spain was not officially a U.S. ally, the two nations had a common enemy in Britain. Spain joined the war in 1779 not to help the 13 newly independent states, but to advance its own interests.

FILM FORUM: Civil War, II
Alex Garland gives us war without politics—or meaning The weekend after Russia invaded Ukraine I visited Sam’s Club with my kids. Passing the eighty-inch TVs, I marveled that a war was going on halfway around the world. In suburban Orlando, middle-aged fathers like me walked the air-conditioned aisles of big box stores. In Kyiv, they were sending their wives and children to Poland while they stayed to fight the Russians. I wondered what I would do if war came to America.
The Wilt Chamberlain Conspiracy Theory and the ‘Presentism’ Trap
AFTER MORE THAN SIXTY YEARS, the late basketball legend Wilt Chamberlain still holds the NBA record for most points in a game: 100, posted in a March 2, 1962 contest between Chamberlain’s Philadelphia Warriors and the New York Knicks. That’s 19 more points than Kobe Bryant, in second place, ever registered in a single night. It’s 31 more than Michael Jordan’s highest single-game score, and 39 more than LeBron James’s or Shaquille O’Neal’s top scores.
Burnout Britain: how can we reduce stress and put out the fire?
As the fireworks signalling the start of 2024 fizzled out, a glut of reports on workplace wellbeing pointed to a different type of burnout. One-fifth of UK workers feel burnt out, according to one piece of research released in January by human resources company HiBob, while 70 per cent of employees are planning to look for a new job this year.
Five key predictions for the safety sector in 2024
The topic of health and safety in UK workplaces begins the year in sharp focus for many businesses. With growing pressures across a range of areas, in particular, economic and environmental, budgets are tightening and sustainability goals increasingly dominate Board agendas.
How building a culture of collaboration and transparency is making powered access safer
Culture has such an important role in safety – one that often goes unrecognised. When things go wrong and accidents occur, organisations with unhealthy cultures can tend to focus on who’s to blame. But pointing the finger doesn’t help to make workplaces safer. In fact, it’s more likely to foster a negative atmosphere and create a climate that incentivises workers to cover their tracks following an incident or near miss.
2024 Outlook: We believe the market environment in 2024 will continue to support private credit, particularly as private equity activity increases
KEY POINTS 1. Within Direct Lending, we focus on lending to sponsors in non-cyclical industries such as software, insurance, and residential services, which can typically maintain cash flow levels through market cycles. 2. Companies are increasingly seeking junior capital solutions to manage interest expenses and boost cash flow. 3. We anticipate ongoing support for private credit through increased private equity activity.
Advisory Blog | 2024 Outlook: GPs who have been diligent about developing, pursuing, and executing on value creation processes have the opportunity to generate private equity returns at historical levels | Eaton Vance
KEY POINTS 1. We believe value creation through operational enhancements will be crucial to drive EBITDA and profitability. 2. The higher cost of debt is clearly a headwind for private equity (PE), but is not insurmountable. 3. In our view, companies in the middle market may be afforded a wider variety of exit opportunities . What We Are Seeing Over the past decade, private equity (PE) has performed well on the back of low interest rates and multiple expansion.
5 key predictions for the safety sector in 2024
In the meantime, safety – a topic that has taken centre stage in the last few years both during and since Covid – is not an issue that can be neglected, or compromised, in order to achieve other competing economic or environmental goals.

A REPUBLIC OF SCOUNDRELS
A fascinating look at the darker side of early American history. A rogues' gallery of conniving, treasonous men among those who shaped the early American republic. The leaders of the early republic are often portrayed as having unanimity of purpose and being comprised of the most honorable and upstanding characters.

Drug and alcohol testing in the workplace
In sectors where working environments can be hazardous and there are a variety of risks to employee safety, such as the water industry, it is vital for companies to take the issue seriously. It is therefore not surprising that increasing numbers of businesses are considering implementing drug and alcohol testing programmes.
When Historians Complain About Movies
“GET A LIFE!” THAT’S HOW RIDLEY SCOTT, out promoting his new epic Napoleon, responded to criticism of the movie’s historical accuracy.
No More Conspiracy Theories
After sixty years, JFK’s assassination still haunts us—and for good reason I used to enjoy a good conspiracy theory, especially a historical one like the Kennedy assassination. But a visit to Dealey Plaza changed my mind about both the president’s death—and the harmlessness of conspiracy theories in general. In 2006 I was in Texas doing research at the National Archives branch in Ft. Worth, and at the top of my sightseeing list was the assassination site.

How to Fix Florida’s Scholarship Program for Homeschoolers
THIS SEPTEMBER, ALL THREE OF MY KIDS are in school—at last. Following two years of pandemic homeschooling, my oldest, 9, began at a private school last year and is now in third grade. Her sister, 6, has joined her there for first grade, after kindergarten at Daddy’s Homeschool. And my little guy, 4, is enrolled in a half-day pre-K at a different private school. So far, they’re thriving—and I have some quiet mornings, at long last.
Building block aspect ratio controls assembly, architecture, and mechanics of synthetic and natural protein networks - Nature Communications
Abstract Fibrous networks constructed from high aspect ratio protein building blocks are ubiquitous in nature. Despite this ubiquity, the functional advantage of such building blocks over globular proteins is not understood. To answer this question, we engineered hydrogel network building blocks with varying numbers of protein L domains to control the aspect ratio.
