As global tensions continue to rise, the possibility of nuclear conflict develops as a real and terrifying threat. However, while much of the focus remains on immediate destruction, a new study warns of a slower, more far-reaching consequence: global agricultural collapse. A team of researchers at Penn State University have modelled how various nuclear winter scenarios could affect global production of corn to represent the expected fate of agriculture owing to soot and ultraviolet radiation during a nuclear winter.

The researchers reported that while a regional nuclear war would reduce corn production by seven per cent, a large-scale war could lead to an 80 per cent drop in annual yields. While the prediction points to catastrophic drops, the researchers urge switching to crop varieties that can grow under cooler conditions in shorter growing seasons. On the other hand, their proposed solution is to prepare agricultural resilience kits containing region- and climate-specific seeds for such crop varieties.

Flash floods, such as the one in Texas, USA, on July 4, are highly unpredictable. While there are flood prediction models and warning systems, effective flood protection requires extensive preparedness and an understanding of how people receive and act on risk information and warnings, write Keri K Stephens and Hamilton Bean. According to them, simply providing people with technical information and data is often not enough to effectively communicate the danger and prompt them to act.

To tackle this, they suggest: The key to effective emergency communication is to develop messages that resonate with specific audiences and build community networks that complement technological systems. Moreover, it can be important to apply behavioural insights to the design of every level of communication warning systems. Finally, maintaining true redundancy across multiple communication channels is an important strategy when trying to reach as many people as possible.

Europe’s commitment to becoming climate-neutral by 2050 leaves one question in mind: How can we get there in a way that’s technically feasible, economically responsible, and fair to all member states? Researchers from Aarhus University and the Technical University of Denmark offer a compelling answer.

According to their study, Europe can achieve net-zero emissions at an average cost increase of only 2.1 per cent compared to the most cost-effective scenario without self-sufficiency. This can be done through global co-ordination and solar power. Their study found that single-axis tracking systems in solar panels are cost-effective throughout Europe, proving to be most valuable in densely populated or land-constrained countries. However, they note that this is only possible if countries significantly ramp up development.

In our hyper-connected world, we rely on encrypted communications every day, whether it is to shop online, digitally sign documents or make bank transactions. However, the modern encryption systems, developed roughly 50 years ago, are more vulnerable than ever owing to the rise of cybercrime and the inability to adapt to the digital needs of today. Coupled with that is the looming threat of quantum computing that may make our encryption methods obsolete in the future. While that may be years away, there is also a growing need to boost the resilience of encryption.

To address these challenges, a research team led by Boston University is developing a physics-inspired scheme for data security and privacy called Encrypted Operator Computing. The project merges physics, computer science, and mathematics to develop scalable methods for computing directly on encrypted data, aiming to accelerate performance and make secure, privacy-preserving computing widely accessible for real-world use.

Communication has been at the forefront of all the tense developments in the past week, and it is challenging to cut through propaganda on all sides, says Amanda Coleman. According to her, poor approaches and bad behaviour are evident in crisis and emergency responses; however, after years of talking about the importance of transparency, honesty and ethical behaviour, it is more significant that this is being ignored.

She writes: With all this fog and confusion, poor behaviour and obfuscation, what can we do? If you are a communication professional, ensure that you know, own and have updated any crisis communication plans. Also, make sure that you are recognised as a strategic advisor and ensure that you have the skills and knowledge to be able to challenge approaches in the heat of the crisis. These are definitely challenging times, and finding the right way forward is important for us all.

When earthquakes and tsunamis strike in coastal communities, they leave behind massive amounts of disaster waste. This waste can severely hinder recovery efforts if not cleared quickly. A research group led by Professor Mitsuyoshi Akiyama and Koki Aoki from Waseda University, Japan, has developed a novel probabilistic framework for estimating the disaster waste disposal time in coastal communities under the combined threat of seismic and tsunami hazards.

The researchers modelled buildings, roads, and processing facilities to simulate both seismic and tsunami hazards, capturing how damage to waste disposal systems affects road network systems, or vice versa. The findings show that retrofitting bridges, adding temporary processing sites, and increasing road redundancy can dramatically improve recovery timelines. This research offers policymakers and planners a practical tool to strengthen community resilience before the next disaster hits.

During the 1990s, tech-savvy individuals were in demand; today, there is a growing demand for professionals skilled in computer espionage as the world becomes increasingly complex due to the use of artificial intelligence, note Mostafa Sayyadi and Michael Provitera. According to them, if you want to succeed today as CEO, you must review the external environment with a very keen eye toward perfection in order to help your organisation to survive.

They continue: To advance in the AI era, organisations need a systematic, integrated perspective in which all business units quickly and accurately recognise environmental changes and interact effectively with each other. This disruption also requires adopting new pillars in crisis leadership. Artificial intelligence will enable organisations to predict the future, and this will be, and already has been, a competitive advantage. The nearest goal for executives today is to embrace the clutches of artificial intelligence.

The culture of security has made significant progress from being seen as overly restrictive. However, in many cases, it is still viewed by organisations as a cost rather than an investment, notes Brian Wagner. This is where ‘Redefining Information Security’ comes in.

He continues: It aims to normalise the idea that security is an integral part of an organisation and to demystify security and make it more accessible to a wider audience. The book explains key security principles from several perspectives which, when combined, encourage action. A multifaceted approach is essential, as security is not just about implementing the latest tools and technologies. It requires a deep understanding of risk, human behaviour, and the interplay between people, processes, and technology. Exploring through these different lenses provides readers with a more holistic understanding of security and empowers them to take a more active role in protecting their organisations.

The effects of extreme weather events, such as the Texas floods, on local communities are all too evident, and the reality is that the challenge of keeping people safe has changed, along with the climate, says Anita Punwani. According to her, while lessons can, and will, be learnt in the aftermath of catastrophes, a key consideration is the question of risk financing to deal with the effects of extreme forces in a changing environment.

She continues: Traditionally, insurance has been a reliable form of risk financing in handling risks. However, communities cannot rely on insurance alone. Such events are resulting in significant uninsured losses, meaning governments at an international, national, and local level must take on greater levels of responsibilities to handle them. A long-term perspective needs to be taken in strengthening the resilience of communities and the natural environment.

How do we define how employees will be treated following a crisis, ask Rebecca Scorzato and Andrew Torres. According to them, the way the organisation treats its people during crises or disasters will ultimately influence their commitment to it and is often the reason they choose to stay, even when they have the option to leave.

They continue: There are many ways to care for employees in crisis, including a disaster relief programme. To establish a disaster relief programme, you need to secure leadership buy-in and allocate a budget. Secondly, you need to identify a great partner to help run it. The disaster relief partner company should be able to meet the demand of large-scale incidents, have the necessary infrastructure in place to cater to all of its clients' needs, and provide an easy-to-follow and user-friendly application. To achieve this, it is critical to get leadership buy-in. Understanding if this type of employee benefit programme is right for employees will need to come from the leadership team.

In 2024, it was estimated that fire and rescue services handled more than 600,000 incidents, while numbers are expected to go higher annually. This increasing scale, along with the increasing complexity of incidents, exacerbates the issue. To tackle such challenges, the Humberside Fire and Rescue Services collaborated with Unblur to implement its incident command software, IRIS Core and Tactics. The goal of the collaboration was to provide frontline crews with tools that support more consistent, accurate, and timely information sharing during incidents while allowing for faster task completion and more efficient incident resolution.

Mass fatality incidents are not distant hypotheticals; they are an ongoing and growing reality, says Lindsay Lowery. According to her, in such events, caring for the deceased often becomes a significant logistical and ethical challenge, leading to gaps in emergency response plans.

She explores a portable morgue cooling system that transforms any space into a temporary, refrigerated body storage, helping maintain professionalism and compassion during difficult situations. As emergency management continues to evolve in the midst of the climate crisis, public health emergencies, and sociopolitical instability, systems such as this are becoming a core part of preparedness planning.
