The coming technology will make the current technology which we have right now look like child’s play. Science is pushing the boundaries of what’s possible, tackling humanity’s most pressing challenges. From AI revolutionising scientific discovery to breakthroughs in organ transplantation these innovations promise to reshape our lives. Let’s explore the top 10 technologies that could define our future uncovering their potential and the ethical dilemmas they present.
10. Genomics for Transplants: A Pig’s Heart in a Human Chest
In January 2024, David Bennett Sr. became the first human to receive a genetically modified pig heart. This breakthrough in xenotransplantation offers hope to over 100000 Americans on organ transplant waiting lists. By genetically modifying pig organs to be more compatible with human bodies scientists aim to create an unlimited supply of transplantable organs. However this technology faces ethical concerns from animal rights activists and risks of zoonotic diseases. Despite these challenges, the potential to save countless lives is enormous but it raises profound questions about the boundaries between human and animal.
9. Alternative Livestock Feeds: From Waste to Nourishment
With global population growth straining food systems scientists are turning to unexpected sources for livestock feed. Globally we produce over 1.3 billion tons of food waste annually. Repurposing this waste could address both food scarcity and waste management. One approach uses black soldier fly larvae to break down food waste. These protein-rich insects can be processed into animal feed. In trials chickens fed insect-based diets showed comparable growth rates to those on conventional feeds. Another innovative source is single-cell proteins from bacteria, yeast or algae. These microorganisms can be grown on industrial byproducts turning waste into valuable nutrients. Challenges include scaling up production, ensuring consistent quality and navigating regulatory hurdles. Consumer acceptance of meat from animals fed these novel diets remains uncertain. However these alternatives offer a path toward more sustainable animal agriculture.
8. Carbon-Capturing Microbes
Engineered microbes are emerging as unlikely heroes in the battle against climate change. Scientists have modified certain bacteria and algae to consume CO2 more efficiently, converting it into useful products like biofuels or biodegradable plastics. One such microbe Caucus elongatus has been engineered to produce ethanol from CO2 with efficiency surpassing many plants. At scale these microbes could potentially sequester gigatons of CO2 annually significantly mitigating greenhouse gas emissions. However, ensuring the stability and safety of these engineered organisms in open environments is crucial. Concerns about potential ecological disruptions and the energy requirements for maintaining optimal conditions at an industrial scale present significant hurdles.
7. Elastocaloric: The Cool New Way to Heat and Cool
Elastocaloric materials could revolutionise how we heat and cool our world. When stretched or compressed these materials change temperature. Upon release they return to their original temperature, absorbing heat in the process. Elastocaloric systems could be 20 to 30% more efficient than traditional vapour compression systems used in most refrigerators and air conditioners. Given that cooling accounts for about 10% of global electricity consumption, this improvement is significant. Moreover these systems don’t require harmful refrigerants like hydrofluorocarbons (HFCs) which are potent greenhouse gases. However, current elastocaloric materials, often nickel-titanium alloys, are expensive and can degrade over time. Scientists are exploring more abundant and eco-friendly options like natural rubber but these are still in early stages of development.
6. Immersive Technology for the Built World
Immersive technology is blurring the line between digital and physical worlds changing how we design, construct and interact with our surroundings. Cities like Helsinki are using digital twins to simulate and optimise everything from traffic flow to energy consumption allowing planners to test scenarios before implementing changes. In construction augmented reality (AR) is revolutionising building processes. Workers can use AR glasses to see 3D blueprints overlaid on physical space, reducing errors by up to 90%, according to one study. However this technology raises privacy concerns as our built environments become more connected and data-driven. There’s also the risk of deepening the digital divide as access to these technologies may not be equitable.
5. Integrated Sensing and Communication (ISAC)
ISAC technology could turn our wireless infrastructure into a vast sensing system. ISAC uses radio waves not just to transmit data but also to gather information about the environment, creating detailed maps of surroundings, detecting movement and even monitoring air quality. Applications range from real-time traffic monitoring in smart cities to non-invasive patient monitoring in healthcare. For autonomous vehicles it could offer an additional layer of environmental awareness. Early tests suggest ISAC could increase network capacity by up to 50%. However it raises significant privacy concerns, as a system that can detect movement through walls could easily be misused for surveillance.
4. High-Altitude Platform Stations: Bringing the Internet to New Heights
High-altitude platform stations (HAPS) are essentially flying cell towers operating at altitudes of about 20 km. They aim to provide internet connectivity to areas where traditional infrastructure is impractical or impossible. As of 2023 over 2.6 billion people in 100 countries still lack internet access. HAPS could change that, bringing educational resources, telemedicine and economic opportunities to previously unconnected communities. HAPS can be deployed quickly in response to natural disasters restoring communication when it’s needed most. They are also more cost-effective than building traditional cell towers in sparsely populated areas. However, keeping these platforms aloft for extended periods requires advanced materials and energy systems. Navigating complex international airspace regulations and addressing potential environmental impacts are ongoing challenges.
3. Reconfigurable Intelligent Surfaces (RIS)
Reconfigurable intelligent surfaces (RIS) are smart panels that can dynamically alter their electromagnetic properties redirecting signals to areas with poor coverage enhancing signal strength or creating interference-free zones. Early studies suggest RIS could increase network capacity by up to 10 times while significantly reducing energy consumption. In dense urban environments RIS could dramatically improve connectivity without additional base stations. Beyond improving phone signals, RIS could enable precise indoor positioning, accurate to within a centimetre, revolutionising industries from healthcare to manufacturing. However creating surfaces that can effectively manipulate signals across a wide range of frequencies is technically complex and potentially expensive. Privacy concerns have also been raised as the ability to precisely control wireless signals could potentially be used for targeted surveillance.
2. Privacy-Enhancing Technologies (PETs)
Privacy-enhancing technologies (PETs) are designed to protect personal information in our data-driven world. They include advanced encryption methods and synthetic data generation. Homomorphic encryption allows computations on encrypted data without decrypting it first, potentially revolutionising fields like healthcare by enabling the analysis of sensitive medical data without compromising patient privacy. Federated learning allows AI models to be trained on distributed data sets without centralising data. Already used by companies like Google to improve keyboard predictions without accessing users’ personal messages, PETs could enable new forms of collaboration and data sharing unlocking previously inaccessible insights due to privacy concerns. However many of these technologies are computationally intensive, potentially slowing down systems or increasing costs.
1. AI for Scientific Discovery: Unleashing the Power of Machine Minds
AI is fundamentally changing how we explore and understand our world. In drug discovery the first AI-designed drug entered human clinical trials in 2023 developed in just 12 months at a fraction of the usual cost. This could open up possibilities for treating rare diseases previously considered economically unfeasible. In material science AI is predicting properties of new compounds before they’re synthesised. One AI system recently identified a new material for more efficient solar cells potentially accelerating our transition to renewable energy. Even in theoretical physics, AI is making breakthroughs. In 2023 an AI model solved a decades-old problem in nuclear fusion, identifying optimal magnetic field configurations overlooked by human scientists. AI can identify patterns in vast datasets impossible for human researchers to spot leading to new hypotheses across fields from astronomy to neuroscience. However concerns about the black-box nature of some AI systems raise questions about reproducibility and scientific understanding. There’s also a risk of AI perpetuating biases present in training data potentially skewing research. Ensuring equitable access to these technologies is crucial to prevent a scientific divide between those with and without access to advanced AI systems.
As we venture into this AI-driven scientific frontier, we must balance the immense potential with careful consideration of its implications. These top 10 technologies of 2024 promise to reshape our world but their true impact will depend on how we choose to develop and apply them.
