Deep dives
The Role of AI in Healthcare
Artificial intelligence (AI) is increasingly being integrated into healthcare systems, particularly the NHS, to enhance diagnostic capabilities and improve patient outcomes. Recent studies indicate that AI tools, specifically deep learning networks, have shown considerable promise in breast cancer screening, allowing radiologists to more accurately detect conditions while reducing unnecessary patient recalls for further tests. However, there are limitations to AI in clinical environments, as some studies reveal that AI’s effectiveness diminishes in nuanced human interactions, leading to poor diagnostic accuracy during patient conversations. The journey towards widespread adoption of AI in medicine is expected to accelerate, but trust and ethical considerations remain paramount as the technology evolves.
AI’s Limitations and Patient Interaction
Research indicates that while AI models can excel in structured scenarios, they struggle with the complexities of real patient interactions, revealing significant challenges in their diagnostic capabilities. For instance, AI chatbots trained on large datasets perform poorly when faced with nuanced questions that characterize genuine human-to-human interactions, often leading to inaccurate diagnoses. Additionally, the emergence of AI systems that can simulate empathy has shown that some patients prefer interacting with AI over human clinicians, particularly when time is limited. This raises critical ethical concerns about reliance on AI and the necessity for robust checks to ensure the accuracy and trustworthiness of AI-assisted diagnoses in clinical settings.
The Impact of Climate Change on Natural Disasters
The Santa Ana winds in Southern California, known for their intensity and ability to exacerbate wildfires, are influenced by various climate factors, including high-pressure systems over dry regions. These winds, which can reach up to 80 miles per hour, create challenging conditions for firefighting efforts and contribute to shifting fire seasons due to climate change. Climate scientists have observed that while the winds themselves are a natural occurrence, the changing patterns and increased frequency of fires are linked to broader climatic shifts. This interplay stresses the need for heightened awareness and preparedness regarding natural disasters as the landscape of climate continues to evolve.
Artificial intelligence is the big talking point of the week, with UK PM Sir Keir Starmer announcing a drive to unleash its full potential.
It’s already being used in healthcare, but recent studies have exposed both strengths and weaknesses.
We’re joined by Dr James Kinross, a surgeon and researcher at Imperial College London, to discuss the positives and the pitfalls.
Also this week, we talk all about what a Trump presidency might mean for science; why powerful winds are driving the deadly fires in LA – and anyone for science-optimised pasta? Marnie is helped by a physicist to make the perfect Cacio e Pepe.
Spoiler alert: Recipe below!

Science-backed Cacio e Pepe:
For two servings:
- 240 g pasta
- Black pepper
- 160 g pecorino cheese
- 4g corn starch in 40ml water
Dissolve the corn starch in water and heat until it forms a gel. Let this cool before combining it with the cheese and black pepper. Cook the pasta, then drain, keeping some of the water. Let it cool then mix the pasta with the sauce. Enjoy!
