Helium lifts balloons and makes our voices squeak. But its supply on Earth is finite and is critical for modern industrial processes and medical imaging in hospitals. How worried should we be?
With artificial intelligence, machines can now examine thousands of medical images for signs of disease. Will this technology replace doctors – or work side by side with them?
From cheap prosthetic arms for landmine victims in Sudan to the promise of surgery on astronauts in space — 3D printing is sparking a healthcare revolution.

People develop a long-term problem after an episode of back pain if they expect to not recover. Steps by the medical sector to avoid catatrophising back pain by not suggesting scans will help.
Scientists and engineers have looked to nature for their inspiration for centuries. The field of biomimetics uses ideas from nature to solve complex human challenges. Synthetic biology, a more recent concept…
