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?
What does AI see in this picture?

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?
The changes in the brain from a concussion do not appear on conventional imaging tests such as CT scans or MRIs; nor are there any other tests to diagnose a concussion.
All parents should understand the symptoms of concussion, whether their child plays sports or not.
An 1883 phrenology chart.
The Victorians believed that the shape and size of the skull could reveal details about a person’s demeanour. Now it's been put to the test.
Neuroscientists require images to understand what’s happening in the brain.
Take a look at some of the amazing neuroscience images out of the Queensland Brain Institute this year.
Surgeons at the University of Saskatchewan use a 3D printed human brain to plan complex neurosurgical procedures for patients with movement disorders.
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.
Epilepsy is a chronic disorder of the brain characterised by recurrent seizures.
Epilepsy affects around 70 million people globally, 80% live in developing countries. A shortage of specialists, equipment and drugs complicates effective treatment and management.
Talking therapy or antidepressants? An MRI scan could reveal what would work for you.
Sir Peter Mansfield - even better than a rocket scientist.
University of Nottingham
While Peter Mansfield didn’t have the career as a rocket scientist he craved, his contribution to humanity has been immense.
The brain doesn’t cause lying.
A recent study suggested that the brain becomes accustomed to lying, making people merely puppets of their brains. That's too simple an explanation – and one that lets liars off the hook.
While AI seems unstoppable, our improved understanding of human brains is levelling the playing field for now.
Our language abilities are enabled by a co-ordinated network of brain regions that have evolved to give humans a sophisticated ability to communicate.
When you read this text, certain regions in your brain begin working more than others. Advanced imaging allows scientists to map the brain networks responsible for understanding language.
MRI scanners need liquid helium to cool their magnets.
Vast reserves of crucial helium have been found in Tanzania. Here's how the scientists did it.
Conduct disorder is not just teen rebellion, as some experts claim. Brain scans suggest that it's a psychiatric disorder.
The computer does more of the work than you might think.

Pairing more powerful computers with increasingly sensitive scanners can yield many benefits in medicine and other fields.
The brain processes different facial features separately, so how does it tie them together?
Different parts of our brains process different things, like the facial features, voices and the gait of people we know. But it takes memory to weave them all together into a single picture.
Traumatic events can stop the brain storing the context in which they took place.
Brain imaging study shows that we forget the context in which a traumatic event take place which could be crucial to avoiding negative loops.
Your pain is in fact produced in your head and it will produce it more readily and more intensely if you have what you think is clear evidence that something is wrong.
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.
Complex but mighty useful.
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…
While doctors still use their senses for diagnoses, they have technologies to back them up.
“Diabetic urine”, the surgeon Herbert Mayo wrote in 1832, “is almost always of a pale straw or greenish colour. Its smell is commonly faint and peculiar, sometimes resembling sweet whey or milk.” The use…
