Our bodies contain a ghostly web of thread-like vessels and bean-shaped nodes, called the lymphatic system.

My latest cover story looks at how it could be a secret ingredient in treating some major health conditions from Alzheimer's disease to cancer.

The extraordinary influence of the lymphatic system on our health
It has remained mysterious for millennia, but we’re finally uncovering the profound role the lymphatic system plays in everything from preventing dementia to fighting cancer

Pulsing ultrasound waves through the brain seems to help clear dead blood cells from the organ after a type of stroke, improving survival.

The approach could potentially help to clear toxic proteins linked to brain conditions like Alzheimer's disease.

Ultrasound may boost survival after a stroke by clearing brain debris
The damage of strokes caused by brain bleeds can be mitigated by removing dead blood cells. Scientists have now found a way of doing this non-invasively, with promising results in mice

A magnetic tool for removing kidney stones that's "sort of like using a stick to fish out a snot full of stone fragments" could mean fewer surgeries, and less pain, for people with the condition.

Magnetic gel could remove kidney stones more effectively
Standard techniques for removing kidney stones often require repeated surgery, but a magnetic gel seems to make the process more efficient

It can be hard to focus after a bad night's sleep...Now we may know why. It turns out that momentary lapses in attention may occur because the brain's trying to catch up with clearing out waste - something it usually does while we snooze.

Can't focus after a bad night's sleep? Your dirty brain is to blame
During sleep, your brain cleans itself by flushing through cerebrospinal fluid to prevent damage to brain cells. If you're lacking in sleep, this happens when you are awake – and seems to cause moment...

Some of our immune cells fend off infections by undergoing an inflammatory form of cell death, but this may come at the cost of chronic inflammation later in life.

Good immune health may come at the expense of chronic inflammation
Inflammation is a vital part of the immune response, but it seems that the system can sometimes go awry, resulting in chronic inflammation that has been linked to conditions such as cancer
