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

We now know why a meningitis outbreak in the UK in March was so severe: it was caused by bacteria that took genes from harmless microbes.

This helped the resulting bacteria evade the immune system and obtain iron from blood, boosting their growth.

An unprecedented meningitis outbreak that occurred in Kent, UK, in March seems to have been driven by a bacterial strain taking genes from harmless microbes

Listening to bursts of pink noise while you sleep seems to boost the brain's waste-clearance system.

Most other attempts to boost the flow of brain fluid are delivered while people are awake, so the sonic approach could be less disruptive, say researchers.

Came across some fascinating early research at an Alzheimer's conference last week: inhaling high levels of carbon dioxide intermittently for half an hour seems to flush proteins linked to Alzheimer’s disease out of the brain. www.newscientist.com/article/2580...

Human eggs that contain too many or too few chromosomes are a major cause of miscarriage and IVF failure.

Exciting to see that giving such eggs a single injection can substantially reduce the problem.

www.newscientist.com/article/2533...
Injection halves risk of chromosome error common in older human eggs
Egg cells missing a key protein may be more likely to end up with the wrong number of chromosomes, but an mRNA injection that helps the cells make the protein reduces the problem

Super exciting IVF breakthrough announced at the @eshre.bsky.social conference: 5 healthy lambs have been born from highly immature sheep eggs, suggesting a way to improve standard IVF, which currently relies on mature eggs.

Lambs born via IVF using highly immature eggs in major breakthrough
Lambs have been born using an experimental form of IVF that coaxes immature eggs to become mature ones. This could boost the number of eggs available for fertilisation and improve IVF success rates

CAR T-cell therapy, where immune cells are engineered to kill cancer, can do wonders for some people with the condition but it's too expensive to be available everywhere.

Now a 3D printed approach could allow more people to access it.

www.newscientist.com/article/2528...
3D-printed lymph nodes could widen access to CAR T-cell therapy
The cost of CAR T-cell therapy means that the highly effective cancer treatment is unavailable in many parts of the world. But a new way of making these cells could dramatically drive down the cost

Cancer therapy has, understandably, long focused on helping people live longer, but tumours can also be painful. Now a drug seems to both improve survival rates and relieve bone tumour-related pain, suggesting it could offer a more comfortable form of therapy.

If you're not feeling up for a social plan, you may find yourself wondering: to cancel or not to cancel? Well, it turns out that people may be more accepting of cancellations than we assume...
