Don't try this at home, kids.

Allison and Honjo discovered how inhibiting the brakes in our immune systems can be used to treat cancer.
If they are simply too large, your tonsils can be shrunk down using special instruments which remove the valleys and crypts.
Tonsil tissue is particularly important in the first six months of life. After this, our lymph glands take over most of the work and the tonsils are essentially out of a job.
By the time they turn one, half of Australian babies have had a course of antibiotics.
There may be additional long-term health harms from antibiotic exposure in early life and before birth, including an increased risk of infection, obesity and asthma.

Fungi perform a vital role in the biological cycle, but pose an increasing danger to human health – invasive fungal infections kill three times more people than malaria.
The immune system has to establish which cells belong to us and which are foreign, no mean feat.
Nobel laureate Peter Doherty explains immunity.
The physiological changes at the onset of schizophrenia are as marked as the mental changes, new study finds.
Migrating to Europe changed the immune systems of birds who no longer needed to worry about African diseases.
Health researchers fact check the idea that running a marathon suppresses your immune system.
What’s that rash? Here’s what to look for to diagnose a common skin complaint.
Here's a list of the most common rashes and what you need to look for.
All multiple sclerosis sufferers have stem cells with the potential to heal them, but scientists are only just figuring out how to kick them into action.

Childhood adversity doesn't just affect our choices – according to new research, it also weakens the body's fundamental ability to stay healthy in old age.

Anyone who's had the flu can attest that it makes them feel horrible. But why? What is going on inside the body that brings such pain and malaise? An immunologist explains.
Scientists may have discovered why cancer incidence rises with age, and it's got more to do with the immune system than people thought.
Most people view ageing as negative. But, research shows, there's actually a lot to be positive about.
People who are chronically stressed are more than twice as likely to have a heart attack than those who aren’t.
Stress has subtle, underlying effects on almost every part of the body, including the heart, gut and immune system.
Bats are the only mammals capable of true flight. Scientists believe flight may influence their immune responses to coronoviruses, which cause fatal diseases such as SARS and MERS in humans.
Scientific studies show that bats may carry "coronoviruses" causing SARS and MERS - without showing symptoms of disease. Could the bat immune system be key to human survival in future pandemics?
Allergies may be in the genes that are passed down from parents to children.

Younus, age 9, wants to know how people become allergic to food.
A recent study of medical students and residents found they were reluctant to engage with parents who have vaccination fears. But listening to parents is important.
A recent study suggests that shunning parents who are reluctant to vaccinate their kids isn't the best strategy. A better strategy might be old-fashioned, but it works.
Parents are concerned combination vaccines, which protect against several diseases at once, can be too much for a young immune system to cope with.
Vaccines against multiple diseases in one jab strengthen kids' immune systems, not weaken them. Here's why we shouldn't fear these combination vaccines.
