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.
Women’s immune systems mount a significantly stronger response against invaders.
Women have evolved to have stronger immunity than men. But this comes with downsides -
women are more likely to have autoimmune diseases due to their "reactive" immune systems.
A virus like SARS can shut down cytokine production, enabling it to multiply to higher levels and causing significant infection and even death.

We've all endured infections. Here's how it works when our bodies are attacked by viruses, bacteria or parasites, and our innate immune system becomes the first line of defence.
Many suffer from heart disease despite the fact they don’t smoke, have healthy diets, and are of a healthy weight.
Many people die of heart disease who don't fit into the traditional risk factors. We're learning the immune system can be to blame.
Computers may play an important role in preparing us for the next viral outbreak – whether flu or Ebola.

This antivirus software protects health, not computers. Researchers are beginning to combat deadly infections using computer-generated antiviral proteins – a valuable tool to fight a future pandemic.
Even regular walking can drastically change your health.
Even gentle exercise can induce rapid molecular and immunological changes in your body.
In the early stage of Hodgkin’s Lymphoma the disease is curable in more than 90% of the cases.
The incidence of Hodgkin's lymphoma in Kenya isn't known, but new information is emerging to shed light on its prevalence.
The deadly facial tumour can hide itself from the Tasmanian devil’s immune system.
The facial tumour cells that threaten the Tasmanian devils may use a sort of molecular shield to protect them from the animal's immune system.
HIV plays hide and seek with the body’s immune system to evade detection. But we can learn from its tactics to make a range of vaccines against infectious diseases.
Researchers are learning how HIV hides from the immune system to develop a new generation of vaccines for seemingly unrelated diseases, like the flu.
The frustration of failed IVF cycles leads many women to seek explanations and investigate alternative options.
In pregnancy, immune cells help the uterus tolerate and nurture the embryo despite it carrying foreign genes from the father. In most women, suppressing immunity will likely cause more harm than good.
Better than pills.
The first experiment to demonstrate that an enriched environment can boost the function of some immune cells.
The science is now used to tackle a range of diseases.
Peter Doherty's Nobel Prize-winning insights proved crucial for understanding how viral infections are controlled.
