What does dementia feel like?
Activists form a red ribbon, the symbol of the worldwide campaign against AIDS in Russia, 2010.
In Russia, social networks have given a new life to the conspiracy theory that HIV-AIDS is a global hoax.
Studies show wifi, mobile phones and other sources of electromagnetic radiation don’t make us sick. So, why are some people convinced they’re electrosensitive?
Studies suggest electrosensitivity is a "communicated" disease, spread by people hearing about the alleged dangers, and sometimes worrying themselves sick.
DNA holds the secrets of human existence, and studying rare diseases can reveal some of these facts of life.
Rare diseases may only affect a handful of people but their treatment benefits everyone.
Genomes can reveal a lot about disease risk. But people need to think carefully about what they want to know.

Lettuce leaves and purgatives might ease your aching heart.
Bacteria are single-celled organisms but you'd be fooled to think they weren't also hugely complex.
We shouldn't scoff at the Facebook founder's goal of eradicating disease.
Huge swathes of Tasmania have burned this year.

A comprehensive analysis of Tasmania's natural disaster risks has identified bushfire as the biggest threat, alongside emerging issues such as disease epidemics and heatwaves.
It is an illness that runs in families – but there are other factors which go beyond inheritance.
The earliest hominin cancer.
Patrick Randolph-Quinney (University of Central Lancashire/University of the Witwatersrand)
Cancer is not the modern disease many believe it to be. New fossil evidence from two South African caves suggests that its origins lie deep in prehistory.
We’ve long heard we can’t blame people for their addiction because it’s a disease, but is it?
Some think labelling it a disease is a helpful way to think about addiction; others think this makes the addict helpless in their fight against addiction. Two academics debate both sides of the coin.
What could we do if a real-life zombie disease started to spread?
Dictyostelium discoideum at work.
They may be single-celled organisms, but as our distant cousins amoeba can tell us a lot about ourselves.
Clean water can help to break the link between poor hygiene and eye diseases such as trachoma.

As Australia joins a New York summit to discuss the UN Sustainable Development Goals, it still faces questions over whether it is meeting water standards at home.
Suffering in silence.
Recognising the symptoms of the dispossessed will prevent crimes against humanity.
The silverlead whitefly is a major agricultural pest.
Invasive species and diseases pose a major threat to agriculture – particularly in the countries that can least afford it.
Computer modelling can help in the fight against the spread of disease.
It took a computer to discover the potential threat of a drug-resistant strain of swine flu that was about to spread from New South Wales. So how close did we come to a global pandemic?
Advances in computing make it possible to model the spread of disease on an individual level, in a population of millions of people.
Millions of people die or suffer from infectious diseases each year. Computer modelling can now help simulate the impact of any spreading disease.
Apartheid sought to divide blacks and whites in all spheres of life.
The rhetoric of racial purity is full of suggestive terms like illness, weakening and dilution. These imply the medicalisation of the nation.
