The earliest hominin cancer.

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.
You are what you eat.
The world looks to the WHO for all health-related matters – but it is only part of the picture.

Bats can carry some of the deadliest diseases known to affect humans and yet they don't seem to get sick. So what can we learn from a bat's immune system?
The collapse of Syria's health system is helping spread leishmaniasis but not in the way some media outlets have reported.
Viruses are not all bad. In fact, many ecosystems would not function without them.
The word "virus" strikes terror into the hearts of most people. But most viruses are actually vital to our very existence.
Koalas are again in the firing line. But should diseased animals be culled for the greater good?
Research has shown that culling koalas could help stop the spread of deadly chlamydia. But how open will Australians be to killing one our favourite animals?
A Scottish nurse who was "cured" from Ebola is now back in serious condition after the virus appeared to have re-emerged.
BRCA1 and BRCA2 gene mutations prompted Angelina Jolie to have a preventative double mastectomy and surgery to remove both ovaries.
What if you could take a simple test to reveal your individual risk of developing a range of cancers and hundreds of other diseases?
Eradicating TB across the globe by 2035, as the World Health Organisation hopes to do, will only take place if the global funding and will improves.
More than 1.5 million people die of tuberculosis across the world every year. Although testing and screening has improved and more drugs are available, it is not enough to conquer the scourge.
Buffalo are the main wildlife carriers of Bovine TB, a disease that poses a threat not only to animals but also to humans.
People living in close proximity to animals infected with Bovine TB are at a risk of contracting the disease through drinking their milk and eating their meat.

Awareness efforts can focus public attention and help scientists raise funds for research. But the impact on eradicating the disease itself and helping patients today is much less clear.
