Scientists discover there are 10 types of breast cancer

A landmark study has revealed there are 10 different types of breast cancer, not four as previously thought - a finding that is expected to have far-reaching implications for treatment of the disease…

Genetics testing in school a success

A study offering genetic screening of year 10 and 11 students has been able to identify students at risk of a hereditary…

Gene critical to immune system

Researchers have found that a specific gene is responsible for the function of the immune system, and may be blocked or amplified…

Schizophrenia risk linked to common genetic variants

A quarter of the risk for developing schizophrenia can be traced to genetic variations that are common in the general population, a study by Queensland researchers has found. A new method of genetic analysis…

With the tweak of a gene, we could transform our looks in a few generations

The proportion of people with desirable physical traits could rapidly accelerate over a few generations with the aid of a diet that tweaks particular genes, a study suggests. Research by a team at Sydney’s…

Saving the snow leopard: stem-cell generation a bright new hope

Looking at embryonic cells allows researchers to understand many of the fundamental questions about how an animal’s genes are structured and the role they play in developing the adult animal. This information…
The demise of the woolly mammoth could teach us much about our effect on other species. George Teichmann

Did climate cause the extinction of the Ice Age megafauna?

When we think of the last 50,000 years of prehistory, particularly the “Ice Age”, extinct species such as the woolly mammoth and woolly rhinoceros often spring to mind. Did humans bring about the extinction…
