Big data points the way to custom stem cells

Genomic biologist Professor Christine Wells and biostatistician Dr Kim-Anh Le Cao are analysing big data to discover what makes stem cells tick. Already the pair have found new ways to classify stem cells, and they’re working on predicting the cells’ behaviour and even creating custom immune cells.

Christine directs Stemformatics, an online encyclopaedia of hundreds of high-quality stem cell studies from other researchers vetted and archived by Christine’s team. They’ve amassed an enormous amount of data about genetic activity in certain stem cell types at many stages of development.

To find trends across the studies, Christine called on Kim-Anh’s statistical expertise. Continue reading Big data points the way to custom stem cells

Terry Speed: fighting cancer by the numbers

Terry Speed doesn’t expect to see headlines reading “Statistician cures cancer” any time soon. But he knows that maths and stats can help researchers understand the underlying causes of cancer and reduce the need for surgery.

A mathematician and statistician, he has written elegant theoretical papers that almost no-one reads. But he has also testified in court, helped farmers and diamond miners, and given biologists statistical tools to help them cope with the genetic revolution.

Two million containers—but how many pests?

Balancing the risks and benefits of trade and pests.
Balancing the risks and benefits of trade and pests.

Every visitor to Australia quickly learns that we take quarantine seriously. Our country is free of many pests, weeds and diseases that are widespread overseas. Our relative disease-freedom is good news for our people, for agriculture and for the environment.

Visitors’ luggage is screened at the airports. But what about the two million shipping containers that enter Australia each year? How do we strike a balance between open trade and quarantine?
