UP microbiologists discover rich diversity of life in Antarctica’s cold, dry soils

The ice-free areas of Antarctica were initially thought to be devoid of life, but with the advent of modern genetic technologies, scientists now know that microorganisms have adapted to living in this extreme environment.

What do microorganisms do in Antarctica's soil?

The Dry Valleys of East Antarctica are the most extreme example of polar soils; these valleys are arguably the coldest and driest deserts on Earth. In this episode, Prof Don Cowan explains why these microorganisms are important and what they do in this environment.

A day in the life of a research scientist in Antarctica

Explore this gallery to experience a day in the life of research scientists in Antarctica. Antarctica's ice mass is enormous, and melting continental ice will have dramatic effects on oceanic flow patterns and global seal levels. Antarctica is also the last “pristine” continent in that it remains largely unaffected by human activity, which is why conservation is imperative.

UP hydrogeologists use isotopes to pinpoint root of Hartbeespoort Dam’s water hyacinth problem

For years now, invasive water hyacinth plants have clogged up the North West’s Hartbeespoort Dam, which lies downstream from Pretoria and Johannesburg. In new research, hydrogeologists from the University of Pretoria (UP) have used the internal workings of the plants themselves to reiterate that the infestation is fueled by below-par sewerage works and inadequate sanitation facilities for...

A new way to name bacteria: 300-year-old system revised thanks to scientific advances

Nearly 300 years ago the Swedish botanist Carl Linnaeus secured his place in scientific history when he created what’s known as the binomial system. The year was 1737 and, due to the large diversity of plants and animals collected by naturalist explorers in different parts of the world, Linnaeus saw the need to develop a logical system to classify and group this material in a systematic way.
