Environmental science obviously floats my boat, but for sheer drama and WTF, I go to the classics: physics, cosmology and maths. If you are also so inclined, then let me recommend the podcasts of Melvyn Bragg’s In Our Time: Science radio series. These are available on the BBC Iplayer Radio ...

It is now 50 years since Apollo 11 delivered Neil Armstrong and Buzz Aldrin onto the surface of the Moon. Thinking that NASA’s Apollo program paid its way by giving us such technological marvels as non-stick frypans and pens that write in zero gravity is like thinking Richard Feynman’s greatest creation ...

Macroinvertebrates, or stream bugs, have been the focus of much debate amongst New Zealand’s freshwater science fraternity in recent times. To address declining water quality, the New Zealand government has proposed a National Objectives Framework (NOF), which includes a set of national bottom line values ...

Every day, we make decisions that affect our health and well-being. Most of these decisions are based on some understanding of science, whether we realize it or not. Should I have that extra piece of cake (biology, chemistry)? Do I have enough time to cross the road before that car ...

Reports of nitrate pollution of groundwater, with concentrations above the safe “New Zealand drinking water standard”, or World Health Organisation Guidelines, have been prominent in the media recently. This is particularly the case in Canterbury, where the Medical ...
