Doco Review: What Plants Talk About

This PBS documentary about the hidden life of plants opens up fundamental questions about the way we view plants through the use of beautiful videography, testimony from scientists and some not so beautiful puns. Science teaches us that like all living things, plants compete with one another for survival. But if ... Continue Reading »

Trees Breathe Easy

It looks like trees may not contribute to climate change as much as had been feared. Trees breathe out CO2 at night and, the hotter it gets, the more CO2 they release. Earlier calculations predicted that 3.4°C of warming would lead to an increase in plant respiration by as much as ... Continue Reading »

Herpes helps to control carp

European Carp are the rabbits of the inland waterways of the Murray-Darling Basin. These feral pests breed prolifically, ruin the quality of the water with silt from their digging into stream beds and out compete most native fish species. And, to date, there’s been very little that can be done ... Continue Reading »

Springing into Renewable Energy

Spring is a time for growing, refreshing, and…cleaning. With warmer temperatures, flowers, plants and trees will blossom, grow and form new leaves, and shed their winter coats. Spring is also an opportune time to talk about renewable energy, something that humans can invest in to make sure our planet continues ... Continue Reading »

Turn up the heat, dial down the power 

European research suggests that by the middle of this century the ability of electricity plants to generate power will be greatly reduced because of more frequent droughts and heatwaves. The energy generating capability for a large proportion of hydro and thermoelectric power plants will be reduced because of changes in ... Continue Reading »

As we all sat breathlessly contemplating a future that cannot be too far away, I was continually taken back to a childhood steeped ... Continue Reading »

The Beginnings of Palaeontology

Palaeontology – a word that makes me think of dinosaurs and epic scenery.

Mosquitoes, You and Climate Change

Mosquitoes are undoubtedly some of the most annoying guests at Australian barbecues. They attend only to feed on your blood, not your food.

Who was Nikola Tesla?

I’m looking at a picture of Nikola Tesla. Not the expected 30’s black and white elegance; nor really Tesla in the flesh. Rather; his death mask. It’s a yellowed coppery bust on an ugly plinth. Deposited layers of metal, one after another on a plaster substrate. I can see every line and ... Continue Reading »
