Mopping up gases

Deanna D’Alessandro University of Sydney A sponge that filters hot air and captures carbon dioxide We need better ways of capturing carbon dioxide emissions from power stations and industry. And we won’t be using hydrogen cars until we’ve developed practical ways of carrying enough hydrogen gas in the fuel tank. Deanna D’Alessandro’s understanding of basic […]

A naked scientist, exploring the oceans, amazing caves and much more: National Science Week biodiversity events

We’ve identified 135 Science Week events around Australia with a biodiversity connection. So we thought we’d share them with you in this special Science Week edition of our Biodiversity Year bulletin.

You can learn how to keep bugs alive, immerse yourself in flora and fauna on a walk through the forest, hear about the unique environment of Barrow Island in Western Australia and discover how a genetic disease in the Royal Family relates to biodiversity.

What does food do – time to move beyond the glycaemic index

It’s time to get smarter about food labelling according to Dr John Monro, speaking at the international chemistry conference in Melbourne this week.

“We need to know not just what is in the food, but what the food is going to do in our bodies,” he says. John is a researcher with the New Zealand Institute for Plant and Food Research.

“And we need easy to follow guides that make sense when we’re pushing our trolleys around the supermarket.”

Spinning the world clean

Prof Colin Raston and his colleagues in the Centre for Strategic Nano-Fabrication at the University of Western Australia are setting about cleaning up the world—and chemical industry in particular—through developing a suite of technologies to enable continuous, rather than batch, processing.

“We’re working at getting rid of the round-bottom glass in the laboratory, and the array of tanks and pipes in chemical plants.” [continue reading…]

Vegetable oil to lubricate your car, tractor and truck

IUPAC Symposium 6B – Crop Biofactories: Plants as Sustainable Bio-Production Systems for Industrial Raw Materials, Wednesday 3:30pm

Sten Stymne, Swedish University of Agricultural Sciences

Vegetable oil is the agricultural product that chemically most resembles fossil oils and has therefore great potential to replace it, says Sweden’s Sten Stymne.

He’s part of an 11-million-Euro global project to engineer seed oils for bio-lubricant uses.

Could your lawn, golf course or pasture make its own weedkiller?

IUPAC Symposium 4A – Natural Products, Tuesday 1:45PM – 3:00PM

Leslie Weston, Charles Sturt University, Wagga Wagga

Leslie Weston has discovered and patented two weedkillers made by plants. Now she’s investigating Patterson’s curse to see what tricks it uses to invade grasslands and repel herbivores. Her vision is to use plants or plant extracts to control plants, as an alternative to synthetic pesticides and herbicides.

Potato flakes for breakfast?

RACI Symposium – Cereals & Disease Prevention, Tuesday 4:30pm

Paul MacLean, University of Colorado

Resistant starch could transform our breakfasts, our gut health and help us lose weight.

Paul MacLean has shown that replacing simple sugars and digestible starch with starch that is resistant to digestion in the small intestine can have big consequences.

Greening agricultural sprays

IUPAC Symposium 1A – Formulation: Efficacy and the Environment

Ingo Fleute-Schlachter, Cognis, Germany

Friendlier pesticides are on the way. Every pesticide contains an active ingredient. But there is more in the can. The formulation may need additives and adjuvants which boost performance: working as emuslifiers, wetters, dispersants, or sticking agents to deliver the pesticide to where it’s needed – the surfaces of leaves for example.

New perfumes for bugs

IUPAC Symposium 4B – Natural Products, Tuesday 4pm

John Pickett, Rothamsted Research

John Pickett and his British colleagues are creating new kinds of perfumes or attractants for pest insects.

They’re employing farnesyl diphosphate—the ‘parent’ molecule  that insects use as the starting point for many chemical signals such as sex pheromones—to create new, more powerful attractants that will be cheaper and easier to make.

Use your spray smarter: save money and the environment

IUPAC Symposium 4B – Formulation, Efficacy and the Environment

Monday 4:30pm

Heping Zhu, United States Department of Agriculture

“Current label-recommended levels of pesticides for spray application technology, pest pressure and crop growth structure are vague, frequently resulting in excessive use of pesticide,” says Heping Zhu from the USDA in Ohio.
