Climate of changing public opinion
This week is Climate Week in the UK, which aims to get the public involved in thinking about climate change. In the scientific community, there is an increasing level of consensus about climate change and the need to take drastic action to limit severe consequences. However, in order to introduce challenging policies, there must be…
Natural hazards – how do we know when they’re coming?
The earthquake that hit Japan’s northeast coast today had a magnitude of 8.9 in the Richter scale and generated a 4-metre tsunami that swept boats, cars, buildings and tons of debris miles inland. Fires triggered by the quake burned out of control up and down the coast. Only a couple of days ago, I…
Aid donors join forces to fight wheat rust
Emerging strains of stem rust disease of wheat, such as Ug99, are spreading out of East Africa and threatening the world's wheat supply. But the fight against this disease received a boost this week from a collaboration between the UK's Department for International Development (DFID) and the Bill & Melinda Gates Foundation. The organisations have…

Does rust-free rice hold the secret?
All cereals, except rice, are susceptible to rust. Wheat, maize, barley, millet, triticale, and oats all get rust. The spores of rust fungi land on a host plant, germinate, and grow toward a stomatal pore on the leaf surface to initiate infection. Rust infections produce red or yellow pustulating spores that give infected plants a…

Plastic bag ban
Recently, I read an article in the January 2011 issue of BioCycle reporting a ban on non-biodegradable plastic bags, which went into effect in Italy on January 1, 2011. A clause will allow shops to use bags they already have stockpiled until they run out, after which biodegradable plastic or paper or reusable cloth bags…

The consultation on the selling-off of English forests, which was going to go on until April 2011 has been officially cancelled a few moments ago. There was widespread opposition to the forestry sell-off, which would have seen private companies and some…
Hessian fly heading for the sack
Wheat crops suffer millions of dollars’ worth of damage each year due to the hessian fly, Mayetiola destructor. The most effective control method is genetic resistance, when wheat resistance genes cause death of the attacking larvae by activating a defense response against avirulent hessian flies. Unfortunately this has led to flies that can overcome resistant…
