A breakthrough for Golden Rice
More than 10 years after the release of Golden Rice – rice genetically modified to contain high levels of provitamin A – trials are about to begin in Bangladesh and the Philippines to assess whether eating Golden Rice really does increase vitamin A levels in the body. Vitamin A deficiency is a cause of blindness…
Using satellites to map forests’ carbon stock
An estimated 20% of the world’s anthropogenic emissions of CO2 derive from deforestation and degradation of tropical forests. Nonetheless, data and hence knowledge on the condition and coverage of these forests is incomplete, which makes it impossible to accurately monitor future changes. For this reason, the Woods Hole Research Center has initiated a three-year project…
Alternative energy sources – is wind the answer?
The damage caused to the Fukushima nuclear power plant by the earthquake and tsunami recently raised safety issues to a supposedly clean energy. The past twelve months have seen concerns with the traditional and dwindling traditional forms of energy; for example the coal mining accidents in Chile, New Zealand and China, oil and gas…

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

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…
Global research efforts tackle food security.
On January 28, Dave Simpson wrote on Hand picked (‘Redesigning the global food system’) about the recent release of the Foresight report, The Future of Food and Farming, which argues for fundamental change to the global food system if a rapidly expanding global population is to be fed over the next 40 years. On 10…
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…
