How green biotech turned white and blue

This year, midway through Argentina’s 2005–2015 Strategic Plan for Biotechnology, a long-stalled update of the Seed Law circulating in Buenos Aires may finally reach the legislative floor. The current law, which facilitated the rapid boom of transgenic crops in Argentina in the 1990s—60% of Argentina’s soy crop was genetically modified for herbicide resistance within three years of the introduction of Roundup Ready soy—is a source of conflict over intellectual property rights, as it permits farmers to retain seeds without paying royalties.

However, the meteoric rise in GM crop production was not solely the function of the seed law. Compatible agricultural practices in the early 1990s and a welcoming government contributed. Critics and fans alike say it’s a model from which other developing countries can learn important lessons. Continue reading How green biotech turned white and blue

Brewing a Cup of Volcanic Tea

Many families along Iceland’s fertile southern coast can spin a good yarn about a close escape from an exploding volcano. Take Kristín Vogförð’s  grandfather, who was tending sheep on the eastern slopes of Katla when it erupted in 1918, melting glacial ice and violently flooding the rivers and fields below. According to an account by the geophysicist from the Icelandic Meteorological Office (IMO), he and the other shepherds rode their tough Icelandic horses through icy waters to safety. Unfortunately, his sheep were not so lucky.

In April, I joined a group of Icelandic volcano experts on a field trip to study rocks, gases and river runoff from Eyjafjallajökull. I witnessed modern escapes and came away impressed by how much Iceland’s scientists are doing to learn all they can from the latest eruptions, which have already begun to take a large toll on the small country’s tourism and agriculture industries.

Iceland Eruptions Fuel Interest in Volcanic Gas Monitoring

REYKJAVIK–As a brown cloud of ash drifts down from the slopes of Eyjafjallajökull toward their truck, Hanna Kaasalainen warns a colleague that their gas masks won’t be much good against carbon dioxide. The masks filter out poisonous gases released by magma such as sulfur dioxide, but carbon dioxide can simply displace oxygen in the air, asphyxiating the researchers as they take ash samples alongside a haze-enshrouded, deserted road. “We shouldn’t stay very long,” the University of Iceland geochemistry graduate student advises, before strapping on a bright yellow mask and opening the door.
