Scientists, patients and government entities in Argentina have reached an agreement to legislate stem cell therapies. The law “should address the scientific and therapeutic aspects of these cellular tools, always from a bioethical perspective, while guaranteeing the health protection of citizens,” stated Lino Brarañao, Argentina’s Minister of Science and Technology.

Giant African land snails are invading Latin America

by Ali Hendren

In 1988 at an agribusiness expo in Curitiba in southern Brazil, giant African land snails (Achatina fulica) were heralded as a promising new food source to replace smaller escargot snails. The introduction at the fair was so widely advertised and aggressively marketed that commercial breeders, cooperatives and even private homeowners began rearing the snails–endemic to eastern Africa–immediately with kits sold at the expo.

“The snails were supposed to represent social and economic progress for Brazil,” says Roberto Vogler, an Argentine scientist who studies the snails along the border his country shares with Brazil. “They were going to position the country as the world’s leading supplier of escargot.”

But a booming escargot market in Brazil never materialized. Many of the smaller producers had neither the means to properly process the meat nor the public demand to drive a now flooded market. Frustrated with their failed investment, operations were abandoned and snails were released into the wild in overwhelming numbers.

Today, the infestation has spread throughout Latin America–and not at a snail’s pace. They’ve invaded 24 of Brazil’s 26 states, spread through Venezuela and Colombia and have breached the borders of Paraguay, Argentina, Ecuador and Peru–posing both an agricultural and a public health threat. The snails are sweeping the continent carrying parasites and an appetite for most any crop.

On paper, the introduction of A. fulica for escargot farming in Brazil appeared promising. The snails are larger Continue reading “Giant African land snails are invading Latin America”

Brain controlled robotics in Argentina, talking about bats in Costa Rica, and outsourcing science research of Bolivia’s salt flats

The West Antarctic began to form approximately 22,000 years ago according to a study recently published in the journal Nature. They found, while analyzing a block of ice two miles deep, that a part of the white continent was formed long before the rest of the continent.

The South Atlantic, specifically the Gulf of San Jorge, will be studied jointly by Argentine and Canadian scientists, says the Ministry of Science and Technology of Argentina. The project will start in January 2014, will be done aboard the ship Coriolis II and require an investment of one million dollars.

For 10 years the Faculty of Agronomy at the UBA has been working with farmers in the municipality Daireaux, located 400 km from Buenos Aires. Through tax benefits, producers are encouraged to conserve soil and rotate crops in addition to adopting traditional farming practices in the area. The producers involved in the project have seen significant improvements in organic matter content and soil stability.

A group of scientists in Cordoba has created an innovative technology that allows people with physical disabilities to switch on the lights or lower the blinds in their homes through a system that decodes their brainwaves and transforms them into intelligible orders.
