Research to see if there are Links between the action of Mate Water and Mouth Cancer

Mate is a well rooted Argentinean and Uruguayan custom. The way to prepare it is so diverse as there are regions in Argentina, but everywhere the common factor is the high temperature of the water. This detail led two Faculties of Odontology in Argentina and Uruguay to investigate if the thermal action of mate is a risk factor which predisposes to mouth cancer.

It is estimated that if its applicability is proved, laparoscopic surgery will present advantages compared to the traditional technique of the autopsy and that they will be able to save time in the opening and closing of the body, samples for biopsies will be taken and whereas the traditional method takes three hours, the laparoscopy will take twenty minutes.

A High Extermination Power Trap against Vinchucas

Researchers tried to improve the design of a trap to attract, infect and kill vinchucas, the vector insect for Chagas-Mazza disease, the most important parasitic disease in Latin America, which in Argentina, according to the data provided by the Ministry of Health, causes more than 10 deaths per week. The trap is an effective alternative to eliminate the vectors resistant to chemical insecticides and besides, it requires a low production and application cost.

With the aim of tracking the habitat and distribution of these animals the researcher uses traps for specimens and analyzes bone remains regurgitated by owls, barn owls and eagles.

This was demonstrated by a group of researchers from Chubut which put collars with GPS to sheep in order to know their route by satellite images, among other working methods. It was determined that the disappearance of soft grass and its replacement by hard grass as a consequence of the shepherding habits make the ecosystem dryer.
