Peru’s Humboldt scientific cruise vessel set sail for Antarctica to identify research areas on the white continent from now until 2021. The mission is further comprised of Argentine, Chilean, Brazilian, Chinese, American and Ecuadorian scientists.
Scientists from the Smithsonian Tropical Research Institute are carrying out a study of 700 hectares close to the Panama Canal to determine the “sponge effect” of tropical forests. This effect decreases runoff during heavy rains and gradually releases the stored water in times of drought.
Chagas disease, caused by the parasite Trypanosoma cruzi and transmitted by an insect that feeds on human blood, is a scourge of the rural poor in Latin America. For treatment of this disease, Canadian researchers found two compounds that inhibit an essential protein of the parasite.

Colombian researchers have found the first hemoparasite affecting hummingbirds. Leucocytozoon quynzae is transmitted by an insect and was known until this investigation to infect birds like ducks and turkeys.
A biomedical research lab in Buenos Aires is studying the role of the ubiquitin protein and other proteins with similar functions in protein degradation and their involvement in diseases and the control of biological processes.
The biotechnologist Julieta Cabello was lauded as Santafe, Argentina’s scientist of the year. She looks at the HaHb1 factor in sunflower plants and how it induces resistance to certain abiotic stresses such as drought and salinity.
A scanner will be available in Jose de San Martin hospital in 2014 to detect oxidative stress and aging. This device emits white light at the skin which is absorbed by carotenoids (antioxidants) and returned to the source as a spectrum of colors ranging from blue to red. The more blue is in the spectrum, the more carotenoids in the skin.
Mexican scientists have made important advances in the study of cervical cancer.
