(FCM - PB - 2012/1) El corazn humano genera tanta presin cuando bombea la sangre, que podra arrojarla hasta 10 metros de distancia. Con sus aproximadamente 300 gramos de peso, un corazn de un promedio de vida de 70 aos realiza un trabajo suficiente para subir cinco vagones cargados desde el nivel del mar hasta la cima del monte Everest. Adems, el corazn podra impulsar por las venas, en el tiempo mencionado, alrededor de 15 millones de litros de lquido. (FLORES y SILVA. Uno modular. In: www.quecurioso.com.ar.)

(FCM PB - 2012/2) Researchers from Brazilian museum Emlio Goeldi, in the northern state of Par, have launched an ambitious project: Making each of the thousands of animal and plant species that inhabit the Amazon forest available on the Internet. At the moment, the Center of Biodiversity has a list of some 3,000 species, from mammals to spiders, all of which are native to Par. In the new list, researchers want to include images and sounds of each species. The Amazon forest project is intended to eventually be expanded to include other Brazilian states, as well as neighboring countries, like Peru and Colombia. Even in groups which have been broadly studied, such as mammals and birds, about 10% of Amazonian species are still unknown. ―And there are lots more if you think of reptiles and amphibians‖, says biologist Ulisses Galatti, one of the projects coordinators. In addition to the website, the Goeldi Museum will publish a book named ―Species of the Millennium‖, which tallies the 130 new discoveries made by the museum researchers between 2000 and 2011.
