A decade ago, this same team made the first-ever detection of a ring around an asteroid. The [...]ver notícia -
Functional "Mini-liver" Created by 3D Bioprinting
Publicado em 18 dezembro 2019Original story by Maria Fernanda Ziegler, Agência FAPESP Using human blood cells, Brazilian researchers have succeeded in obtaining hepatic organoids (“mini-livers”) that perform all of the liver’s typical functions, such as producing vital proteins, storing vitamins, and secreting bile, among many others. The innovation permits the production of hepatic tissue in the laboratory in only 90 days and may in the future become an alternative to organ transplantation. The [...]ver notícia -
Innovative management system for tilapia fish farms cuts feed costs
Publicado em 27 junho 2018(Fundação de Amparo à Pesquisa do Estado de São Paulo) System uses circular aluminum tanks that float on rafts of plastic bottles releasing a correct dose of fish food 48 times per day. The new method also reduced mortality in 12% by dispensing switching of tanks in fish grading. An innovative tilapia farming system that reduces both expenditures on fish feed and mortality rates, among other benefits, has been developed by Brazilian firm Fisher Piscicultura and is undergoing final testing [...]ver notícia -
