Functional "Mini-liver" Created by 3D Bioprinting
Publicado em 18 de dezembro de 2019
Original 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.

Newly identified electric eel is the most powerful ever found, say scientists
Publicado em 11 setembro 2019Prepare yourself for a shock of the record-breaking variety – scientists have identified two new electric eel species, and one of them can put out a zap that’s stronger than any other animal we know about. The supercharged species is Electrophorus voltai, and it can discharge 860 V of electricity in a single shock, some way ahead of the 650 V shock that electric eels are normally associated with. It’s definitely enough to cause a human-sized creature some serious [...]ver notícia -
A shocking find : new high-voltage electric eels revealed
Publicado em 10 setembro 2019Call it a shock discovery: DNA research has revealed two entirely new species of electric eel in the Amazon basin, including one capable of delivering a record-breaking jolt. The findings are evidence, researchers say, of the incredible diversity in the Amazon rainforest — much of it still unknown to science — and illustrate why it is so important to protect a habitat at risk from deforestation, logging and fires. “In spite of all human impact on the Amazon rainforest in the [...]ver notícia
