De este modo, se evita un problema común en la mayoría de las técnicas de bioimpresión de tejidos humanos: la pérdida paulatina del contacto entre las células y, por consiguiente, la de la funcionalidad del tejido. En este estudio, la formación de los esferoides se concreta desde el proceso de diferenciación, cuando las células pluripotentes se transforman en células del tejido hepático (hepatocitos, células [...]

HOUSTON – (Nov. 13, 2019) – A lightweight material full of holes is nearly as hard as diamond. The mere dents left by speeding bullets prove it. Researchers at Rice University’s Brown School of Engineering and their colleagues are testing polymers based on tubulanes, theoretical structures of crosslinked carbon nanotubes predicted to have extraordinary strength. The Rice lab of materials scientist Pulickel Ajayan found tubulanes can be mimicked as scaled-up, 3D-printed [...]

Researchers have identified a genetic signature with prognostic value for certain kinds of breast cancer. The discovery also contributes to a better understanding of the molecular mechanisms of pathological angiogenesis, the aberrant proliferation of blood vessels that occurs during cancer and other diseases. The research, published in the journal PLOS Genetics, combined a study of the genes involved in retinopathy, as a model of angiogenesis, with analysis of transcriptomic gene [...]

Experiments performed by Brazilian scientists showed that Zika virus inhibits tumor cell proliferation even when inactivated by high temperature; the study was supported by FAPESP and published in Scientific Reports The study was led by Rodrigo Ramos Catharino, a professor in UNICAMP’s School of Pharmaceutical Sciences. In experiments with a human prostate adenocarcinoma cell line (PC-3), the scientists found that Zika inhibits tumor cell proliferation even when inactivated by high [...]

Billions of years ago, asteroid collisions resulted in the ejection of fragments hundreds of kilometers across and sharing similar orbits. The resulting groups are known as asteroid families. Other asteroid groups formed as a result of rotational fission, which happens when a rapidly spinning body reaches critical rotation speed and splits into relatively small fragments only a few kilometers across. Scientists have always thought about fission clusters as entirely distinct from collisional [...]
