Machines can be trained to classify images and thus identify tumors in CT scans, mineral compositions in rocks, or pathologies in optical microscopy analyses. This artificial intelligence technique is known as machine learning and has gained new applications in recent years. Machine training is carried out via the repetition of images used as examples of a particular context or situation and the adequate preparation of that material requires the effort of experts from a variety of areas. The [...]

Scientists have discovered a huge exoplanet that’s 13 times bigger than Jupiter – the biggest planet in our solar system. The researchers, from the Sao Paulo Research Foundation, discovered the mysterious planet using NASA ’s Kepler Space Telescope. Leonardo Andrade de Almeida, who led the study, said: “We succeeded in obtaining pretty solid evidence of the existence of a giant exoplanet with a mass almost 13 times that of Jupiter [the largest planet in the Solar System] in an evolved [...]

Liposomes are small spherical vesicles with walls comprising two layers of lipids and containing an aqueous core. These artificial structures have been developed for drug delivery or as carriers of active substances in cosmetic products. Another possible application involves the encapsulation of magnetic nanoparticles in liposomes to use them to transmit signals. This possibility is discussed in an article published by a group of Brazilian researchers supported by São Paulo Research [...]

Materials that are hybrid constructions (combining organic and inorganic precursors) and quasi-two-dimensional (with malleable and highly compactable molecular structures) are on the rise in several technological applications, such as the fabrication of ever-smaller optoelectronic devices. An article published in the journalPhysical Review Bdescribes a study in this field resulting from the doctoral research of Diana Meneses Gustin and Luís Cabral, both supervised by Victor Lopez Richard, a [...]

Tau Flow, a computational engineering startup based in Campinas, São Paulo State, Brazil, offers the market customized mathematical solutions for the optimization of project performance. It uses 3D computational fluid dynamics (CFD) to develop “virtual prototypes” of any process or environment that involves flows of liquids or gases (defined in physics as fluids).“ Our prototyping
