Not-so-gracefully going grey? Blame it on stress, science says. Physical stress can trigger melanin-producing cells in hair follicles, called melanocytes, to stop producing color — thus turning hair white or grey, according to researchers from Harvard and the Center for Research on Inflammatory Diseases (CRID) in São Paulo. The good news is, there might be a way to stop it. “For the longest time it’s been said that stress makes the hair turn white, but until now [...]

Scientists have always thought about fission clusters as entirely distinct from collisional families. Now a study conducted by researchers affiliated with UNESP has shown that fission clusters may originate from collisional families in some cases 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 [...]

In a process similar to 3D printing, it is possible to artificially create tissues by using cells and biomaterials. Bioprinting has allowed scientists to create organoids, meat, skin and bones. Researchers from Brazil have now bioprinted, ‘mini-livers’ that can perform all the functions of a liver. The printed organoid can produce vital proteins, store vitamins, secrete bile, and all the other functions that are carried out by a liver. Researchers from the Human Genome and Stem [...]

Researchers from Brazil have successfully created Mini Liver With the help of 3D Bioprinting. The Mini Liver performs all the liver’s typical functions, such as producing vital proteins, storing vitamins, and secreting bile, among many others. The breakthrough technology developed by the researchers can produce hepatic tissue in the laboratory in only 90 days. This technology in the future may become an alternative to organ transplantation. This study by Brazil researchers combined [...]

New study has succeeded in obtaining hepatic organoids ("mini-livers") that perform all of the liver's typical functions, like producing vital proteins, storing vitamins, and secreting bile, among many others using human blood cells. The innovation permits the production of hepatic tissue in the laboratory in only 90 days and may, in the near future, become an alternative to organ transplantation. The findings of the study are published in the journal Biofabrication. The study [...]

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. The [...]

As the man of science reiterated, greenhouse gases retain the thermal energy mirrored by the layer. However, in soils of tropical forests, like the Amazon, components like alkane series and inhalation general anaesthetic square measure actively recycled through biogeochemical processes. "This was incontestible by measure subterranean microorganism activities alongside gas flows," aforementioned Tsai, UN agency has been coordinative a study at intervals the scope of the metropolis [...]

Based on the information obtained from this latest whole-genome sequencing effort, researchers at the USP are developing tools for the genetic improvement of sugarcane and testing several candidate genes in Genetically Modified (GM) plants. An international group of researchers led by Brazilian scientists has assembled the most complete genome sequence of commercial sugarcane. They mapped 373,869 genes or 99.1% of the total genome. This feat is the result of almost 20 years of research [...]

The burning of sugarcane, carried out to eliminate dry leaves before harvesting, for years altered the air quality in the central region of the State of São Paulo, Brazil. The particles launched into the atmosphere during the process were visible to the region’s inhabitants and were deposited in the streets and on cars. Atmospheric pollution also caused respiratory problems among the population, impacts on biodiversity and the native vegetation, and contaminated [...]
