Brazilian firm leads the application of synthetic diamonds in dentistry
Publicado em 23 novembro 2017
A device developed by CVDVale allows for the reduction of noise and pain in the treatment of caries; the company is accountable for the world's first courses in ultrasonic dentistry and now wants to apply ultrasonic technology in orthopedic surgeries.
Clorovale Diamantes Indústria e Comércio, a Brazilian company based in São Paulo State, was founded in 1997 by a group of researchers affiliated with the National Space Research Institute (INPE). Trading as CVDVale, the firm pioneered the [...]

New physical model explains the origin of Earth’s water
Publicado em 17 novembro 2017Equipped with Newton’s law of universal gravitation (published in Principia 330 years ago) and powerful computational resources (used to apply the law to more than 10,000 interacting bodies), a young Brazilian researcher and his former postdoctoral supervisor have just proposed a new physical model to explain the origin of water on Earth and the other Earth-like objects in the Solar System. André Izidoro, from the School of Engineering of Sao Paulo State University in Guaratinguetá, [...]ver notícia -
Star kills its ‘congenial’ to form together a dwarf-binary system, astronomers confirm
Publicado em 11 novembro 2017A group of Brazilian astronomers observed a pair of celestial objects rarely seen in the Milky Way: a very low-mass white dwarf and a brown dwarf. What makes this binary system so unique is its origin: the white dwarf’s existence was prematurely cut off by its companion, a brown dwarf, which caused its early death through “malnutrition” or loss of matter. A white dwarf is the endpoint of the evolution of an intermediate- or low-mass star, with a mass between 0.5 and 8 times that of our [...]ver notícia -
Brazilian researchers find more significant cognitive deficits among early-onset cocaine users
Publicado em 22 outubro 2017People who begin using cocaine during adolescence display more significant cognitive deficits than people who begin using the drug in adulthood. That which experts in neuroscience have long suspected has been given an objective confirmation by researchers working at the University of São Paulo’s Medical School (FM-USP), in Brazil. When scientists compared the two groups of cocaine users, they observed pronounced differences, mainly in specific neuropsychological functions such as sustained [...]ver notícia -
Nanoparticles pollution rises 30 percent when flex-fuel cars switch from bio to fossil
Publicado em 29 agosto 2017When ethanol prices at the pump rise for whatever reason, it becomes economically advantageous for drivers of dual-fuel vehicles to fill up with gasoline. However, the health of the entire population pays a high price: substitution of gasoline for ethanol leads to a 30% increase in the atmospheric concentration of ultrafine particulate matter, which consists of particles with a diameter of less than 50 nanometers (nm). The phenomenon was detected in São Paulo City, Brazil, in a study [...]ver notícia -
Study reinforces the Amazon forest’s importance in regulating atmospheric chemistry
Publicado em 06 agosto 2017Airborne measurements made as part of the Green Ocean Amazon experiment (GOAmazon) show that the Amazon rainforest emits at least three times more isoprene than scientists had previously thought. The research findings were published in Nature Communications. According to Paulo Artaxo at the University of São Paulo’s Physics Institute (IF-USP) in Brazil and a co-author of the study, isoprene is one of the main precursors of ozone in the Amazon, and it indirectly influences the balance of [...]ver notícia
