(Nanowerk News) - In our solar system, an asteroid orbits the Sun in the opposite direction to the planets. Asteroid 2015 BZ509, also known as Bee-Zed, takes 12 years to make one complete orbit around the Sun. This is the same orbital period as that of Jupiter, which shares its orbit but moves in the opposite direction to the planet's motion.The asteroid with the retrograde co-orbit was identified by Helena Morais, a professor at São Paulo State University's Institute of Geosciences & [...]

(Nanowerk News) - A transistor that simulates some of the functions of neurons has been invented based on experiments and models developed by researchers at the Federal University of São Carlos (UFSCar) in São Paulo State, Brazil, Würzburg University in Germany, and the University of South Carolina in the United States.The device, which has micrometric as well as nanometric parts, can see light, count, and store information in its own structure, dispensing with the need for a complementary [...]

(Nanowerk News) - Researchers at the University of Campinas's Gleb Wataghin Physics Institute (IFGW-UNICAMP) in São Paulo State, Brazil, have theoretically developed a silicon photonic device that would enable optical and mechanical waves vibrating at tens of gigahertz (GHz) to interact.The proposed device resulted from the projects "Nanophotonics in Group IV and III-V semiconductors" and "Optomechanics in photonic and phononic crystals", both supported by FAPESP. It was described in an [...]

(Nanowerk News) Over the past two years, 137 experts from 24 countries and 82 institutions have collaborated to analyze a range of issues related to the sustainability of bioenergy production and use. The resulting report Bioenergy & Sustainability: Bridging the Gaps (pdf), will be launched at a symposium at the World Bank, on September 28, 2015, in Washington DC, USA. In the symposium, authors will highlight the key findings and discuss the opportunities for sustainable energy in [...]

(Nanowerk News) Agrindus, an agribusiness company located in São Carlos, São Paulo state, Brazil, has increased the shelf life of grade A pasteurized fresh whole milk from seven to 15 days. This feat was achieved by incorporating silver-based microparticles with bactericidal, antimicrobial and self-sterilizing properties into the rigid plastic bottles used as packaging for the milk. The technology was developed by Nanox, also located in São Carlos. Supported by FAPESP's Innovative [...]
