Almost everything is more expensive these days: Gas prices have reached record highs. Grocery prices are through the roof. And as we approach the holiday season, all that inflation leaves little money for extras like entertainment, travel, or shopping — or does it? For the scoop on how inflation will influence the holidays, we checked in with UNLV hospitality professor, tourism researcher, and consumer behavior expert Amanda Belarmino.

With electric vehicles becoming more and more common, the risks and hazards of a cyber attack on electric vehicle charging equipment and systems also increases. Jay Johnson, an electrical engineer at Sandia National Laboratories, has been studying the varied vulnerabilities of electric vehicle charging infrastructure for the past four years.
Diesel-fueled freight trucks play an outsized role in producing India’s total greenhouse gas and air pollution emissions. While the country has promoted policies to transition to electric vehicles for public transportation buses and cars, batteries that can power such large trucks have been too heavy and expensive to make their electrification possible. A new study shows that advances in battery technology and dramatically decreased battery costs in recent years have changed that. With the right policies and incentives, battery electric trucks would be more affordable to operate than diesel, and India could become a world leader in producing electric vehicles.

Synthetic fuels produced from renewable sources, so-called refuels, are deemed potential game changers in fighting climate change. Refuels promise to reduce CO2 emissions by up to 90% compared to conventional fuels and they allow for the continued use of existing vehicle fleets with combustion engines and of the refueling infrastructure, from fuel production to transport to sales. Researchers of Karlsruhe Institute of Technology (KIT) carried out extensive fleet tests in a large-scale project with industry partners and proved that refuels can be used in all vehicles and produced in large quantities in the foreseeable future. The results of the research project “reFuels – Rethinking Fuels” were presented on Monday, September 19, in Karlsruhe.
