If one of the world's biggest car manufacturers decides not to attend one of the world's most prestigious motor shows, should the organisers be getting worried? The Mondial de l'Automobile, also known as the Paris Motor Show, gets under way today. For 16 days, it will play host to the great and good of the global motor industry. First held in 1898, it now takes place once every two years, alternating with the equally high-profile Frankfurt Motor Show. Traditionally, it provides an opportunity for manufacturers to wheel out their gleaming new models, indulge their engineers' flights of fancy by producing outlandish and futuristic concept cars, and generally bask in the media spotlight.
Many biomolecular motors catalyze the hydrolysis of chemical fuels, such as adenosine triphosphate, and use the energy released to direct motion through information ratchet mechanisms. Here we describe chemically-driven artificial rotary and linear molecular motors that operate through a fundamentally different type of mechanism. The directional rotation of - and catenane rotary molecular motors and the transport of substrates away from equilibrium by a linear molecular pump are induced by acid-base oscillations. The changes simultaneously switch the binding site affinities and the labilities of barriers on the track, creating an energy ratchet. The linear and rotary molecular motors are driven by aliquots of a chemical fuel, trichloroacetic acid.
The stars of shows such as "The Walking Dead" and "Sharknado" are converging on a suburban Detroit convention center for what organizers say will be the biggest Motor City Comic Con yet. The 27th annual three-day pop-culture extravaganza that got underway Friday will welcome dozens of celebrities from the worlds of TV and film as well as hundreds of comic book creators, writers and artists and tens of thousands of fans to the Suburban Collection Showplace in Novi. Motor City Comic Con owner Michael Goldman says it's a place where fans' "inner geek can come out." Ian Ziering and Tara Reid, who star in this summer's fourth installment of the campy smash "Sharknado" franchise on SyFy, signed autographs and posed for photos during Friday's opening-day session.

Good news, hybrid fans: One of the industry's best hybrids is back. Honda announced Thursday morning that it will be bringing back the Accord Hybrid for the 2017 model year after having discontinued it for 2016. I guess engineers just needed a year off. Along with new front-end styling, the 2017 Accord Hybrid will boast an impressive, EPA estimated 49-miles-per-gallon fuel-efficiency rating, as well as Honda Sensing, the Japanese carmaker's suite of advanced safety and semi-autonomous tech. Honda has outfitted the Accord Hybrid with both Apple CarPlay as well as Android Auto.
