noon on the center divider of Interstate 15 in the Cajon Pass. It quickly grew to 1,100 acres, or nearly 2 square miles, jumping the freeway and burning chaparral in rolling hills that form the nearby San Bernardino National Forest and rural areas of San Bernardino County. The fire was fueled by winds up to 15 mph and 90 degree temperatures, but by dusk cooler weather and calmer winds helped 750 firefighters surround 20 percent of the blaze, U.S. Forest Service spokesman John Miller said. "The fire laid down pretty good, firefighters have made very good progress," Miller said. The fire destroyed two mobile homes and damaged two other structures. A firefighter suffered heat exhaustion and another suffered a medical-related injury, he said. An evacuation was ordered as the fire moved northwest toward large ranch homes in the Oak Hills area. Fire crews were placed to defend the houses as the flames came within yards of some of them. By evening, authorities determined it was safe for those who live on the north and west side of the fire to come back. Miller said firefighters were focused on putting out hot spots and completing containment lines through the night.

Brain-reading devices would likely first help paralyzed people such as physicist Stephen Hawking, but still won't happen for years, Botvinick cautioned. There is also the problem of making brain scan technologies more portable, if ordinary people hope to get a shot at freeing up their hands from typing. Yet Botvinick envisioned a future where such technology could translate any mental content about not just objects, but also people, actions, abstract concepts and relationships. One existing technology allows patients suffering from complete paralysis — known as locked-in syndrome — to use their eyes to select one letter at a time to form words. Another lab prototype allows patients to make synthesized voices by using their thoughts to create certain vowel sounds, even if they can't yet form coherent words. But truly direct thought-to-word translation remains out of reach. That's where the current work comes into play. Botvinick had first worked with Francisco Pereira, a Princeton postdoctoral researcher, and Greg Detre, a researcher who obtained his Ph.D. from Princeton, on using brain-activity patterns to reconstruct images that volunteers viewed during a brain scan. But the research soon inspired them to try expressing certain elements in words rather than pictures. First, they used a Princeton-developed computer program to come up with 40 possible topics based on Wikipedia articles that contained words associated with such topics. They then created a color-coded system to identify probability of certain words being related to an object that a v
