While the air temperature between fillings varied by up to 12° F, the fuel in our underground tank stayed at a steady 62° F. As a result, we found that after the first few gallons were pumped, the fuel temperature coming out of the nozzle varied very little between morning and afternoon. At both morning…
They stuffed a real-life ray gun into a 747 to shoot down ballistic missiles and stuck a laser on top of a Humvee to zap roadside bombs. For more than 50 years, the United States military and its researchers have tried to develop laser weapons. None of them panned out. But now, the US Army…
For additional protection, look for a space heater equipped with an appliance leakage current interrupter (ALCI) plug, says Samantha Ostrander, who oversees CR’s space heater tests. These bulky plugs—similar to those seen on hair dryers—safeguard against differences in current and can also protect against a dangerous electrical shock. Like GFCI outlets, ALCI plugs typically feature…

We have lost pairs to folks standing on them, cats and robot vacuums attacking the cables, and chairs rolling over them.

Three to four days in the fridge—that’s the max for cooked foods, says James E. Rogers, PhD, director of food safety research and testing at Consumer Reports. “That means no week-old turkey sandwiches,” he says. After that, their taste and safety may suffer. If you don’t think you’ll get through everything during that time, you…
As more robots start showing up in warehouses, offices, and even people’s homes, the idea of large language models hacking into complex systems sounds like the stuff of sci-fi nightmares. So, naturally, Anthropic researchers were eager to see what would happen if Claude tried taking control of a robot—in this case, a robot dog. In…
