Researchers at Delft University of Technology have built a navigation method for small drones that copies one of nature’s most efficient routines. Honeybees fly long distances along twisting routes yet still head home with striking accuracy. The new system lets a drone do something similar after just one short practice flight near its base, all while using a learning program small enough to fit in the memory of a basic phone app icon.

Mexico Olinia Uno EV
President Claudia Sheinbaum drove immediately into the stage set up inside a Mexican air force hangar in Mexico City, giving the world its first glimpse of the Olinia Uno, a 100% Made-in-Mexico electric vehicle. The project was spearheaded by a team of Mexican engineers and academics who worked tirelessly to create a vehicle that could help propel the country into the electric-vehicle era. The Olinia Uno is a compact six-seater van that starts at 150,000 pesos, or around $8,000 to $8,600 USD at current exchange rates. Its intended demographic is, as expected, people who take short trips about the city, which is exactly what most driving in Mexico’s cities involves.

Fixing World's Worst E-Bike Reevo
A viewer handed over a Reevo hubless electric bike with one clear condition. Fix it first, then bring it back better than before. The machine already carried a heavy reputation for every shortcut and oversight that can sink an ambitious design. Original plans leaned hard into a futuristic look. Large hubless wheels replaced traditional spokes. A sculpted body hid most of the mechanics. Nearly every useful function, from lights to wheel locks to performance modes, ran through a smartphone app. Once the company behind that app stopped supporting it, large parts of the bike simply stopped responding.
