At least 66 people are dead and dozens left injured after an oil pipeline exploded in Mexico on Friday, BBC reports.

Details: The pipeline is believed to have been "ruptured by suspected oil thieves," a rampant and illegal practice that cost Mexico about $3 billion last year, according to BBC. President Andrés Manuel López Obrador, who traveled to the site of the blast in Tlahuelilpan on Saturday, told reporters that the incident "strengthened" his fight against theft, and that the "most important thing now is to look after the injured, to save lives."

While the U.S. awaits the consequences of a breakdown in the polar vortex, Australia has been sizzling through an unrelenting series of heatwaves that have shattered all-time records.

Newly introduced electric vehicles are capable of charging wirelessly rather than tethered to a power cable, a technology that could one day help autonomous EVs stay running around the clock.

Why it matters: The ability to charge whenever they have a chance — through wireless charging source pads embedded in roadways and parking spots — would make AVs more efficient because they would never have to be taken out of operation for refueling.

Tesla is slashing its full-time workforce by about 7% as production of the Model 3 sedan ramps up, CEO Elon Musk said in a company email on Friday.
