There’s a lever on the back for this compression mechanism that you manually press down and a separate button to open the dustbin at the bottom. You can use the compression lever when it’s both closed and open. It did help compress the hair and dust while I was vacuuming, helping me see if I…
The original version of this story appeared in Quanta Magazine. When Todd Sacktor was about to turn 3, his 4-year-old sister died of leukemia. “An empty bedroom next to mine. A swing set with two seats instead of one,” he said, recalling the lingering traces of her presence in the house. “There was this missing…
When I reviewed the GR III, I wrote about how much I liked snap focus mode, which allows you to set a predetermined focus distance regardless of the aperture. I set up my GR III to use autofocus when I half-pressed the shutter and snap when I quickly pressed, so that snap focus fired off…
“We’ve listened carefully to feedback from our customers,” Instacart said in its statement. “And we understand that the tests we ran with a small number of retail partners that resulted in different prices for the same item at the same store missed the mark for some customers. At a time when families are working exceptionally…
The team members went through a process of incrementally determining what elements and molecules the bacterial strain could grow on. They already knew it could use oxygen, so they tested other combinations in the lab. When oxygen was absent, RSW1 could process hydrogen gas and elemental sulfur—chemicals it would find spewing from a volcanic vent—and…
A decade ago, kratom advocates fought a surprisingly successful campaign against a proposed Drug Enforcement Administration ban that claimed the obscure Southeast Asian plant posed “an imminent hazard to public safety.” They won bipartisan allies from Bernie Sanders to Rand Paul, and helped create a billion-dollar industry out of kratom, which has pain-relieving effects they…
Zuckerberg repeatedly fell back on accusing Lanier of “mischaracterizing” his previous statements. When it came to emails, Zuckerberg typically objected based on how old the message was, or his lack of familiarity with the Meta employees involved. “I don’t think so, no,” he replied when directed to clarify if he knew Karina Newton, Instagram’s head…
First, we tested the Whirlpool WFW5720RR for performance and found the washer to be excellent at cleaning clothes. After we removed the load, we monitored the humidity inside the drum. We then ran the Dry Drum cycle (which runs a fan and periodically tumbles the drum for four hours) and recorded the humidity again. After…
Forgive me for starting with a cliché, a piece of finance jargon that has recently slipped into the tech lexicon, but I’m afraid I must talk about “moats.” Popularized decades ago by Warren Buffett to refer to a company’s competitive advantage, the word found its way into Silicon Valley pitch decks when a memo purportedly…
They simmer steadily. A low-heat burner that’s capable of maintaining a steady temperature when simmering liquids is ideal, so you don’t need to stir constantly to avoid scorching, say, tomato sauce or chocolate. They bake and broil evenly. Cakes and cookies emerge uniformly baked from multiple racks. And the broiler heats evenly while still getting…
