Petites plantes

advertisement advertisement advertisement Plants don’t usually say much. So, it can be harder to understand what they need compared to more vocal organisms such as humans. But, just like us and our nerves, plants send important messages from cell to cell via electrical signals. Now, with technology that helps analyze those signals, we may better understand what’s really eating at our greener brethren. advertisement advertisement When plants get stressed because of hunger, thirst, or insect attacks, they relay signals about that stress between cells. Roots may send signals when the plant is thirsty, for instance. Until now, farmers have relied solely on secondary indicators for finding problems with their crops, for instance by checking under roots for insects or looking for signs of drought, which can be labor-intensive. A new technology, PhytlSigns , pairs this electrophysiological knowledge with artificial intelligence to … [Read more...] about These plants can alert their owners when they’re thirsty

advertisement advertisement advertisement Neighborhoods that were redlined in the past—meaning that racist, government-backed maps marked them as “high risk” for home loans because people of color lived in the area—often still struggle with poverty today. They also tend to be different from richer neighborhoods in another way: They have vastly fewer trees. advertisement “If you look at a map of most American cities, you’ll find that tree canopy cover tracks along income lines,” says Sarah Anderson from the nonprofit American Forests . “Wealthier communities have more trees, and lower-income communities have fewer trees. And this is the result of decades of discriminatory housing and planning purposes.” The jobs, for 25 people in the five cities, also come with support like subsidies for transit and childcare. In the long term, it can lead to careers. “About a quarter of tree trimmers are self-employed in three years,” she says. “So … [Read more...] about This new tree corps will hire people to plant trees in low-income neighborhoods

advertisement advertisement advertisement It’s been a few years since the Impossible Foods and Beyond Meat burgers began showing up in grocery stores and restaurants. Despite their popularity, critics note that high-tech meat alternatives don’t exactly deserve a health halo . Perhaps in response, Impossible Foods r eleased its 2.0 version in 2019 , with 36% less sodium and 43% less saturated fat. Late last year, Beyond Meat announced its plans to debut a newer, leaner patty with less saturated fat as well. advertisement advertisement This seems like a good thing—companies making their products healthier is always a step in the right direction, isn’t it? 14.5% and 18% of global greenhouse gas emissions. Researchers have concluded that without significantly changing our diet it will be impossible to mitigate the environmental devastation. And that’s the rub: While most people know overconsumption of meat is directly … [Read more...] about Plant-based burgers aren’t a health food. That’s a good thing

advertisement advertisement advertisement Okay, quick, name the first ad to run during the Super Bowl! advertisement advertisement Of course you can’t remember. It doesn’t help that most brands have been teasing out or just flat out releasing their ads for weeks now, all trying to squeeze another drop of attention out of the entire spectacle. It’s easy to be a cynic, but there is no doubt that despite our eyeballs being inundated with tens of thousands of ads every day, we still all watch this game and actively pay attention—even look forward to—the commercials. It’s that one magical day a year for brands used to the exact opposite every other day on the calendar. This past year was a weird one, not the Super Bowl’s first, but you’d never really know it watching these ads. Not a mask in sight. Social distance . . . huh? Ah well, chalk it up to the fine art of escapism and a very real desire to avoid having made … [Read more...] about The best Super Bowl ad of 2021 (and 5 really bad ones)

advertisement advertisement advertisement I’ve spent hours marveling at the secret love letter pocket in Chanel’s iconic flap bag and the eccentric tiger head on the clasp of Gucci’s Dionysus bag—and spent more money than I care to admit on the purses in my closet. I’m slightly embarrassed about my fixation with these objects, which ultimately amount to receptacles for keys and lip balm. That’s why I was so intrigued by an exhibit at London’s Victoria and Albert Museum that explores the history of humans’ obsession with bags. advertisement advertisement Bags: Inside Out features handbags going back to the 16th century, from traveling trunks to carriers for wartime gas masks to the first-ever Hermès Birkin. It’s eye candy for bag lovers such as me, but it also tells the story of how people have ventured further and further from their homes over the centuries, requiring containers to hold their … [Read more...] about When men carried handbags: The history of an iconic accessory
