A Mayan city lost in the dense jungle of southern Mexico has been revealed. The discovery occurred in the southeastern state of Campeche, and archaeologists have named it Valeriana, after a nearby freshwater lagoon. “The larger of Valeriana’s two monumental precincts has all the hallmarks of a classic Mayan political capital: enclosed plazas connected by…
So overall, the weight loss we see from these high-quality studies is very small, and mostly with no change in body composition. The studies included people with different diseases, and most were from the Middle East or the Indian subcontinent. So we can’t be certain we would see this effect in people with other health…
“I see [technology] as important in democratizing the process and demedicalizing the process,” says Nitschke, adding the Sarco is not reliant on heavily restricted drugs to operate. “So all of those issues are ways to make the process more equitable.” In Switzerland, where the Sarco was used, Nitschke’s arguments about access to assisted suicide are…
This story originally appeared on WIRED Italia and has been translated from Italian. “We are witnessing the beginning of a new era, as the internet was in the 1980s. Today access to space is still something for the few, but just as in computing, in a few years prices will come down. Everyone should indulge…
After Milton made landfall as a Category 3 hurricane in western Florida last week, some residents who evacuated the area are now returning to discover water damage in their homes. And they may soon find something else: mold. Mold can begin to grow as soon as 24 to 48 hours after moisture exposure. And Florida’s…
This developing field, known as aerial electroreception, opens up a new dimension of the natural world. “I find it absolutely fascinating,” said Anna Dornhaus, a behavioral ecologist at the University of Arizona who was not involved with the work. “This whole field, studying electrostatic interactions between living animals, has the potential to uncover things that…
You can see that it’s limited by the materials in the tires and track (captured by the frictional coefficent) and the gravitational field (so, what planet you’re on). Notice that the mass has canceled out. It doesn’t matter if you have a more massive vehicle. Yes, you get more friction, but it’s also harder to…
Student nutrition directors like Primer say the foundation that allows schools to experiment with new recipes is California’s universal free lunch program. She notes that, when school lunch is free, students are more likely to actually try and enjoy it: “Free food plus good food equals a participation meal increase every time.” Nora Stewart, the…
In fact, bubble bursts caused by wave energy can release 100,000 metric tons of microplastics into the atmosphere each year. Since dolphins and other marine mammals breathe at the water’s surface, they may be especially vulnerable to exposure. Where there are more people, there is usually more plastic. But for the tiny plastic particles floating…
To study the cell membranes of deep-sea animals, the biochemist Itay Budin (center) joined forces with marine biologists Steve Haddock (right) and Jacob Winnikoff (left). Photographs: From left: Tamrynn Clegg; Geoffroy Tobe; John Lee “They are looking into an area that, to a large degree, has not been explored,” said Sol Gruner, who researches molecular…
