Attempts at making animal chimeras in the lab began decades earlier. In 1984, researchers at the Institute of Animal Physiology in Cambridge, England, reported that they had created goat-sheep chimeras by mixing embryos from the two species. More recently, news leaked in 2019 that scientists had made the first embryos that were part human and […]

“V. vulnificus is only active at a temperature that’s above 13 degrees Celsius, and then it becomes more prevalent up until the temperature reaches 30 degrees Celsius, which is 86 Fahrenheit,” says Karen Knee, who is an associate professor and water-quality expert at American University and an open-water swimmer accustomed to ocean conditions. “I was […]

Obesity may lead to heart failure in a few different ways. Too much weight gain can cause inflammation, including in the heart. That inflammation can make the heart stiffer and increase the risk of failure. Greater body weight also means more blood volume, which can increase the pressure inside the heart and cause congestion. High […]

Robert Bonnie, the under secretary for agriculture for farm production and conservation at the USDA, says that criticisms of the PCSC aren’t entirely fair. “These are pilots. We’re actually going to go out and try some things. We don’t have all the information we need,” he says. He points out that a number of the […]

When the history of Burning Man 2023 is written, it’s likely Diplo and Chris Rock deciding to trudge for five miles out of the festival site will be recorded as the point the fun stopped. The musician and actor were forced to abandon their campsite by foot as torrential rains turned the Nevada desert, which […]

At first glance, the grit crust could seem like a routine example of what researchers call a biological soil crust, or “biocrust”—a community of coexisting bacteria, fungi, algae, and other microorganisms that caps the soil in coherent sheets. Around 12 percent of Earth’s land is covered by biocrusts. Ecologists often refer to these colonies as […]

For three years, the US Centers for Disease Control and Prevention (CDC) has issued complicated—and occasionally contradictory—guidance on when you should wear a mask, depending on whether you’re inside, outside, vaccinated, or not vaccinated. But no matter how cautious you are, if you’re a parent, there is one significant way you’re probably getting sick: Your […]

“The movement is still strong,” said Shafer. “It just seemed like a lot of parasites were attaching themselves to it. You have the movement, and then a lot of people that were trying to make money off it.” Shafer defines a tiny house as one in which “all the space was used efficiently and nothing […]

Buried lines may be immune to the wind, but they’re not indestructible. Earthquakes can jostle that piping, and water can also intrude. On Maui, any efforts to underground lines would have to contend with rising sea levels that could eat at the soil supporting the pipes. “It all comes down to this overarching problem, that […]

Chemicals can also be harmful because of the specific combinations they are used in, Muncke adds—something known as “mixture toxicity.” It thus makes little sense to regulate the amounts of individual substances in cups, she says, because you still can’t be sure what impact they’ll have. Improving recycling practices would be a logical step in […]
