Tattooing is an art that humans have been practicing for millennia. While 32 percent of adults in the United States have at least one, many of the inks in the United States today used to decorate people's skin are more of a motley mixture than a precise blend, a new study has found.Kelli Moseman, a chemistry researcher at Binghamton University in New York, and colleagues, analyzed more than 50 tattoo inks from nine different brands used in the US after noticing that some inks they had used in previous studies contained…

In April, a dozen years after a federal agency classified formaldehyde a human carcinogen, the Food and Drug Administration is tentatively scheduled to unveil a proposal to consider banning the chemical in hair-straightening products.The move comes at a time of rising alarm among researchers over the health effects of hair straighteners, products widely used by and heavily marketed to Black women. But advocates and scientists say the proposed regulation would do far too little, in addition to being far too late.“The fact…

No matter how much or how little experience we have in the kitchen, many of us have at least a handful of culinary secrets. It might be as simple as remembering to season our food well. Or how adding just a bit of butter or garlic can make a huge difference to the flavor profile of a dish. The more we’re willing to experiment, the more we can learn. The friendly everyday cooks of the popular r/Cooking subreddit spilled the beans about the fancy ingredients that they’ve personally found to be extremely worth the…

Volkswagen’s CFO Arno Antlitz said Europe’s largest automaker has “all the ingredients” for success as the US auto industry shifts to electric. Despite this, VW is seeing reluctance for its EVs in Europe and potentially in the US as well. Volkswagen gears up for North American EV transition In an interview with Bloomberg Television Wednesday, Antilitz explained VW has what it takes to grow in the US as the buyers transition to EVs. Last April, Volkswagen announced its first North American…

According to a study released on December 21, scientists analysed organic compounds called polycyclic aromatic hydrocarbons (PAHs) — which were extracted from the Ryugu asteroid and Murchison meteorite. They found that certain are PAHs "likely to be formed in the cold areas of space between stars, rather than in hot regions near stars as was previously thought", Curtin University said in a report. Scientists from Curtin's WA-Organic and Isotope…

"You get what you pay for" isn't an adage we can always rely upon. A US study has found more than one-third of a selection of sports supplements bought online don't contain key ingredients the label says they should.Pieter Cohen, a clinician-researcher at Cambridge Health Alliance and Harvard Medical School in Cambridge, Massachusetts, and colleagues ordered 57 sports supplements to analyze their contents.Each product's label claimed the supplement contained one of five botanical compounds with purported…

Just four years ago, the movement to ban police departments from using face recognition in the US was riding high. By the end of 2020, around 18 cities had enacted restrictive laws, and lawmakers proposed a pause on the federal government’s use of it.  In the years since, that effort has slowed to a halt. Some local bans have even been partially repealed, and today, few seriously believe that a federal ban could pass in the foreseeable future. Right now in the US, facial recognition regulations are trapped in political…

This might not be a surprise, since I'm almost constantly going on about batteries—If you want to read more on the topic, we've got loads to choose from on the site. You can start here, here or here. Batteries are going to transform transportation and could also be key in storing renewables like wind or solar power for times when those resources aren’t available. So in a way, they’re a central technology for the two sectors responsible for the biggest share of emissions: energy and transportation.  And if you want to…

NASA’s JWST space telescope has observed a 10,000-kilometer-long plume of water vapor jetting into space from Saturn’s moon Enceladus—the largest spray ever detected from the icy world, which is just one-seventh the diameter of Earth’s Moon. Planetary scientists view Enceladus as a prime target in the search for extraterrestrial life because beneath its icy crust the moon houses a salty ocean—a good medium for the ingredients of life to mix. Vented from fractures…
