Red, White, but Rarely Blue — The Science of Fireworks Colors, Explained

In the earliest days of the United States, John Adams wrote to his wife Abigail about the celebration of independence, “It ought to be solemnized with Pomp and Parade, with Shews, Games, Sports, Guns, Bells, Bonfires, and Illuminations from one End of this Continent to the other from this Time forward forever more.” “Bonfires and illuminations” refer directly to what we know as pyrotechnics and firework displays. I’m a chemist and also president of Pyrotechnics Guild International, an organization that promotes the safe use of fireworks and using them here in the U.S. to celebrate Independence Day and other festivals throughout the year. As a chemist, and someone who leads demonstrations for chemistry students, I consider fireworks a great example of combustion reactions that produce colored fire. But the invention of colored fireworks is relatively recent and not all colors are easy to produce.

Historic US Railway Stations Are Getting a New Lease on Life

Englishman “Gobsmacked” After Finding His Wife’s Childhood Notes in a Thrift Store Children’s Novel

An English book collector was riffling through a children’s novel he’d picked up from a thrift shop when he stumbled upon a happy surprise: notes his wife had written 50 years ago as a child. A collector of around 50 novels by the late Enid Blyton — a bestselling children’s author who penned an estimated 800 books over four decades — 67-year-old Steve Mills told the BBC he was “completely gobsmacked” by the discovery. He was going through some new additions when he found the writings from Karen, 60, in a copy of The Naughtiest Girl Again, which had been donated by her mother in the 1970s. It somehow ended up in a thrift store in Rayleigh — a town in the U.K. that’s more than 160 miles away from where Karen grew up in Staffordshire. Steve, a retired civil servant who has loved Blyton’s books since he was a child, told SWNS, “We’ve taken it as one of the universe’s strange coincidences.”

Scientists Harness “Pharaoh’s Curse” Toxic Fungus to Create an Anti-Cancer Drug

When archaeologists opened King Tutankhamun’s tomb in Egypt in the 1920s, the unexpected deaths among members of the excavation team that followed sparked rumors of a “pharaoh’s curse.” Decades later, doctors speculated that fungal spores may have contributed to those deaths. Now, researchers at the University of Pennsylvania have found a new way to harness that fungus: using it to treat leukemia. Detailing their findings in the journal Nature Chemical Biology, the scientists isolated a new class of molecules from Aspergillus flavus, a toxic crop fungus linked to infamous deaths following the excavations of ancient tombs. After the chemicals were modified, the resulting compound showed “promising” cancer-killing properties that rivaled FDA-approved drugs when tested against leukemia cells, according to a press release, opening new frontiers for fungal medicines. “Nature has given us this incredible pharmacy,” senior author Sherry Gao said. “It’s up to us to uncover its secrets. As engineers, we’re excited to keep exploring, learning from nature, and using that knowledge to design better solutions.”

Stop the “Good” vs “Bad” Snap Judgments and Watch Your World Become More Interesting

How many times have you used the words “good” or “bad” today? From checking your weather app to monitoring the progress you’ve made on your to-do list, to scrolling through social media, opportunities to make snap evaluations abound. And the more you sort things into these categories, the more instinctive making these judgments becomes. You may find yourself filtering everything that comes your way in terms of “good” or “bad.” A dark cloud triggers “bad,” a social media post of baby animals triggers “good,” a news story about a political scuffle triggers “bad.” Whether you think something is good or bad, or worthy of a like or not, is an important piece of information. But if that categorization is the only thing that’s on your mind, the only lens through which you interpret the world, you’ll miss out on a lot. I’m a philosopher who specializes in happiness, well-being and the good life. I study how one’s state of mind influences one’s experiences of the world. In my recent book “The Art of the Interesting,” I explore the ways the evaluative perspective squashes your ability to experience psychological richness and other positive dimensions of life. The more you instinctively react with a “good” or a “bad,” the less of the world you take in. You’ll be less likely to engage your mind, exercise curiosity and have interesting experiences.

How Positive Self-Talk Boosts Mental Health, and Strategies for Putting It Into Practice

“I should’ve known better.”  “C’mon, you’ve got this!” “It’s just my luck.” There’s a decent chance you’ve heard these phrases before — right inside your very own head. That’s because they’re common examples of self-talk, the internal dialogue we have with ourselves throughout the day. At certain times it’s unconscious and at others it’s obvious,
