In 2009, Theodore Gray blew minds with his gorgeously photographed book, The Elements: A Visual Exploration of Every Known Atom in the Universe, which sold over a million copies. Five years later, Gray has created this book, which describes what happens when elements are snapped together to make molecules, and the result is a masterpiece (thanks in no small part to Nick Mann’s drool-inducing photographs). Gray organizes the book by categories of molecules — inorganic, organic, acids, bases, soaps, solvents, oils, sweeteners, and other common substances — highlighting their similarities and differences. Suddenly, the physical world makes a lot more sense.

These young folks have a lot of fun throwing a big hunk of sodium into a pond. If you're impatient, forward to the boom at :53.
Our best wishes and deep respect to psychedelic pioneer and maverick chemist Alexander "Sasha" Shulgin who is preparing for his final trip on Earth; he is "surrounded by love and a lot of laughter," his wife and research partner Ann Shulgin posted on Facebook:

Stanford bioengineer Manu Prakash and his colleagues devised a $5 "chemistry set" that can be programmed to mix various reactants by punching holes in a paper tape and feeding it through the handheld device. Prakash says he was inspired by a hand-cranked music box. This latest device for what Prakash calls "frugal science" is on the heels of his amazing 50-cent folding microscope that I blogged previously.

Sheryl Canter's post on the science of cast-iron pan seasoning is a fascinating and practical tale of flaxseed and kitchen chemistry. It's a long process -- you need to season the pan six or so times, each time taking a couple of hours -- but the science is sound and the proof is in the hard, nonstick coating your pan will have when you're done.

The bad news: Massive piles of pig manure are foaming up and then exploding
and nobody is really sure why. The worse news: The only solution (other than, you know, not raising so many pigs all together) is to feed the pigs more antibiotics — a practice that contributes to antibiotic resistance.

Mother Jones has an interesting story about several start-ups trying to create fake meat, dairy, and eggs
that are not only sustainable, but appetizing ... even to people who aren't already committed vegans. It's a story about business and ethics, but it's also a story about chemistry and food engineering. As a meat eater who does enjoy seitan, I'm intrigued.
Last week, a Swiss investigation found evidence to support the idea that Yasser Arafat was poisoned with polonium-210 — a radioactive element that's safe to carry around in a container, but causes unstoppable death if swallowed. NPR sat down with Deborah Blum, a science writer who specializes in the chemistry of poisonings, to talk about what makes polonium-210 a particularly handy way to off somebody
and why it's so hard to bring a polonium poisoner to justice.
In the 1960s, Russian scientists discovered a new form of water that congealed at room temperature, froze at -40, and wouldn't boil no matter the temperature. For a few brief years, "polywater" was a scientific rage — the subject of pop culture craziness, Cold War research races, and CIA interrogations. At Slate, Joseph Stromberg tells the story of polywater and explains why, despite all that hype, most of us have never heard of it today
The synthetic (or man-made) elements are the ones with silly-sounding names, found along the bottom of the periodic table — Einsteinium and Nobelium, Livermorium and Mendelevium, and more. Unlike the rest of the elements, you won't find them just hanging out in nature. They have to be created in a laboratory, and they only exist for a limited amount of time — some no more than milliseconds. Though new ones have been discovered/created as recently as 2010, the 1950s and 60s were sort of a heyday of synthetic elements, with different laboratories locked in a race to find the niftiest new things first.
During that time, researchers at Lawrence Berkeley National Lab made a film strip reenacting their own 1955 discovery of the element Mendelevium. The film lay forgotten in storage for 60 years until it was recently uncovered and restored by retired physicist Claude Lyneis. Originally just a silent sequence showing real Mendelevium discoverers Al Ghiorso, Bernard Harvey, Gregory Choppin, and Stanley Thompson demonstrating how they'd found the 101st element, the film has been updated with narration and sound effects and is a pretty cool explanation of where synthetic elements come from.
We talk about computer modeling a lot in the context of climate science — powerful algorithms that help scientists get a better idea of how climate systems work, how they spin off into weather, and how the systems and the weather are altered by both nature and humans. But modeling plays a huge role in other sciences, as well. In fact, on the flip side of the climate change coin, modeling is an essential part of designing better solar cells to turn energy from the Sun into useable electricity. If we ever do master the art of artificial photosynthesis, we'll have the three men who just won this year's Nobel Prize for Chemistry to thank.
Back in the 1970s, Martin Karplus of Université de Strasbourg, France and Harvard University, Michael Levitt of Stanford, and Arieh Warshel of USC, were instrumental in constructing the first computer models capable of predicting the effects of chemical reactions — including ones that happen far too quickly to be observed. Today, their work touches the daily lives of chemists all over the world, doing research from solar cell design to drug development.

From a National Geographic story by Mollie Bloudoff-Indelicato, the quote of the week:
“I lift up the animal’s tail,” said Joanne Crawford, a wildlife ecologist at Southern Illinois University, “and I’m like, ‘Get down there, and stick your nose near its bum. People think I’m nuts,” she added. “I tell them, ‘Oh, but it’s beavers; it smells really good.’”
Crawford is talking about castoreum, a naturally occurring anal secretion found in beavers. The furry animals use it to mark their territory. We humans, however, have also found uses for castoreum. Most notably, as an ingredient in vanilla-flavored and vanilla-scented products.
