Solar Powered Hornets?
by Dan Bailey in Smells Like Science
The phrase “solar powered hornets” may conjure terrifying images of a futuristic, stinging swarm of eco-conscious, half-insect, half-machine hornets. But these hornets might already exist. And don’t worry, they’re just normal hornets. Researchers have recently discovered that the Oriental hornet may be capable of harvesting energy from sunlight.... Read more »

Field Notes From a Maya Ruin
by Dan Bailey in Smells Like Science
The ruins of La Milpa lie at the top of a steep, slippery path that winds upward from a rutted dirt road in Belize’s Rio Bravo Conservation Area. After scrambling up this path for the first time, I found myself beneath a dense jungle canopy, in the midst of a shadowy ruin. Unlike many other large Maya sites, La Milpa has not been uncovered, reconstructed, and opened to tourists. Instead, it remains shrouded in a thick layer of dirt and a thousand years’ worth of jungle growth. As you........ Read more »

Daily Aspirin May Reduce Risk of Cancer Death
by Dan Bailey in Smells Like Science
Aspirin knows how to multitask. It was originally developed more than a century ago as a pain reliever, but it was soon discovered that it also reduces fever and fights inflammation. In the last 30 years it was found that a daily low dose of aspirin reduces the risk of heart attacks and strokes. And now a new study suggests that aspirin taken over an extended time period reduces the risk of death from a variety of solid tumor cancers, including colorectal, lung, esophageal, and gastrointestinal ........

Ether and the Discovery of Anesthesia
by Dan Bailey in Smells Like Science
There is an unusual, and mostly forgotten monument in a shaded area at the edge of the Boston Public Garden in downtown Boston. It was completed in 1868, and, like many other monuments built during the 19th century, it features classical statuary, granite columns, and biblical inscriptions. But unlike any other monument in the world, it memorializes a drug. The inscription on the front face of the monument reads: “To commemorate that the inhaling of ether causes insensibility to pain.

Looking to the Past in Search of New Drugs
by Dan Bailey in Smells Like Science
Scientists have often looked to nature in the quest for new drugs to treat everything from cancer to infectious diseases, and they’ve found effective drugs in unexpected places – sea sponges, the bark of the Pacific yew tree, a throat swab from a chicken. But archaeologist Patrick McGovern and an interdisciplinary group of researchers at the University of Pennsylvania are using a different approach: they’re looking to the past in search of new drugs....

A Language of Light from a Tiny Molecule
by Dan Bailey in Smells Like Science
As a little kid I was an expert firefly catcher. But these days, I’m clearly out of practice. I spent a good half-hour the other night unsuccessfully chasing down fireflies to photograph for this post. As soon as they stopped glowing they receded into the darkness, becoming nearly invisible. Eventually I gave up the hunt and watched the seemingly random flickers of light coming from the fireflies all around me. What looks at first glance like random sparks and flashes in the night, is actu........ Read more »

The Psychology of Killing and the Origins of War
by Dan Bailey in Smells Like Science
Has warfare been handed down to us through millions of years of evolution? Is it part of who we are as a species? At the heart of this question is whether humans have a natural capacity to kill other humans. Some social scientists have concluded that evolution has in fact left us with this unfortunate ability.
Primatologist Richard Wrangham, a major proponent of this idea, developed the “Imbalance of Power Hypothesis” to explain how evolution could produce a propensity for warfare........ Read more »

DNA Reveals the Story of a Mysterious Group of Ancient Humans
by Dan Bailey in Smells Like Science
At the end of the last ice age modern humans were migrating out of Africa, Neanderthals roamed Europe, and new research has shown that a previously unknown population of ancient humans lived in Asia. All that remains of this mysterious group is a section of finger bone and a wisdom tooth. The group has been named the Denisovans after Denisova Cave in Siberia where the tooth and bone segment were found. A few months ago researchers completed an analysis of mitochondrial DNA from the finger bone a........ Read more »

Chimpanzee Warfare?
by Dan Bailey in Smells Like Science
The Chimpanzees who live at the Ngogo site deep within Uganda’s Kibale National Park spend their days foraging and feeding, wrestling and playing, grooming and socializing. But every 10 to 14 days a group of males gathers and moves away from the rest of the group. They form a single-file line as they walk purposefully toward the edge of their territory, eventually striking out into the territory of a neighboring group of chimpanzees. They move in atypical silence, scanning the underbrush and ........ Read more »

Clues to Copper's Past
by Dan Bailey in Smells Like Science
There are billions of miles of copper wire strung across the globe, buried beneath cities, spanning even the most remote landscapes, winding through our homes, our computers, and our cell phones. Although some of this global tangle of wires has lately been replaced by fiber-optic cable and wireless signals, we still depend on copper and its ‘wandering’ S electron to light our cities, power our appliances, and transmit the electrical signals we use to communicate. While the importance........ Read more »

The Vasa Resurrected
by Dan Bailey in Smells Like Science
After the Vasa was salvaged from the bottom of Stockholm harbor nearly intact in 1961 and towed to a dry dock, archaeologists were some of the first people to board the resurrected ship. They squeezed through the Vasa’s cramped quarters and slogged through three-foot-deep mud on the lower decks, searching for artifacts. They quickly began to uncover thousands of objects: coins, bowls, cups, elegant furniture, a board game, a butter cask containing 333-year-old butter. Like a nautical Pompe........ Read more »

Cities Before They Were Cities
by Dan Bailey in Smells Like Science
There’s an engraved marker at the top of Copp’s Hill in the North End of Boston not far from my apartment. The marker explains that the hill provided 17th-century colonists with a respite from the “three great annoyances, of woolves, rattle-snakes, and musketos.” Mosquitos may not be so far-fetched, but rattlesnakes and wolves in the North End of Boston? It’s hard to imagine. But ever since I discovered this marker, I’ve often wondered what the area looked lik........ Read more »

Apple Pie, Hold the Apples
by Dan Bailey in Smells Like Science
There aren’t many foods that are as closely tied to American identity as apple pie. And Americans love apple pie so much that, at times, we’ve felt compelled to make it even when we don’t have any apples. I’ve heard about a recipe for apple-less apple pie from a number of people over the years, but I’ve never talked to anyone who’s actually eaten it. So this past weekend, I decided to give it a try.

Honey Bees, Whiskey, and Juicy Fruit Gum

For a blog called Smells Like Science, you might have noticed that I haven’t written much about smelly science. That all changes here as I get to the bottom of the “Juicy Fruit: which fruit does it taste like?” debate. Plus, what do Juicy Fruit Gum and honey bees have in common?... Read more »
