Do your feet sometimes smell rotten? Do you wish you could toss out your shoes and start with a new pair? We make jokes about smelly feet, but smell and feet have a very different relationship among some insects. Take butterflies. Have you ever watched a butterfly flit over a plant, gently touch its feet to a leaf, and then fly on to the next leaf? That butterfly isn’t being picky about where to land. It’s hunting for the right kind of leaf for laying its eggs. It’s “smelling” the leaf with its feet! Actually, we need to qualify that statement a bit. Some writers will say the insect is “smelling” the leaf while others may write that it’s “tasting” the leaf. Smelling and tasting are forms of “chemoreception,” or sensing of chemicals. Smell usually refers to sensing from a distance while tasting generally means actually touching the nerve cells that sense a chemical. We humans have cells in our noses that send messages to our brains about chemicals in the air. We call that our sense of smell. We have cells on our tongues that sense chemicals dissolved in liquid in our mouths. That’s taste. That butterfly doesn’t have a nose, and its mouth is a long tube for sucking up nectar from flowers. Its chemoreceptors are elsewhere, like on its feet, around its mouth, and on its antennae. Most butterflies lay their eggs on the plants that the hatched caterpillars will eat. Some species are very specific about what plants their young can feed on. Take the postman butterfly, which lives in Central and South America. Its caterpillars can only survive on certain species of passionflower vines. Other species are poisonous to their offspring. The female postman butterfly has dozens of special nerve cells on her feet called “gustatory sensilla.” Scientists think that when she touches gently down on a leaf, these cells can sense chemicals there that would be poisonous to her caterpillars. She avoids laying eggs on those leaves. But when she finds a plant that will nourish her young, she’ll alight and lay her eggs. Now take your shoes off and move your feet around on the floor. The only nerve endings on your feet are ones that sense touch. But then, you don’t need to be able to smell the ground you walk on. Imagine how gross it would be if your feet could smell the insides of your socks and shoes—yuck!  In these photographs taken through a microscope, you can see the sensory sensilla (arrow) on the feet of the female butterfly on the right, which the male on the left doesn't have. From PLoS Genet.

 A dog’s nose is 300 times more powerful than a human nose, so it’s no wonder that dogs use their incredibly advanced sense of smell to do some very important jobs. In Super Sniffers, Dorothy Hinshaw Patent explores the various ways specific dogs have put their super sniffing ability to use: from bedbug sniffers to explosive detectors to life-saving allergy detectors . . . and more. This dynamic photo-essay includes first-hand accounts from the people who work closely with these amazing dogs. For more information, click here.

She was 15 pounds below minimum weight for the Navy when she joined, but she had a mighty mind. Admiral Grace Hopper changed the Navy. And your world. She graduated from Vassar College in math and physics then took a doctorate from Yale in math. She joined the Navy in World War II because it needed mathematicians to build the massive machines that computed tables of distance, gun elevation, projectile weight, windage and other factors for precise naval gunnery. Almost immediately she saw something other mathematicians didn’t see: computers could talk. They weren’t just number crunchers to Grace. They could do much, much more if they were given a simple language that would bring the advantages of gigantic computing power and enormous data storage to common uses. While working on the early computers she developed a “compiler,” a kind of translating machine that turned plain-language needs into a set of mathematical commands that retrieved number data from storage banks, performed thousands or millions of math operations, and provided real-world answers. In 1959 she was crucial in devising the first broad-based computer language, COBOL (COmmon Business Oriented Language). It is the root of the many computer operating systems we use today. Then-Captain Grace worked with the National Bureau of Standards to develop self-testing capabilities so a computer could “de-bug” itself. She coined this word when she extracted a fried moth disrupting one of her computers. She led the Navy away from a few giant computers to interconnected, smaller, scattered computers, opening the door to the internet. You are reading plain language words from my small computer on your web-connected small computer. Thank you, Grace. In 1985, at 79, she was promoted to rear admiral of the United States Navy Reserve. She said, “The most important thing I've accomplished, other than building the compiler, is training young people. They come to me, you know, and say, 'Do you think we can do this?' I say, ‘Try it.’ And I back 'em up. They need that. I keep track of them as they get older and I stir 'em up at intervals so they don't forget to take chances.” She died in 1992 at 85. Admiral Grace Hopper received many awards and decorations but the Navy’s most sincere tribute came in 1996 when it named the guided missile cruiser DDG-70, USS Hopper. Naturally, its sailors call their ship “Amazing Grace.”
 Jan Adkins successfully tackles the art and science of 10,000 years of bridge building and imparts a lot of historical drama along the way. The process is given fascinating life in this accessible study, wonderfully illustrated by Jan Adkins himself. Ranging from ancient Rome to the present day, from simple log bridges to marvels of industrial technology, and from well-known landmarks to little-known feats of engineering and art, this book gives readers a new appreciation for that most familiar of structures, the bridge.

In pro football’s early days, there was no set way of determining the league champion. In 1921, the Buffalo (New York) All-Americans had the best record (8-0-2) in the American Professional Football Association. Runners-up were the Chicago Staleys, named for team sponsor A.E. Staley Starch Company, with a 7-1 mark. (The team would become the Bears the following year.) The Staleys’ only blemish was a 7-6 loss to Buffalo on Thanksgiving Day. Chicago player-owner George Halas lusted for revenge. He persuaded Buffalo owner Frank McNeil to travel to Chicago for a game the day after the All-Americans’ final game on December 3 in nearby Akron, Ohio. McNeil agreed, with one stipulation: the game would be an exhibition and not count in the final standings. The Buffalo players took an overnight train to Chicago after a hard-fought triumph. Still recovering from the rigors of that game and lack of sleep, the All-Americans lost to the Staleys 10-7. Halas saw an opportunity. He quickly scheduled two more games with other teams, winning one and tying the other. In his eyes, the results of those additional games meant his team was now 9-1-1, while Buffalo was 9-1-2 (tie games didn’t figure in the standings). Despite the seeming identical records between the two teams, Halas appealed to the other owners. He said his team deserved the league title on two grounds: the second game between Chicago and Buffalo was more important than the first, and his team had outscored Buffalo 16–14 in their two contests. The owners sided with Halas despite McNeil’s vehement protests that the second Chicago game was an exhibition. McNeil spent the rest of his life trying to overturn what he called the “Staley Swindle.” The league—now the National Football League (NFL)—decided that henceforth the season would have a definite ending date, though rejecting the idea of a championship game. In 1932 Chicago and the Portsmouth Spartans had identical records. The NFL sanctioned a game between them to determine the champion. Chicago won 9-0. The game attracted so much interest that the NFL split into East and West divisions, with a playoff between the division winners to crown the champion. That playoff has continued to the present day (though adding several rounds to determine the finalists). Super Bowl Sunday has become so important in the United States that many people (not entirely jokingly) have suggested making it a national holiday.

In 1804, President Thomas Jefferson sent Meriwether Lewis, William Clark, and a team of men on a vital mission to explore the wild, unmapped West. Lewis brought his dog along. According to journals kept by several of the explorers, the dog helped a lot. He retrieved animals that had been shot for food. He scared away grizzly bears, and a bull bison that charged into camp. The old journal pages are often hard to read, and this led to a misunderstanding of the dog's name. People thought that he was called Scannon. Not until 1985 did a historian carefully examine every mention of the dog. He found that Lewis had actually named the dog Seaman. The dog was a Newfoundland, a breed often kept on ships. They are great swimmers, and could save people from drowning. In the expedition's journals, Seaman was last mentioned in July, 1806, two months before the explorers returned from the West and reached the little town of St. Louis on the Mississippi River. After that, there is no word about the dog in letters or reports written by Lewis, Clark, or others. The mystery of what happened to Seaman was solved in the year 2000, thanks to the work of historian James Holberg. He had found a book, written in 1814 by historian Timothy Alden, which told of a little museum in Virginia. Alden found a dog collar displayed there that William Clark had given to the museum. On the collar were these words: "The greatest traveller of my species. My name is SEAMAN, the dog of captain Meriwether Lewis, whom I accompanied to the Pacifick ocean through the interior of the continent of North America." The collar was later destroyed by fire, but in his 1814 book Timothy Alden also wrote further details about Seaman. Historians report that after the expedition, Meriwether Lewis' life became one of failure and despair. In October 1809 he took his own life. Alden wrote that Seaman was there when Lewis was buried, and "refused to take every kind of food, which was offered to him, and actually pined away and died with grief upon his master's grave." People who know Newfoundland dogs say that this could be true, because these dogs are fiercely loyal to their owners. Unless historians find some new evidence, that is how the life of this great dog hero ended.
 The Lewis and Clark Expedition was the first American expedition to cross what is now the western portion of the United States, departing in May 1804, from near St. Louis on the Mississippi River, making their way westward through the continental divide to the Pacific coast. Seaman was along on every bit of the round trip expedition of over seven thousand miles. However, like the explorers, he traveled many of those miles on a keel boat or canoe--up the Missouri and other rivers, downstream to the Pacific Ocean, and then the return journey to St. Louis in 1806.  Laurence Pringle has written a book about Seaman. This richly detailed account of the Lewis and Clark expedition includes its planning, its adventures and discoveries, and its aftermath. With intriguing sidebars, historical illustrations, journal excerpts, and original art, this account of what became known as the Corps of Discovery features the remarkable dog that was the expedition's most unusual member.

Yes, they exist! At the height of the Roman inquisition in the late sixteenth, early seventeenth centuries, Michelangelo Merisi da Caravaggio ignored the rigid rules that guided what could be painted. Rather than follow the current style based on idealized human beings in ennobling religious stories, he used real people as models. More than that, he invented a genre based on daily life rather than on religious or historical stories. He taught people to see the holy in the everyday and the everyday in the holy. This alone was a tremendous act of rebellion and could have led to imprisonment, even death. Caravaggio did go to prison, many times, but not for the crime of pictorial heresy. His first arrest was for carrying a sword without a permit— yes, you needed a sword license then, much as you need a gun permit today. His second arrest happened when an officer stopped him for carrying a weapon. Though Caravaggio had the permit, he refused to show it. The third time he was spotted carrying his sword, he showed the permit. The officer thanked him, but Caravaggio couldn't resist cursing out the policeman, so he was arrested for insulting an officer. But the best arrest was for assault with a vegetable. This is the official deposition, taken 18 November 1599: It was around five in the afternoon and the aforesaid Caravaggio, along with some others, was eating in the Moor of the Magdalene where I work as a waiter. I brought him eight cooked artichokes, that is four in butter and four in oil and he asked me which were cooked in oil and which in butter. I told him that he could smell them and easily know which were cooked in butter and which were cooked in oil, and he got up in a fury and without saying a word, he took the plate from me and threw it in my face where it hit my cheek. You can still see the wound. And then he reached for his sword and he would have hit me with it, but I ran away and came right to this office to present my complaint. Caravaggio went on to be arrested many more times for more serious assaults, including murder. Now, though, he's not remembered as a criminal, but rather as an artistic genius who inspired generations of followers.   Judith Beheading Holofernes (1599–1602) is the first of several paintings in which Caravaggio chose to depict the dramatic and gory subject of decapitation. Wikimedia  Basket of Fruit, c. 1595–1596, oil on canvas. Caravaggio's realistic view of things is exemplified in this still life. The bowl is teetering on the edge of the table, some of the leaves are withered, and the apple in the front is far from perfect. Wikimedia  Marissa Moss's book Caravaggio:Painter on the Run tells a compelling story that humanizes Caravaggio while describing the political and social atmosphere in which he lived. Moss, Marissa.
