If you’re enjoying some tasty food today that has at least one ingredient that was farmed somewhere, you probably owe a little thanks to earthworms. How is it that these detritivores – literally dirt eaters – turn what humans find inedible into beloved compost? After the biology and physics of swallowing and “chewing”, like us it’s all chemistry for digestion. But earthworms have an extra enzyme that allows them to munch through cellulose, the ultimate fiber of that makes tree bark a non-starter in human diets. Yet all this powerful chemistry means not everyone sees earthworms as the greatest creature to crawl – find out all the dirt in this video. http://web.1.c2.audiovideoweb.com/1c2web3536/Reactions-Earths_Little_Garbage_People.mp4 Wednesday, 19 April 2017 11:00:00 -0400 1:59 Reactions, Science, Chemistry, Education, American Chemical Society, health, environment, Food, agriculture, earthworms, farming, plants no Reactions Bicycle day's just around the corner, but it's not what you think.

As humans learned to farm, we arranged plants outside in horizontal fields, and invented irrigation and fertilizer to grow bumper crops. But with modern technology and farmers’ cleverness, we can now stack those fields vertically, just as we stacked housing to make apartment buildings. Moving plants indoors has many benefits: Plants are not at the mercy of weather, less wilderness is cleared for farmland, and it’s easier to control the runoff of fertilizer and pesticides. But the choice of lighting can make or break the cost of a vertical farm and affect how long it might take for urban agriculture to blossom. http://web.1.c2.audiovideoweb.com/1c2web3536/Reaction-Is_this_the_Farm_of_the_Future.mp4 Tuesday, 27 February 2017 11:00:00 -0400 1:59 Reactions, Science, Chemistry, Education, American Chemical Society, health, environment, farming, food science no Reactions Cats love catnip, but that’s not why the catnip plant makes the kitty drug.

Alchemists tirelessly sought the recipe for the Philosophers' Stone -- a substance that could turn any base metal into pure gold. The Philosopher's Stone would give its user untold wealth and power, so alchemists were known to operate under total secrecy. They worked in codes and symbols -- to reserve their great knowledge for only those who were deemed deserving. Instead of the chemical formulas used today, alchemists created elaborate, fantastic illustrations of dragons, warriors, and monsters to represent the chemical experiments they carried out. Centuries passed, and many historical alchemical texts and images remain undeciphered. Luckily for the history of science, we have brilliant minds like Larry Principe of Johns Hopkins University. In our latest video, we take a look at Larry's work - digging deep into ancient manuscripts and texts, trying to find clues and cues as to what it was that alchemists really were up to. In addition to an enormous book collection in his office, Larry has a lab hidden away where he performs ancient alchemical experiments, helping to set the record straight on the history and development of alchemy.

Eggshells consist of calcium carbonate, the same chemical that makes up marble chips. But try to dye a white marble chip. Nope -- won't work! So what is it that makes eggshells dye-friendly?

Prior to becoming Monnell's Director, Gary Beauchamp studied the sweet taste receptor genes of cats in the late 1970s. At the Philadelphia Zoo, he gave lions, tigers, cheetahs and housecats two different types of water—sugar water and regular water. The cats showed no preference to the sugar water, suggesting a physiological difference between other mammals, such as humans, monkeys, and dogs.

•Chocolate may improve your mood, and not just because of its delicious flavor. Chocolate contains a number of chemicals that inhibit the breakdown of the neurotransmitter anandamide -- sometimes called "the molecule of bliss" -- which can block feelings of pain and depression. 
•According to an article from the Journal of Agricultural and Food Chemistry, the naturally occurring polyphenols in cocoa ― the key ingredient in chocolate ― boost levels of HDL, commonly known as the "good cholesterol." http://web.1.c2.audiovideoweb.com/1c2web3536/Bytesize_Science-Five_sweet_facts_about_the_chemistry_of_chocolate.mp4 Mon, 11 February 2013 11:00:00 -0400 3:19 ‪ ‬Bytesize Science, Chemistry, Education, Science Teacher, American Chemical Society, ACS, Holidays, ‪sweet‬s, ‪the chemistry of chocolate‬, Valentine's Day, Singles Awareness Day no Bytesize Science The video tracks formation of snowflakes from their origins in bits of dust in clouds that become droplets of water falling to Earth. When the droplets cool, six crystal faces form because water molecules bond in hexagonal networks when they freeze. It explains that ice crystals grow fastest at the corners between the faces, fostering development of the six branches that exist in most snowflakes. As snowflakes continue to develop, the branches can spread, grow long and pointy, or branch off into new arms. As each snowflake rises and falls through warmer and cooler air, it thus develops its own distinctive shape. http://web.1.c2.audiovideoweb.com/1c2web3536/Bytesize_Science-The_Chemistry_of_Snowflakes.mp4 Wed, 17 December 2012 11:00:00 -0400 6:12 ‪ ‬Bytesize Science, Chemistry, Education, Science Teacher, American Chemical Society, ACS, Snowflakes, Happy Holidays, winter season, snow, Christmas no Bytesize Science The video explains that the calorie content of food was determined in the late 1800s by chemist Wilbur O. Atwater. Atwater built a four by eight foot device called a respiration calorimeter, which was big enough to allow a person to step into it! It measured the amount of heat they released, the amount of oxygen they consumed and the carbon dioxide they gave off after eating a variety of foods.

Using this device, Atwater was able to measure the precise amount of energy contained in thousands of food items. He found that carbohydrates and proteins were worth 4 Calories per gram and fats about 9 Calories per gram.

But these historical images can be difficult to conserve, especially since each type of photograph requires a different preservation technique. While two photos could look very similar, they may differ chemically in dramatic ways. This is where photo conservation scientists like Art Kaplan at the Getty Conservation Institute come into the picture. Art spends his days studying different styles of photographs, their materials and the chemistry that gave life to still life in the early days of photography. His office is loaded with drawers of photographic samples, scientific instruments and a clear passion for frozen history. In our latest video, Art explains the developmental processes of several types of photographs including daguerreotypes, ambrotypes and tintypes. http://web.1.c2.audiovideoweb.com/1c2web3536/Bytesize_Science-A_Brief_History_of_Photography-Innovations_in_Chemistry.mp4 Wed, 14 November 2012 11:00:00 -0400 5:02 ‪ Bytesize Science‬, Chemistry, Education, Science Teacher, ‪History of Photography‬, Getty Conservation Institute, daguerreotypes, ambrotypes and tintypes, American Chemical Society, ACS no Bytesize Science Imagine a submarine.

Chemiluminescence is at the heart of how glow sticks (as well as fireflies) give off their otherworldly light. When scientists first tried to make their own glowing material in the 1960s, they realized they needed two components. The first is a molecule that lights up when excited, and the second is an energy source to excite the first molecule. But that's not all the chemistry involved - every unique glow stick color requires a different glowing molecule.
