This time sequence illustrates a comparison of champagne being poured in the traditional method (left) and like beer (right) as seen with an infrared video camera.
There's nothing like the distinctive "pop" of the uncorking of a bottle of bubbly to create a sense of celebration. Whether it's Dom Perignon or a $10 sparkling wine, bubbles add pizazz.
Sparkling-wine lovers sometimes point to the glittering streams of tiny bubbles as an important attribute. Why? Well, tiny bubbles are a sign of age, explains French chemist Gerard Liger-Belair, author of Uncorked: The Science of Champagne.
Superstorm Sandy is what most people will remember from the 2012 Atlantic hurricane season. But Sandy was just one of 10 hurricanes this year — a hurricane season that was both busy and strange.
Late summer is when the hurricane season usually gets busy. But Greg Jenkins, a professor of atmospheric science at Howard University, says this year was different.

Global health advocates often argue that the tropical diseases that plague many countries, such as malaria and dengue, can be conquered simply with more money for health care – namely medicines and vaccines.
Photographer Freya Najade journeys into the weird sci-fi world of Europe's agricultural production. In one cow-milking facility she visited, "two people are needed to milk twice a day 300 cows," she writes.

Apple Tree, 2011: Modern apple growers use apple varieties that are grafted onto Dwarfing Rootstocks. Developed at a research station in the U.K., these ... trees need less water and less space than traditional apple trees, which makes high density planting possible. The fruits are more accessible and easier to pick, because the trees are smaller.

Tomatoes I, 2012: In order to have total control over the nutrients and the irrigation, tomatoes are planted in sterile material such as rock wool and not in soil. By doing so, the tomatoes are, according to the growers, less likely infected by diseases, a smaller amount of pesticide is needed and the yield can be increased.

Lettuce, 2011: Lettuce is grown in a stacking system to provide a maximum use of space. Plants grow inside of plastic trays without soil. A conveyor belt is moving the plants to ensure they get all round sunlight. The whole growing process is computer controlled.

Cress, 2011: Cress, tomatoes, cucumbers, or lettuce are grown in closed systems just with LED lights. There is no sunlight and no direct exchange of air with the outside. Day and night, summer and winter stop existing. Humans are able to determine the shape, taste and color of plants and fruits. They can be grown anywhere from the desert to inside of restaurants and supermarkets.

Eggplants, 2012: A computer manages precisely the irrigation, the nutrients given to the plants and also the climate inside the greenhouse. Automatically windows open, sunscreens move, and waste, water and nutrients are collected, purified, and recycled.

Tomatoes II, 2011: In order to consume locally grown tomatoes in ... the U.K. or Germany, the tomatoes need to be produced in heated greenhouses. ... To produce in more sustainable ways and to keep the cost of energy low, the greenhouse above is heated by the waste heat from a nearby nuclear power station.

Strawberries II, 2012: Strawberry crops are grown on tabletop-raised beds. The tabletop system makes it easier to pick the fruits and eases the weed and pest control. A leaf and sap analysis determines the nutrient's compound, which is fed with the irrigation water. To accelerate the growth of the plants, growers above add CO2 from a close-by Shell refinery.

Milking Robot I, 2012: One milking robot milks three times per day, 60 cows. The cows are in a stable, in which they can move around freely. They can use the robot whenever they need to. No human needs to be present.

Mushrooms, 2012: To allow an all-year-round production of mushrooms and to increase the yield, mushrooms are grown in a microclimate inside growing rooms. A stacking system maximizes the production per square meter.

Chicken, 2011: Since the mid-1990s the consumption of chicken has increased by 75 percent worldwide. Chicken are often reared in barns. One chicken barn has the capacity to rear 50,000 chickens.
We all have an inkling of how our food is grown these days, but increasingly we don't really know what it looks like. You'd probably recognize a tomato plant or a cornfield — but these photos offer a perspective that a lot of us haven't seen.
I'm Michel Martin, and this is TELL ME MORE, from NPR News. Coming up, are you invited to any parties for Kwanzaa, which is going on now? If the answer is yes, you're not alone. If the answer is no, you're not alone, either. We'll ask just how widely observed is this inspired-by-Africa, made-in-America celebration.

In time for New Year's Eve, Science Friday examines the chemical reactions that transpire in fluted glassware. Ira Flatow and Richard Zare, a chemist at Stanford University, pore over the science of bubbles — from how to keep that open champagne fizzy (forget the cork) to why beer tastes better from a glass rather than a bottle.

In A Man of Misconceptions: The Life of an Eccentric in an Age of Change, John Glassie writes of 17th-century Jesuit priest and scientist Athanasius Kircher, a renaissance man who studied magnetism, Mount Vesuvius, even the blood of plague victims. The only problem? His theories were often wrong.

Did you know that the human overbite may have evolved after people began using forks and knives? In Consider the Fork, author Bee Wilson traces how kitchen tools--from knives to pots to gas stoves--have changed over time, and how they have influenced what, and how, we eat.
