Description

Agriculture, or farming, is the oldest form of biotechnology. All the farmed plants and animals that we eat today, including cows, pigs, chickens, potatoes, wheat, corn, potatoes, tomatoes, rice, and many more, were developed thousands of years ago by farmers who practiced selective breeding of wild plants and animals. Modern science has adjusted this heritage of crop plants and livestock animals, but has not added anything really new to it. In the last century, technology has changed...

Ancient Roman Cosmetic Unearthed

In 2004 archaeologists in London found a pot with a lid containing a Roman beauty cream. The pot has been dated to the middle of the second century ce. An analysis of the cream showed that it was made of refined animal fat (probably from a cow or sheep), starch, and tin oxide. Although the Romans had traditionally used lead acetate as the coloring agent in their face creams, this cream contained tin oxide, probably from the ancient Cornish tin industry in western England. Unlike lead, tin had...

Eurofresh Farms Produce Hydroponic Tomatoes

Various fruits and flowers without the use of soil. In 1937, Gericke created the word hydroponics from two Greek words hydro (water) and ponos (labor). Although his way of performing hydroponics was considered too difficult for commercial farming, his work is still considered the foundation for all types of hydroponics. In the late 1940s, American horticulturists Robert B. Withrow and Alice P. Withrow, of Purdue University, designed a practical hydroponic system. The U.S. and British militaries...

Current Issues

The growing demand for new and unique varieties of wine has led wine-makers to introduce more advanced wine-making methods. They use improved fermentation techniques, as well as more hightech equipment. But there is another, more controversial method for improving wine quality. Some wine-makers are altering the DNA (deoxyribonucleic acid, the molecule in cells that carries the genetic information) of yeast to change the way it reacts with sugars during the fermentation process. Genetically...

Silk Making Goats

Why would scientists focus on goats to make spider's silk Because goats already contain the basic machinery for producing the silk proteins in their milk. Plus, a goat can make silk proteins in much larger quantities than a spider can. A single goat can produce about 1,000 quarts 950 liters of milk per year. Each quart can contain between one and ten grams of spider's silk, a significant amount considering one gram can stretch 9,000 yards 8,200 meters . of silk. To produce larger amounts,...

What Are The Current Issues Beekeepers Face

Beekeepers face at least two serious problems in maintaining their hives. Many diseases occur when bees are placed in hives more crowded than their natural environment. Consequently, the bees are more likely to die. Fewer bees means fewer colonies of bees, which results in less honey produced and less crops pollinated. Also, the expensive equipment used for beekeeping can easily become contaminated. In many cases, such equipment must be destroyed when contamination cannot be removed. Because of...
