During World War I,countless soldiers were able to return home because of the protection provided by the heavy helmet.

A young officer in the U. S. Army witnessed the effectiveness of the helmet and realized its potential in a postwar industrial world. In 1919, Edward W.Bullard returned from the war to the family business,which was founded by his father Edward D. Bullard in 1898. He began developing ideas for affordable safety helmets that would protect miners. While the metal helmet was ideal for wartime conditions, it was not suitable for the mining industry. It was too big for miners to work underground and move through tight places. Plus, the cost was high So he chose to use a kind of heavy duck canvas（帆布), which was then formed to fit the human head with steam, thus named Hard Boiled Hat.He attached leather brims（帽檐） to it, and painted it black, so it would hold up to everyday wear in dirty, dangerous mines.

The hard hat was the first commercially available head protection device. Now worn by millions of workers, Bullard's hard hat revolutionized the safety-product industry, earning him a spot in the National Inventors Hall of Fame. At first, wearing a hard hat was a choice, not a requirement. That changed, however, during construction of the Hoover Dam, along the Colorado River in 1931. For the first time, employers required workers to wear hard hats.Now headquartered in Cynthiana, Kentucky,E. D. Bullard Co. is a leading manufacturer of high-quality personal protective equipment and systems worldwide, including a wide range of safety helmets. Edward W. Bullard has an eye on the future.The company plans to introduce a newline of Bullard hard hats for the industrial market.

Can staying up late make you fat? A growing body of research has suggested that poor sleep quality is linked to an increased risk of obesity (肥胖症). But a new study found that it’s not the sleep loss that leads to obesity, but rather that overweight can cause poor sleep.The researchers discovered their findings in a very small worm, called C.elegans.

Study co-author David Raizen stressed that while these findings in worms may not translate directly to humans, C. elegans offers a good model for studying humans' sleep. Like all other animals that have nervous systems, they need sleep. But unlike humans, who have complex neural circuitry (神经回路) and are difficult to study, a C. elegans has only 302 nerve cells，one of which scientists know for certain is a sleep regulator.

In humans, people who get fewer than six hours of sleep per night are more likely to be obese. Moreover, starvation in humans, fruit flies, and worms has been shown to affect sleep, indicating that it is regulated, at least in part, by nutrient availability. However, the way in which sleeping and eating work in tandem (协同地) has remained unclear.

The researchers genetically changed C.elegans to “turn off" a nerve cell that controls sleep. These worms could still eat, breathe, and reproduce, but they lost their ability to sleep.With this nerve cell turned off,the researchers saw a severe drop in ATP levels, which is the body's energy currency. “That suggests that sleep is an attempt to conserve energy; it's not actually causing the loss of energy,"Raizen explained.

The researchers knocked out the KIN-29 gene to create sleepless worms, and the mutant (突变的) C.elegans accumulated much fat. They assumed that the KIN-29 mutants did not sleep is because they were unable to release their fat.To test this guess, the researchers again controlled the KIN-29 mutant worms,this time expressing a chemical substance that freed their fat. With that operation,the worms were again able to sleep.

Washing soda is a kind of chemical that can be used to remove stubborn stains from laundry. It also has many uses around the house. And it is used in a range of industrial applications as well. Washing soda should not be confused with washing powder, which is a powdered soap used as a detergent.     16    

Washing soda (Na₂CO₃) is also known as sodium carbonate. It is a salt of carbonic acid, a chemical that produces a wide range of salts known as carbonates. One common source of washing soda is the ashes of plants.     17     Sodium carbonate can also be created from what is known as table salt.

    18     It helps remove a range of stains, and unlike other detergents, washing soda does not usually stain. It is also used to treat hard water, so that clothing will come out clean, without any stain. Sodium carbonate is also used to help fabric have a longer lasting color.

Around the house, washing soda can be used to wash things like coffee machines and bathroom floors which may accumulate mineral deposits as a result of exposure to hard water. It can also be used for other touch cleaning jobs like cleaning the stove.     19     That’s because it can damage your skin.

Many markets carry washing soda, typically with other laundry products. After purchasing washing soda and bringing it home, store it cautiously. Sodium carbonate can be dangerous in large quantities.     20     So keep washing soda out of the reach of children and pets, and clearly label the container to indicate its harm.
