Can technology stop the body from aging? It may sound like something out of a science fiction film, but it may be a reality someday. A company named Calico is partnering with universities to explore this puzzle. So far, the company has focused on looking at Integrated Stress Response (ISR), the process by which the body reacts to stress, a known trigger for aging. Another company called Immusoft is working to program our own cells to treat diseases associated with age. By inserting DNA into cells, the company hopes to help the body produce needed proteins on its own.

Match the problems with their solutions.

• Solution

• Calico is performing research on ISR.

• People get diseases as they age.

• Immusoft is performing research with DNA.

• Stress causes people to age.

Every year, the Girl Scouts of the USA earn around five hundred million dollars by selling cookies. The idea began with the Muskogee, Oklahoma, chapter in 1917. The scouts needed to raise money, so they sold baked goods out of high school cafeterias. Cookie sales soon spread to other chapters around the country. But in 1943 the scouts hit a snag: they couldn't fill cookie orders. America had entered World War II, and many baking supplies weren't available. Sugar and other items were saved for military use. The scouts responded by finding other ways to make money, such as selling Girl Scout calendars.

Match the problems with their solutions.

A. The Girl Scouts couldn't fill cookie orders.

B. In 1917, the Girl Scouts wanted to raise money.

• Solution

• The Girl Scouts sold calendars.

• A

• The Girl Scouts sold baked goods from cafeterias.

When people swim in the ocean, they may fret about getting stung by jellyfish. Fortunately, most stings are mild and can be treated on the spot. Since stingers are extremely sticky, people need to check for any left in the skin and quickly remove them. Experts recommend scraping them off with a credit card or other piece of plastic. Movement causes the venom to spread. To prevent the spread of toxins, people should stay still. Painful swelling and itching can be treated with hydrocortisone cream.

Match the problems with their solutions.

• Jellyfish toxins may spread.

• Problem

• Solution

• People should stay still.

• Jellyfish stings may cause discomfort.

• People should apply hydrocortisone cream.

Sourdough bread begins with a starter—a mix of flour, water, and wild yeast. Starters can be used again and again, but they require special care. For instance, sourdough has to be kept warm. During the California Gold Rush, miners found a clever way to make sure their starters stayed warm on chilly nights: they cuddled them. In addition, starters must be fed regularly, like pets. What if you wanted to travel and didn't have someone to feed your starter? People in Sweden found the answer: sourdough hotels. In 2012, Stockholm's Urban Deli began boarding starters for travelers.

Match the problems with their solutions.

A. Sourdough starter must be fed.

B. Sourdough starter needs to be protected from the cold.

• B

• Miners in California snuggled with their starters.

• A

• Sourdough hotels opened in Sweden.

The Inuit are a group of native people from the Arctic tundra of North America and Greenland. For thousands of years, traditional Inuit life was shaped by their harsh environment. The tundra is so cold that trees can't grow there. The Inuit people worked around this scarcity of building materials. In the winter, they built igloos, round houses made from blocks of snow. In the summer, they built huts from animal skins stretched over a frame. Most plants can't grow in the tundra, either, which made large-scale agriculture impossible. Instead, the traditional Inuit diet was mostly meat, such as fish, seals, and whales.

Match the problems with their solutions.

• Solution

• Problem

• No trees grow in the tundra.

• The traditional Inuit diet mainly consisted of meat.

• Almost no plants grow in the tundra.

• Traditional Inuit homes were made of snow or animal skins.

In 1969, four music promoters were planning a music festival in Woodstock, New York. However, the town refused to grant permission for the event. Luckily for the promoters, a dairy farmer in the area came to the rescue and allowed the festival to take place on his land. When the festival opened on August 15, more than four hundred thousand people crashed the gates to get in. The promoters couldn't deal with so many people, so they opened the festival to everyone, free of charge. Thus, the legendary Woodstock Music Festival was born.

Match the problems with their solutions.

• The promoters couldn't control the crowd

• Problem

• The town didn't grant permission.

• The festival was opened to all.

• Solution

• The festival was held at a dairy farm.

In 1936, Germany constructed the Hindenburg, an airship composed of a metal framework surrounding gas-filled bags. It needed to meet strict weight limits, so chairs were made of lightweight aluminum. Designers wanted to fill the airship with helium, which doesn't burn. There was one issue, though. At the time, only the United States produced helium. Americans feared Germany would use the gas for military purposes, so they refused to sell it. Engineers responded by redesigning the Hindenburg to use flammable hydrogen—a dangerous mistake. In 1937, a hydrogen leak combined with a spark of static electricity, and the airship burst into flames.

Match the problems with their solutions.

• Some furnishings were made of aluminum.

• The U.S. wouldn't sell helium to Germany.

• Solution

• Problem

• The Hindenburg was redesigned.

• The Hindenburg had strict weight limits.

Though the number of giant pandas has increased in recent years, the bears still face several challenges. One issue is that the panda diet is made up of bamboo, which is difficult to digest. Much of what they eat is passed as waste. To get all the nutrients they need, pandas must eat twenty to forty pounds of bamboo each day. The biggest crisis pandas face, though, is loss of habitat. Chinese cities are growing fast and are pushing pandas out of their homes. Thankfully, the Chinese government is taking action by establishing parks and reserves where pandas are protected.

Match the problems with their solutions.

• Solution

• Much of what pandas eat passes through as waste.

• The Chinese government provides reserves

• Problem

• Pandas eat large quantities of food.

• Pandas are losing their natural habitats.

Today, Jesse Owens is remembered as a world-class track-and-field athlete. But his path to stardom was long and full of hardship. Owens represented the United States at the 1936 Berlin Olympic Games, where he earned four gold medals. But when he returned home, President Franklin D. Roosevelt never met with Owens to congratulate him, contrary to tradition. In 1976, the mistreatment was finally addressed when President Gerald Ford awarded Owens the Presidential Medal of Freedom. Sadly, despite his success, Owens struggled to make money. To earn a living, he had to participate in stunt races against dogs, horses, and motorcycles.

Match the problems with their solutions.

A. Owens participated in stunt races.

B. Owens was awarded the Medal of Freedom in 1976.

C. Owens failed to get the recognition he deserved.

D. Owens's Olympic wins failed to result in financial success.

Is low-cost space travel possible? Jeff Bezos thinks so. In 2015, his company Blue Origin launched New Shepard, a reusable spaceship. New Shepard's design allows the ship to return to Earth after flights. This is an improvement on traditional spacecraft, which are incapable of reuse. Blue Origin might also have a low-cost alternative to traditional rocket fuel. Their proposed BE-4 engine runs on liquid oxygen and methane, a natural gas, rather than on liquid oxygen and kerosene. Methane is less likely than kerosene to clog engine fuel lines, which would make BE-4 engines last longer than existing designs.

Match the problems with their solutions.

• Blue Origin launched New Shepard.

• Traditional engines can get clogged.

• Solution

• Problem

• Blue Origin developed the BE-4.

• Traditional spacecraft cannot be reused
