It has enabled individuals to communicate real-time news, ideas, and experiences without relying entirely on traditional media outlets. This has resulted in a more diversified and decentralized information ecology, allowing users to rapidly access a vast range of opinions and breaking news.

POLITICAL AND SOCIAL MOVEMENTS: Social media has become a driving force behind political and social transformation. It has provided a platform for marginalized voices, allowing activists and grassroots groups to raise awareness, organize protests, and mobilize support for a variety of issues. Examples include the Arab Spring, #BlackLivesMatter, and #MeToo campaigns.

BUSINESS AND MARKETING: Social media has altered how businesses function and sell their goods and services. It has paved the way for new forms of advertising, customer engagement, and market research. Social media networks provide tailored advertising choices, allowing firms to efficiently contact specific groups.

Measuring the intelligence of animals can be difficult because there are so many indicators, including the ability to learn new things, the ability to solve puzzles, the use of tools, and self-awareness. Determining the most intelligent animals can lead to debate—and some surprises.

trictly speaking, humans Smans are the smartest animals on Earth—at least according to human standards.

We are adept at all the tasks we’ve established as intelligence indicators, and we have used our smarts to do everything from improving our quality of life as a species and building great societies to achieving scientific advancements such as sending people to the Moon. But what about the millions of other animal species? How do we rate them?

Consider the octopus. At first glance, it might not appear to be very smart, yet studies have found that certain types of cephalopods possess great curiosity and problem-solving abilities. In one experiment, an octopus figured out how to unCONTINUES ON PAGE 6

screw a container lid to retrieve the tasty morsel inside. In another, an octopus learned to recognize human individuals, responding positively to a friendly person while ignoring a person who acted impersonally. The recognition of individuals is a sign of intelligence also shared by pigeons.

One might assume that chimpanzees—one of our closest genetic relatives—would rate highly on our intelligence scale, and they do.

In a 2007 study, researchers gave adult chimps, adolescent chimps, and college students the same cognitive test, which involved remembering where nine numbers were located on a touchscreen monitor after seeing the numbers for less than a second. The adult chimpanzees and the college students scored about the same.

In one test, goats had to use their teeth to pull a rope down, activating a lever they then had to lift with their mouths. A total of 9 out of 12 goats were able to figure out the contraption after four tries, and the majority still remembered how to work the device 10 months later. Many animals are effective at using tools, including chimpanzees, which commonly use sticks to extract ants and termite larvae.

WHAT IS ANIMAL-ASSISTED OR PET THERAPY?

going to the hospiItalmagine to have surgery and being able to take your favorite pet with you.

Animal-assisted therapy, also known as pet therapy, uses dogs and other animals, including horses, to help people as they recover from physical and mental health conditions. The companionship of the animal has proven benefits in both medical and psychological work.

While that scenario is unlikely to happen due to hospital protocols, you can, in reality, have a dog, cat or even a horse help with your recovery. How? Through animalassisted therapy. If you are an animal lover, you can bring joy to people facing their most challenging situations by becoming a therapy animal trainer or handler. You can train your own pet, or you can get a pet specifically to train as a therapy animal. Either way, you will bring joy to people as you help speed up healing and increase support for people in treatment settings. If you think that working with therapy animals is a good fit for your passions and skills, then it’s time to take a closer look at what animal-assisted therapy is and how to become a trainer or handler.

HOW DOES ANIMAL-ASSISTED THERAPY WORK?

Animals bring comfort to people, and spending time with animals can make healing faster and easier. Animal-assisted therapy allows a trained service or therapy animal to come to an appointment or visit someone in the hospital.

When someone is dealing with a serious medical or mental health condition, they face a significant amount of stress. That stress can hinder their healing.

slowed breathing, and interaction with welcoming animals actually boosts the immune system as well. Some researchers have found an increase in salivatory immunoglobulin A, which indicates a healthy immune system function, after people spend time petting a dog for less than 20 minutes. The release of oxytocin impacts the immune system and increases the pain threshold, helping people heal more quickly.

SKILLS IMPROVEMENT A third benefit of animalassisted therapy is improved skills in therapies of all types. In physical therapy that requires exercise that is sometimes uncomfortable, participants find themselves more motivated to participate in therapy after interacting with a pet. The increased pain threshold that comes with the oxytocin release can also motivate people to push harder in their therapy programs.

mon. Everyone’s doing "C’ it." So why shouldn’t you?

If you're interested in sports, you might hang out with the "jocks." If you're interested in music, you spend time with others who enjoy music.

It’s almost expected that you will experience peer pressure frequently throughout your teen years.

You belong to that group and feel secure when you are part of it. The group identifies who you are and what you’re about.

Say you're invited to a party where you know there will be alcohol or drugs. A friend decides to cut class.

But what if people in "your group" start doing things that are wrong, hurtful, or even illegal? And what if these same people are your friends?

Someone offers you a cigarette. Or friends talk about having sex with their boyfriends or girlfriends.

This is what we refer to as peer pressure -- the pressure to conform to the behaviors, attitudes, and personal habits of "the group."

• How do you respond? • Are you tempted to follow their examples? • Or can you stand strong in your own belief system? At some point, everyone has the desire to fit into a group.

It’s almost expected that you will experience peer pressure frequently throughout your teen years.

In many cases, there are serious risks involved. Let’s look at some common situations. Think about what you would do in each: "My friends told me about this party at this abandoned warehouse on Friday night. I know there’s going to be alcohol involved, and someone there is supposed to bring CONTINUES ON PAGE 12

some marijuana. I don’t drink or do drugs, but I don’t want them to think I’m a loser."

For example, if you’re active in sports, your teammates probably pressure you to be the best you can be. If you’re on the track team, you pace yourself with the fastest runner, because you know it will make you better. If you’re striving for good grades, you compare your scores to those at the top of the list. If you’re in the band, and there are musicians better than you, you are pressured into striving to be the best musician you can be.

"This older guy at church that I really like smokes cigarettes. He keeps offering them to me and my friends. Last week my best friend Stacy smoked one with him." "My girlfriend keeps pleading with me to go all the way with her. She says 'everybody’s having sex' these days, but I want to save myself for marriage. All of my friends have had sex, and I really like my girlfriend. I don’t want her to think I’m some kind of prude." In all of these cases, your decision about how to handle the peer pressure can have great consequences: What if the cops bust the party at the warehouse and you are arrested? How would your parents react when the police call them? How would an arrest affect your college admissions or your reputation? As for the second example, it goes without saying how bad smoking is for your health, including the risks of lung disease, heart disease, and cancer. It's all too easy to get hooked on cigarettes. Speaking of long-term effects, you really have to think through what you’d do in the third example. Having sex even one time could leave your girlfriend pregnant. You’d have to change your life from student ... to father. And what if you got a sexually transmitted disease? How would you cope if you found out you had gonorrhea or HIV? Friends and family increase the risk of children becoming

ASSESSING THE RISKS OF PEER PRESSURE As you see, there can be serious risks involved with peer pressure. Unfortunately, most teenagers are not applauded for their logical thought processes.

At some point, every person must stand alone, even when tempted by friends and other peers. You know what is right. You know what is wrong. And only you can decide which path to take. Ask almost anyone who has "been there, done that" about peer pressure. Most people have gone with the crowd at some point in their teenage lives, and they’ve had to live with the consequences. You'll likely hear that bowing to peer pressure wasn't worth it. Now is your chance to believe in yourself and to stand alone at times, if you need to. When faced with group demands, assess the risks ahead of time. If you are uncomfortable doing something, don't be afraid to decline the invitation with a ''no, thanks.'' Learning to stand up for yourself and your beliefs and to look ahead to consequences of your actions are important steps in becoming a responsible adult. ◙ SOURCE: REACH OUT PARENTS

One theory is that less sunlight during fall and winter leads to the brain making less serotonin, a chemical linked to brain pathways that regulate mood.

Seasonal depression is a mood disorder that happens every year at the same time.

When nerve cell pathways in the brain that regulate mood don't work the way they should, the result can be feelings of depression, along with symptoms of fatigue and weight gain.

A rare form of seasonal depression, known as "summer depression," begins in late spring or early summer and ends in fall. In general, though, seasonal affective disorder starts in fall or winter and ends in spring or early summer. SAD may affect 11 million people in the U.S. each year, and 25 million more may have a milder form called the winter blues.

determine the New Seven Wonders of the World. Given that the original Seven Wonders list was compiled in the 2nd century BCE—and that only one entrant is still standing (the Pyramids of Giza)—it seemed time for an update. And people around the world apparently agreed, as more than 100 million votes were cast on the Internet or by text messaging.

GREAT WALL OF CHINA

Great might be an understatement. One of the world’s largest buildingconstruction projects, the Great Wall of China is widely thought to be about 5,500 miles (8,850 km) long; a disputed Chinese study, however, claims the length is 13,170 miles (21,200 km). Work began in the 7th century BCE and continued for two millennia. Although called a “wall,” the structure actually features two parallel walls for lengthy stretches. In addition, watchtowers and barracks dot the bulwark. One not-so-great thing about the wall, however, was its effectiveness. Although it was built to prevent invasions and raids, the wall largely failed to provide actual security. Instead, scholars have noted that it served more as “political propaganda.”

Chichén Itzá is a Mayan city on the Yucatán Peninsula in Mexico, which flourished in the 9th and 10th centuries CE.

PETRA

The ancient city of Petra, Jordan, is located in a remote valley, nestled among sandstone mountains and cliffs. It was purported to be one of the places where Moses struck a rock and water gushed forth. Later the Nabataeans, an Arab tribe, made it their capital, and during this time it flourished, becoming an important trade center, especially for spices. Noted carvers, the Nabataeans chiseled dwellings, temples, and tombs into the sandstone, which changed color with the shifting sun. In addition, they

constructed a water system that allowed for lush gardens and farming. At its height, Petra reportedly had a population of 30,000. The city began to decline, however, as trade routes shifted. A major earthquake in 363 CE caused more difficulty, and after another tremor hit in 551, Petra was gradually abandoned. Although rediscovered in 1912, it was largely ignored by archaeologists until the late 20th century, and many questions remain about the city.

MACHU PICCHU This Incan site near Cuzco, Peru, was “discovered” in 1911 by Hiram Bingham, who believed it was Vilcabamba, a secret Incan stronghold used during the 16th-century rebellion against Spanish rule. Although that claim was later disproved, the purpose of Machu Picchu has confounded scholars. Bingham believed it was home to the “Virgins of the Sun,” women who lived in convents under a vow of chastity.

TAJ MAHAL This mausoleum complex in Agra, India, is regarded as one of the world’s most iconic monuments and is perhaps the finest example of Mughal architecture. It was built by Emperor Shah Jahān (reigned 1628–58) to honor his wife Mumtāz Maḥal (“Chosen One of the Palace”), who died in 1631 giving birth to their 14th child. It took about 22 years and 20,000 workers to construct the complex, which in-

Others think that it was likely a pilgrimage site, while some believe it was a royal retreat. (One thing it apparently should not be is the site of a beer commercial. In 2000 a crane being used for such an ad fell and cracked a monument.) What is known is that Machu Picchu is one of the few major pre-Columbian ruins found nearly intact. Despite its relative isolation high in the Andes Mountains, it features agricultural terraces, plazas, residential areas, and temples.

Somewhat disconcertingly, the statue has often been struck by lightning, and in 2014 the tip of Jesus’s right thumb was The resulting monument damaged during a storm. Christ the Redeemer, a colossal statue of Jesus, stands atop Mount Corcovado in Rio de Janeiro.
