2 . Aron Ralston was a pretty normal guy, but he always had an extremely adventurous desire to travel and see the world. During his childhood, his family moved to Denver, Colorado, a place offering many opportunities to climb mountains, explore, and eventually become the adventurer he’d always wanted to be. Back in 2003, Ralston was climbing in the remote, mountainous area of Southwestern Utah, when the unthinkable happened: Aron got stuck in a crevice (裂缝) in the rocks and pinned by a big stone that weighed over 360 kilograms. The weight of the rock crushed his arm, and he was pinned by it. Aron took photos of his bad situation (which was going to get a lot worse), hoping rescue teams (救援队) would know where he was and came to remove the rock so that he could get out and home safe.

But rescuers never came. Aron waited for them for days till he lost his hope. He knew he had to do something. He was 18 meters above the floor of the valley where he was pinned in, and he had a pocketknife. He made what must have been one of the most difficult decisions of his life: to cut his own arm in order to survive. Aron cut the lower part of his arm off, having to wrench (扭动) his forearm against the big stone to break the bones, and then got himself down to the bottom of the valley, where he would begin to walk and search for help. Luckily, help arrived in the form of a helicopter (直升机) that spotted him, covered in blood. Aron had tied off the wound to keep himself from bleeding to death pretty successfully and would eventually make it out alive.

Ralston went on to become an inspiring speaker and continued to travel and climb mountains—he didn’t let an incident that forced him to cut his own arm off, stop him from doing what he really loved.

3 . In habitats across the planet, animals periodically drop everything to walk, fly or swim to a new place. Some animals such as whales and geese learn migration paths by following their parents. Others, including small songbirds, gain the distance and direction of their migration within their genetic code. And some animals use a combination of genetics and culture to guide their migration.

Another group of migrators does not quite fit either model, and researchers have only recently started to figure out how they find their way. The Cory’s shearwater is an oceangoing seabird that migrates over the Atlantic every year. The young do not migrate with their parents, so culture cannot explain their journeys. And the exact paths vary wildly from individual to individual, making genetics equally unlikely.

Cory’s shearwaters are long-lived, rarely producing young successfully before age nine. This leaves an opening for learning and practice to develop their migration patterns. Researchers call this the “exploration-refinement”, and until now it has been hypothetical (假设的) because of difficulties in tracking migratory animals’ movements.

But a team of researchers has done that by attaching small geolocators to more than 150 of the birds aged four to nine. They found that younger birds traveled longer distances, for longer periods, and had more diverse paths than older birds. “We finally have evidence of the ‘exploration-refinement’ for migratory birds,” says Letizia Campioni, who led the study. Younger Cory’s shearwaters are able to fly just as fast as the adults——but they do not, suggesting that the young do more exploring, which gradually fades as they mature and settle into a preferred course.

“Although it may seem less efficient than other strategies, exploration refinement could be beneficial to birds and other organisms in a rapidly changing world due to unpredictable man-made changes,” says Barbara Frei. “It might be safer to repeat a behavior that was recently successful than to rely on patterns that were perfected long ago but might no longer be safe.”

4 . Food festivals are a common occurrence in the UK and take place in all sorts of places and at all sorts of times. Whatever your taste, there’s a food festival to match — no matter how specialized.

1. Meatopia

This three-day, London-based festival takes place at the end of August and is a meat lover’s paradise. In addition to a range of legally sourced meat products, from juicy burgers to tender steaks, attendees can listen to live music, watch butchery demonstrations, and attend informal meat-based workshops.

2. The National Honey Show

If you have a sweet tooth, then it could be that the National Honey Show, which started in 1921 and is the largest event of its kind, is the place for you to be. This three-day event attracts many local entries who showcase their sweet golden honey, some of which is sold globally.

3. The Orange Sauce Festival

Have you heard about a festival that is devoted only to orange sauce? Held in Cumbria, this sweet, fragrant festival has been running for 3 years. What attracts people most is a competition to find the best homemade orange sauce. There are thousands of participants from over 30 different countries across the globe, bringing their local snacks to share here.

4. The Ginger and Spice Festival

If you’d prefer something with a little more kick to it, then you could attend The Ginger (姜) and Spice Festival held in Market Drayton. Unlike other food festivals, it celebrates its town’s historic connection to Robert Clive, who returned from India with ginger. Because of this, they specialize in baking gingerbread, but also sell a range of traditional spices from mild to hot.

5 . Friends always ask why I, a middle-aged woman with no athletic (运动) talent (天赋), travel to perilous places — the jungles (丛林) of Thailand or Borneo, for example, where the water is often unsafe and the food risky; places with infectious diseases, poisonous snakes and the wildest animals.

I never know how to answer. Nine years ago I suffered a stroke (中风). To prevent another stroke, my doctors told me, I’d have to take dangerously high levels of blood thinner (血液稀释剂) for the rest of my life and any travel would be risky (冒险的).

I had to think about what was important to me: family, of course, and friends. But then what? No matter how many times I thought about it, I could not be happy without travel. Then I had to decide how I might manage the risk.

The first real test of my travel courage came nine months after my stroke when I joined my husband, Jack, on a business trip to China. After we’d toured the remains of a Tang dynasty temple on a high mountain, Jack wanted to ride down on a toboggan (长雪橇).

Before the stroke it would’ve seemed like fun. But now? I hesitated. My mental klaxon (高音喇叭) screamed warnings about the consequences of a cut, a fall, and a crash. Then, gaining confidence from who knew where, I lowered myself carefully into the toboggan, which marked my adventure (冒险) travel come back.

In the years since then, I’ve traveled about twenty-five percent of the time. Through it all, my lucks held out — no deadly falls, no car accidents or serious infections. For me, adventure travel is a risk worth taking. Travel broadens my world and keeps me connected to nature. What’s more, saying “yes” to travel keeps me connected to myself.

6 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.

For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.

Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”

Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

10 . Experimenting with eggs

What can you do with eggs other than eat them?

Naked Eggs

What does an egg look like without its shell? You may be picturing the white and yolk in a bowl after cracking it, but that isn’t the only way to remove the shell.

Materials: 1 egg, white vinegar, a bowl, a spoon

Directions: Fill a bowl with one cup of vinegar. Add the egg to the bowl, and wait at least 24 hours. When you check it after a day, you’ll notice some bubbles on the egg and a residue(残留物)in the water. Use the spoon to gently remove the egg from the bowl. Remove the old vinegar, and add a cup of fresh vinegar. Return the egg to the bowl, and wait another 24 hours. When you remove the egg this time, the shell should completely disappear.

Walking on Eggshells

Can Eggs hold the weight of your entire body?

Materials: six cartons(硬纸盒)of eggs, a garbage bag

Directions: Place the garbage bag on the floor to make any necessary clean up easier. Place the cartons of eggs into two rows of three. Make sure all the eggs are pointing in the same direction-either all pointy end up or all rounded end up. Step onto the first carton of eggs carefully. If you’re careful, you will succeed. Eggs are actually incredibly strong. The arch shape at the top and the bottom of the egg allows pressure to be distributed evenly over the egg.
