In agrarian(农业的), pre-industrial Europe,“you'd want to wake up early, start working with the sunrise, have a break to have the largest meal, and then you'd go back to work,”says Ken Albala, a professor of history at the University of the Pacific.“Later, at 5 or 6, you'd have a smaller supper.”

    This comfortable cycle, in which the rhythms of the day helped shape the rhythms of the meals, gave rise to the custom of the large midday meal, eaten with the extended family.“Meals are the foundation of the family,”says Carole Couniban, a professor at Millersville University in Pennsylvania, “so there was a very important interconnection between eating together and strengthening family ties.”

    Since industrialization, maintaining such a slow cultural metabolism has been much harder, with the long midday meal shrinking to whatever could be stuffed into a lunch bucket or bought at a food stand. Certainly, there were benefits. Modern techniques for producing and shipping food led to greater variety and quantity, including a tremendous increase in the amount of animal protein and dairy products available, making us more energetic than our ancestors.

    Yet plenty has been lost too, even in cultures that still live to eat. Take Italy. It's no secret that the Mediterranean diet is healthy, but it was also a joy to prepare and eat. Italians, says Counihan, traditionally began the day with a small meal. The big meal came at around 1 p.m. In between the midday meal and a late, smaller dinner came a small snack. Today, when time zones have less and less meaning, there is little tolerance for offices' closing for lunch, and worsening traffic in cities means workers can't make it home and back fast enough anyway. So the formerly small supper after sundown becomes the big meal of the day, the only one at which the family has a chance to get together.“The evening meal carries the full burden that used to be spread over two meals,”says Counihan.

    Ever get that feeling you're being watched? Well, if you're a dog-owner, you may have a point. Dogs are able to watch people's interactions with one another to determine who holds yummier treats, according to a new study. This study joins others that show dogs are good observers of human behaviors and feelings. It offers evidence that dogs use information not only from people's direct interactions with them, but also their interactions with one another.

    In the study, dogs watched a man ask two women for some of their corns. Both women gave the man corns when he asked, but in response to one woman, the man showed his enthusiasm and said the corns were so delicious. In response to the other woman, he gave the corns back and called them gross（in Spanish；the study was conducted in Argentina）. After these interactions, the man left and an assistant holding the dog let the dog go. While many dogs didn't approach either woman, the dogs that did have a preference tended to prefer the woman with the yummier(美味的) food.

    Other studies of dogs' people-watching ability have found dogs are able to tell the difference between happy and sad faces in their owners. They prefer people who give others food when asked over people who don't give others food. And in one study, dogs turned toward crying people more often than toward talking people.

    So how much do dogs really understand about the humans around them? That's not totally settled yet. In a strange twist to the Argentine study above, when the researchers tried an experiment in which they put two plates of corns on a table and had a man react to each plate, dogs didn't preferentially approach the tastier plate afterward. You could say dogs watch for the interaction between two persons, not just how a person reacts. Yet a previous study found dogs will choose boxes that people reacted to happily, but not boxes people reacted to with a disgusted face.

    Well, either way, you can be sure Fluffs is keeping an eye on you, to the best of her ability. The study was published in the journal PLOS One.

    My mom only had one eye. I hated her... she was such an embarrassment. My mom ran a small shop at a flea market. She collected little weeds and such to sell... anything for the money we needed she was such an embarrassment. There was this one day during elementary school.

I remember that it was field day, and my mom came. I was so embarrassed. How could she do this to me? I threw her a hateful look and ran out. The next day at school... "Your mom only has one eye?!" and they taunted me.

I wished that my mom would just disappear from this world so I said to my mom. "Why don't you just die?" My mom did not respond. I guess I felt a little bad, but at the same time, it felt good to think that I had said what I'd wanted to say all this time. Maybe it was because my mom hadn't punished me, but I didn't think that I had hurt her feelings very badly.

    That night... I woke up, and went to the kitchen to get a glass of water. My mom was crying there, so quietly, as if she was afraid that she might wake me. I hated my mother who was crying out of her one eye. So I told myself that I would grow up and become successful, because I hated my one-eyed mom and our desperate poverty.

Then I studied really hard. I left my mother and came to Seoul and studied, and got accepted in the Seoul University with all the confidence I had. Then, I got married. I bought a house of my own. Then I had kids, too. Now I'm living happily as a successful man. I like it here because it's a place that doesn't remind me of my mom.

This happiness was getting bigger and bigger, when someone unexpected came to see me "What?! Who's this?!" It was my mother... Still wither one eye. It felt as if the whole sky was falling apart on me. My little girl ran away, scared of my mom's eye.

And I asked her, "Who are you? I don't know you!!" as if I tried to make that real. I screamed at her "How dare you come to my house and scare my daughter! Get out of here now!!" And to this, my mother quietly answered, "oh, I'm so sorry. I may have gotten the wrong address," and she disappeared. Thank goodness... she doesn't recognize me. I was quite relieved. I told myself that I wasn't going to care, or think about this for the rest of my life.

    Then a wave of relief came upon me... one day, a letter regarding a school reunion came to my house. I lied to my wife saying that I was going on a business trip. After the reunion, I went down to the old shack, that I used to call a house, just out of curiosity there, I found my mother fallen on the cold ground. She had a piece of paper in her hand. It was a letter to me.

She wrote:

My son, I think my life has been long enough now. For you... I'm sorry that I only have one eye, and I was an embarrassment for you. You see, when you were very little, you got into an accident, and lost your eye. As a mother, I couldn't stand watching you having to grow up with only one eye… so I gave you mine... I was so proud of my son that was seeing a whole new world for me, in my place, with that eye. I was never upset at you for anything you did. The couple times that you were angry with me I thought to myself, ‘it's because he loves me.' I miss you so much. I love you. You mean the world to me. So I gave you mine. With all my love to you! Your mom.

My World Shattered. I hated the person who only lived for me. I cried for My Mother, I didn't know of any way that will make up for my worst deeds...

    Mike Miles hadn't had a stable job in years. He bounced around from one position to another, never sure when his last day would be. Sometimes, he lost a position with less than a day's notice. This wasn't due to a poor work ethic—from arriving early to staying late, Miles says he did everything he could to build a good relationship with employers. But because Miles had a criminal record, he was always cut loose when it came time to let staff go.

    It wasn't until October 2015, nearly a decade after his release from prison, that a cousin told Miles about Lancaster Food Company, a local business that focuses on hiring people released from prison. Hoping this would clear up what felt like a thick cloud of uncertainty over his future, Miles submitted an application. He got an interview, and he then began a new job.

    Miles' scenario is rare in Lancaster, where the poverty rate holds steady at 30%. This figure riled Charlie Crystle,  Lancaster's co-founder and CEO. Crystle was raised in Lancaster but left in 1986 to purse a college degree and later, a career in technology. He co-founded four tech companies, one of which sold for millions of dollars back in 2000.

    Crystle is skeptical that many of Lancaster's low-income residents can get started the way he did. He believes food production is a key way to meet former offenders who may lack a college degree. Lancaster produces products like bread. Nowadays the company is rapidly expanding; however, at just 16 full-time employees, including administration and owners, it doesn't lower the city's poverty rate.

    Crystle says he wants to inspire other companies to rethink their current practices and start conversations around minimum wage and employment opportunities for everyone, including ex-offenders. Dan Jurman, who chairs the city's Commission to Combat Poverty, believes that Crystle's business is a great way to make this happen. "None of us can handle these issues alone, " he said.

    Green tree ants are important builders in the rainforest. They're like the worker bees of the ant world. The native forest of Thala Beach Nature Reserve is the natural home of these insects.

    They climb all over the tree that contains their nest and protect it from enemies with great fierceness. The ants are often in the fruiting trees of Tropical North Queensland. When an animal tries to help themselves to some tasty fruit, they find themselves attacked by a powerful, frightening army of green tree ants! Their bite is not very painful but many ants attacking at the same time can be extremely uncomfortable.

    The nests are large and constructed by sticking the leaves at the end of branches together to create a home looking roughly like a globe. Most of the nest construction and weaving is conducted at night. A mature colony of green tree ants can hold as many as 100,000 to 500,000 workers and may include as many as 12 trees and contain as any as 150 nests. Green tree ant colonies have one queen and a colony can live up to eight years.

    However, the ants are so busy that they fail to spot a dishonest figure. There is a spider called the Salticid spider, or the jumping spider, as they are sometimes referred to, which has excellent eyesight and is only active during daylight, weaving a protective covering of silk to spend the night in. Interestingly, the Salticid spider does not look like a green tree ant. Instead, it chemically copies green tree ants' smell. Effectively pretending to be an ant, it goes into the green tree ants' nest, enters the nursery and feasts on their babies. Green tree ants don't have good eyesight and smell everything with their antennae (two long thin parts on an ant's head). Therefore, the ants think the spider is another ant and ignore its presence within the nest.

    Next time, as you wander around Thala's native forest, keep an eye out for these busy little creatures. Look up into the trees and you'll likely spot their nests.

    The fiddler crab (蟹) is a living clock. It indicates the time of day by the colour of its skin, which is dark by day and pale by night. The crabs changing colour follows a regular twenty-four hour plan that exactly matches the daily rhythm (节奏) of the sun.

    Does the crab actually keep time, or does its skin simply answer to the sun's rays, changing colour according to the amount of light strikes it? To find out, biologists kept crabs in a dark room for two months. Even without daylight, the crab's skin colour continued to change exactly on time.

    This characteristic(特性) probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies. After millions of years it has become completely regulated (受控制) inside the living body of the crab.

    The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day before. From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides (潮水). The crabs period of greatest darkening is exactly the time of low tide on the beach where it was cought!
