A new concept vehicle, Pod was introduced by Toyota and Sony at the Tokyo motor show. The car is intended as a four-wheeled friend. It aims to provide affection, sympathy and encouragement. Like a dog welcoming its master, the car sits up, wags its tail and acknowledges its owner's presence using hydraulics(液压装置) and a multi-coloured LED display panel(引擎) across the front.

    While on the road, the car constantly monitors the driver's mood with pulse and sweat(汗) sensors on the joystick(操纵杆). Cameras focused on the eyes keep watch for any sigh of drowsiness. If a driver appears to be losing his or her cool, Pod will display warnings, play soft music and blow cold air at the face. Drivers are shaken awake with loud music and a shaking chair.

    To improve driving skills, Pod uses a comparison to score drivers, offer advice and rank all Pod owners. Toyota claims that the car will eventually be able to learn its owner's likes and dislikes by monitoring passenger conversations. If the car hears a favorite song being discussed, it will download the track from the Internet and play it without being asked. It will also recommend(推荐) restaurants that might suit the driver's taste and take photographs of passengers when they sound particularly happy.

    In keeping with the moodiness that is the car's main selling point, Pod expresses a form of road anger. If a driver brakes or swerves(急转弯) suddenly, the LED panel shows an angry red and the tail rises at the back.

    Anger is one of the car's ten “emotional states”. Another is sadness — a blue front with tear-shaped lights seemingly dropping from headlights — which appears after a flat tire or when gas is low.

    “We wanted to show that the cars can be cheerful and entertaining,” said Yasunori Sakamoto, part of the Toyota design team. Mr Sakamoto said Toyota has no plans to put Pod on the market. Sad, really.

    Exercise may help to safeguard the mind against depression(沮丧) through previously unknown effects on working muscles, according to a new study involving mice.

    Mental health experts have long been aware that even mild, repeated stress can contribute to the development of depression and other mood disorders in animals and people. Scientists have also known that exercise seems to cushion against depression. But precisely how exercise, a physical activity can reduce someone's risk for depression, a mood state, has been mysterious. So for the new study, researchers at the Karolinska Institute in Stockholm studied the brains and behavior of mice in a complicated and novel fashion.

    We can't ask mice if they are feeling cheerful or in low spirits. Instead, researchers have pictured certain behaviors that indicate depression in mice. If animals lose weight, stop seeking out a sugar solution when it's available — because, probably, they no longer experience normal pleasures — or give up trying to escape from the cold-water zone just freeze in place, they are categorized as depressed. And in the new experiment, after five weeks of frequent but low-level stress, such as being lightly shocked, mice displayed exactly those behaviors. They became depressed.

    The scientists could then have tested whether exercise blunts (延缓) the risk of developing depression after stress by having mice run first. But, frankly, from earlier research, they wanted to know how, so they bred pre-exercised mice. A wealth of earlier research by these scientists and others had shown that aerobic exercise, in both mice and people, increases the production within muscles of an enzyme (酶) called PGC-1alpha. The Karolinska scientists suspected（怀疑） that this enzyme somehow creates conditions within the body that protect the brain against depression. Then, the scientists exposed the animals, which without exercising, were in high levels of PGC-1alpha to five weeks of mild stress. The mice responded with slight symptoms of worry. But they did not develop depression. They continued to seek out sugar and fought to get out of the cold-water zone. Their high levels of PGC-1alpha appeared to make them depression-resistant（抵抗的）. Finally, to ensure that these findings are relevant to people, the researchers had a group of adult volunteers complete three weeks of frequent endurance training, consisting of 40 to 50 minutes of moderate cycling or jogging. The scientists conducted muscle biopsies (活体检查) before and after the program and found that by the end of the three weeks, the volunteers' muscle cells contained substantially more PGC-1alpha than at the study's start.

    The finding of these results, in the simplest terms, is that “you reduce the risk of getting depression when you exercise,” said Maria Lindskog, a researcher at the Karolinska Institute.

    Teens naturally ask parents for money for material things and entertainment. But as the need becomes more frequent, why not get a job so you can earn your own money? Working for your own money will give you a sense of accomplishment and the satisfaction of a job well done.

    Babysitting is a suitable job for teens. They are best suited as a mother's helper while the mother is working in another part of the house. Babysitting is not a job for girls alone. Boy babysitters are popular with families of boys. Parents rely on friends and neighbors' recommendations. Word of mouth is your best form of advertising.

    Pet-sitting involves caring for people's pets while the owners are on vacation or away for the day. A pet-sitter will be responsible for giving fresh food and water, walking dogs and cleaning out cat litter boxes. Although the pet-sitter does not spend the night, he is there often enough to bring in the mail, water plants and take the garbage out. Create a flyer with your name, prices and references, and pass it out to the families in your neighborhood.

    Yard work can be a seasonal job. Spring cleanup is needed for flower beds and preparing the yard for summer. Summer is the busiest time for yard work with lawn mowing (割草坪),edging and trimming(修剪) bushes. Fall is the time for sweeping leaves and planting seeds for spring. If you live in a northern climate, there may be snow that needs shoveling.

    Odd jobs can mean a variety of things, including painting, washing the pet, weeding the garden, cleaning out the basement, or helping to serve dinner at a party. Doing odd jobs may be a good match for someone with a busy schedule. Most odd jobs only take a few hours to complete.

    For Kim Duffy, sending away her teenage daughter was the best hope for saving the girl's life.

    Corinne, then 17, had been struggling with bulimia (贪食症) and anorexia (厌食症) for more than five years. Duffy and her husband, Terry, found a residential facility in Virginia, and Corinne signed on for a two-month stay in the summer of 2009.

    Today, Corinne's healthy and pursuing a master's degree in Colorado. She and her parents believe the holistic (整体) approach and individualized focus were key to her recovery. And they know they had access to unique resources. "We were fortunate," says Duffy. "We could pay for everything."

    But many can't. According to a report released in November 2014 by the Standing Committee on the Status of Women, between 600, 000 and one million Canadians suffer from an eating disorder. Public in patient programs often won't admit patients until they're in life-threatening condition. Private clinics often have a long waitlists and high costs-at Homewood, in Guelph, Ont., a room is $ 305 to $360 per day.

    The Duffs' struggle led then to connect other families with the quality of care they received in the United Sates. In late 2013, hey founded the WaterStone Clinic, a private eating disorder center in Toronto.

    Since the facility opened, 170 clients have received treatment. They take yoga, do art therapy and participate in meal preparation, building real-life skills with a support team. Programs run weekdays from 8 a. m. to 2 p. m., and notably, so far WaterStone has no waiting list.

    But this approach is costly: approximately $650 per day. Realizing that the price tag puts WaterStone out of reach for many, the Duffys created the WaterStone Foundation-a charity that provides aid to patients who can't afford treatment the following year. Candidates are assessed by two committees that make a decision based on clinical and financial need. Since 2014, the foundation has helped 100 people.

    Duffy also wants to change the public system. In June of this year, the foundation awarded ＄170, 000 to four Ontario hopitals offering creative treatment to eating disorder patients. "Yes, people need private treatment," she says, "but it's important to help out on a broader scale, too."

    More than 20 years ago, a skeleton called Little Foot turned up in a South African cave. The nearly complete skeleton was a member of the human family. Now researchers have freed most of the skeleton from its stony shell and analyzed the fossils (化石) and they say 3.67-million-years-old Little Foot belonged to a unique species.

    Researcher Ronald Clarke and his colleagues think Little Foot belonged to A. Prometheus (普罗米修斯南猿). Clarke works at the university of the Witwatersrand in Johannesburg South Africa. He studies fossilized humans and our relatives. Their foundings, published in four papers, have suggested the species A.Prometheus might have existed. Clarke has believed in that species for more than a decade, he found the first Little Foot's remains in a storage box of fossils in 1994. People began digging out the rest of the skeleton in 1997.

    Many other researchers instead argue that Little Foot likely belonged to a different species, which is known as A.africanus (南方古猿非洲种). Researcher Raymond Dart first identified A.africanus in 1924. He was studying the skull (头颅骨) of an ancient youngster called the Taung Child. Since then, people have turned up hundreds more A. africanus fossils in South African caves. Those include Sterkfontein, where Little Foot was found.

    The braincase is the part of the skull that holds the brain. And researchers found a partial braincase that Dart thought belonged to a different species in Makapansgat, one of those other caves. In 1948, Dart called this other species A. Prometheus, but he changed his mind after 1955. Instead, he said that braincase and another fossil at Makapansgat belonged to A.africanus. There was no A. Prometheus after all, he concluded.

    Clarke and his colleagues want to bring back the rejected species. They say Little Foot's distinctive skeleton, an adult female that is at least 90 percent complete, is solid evidence for it.
