The researchers created a long-termstudy in which they invited families in 16 school districts in central Pennsylvania to participate. In each family, a teenager, a younger sibling, their mother and their father were interviewed at home and then asked about their activities and self-worth five times over a period of seven years.

    The study authors were surprised to discover that when fathers spent more time alone with their teenagers, the kids reported they felt better about themselves. Something about the father's role in the family seemed to improve self-esteem among the teenagers in the study, said study author Susan McHale, a professor of human development at Pennsylvania State University.

  “Time spent with Dad often involves joking, teasing and other playful interactions. Fathers, as compared to mothers, were more involved in leisure activities and had more friend-like interactions with their children, which is crucial for youth social development,” the study showed.

    But Marta Flaum, a psychologist in Chappaqua , New York, said, “How these findings reflect the real world is areal question. The sample in the study is so small and so unrepresentative of more families in the country today that I'm not sure how much we cangeneralizing from it. In my community, in Westchester County, I don't see parents and teenagers spending much time together at all. Parents are often working so hard and have less time to be together with their kids.”

    However, Flaum encourages parents to make time for their kids no matter how much work they have to do. “Research like this reminds us of how important it is. The time we have with themis so short, ” she said.

    The first person in the world to receive two facial transplants says he is feeling well, three months after his latest groundbreaking operation.

    Jerame Hamon had his first transplanted face removed last year after signs of rejection following a treatment with an antibiotic (抗生素) during a cold.

    The 43 year old remained in a hospital in Paris without a face for two months while a compatible donor was sought.

    He said: “The first face I accepted immediately. This time it's the same.”

    Mr. Hamon suffers from neurofibromatosis (多发性神经纤维瘤), a genetic condition that spoiled his face severely.

    His first transplant, in 2010, was a success, but he caught a common cold in 2015 and was given antibiotics. The drug was incompatible with the immunosuppressive (免疫制疫的) treatment he was having to prevent a rejection of the transplanted material.

    The first signs of rejection came in 2016 and last November, the face, suffering from the death of most of cells, had to be removed.

    Mr. Hamon lived without a face in a room at Georges-Pompidou hospital in Paris without being able to see, speak or hear until January, when a face donor was found and the second transplant carried out.

    To avoid further rejection, Mr. Hamon—dubbed “the man with three faces” by French media ―had special treatment to clean the blood prior to the transplant.

    His new face remains smooth and motionless, and his skull, skin and features are yet to be fully matched. But he is positive about his recovery.

    “If I hadn't accepted this new face it would have been terrible. It's a question of identity… But here we are, it's good, it's me,” he told AFP news agency from the hospital, where he is still recovering.

    The hours-long operation was led by Prof Laurent Lantieri, a specialist in hand and face transplants who carried out Mr. Hamon's initial surgery eight years ago.

    “Today, we know that a double transplant is practicable, it's no longer in the field of research,” he told Le Parisien newspaper.

    Anaesthetist Bernard Cholley said: “Anyone who loses their face and then has to wait for a possible and imagined transplant for an unknown length of time—that's something that nobody has ever had to go through here.”

    “I'm amazed by the courage of a patient who has been able to get through such a different experience.”

    The first face transplant was carried out in 2005 in northern France. Since then, some 40 operations have been performed around the world.

    When asked about her childhood in the documentary Alive Inside, a 90-year-old woman with dementia(痴呆) replies, "I've forgotten so much." Filmmaker Michael Rossato-Bennett then plays music from her past for her. “That's Louis Armstrong,” she says. “He's singing When the Saints Go Marching In and it takes me back to my school days.” She then recalls exact details from her life.

Why does it happen? Music tends to accompany events that arouse emotions or otherwise make strong impressions on us — such as weddings and graduations. These kinds of experiences form strong memories, and the music and memories likely become intertwined(紧密相连) in our neural(神经的) networks, according to Julene Johnson, a professor at the University of California. Movements, such as dancing, also often pair with our experience of music, which can help form memories. Even many years later, hearing the music can bring back memories of these long-past events.

    As Alive Inside shows, music has this power even for many people with dementia. Researchers note that the brain areas that process and remember music are typically less damaged by dementia than other areas, and they think it may explain the phenomenon.

    They also pay attention to elderly people with dementia, especially those in nursing homes. "It's possible those long-term memories are still there," Johnson says, “but people just have a harder time accessing them because they're in a strange place and there are not a lot of circumstances in which someone could pull out those memories.”

    Johnson also notes that music is not universally useful for all people with dementia since there are some people with dementia whose brain area that recognizes music is damaged.

    Despite music's apparent benefits, few studies have explored its influence on memory recall in people with dementia. “It's really an untapped area,” Johnson says. Petr Janata is one researcher investigating the topic of music and memory. He says that scientists still do not have the answers for why and how music reawakens memories in people with dementia, but this phenomenon is real and it's just a matter of time before it's fully borne out by scientific research.

    Earthquakes strike suddenly at any time of the day or night, but there's no way to tell when. If an earthquake happens, it may cause many deaths, injuries and damage. So you need a good preparation ahead of time. Decide how and where your family will get together if separated. Choose an out­of­state friend or relative that the family members can call after the quake to report where they are and how they are. Know the safe places in each room: under the strong tables, desks, or against inside walls. Keep enough food, water and other things, including a flashlight, a radio, medicines and clothing.

    During the earthquake, you should keep a clear head and never be too nervous to know what to do. Protect your head and neck with your arms. If possible, take a book, a pillow or any other things to protect yourself from falling glass and ruins. If you are indoors, you must immediately lie under any strong furniture. If outdoors, move to an open area away from trees, buildings, walls or powerpoles. If you are in a narrow valley, move to the centre of it and look up for falling stones. If you are in a car, move to the side of the road and stop the car. Do not stop near buildings, power lines or on or under bridges. Stay in your car until the shaking stops.

    Do not move a badly injured person unless he is in great danger after the earthquake. Do not use the telephone immediately unless there is a serious injury or fire. Turn on your radio for instructions and news reports. Be prepared for aftershocks. If you want to leave your home, post a message inside your home telling your family members where you can be found.

My acquaintance, who never excelled in scholastic pursuits, possessed an innate acuity for aesthetic appreciation. On one occasion, I was engaged in the task of arranging a collection of floral blooms within a container, yet was unable to achieve a visually pleasing arrangement. She approached and, with a few deft motions of her hand, metamorphosed the ensemble into an arresting arrangement of blossoms. Upon receiving commendation for this remarkable proficiency, she dismissed the praise with a nonchalant gesture, perceiving her imaginative prowess as unremarkable.

Frequently, we tend to undervalue our innate competencies, perhaps because we are conditioned to regard only those attributes such as superior intellectual capacity, a proclivity for numerical computation, or an extensive lexicon as possessing intellectual merit. I was graced with the opportunity to discern a different perspective at an early stage of my life.

Upon my commencement of secondary education, a vocational advisor informed my parent that I was not suited for higher education due to my lackluster performance in a spelling component of a standardized assessment. Fortunately, my parent recognized the breadth of my intellectual endowments and advocated on my behalf, demanding that I be included in an academically rigorous curriculum. This episode fundamentally shaped the trajectory of my existence, illustrating the significance of not succumbing to the categorizations imposed by others and enabling me to reach my fullest intellectual capacity.

In the nascent years of the 1980s, Howard Gardner, an eminent scholar from Harvard, introduced the groundbreaking notion of "multiple intelligences." In his seminal work, "Frames of Mind: The Theory of Multiple Intelligences," he posited that intelligence transcends the conventional definition and encompasses a diverse spectrum of cognitive faculties.

What captivates me about the theory of multiple intelligences is its capacity to reconceptualize one's own capabilities and innate skills, particularly those that may not conform to the structured confines of academic paradigms. While it is acknowledged that a threshold of intellectual capability is necessary for success, the analytical competencies gauged by I.Q. assessments do not encompass the complete narrative. Hence, we ought to extol all of our talents and competencies, for they constitute the essence of what renders your individual cognitive capacity so extraordinary and distinctive.
