The virus “Ebola” is named after the Ebola River in what is now the Democratic Republic of the Congo. That’s where the virus was discovered in 1976. A person can only get Ebola through direct contact with an infected person’s bodily fluids, for example, sweat or spit. Additionally, the virus can get into your body through your eyes and mouth if those areas come into contact with something that contains the bodily fluids of an infected person. That’s why health care workers are supposed to keep themselves completely covered while treating patients.
The deadliest Ebola outbreak is spreading fast in Western Africa, taking over 900 lives so far. The health systems in Guinea, Sierra Leone and Liberia are severely lacking in resources, and health care workers may not have access to adequate protective clothing when working in rural clinics, where the proper protections are lacking. Since Guinea, Sierra Leone and Liberia share a border; it’s easier for people to move from one country to another, increasing the risk for disease spread.
For now, all doctors can do is treat the symptoms and provide supportive care like monitoring heart rate, blood pressure, and breathing while making sure the patients’ fluids are supplied. Sometimes patients are given antibiotics(抗生素) to treat other possible infections. The hope is to make the patient pull through the infection so their immune system can eventually clear the virus. The people who survive Ebola have created enough antibodies to kill it.
There are several promising drugs and vaccines in development, but since Ebola is less common—and research about it is not well funded — there is no drug or vaccine that has been approved for use in humans. Many of the other drugs and vaccines have not yet been tested in humans. The WHO (World Health Organization) is meeting next week to discuss whether experimental treatments should be used during this outbreak.

Most parents of kids under age 8 don't worry about how much time they spend watching TV or using other media, from computers to smart phones to tablets PCs, according to a new survey that found a child's use of media often reflects how much time parents spend in the similar way.
¨We generally found that media use is not a source of conflict in the home" for families with young children, Ellen Wartella, a researcher from Northwestem University, told USA Today. She led a survey of 2,326 parents who have children 8 and younger.It found that in 80 percent of families, children's media use was not a problem, with 55 percent “not too" or“ not at all" concerned about it. It also showed parents have more positive than negative feelings about how media consumption affects a child's learning and the development of creativity.The exception is video games, which are viewed more negatively than TV, computers or mobile devices.“Parents rated video games as more likely to have a negative effect on children's school performance, attention time, creativity, social skills, behavior and sleep than any other medium," the researchers said in a news conference about the survey.
¨The findings exposes a generational shift (轉(zhuǎn)移) in parental attitudes about technology's role in young children's lives," said Wartella.“Today's parents grew up with technology as a central pact of their lives, so they think about it differently than earlier generations of parents, instead of a battle with kids on one side and parents on the other, the use of media and technology has become a family affair. "
The researchers identified three media environments created by parents: media-centric (39 percent of families) , media-moderate (45%)and media-light (16%). Children in media-centric families spend at least three hours more each day watching TV or using computers, video games and tablet PCs don't make parenting easier.And 88 percent of parents say they are most likely to turn to toys or activities to keep their children occupied.Slightly fewer turn to books (79%) and TV(78%).
The survey didn't look at how media affects children. That's a topic that the American Academy of Pediatrics has handled a number of times. The AAP says studies have found too much media use can lead to attention- problems, school difficulties, sleep and eating disorders and being fat. In addition, the Internet and cell phones can provide platforms for illegal and risky behaviors.¨By limiting screen time and offering educational media and non-electronic formats (格式)such as books, newspapers and board games, and watching television with their children, parents can help guide their children's media experience. Putting questionable content into context and teaching kids a700ut advertising contributes to their media literacy (素養(yǎng)) ," it says.
The pediatricians' group says parents should have “screen-free zones" and TV should be turned off during dinner. At most, it recommends children and teens engage with entertainment media for no more than two hours a day and that should be high-quality content. It is important for kids to spend time on outdoor play, reading, hobbies and using their imaginations in free play.“ Kids under 2 should not use television and other entertainment media because their brains are developing quickly and they learn best from direct human interaction," the group says.
An article on screen time by t.he Mayo Clinic also notes problems linked t.o over screen time, including being fat, irregular sleep , behavioral problems , weak school performance , violence and less time for active and creative play.

Until just a few years ago,we doctors believed that the brain stopped making new neural(神經(jīng)系統(tǒng)的)connections (meaning that your memory began to get worse)when the body stopped developing,usually in your early 20s. And we knew that,like any other body part,neurons weaken as we age. Loss of brain function due to neural breakdown was assumed to be a normal,unavoidable part of aging.
It turns out that we were wrong. In the past few years,it has been discovered that you can,in fact,make new neurons starting in your 20s and continuing well into old age. You can literally rewire the brain with new parts as the older parts wear out. How?Simple:Keep learning. Just as your body can pack on and condition new muscle,your brain can rebuild used-up neurons.
How strong is the evidence for this?Strong enough that a $200 million industry devoted to brain boosting software (products like Brain Age,MindFit,and Lumosity that supposedly improve your memory function)has sprung up out of nowhere. All“mental fitness”means are keeping your memory intact(everything from phone numbers to how to throw a football).So what can you do to stay smart?
Keep blood pressure down. People with high blood pressure are more likely to develop cognitive impairment later in life.
Eat more vitamins. Like E(in nuts and sunflower seeds),B6 and B12(beef,tuna),and folic acid(leafy greens,citrus,berries),which help keep your brain’s chemistry in balance.
Exercise your brain. This is the best way to rebuild and strengthen those precious neurons. Learn to play chess or the guitar. When you’re at a stoplight,try to recall the starting lineup of the 1983 Celtics. See a movie that doesn’t feature Ben Stiller. Or read,like,a book.
Title:How to keep the 1.________smart?
Previous 2.____ | The brain no longer makes new neural connections once the 3.________ of one’s body has stopped. |
New 4. ________ | ●New neurons continue to occur even in one’s old age. ●5.________contributes to the development of the new parts of your brain. ●Many products which claim to improve your brain function appear in 6.the _________. |
7. _______ | ●Keep yourself away from 8._________blood pressure. ●9._________in more vitamins for the needs of your brain. ●10._______your brain as much as you can. |
