Scientists in the United States have developed a method that may help to predict earthquakes earlier. They say it could give people who live in deadly earthquake areas enough warning to leave before an earthquake occurs.
Currently, the most modern systems for predicting earthquakes find them only a short time before the event. Like most strong earthquakes, Wenchuan earthquake in 2008 and Haiti earthquake in 2010 were not identified early enough for people to flee the area, killing hundreds and thousands of people.
But scientists who study earthquakes are reporting that new technology could measure very small changes in the Earth’s surface.
Scientists performed experiments along California’s San Andreas Fault, an area famous for its earthquakes. Highly sensitive electrical devices are placed about one kilometer below ground in two different places. The devices were able to measure even small changes in air pressure on the Earth’s surface. The scientists say such changes are caused when rocks pushed together, forcing air out of small cracks in the rock.
Two earthquakes hit the area in late 2005. The first took place on Dec.25. A smaller earthquake struck five days later. The scientists noted changes in the earth’s surface about ten hours before the first quake struck. That quake measured three in intensity(强度). They then found similar changes taking place two hours before the other quake struck five days later.
If additional tests confirm the changes are linked to earthquakes, the scientists believe their equipment could be used for early warning systems. A system that provides a warning signal ten hours before a major earthquake could help move people from the area and save lives.
The scientists now hope they can find earthquakes with even greater intensity by placing their equipment deeper in the ground.

Throw out the bottles and boxes of drugs in your house．A new theory suggests that medicine could be bad for your health．This new theory argues that healing （the process of becoming healthy and strong again） is at our fingertips：we can be healthy by doing Reiki on a regular basis．

    Supporters of medical treatment argue that medicine should be trusted since it is effective and scientifically proven．They say that there is no need for spiritual methods such as Reiki, Yoga，Tai Chi．These waste our time，something that is quite precious in our material world．There is medicine that can kill our pain and x-rays that show us our broken bones．We must admit that these methods are very effective in the examples that they provide．However, there are some “everyday complaints”such as back pains，headaches，which are treated currently with medicine．When you have a headache，you take an Aspirin；when you cannot sleep，you take Xanax without thinking of the side effects of these．When you use these pills for a long period，you become dependent on them；you cannot sleep without them．We pay huge amounts of money but never get better．How about a safer and more economical way of healing?When doing Reiki to yourself，you do not need anything except your energy so it is very economical．Also，there are no side effects and it is scientifically explained．

    They also claim that serious illnesses such as HIV／AIDS and cancer cannot be treated without drugs．They think so because these patients spend the rest of their lives in the hospital taking medicine．How can Reiki make these people healthy again? It is very unfortunate that these patients have to live in the hospital losing their hair and weight because of the side effects of the medicine they take．Actually，instead of drugs which are expensive and have many side effects，you can use your energy to overcome the hardships of life，find an emotional balance，leave the stress of everyday life and let go of the everyday worries．

Some people may still hold that in our material world，everything depends on time．How

would it be possible to find time to do Reiki?In fact，Reiki does not require more than 15 minutes of our time．It is less time consuming than medicine if we think of all the time we spend taking medicine for some complaints and taking some more for the side effects as well．

Four out of ten women who diet end up heavier than when they started watching their waistline（腰围）, a study revealed today. The research also showed that a large percentage of women start noticing the pounds creeping back on just 21 days after reaching their ideal weight.

Yesterday, Dr Ian Campbell of the Jenny Craig weight management program said: 'In the UK 61.4 per cent of adults are overweight or obese. Successful weight management requires a long-term commitment in order to lose weight successfully and for good. Dieting can be a real challenge so setting realistic goals and remaining focused on them is important. Otherwise as this research shows, women could end up heavier than when they started.'

The 'Food: Body: Mind' report was publicized by Jenny Craig who quizzed 2000 women aged between 18 and 65 who diet regularly on their attitudes, beliefs and behaviors around weight loss. Six in ten said they are currently on a diet and one in five women said they are on a 'continuous diet'.

It found the most common triggers to start dieting was seeing their 'reflection in the mirror', preparing for a summer holiday or unflattering photos posted on social networking sites. Other popular reasons include comments by friends or relatives or their other half.

However, the study showed that one in ten give up within one day, while almost a fifth manage to make it to a week or more. The average is ten days. Many blamed pressure they put on themselves to lose weight too quickly for the weight gain, which leaves them with a bigger appetite than normal. Others blamed colleagues, who tuck into fatty lunches and snacks unaware of the effect it has on the dieter, while mothers who polish off their children's leftovers was another common cause of weight gain.
