After years of research and testing, the hybrid car was developed and put on the market. It' s an interesting and exciting new improvement in today' s world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources.

    The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car' s engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.

    A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144-volt battery pack is actually recharged through the energy that is produced when the car's brakes are used. This is referred to as “regenerative braking”, because it generates electricity.

    Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.

    Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, “I am low on gas”. When it completely runs out, the warning reads, “YOU ARE NOW OUT OF GAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

    Climate change has had a number of effects on cities around the world, including rising see levels. And, this has become an especially big problem for coastal cities. City officials must now prepare for higher tides on their coasts. The American city of Miami is one example. Located in South Florida, Miami is home to nearly 3 million people and billions of dollars in land and buildings.

    Miami is one of the cities in America most at risk for rising sea levels. The waterfront is central to Miami's culture and economy. But as the seas rise with climate change .the water will not stay put. Large parts of South Florida are in danger of being under water in the coming years. Across Biscayne Bay, the City of Miami Beach is making improvements - raising streets, adding water pumps and more.

    It is costing the city a lot of money. Local communities will spend 500 million dollars for the improvements. Thankfully, the residents, the folks that are paying the bill for this work, realize that the cost of doing nothing is much greater. A possibility officials are discussing with residents is for city to buy homes in some places where flooding has been a problem. The city would then turn that land into parks of grassland that could hold the water.

    Over time, the city may need to take bigger risks. Miami's future depends largely on how much, and how fast, the oceans rise.

    Caroline Lewis leads the climate activism group, the CLEO Institute. She says cities cannot avoid the need to move inland. But, she says，a well-planned withdrawal (撤退) could include measures to keep people safely in place for as long as possible. And, she says, the world could learn from such a model. In these two Florida cities built on wetlands, there remains a lot of hopefulness.

    Many people tend to complain about not having good friends in their lives. Sadly, they seem to think that their own company is not enough to make them happy. Nothing could be further from the truth though. In order to get along with others, the first thing you need to do is learn to get along with yourself. Only in this way will you succeed in developing healthy, solid relationships with others.

    Listen to your inner voice. Remember that inner voice that keeps whispering to you what you really want and need as well as what you do not really want and need. It is about time you started listening to it. In order to get to know yourself in depth, it is important to learn and accept what you want and what you do not want.

    Learn to enjoy your own company. You will be surprised to find out how many things you can do by yourself and actually have fun in the process. Reading romantic novels, poetry or science fiction is only a few of the things that you can do by yourself, which not only can offer you hours of enjoyment, but also the chance to get to know yourself better.

    Satisfy yourself. Pay special attention to your personal hygiene(卫生). Do your hair and nails often and experiment with new styles. Follow a healthy diet and exercise regularly to stay in good shape. No matter how busy your daily schedule is, always find at least an hour per day for yourself, when you can either relax doing absolutely nothing, or doing something that you enjoy most.

    Learn to respect your own boundaries. Find out what your boundaries are and learn to respect them. You are the only one who knows what you can accept and what you cannot.

    New research brings some good news for lovers of spicy(辛辣的) foods, after finding that eating hot red chili peppers might help to extend lifespan（寿命）.

    Consuming hot red chili peppers might reduce death risk, say Chopan and Littenberg from the research team. In hot peppers, such as Mexico peppers, the strong flavor comes from a compound(复合物), which does not exist in sweet peppers or onions. Studies have suggested that this compound can offer a welth of health benefits.

    A study of more than 16,000 people in the United States revealed that individuals who consumed red chili peppers had a lower risk of death from all causes over an average of 18 years than those who did not eat the spicy food. Compared with participants who did not consume hot red chili peppers, those who did were found to be at 13 percent reduced risk of all-cause death.

    For example, a recent study reported by Medical News Today, found that the compound might have the potential to stop breast cancer, while an earlier study linked the compound to a reduced risk of digest system cancers. Still, the available data suggested that hot red chili pepper consumption was most strongly associated with a reduced risk of death from heart disease.

    While the researchers are unable to identify the concrete compound by which red chili peppers might extend lifepan, the team says that it is likely due to the compound that is effectively against obesity(肥胖症).

    Overall, the team says that these latest findings support those of the 2015 study, linking spicy food intake to reduced risk of death by showing “a significant decrease in death associated with hot red chili pepper consumption.” However, Chopan and Littenberg note that the earlier study was only conducted in Chinese adults, so the now research makes these findings more credible.

    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates(灵长类)to be cloned. Another one named Tetra was produced in the late 1990s by embryo(胚胎)splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(卵原子核)with DNA from a differentiated body cell. This Dolly method, known as somatic(躯体的) cell nuclear transfer(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA.

    Success came from adopting several new techniques. These included a new type of microscopy(显微术) to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, and it would be far too inefficient, far too unsafe, and it is also pointless.

    But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough as a novel model system for scientists studying human biology and disease.
