Sixteen dollars!That's the price of a movie ticket plus tax in Los Angeles. Thanks to an Indian chemist,that amount of cash could also provide clean water for a year for a poor family in the developing world.

Thalappil Pradeep,a chemistry professor at the Indian Institute of Technology,spent 14 years developing a water filter(滤水器) system that can. remove pollutants from India's groundwater as it is being pumped. The water purifier,which Pradeep first showed to the public in 2012,is the first filter of its kind in India. The country's federal government recently decided to place the pumps across the nation,Pradeep said. He and a team of students formed a company to keep up with the work,he added.

The device（设备） come in two sizes and at three price levels,which include installation (安装) costs: The $16 version is for homes; a larger one that can be used at schools and office buildings is $500 (connecting a whole village costs $700 more) . The larger purifier,which stands nine feet tall,produces about 80 gallons of clean water per hour.

The daily hard work in the office can be extremely exhausting. Staring at a computer screen for eight hours a day seems like modem business practice. It's also a common belief that you 5 re more likely to complete your "tasks if you keep your bottom planted in your chair all day. But that opinion is erroneous. In fact,taking breaks regularly throughout your workday can increase your productivity and creativity as it helps to keep the mental iuices flowing. ,

A new study in the journal Cognition overturns an old theory about the nature of attention and shows that brief breaks from a task can greatly improve one's ability to focus on that task for a longer period of time. The study gets to the most important part of what so many of us experience when doing the same task for a long period of time; after a while you begin to lose your focus and your ability to perform the task well. "Basically,if you don 51 take small breaks during the day,you re likely to suffer from exhaustion and won 51 complete your task to the highest level of your ability,” says Alejandro Lleras,the leader of the study.

In addition,new research shows that your brain can be trained and developed iike a muscle. Mental concentration is part of that training. Just as your muscles become tired after a workout,so does your brain. It needs a rest to recover and move on.

So,what can you do if you feel guilty about taking a break during the workday? Remember that taking breaks is a good,necessary thing. We* re trying to prove ourselves and our worth to the company,which makes us think that taking breaks prevents us from achieving our goals,but in fact it's not. It's necessary to do your best work.

Nearly every driver has experienced that feeling of great tiredness,where it becomes almost impossible to stay awake at the wheel. 14-year-old Katherine Wu is too young to have experienced this situation firsthand. However slie noticed how difficult it was for her dad to remain awake while driving back from ?ieir femiiy vacations in Florida to their home in Maryland. Her mom had to talk to her dad all the way.

Her inversion ,“Driver's Companion”，can notice driver sleepiness and warn the driver if he or she is too t?ed to be on the road.

The user wears a headset(耳机) ，which sends information about the driver' s brain waves (月凶电波) to a tiny computer. The computer can be placed in front of the driver. The 吵对撕(系统) then gives warnings,if needed. As the driver becomes sleepier,red color will be shown to warn him or her. The driver will also hear messages warning him to get off the road. The machine can say, “You’ re tired. Please take a break."

After sending her invention to the 2014 Discovery Education 3M Young Scientist Challenge,Wu was chosen as a finalist and was able to work with Dr. Jesse Miller,who is a product development specialist.

“He helped me understand how important it IS to make sure that my invention wprked for the people who were using it and that it was user-friendly,” Wu says.

As a young scientist,Wu has some advice for other students of her age: ul would like to tell them that they should choose something they* re interested in.
