Have you ever wanted to make a phone call but you couldn't? Perhaps because there is no signal.Or because you've left your mobile at home.Or because your battery has gone dead.It's frustrating, right? So far no one has found a solution to the problem of not receiving a signal, but now BIpho Phones have just brought out their latest invention—a mobile phone that is always with you and never runs out of energy.

The Permaphone is a telephone implant(植入物).The receiver sits behind your ear, the microphone is in the tip of your nose and the flexible touch screen is under a layer of completely transparent(透明的) artificial skin on the inside of your wrist.All you need is a quick visit to a hospital for a simple operation and then you are your mobile—a walking talking telephone.It gets its power from your body.Every time you move, you produce kinetic(运动的） energy.The Permaphone captures this energy and so never goes dead.

The operation took only five minutes and was completely painless and since I left the hospital I've been experimenting with my new phone implant.After a day or two it feels perfectly natural: just like a part of my body.It's so simple to switch the phone on and off, to turn the volume(音量) up or down and to access all the functions.

So are phone implants the future of mobile phone technology? Well, maybe.However, there are some drawbacks too.For example, when you have a cold it may not be very convenient to have the microphone in your nose.And although Blpho say it is completely waterproof, I wonder how confident you would feel when you go swimming with your Permaphone.And finally, one more question that they haven't answered yet: do you need to go back to hospital for another operation every time you want to update your phone?

Giving Mary Poppins’s magic umbrella some serious competition is the all new high-tech “Oombrella”---not only can it predict the weather, it’s also impossible to lose. The smart umbrella syncs(同步进行) with a smartphone app, sending users updates about weather conditions 30 minutes in advance, and reminders if they happen to leave the device behind. And here’s the added bonus – it won’t ever flip inside-out.

Designed by French company Wezzoo, the rainbow-colored umbrella comes in two versions – classic and modern. The classic is 3.1-ft long with a curved handle, while the modern version is 0.8-ft long with a straight handle. The company describes the device as a ‘portable weather station’, made of a reflective surface with built in sensors that record real-time data such as light, humidity, pressure, and temperature. The umbrella collects and processes this data as well as information from a social media community before sending out alerts about when it’s going to start raining.

And if the user happens to accidentally forget it at home on a potentially rainy day, or leaves it in a restaurant, similar alerts will be sent out using GPS technology to make sure you don’t lose it.

“We wanted to make this umbrella unforgettable in terms of design, too,” explains Alexandre, of Escabo design studio. “We developed an exclusive material. It makes you feel you are holding an aurora borealis(北极光) in your hands. It has effects that are amazing with the light and always changing. It really makes the umbrella special.” The ‘capsule’ that integrates all the technology, making the umbrella smart, is located in the handle.

The umbrella is all set to hit global online and physical stores this fall. According to a company spokesperson, it will retail at 79 euros ($86), but the early bird price on Kickstarter is 59 euros ($64). For those who are rather attached to their current umbrellas, the company will also release an ‘Oombrella capsule’ that can transform any umbrella into a smart device. Now, if only it could make us fly like Mary Poppins!

A Teenage Inventor

The world could be one step closer to quick an inexpensive Ebola detection （埃博拉检测）thanks to a teenager from Connecticut （康涅狄格州）. b

Olivia Hallisey, a junior at Greenwich High School, was awarded $50，000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death.Olivia’s method is to ask patients to put their saliva （唾液）onto a testing card. The card changes color if the person is catching Ebloa, Present Ebola tests take up to 12 hours and cost $1,000.Olivia’s method, however, can be done just in 30 minutes for about $25.Besides, the sample （样本)doesn’t have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.

Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa, worried about the fact that, while the acts of involvement can improve present detection methods are costly,time-consuming and require complex tools.Olivia got help from her science research teacher.She drew out directions from past research,and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.

“What affects one country affects everyone,”Olivia told CNBC. “We have to work together to find answers to the huge challenges which cause harm to the global health.” The Connecticut’s teen,who hopes to become a doctor one day, was named Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.

Olivia hopes her success will inspire other girls interested in science and computers. “I would just encourage girls to try it in the beginning, and remind them that they don t have to feel naturally drawn or feel like they have a special talent for maths or science,” she told CNBC, but just really look at something they are and then think how to improve something or make it more enjoyable or relate it to their interests.”
