Enjoy creative inventions

Every November, Time magazine picks out “The 25 Best Inventions” of the year. These are the things that have made our lives different. TEENS has chosen three of the most interesting ones on the list. If you want to know more, please click Here.

Ember Mug

It’s hard to always keep coffee at the right temperature, especially in winter. It’s too hat to drink at first, but before we know it, it gets too cold and loses all its taste. According to Time, the perfect level of warmth for a cup of coffee only lasts for 37 seconds, which makes the Ember Mug a great invention. It keeps your coffee or tea at a certain temperature, anywhere between 48 and 62, once you set it through a smartphone app.

Tasty One Top

TV cooking shows make it look so easy, but it’s almost impossible to get the recipes to look the same as how the professionals make them. However, the Tasty One Top DIY cooking helps. Developed by Buzzfeed, the cooker can be connected to a smartphone app, which has more than 1,700 recipes and videos. You choose a recipe and the app will let the cooker know what to do. For example, it’ll tell you when to turn your steak or when to add certain ingredients.

Jibo

Smart speakers from companies like Amazon and Xiaomi have added a lot of fun to our lives. Though they’re still faceless speakers. However, Jibo, developed by MIT professor Cynthia Breazeal, has brought smart technology to life. Said to be “the world’s first social robot for the home”, Jibo looks like a cartoon character, a round head and a voice that sounds like a 10-year-old boy. Inside its “head”, there are different sensors and cameras, which allow it to recognize (辨认) faces and speech. Jibo will move to face you whenever you talk to it. It can also set alarms, remind you of important things, tell you the weather and read news or messages from your friends and family.

【题目】

Solar storms shake Earth’s magnetic field(磁场). They not only influence human technology, but also animals, reported Forbes.

Studies show that many animals use changes in Earth’s magnetic field to find directions. These changes provide the animals a general compass(指南针) for south and north. Animals can also use them as landmarks.

For example, scientists have found special cells in part of a bird’s eye nervous system(神经系统). They seem to react to changes in the magnetic field.

Some fish species, like the common trouthave cells with magnetic sensors in their nasal cavity(鼻腔). In 1994 “magnetic sense” was also discovered in sea turtles.

Some whale species may use magnetic sense to navigate (导航) the oceans. A dysfunction of this sense may explain the still mysterious beachings (动物搁浅). Sometimes several hundred animals, such as whales and dolphins, are driven out of water along beaches. They usually can’t breathe under their own weight and die slowly.
