Many Scientists and tech giants worldwide are trying to make thinner batteries for gadgets such as watches and mobile phones to reduce the weight of devices. On the other hand, some others are experimenting with whether we can abandon these of batteries altogether!

Researchers at the University of Colorado Boulder, for example, have developed a wearable technology that is powered by the human body. This means that future wearable devices might not have a battery. The battery is you.

The technology combines a stretchy material called polyimine, thermoelectric chips and liquid metal wires that can be worn either on your wrist or like a ring on your finger.

The findings, published in the journal science advances, mention that the technology uses thermoelectric generators converting the body’s internal temperature to electricity to provide power.

Researchers say the wearable can generate about one volt of energy for every square centimetre of skin space, which is less than most existing batteries but enough to power of wearable device.

“whenever you use a battery, you’re depleting that battery and will, eventually, need to replace it…the nice thing about our thermoelectric device is that you can wear it, and it provides you with constant power,” said Jianliang Xiao, senior author of the paper.

While Scientists have previously experimented with similar thermoelectric wearable devices are fully recyclable-making than a cleaner alternative to traditional electronics.


How did this strange looking galaxy from?

Astronomers turn detective’s when trying to figure out the cause of unusual Jumbles of stars, gas, dust like NGC 1316.

Inspection indicates that NGC 1316 enromus elliptical galaxy that show includes dark dust lanes usually found in a spiral galaxy. Detailed image taken by the Hubble space telescope shows details, however that help in reconstructing the history of this gigantic tangle.

Deep and wide images show huge collisional shells, while deep central images reveal fewer globular cluster of stars towards NGC 1316’s interior.

Such a effects are expected in galaxies that have undergone collisions or merging with are galaxies in the past few billion years.

The dark knots and Lanes of dust, predominant in the featured image indicate that one or more of the devoured galaxies were spiral galaxies. NGC 1316 spans about 50,000 light years and lies about 60 million light years away toward the constellation of the furnace (formax).
