Students invent gadgets to make life simpler, reduce energy consumption

You fold your transparent mobile phone so that it fits into your wallet and charge it on the way to office using your helmet. While in a meeting with your boss, you switch on your washing machine with your phone. Your fancy jacket runs your laptop as you make an award-winning presentation. If this sounds like a sci-fi movie script, you may soon be a part of it.

Flexible, single-layer mobile phones, solar jackets and helmets for energy generation and storage on-the-go and smart power out.

The transparent and foldable mobile phones are made of graphene, the new super material in the tech industry that’s extremely thin, strong and flexible.

The bulky solar panels of today could soon be replaced by aesthetic ‘solar trees’ near your offices and homes with ‘leaves’ made of small panels to generate electricity.

Fluid and flexible solar panels that can be moulded into any shape can make current solar panels a thing of the past as India targets generation of 100 GW.

Laughter may be best medicine for brain surgery

Neuroscientists at Emory University School of Medicine have discovered a focal pathway in the brain that when electrically stimulated causes immediate laughter, followed by a sense of calm and happiness, even during awake brain surgery. The effects of stimulation were observed in an epilepsy patient undergoing diagnostic monitoring for seizure diagnosis. These effects were then harnessed to help her complete a separate awake brain surgery two days later.

The behavioral effects of direct electrical stimulation of the cingulum bundle, a white matter tract in the brain, were confirmed in two other epilepsy patients undergoing diagnostic monitoring. The findings are scheduled for publication in the Journal of Clinical Investigation. Videos of the effects of cingulum bundle stimulation are available, with the patient’s identity obscured.

A space rock collision may explain how this exoplanet was born

Cataclysmic collisions between space rocks have helped explain some of the solar system’s biggest mysteries, from how the moon formed to how Uranus got its lopsided rotation. But convincing evidence for such events happening outside of the solar system is scant.

Now scientists think that they have found the first known example of a near head-on collision between two massive worlds in another planetary system, roughly 2,000 light-years away from Earth.

The chance discovery came while researchers were observing Kepler 107, a sunlike star with four orbiting planets first described in 2014, to determine each planet’s mass. Surprisingly, the star’s two innermost planets, each roughly 1.5 times the size of Earth, have dramatically different masses, the team reports February 4 in Nature Astronomy. Analysis of each planet’s mass and size revealed that Kepler 107c is roughly twice as dense as Kepler 107b. That finding suggests that Kepler 107c has a large iron-rich core, similar to the solar system’s innermost planet, Mercury, the scientists say.

How to make your own intelligent speaker with the help of a cell phone that you no longer use

In the last two years a great variety of intelligent speakers emerged, that is: speakers that integrate a virtual assistant such as Siri, Alexa or the Google Assistant (Google Assistant).

Now, these assistants are different devices, among them, for example, there is the Google Assistant that is in the phones that have Android Marshmallow (6.0) and onwards.

With this in mind, it is possible to convert a traditional speaker into a smart speaker. You only need to have a mobile with the Google Assistant and follow the following steps:

To know if the mobile integrates the Wizard, simply hold the Home button pressed for a few seconds and say “Ok, Google” to summon it.

In order for the assistant to be attentive to the user’s voice commands, you have to enter the cell configuration menu (by clicking on the nut icon) then go to Google / Search, the assistant and there activate the Voice Match option.
