Scientists have developed a way of charging mobile phones using urine

Yes; Soon Mobile phone owners could be able to charge their batteries with their own urine.
Scientists working at the Bristol Robotics Laboratory have described the “breakthrough” finding of charging cell phones using urine as the power source to generate electricity.

Dr Ioannis Ieropoulos, an expert at harnessing power from unusual sources using microbial fuel cells at the University of West England, Bristol, which was also involved in the research, said the urine-powered phone is a ‘world first’.
‘No-one has harnessed power from urine so it’s an exciting discovery.

A fuel cell which can use the energy from your URINE to power a mobile phone could mean a future of cheap energy.
The miniature invention which costs just £2 has the capability to generate electricity - meaning a single visit to the toilet has been used to recharge a smartphone for the first time.
Scientists have been able to provide three hours of phone calls for every six hours of charge time - all from 600ml of urine.
The microbial fuel cell technology provides enormous potential to enable people to stay connected in areas that are off grid using "pee power".

The world first has been developed at the University of the West of England in Bristol by Professor Ioannis Ieropoulos and his team.
Professor Ieropoulos said: "We are excited to announce several global firsts - this development was possible by employing a new design of microbial fuel cells that allowed scaling up without power density losses.

 

 Several energy-harvesting systems have been tested and results have demonstrated that the charging circuitry of commercially available phones may consume up to 38% of energy on top of the battery capacity.

One Million Earths Can Fit Inside The Sun

Ancient astronomers once believed the Earth was at the centre of the Universe but now we know that the Sun is at the centre of our Solar System and our planets orbit the Sun. The Sun makes up 99.8% of the entire mass of the whole Solar System. One million Earths would be needed to be the same size as the Sun.

The visible part of the sun is about 10,000 degrees Fahrenheit (5,500 degrees Celsius), while temperatures in the core reach more than 27 million F (15 million C), driven by nuclear reactions. One would need to explode 100 billion tons of dynamite every second to match the energy produced by the sun, according to NASA.
The sun is one of more than 100 billion stars in the Milky Way. It orbits some 25,000 light-years from the galactic core, completing a revolution once every 250 million years or so. The sun is relatively young, part of a generation of stars known as Population I, which are relatively rich in elements heavier than helium. An older generation of stars is called Population II, and an earlier generation of Population III may have existed, although no members of this generation are known yet.

Scientists Release Audio Of Gargantuan Black Hole Collision

Approximately 1.4 billion years ago, two gargantuan black holes — one 14 times as large as the Sun, the other eight times as large — collided. This caused them to merge, creating an even larger black hole 21 times as large as the Sun that then released a wave of gravitational energy as massive as one Sun.
Now, all these millennia later, that enormous amount of energy, in the form of gravitational waves, finally arrived at Earth and tripped the LIGO( Laser Interferometer Gravitational ) detectors.

That said, what you’re hearing above is the scientists’ audio representation of the event, not an actual “field recording.” When LIGO’s detectors capture gravitational waves, they’re not collecting audio data, but data about ripples in space-time that can be represented by audio perceptible to the human ear.
And that audio probably doesn’t sound like you’d think it would. The adjusted sound is something of a dull bloop, and the pitch-adjusted sound is more like a smooth whistle.
In addition to those sounds of the gravitational waves from the newly announced black hole collision (first detected last December), you’ll hear the audio of LIGO’s historic first detection of gravitational waves back in September.

That first detection marked a monumental moment in science, proving the very existence of gravitational waves — ripples in space time caused by extraordinary events — and confirming Albert Einstein’s theories about general relativity made over 100 years ago.
Now, with this second detection of gravitational waves under their belts, LIGO scientists plan to continue searching for gravitational waves and, in the words of LIGO deputy director Albert Lazzarini, unlock the secrets of “the darkest yet most energetic events in our universe.”
