Stephen Hawking was the first to propose that not everything that comes in contact with a black hole succumbs to its immense gravity and inevitable nothingness. In fact, tiny particles of light, known as photons, are sometimes ejected back out of the black hole, robbing it of energy. This gradual loss of mass over time means that every black hole eventually evaporates out of existence.
Researchers in the US have created a battery capable of being recharged hundreds of thousands of times without showing signs of wear, spelling a potential end to electronics rendered useless by dead cells.

The batteries of today are mainly lithium, and over time that lithium corrodes inside the battery. Instead of lithium, researchers at UC Irvine have used gold nanowires to store electricity, and h
Aerojet Rocketdyne’s operation in Redmond, Wash., has won a $67 million contract from NASA to design and develop an advanced electric propulsion system that could power future trips to an asteroid and Mars.
The goal of the 36-month project is to deliver an integrated system that could improve fuel efficiency by a factor of 10 over today’s chemical rocket propulsion systems, and double t
A world crew of researchers has found a 1,000-km (600-mile) lengthy coral reef sitting on the murky, muddy mouth of the Amazon river, in line with new studies.
No matter how well we think we know our planet, there are always surprises – and a big one at that. The Amazon is the Earth’s crown river. The largest by water discharge, the second by length, its basin covers approximately 7,050,000 square kilometres (2,720,
Today's massive amounts of digital data have caused researchers worldwide to develop data storage technologies, such as DNA-based storage, that are meant to be capable of keeping data for the longest possible time.

Now, a new mini disc developed by researchers in the United Kingdom is said to be able to store up to 300 terabytes worth of information for billions of years without suffering any deterioration of
DNA is present in every cell of our body that means it is present in almost 100 trillion cells and the total DNA person in these cells can stretch from the Earth to the Sun hundreds of times. DNA is undoubtedly a long structure, but if you compare its width with your hair then it…
In physics, gravitational waves are ripples in the spacetime curvature which propagate as waves, travelling outward from the source. Predicted in 1916 by Albert Einstein on the basis of his theory of general relativity, gravitational waves transport energy as gravitational radiation.
