5D Disc Developed that can store Data for Billion of Years

Researchers from University of Southampton have developed a new mini disc that can store up to 360 terabytes of information for billions of years. The new data storage technology is in the form of a tiny five-dimensional disc which not only has a huge capacity but can save information for as long as 14 billion years.

The disc is made of nonstructured glass and can withstand extreme temperatures up to 190 degrees Celsius. It will possibly prove a better way to store massive amounts of digital data without deterioration.  

Mystery of Missing Asteroid Solved

For many years, scientists believed that asteroids and comets fell into the Sun’s atmosphere and end their life. When a team of international researchers created an advanced model of near-Earth objects population, they observed that there are less numbers of NEOs than what has been estimated. Researchers verified their calculations and reached the conclusion that the problem was not in their analysis but in their understanding of asteroids demise.

Researchers found that asteroids are destroyed by the Sun long before making an actual collision. Sun can destroy asteroid at a distance much farther than initially thought.

Neanderthals and Modern Humans Interbred Much Earlier than Previously Thought

Neanderthals are extinct, giant cousins of modern humans. By sequencing DNA of these extinct species, researchers have found that Neanderthals and modern humans interbred much earlier than previously thought. Initially, it was thought that crossbreeding event took place about 60,000 years ago.

The finding also provides new insight into migration patterns of humans and suggests that a small population of ancestors of modern humans mixed up with other members of human family before migration ‘out of Africa.’ The sexual contact occurred between Neanderthals and only those modern humans who left the continent of Africa.

Scientists Create 3D Printed Organs and Tissues 

Scientists from Wake Forest Baptist Medical Center have created 3D printed organs and tissues for the first time and these organs have a potential to replace the damaged ones. The most remarkable thing about 3D printer is that it is actually capable of making living tissues. Once these organs are attached to the bodies, they can develop blood vessels and start function normally. Currently, these organs are implanted in mice and rats but scientists are striving hard to improve the technology and hoping to place them in actual patients soon.

New Digital Map of Martian Surface

British mapping agency Ordnance Survey has created an easy-to-read digital map of Mars. Using NASA data, company has developed a map that shows Martian’s terrain and features in detail and makes this alien world look like just another place for hiking.

The new map shows a region on Mars known as Arabia Terra and covers about 3.8 million square miles, about 7 percent of Mars’ surface. Since space agencies are aiming to send humans on Mars in future, the map can help understand alien surface better and make realistic policies.
