Scientists are able to shrink objects

For the first time, researchers have produced nano-objects by shrinking. First, they assembled 3D objects in a special hydrogel, then an acid caused the gel and its contents to shrink. The 3D design thus became an object ten to a thousand times smaller - without distortions or defects. The big advantage: this "implosion fabrication" method is feasible with conventional technology and enables completely new nanoconstructs, as the researchers report in the specialist journal "Science".

Team invents a method to shrink objects to the nanoscale
Researchers at the Massachusetts Institute of Technology (MIT) have developed a method that, for the first time, produces detailed 3D objects on a nanoscale - by shrinking. To do this, they first position the components of the object in a larger pre-variant. Then they shrink the whole thing and create the desired object in nano format.

This so-called "implosion fabrication" is made possible by a special hydrogel made of polyacrylate/polyacrylamide. If, for example, this gel is exposed to an acid, the water content and the chemical bonds change so that the entire gel contracts evenly.

The new method considerably expands the existing possibilities of nano-fabrication, as the researchers emphasize:

"With implosion fabrication, we can produce all kinds of structures, gradients, unconnected shapes or objects from several materials"

The big advantage is that these 3D structures can be assembled and designed before shrinking with a precision that is hardly possible in nano size.

Stephen Hawking's Final Book gives brief Answers to Big Questions

Stephen Hawking's final work was launched by his children on Monday which discuss issues from Existence of God to Time Travel and other big questions. His children completed his final book after he died last year.

Stephen started his book last year to answer the common question which he encountered many times from public. The title of the book is ''Brief Answers to Big Questions''.

His daughter, Lucy Hawking, said he was regularly asked for such question and this book contains his clear and most authentic answers. We all wish he was here to see it published, she added.

What are these big questions and what did he write answers to them?

Is there a God?How Did it All Began?What is inside a black hole?Can we predict the future?Is Time Travel possible?Will we survive on Earth?Is there any other intelligent life in Universe?Should we colonize space?How do we shape the future?Multiple challenges Stephen Hawking says the simplest explanation is that God does not exist and…

Human flights to ISS will begin in 2019

NASA has confirmed that manned space flight will be carried by SpaceX and Boeing in the mid of 2019.SpaceX rocket for ISS will depart in June 2019 while Boeing spacecraft will go in August 2019.
It will be the first US mission since the retirement of the shuttle in 2011.NASA's astronauts are currently using Russian made Soyuz spacecraft and its contract will end in June 2019.NASA said on 4th of the October that it will give monthly updates 

Phil McAlister who is the director of commercial flights in NASA said in Blog that 

New Updates schedule is better but launch schedule may be uncertainHe also said these are new spacecraft and lot of engineering work has to be done before take off.

Back in 2014 both the SpaceX and Boeing received $6.8bn from NASA to build spacecraft that will take humans to ISS.

Boeing has said they will be ready for Orbital Flight Test in March 2019.
The Success of this manned space shuttle will be a great achievement of the commercial space industry, and NASA will …

The Mystery of ISS leak

A leak was found on Russian made Soyuz MS-09 Spacecraft on International Space Station by Astronauts which caused loss of oxygen on 30 Aug. First, it was thought it was due to a Meteorite hit to ISS but Russia rejected saying this leak was man-made.

Recently NASA's head Jim Bridenstine said that investigations will be done soon to determine the cause of leak to ISS which caused a brief deficiency of Oxygen to astronauts there. He also rejected the rumor that the U.S is trying to pull back Russia from ISS.

He further added;
"I strongly believe we're going to get the right answer to what caused the hole on the International Space Station and that together we'll be able to continue our strong collaboration,What we've got to do is we've got to very dispassionately allow the investigation to go forward without speculation, without rumor, without innuendo, without conspiracy." Russian agency said they will not accept any mythical reason until solid proof given…
