Magic Machine that Produces Oil from Waste Plastic

A Japanese scientist has invented a magic machine that produces oil from waste plastic. This innovation can potentially be solution to plastic disposal problem of a colossal scale.
In this technology plastic is converted into oil using heat and pressure.
This machine appears to have all the traits of a disruptive innovation with effects that could very well shake the global oil market.

ISRO All Set to Launch Astrosat

ISRO is all set to launch its first space observatory 'Astrosat' aimed at studying celestial bodies by the end of September.
SRO's PSLV-C30 will carry the 1.5 ton satellite to place it into a 650-km orbit.
According to ISRO, six customer satellites - one satellite each from Indonesia and Canada, and four nano satellites from the US will ride along with Astrosat.

New Way to Help Map 3D Cosmos

A team of researchers have proposed a new way to chart the cosmos in 3-D.
Researchers proposed a new way to calculate cosmological distances using the bursts of energy also known as fast radio bursts. The method allows researchers to position distant galaxies in three dimensions and map out the cosmos.
These fast radio bursts travel toward Earth, they spread out and arrive at different times based on their wavelengths. The researchers propose using the delay between the arrival times of different frequencies to map the cosmos. The amount of spread in the signal that arrives on Earth gives scientists a sense of how many electrons, and by extension how much material including stars, gas and dark matter, are in between Earth and the source of the burst.

Melting Arctic Sea Ice Affects Land Ecosystems

Melting sea ice may have a direct bearing on methane emissions from Arctic tundra.
As per a study, changes in the Arctic Ocean can affect ecosystems located far away on land.
Bright sea ice reflects most sunlight, while open water absorbs most sunlight. Less sea ice, therefore, leads to more absorbed heat, and higher temperatures throughout the North Pole region.

Invisibility Cloak Developed

Scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have devised an ultra-thin invisibility “skin” cloak that can conform to the shape of an object and conceal it from detection with visible light.
Working with brick-like blocks of gold nanoantennas, the Berkeley researchers fashioned a “skin cloak” barely 80 nanometers in thickness, that was wrapped around a three-dimensional object about the size of a few biological cells and arbitrarily shaped with multiple bumps and dents.
Although this cloak is only microscopic in size, the principles behind the technology should enable it to be scaled-up to conceal macroscopic items as well.
