No More Animal Testing

Product testing on animals is a practice that is firmly looked down upon and highly condemned. In some cities around the world, it is also a forbidden act.
Now, to curb such a situation and keeping in mind the safety of animals, researchers have developed a new 'organs-on-chips' technology that could replace animals for testing new drugs or supplements.
The flexible polymer organ-chips contain tiny channels lined with living human cells and are capable of reproducing blood and air flow just as in the human body.

Ingredient for Life at Saturn's Moon Enceladus

The US space agency NASA's Cassini spacecraft has discovered hydrogen in the plume of gas and icy particles spraying from Saturn's sixth largest moon Enceladus.
The finding provided further evidence that warm, mineral-laden water is pouring into the ocean from vents in the seafloor.
Enceladus now appears likely to have all three of the ingredients scientists think life needs: liquid water, a source of energy such as sunlight or chemical energy, and the right chemical ingredients like carbon, hydrogen, nitrogen, oxygen.

One of the Most Ultra Distant Galaxies

Astronomers have discovered one of the most distant galaxies in the universe that belongs to about 13.1 billion years in the past, a period just 700 million years after the Big Bang.
These ultra distant galaxies, seen as they were close to the beginning of the universe, are interesting because they fall within the "Epoch of Reionisation," a period about a billion years after the Big Bang when the universe became transparent.

Ultrafast Flexible and Transparent Memory Device

Scientists have developed the quickest, smallest, highest-capacity memory device that could pave the way for the next generation of flexible and transparent electronics.
The new memory devices may also have the potential to offer a cheaper and more adaptable alternative to 'flash memory', which is currently used in many common devices such as memory cards, graphics cards and USB computer drives.

ISRO Embraces Private Sector

The Indian space establishment has crossed a new threshold, engaging for the first time a private sector industry to make a full multi-crore, heavy duty satellite.
Having been unable to keep pace with satellite fabrication, ISRO has now roped in the private industry to bridge the gap.
A consortium led by Alpha Design Technologies, Bengaluru is tasked to make two full satellites for India's navigation system.
After almost 150 missions and three decades of space faring, the ISRO is on a mission like never before, handholding the private industry to make a full navigation satellite.

Neptune-sized Lost Planet Discovered

Astronomers have discovered a lost planet which they claim is about the size of Neptune about 3,000 light years from Earth.
The new planet, Kepler-150 f, was overlooked for several years.
Kepler-150 f takes 637 days to circle its sun.
The Kepler Mission found four other planets in the Kepler-150 system - Kepler-150 b, c, d, and e - several years ago. All of them have orbits much closer to their sun than the new planet does.
