Carbon Dioxide Making Earth Greener

A new research shows that the earth is getting greener because of higher carbon dioxide (CO2) levels in the atmosphere.
Observations over the past 33 years show that there has been a steady increase in leaves on plants and trees.
The amount of CO2 in the air has been increasing since the industrial age and currently stands at a level not seen in at least half-a-million years.

New State of Water Molecule Discovered

Scientists have discovered a new state of water molecule.
This discovery reveals that water molecules tunnel in ultra-small hexagonal channels (measuring only 5 angstrom across) of the mineral beryl. Basically, this means the molecules spread out when they are trapped in confined spaces, taking a new shape entirely.
The tunneling state of water breaks the rules of known fundamentals seen in gas, liquid, or solid state. The discovery describes the behaviour of water molecules present in tightly confined areas such as cell walls, soils and rocks.

Interstellar Dust Detected for First Time

NASA's Cassini spacecraft orbiting Saturn has detected and analysed the faint but distinct signature of interstellar dust coming from beyond our solar system.
The tiny dust grains were speeding through the Saturn system at over 72,000 km per hour.
The composition of the dust has been analysed for the first time, showing it to be made of a very specific mixture of minerals not ice.

Kepler Enters Emergency Mode

This is the second time that Kepler spacecraft has placed itself in emergency mode.
NASA received a transmission that Kepler had entered emergency mode.
Kepler spacecraft which is now on its extended mission K2 was launched in 2009 with the goal of finding candidate planets outside our solar system. It achieved major success in 2012 for discovering nearly 5,000 exoplanets.

Mysterious New State of Matter Detected

A team of scientists has detected a mysterious new state of matter that causes electrons -- thought to be nature's indivisible building blocks -- to break into pieces.
The state, known as a quantum spin liquid, was found in a two-dimensional material with a structure similar to graphene.
It was first predicted 40 years ago, quantum spin liquids were thought to be hiding in certain magnetic materials, but had not been conclusively sighted in nature.
