A new water loss mechanism on Venus explains how the planet lost all its water, turning the planet from a potentially habitable world into the parched hellscape we know today. Scientists have ...

A 'cage of cages' is how scientists have described a new type of porous material, unique in its molecular structure, that could be used to trap carbon dioxide and another, more potent greenhouse gas.

Show more The Earth is alive because of liquid water and the success of our human story is intimately connected to our relationship with this simple molecule. But the growth of our civilisations ...

The number of each atom collected is shown in the "Atoms Collected" area of the side panel. To create a molecule, make sure you have the right number of each atom and then select the correct “Create ...

The Spanish research team succeeded in synthesizing a sandwich molecule that contained not one but two metal atoms. For a long time, this "dimetallocene" containing two zinc atoms remained the ...

Deoxyribonucleic acid (DNA) is a molecule that encodes an organism's genetic blueprint. In other words, DNA contains all of the information required to build and maintain an organism. DNA was ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

A unit of enzyme activity is defined as the amount of enzyme required to liberate 1 mμmole of hexose per hour. Results are expressed as units of activity per milligram of protein, which was ...

And while the double helix was certainly groundbreaking in its time, the current generation of scientific history will be defined by a different (and, until recently, lesser-known) molecule – one that ...

Residues such as wood chips, sugar cane bagasse and corn cobs contain cellulose and can be transformed into biofuel when submitted to hydrolysis, a chemical molecule-breaking process ... formed by six ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...
