A common mineral, α-alumina, found abundantly in Earth's crust, may have played a critical role in initiating the chemical ...

Scientists have made a bold leap in the search for life’s origins, offering a fresh look at how chemistry might have crossed ...

The little spheres represent water molecules. Molecules are in constant motion. The attractions water molecules have for each other keep them close together. They can move past each other, but their ...

Water molecules are so attracted to each other that even after the balloon pops, the water molecules stay together keeping the shape of the balloon. In the water molecule, the oxygen and hydrogen ...

This is because: most of the molecules in food are too large to pass through the absorbing surface of the gut wall the carbohydrates, proteins and lipids are reassembled in the form required ...

Chemical biologists, working with small molecules, expand our understanding of these central elements of life. Chemical biologists ... of the central dogma (Fig. 1). What are small molecules?

A team of scientists just discovered the longest organic molecules yet seen on Mars, the fourth planet from the Sun and and a tantalizing venue for humankind’s search for life beyond Earth.

While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical signatures of past life, if it ever existed. Scientists have announced ...
