Is it always the same?
Your blood is red;
it's never blue.
Because of hemoglobin;
and the view through tissue.
It doesn’t look like a kidney, but this ‘kidney-on-a-chip’ is a breakthrough for new drug testing.
Researchers who've created a kidney-on-a-chip explain why these kinds of devices are an improvement over traditional ways to test new drugs.
Sugar mama? Researchers are teasing out the benefits of various molecules in human milk.
A chemist explains how some molecules in human breast milk help fight infection. Understanding their properties could lead to better infant formulas that share the health advantages of breastfeeding.

Humans have long been trying differentiate themselves from the rest of the biological world. Is it because we're superior, or just insecure?
The ingredients of incense were detailed in the Old Testament.
The four ingredients for holy incense are listed in the Old Testament, but there was much debate over the origin of one of them -- onycha. Scientists think they've now confirmed the source.

Plants make proteins based on whatever genetic material you give them.
Carl Davies, CSIRO
Inserting a random DNA mishmash into a plant or bacterium directs it to make a novel protein. Sifting through the resulting molecules, researchers may find ones have medical or agricultural uses.
A very low-carb diet can prompt changes in your brain similar to that caused by the illicit drug GHB.
Some people on very low-carb diets say they feel euphoric, have clear minds and lose their appetite. Here's why.
Sugar is a surprisingly versatile substance.
Sugar is maligned for its effects on our health, but it's an amazing substance and can be used for more than just making things taste sweet.
The molecules that make up life may have arrived from space, and many are chiral.

Study suggests that comets and meteorites could have seeded planets beyond our own solar system with life.
Scientists have discovered the first easy-to-grow bacteria that can break down plastics.
Tomas Lindahl, pictured here in the lab, along with Paul Modrich and Aziz Sancar, received the Nobel Prize for Chemistry.
The recipients of this year's Nobel Prize for Chemistry showed that DNA is far from static. Rather, it is bombarded by damaging forces, but our bodies know how to repair these precious strands.
The origin of life is still an unsolved riddle. How were life's building blocks first assembled?
Stephens’ banded snake is one of Australia’s few arboreal (tree-dwelling) venomous snakes.
Most people avoid venomous creatures, but they can also teach us a lot about chemical reactions that take place outside of the body - or exochemistry.
Complex but mighty useful.
Scientists and engineers have looked to nature for their inspiration for centuries. The field of biomimetics uses ideas from nature to solve complex human challenges. Synthetic biology, a more recent concept…
People who attribute mental illness to brain disease or genes tend to blame affected people less, but see them as more hopeless and dangerous.
Depression, schizophrenia and other psychiatric conditions are increasingly linked to abnormalities in the brain and in our genes. Many professionals believe these developments hold the key to better treatments…
In them, began life.

How life came about from inanimate sets of chemicals is still a mystery. While we may never be certain which chemicals existed on prebiotic Earth, we can study the biomolecules we have today to give us…
Feeling fruity: the amoeba Dictyostelium discoideum forms ‘fruiting bodies’
Many therapeutic drugs and toxins affect us without us knowing exactly how. We know, for example, that Epilim, or sodium valproate, one of the most highly prescribed medicines for epilepsy can prevent…
