An optical sensor that can detect individual molecules promises early detection of diseases and environmental contamination.
You might think the more oxygen you breathe in the better. But too much oxygen can make you sick.
A fetus needs oxygen long before its lungs work and it's exposed to the air. Some ingenious biochemistry explains how the mother's blood delivers it.
Emerging evidence suggests that prolonged stress exposure can accelerate the ticking rate of an internal cellular clock. By doing so, stress can contribute to faster ageing and body deterioration.
Alan Turing's last published paper revealed the mathematics behind the beautiful patterns that adorn the natural world.
Your blood is red;
it's never blue.
Because of hemoglobin;
and the view through tissue.
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.
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 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.
The technique is helping scientists to look for drugs against the Zika virus.
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.
Some people on very low-carb diets say they feel euphoric, have clear minds and lose their appetite. Here's why.
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.
A new theory could explain why the key molecules of life - DNA and RNA - only come in one of two possible forms.
Have you ever wondered how the small white ibuprofen pill turns off your headache? Or how a regular antidepressant keeps your brain chemistry in balance?
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.
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?
