We are often confronted with a facial expression that makes us feel uncomfortable or we sense there is something wrong. Most of us don’t go further than saying, “That just doesn’t seem right,” or, ...

Sometimes the difference between life-saving drug and deadly side effect is chirality. L-DOPA is the best drug we have for Parkinson’s disease. If you take L-DOPA and reflect it in a mirror, you get a ...

Hold out your hands, palms up, and move them so they are on top of each other. With a little experimentation—and perhaps a few rather flamboyant gestures—you'll find that no matter what you do, your ...

In this episode of Tiny Show and Tell Us, we cover why your body feels so ‘off’ at high altitudes and how we’ve evolved not to detect low oxygen levels but high amounts of carbon dioxide. Then we ...

This module has been designed to introduce second-year organic chemistry students to the concepts of stereochemistry through the lens of the World Health Organization’s Model List of Essential ...

In our high school chemistry classes we all learn about chirality, the property of organic molecules in which two chemically identical molecules can have different structures that are mirror images of ...

In the past several decades, significant progress has been made in controlling molecular chirality, as evidenced by the several Nobel Prizes in chemistry awarded in this area, particularly for ...

The chirality lies in the geometry Scanning electron microscopy (SEM) image of nickel-based artificial chiral magnets fabricated at EPFL’s Center of MicroNanoTechnology. (Courtesy: Mingran Xu, Dirk ...
