A substance found in brown coal can help combat viruses

Scientists from Russia have demonstrated a novel approach leveraging high-resolution mass spectrometry and chemoinformatics to identify biologically active molecular components of humic substances extracted from coal, and ...

Sophisticated molecular machines in action

Almost all living organisms from bacteria to humans have gate-like protein complexes in their cell membranes that get rid of unwanted or life-threatening molecules. This is not always advantageous, since in the case of bacteria ...

Dust storms swirl at the north pole of Mars

Mapping our global human footprint

The number of people flocking to cities in search of employment and better prospects is growing at an unprecedented rate. By 2050, the global population is estimated to reach nine billion, 70% of which will be living in urban ...

Direct atom-resolved imaging of magnetic materials

In conventional electron microscopes, performing atomic-resolution observations of magnetic materials is particularly difficult because high magnetic fields are inevitably exerted on samples inside the magnetic objective ...

Verifying 'organic' foods

Organic foods are increasingly popular—and pricey. Organic fruits and vegetables are grown without synthetic pesticides, and because of that, they are often perceived to be more healthful than those grown with these substances. ...
