Water molecule discovery contradicts textbook models

Textbook models will need to be re-drawn after a team of researchers found that water molecules at the surface of salt water are organized differently than previously thought.

Chemists tie a knot using only 54 atoms

A trio of chemists at the Chinese Academy of Sciences' Dalian Institute of Chemical Physics, working with a colleague from the University of Western Ontario, has tied the smallest knot ever, using just 54 atoms. In their ...

'Worm-on-a-chip' device could someday help diagnose lung cancer

Dogs can use their incredible sense of smell to sniff out various forms of cancer in human breath, blood and urine samples. Similarly, in the lab a much simpler organism, the roundworm C. elegans, wriggles its way toward ...

Researchers suspend, image single DNA molecules

(PhysOrg.com) -- Studying chemical modifications in the chromosomes of cells is akin to searching for changes in coiled spaghetti. Scientists at Cornell have figured out how to stretch out tangled strands of DNA from chromosomes, ...
