How do memories last a lifetime when the molecules that form them turn over within days, weeks or months? An interaction ...

If you take two objects with fairly smooth surfaces, and put these together, you would not expect them to stick together. At ...

The biosynthetic pathways leading to such bonds can be bypassed through chemical synthesis to synthesize natural products more efficiently and also to generate the molecular diversity unavailable ...

When Todd Sacktor (opens a new tab) was about to turn 3, his 4-year-old sister died of leukemia. “An empty bedroom next to mine. A swing set with two seats instead of one,” he said, recalling the ...

This review introduced a novel concept for host-guest systems, named “controllable ultrahigh-affinity molecular recognition”.

Each atom then has a complete outer shell of electrons. The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule ...

According to PAP, citing information from the scientific journal Nature, a covalent bond that requires only a single electron is the first new chemical bond to be discovered in over ten years.
