Got rope? Then try this experiment: Cross both ends, left over right, then bring the left end under and out, as if tying a pair of shoelaces. If you repeat this sequence, you get what's called a "granny" knot. If, instead, ...

(Phys.org)—A group of chemistry researchers working in a lab at Cambridge University have succeeded in causing a group of molecules to form themselves into trefoil knots. The team was working on combinatorial chemistry ...
A quantum gas can be tied into knots using magnetic fields. Our researchers were the first to produce these knots as part of a collaboration between Aalto University and Amherst College, U.S., and they have now studied how ...

A team of researchers at the University of Manchester has created the most tangled interlocked molecule ever. In their paper published in the journal Nature Chemistry, the group describes creating the knot and their hope ...
The structure and functions of many physical networks, including the human brain, the vascular system and other biological networks, often depend on their three-dimensional and geometrical layout. Distinguishing between physical ...
An international team of astronomers have employed India's AstroSat spacecraft to observe a system of interacting galaxies known as NGC 5291. Results of the observational campaign, published April 6 in the Monthly Notices ...
