Nanotubes change the shape of water![]() Houston TX (SPX) Aug 27, 2018 First, according to Rice University engineers, get a nanotube hole. Then insert water. If the nanotube is just the right width, the water molecules will align into a square rod. Rice materials scientist Rouzbeh Shahsavari and his team used molecular models to demonstrate their theory that weak van der Waals forces between the inner surface of the nanotube and the water molecules are strong enough to snap the oxygen and hydrogen atoms into place. Shahsavari referred to the contents as two-dim ... read more |

Light from ancient quasars helps confirm quantum entanglement Boston MA (SPX) Aug 24, 2018
Last year, physicists at MIT, the University of Vienna, and elsewhere provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, can be inextricably linked, in a way that defies the rules of classical physics.
Take, for instance, two particles sitting on opposite edges of the universe. If they ar ... more |
Household phenomenon observed by Leonardo da Vinci finally explained Cambridge UK (SPX) Aug 09, 2018
An everyday occurrence spotted when we turn on the tap to brush our teeth has baffled engineers for centuries - why does the water splay when it hits the sink before it heads down the plughole?
Famous inventor and painter Leonardo da Vinci documented the phenomenon, now known as a hydraulic jump, back in the 1500s. Hydraulic jumps are harmless in our household sinks but they can cause viol ... more |
